McDermott International Inc. has announced that it will self-perform air and saturation diving on two key projects in the Americas, Europe and Africa region, which builds off its vertically integrated model of project execution.

The company was awarded a sizeable contract to remove and replace a single 24 in. (61 cm) subsea hose string to a single buoy mooring (SBM) and pipeline end manifold (PLEM) for Southern Africa’s largest crude oil refinery operated by SAPREF, located about 1.5 miles (2.5 km) off the coast of Durban, South Africa.

McDermott will conduct a scheduled critical saturation and air diving campaign in early May from the multi-purpose vessel, Amazon, which will function as a diving support vessel for the project. The project marks an operational return to Africa for McDermott.

The company’s global diving team will also support the pipeline installation and pre-commissioning work for the BP Trinidad & Tobago, LLC (bpTT) Angelin project, located 25 miles (40 km) off the east coast of Trinidad and Tobago.

It will use a mix of McDermott divers and local Trinidadian divers to perform the diving activities. The divers will work off the diving support vessel (DSV) Da Vinci, contracted on bare boat charter from Boskalis. McDermott diving operations include: free flooding the pipeline; barrier testing; metrology and 26 in. (66 cm) spool tie-in at the new platform and at the Serette facility; pre-commissioning support for pigging, hydrotesting and de-watering of the pipeline and free span rectification. The team will use the DSV with support from local Trinidadians for the planned month-long campaign. McDermott's DLV 2000 will install the platform and pipeline, which is due to arrive in Trinidad in 3Q18 and expected to be installed in 4Q18.
