Vessel Installs Suction Pile, Manifold, And Tree For Major Oil Company

Deep Marine Technology’s 292-foot DMT Emerald successfully installed a purpose built suction pile, subsea manifold, and tree for a major oil company utilizing its 100-ton multi-purpose tower.

The suction pile, over 35-feet-tall and 15 feet in diameter, was over-boarded in 4-6-foot seas and installed in under 12 hours.

The pile was landed at the desired location in 5,000 fsw and completed in 66% 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. The tree weighing 48 tons and measuring 15 x 15 x 20 feet tall was set via keel haul transferred to the 100-ton multi-purpose tower. It was set in 10 hours.
