Lewek Constellation 




EMAS AMC’s subsea construction vessel, the Lewek Constellation, established an industry record for pipelay in the U.S. Gulf of Mexico (GoM) in 7,368ft (2246m) of water during her sea trials.

Scope of work:

In preparation for the execution of three subsea tie-back projects for Noble Energy, the Constellation performed her final pipelay trial in the GoM. During the deployment of the 3.2km, 16in diameter, 28mm wall thickness pipeline, complete with the second end pipeline end termination (PLET), the tension recorded was 632mT, rendering this the highest tension ever experienced in the history of rigid reeled-lay operations. The Lewek Constellation is home to HD ROVs #08 & 16, manufactured by FMC Technologies Schilling Robotics, that handle the construction tasks for ROV projects.

“Successfully laying the test pipe at this record-breaking top tension during pipelay trials is a significant achievement for EMAS and an industry first,” said Lionel Lee, chairman, EMAS AMC. "It's a testament to the experience and expertise of our people combined with the quality of our new vessel built by EMAS Group’s subsidiary TRIYARDS in Vietnam.”

“What this record means for clients going forward is that we can offer a more efficient pipelay solution in ultra-deepwater for pipelines up to 16in in diameter when compared to traditional S-Lay or J-Lay methods, even with thick insulation coatings, thereby giving our clients more options to consider,” said John Meenaghan vice president global operations.
