HERNDON, Virginia – Global Marine Systems Ltd. has acquired a jet trenching ROV. The new submersible is designed for pre- and post-lay trenching as well as simultaneous lay and burial of subsea cables.
The new addition is the Q1000 Jet Trencher, whose modular design allows it to be mobilized onto vessels. With 1,000 HP of total installed and variable jetting power, the ROV is suitable for trenching pipelines, umbilicals, and cables to a burial depth of 3 m (9.8 ft) at a speed of up to 400 m (1,312 ft) per hour.
Operationally rated to a depth of 1,000 m (3,281 ft), the Q1000 can be configured for use with either tracks or skids to suit the application and can be deployed for trenching operations on all seabed conditions, from fine sand to firm clay. Its cable detection and tracking system results in time-saving, precision burial, said Global Marine. In addition to this, the jet trencher is able to handle product up to 500 mm (19.5 in.) in diameter.
