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 industryâ€™s most challenging deepwater projects.
â€œSuccessfully installing the rigid reeled pipe-in-pipe flowlines on the Siakap project is a significant achievement for McDermott and a first for the region,â€ said David Dickson, president and CEO, McDermott.
McDermott was awarded the full turnkey contract in December 2011 for the projectâ€™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 McDermottâ€™s Lay Vessel North Ocean 105, while flexible risers were installed by McDermottâ€™s North Ocean 102.
