McDermott divers at work offshore South Africa, Trinidad & Tobago
McDermott International will perform air and saturation diving on two projects offshore South Africa and Trinidad & Tobago.
HOUSTON – McDermott International will perform air and saturation diving on two projects offshore South Africa and Trinidad & Tobago.
SAPREF has contracted the company to remove and replace a 24-in. subsea hose string to a single buoy mooring and pipeline end manifold (PLEM) associated with an oil refinery 1.5 mi (2.5 km) offshore Durban.
This will involve saturation and air diving in early May from the multi-purpose vessel,Amazon, which will function as a diving support vessel for the campaign.
McDermott’s diving team will also support pipeline installation and pre-commissioning work for the BP Trinidad & Tobago-operatedAngelin project, 25 mi (40 km) off the east coast of Trinidad & Tobago.
The company has an EPCIC contract from BP for this project.
McDermott will use its own and local Trinidadian divers working from the DSVDa Vinci, which the company has contracted on a bare boat charter from Boskalis.
Operations will include free-flooding the pipeline; barrier testing; metrology and a 26-in. spool tie-in at the new platform and at the Serette facility; pre-commissioning support for pigging; hydro-testing and de-watering of the pipeline; and free-span rectification.
McDermott’sDLV 2000 will install the platform and pipeline, which is due to arrive in Trinidad this summer.
