Equinor and its partners Petoro, TotalEnergies, Shell and ConocoPhillips in the Troll and Oseberg fields, have initiated a study and are looking into possible options for building a floating offshore wind farm in the Troll area some 65 kilometres west of Bergen, Norway.

With an installed capacity of about ~1 GW and an annual production of ~4.3 TWh, with a startup in 2027, Trollvind could provide much of the electricity needed to run the offshore fields Troll and Oseberg through an onshore connection point. The Bergen area already serves several of these installations with power – and needs more input to its electricity grid. The plan is that the partnership will buy as much energy as the wind farm can produce at a price that can make the project possible.

Power from Trollvind could make a solid contribution towards electrification of oil and gas installations, accelerate offshore wind development in Norway, and deliver extra power to the Bergen region.

“By producing oil and gas with low greenhouse gas emissions, we reinforce the competitiveness of the Norwegian shelf, maintain activity in the industry and safeguard future value creation. Trollvind is a concept where renewable energy works to facilitate several objectives; helping cut emissions through electrification, delivering power to an area where shortages have already created challenges for new industrial development, and Norway maintains its position as a leader in the industrialisation of floating offshore wind. A full-scale floating offshore wind farm like Trollvind could boost momentum towards realising the Norwegian authorities’ ambition to position Norway as an offshore wind nation, building on expertise from the oil and gas industry,” says Equinor’s chief executive, Anders Opedal.

In 2020, the Norwegian parliament (Stortinget) decided to intensify emission reductions requirements from the Norwegian continental shelf from 40 to 50 per cent by 2030. To achieve this target, large-scale industrial single-point emission sources, such as offshore oil and gas installations, must reduce their emissions. Electrification of installations with long remaining lifetimes will be a key initiative to succeed with this transition.

“This initiative provides the supplier industry with predictability and an offshore wind portfolio to work with in the years ahead,” Opedal adds.

“This can be a fantastic opportunity for Norway and for the industry,” said Shell’s global EVP, Renewable Generation, Thomas Brostrøm.

“Using our integrated capabilities to decarbonise existing operations and accelerate offshore wind development is exactly the kind of action our companies need to be taking to further society’s progress towards net zero by 2050”.

“We are excited about the possibilities to supply our energy production offshore with new renewable power. This project confirms Norway’s leadership in green energy production and our experience that working together is a value enabler,” says Phil Cunningham, TotalEnergies Managing Director and Country Chair.

“In this study, we build on our Norwegian competitive edge and strengths: Technology development and collaboration. The cooperation between all parties is crucial to realize the transformation of the industry to a low-carbon future. This is important for Norway as a mature oil and gas region and will ensure a competitive Norwegian shelf also in the future,” says Kristin F. Kragseth, Petoro’s CEO.

Trollvind can be realised by building on the good collaboration established between government authorities and the industry through Hywind Tampen. Experience can be transferred and learning utilised while at the same time identifying and implementing good co-existence solutions from an early stage.

By transferring offshore wind power to shore this may enable the possibility to build a larger wind farm than one directly connected to oil and gas installations offshore. Increasing the size of wind farms is a key factor in industrialising floating offshore wind and reducing costs. Bringing the power to shore also promotes more efficient power utilisation through better interaction with regulated hydropower and onshore industry. Increased access to power in this area also means improved security of supply for the oil and gas installations.

The partners are evaluating commercial arrangements where the Trollvind development are selling power to the Troll and Oseberg installations and the Kollsnes plant. Trollvind will not require other forms of financial support. Estimates indicate that Trollvind can deliver power for less than NOK 1/kWh. Such an agreement would ensure greater long-term access to power at a stable price in an area where the power situation is strained. At the same time secure a sufficient income level for the wind farm to trigger the investment.

Trollvind is now being further matured by the Troll and Oseberg partners initiating feasibility studies aimed at an investment decision during 2023.

Damen Shipyards delivered a complete equipment package for the multipurpose vessel ENDAM. Owned by the Korean Marine Environment Management Corporation, the newbuild combines emergency oil spill recovery activities with maintenance dredging tasks.

With a 4,100 m3 hopper hold, the vessel was built by HJ Shipbuilding & Construction at its Busan yard and designed by KmsEmec. The mission equipment package provided by the Damen Technical Cooperation team included a 15 m rigid oil sweep arm with a dedicated pump and handling crane for the emergency oil spill recovery functionality, and a complete turnkey dredging system, which was designed specifically for the vessel.

Turnkey dredge package

The turnkey dredge package consisted of both loading and discharging equipment, a hydraulic system, dredging control system and various drives. A 900 mm trailing suction pipe, designed to dredge at a maximum depth of -30m, is hoisted by three dedicated gantries and their hydraulically operated winches. All the trailing suction pipe components are located starboard aft.

A Damen dredge pump, type BP9075HD, completed the dredge pipe arrangements. The highly efficient slurry pump is designed for both suction dredging, as well as discharging over the bow using the bow coupling unit or rainbow nozzle. This hopper discharging equipment, including 12 bottom dump valves which Damen designed, were all part of the dredge package. Furthermore, dredge valves in various pressure stages were delivered for the suction and discharge piping. Dedicated dredging instrumentation completed the package. This is crucial to monitor and visualise the dredging process and to optimise the dredging operations.

Component integration

Due to the DTC team’s extensive experience in component integration at non-Damen yards, the large system parts were delivered from the Netherlands and integrated effortlessly. As well as the mission equipment, the delivery scope included a hydraulic system. This is a logical choice as the dredging equipment is its main user. Additionally, a 3,500-kW electric dredge pump drive and a 1,000-kW electric jet water pump drive were shipped to Korea. The delivery was completed with a full set of spares and Damen also carried out the commissioning and training on board.

The vessel was named ENDAM, which means ‘the fence that protects you’ in the Korean Jeju dialect. A festive handover ceremony took place in the summer and ENDAM has successfully started operating along the Korean coast.
