Kreuz Subsea Expands ROV Fleet

15 August 2011

After winning a five-year contract with Shell in Brunei, Singapore-based Kreuz Subsea has added a Saab Seaeye Cougar XT to its ROV fleet. Operations manager, Robert Black recognises the need to compete on a world stage where the search for oil keeps going deeper and conditions are more difficult. He was particularly keen on a vehicle that could manoeuvre into tight spots.

Robert Black inspects the Seaeye Cougar XTFor safety's sake, Robert Black believes that highly responsive and capable ROVs should take over many more diving tasks, explaining that their client's wish is to minimise diver time in the water.

The Cougar XT's control and response comes from its six thrusters: four of which are vectored horizontal thrusters and two vertical. Each thruster has velocity feedback for precise control in all directions and is interfaced to a fast-acting control system and solid-state gyro for enhanced azimuth stability.

The Cougar XT configuration chosen by Kreuz in conjunction with Oceanvision, Saab Seaeye's Singapore-based distributor and Far East service hub, makes the ROV a versatile light work vehicle suitable for a wide range of operations.

It includes a Tritech Super SeaKing sonar; a Kongsberg high-definition low-light camera and a colour zoom camera; a dual five function heavy duty manipulator; and a CP proximity probe and contact probe.

A tether management system is also supplied with a stainless steel cage and 200 metres of tether, along with its own Seaeye mini wide-angle B&W camera.

An A-frame launch and recovery system is included with 1,600 metres of armoured umbilical.

The whole system comes with its own purpose-built 20 foot air-conditioned control and workshop container.
