Sheehan,
Welcome
Chair
Welcome to the first issue of Big Blue World for 2025. Without tempting fate with the bad weather demons, winter is almost behind us here in Scotland. As we rush into spring, I can reflect on the hectic start we’ve had to the year.
Since taking over as Chair of the Aberdeen branch, we have held our annual quiz night and AGM, a business breakfast, two evening meetings, supported Subsea Expo, and organised a careers event in collaboration with SUT+ colleagues and Aberdeen University—all within just two months! It has been a very active start, and one I have certainly enjoyed.
I have witnessed first-hand the ability of the SUT family to bring together people from all generations. Our February branch meeting focused on saturation diving—an aspect of our underwater capabilities that is often taken for granted. It was our best-attended meeting since lockdown, drawing a great crosssection of individuals, from industry veterans keen to reconnect with peers to early-career professionals eager to expand their knowledge. I was particularly struck by the speaker from Boskalis Subsea Services, who delivered an enlightening presentation on how modern medical practices have been adapted to enable divers to perform effective CPR in the cramped confines of a diving bell at depth. Remarkably, this technique had remained unchanged in diver training for almost 70 years. The fact that such a potentially life-saving method had been overlooked for so long serves as a reminder that we can always learn from others.
With the SUT branch well established in the Aberdeen area for over 30 years, we benefit from a strong committee and the continued support of our corporate members. However, like most other regions, we find ourselves navigating several transitions. Regardless of political sentiment, the energy transition is clearly upon us. We must balance the underwater aspects of our hydrocarbon legacy with an increasing focus on renewable technologies. I believe this presents a fantastic opportunity for our sector to thrive, with the Society playing a key role as an educational champion.
Another transition we are experiencing locally is generational. An industry that grew from strength to strength in the ’90s and early 2000s is inevitably seeing experienced practitioners retire, creating space for younger professionals to step up, bringing fresh perspectives and renewed vigour to shape the Society’s future.
As Chair of the branch, I find myself at the heart of both transitions—too old for late nights but not yet ready for pasture! Despite losing some of our more seasoned committee members, we have successfully recruited younger members who are active in both oil and gas and renewables, ensuring a strong and balanced future for the branch.
In this issue of Big Blue World, you’ll find a diverse range of articles that highlight the multi-faceted nature of the underwater sector and the importance of maintaining a mindset of continuous learning.

Subsea Expo 2025
Aberdeen, February 2025 | Cheryl Burgess
The Subsea Expo took place at P&J Live in Aberdeen in February. For SUT it was an opportunity to talk marine, subsea and underwater technology while meeting both existing members exhibiting and visiting the event highlighting the potential of the Blue Economy sectors, as well as students, those speaking in the conference and friends old and new. It was a particular pleasure to welcome students to the SUT stand. A careers clinic was available to university attendees, which attracted undergraduates from the University of Aberdeen and Strathclyde University. SUT also took place on the student trail which had younger students participating in the Subsea Expo inspiring the next generation to have an up close and in-person experience showcasing the career potential in the underwater sectors. The visiting school groups had questions to ask at each stand on the trail. Students visiting the SUT stand were asked, ‘Who was Cornelius Drebble’? For those who haven’t been on the SUT Subsea Awareness Course (SAC), Cornelius Drebble built the world’s first practical and working submarine in 1620 under the patronage of James 1st of England.
We are already looking forward to Subsea Expo 2026.
Global delegates gain hands-on insight at SUT Subsea Awareness Course
The SUT Subsea Awareness Course was successfully conducted in Aberdeen in early February 2025 and welcomed delegates from around the world.
This course continues to draw professionals eager to gain insight into the unique challenges of the subsea industry, learning from experts with extensive experience and knowledge.
A standout feature of the SUT offering is the opportunity for site visits, where delegates can experience subsea equipment firsthand. These visits provide a deeper understanding of the size, complexity, and intricacies involved in the design, manufacturing, installation, and
operation of subsea technologies.
The site visits were supported by SUT sponsors, including Baker Hughes, where participants had the chance to observe subsea trees and wellheads; SLB Subsea, showcasing control systems; and Fugro, offering insights into intervention challenges and the future of remote operations. On the final day, delegates visited the UK National Decommissioning Centre, where they explored future challenges and experienced the benefits of operational simulations in their state-of-the-art, fully immersive, four-operator interactive simulator. This course is held in Aberdeen four times a year.
OnDeck’s AI Revolutionises Underwater Footage Analysis with Human-Like Precision
A new AI method pioneered by OnDeck can find and understand anything in underwater footage, just like a human. Peer-reviewed and published at NeurIPS 2024, the software allows users to search across any type of camera or environment - without requiring labelled training data. Offshore industry and subsea technology companies can leverage this system to automate all video and imagery analysis, streamlining decision-making for site investigations, impact assessments, infrastructure
inspections, exploration, and more. This breakthrough was supported by $1.5M from National Geographic, Schmidt Marine, and Canada’s Ocean Supercluster to tackle long standing challenges in automating vision across dynamic underwater conditions.
The online research preview is free to use through April via OnDeck Fisheries AI’s website.
CONSUB announces new valve release capabilities for 2025
Following success with its onshore/topside valve release service, CONSUB is excited to announce the imminent launch of a new subsea valve release capability, to bring the proven technology below the waterline.
With pressures on the energy sector the CONSUB Field Services team has delivered success for clients on numerous offshore and onshore valve release projects, both UK and globally. This inspired CONSUB to adapt their tool design to take the seized valve release service subsea.
CONSUB Centre of Excellence for Valves
Throughout 2024, the expertise of the CONSUB Centre of Excellence for Valves was regularly called upon. Stuck or seized valves proved to be an issue for many operators, particularly on late-life infrastructure in the UK Continental Shelf. Reliable operation of valves is critical: any loss in functionality is a concern for safety and operational efficiency.
The Impact of Stuck Valves
A recurring theme was the impact of an inoperable valve on isolations and planned shutdowns. Even the most comprehensive shutdown plans are worthless
if a valve will not actuate on demand. All too often this leads to an expansion in required isolations, bringing cost, safety and process implications.
However, developments and innovations in the field of valve remediation offered a beacon of hope. With the CONSUB Valve Release System (C-VRS), the team deployed to facilities on numerous occasions to restore the functionality of safety critical valves.
CONSUB Valve Release System
The mechanical C-VRS is safe to use in hazardous environments and requires no process isolations. The amount of torque applied is low, controlled and limited, meaning the tool is “Valve Safe”. Previously inoperable valves have been entirely remediated, axing the scope and impact of process isolations, and bringing significant financial savings.
The team is excited to launch a subsea, diver-operated variant of the C-VRS to remediate stuck valves in the subsea environment.

Tidal Lagoon Optimisation to Maximise Energy Generation
Tidal energy remains a significantly under-utilised renewable energy resource, despite the UK possessing up to half of Europe’s exploitable tidal resources. Wales, with its abundant tidal range potential and existing industrial capabilities, is uniquely positioned to spearhead the development of tidal lagoon power stations. These systems offer a predictable and renewable energy source that can complement the intermittent generation of wind and solar energy. Recent advancements highlight the potential for optimising tidal lagoon designs and operational strategies to enhance energy yields and economic attractiveness.
However, existing studies reveal a gap in evaluating the long-term operational benefits of flexible schemes and co-location with other renewable sources. Furthermore, understanding the hydrodynamic interactions between multiple lagoons and their response to climate change scenarios remains a critical research need. Addressing these gaps is essential to maximising the economic, environmental, and energy potential of tidal lagoon projects.
Intertek Metoc has partnered with ORE Catapult and Cardiff University on the Welsh Government’s Tidal Lagoon Challenge project to assess the long-term value of tidal lagoons, focusing on their integration into future decarbonised energy networks and exploring their role in addressing dynamic electricity demand and pricing structures.
Commissioned in mid 2024, this study aims to make tidal lagoon systems in Wales more economically attractive, focusing on three case studies: the North Wales Tidal Lagoon, Cardiff Tidal Lagoon, and Newport Tidal Lagoon as shown on the map. Configuration
optimisation has been carried out to refine design parameters, including turbine types (comparing the Andritz Hydro three-blade turbine and the Tidetec turbine), turbine diameters, turbine numbers, installed capacities, and sluicing areas. Operation optimisation has been achieved using genetic algorithms to explore flexible operation schemes that significantly enhance energy output and economic performance.
Traditionally, the operational heads are set as a pair of constant values for flooding and ebbing tides during spring and neap tides. This may result in a loss of tidal power if the water head difference inside and outside the lagoon is insufficient to reach the set head, particularly during neap tides. The flexible operation schemes use optimisation methods to apply variable operational heads for each tidal cycle, fully exploiting the potential of tidal power to achieve multiple objectives, including maximising energy generation.
For example, in the case of the North Wales Tidal Lagoon, the results indicate that optimisation significantly increases the estimated energy generation by up to 40%. The study further employs two-dimensional (2D) Delft3D modelling to simulate hydrodynamic interactions between the Cardiff and Newport lagoons, verifying the 0-D optimisation results.
Additionally, this project investigates the longterm performance of these systems under climate change scenarios for the years 2035, 2085, 2135, and 2185, providing insights into future resilience and adaptability. The outcomes of this modelling will subsequently be used to evaluate the supply chain and economic aspects. This study underscores the
potential of tidal lagoon developments in enhancing energy generation, storage, and economic benefits, fostering a sustainable and resilient energy future for the UK and beyond. The optimisation results demonstrate that configuration optimisation and flexible operation schemes (including pumping) can significantly increase energy output, making tidal lagoons more economically attractive.
Simulating climate change scenarios helps to better understand the long-term feasibility of these systems,
addressing uncertainties associated with sea level rise and hydrodynamic behaviour. By analysing cost benefits, hydrodynamic interactions, and future adaptability, this research supports the strategic design and deployment of tidal lagoons, contributing to energy security, carbon reduction, and local economic development. The findings will provide essential evidence for developing policy frameworks and cost mechanisms to incentivise tidal range projects in the UK.
Autonomous Acoustic Profiling with Marine Renewable Energy
To advance deepwater soundscape exploration, Kaustubha (Kaus) Raghukumar of Integral Consulting Inc. is leading a research team from SEATREC Inc., Proteus Technologies LLC, Monterey Bay Research Institute, the Naval Postgraduate School, and the Scripps Institution of Oceanography to develop and demonstrate the first ever autonomous, near real-time, directional acoustic profiling float powered by marine renewable energy.
The underwater soundscape consists of a complex mix of physical, biological, and anthropogenic sources that often have very different characteristics. While most sounds are well-characterized on continental shelves and near populated regions, there is a marked paucity of acoustic data at full

ocean depths, primarily due to the logistical challenges in deploying and recovering traditional acoustic sensing platforms in difficult-to-reach regions of the world’s oceans. This project will result in a near real-time, ocean thermal energy conversionpowered, directional acoustic profiling float navigated using ocean model output for explorations of the ocean through persistent, long-endurance, deep-water ocean acoustic observations. Directional profiling float measurements will consist of acoustic pressure and particle motion at low- to midfrequencies relevant to many biological and physical processes, anthropogenic sources, and geophysical processes, along with complementary physical oceanographic parameters.
The NoiseSpotter® features a small (4 × 4 × 4-ft) three-sensor array, with each sensor measuring acoustic pressure and particle velocity to geolocate sources of sound more efficiently. Each sensor is housed inside a flow noise suppression shield to improve signal-to-noise for collection of robust acoustic data in energetic conditions.

AOE Rock Bag JIP Phase 2
The latest update meeting for the Rock Bag JIP Phase II was held in December 2024 with representatives from UK, Europe, and Western Australia. The participants were updated on the completed dry testing scope, and the first stage of wet testing, which involved consideration of rock bags (Filter Units) on erodible seabeds.
The dry testing of the mass transfer of a model rock
(b) Offset = 40% RB Diameter
bag (RBs) to a cable was undertaken at UWA’s Coastal Offshore Engineering Laboratory (COEL). The testing considered effects due to RB fill ratio, fill material, multi-bag configurations, and placement tolerances over a range of model cable diameters. This builds knowledge of the application of RBs as secondary stabilisation for cables and CPS subsea. This involved some 1700 individual tests. These tests have provided valuable quantitative data on RB performance that can be integrated with the failure envelopes developed previously.
Offset Rock Bag Tests
The testing builds upon earlier work in which a strong focus was given towards developing new insights into the hydrodynamic behaviour of RBs under various flow conditions. This led to the development of a RB and cable failure envelopes for which the point of failure could be predicted given a flow velocity, or cable load imposed on the RB.
The figure below presents measured failure envelopes for two types of RB’s. Increasing the hydrodynamic loading reduces the cable load required to induce failure. Interestingly, multiple failure mechanisms were observed, occurring under varying hydrodynamic loading and cable loading relationships, as well as being influenced by the surface roughness and intrinsic properties of the RB model.
(a) Offset = 20% RB Diameter
Update
The UWA O-Tube Test Facility
This scope of work is focused on the influence of sediment transport on the stability of a RB, with assessments being made on infiltration rates, scour profile developments, and stability of RB near scour holes. The test scope includes:
l Coefficient of friction testing to update current industry assumptions
l Infiltration assessment under varying flow conditions modelling both clear water and live bed scour conditions.
l Scaling assessment for post processing of data
l Modelling of scour profiles using photogrammetry techniques developed under the varying flow conditions.
l Influence on the hydrodynamic stability of the RBs models, measured through assessing the RBs critical velocity.
l Assessing multibag RB configurations
l Assessing the stability of a rock bag in proximity to pre-existing scour holes.
Upcoming testing will focus on measuring the hydrodynamic coefficients of isolated RBs, RBs on cables, and multibag RB configurations. With currently seven participants (Bluemont Australia, CRP, DEME, Nexans, JDN, Ridgeway Rockbags®, TenneT, Van Oord), the JIP would welcome the addition of further participants. Please contact AOE if you would like further information on this JIP, or on how to join it.

Unveiling a New Perspective: Exclusive True-Colour Image of Endurance Shipwreck Released
Voyis and the Falklands Maritime Heritage Trust reveal unprecedented details of the legendary vessel using advanced optical technology.
the historic Endurance shipwreck. Captured using the cutting-edge Voyis Observer Imaging System, this latest image provides an unparalleled view of the vessel and the seabed, revealing intricate details with clarity never seen before.
The level of detail we can now see allows us to deepen our understanding of Endurance’s condition and better appreciate the remarkable state of preservation of this legendary vessel.”
Building on a previously released image of Endurance, this new capture showcases the ship’s preserved structure with remarkable precision, made possible through Voyis’ True Colour technology. Unlike traditional underwater imaging, which can suffer from colour distortion and reduced visibility, the Voyis Observer Imaging System accurately restores the shipwreck’s natural hues and textures, offering a more authentic representation of how Endurance appears in its final resting place beneath the Weddell Sea.
Since red wavelengths are absorbed more rapidly by
water, the perceived colour of underwater objects is significantly altered. Standard cameras do not compensate for this underwater colour shift, as their colour formation models neglect the strong wavelength dependency of light in a submerged environment. As a result, shipwrecks and subsea assets often appear with unnatural blue or green tints.
Voyis’ True Colour technology addresses this challenge by leveraging machine learning to efficiently train a Colour Correction Model for the current survey location. This survey-grade imaging solution corrects the distortions caused by underwater light absorption, producing images that represent colours as they would be perceived in air. This advancement allows explorers to visualize the true colour of subsea assets, uncovering fine details that standard cameras fail to capture.
“This new image is a testament to the evolution of
AFTER The Ship Beneath the Ice
Over one hundred years after its wreck, Endurance, Sir Ernest Shackleton’s ship, was found in the depths of the most hostile sea on Earth. The Ship Beneath the Ice is the astonishing story of the ship and its discovery, told by Mensun Bound, the Director of Exploration on the Endurance22 Expedition.
‘The story of Shackleton’s Endurance is one of the most extraordinary in the history of exploration. This is more than just an astonishing sequel. It is a tale just as powerful, and one which redefines the meaning of impossible’ – Sir Michael Palin CLICK HERE to get the book.
underwater exploration technology,” said Elena Lewendon, COO at the Falklands Maritime Heritage Trust. “The level of detail we can now see allows us to deepen our understanding of Endurance’s condition and better appreciate the remarkable state of preservation of this legendary vessel.”
Voyis’ Observer Imaging System was designed to overcome the challenges of deep-sea imaging by delivering high-resolution optical data with true colour fidelity.

Leading Marine Conservation: Lessons from Lyme Bay and the Fish-Intel Network
As we strive to protect 30% of the ocean by 2030, the lessons learned from the UK’s best example of a continuous, long-term Marine Protected Area monitoring study are clear – conservation works best when it’s inclusive, grounded in evidence, and designed to meet the needs of both ecosystems and people. Insights from two University of Plymouth initiatives are shaping the future of marine conservation: the Lyme Bay monitoring programme and the Fish Intel under water acoustic receiver network. These projects highlight how evidencebased approaches can drive ecological recovery while benefiting fisheries and coastal communities.
Lyme Bay as a model for whole-site protection
Since 2008, the Lyme Bay Marine Protected Area has been protected from bottom-towed fishing, creating space for the ecosystem to recover. Over 16 years of continuous annual monitoring, we’ve seen remarkable ecological gains: reef species abundance has increased by 95%, and fish diversity and abundance are up to 400% higher compared to unprotected areas.
These ecological advances suggest the potential for broader benefits, including burgeoning fish populations that can contribute to sustainable fisheries in surrounding areas. The recovery of commercially valuable species such as lobster and scallops within the protected area demonstrates the value of safeguarding marine habitats for biodiversity and livelihoods alike. By taking a whole-site approach—protecting the entire ecosystem rather than focusing on individual features—we’ve shown how conservation can support
Personal Bio: Emma Sheehan
Dr Emma Sheehan, from the University of Plymouth, has been researching the ecological impacts of the Lyme Bay Marine Protected Area since 2008, in what is considered to be the best example of a continuous long-term MPA monitoring study in the UK.
Now, Dr Sheehan, together with ‘Ropes to Reefs’ Project Manager Amy Cartwright, gives her thoughts on lessons learned from this wholesite approach to marine conservation, and how state-of-the-art sensor technology can provide the evidence needed to drive ecological recovery for the benefit of fisheries and communities.
both ecological restoration and the resilience of coastal communities. Lyme Bay offers a hopeful model for balancing marine protection with sustainable resource use.
Tracking marine connectivity using the Fish Intel Network
The Fish Intel Network expands on the local focus of our Lyme Bay monitoring by exploring how marine species move across larger areas. Using around 200 underwater receivers and data from over 1,500 tagged fishes and crustaceans, our acoustic telemetry is uncovering patterns in the movements of species like European bass, pollack, rays and

lobster along the south coast of the UK and beyond. Crucially, the work involves close collaboration with local fishing communities and by working together we have identified 13 million individual animal detections across six years of continuous data. This information is vital for effective fisheries management. By identifying critical habitats, migration routes and seasonal behaviours, we can inform ambitious management and policy that align with the natural rhythms of marine species. For example, protecting spawning and nursery grounds at the right time to help safeguard key life stages while supporting sustainable fishing practices.
The need for long-term investment
Despite the progress made, the future of the Lyme Bay project and the Fish Intel Network remains uncertain due to funding challenges. Long-term monitoring and telemetry projects need consistent support to maintain their impact. Without it, we risk losing the data that underpins effective conservation and fisheries management.
This isn’t just about funding research; it’s about ensuring the resilience of marine ecosystems and the wellbeing of the communities that rely on them. Looking ahead, it will be vital to consider how we can continue to support projects like these to secure a sustainable future for our oceans and coastal communities.

Holistic Approach to Determine an Optimal
The installation of pin piles is a critical component of jacket foundation installation, providing the necessary stability for wind turbines. Achieving an optimal installation method requires a holistic approach that considers various factors, including project-specific details, vessel capabilities and installation efficiency. This article explores these factors in detail to help determine the best installation method for pin piles.
Project-specific parameters
Every offshore wind project is unique, with specific requirements and challenges that must be addressed. Key project-specific details include the location, water depth, soil conditions, and environmental factors. Understanding these details is crucial for selecting the appropriate installation method.
l Location: The geographical location of the project influences the choice of installation method. For example, projects in regions with high seismic activity and chances of typhoons, such as Taiwan or Japan, may require more robust foundation designs and installation techniques to withstand potential earthquakes and extreme wind loads. Additionally, each country has its own regulatory framework. For example, Japan and the United States have protective legislation that restricts the operation of foreign vessels in their waters.
l Water depth: The depth of the water at the installation site affects the type of equipment and vessels needed. Shallow water installations may allow for the use of jack-up vessels, while deeper water projects might require floating vessels and specialized equipment. Floating vessels require self-leveling piling templates which are more complex than suspended templates underneath a jack-up vessel.
l Soil conditions: The seabed composition, including the type of soil and its bearing capacity, plays a significant role in determining the installation method. Detailed geotechnical surveys are essential to gather data on soil conditions, which can influence the choice of pin pile design and installation technique. For example, Taiwan’s offshore wind projects face challenges with low bearing soil conditions, while France’s diverse soil conditions range from sandy and silty soils to rocky seabeds. Low bearing soil conditions might results in challenging piling template seabed interface, while rocky seabeds require drilling solutions.
l Environmental factors: Weather conditions, wave and current patterns, and the presence of marine life can impact the installation process. For instance, larger pin piles tend to vibrate with lower wave frequencies, which can affect the installation operability. Conducting motion analyses or workability analyses is essential to account for these factors and ensure a safe and efficient installation.
Optimal Method for Installing Pin Piles
Vessel capabilities and cost
The capabilities and availability of installation vessels are critical considerations in the installation process. Different vessels have varying capacities, equipment, and operational limits, which can affect the feasibility and cost of the installation method.
l Vessel type: The choice of vessel depends on the project requirements and site conditions. Jackup vessels are commonly used for shallow water installations, providing a stable platform for pile driving. Floating vessels, on the other hand, are suitable for deeper waters and can accommodate larger equipment.
l Vessel availability: The availability of suitable vessels can impact the project timeline and costs. A shortage of specialized vessels can lead to delays and increased expenses. Past installation methods, primarily reliant on Jack-Up Vessels (JUVs), have proven effective but are currently facing limitations in handling the demands of longer, larger, and heavier piles. However, the shortage of heavy lift vessels capable of installing these larger pin piles is a pressing concern.
l Operational costs: The cost of operating installation vessels includes fuel, crew, and maintenance expenses. These costs can vary significantly depending on the vessel type and the duration of the installation process. Optimizing installation sequence and minimizing
downtime can help reduce overall costs.
Installation efficiency
Efficiency in the installation process is crucial for minimizing project timelines and costs. Several factors contribute to installation efficiency, including the choice of equipment, installation techniques, and project management.
l Tailored installation equipment: The selection of installation equipment, such as pin pile templates and lifting devices, can impact the speed and accuracy of the installation. Tailoring equipment design to the specific needs of the project can enhance efficiency.
l Installation method: Different installation methods, such as pile driving and drilling have varying levels of efficiency and suitability for different soil conditions. Selecting the right method based on project-specific details can improve installation efficiency.
l Project management: Effectively managing the project’s budget, planning, risk control, QHSE requirements, and procurement, along with detailed project management practices such as planning, scheduling, and coordination, is essential for ensuring smooth project execution. Real-time monitoring and adjustments can help address any issues that arise during installation, minimizing delays and disruptions.

Aberdeen Business Breakfast
4 February 2025 | Marcliffe Hotel, Aberdeen |
Martin Harley
A total of 44 attendees joined us very early on a mild February morning at the Marcliffe at Pitfodels Hotel in Aberdeen for the Society’s 2025 Business Breakfast & Market Outlook, titled High Stakes.
Once again, our speakers were James Hall of Axiom EMI, Catherine MacFarlane, and Ross Macdonald of S&P Global. They revisited some of their predictions from a year ago, updating us with new information in the wake of the UK and US elections. Indeed, we were pleased to see some familiar faces in the audience from last year and presume this is because our speakers are saying the right kind of thing.
Chair Martin Harley opened the event, setting the scene with a few recent developments that served as a backdrop to the two talks we were about to hear. He covered topics including the fall of the Norwegian government, triggered by a tenfold increase in energy prices due to the need to supply gas to a Europe that refused to produce its own; the fact that European gas storage was abnormally low in a winter that has not yet finished; and the contradiction between claims that renewables are cheap and data showing that UK wind farms funded by Contracts for Difference received more revenue from subsidies than from selling the electricity they generated.
James Hall of Axiom EMI presented a number of oil price and CAPEX predictions from various analysts, banks, and international NGOs. He then outlined his current confidence in Net Zero becoming a reality by 2050 before moving on to the global renewables buildout, oil and gas tree, fixed and floating installations, and commentary on overall offshore spending across both fossil and renewable sectors. He demonstrated that, from a variety of perspectives, the energy industries were in robust health and likely to remain so.
Catherine MacFarlane and Ross Macdonald of S&P Global both covered the global fleet, starting with a review of Diving Support Vessels before moving through a variety of other construction and offshore support vessels. The overall picture was one of reduced DSV availability but an increase in construction support vessels, meaning we should expect rates to change accordingly. Meanwhile, vessels built specifically for the wind industry have become a competitive option for oil and gas services.
All three speakers delivered information-dense analyses of the offshore energy markets, and we would like to thank each of them for continuing to speak on the SUT’s behalf.

Diving - Research, Practice and Safety Aberdeen Evening Meeting
12 February 2025 | Aberdeenshire Cricket Club | Graham Whitehead
The Aberdeen Branch recently welcomed around 60 attendees, representing a broad cross-section of experience, to Aberdeen Cricket Club for an evening meeting on Diving – Research, Practice and Safety.
Graham Whitehead opened the meeting, highlighting that while remote technologies are commonly used in underwater operations, manned diving remains essential across the globe, with over 70 dive support vessels (DSVs) currently active. He noted the risk of hard-earned knowledge being lost as the average age of saturation divers increases. This meeting was therefore designed to share expertise among current practitioners while also informing attendees less familiar with diving operations.
Bill Chilton of IMCA shared insights from a North Sea diving incident, drawing lessons for underwater cutting operations. His talk reflected on a commercial diving incident that occurred during a subsea decommissioning project while he was at the UK’s Health & Safety Executive. The presentation examined what went wrong, what could have been done differently, and how the incident influenced changes in the UK commercial diving industry. Some attendees were already familiar with the event and its findings, agreeing that lessons had been learned. The speaker also explained how he had presented these lessons to dive teams in other global regions unfamiliar with the incident, reinforcing the continued need for experiential knowledge sharing.
Graeme Robb of JFD Group covered the topic of modern hyperbaric rescue facilities, which are critical safety systems for saturation divers in the event of an emergency evacuation from a DSV. Thankfully, no operational incident has ever required the deployment of such facilities. However, given the complexity
and life-threatening nature of such an operation, technological advancements—such as mobile decompression facilities—are continually improving safety measures.
Mario Gagliardini of Boskalis Subsea Services delivered an eye-opening presentation on the challenges divers face if they need to perform CPR on a colleague inside a diving bell at depth. In collaboration with doctors and resuscitation professionals from Derby University Hospital, a new method known as the Dunoon Protocol has been developed using the latest medical practices. This approach has recently undergone trials and is expected to become a cornerstone of saturation diver safety and industry standards. The presentation also covered ongoing research into enhancing recovery systems and the potential use of defibrillators in diving bells.
Calum Miller of BP presented a case study from a recent diving campaign, illustrating the complexities of mid-water diving. His talk covered key operational challenges, including DSVs operating in close proximity to fixed installations, complex rigging arrangements, and the control and communication required during load transfer activities. Success factors included methodical and detailed risk assessments, the use of 3D visualisation to design rigging and familiarise crews with the complexities of in-water activities, and effective SIMOPS coordination between the vessel and platform.
Graham Whitehead closed the meeting by thanking the speakers and attendees for braving the cold February evening. The turnout and high level of engagement underscored the ongoing need for collaboration and knowledge-sharing within the commercial diving community.
