Delta House Subsea Integration 

4150 FM 1069 Aransas Pass, TX 78336


LLOG Exploration is the 10th most active driller in the Gulf of Mexico and one of the top liquid producers in North America. With EXMAR technology, LLOG developed the Delta House oil platform. 

Delta House is a floating production system (FPS) with an oil export line, gas export line, and several subsea systems. The production system will eventually be located in Mississippi Canyon 254 and will accommodate the production of nearby fields with a handling capacity of 100,000 BOPD, 240 MMCF and 40,000 BWPD. 

The initial construction of the hull was built in Ulsan, South Korea and then transported to Kiewit Offshore Services in Ingleside, TX. The top side structures, which house all the equipment needed for production were fabricated and then integrated the top sides and living quarters on the hull at Kiewit Offshore.

Sea Level Marine was contracted by Kiewit Offshore in order to help with the subsea integration. This project included providing a side scan mapping survey in order to bring the rig to the location. 

In addition to the integration project, Kiewit contracted Sea Level Marine for the months of June, July and September 2013 for I-tube removal and installation flanges along the Delta House.
