Genesis Spar

The Genesis Spar is located in an oil field in the Gulf of Mexico, about 150 miles to the south of New Orleans. It is located in the area called Green Canyon, in blocks 160, 161 and 205 and is part of the Viosca Knoll Carbonate Trend. Here the water is somewhere between 2,500 to 3,000 feet deep, and the platform is moored in 2,600 feet of water.

The spar was engineered in two phases. The first phase included front-end engineering to prepare detailed installation plans, electrical requirements, equipment needs and expenditures. The second phase detailed the engineering of the structure including designs for all of the electrical, instruments and hook up information necessary to proceed with the installation.

The spar utilizes cylindrical steel to support the entire facility including both drilling and production, the first of its kind in use. The upper portion provides areas that are filled with air to allow for buoyancy, and at the same time, the tanks at the bottom are filled with water to weigh the unit down and stabilize it.

The platform was produced by McDermott at their facility in Louisiana with engineering completed by their Houston team. The deck surface has three levels that are each 175 feet by 175 feet in size for a total of about 100,000 square feet. The platform weighs about 9,000 tons. The topside utilized 5,150 tons of structural steel and 2,600 tons of equipment with 945 tons of pipes, lines, and instruments.

The hull was crafted in two parts and was made at the Aker Rauma Pori yard located in Finland. One section weighed 10,842 tons, and the other weighed 15,861 tons. The total size of the hull is 122 feet in diameter and 705 feet high. Installation was done in several parts including the mooring, hull, and topsides. There is a 14-point mooring system to anchor the platform in place. Each mooring pile has a diameter of 8 feet and is 235 feet in length. The hull was installed in a staged free-flooding method to place it atop and rotate it into place. It was attached to the mooring lines using a temporary work deck.

The spar can support up to 20 production risers, two export risers, and a drilling riser. There are 20 subsea wellheads that are arranged in a circular pattern forming a 140-foot circle.  The large oil platform cost about $800 million to complete and is owned by Chevron.

Accident Report

In 2015 a worker was killed in an incident that occurred on a Chevron-owned oil rig in the Gulf of Mexico. There were no other injuries and no reported pollution as a result of the incident. This isn’t the first accident on Chevron offshore oil rigs. In 2010 their oil rig K.S. Endeavor caught fire and exploded when it was operating off the coast of Nigeria. Two workers were killed, and 152 had to be evacuated from the rig. A buildup of gas pressure apparently contributed to the explosion.

The installation and maintenance of oil platforms is dangerous work. Those who were injured in an accident may be protected under the Jones Act. If you were hurt in an offshore accident, contact us using the online form to discuss your case today.
