Oceaneering debuts new ROV for Statoil contract

Offshore staff

HOUSTON Statoil has awarded Oceaneering International Inc. an eight-year contract to provide two work-class electric ROVs for its Cat-J jackup drilling rigs in the North Sea.

Statoil’s Cat- J rig is a fit-for-purpose harsh environment jackup for operations in both surface and subsea wells in the shallow-water segments on the Norwegian continental shelf. Designed to work primarily for drilling and completion of production wells, Statoil said it can operate at water depths from 70 to 150 m (230 to 492 ft) and drill wells down to 10,000 m (32,808 ft).

The newest addition to Oceaneering’s fleet, the magnum-class eNovus ROVs are currently being built in-house at the company’s Morgan City facility. The design will include capabilities seen in the Nexxus ROV, such as remote piloting and automated control technology.

Also incorporated will be a new automated Cartesian Manipulator control system that enables it to function in an XYZ plane. This vehicle maintains work class manipulator capabilities via a dedicated hydraulic circuit. 

Tooling versatility has been increased by an integrated power and control system for electrical tools, as well as a dedicated hydraulic power unit for traditional tools.

By featuring a hydraulic system for conventional tooling operations, Oceaneering said that the eNovus will provide a cleaner and more efficient approach to subsea operations. Furthermore, the company believes that greater reliability will be achieved with more precise automated control and enhanced diagnostics.

Kevin Kerins, senior vice president, Underwater Vehicle Technologies, said: “The newly advanced ROV will also serve as the basis for a future hybrid between the autonomous underwater vehicle and ROVs.”

The designs will be complete in 2Q 2016, Kerins added.
