"We opened the facility because we supply a lot of umbilicals to this region, particularly in the diving and decommissioning sectors," said Umbilicals International UK General Manager, Charlie Backhouse. "This facility will help us provide a more efficient service to our nearby customers.”

Supporting Diving Operations Mr Backhouse continued, “Initially, our main products will be excursion umbilicals for main diving bells, but we will also support oil and gas decommissioning, as well as the seismic sector. In addition to this, as the energy market picks up, we will look to supply umbilicals for subsea jumpers, topside jumpers and IWOCS. We are mainly focused on thermoplastic umbilicals and thermoplastic hoses, however, we could easily manufacture short lengths of super duplex jumpers and flying leads.

“The umbilicals that we will supply to the decommissioning market will be mainly for subsea cutting, such as wellhead cutting and for tubing-casing cutting. We could also manufacture electrohydraulic umbilicals for any form of shallow water tooling and intervention tooling. We have supplied umbilicals for abrasive fluids and for laser 16 cutting. 17

UT3 Issue 3 July 2018 UT3 Issue 3 July 2018 Borkum II and Borkum Riffgrund II cable installation

Jan De Nul Group successfully completed the export cable installation works in the German North Sea in order to connect the offshore wind farms Trianel Windpark Borkum II, developed by Trianel, and Borkum Riffgrund II, developed by Ørsted, to Tennet’s German transmission grid.

For both cable installation projects, Jan De Nul Group’s cable laying vessel Willem de Vlamingh and trenching support vessel Adhémar de Saint-Venant were mobilised.

In the summer of 2017, Willem de Vlamingh identified and removed potential UXOs from the cable routes. In the spring of 2018, she sailed to the cable load out facilities in Greece to load the three cables with a total length of 26.4 km. Willem de Vlamingh successfully completed the installation of all three cables on 25 April 2018.

The first two cables connect the Borkum Riffgrund II wind farm substation with the Dolwin Gamma convertor station. The third cable connects the Trianel Windpark Borkum II with the Dolwin Alpha convertor station. These Dolwin platforms convert the electricity generated by the two wind farms into Direct Current (DC) before transporting it to Tennet’s onshore network.

The trenching support vessel Adhémar de Saint-Venant executed the cable protection works by means of post-lay jet trenching using Jan De Nul Group’s UTV1200 trencher. Trenching was completed on 16 May 2018.

The Greek cable manufacturer Hellenic Cable is currently terminating and testing the cable connections. Overall 24commissioning is planned in June/ 25 July 2018

Installing the Johan Sverdrup Drilling Platform Topsides In early June, Equinor's Johan Sverdrup 22 000t drilling platform topside was lifted into position in one single lift onto the jacket. This was the first time that this technology had been used for topsides installation.

The Johan Sverdrup drilling topside was assembled at the Aibel yard in Haugesund. To maximise the amount of work carried out onshore, it was 85% fully tested before being taken offshore for installation.

Aibel won the contract for the Johan Sverdrup drilling topside in February 2015. The contract, worth NOK eight billion, was one of the biggest individual contracts awarded during Phase 1 of the field development.

The largest module, the main deck, was built at Aibel’s yard in Thailand. The drilling support module, the second largest unit, was built in Haugesund. The third module, the derrick and associated equipment, was built by Nymo in Grimstad.

The three modules were assembled in Klosterfjorden in early September 2017. The topside was then towed in to Aibel’s yard in Haugesund. The previous nine months were spent carrying out hook-up 42 and fabrication activities . 43 (Photo: Bo B. Randulff / Equinor)
