Subsea Loading Hose Exchange

Subsea Loading Hose Exchange

Bluestream was awarded a contract by Dana Petroleum the Netherlands B.V. for the change out of a 16” Subsea Loading Hose, connected to their Tanker Mooring & Loading System (TMLS) near the Hanze platform in block F2 of the North Sea Dutch Continental Shelf, in -42,0 Msw. Preparations for the project commenced in May 2014, with the engineering of installation procedures and the design for a deck carousel, over boarding chute, hose installation frames and other required installation equipment. All installation equipment, including a full surface supplied air-diving spread and ROV system, were mobilised on the DPII DSV Stril Server. After completion of the mobilisation of all equipment the new 114 meter long Subsea Loading Hose was pulled on deck in two sections, using the vessel crane and dedicated deck winches. Offshore the old Subsea Hose was removed from the TMLS and the new hose installed. The old hose was recovered to the deck of the DSV and transported back to shore.
The offshore scope of work was completed in July 2014. In addition to the Subsea Loading Hose Exchange, Bluestream also executed a significant part of the Dana Petroleum 2014 annual IRM program.
