Forum Energy Technologies (F-E-T) outlined its latest remotely operated vehicle, the work class XLX-C ROV at

The unit is a more compact version of the frm’s Perry XLX, but with similar capabilities. It has been design from the inside out, starting with an all-bolted construction open central frame design, with removable side protection panels.

Payload can be attached at the front (250kg), side (150kg) and rear of the ROV (300KG). As with other Forum ROVs, the

ICE (Integrated Controls Engine), which includes auto-functions, and system diagnostics.

Auto-functions include auto head- ing survey, auto cruise, with speed adjustment on the fy, and dynamic braking when manual thrust commands

Aberdeen in February.

IWOCS are used to perform testing, control and monitoring functions on sub- sea equipment, including wellheads and gas lift modules, for example.

Gregor McPherson, sales director at

Caley, says traditionally, the IWOCS cable is clipped on to the riser as it is deployed to the subsea wellhead or manifold, a time-consuming process requiring use of an overhead crane and human intervention.
