McDermott claims industry first in Asia-Pacific - installs rigid reel-lay pipe-in-pipeProjects and Operations // April 29, 2014
A subsidiary of McDermott International has become the first to install rigid reel-lay pipe-in-pipe in Asia-Pacific for the Siakap North-Petai (SNP) development project offshore Malaysia. At more than 3,900ft (1,190m), the SNP development is one of the industry’s most challenging deepwater projects.
“Successfully installing the rigid reeled pipe-in-pipe flowlines on the Siakap project is a significant achievement for McDermott and a first for the region,” said David Dickson, President and Chief Executive Officer, McDermott.
McDermott was awarded a turnkey contract in December 2011 for the project’s subsea infrastructure. This includes the design, procurement, fabrication and installation of two complex rigid insulated pipe-in-pipe production flowlines, one rigid water injection and one main umbilical system connecting eight new manifolds and subsea distribution units to existing riser slots.
As part of the pipe-in-pipe and water injection flowline system, McDermott combined its design capability from both its Houston and Singapore Subsea engineering offices, completed all spooling activities at its in-house regional spool base and fabricated the Pipeline End Termination (PLET) and In Line Tee (ILT) structures.
Installation of the pipe-in-pipe production flowlines and rigid water injection flowlines was undertaken by McDermott’s lay vessel North Ocean 105; flexible risers were installed by McDermott’s North Ocean 102.
