Even though the historically low oil prices have led to a dip in traditional oil & gas activity, Tideway is optimistic that there will be somewhat of a recovery in 2017, though not back to the peaks of previous years. For now offshore wind is the busiest market and the company has already been awarded several key contracts for work in 2017 and 2018.
For Thorntonbank offshore wind farm in Belgium, Tideway worked on the replacement of an infield power cable. This included preparatory works removing the cable protection and power cable inside the jackets, recovering the defective cable, laying a replacement and burying the new cable.
In the UK, for the DONG Race Bank Offshore Wind Farm, Tideway assisted with the installation of the near shore export cables.
In Germany, the company carried out the postlay cable crossings for DolWin 3 and Veja Mate offshore wind farms. And at Nordsee One, Tideway completed the scour protection for the foundations.
Tideway performed rock dumping works at Godewind I and II and scour protection works were completed at the Galloper offshore wind farm.
In 2017, Tideway will be equally busy in the offshore wind sector with several awards. For Hornsea Project One in the UK, Tideway is responsible for the supply and installation of the power cable system. To optimise the trenching works a customised drag head is being engineered. This will reduce the volume to be removed and backfilled by the TSHD.
In the home market, several DEME subsidiaries – Dredging International, GeoSea and Tideway – will partner with each other at the Rentel offshore wind farm. They will execute the transport and installation of the 42 foundations, as well as the cable installation. Tideway will be responsible for the infield cable installation works, rock placement and erosion protection for the infield and export cables. Rentel is partly owned by DEME Concessions Wind.
This year Tideway will also carry out the infield cable installation works for the Merkur offshore wind farm, north of the islands of Borkum, Germany.
At DEME we are determined to challenge the forces of nature and tough project conditions.
We push through with thorough preparation and exceptional teamwork to find solutions for every difficulty encountered.”
In other challenging projects in 2016, Tideway performed rock placement works on the Lower Churchill Project for the Canadian power company Nalcor. This is for a huge hydropower project in Muskrat Falls, situated in Labrador in an extremely remote location. The company could only work in the spring and summer because of the harsh conditions. Three 30 km power cables were being placed to transport electricity through to Nova Scotia.
Tideway assisted with the execution of a landfall project in the south of Argentina, which was awarded to DEME. For this project, onshore and offshore trenching works were carried out and a 14” gas pipeline was pulled from a pipelaying barge to shore.
In the Strait of Gibraltar, Spain, Tideway successfully completed rock placement work for a pipeline stabilisation project for two major pipelines. This was carried out in spite of the high currents and in water depths of up to 400 m. Here the DP fallpipe vessel ‘Seahorse’ was deployed.
