Later followed by the Adhémar de Saint-Venant for the steering of the UTV1200, which then laid the cable in the seabed.TenneT had the steel jacket for the transformer platform placed on the seabed 50 km off the coast of Egmond aan Zee last August. The turbines of the wind farm will soon be connected to this socket. With the retraction of the last cable via the cable deck, the job is done for the contractor combination.Once the tests are

The remaining jacket sits in 141m water depth, making it a substantial

in 1971 that the Pan Ocean Group was awarded the production licence for the field in the second licensing round. The first well was drilled between July and December 1972 and proved to have both gas and condensate reserves. When it commenced production on 3 December 1985, Heimdal was the largest steel jacket on the Norwegian continental shelf. Production of gas and condensate proceeded at reasonably steady annual rates in the period from 1986 to 1996. Subsequent declining production led to plans to use Heimdal as an important transit and processing centre for gas from other fields. A riser
Huldra Platform Recycling Contract Awarded
Marine Contractors Nederland SE. The contract for disposal and recycling of the platform has been awarded to AF Offshore Decom AS, a subsidiary of AF Gruppen ASA The total weight of the platform is approximately 10,000 tons, distributed over a 5,000 ton topside and a 5,000 ton steel jacket. It is expected that more than 95 percent of the platform will be recycled. The plan is to remove the Huldra platform during 2019 with the subsequent disposal and recycling work taking place at AF Offshore Decom’s environmental base in Vats, Norway within the first half of 2020

venture with KBR won the contract for the complete delivery of the utility and living quarter (ULQ) topside. The platform also includes the advanced control room and the sental systems all installations on the field. In addition, Kvaerner is responsible for complete deliveries of three of the four steel jacket substructures for this phase of the Johan Sverdrup development. The main scope of the steel jackets will be constructed at Kvaerner's specialised facility in Verdal, Norway. For the complete delivery of the 19 000 tonnes topside, a large portion of the work will be executed at the company's

reduced total investment costs by around NOK 1 billion following the concept selection earlier this year. Maturing of the resource base, leading to higher volumes, has also helped realise the project. “The costs of subsea templates have tripled during the last 10 years. Platform wells on a steel jacket lead to considerable cost reductions and secure a robust project economy,” says senior vice president for the projects cluster in Statoil Torger Rød. Oseberg Vestflanken 2 is an important element in further developing the Oseberg infrastructure for the future, and is a result of

thoroughly for a long time making the preparations for this exciting and complex project. It feels great now that we’ve started construction on one of the biggest industrial projects in Europe,” says senior vice president for the Johan Sverdrup development project, Kjetel Digre. The steel jacket now being built at Kværner Verdal will weigh 26 500 tonnes, making it the biggest steel jacket in Europe. “The steel jacket will also be one of the most complex ever built by the industry. Not only will we route the land-based power through the jacket, we’ll also be controlling
