The March of the Penguins 4

Shell has announced a final investment decision on the redevelopment of the Penguins oil and gas field in the UK North Sea. The decision authorises the construction of a floating production, storage and offloading (FPSO) vessel, the first new manned installation for

Shell in the northern North Sea in almost 30 years.

The redevelopment is an attractive opportunity with a competitive goforward break-even price below $40 per barrel. The FPSO is expected to have a peak production (100%) of circa 45,000 boe/d.

UT3 Issue 6 December 2017 January 2018

The Penguins field currently processes oil and gas using four existing drill centres tied back to the Brent Charlie platform.

The redevelopment of the field, required when Brent Charlie ceases production will see an additional eight wells drilled, which will be tied back to the new FPSO vessel. Natural gas will be

exported through the tie-in of existing subsea facilities and additional pipeline infrastructure.

The Penguins field is in 165m (541 ft) of water, approximately 150 miles north east of the Shetland Islands. Discovered in 1974, the field was first developed in 2002 and is a joint venture between

Shell (50% and operator) and ExxonMobil (50%).

A joint venture-owned/Shell-operated Sevan 400 FPSO has been selected as the development option for the field. Oil will be transported via tanker to refineries and gas will be transported via the FLAGS pipeline to the St Fergus gas terminal.

News Zohr Onstream Eni has produced first gas from the Zohr field offshore Egypt in the Mediterranean Sea, less than two and a half years since its discovery.

Located in the Shorouk block about 190km (118 mi) north of Port Said, the deepwater Zohr field has potential resources of more than 30 tcf of gas in place (about 5.5 Bboe).

Zohr is the largest gas discovery ever made in Egypt and in the Mediterranean Sea, according to Eni, and will be able to satisfy a part of the country’s natural gas demand for decades.

Eni holds a 60% stake in Shorouk block, along with Rosneft (30%) and BP (10%). The company is co-operator of the project through Petrobel, jointly held by Eni and the state corporation Egyptian General Petroleum on behalf of Petroshorouk, jointly held by Eni and the state company Egyptian Natural Gas holding Co. The story of Zohr dates back to 2012, when the field's 15 exploration areas came up for tender. Perforating offshore oil wells in the Mediterranean Sea had never produced good results in the past, but when a new opportunity arose, Eni had to decide quickly whether to bid for the tender.

Monitoring revealed that a reservoir was concealed in Block 9. In August 2015, Zohr turned out to be a good discovery.

The field is flowing 350 MMcf/d and is slated to produce 1 Bcf/d by the middle of next year, Egypt’s petroleum ministry said.

The project’s first phase includes six subsea wells, with gas transported 180km to an onshore plant at Port Said for processing and use in Egypt’s national grid. The second phase will comprise 14 more wells to be drilled by the end of 2019. The field sits in 1500m of water.

UTEC Contract

Last September, Baker Hughes was awarded a contract for Zohr’s Phase 2 subsea production system. The GE company will provide project management, engineering procurement, fabrication, construction, testing, and transportation, including seven manifolds, tie-in systems, long offset subsea and topside control systems, SemStar5 high-integrity pressureprotection systems, and workover systems and tools. The service company also will support installation, commissioning, and startup operations.

UTEC will provide subsea service support to Saipem for Zohr. The contractor will perform surface positioning on-board the Saipem-operated barges, Bautino and Castoro 10, and associated anchor handling vehicles.

In July, Saipem was contracted to provide engineering, procurement, construction, and installation (EPCI) work as part of the project’s “optimised ramp up” phase. The Italian contractor will install a 30in. outer diameter (OD) gas export pipeline, an 8in. OD service pipeline, and umbilicals, and provide EPCI work for field development of 4 wells. Work is expected to be completed by yearend 2018.

Eni attributes the rapid development of Zohr to the firm’s dual exploration model, adopted in 2013, which aims to generate cash during successful exploration by farming out interest in a project.

Statoil will acquire a 25% interest in the Roncador oil field in the Campos Basin in Brazil. The total consideration comprises an initial payment of US$2.35 billion, plus additional contingent payments of up to US$550 million.

The transaction nearly triples Statoil’s production in Brazil, with attractive break-evens and potential for additional value creation for

both parties through the application of Statoil’s expertise in improved oil recovery (IOR).

Roncador was the largest discovery offshore Brazil in the 1990s and is currently the third largest producing field in Petrobras’ portfolio with around 10 billion barrels of oil equivalent (boe) in place and an expected remaining recoverable volume of more than 1 billion boe. The ambition is to increase

the recovery factor by at least 5 percentage points, bringing the total remaining recoverable volumes to more than 1,500 million boe.

The field has been in production since 1999 with output, during November 2017, of around 240,000 barrels of oil per day plus around 40,000 boe per day of associated gas. The transaction increases Statoil’s equity production in Brazil by around 175% to around

110,000 boe per day from around 40,000 boe per day. Petrobras retains operatorship and a 75% interest.

In conjunction with the transaction, the two companies are entering into an agreement with the aim of maximising value creation and the longevity of the Roncador field.

Statoil will leverage its IOR technology, competence and experience from the

Norwegian Continental Shelf (NCS) and elsewhere, and Petrobras its experience as the largest deep-water operator and pre-salt developer in the world. Several specific opportunities for increased recovery and value creation have already been identified.

Petrobras and Statoil are partners in 13 areas in either the exploration or production phase, ten of which are located in Brazil and three abroad. The

acquisition will strengthen Statoil as one of the biggest oil producers in Brazil, operating the Peregrino field and block BM-C-33, both in the Campos Basin, and the BM-S-8 block in the Santos Basin.

Statoil has been deploying its IOR expertise across its global portfolio and has achieved an average recovery rate on the NCS well above the worldwide industry average-.

Ærfugl Aker BP (Aker BP) has, on behalf of the joint venture partners, submitted the Plan for Development and Operations (PDO) for Ærfugl to the Norwegian Ministry of Petroleum and Energy (MPE).

The Ærfugl field, including Snadd Outer, is a unique gas condensate field, nearly 60 km long and just 2-3 km wide, situated close to the Aker BP-operated Skarv FPSO, approximately 210 km west of Sandnessjøen.

The PDO covers the full-field development and includes the resources in both the Ærfugl and Snadd Outer fields which are planned to be developed in two phases.

The first phase includes three new production wells in the southern part of the field tied into the Skarv FPSO via a trace heated pipe-in-pipe flowline, in addition to the existing A-1 H well.

Production is planned to begin in late 2020.

The second phase is subject to further maturation, but the reference case includes two additional wells in the northern part of the field and one in Snadd Outer also tied into the Skarv FPSO with an estimated production start late 2023.

Other alternatives will be looked at to select the optimized concept.

The total remaining reserves for the full-field development are estimated at approximately 275 million barrels of oil equivalents.

Total investments in the Ærfugl project are estimated at NOK 8.5 billion (real terms) with NOK 4.5 billion in the first phase and NOK 4.0 billion in the second phase (reference case) respectively.

MEC-Combi Pipecrawler

New subsea inspection tool gets results five times faster Innospection has designed and developed a new subsea tool for inspecting caissons, which the company says, is five times faster than existing techniques.

The MEC-Combi Pipecrawler which is the first of its kind to use two types of subsea inspecting methods simultaneously for the external inspection of Caissons, to support ensuring their integrity.

14

The scanner collects both UT (Ultrasonic) and MEC (Magnetic Eddy Current) data, as well as close visual data and uses rotatable wheels in the design which pivot 90deg on its axis, so it can seamlessly overlap scans of the entire caisson circumference.

By collecting two different sets of inspection data within the same deployment it dramatically saves time and cost, requires little or no

cleaning, as well as providing more accurate than ever information about the assets condition.

Innospection have successfully completed the inspection of two caissons for an Operator in the North Sea using the new technology.

The Operator needed high density mapping data for the integrity assessment of the caissons and Innospection’s tool was able to provide it in record time.

Andreas Boenisch, Managing Director said: “Previously, many caisson inspecting techniques have only spot checked the circumference and therefore not fully shown the state of the caissons.

This technique shows in detail any localized corrosion and wall thickness to allow the operator to maintain caissons integrity to the highest standards.”

Teledyne TSS, a division of Teledyne Marine, announces the expansion of its leading range of subsea pipe and cable detection and tracking products with the launch of the new smaller HydroPACT 660 pipe tracking system.

The 660 has been designed to help reduce the cost of subsea pipe surveys by allowing the use of smaller classes of remotely operated vehicles (ROVs).

In addition, TSS is also expanding the capabilities of its larger HydroPACT 440 pipe tracking system by introducing a new 24VDC upgrade kit.

The new, compact HydroPACT 660 sports a single small form factor coil array measuring 1,200mm x 600mm at a weight of only 15.8kg that offers an operating range of greater than 85% of that of the significantly larger HydroPACT 440 system. This smaller and lighter coil array suits smaller ROVs such as observation class or inspection class.

Use of these smaller ROVs for pipe and cable surveys offers customers the opportunity to significantly

reduce their operating costs on future projects.

The HydroPACT 660 operates to 3,000m depth, and is offered with two different power options: 24VDC or 110VAC. The installation, operating routines and information displays are identical to those used on the 440 system, utilising the user-friendly, comprehensive DeepView operating software. The system comes with a choice of a vessel mounted PC or a rack mount computer.

Teledyne TSS has also launched a new 24VDC power supply pod for the HydroPACT 440 system. This is the first time that a 24VDC option for the 440 has been offered, and it will help to increase the flexibility and use of the system on vehicles that only support DC power capability.

This new power option is being offered in either 3000m or 6000m rated pods for both new 440 systems and as an upgrade kit for existing installations.

This offers customers the choice of either 110VAC, 230VAC and 24VDC options for their tracking system.

Vessels Wärtsilä will retrofit the world’s first energy storage solution on the North Sea Giant, one of the world’s largest and most advanced subsea construction vessels. The energy storage system will reduce the vessel’s energy consumption, operating costs and exhaust emissions, improving the operational efficiency and environmental footprint. The solution provides power redundancy and increases responsiveness of vessel operations.

Typically, a vessel with dynamic positioning uses two or more engines simultaneously to secure back-up power. This means that the engines’ load run low.

By using a hybrid/battery system to provide the needed back-up power, the operational engine can be used closer to its optimal load. In addition to the hybrid/ battery solution, the agreement signed in August 2017 includes transformers, filters, switchboard, shore connection equipment, upgrades of existing components and commissioning.

“For us is it important to reduce environmental emissions and modernise the vessel to make it more competitive," says CEO Hallvard Klepsvik, North Sea Shipping AS. "In addition, with a more efficient vessel, we will save fuel expenses.

"The estimated reduction in emissions is 5.5 million kg CO2, 30 tons of NOx and 1200 kg SOx per year. After Wärtsilä had retrofitted our ship Atlantic Guardian in 2014, we really understood how much fuel can be saved by improving the vessel’s efficiency. Efficiency also saves time, because you only need to refuel every second or third port visit”.

26

The North Sea Giant is a DP3 vessel.

Installation of an energy storage solution into a class DP3 vessel has never been carried out before and requires a redefinition of applicable classification rules.

Wärtsilä and North Sea Shipping AS are working in close collaboration with the DNV-GL classification society.

Statoil assumes Martin Linge and Garantiana Operatorships Statoil and Total have agreed on a transaction whereby Statoil will acquire Total’s equity stakes in the Martin Linge field (51%) and the Garantiana discovery (40%) on the Norwegian continental shelf (NCS).

Statoil will take over both operatorships and pay Total a consideration of USD 1.45 billion.

When in operation, Martin Linge will be a modern production facility with low production cost and low carbon footprint. As a result of the transaction, Statoil will also receive remaining tax balances with a nominal post-tax value of more than USD 1 billion.

Martin Linge is an oil and gas field under development west of the Oseberg field in the North Sea, with estimated recoverable resources in excess of 300 million barrels oil

equivalent. The expected production lifetime extends into the 2030s.

Martin Linge is being developed with a manned wellhead platform. The jacket substructure is already installed on location in the North Sea, while the topside is being completed at the Samsung yard in South-Korea and will be transported to Norway early 2018.

The project has experienced schedule delays and cost increases due to delayed topside engineering, construction and currency impact. A tragic accident at the yard in May 2017 also had consequences for the progress of the project.

The current operator expects start of production in the first half of 2019.

Recoverable resources have increased since the initial Plan for Development and Operation due to additional resources discovered.

Fulmar Such is the maturity of the North Sea, that any discovery would likely be not too far from an existing pipe or trunk line. This has enormous cost and time saving implications, bringing the development schedule of a field forward and allowing the prospect of earlier revenue.

In the early days of the North Sea, this was not so. Today, Fulmar is operated by Repsol Sinopec, and they bring the oil to shore, via the Norpipe, to Teeside. Back in 1978, however it was the fourth oil field in the North sea to achieve consent (after Hamilton's Argyll, Shell's Auk and BP's Buchan fields). No such pipeline infrastructure existed.

The development option selected by Shell was a loading buoy connected to a floating storage unit. A shuttle carrier was to be used to load the oil and take it to shore. The loading could take place in waves of less than 4.5m.

Shell selected a SALM Single Anchor Leg Mooring as the preferred, most cost effective option, taking into account, the rough seas and the relatively shallow 82m water depth.

Shell subcontracted the fabrication of the SALM to Rhine Scheldte Verolme in an ÂŁ8 million contract. The 1800t buoy had a diameter of 15m at its widest point although the buoyancy is part matched by the lower part is ballasted.

The jacket was lifted over the template

by Micoperi's Pearl Marine cranebarge and then, the Divy Beta drilled the remaining two wells.

By the time Shell's Auk came onstream, the company had begun to look at the next development on the list, Fulmar.

The development was based on a production platform weighing 12,600t.

Shell , however, decided on a novel development strategy.

Once Fulmar's main platform was installed, it would take a long time to drill the wells necessary to bring the field fully on stream. Shell decided to build and install a smaller wellhead platform to pre-drill the wells. By the time that the main platform and its production facilities were installed a year later, it could almost immediately start to achieve flow rates of 100 000b/d.

While the wellhead production jacket was being built at Methil by Redpath

Survey Kongsberg EM 304 Kongsberg has released the EM 304, the third generation of its industry standard 30 kHz Multibeam Echo Sounder System. It joins Kongsberg's range of Multibeam Echo Sounder Systems aimed at very shallow water to full ocean depth.

The EM 304 is used for high resolution seabed mapping from depths of 10m to beyond the continental rises – deeper than 8000m.

Developed as a low noise echo sounder with state-of-the-art electronics, the EM 304 delivers good data that requires minimal post-processing.

"The EM 304 is a highly scalable mapping system that takes advantage of features and benefits achieved in the development of the EM 2040 family and the EM 712," said a spokesman.

'In addition to offering increased range and resolution performance, the EM 304 introduces a broad range of functionality and cutting-edge new features that serve as a significant upgrade to the current generation EM 302 system.

"As part of a new EM technology platform designed for future challenges, the EM 304 is compatible with a new KONGSBERG developed datagram format, which supports several new features, such as extended backscatter calibration, with more features already in development."

The new format is supported by Kognifai, KONGSBERG’s open digital ecosystem which brings opportunities to transform survey operations through digitalisation.

KONGSBERG developed the EM 304

40 UT3 Issue 6 December 2017 January 2018

to utilise the same transducers as its current generation system, simplifying upgrading from the EM 302.

Installation is optimised thanks to a highly, modular and flexible system with compact electronics.

The EM 304 also accommodates easier installation through the use of a subbottom profiler. The KONGSBERG SBP 300 can be fully integrated, by sharing the same receiver transducer as the EM 304.

It is particularly suitable for use in operations in Arctic waters. The system can be delivered with ice windows for protection of the transducers, enabling light ice-class vessels to heavy ice breakers operating in the toughest ice conditions to enjoy the benefits of our new solution.

cNODEÂŽ MODEM EXPLORER

The cNODEÂŽ Modem Explorer is a transparent modem and positioning transponder for integration in your AUV. Supplied in a pressure rated housing or as screened board set, up to three remote transducers may be connected to suit different depths and horizontal offsets. Fully compatible with the latest generation HiPAP SSBL systems for extreme range, accuracy and reliability.

Deep BV takes delivery of Sonardyne Mini-Ranger 2 Positioning Equip

42

Deep BV, a Dutch survey company specialising in hydrography, marine geophysics and oceanography, has purchased underwater acoustic technology supplied by Sonardyne International, UK, to support its inshore, harbour, coastal and offshore activities.

The two Mini-Ranger 2 Ultra-Short BaseLine (USBL) tracking systems and WSM 6+ mini transponders were

delivered to Deep BV’s headquarters in Amsterdam within days of the order being placed and put straight to work during an operation to search for unexploded ordnance (UXO).

Mini-Ranger 2 boasts a number of features that makes it useful for underwater operations such as UXO surveys which require high accuracy positioning but without the cost and complexity associated with a deep water

UT3 Issue 6 December 2017 January 2018

USBL solution. It can simultaneously track 10 targets at very fast update rates, it is quick to install on small vessels and has a tracking range of 995 metres, extendable to 4,000 metres.

For its first project with Mini-Ranger 2, Deep BV installed one of the systems onboard their 15 metre, twin hull research vessel, Deep Volans, and configured it to track a WSM 6+

pment to support UXO surveys transponder mounted on a remotely operated towed vehicle (ROTV) named Iron Lady. Accurate positioning is paramount for the Iron Lady’s control software in order to ‘fly’ the six metrewide, gradiometer UXO set-up just two metres above the seabed.

Klaas Visser, Chief Technology Expert at Deep BV said, “We’ve been a user of Sonardyne’s pre-generation Scout USBL system for several years and

pleased with the results it’s delivered.

However, now was the right time to replace these systems and upgrade to Sonardyne’s 6G product family with all of its attractive features and performance gains.”

Speaking about the contract, Sonardyne Sales Manager, Alan MacDonald explained that Mini-Ranger 2 is ideally suited to the type of work carried out by Deep BV. “For example,

the transceiver that’s used to track transponders can be mounted alongside the multi-beam system in the moon pool of the Deep Volans.

"Then afterwards, it’s simple to move it to a different vessel. And thanks to its excellent noise rejection properties, the system’s optimised to provide reliable tracking in shallow water, near the surface where vehicles such as Iron Lady operate.”

AE1 Found

A search team armed with the latest multibeam echosounder systems, has discovered the whereabouts of the Australian submarine AE1. It disappeared without a trace on 14th September 1914 while patrolling waters off then German New Guinea.

This recently prompted an expedition will be led by the not-for-profitcompany Find AE1 Ltd and supported

by Fugro, the Australian National Maritime Museum and the Submarine Institute of Australia.

Underwater Vehicels SeaDrone ROV Mini-ROV manufacturer SeaDrone has launched its latest model, the Inspector 2. This upgraded model has an increased top speed and improved stability for better handling and more stable footage. It allows underwater inspection down to 100m.

"The ROV has new custom wound motors and improved driver firmware that ensure up to a 15% increase in efficiency at lower speeds," said SeaDrone CEO Eduardo Moreno "With its new and more stable control system and hydrodynamic tweaks, SeaDrone 2.0 is 20% faster than the previous version.

The original Drone Inspector was claimed to be the first sub-6 kg underwater vehicle capable of tackling stronger currents using its omnidirectional drag design and high thrust-to-weight ratio.

It consists of a 306mm (about 12in) diameter open drum-shaped body which houses the vectored thrusters.

This sits under a hemispherical dome that incorporates the buoyancy and control electronics. The ROV stands 270mm high.

SeaDrone front view

The SeaDrone frame is constructed from marine grade high-density polyethylene and dome is moulded from impact resistent polycarbonate.

"The circular design gives SeaDrone omnidirectional drag along the horizontal plain allowing it to fight cross currents, " said Moreno. "The Centre of Mass and the Centre of buoyancy are far apart designed which allows for increased stability.

48

"In order to achieve the optimum buoyancy, it is possible to quickly adjust up to 750 grams of stainless steel ballast weights to fit mission requirements.

thrusters and a single vertical thruster to move up the water column. These 175Watt thrusters allow the vehicle to achieve speed of 1.25 knots. They have a 2.5kgf maximum thrust force and a 2.3kgf reverse thrust. They can be driven at 300-3500 rev/min.

ROV Thruster The ROV is connected to the surface by a neutrally buoyant 4mm diameter tether, 30m to 250m in length. battery management system, and smart drivers insure stable performance and ability to diagnose any issue.

SeaDrone 2.0 batteries are located in the lowest part of the vehicle resulting in a stable platform that is easier to control and produces better footage.

These have a capacity of 5000mAh and an output of 25V. They have a batttery life of 3 hrs and a 1hr recharge time.

Tether SeaDrone’s auto depth and auto heading system is able to simplify the vehicle’s control using digital pressure sensor and 9-axis gyro and accelerator.

Automated vehicle stabilisation and integrated sensors allow for intuitive piloting. The thruster system automatically controls the propeller speed, monitors and feedbacks each thruster's current, voltage, RPM, and temperature.

The control system has three leak sensors, humidity sensor, batteries with

By using a magnetic keychain . it is possible to can wirelessly turn SeaDrone ON/OFF. Even Underwater!

At the front of the vehicle is a digital high compression HD camera featuring a 1/3in CMOS OV2710 sensor. This which allows video capture at 1080p ( 30 fps) in low-light conditions (0.05 lux) and allows expansion to a second camera.

It has a 150deg horizontal and 250deg vertical field of view.

SeaDrone dynamically regulates the camera's pitch angle to help reduce oscillations when piloting the robot and capturing footage.

There is an LED lighting array with an

SeaDrone control screen output of 5000 lumens.

It is possible to capture HD video and document inspection tasks with photos and audio notes stored and organized directly on a tablet interface.

"The Thrusters have no mechanical seals or pressure housing that will develop leaks," said Moreno.

"Repairing any thruster can take time and often exceeds the cost of the thruster. SeaDrone thrusters, therefore, have been designed to be easy and affordable to replace. Contd page 50

Subsea Equipment ROVCO

High Precision Repair

Subsea technology company, Rovco, has secured Innovate UK funding to develop a cutting-edge 3D visualisation system as part of a two-part Artificial Intelligence demonstrator project potentially worth ÂŁ1m.

The interconnector Skagerrak 2 between Kristiansand in Norway and Tjele in Denmark was damaged in end-July due to external impact. NKT was awarded the turnkey service repair order of the 250 kV mass impregnated (MI) high-voltage direct current (HVDC) offshore cable from the Norwegian system operator Statnett.

Working in partnership with the Offshore Renewable Energy (ORE) Catapult, the first phase of the project will see Rovco develop the equipment and software required to produce live 3D data from challenging and extreme subsea environments.

The technology will be trialled and tested at ORE Catapult’s renewable energy test facility in Blyth.

Phase two will include the development of a complete 3D vision-based survey solution using Artificial Intelligence (AI).

The technology could reduce offshore inspection costs by up to 80%, exploiting recent advances in both camera technology and embedded graphic processing, while utilising small, intelligent, autonomous robotic vehicles.

Once trialled and tested, Rovco believes the technology could revolutionise the way energy companies manage and inspect their subsea assets, potentially saving hundreds of millions of pounds in offshore inspection costs each year.

The first phase of the project will be 70% supported by Innovate UK, and the remaining 30% will be funded by Rovco.

The planned phase two is expected to be further backed by Innovate UK once technical feasibility is proven. This will see Rovco partner with an autonomous vehicle manufacturer and other innovative subsea companies.

personnel to remain outside the minefield. In peacetime, the AUVs contribute to hydrographic operations.

The ULS-500 PRO dynamic underwater laser scanner system will contribute to the detection, classification, and assessment of mines. 2G’s system acquires data in real-time and provides users with 3D models of targets and environments accurate to the subcentimetre.

The complete laser scanning system also includes the 2G Observer, an ultrasensitive stills camera able to capture images at 12fps, and the 2G Nova, an LED panel designed specifically for AUV integration providing almost 1,000,000 lumens.

Saab will demonstrate its anti-submarine warfare (ASW) training system, the AUV62AT, for the U.S. Navy (USN). The AUV62-AT is an artificial acoustic system that mimics a submarine.

The USN will evaluate Saab’s AUV62-AT against USN systems through the Foreign Comparative Testing (FCT) Program. The demonstration is planned for summer 2018, with an option to continue testing into 2019. The USN is investigating a replacement to its current ASW training system for its Undersea Warfare Training Range.

The AUV62-AT system is intended for ASW operator training, as well as for on board sonar, helicopter sonar and command system check-up. The system also plays an important part in the capability evaluation of an entire ASW force.

The AUV62-AT is an artificial acoustic target that mimics a submarine in a way that is compatible with any torpedo and sonar system on the market, today and in the future.

It system replaces the use of a submarine in the role of a manoeuvring training

target. The vehicle transmits broadband noise similar to the passive signatures of a conventional submarine. It also echoes back received active sonar pings received with a realistic target strength and echo elongation.

“With submarine usage on the rise, anti-submarine warfare training is more crucial than ever. Some of today’s submarines are armed with heavyweight torpedoes that can destroy a massive vessel rather than simply disable it.

AUV62-AT prepares operators for this threat,” says Görgen Johansson, Senior Vice President and head of Saab´s Business Area Dynamics.

Saab’s AUV62-AT package trains operators in submarine surveillance, detection, identification, classification, and target engagement.

The system fully replaces the use of a submarine in the role as a maneuvering training target and can be launched from a ship, a submarine, or shore.

The system is in service today with a number of countries worldwide.

Foundations Kriegers Flak wind farm leaves Ostend The barge with the two (10,000 tonnes and 8,000 tonnes) foundations, destined for the Danish offshore wind farm Kriegers Flak, has left the port of Ostend in Belgium – an important milestone of this project.

Depending on the weather conditions, the first foundation will be installed by the end of January, and the second a couple of weeks later.

Once the foundations have been installed our most recent multipurpose vessel AdhĂŠmar de Saint-Venant will start with the ballasting and scour protection works.

Jan De Nul Group and Smulders joined forces to build two Gravity Based Foundations (GBFs) for the high voltage station of the Danish offshore wind farm Kriegers Flak.

Both foundations consist of a concrete part (GBF) and a steel structure on top.

Jan De Nul Group was responsible for the design and construction of the concrete GBF, while Smulders tookk care of the design and construction of the steel shafts and decks placed on top.

The Danish wind farm Kriegers Flak, located in the Baltic Sea, will consist out of two parts. Kriegers Flak A, the west section, will have a total capacity of 200 MW. The east section, Kriegers Flak B, will have a total capacity of 400 MW. Each section will dispose of its own substation, serving both for the future Krieger Flaks offshore wind farm as well as an interconnector between the Danish and German power net.

By 2022, Denmark's to date largest offshore wind farm will start generating CO2-free electricity for approx. 600,000 households. The interconnector project is funded by the European Energy Programme for Recovery.

The vehicle is designed for use across several sectors, including law enforcement, research, environmental assessment, defence and infrastructure, and can search wide areas using AUV mode (untethered)

while conducting detailed inspections using ROV mode (tethered).

the demands of underwater exploration and inspection.”

Users can easily switch from AUV mode to ROV mode by attaching the tether to remotely control the vehicle’s six degrees of freedom of motion. When running the vehicle in autonomous operation, all mission planning is completed in an intuitive Windows-based application.
