    LONDON -- Shell and Oceaneering International have set a new industry record in subsea well intervention by replacing a failed subsurface-controlled subsurface safety valve in the Gulf of Mexico using an openwater wireline technique at a water depth of 2,673 ft (815 m).

    Until now, openwater wireline has only been deployed in shallower waters, predominantly in the North Sea, the companies say.

    Oceaneering International, Inc. provided the vessel and services for the operation. The company's subsea intervention lubricator system (SILS) is designed to perform wireline-based subsea well interventions without a drilling rig or large multiservice vessel and workover riser.
