Odfjell Drilling’s Deepsea Stavanger Semi-submersible contract for Semco Maritime, Norway Odfjell Drilling’s harsh environment drilling rig Deepsea Stavanger is undergoing a preparation and modifications contract at Semco Maritime’s Hanøytangen yard, on the outskirts of Bergen, prior to the start of its nine month drilling contract for Total offshore South Africa. The 2010-built semi-submersible heavy double derrick Deepsea Stavanger will complete a high docking (with thrusters on) during the first quarter of 2020. “The high docking enables for a minimised diving operation during antifouling of the hull and optimisation of the time spent on seawater valve change,” said Semco Maritime Norway’s managing director Lars Jønholt Halvorsen. The method furthermore enables for other measures to optimise the hydrodynamics of hull as the transit and planned drilling operation would benefit from this modification. The Deepsea Stavanger has been designed for operation in water depths up to 3,000 m The scope of the rig’s upgrade project includes upgrading of the hull and mooring system as well as the installation of purposebuilt equipment for operations in the harsh environment off the coast of South Africa. Denmark’s Maersk Supply Service (MSS) has been awarded an integrated FPSO tow and mooring installation project for an operator in the North Sea. The workscope includes project management, engineering and offshore execution involving six anchor handling tug supply and subsea support vessels. MSS will provide the full scope from site preparation, installation of pile anchors, tow of the FPSO, through to final hook up operations. This is the fourth large moorings project Maersk Supply Service is delivering following its announcement to expand and offer integrated solutions in November 2016, adding project management and engineering on top of its in-house fleet of more than 40 vessels and extensive experience as a marine service provider. “Last year we successfully carried out the tow and installation of the Ailsa FSO for the Culzean field. This was an important opportunity for us to showcase our capabilities in providing turnkey solutions to the market. The synergies gained from combining the role of vessel owner with project contractor to deliver our solution from one unified team exceeded our expectations and enabled us to meet demanding targets on scheduling, cost, and of course safety. We look forward to continuing to build on this track record within the UK sector,” says Head of Integrated Solutions, Olivier Trouve. Meanwhile, MSS has announced that it has implemented the ship management system Cloud Fleet Manager from German software provider Hanseaticsoft. MSS will be using the Cloud Crewing module of the web-based system for vessels and shore-bases to manage

their crews and handle all crew-related tasks.

Equinor’s Bay du Nord oil field to be compliant

DNV GL will ensure that new infrastructure to be built for Equinor’s Bay du Nord oil field project is compliant to local and global safety requirements. DNV GL will oversee design review activities and site surveillance during construction, commissioning and installation, after being awarded the Certifying Authority and Classification contract. The Bay du Nord field is located approximately 480 kms northeast of St. John’s, Newfoundland and Labrador, in the Flemish Pass Basin. The distance to shore is a challenge in itself, and the Bay du Nord is the first field to be developed in this basin. No existing infrastructure is in the immediate area, which is known for its harsh environmental conditions including large sea states, high winds, sea ice and icebergs. Bay du Nord is an oil field discovered in 2013, aiming to produce its first oil 2025. The Bay du Nord project is currently in Pre-FEED phase and Final Investment Decision is planned for the second quarter of 2021. The field development comprises a FPSO, a disconnectable turret and moorings system, steel lazy wave risers, and a subsea development with four subsea templates. Equinor is the operator of Bay du Nord, and holds a 65% working interest. Both Equinor and DNV GL will manage the project out of offices in St. Johns, Newfoundland and Labrador, Canada. Meanwhile, Northern Drilling’s West Mira is the first rig in operation to be awarded the DNV GL Battery (Power) class notation. West Mira is an ultra-deepwater semi-submersible designed by Norway’s Moss Maritime, operating a hybrid power plant using Lithium-ion batteries as spinning reserve in dynamic positioning (DP)

By incorporating batteries on-board, the ultra-deepwater semi-submersible West Mira can reduce the runtime of its diesel engines significantly

operations and to supply power during peak load times. Installation and testing of the energy storage system have been completed with close cooperation between Seadrill/Northern Drilling, Siemens, Kongsberg Maritime and DNV GL. By using the four converter-battery systems, the operator estimates it will be able to reduce the runtime of the rig’s on-platform diesel engines by 42%, cutting CO 2 emissions by 15% and NOx emissions by 12%. The system will also serve as back-up to prevent blackout situations and provide power to the thrusters in the unlikely event of loss of all running machinery on affected switchboard segments. The Battery class notation applies to Li-on batteries of >20 kW/hr installed on-board DNV GL classed vessels and offshore rigs and builds on DNV GL’s rules for the installation and use of Li-on batteries. DNV GL has also updated its rules for dynamic positioning to include batteries as a “spinning reserve”, a redundant power source for dynamically positioned vessels designed to fulfil IMO equipment Class 2 or 3 for vessels with DP systems.

Huisman wins Boskalis contract

Rotterdam’s Huisman has won a contract from Holland’s Royal Boskalis Westminster to deliver a 4,000 tonnes Offshore Mast Crane (OMC) to be installed on its new crane vessel Bokalift 2. This contract follows the delivery of the 3,000 tonne OMC for the Bokalift 1 in 2017. With a lifting capacity of 4,000 tonnes at 100 m above deck, this crane is capable of lifting jackets for wind turbines off the deck of the vessel. A fly jib allows lifting of smaller components up to a height of 125 m above deck. The configuration of the hoisting tackles is such that the crane is capable of lifting large jackets and of upending long (mono) piles from a horizontal to vertical position. The crane is outfitted with a carefully selected number of auxiliary systems, aimed specifically at installing tall structures while the vessel is subject to wave induced motions. The launching project for the crane vessel will be the installation of jackets for the Taiwanese Changfang and Xidao offshore wind farm project, which was awarded to Boskalis recently. The particular characteristics of the Huisman mastcrane have proven to be advantageous for offshore construction vessels. These cranes have a small footprint and no tailswing, which leaves maximum space on the deck of the vessel for payload. With its ability to lift structures more than 100 m high Huisman’s OMC will make the Bokalift 2 a flexible value adding asset, well positioned for the installation of current and future generation offshore wind turbine foundations. Also, it is well-positioned for work in the offshore oil and gas, decommissioning and salvage industries.

FPU contract for Sembcorp Marine

Singapore’s Sembcorp Marine Rigs & Floaters has won a contract from Shell Offshore to build and integrate the topside and hull of a Floating Production Unit (FPU) for the Whale field in the Gulf of Mexico. The agreement precedes a final investment decision for the full Whale project, expected to be made next year by Shell. It paves the way for the Whale FPU to move ahead and take advantage of synergies from the on-going Shell Vito FPU, currently under construction at Sembcorp Marine’s Tuas Boulevard Yard. The Whale FPU comprises a topside module and a four-column semi-submersible floating hull, with a combined weight of 25,000 tonnes. Slated for completion in 2022, it will operate in the Alaminos Canyon Block 772. “We are very grateful to Shell for recognising our yard capabilities and entrusting us with the Whale FPU project, which comes after our successful bid for the Shell Vito FPU last year,” Sembcorp Marine Head of Rigs & Floaters William Gu said. Like the Vito FPU, the entire Whale FPU topside will be integrated and commissioned on ground level at Tuas Boulevard Yard in order to minimise work-at-height risks for the workers. The completed FPU topside will then be raised and attached to a 51-m tall hull, using a pair of gantry cranes that can lift up to 30,000 tonnes. “With our state-of-the-art 30,000-tonne cranes at Tuas Boulevard Yard, we can assemble the Whale FPU topside into a megablock and combine it with the hull efficiently in one single lift,” Mr Gu said, adding that the yard’s enormous lifting capacity is becoming a winning differentiator for Sembcorp Marine’s project execution. Other than the Whale and Vito FPUs, Sembcorp Marine’s project track record in the Gulf of Mexico includes previous deliveries of eight semi-submersible drilling rigs and one semi-submersible hull. Meanwhile, Sembcorp Marine has delivered the Q7000 well intervention semi-submersible rig to Helix Energy Solutions Group, following a fruitful collaboration between the two companies to complete the project amid challenging market conditions. Measuring 93.6 m in length and 61.1 m in breadth, the Q7000 was jointly designed by Sembcorp Marine and Helix. The vessel can perform a wide range of production enhancement operations as well as field development support, well clean-up and well decommissioning tasks such as tubing removal and sea floor clearance.

KM continues collaboration with Golden Energy Offshore

Norway’s Golden Energy Offshore has reported that its long-term collaboration on vessel performance monitoring with Kongsberg Maritime and deployment of the containerised SAVe Energy battery system earlier this year is delivering operational fuel savings of 20%. The results have been achieved on Golden Energy Offshore’s UT 776 CD design Platform Supply Vessels (PSV), NS Orla and NS Frayja. Already operating efficiently with extensive Full Picture technology packages on-board, Golden Energy Offshore and Kongsberg Maritime have been monitoring and analysing data from the ships since 2015. Monitoring is provided by the Kongsberg Vessel Performance System (VPS) – with the new vessel data to cloud infrastructure Vessel Insight also deployed this year – enabling Golden Energy Offshore to gain deep insight and transform daily vessel operations to achieve significant fuel reductions. The VPS is integral to Golden Energy Offshore’s commitment to the UN Sustainability Goals, with focus on Industry, Innovation & Infrastructure, Responsible Consumption & Production, Climate Action, Life Below Water and Partnership for the Goals. Kongsberg Maritime’s data analytics team also found a significant potential for further savings by introducing battery power and in line with its strategy of taking knowledge based steps towards greener operations, Golden Energy Offshore selected the Kongsberg SAVe Energy battery system, which was installed on both ships in 2019. The operational data already collected informed key installation factors including the size of the batteries to be deployed for optimal operations. Both vessels have now been sailing with batteries for more than six months, returning significant operational cost reductions. Kongsberg Maritime’s SAVe Energy concept is an Energy Storage Unit that includes a highly efficient and liquid cooled battery system in a modular design. The system is scalable according to energy and power requirements, complies with international legislations for low and zero emission propulsion systems, and can be used for peak shaving, spinning reserve and for full battery power for offshore vessels, cruise ships, ferries, tugs and workboats. The Kongsberg VPS enables informed decision making by both crew and onshore teams, with the potential to assist customers in lowering energy usage, fuel consumption and operating costs. It provides details on fuel consumption and overall energy efficiency levels, benchmarked against historical performance, allowing the crew and ship management to exploit opportunities to minimise fuel usage and reduce emissions. Following the co-operation with Golden Energy and other customers, the Kongsberg VPS has now been further developed to also cover battery performance monitoring. SORJ
