McDermott International, Inc. announces it will self-perform air and saturation diving on two key projects in the Americas, Europe and Africa region, which builds off McDermott’s vertically integrated model of project execution.
McDermott was awarded a sizeable* contract to remove and replace a single 24 inch (61 centimeters) 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 kilometers) 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.
McDermott’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 kilometers) off the east coast of Trinidad and Tobago. McDermott has an engineering, procurement, construction, installation and commissioning (EPCIC) contract from bpTT for the Angelin gas field.
McDermott 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 by McDermott on bare boat charter from Boskalis. McDermott diving operations include: free flooding the pipeline; barrier testing; metrology and 26-inch (66 centimeters) 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 dive 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 the third quarter of this year and expected to be installed in the fourth quarter.
“McDermott has a superb safety diving record with a strong reputation for delivery and outstanding results,” said Scott Munro, McDermott’s Vice President of Americas, Europe and Africa. “While we progress the project to upgrade the Amazon to support the ultradeepwater market with planned modifications to its pipelay system, the SAPREF project was a great opportunity to use the versatility of the Amazon and our diving teams to meet a critical need for the South African refinery. On the Angelin project, we are now getting ready for the next critical phase using our experienced divers and DLV 2000 crew to perform the installation work in this region.”
McDermott's diving function provides a variety of in-house underwater services in support of engineering, procurement, construction, installation and commissioning (EPCIC) execution projects such as pipe and cable lay, demolition and installation of spool pieces, risers, platforms and other structures. These operations are performed from McDermott's derrick barges, subsea construction vessels and DSV's.
Catering to both shallow and deepwater operations, McDermott maintains 12 mixed gas packages (MGP's), 5 saturation diving spreads and a large inventory of portable equipment. The MGP's are used for depths of up to 100 feet (30 meters) while the diving spreads can be used in depths of up to 984 feet (300 meters).
