Rigid Reel-Lay Pipe-in-Pipe Installed Off Malaysia

July 2014, Vol. 241, No. 7

A subsidiary of McDermott International, Inc. is the first to install rigid reel-lay pipe-in-pipe in Asia-Pacific for the Siakap North-Petai (SNP) development project offshore Malaysia. Located in more than 3,900 feet of water, 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 CEO, McDermott.

McDermott was awarded the full 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. Installation of the pipe-in-pipe production flowlines and rigid water injection flowlines was undertaken by McDermott’s Lay Vessel North Ocean 105, while flexible risers were installed by McDermott’s North Ocean 102.
