DMT Emerald

HOUSTON — Deep Marine Technology’s 292-foot vessel DMT Emerald has installed a purpose built suction pile, subsea manifold, and tree for ExxonMobil at the Rockefeller field on East Breaks Block 992 in the Gulf of Mexico.

The suction pile, which is over 35 feet (10.6 m) tall and 15 feet (4.6 m) in diameter, was successfully over boarded in four-foot (1.2-m) to six-foot (1.8-m) seas and installed in under 12 hours. The pile was landed at the desired location in 5,000 feet (1,524 m) of water, and completed in 66 percent of the allotted time given by the client.

The DMT Emerald crew additionally installed a manifold and set a tree.  The manifold weighing over 35 tons was successfully installed onto the suction pile ahead of schedule and without any issues.  The 48-ton, 15-foot by 15-foot by 20-foot (4.6-m by 4.6-m by 6.1-m) tree was set via keel haul transferred to the 100T multi-purpose tower. It was set in around 10 hours.

The DMT Emerald includes the 100T multi-purpose tower, a 100T knuckle boom Crane, a 23-foot by 27-foot (7-m by 8.2-m) moon pool, accommodations for 73, and two Triton XLS work class remotely operated vehicles.
