The vessel is fitted with a fully redun-dant Kongsberg K-Pos DP21 Dynamic Positioning System.

There is one HiPAP 500, two satel-lite positioning systems (DGPS) and a Fanbeam.


Cranage Capacities

The pedestal mounted active heave compensated knuckle boom crane is located on the starboard side of the main deck. It has a 250 T capacity at a radius of 13 m.

There is one auxiliary crane with a ca-pacity of 3 T and 16 m, together with two Rolls Royce Marine Safe Deck AH-handling cranes mounted on each cargo rail.

An optional stern mounted A-frame could have up to 350 T capacity.


Work Class ROV

The Triton XLX is a heavy duty work class ROV system, able to cope with the most demanding off-shore applications. A wide range of modern tooling and sensors can be accommodated and it has been de-signed to allow prolonged and accu-rate operation.

General DescriptionDepth rating 3,000 MSW Power 150 HPPayload Capacity 250kgThrough Frame Lift 3,000 kgControl Modes Heading, Depth, Altitude & Auto PositionTMS Top Hat Design

CapabilitiesThe ROV has a power unit rated at 150HP with 4 horizontal and 4 vertical thrusters. The Thruster Control Manifold is equipped with 4 spare proportional valves and 2 spare So-lenoid valves, and the tooling manifold is fitted with 5 spare proportional valves and 1 spare Solenoid valve. The ROV is fitted with Schilling T4 seven-function and and Schilling Rigmaster five-function manipulators, 16 station proportional main manifold and 12 station proportional tooling manifold as standard. The survey junction box allows for the easy integration of all modern sensors and additional cameras.
