BROUSSARD, Louisiana -- In June, Delmar Systems toppled BP’s decommissioned South Marsh Island 205B platform in a water depth of 523 ft (159 m) using the M/V Edison Chouest.
For the project, Delmar employed its conventional anchor handling and rigging methods and an anchor handling vessel (AHV) already working in the field to safely topple the platform. Toppling operations for the 1,700-ton (1,542-metric-ton) portion of the platform were completed in approximately 14 hours using a single AHV, the company reports.
“As part of the decommissioning process, Delmar’s platform toppling services are a cost effective alternative for the conversion of fixed jacketed structures into artificial reefs,” says Josiah McVicar, Delmar’s project manager. “We can use an already contracted or spot-hired AHV to pull platforms over in a safe manner using existing equipment and techniques. This allows for schedule flexibility and significant cost savings to operators that want to convert decommissioned platforms into artificial reefs for the benefit of Gulf of Mexico marine life.”
