Wreck Removal, Oil Rig

Trinidad & Tobago | Trinidad and Tobago

Off the coast of Trinidad & Tobago, a jack-up rig suffered a catastrophic leg failure. Resolve Marine mobilized personnel on an emergency response basis; however, the situation quickly transitioned from an active emergency response to a wreck removal. 

The operation was tackled in two distinct phases: first to stabilize the structure and mitigate environmental risks of onboard pollutants and second to safely remove all major components of the rig from the site.   

Phase One focused on securing the compromised rig and addressing immediate environmental hazards. In doing so, Resolve Marine removed 34.5 m³ of hydrocarbons as well as 81 containers and bulk deck cargo items. Hazardous drilling materials, including caustic soda, barite, and assorted chemicals were extracted, preparing the rig for controlled dismantling.  

Phase Two of the operation was the removal of the Rig 110 topsides, the rig mat, the drill floor and drill derrick. Resolve Marine mobilized its specialized salvage barge RMG 1000, equipping it with two American 11320 cranes. These cranes were used to remove the drill derrick and drill floor, including two tandem lifts with a maximum pick weight of 183 tons. Phase Two also included the removal of Rig 110’s topside by positioning a submersible barge outfitted with engineered grillage designed by Resolve Marine’s naval architects, to support the structure. This was followed by the controlled cutting of jack-up legs, allowing topsides to be safely supported and transported to a separate site.   

Final debris removal and bottom scanning were completed to the satisfaction of the field operator.  

Upon the completion of services, the casualty site was clear of all traces of the rig, and the well platform was returned to the field operator.
