MCDERMOTT International derrick lay vessel DLV 200 will start subsea construction support work on the INPEX operated Ichthys LNG project offshore Western Australia in May.

The vessel, launched in a naming ceremony at the Keppel Singmarine Shipyard in April, will work at the Ichthys project for several months as part of McDermott’s work program for the project.

The DLV 2000 is expected to join the project as part of McDermott’s 2016 current project schedule by installing large subsea spools, laying infield umbilicals and lifting several subsea distribution units that will provide the hydraulic, chemical and electrical distribution from the umbilicals to the subsea drill centres.

McDermott president David Dickson said by using the DLV 2000 on a project that would normally require multiple vessels with a combination of pipelay and heavy lift experience, project proponents would benefit from a more efficient operation.

“Through the long established relationship between Keppel and McDermott, the DLV 2000 has been built to a world class specification and on budget,” he said.

“The vessel represents a strategic component of McDermott’s long term plan to deliver the best in class projects to our global customer base.”

Additionally, the DLV 2000 is scheduled to support the transportation and installation contract awarded by Woodside Energy Limited for the Greater Western Flank Phase 2 subsea pipeline and installation project in Western Australia.

The DLV 2000 is a class 3 dynamically positioned vessel combining a 2,200 tonme revolving crane with a deepwater under deck S-lay pipelay system configured to install pipelines with diameters ranging from 4.5 to 60 inches in water depths up to 10,000 feet.

The vessel can accommodate up to 400 personnel to facilitate large hook-up and commissioning projects, has a fast transit speed and incorporates a large, 43,000 square foot open deck to allow the transportation and assembly of large subsea structures; enabling safe and efficient stand-alone operations in remote areas.

Work is scheduled to be performed in conjunction with McDermott’s other new subsea installation vessel, the Construction Support Vessel 108 (CSV 108), which is working successfully on the project.

The CSV 108 is expected to undergo an upgrade later in 2016 to install a vertical lay system and reel deployment system for use on the project and will then be referred to as the Lay Vessel 108 (LV 108), McDermott said.
