KerrMcGee_Boomvang Nansen

U.S., Gulf of Mexico Blocks EB 642, 643, 688 and 601, 602, 646

Landmark: World’s first truss spar

Nansen, located in 3,770 ft (1,150 m) of water, was developed using the world’s first truss spar, which enhances performance while reducing size and cost. The truss spar is a new version of the original Neptune production spar from 1996.

First production was announced in January 2002, less than two years after development was sanctioned. Nansen was developed simultaneously with Boomvang, which set an industry standard for the deepwater Gulf of Mexico. Boomvang, located in 3,450 ft (1,050 m) of water about 9 miles (15 km) from Nansen, also is being developed using a truss spar and came onstream during the second quarter of 2002.

Boomvang Nansen was the world’s first horizontal tree system to have utilized a tubing hanger that houses both the upper and lower crown plugs, eliminating the need for an internal tree cap.
