Subsea engineering company Oceaneering International has completed an integrated rig services campaign offshore South America using its remotely operated survey (ROS) group.

In June last year, Apache Corp contracted Oceaneering to provide integrated rig services with the drillship Noble Sam Croft.

The drillship provided ROS, a remotely operated vehicle (ROV), and an acoustic doppler current profiler (ADCP) for a potential three-well campaign.

Survey Services global business development manager Chris Echols said: “The ROS system eliminates the need to remobilise survey equipment and personnel for subsequent moves.

“Oceaneering surveyors in our remote control monitoring stations communicate and coordinate with the rig personnel and company representative during rig move activities.

“The ADCP systems on the drillship are maintained, recovered, and deployed by the ROV crew. This minimises personnel on board, and greatly reduces the logistics and costs associated with mobilisations in remote areas.”

All ROS surveys are supported by the company’s Remote Control Monitoring Stations in Houston city of Texas and Lafayette city of Louisiana, both in the US.

Oceaneering said it has now recorded a milestone 150,000 hours of ROS operations, with 99% uptime, without any client operations or vessel downtime.

Echols added: “This milestone ushers in a new era for remote survey and positioning services. Advancements in these areas have enabled operators to rethink the way they conduct work.”

In February this year, Oceaneering secured a contract from units of BP to provide comprehensive riserless light well intervention (RLWI) services offshore Angola.

In January this year, Oceaneering and Aquaterra Energy collaborated on decommissioning wells. Their partnership also offers late-life solution packages for the North Sea oil and gas industry.
