A (Nansen Spar)

The Nansen Spar facility, operated by Anadarko (which has 50 percent ownership), has been in operation since 2002. It is also 50 percent owned by Ocean Energy Inc. The Nansen deepwater oil and gas field is located south of Galveston, Texas, in the Gulf of Mexico. Water depths in the area are up to 3,675 feet, and the structure is in East Breaks Block 602 and 646. The discovery well at the site was originally drilled in September 1999.

Nansen is one of 10 floating oil platforms run by the company. In 2008, production was stopped to make repairs following Hurricane Ike, as with other rigs in the area. The facility underwent a two-to-three-week completion and workover program in 2009.

Additional Site History

Production from the first of three subsea wells began in 2002. By Q4 of that year, the Nansen field was producing 40,000 barrels of oil per day and 80 million cubic feet of gas. The facility had the first open truss design for an oil platform in the world, adding stability and, with the aid of air chambers in the upper hull, buoyancy.


A Bureau of Safety and Environmental Enforcement (BSEE) report detailed a March 2015 incident in which an injured worker required medical evacuation. Contract workers were replacing corroded stud bolts from a production header flange; the person injured was struck in the face by part of a pneumatic tool that slipped. The incident resulted in a laceration to the right side of his mouth, dental trauma, and a possible maxilla fracture, according to the report. An onsite investigation determined the contractor and lessee did not use the best available/safest technology, citing potential factors that were known to lead to such accidents with the tool.

In 2016, the total number of offshore injuries in the Gulf of Mexico was 151, the lowest over a 7-year reporting period, based on BSEE statistics. There were 206 worker injuries reported in 2015.
