Global Marine Systems adds jet trenching ROV to portfolio

Global Marine Systems Limited has extended its subsea capability with the acquisition of a powerful jet trenching ROV. The new submersible compliments the existing burial equipment portfolio and is designed for pre and post-lay trenching as well as simultaneous lay and burial in the offshore subsea cable sectors.

The new addition is the Q1000 Jet Trencher, whose modular design allows it to be easily mobilised onto vessels. With 1000 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 at a speed of up to 400 m per hour.

Operationally rated to a depth of 1000 m, the Q1000 is easily 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 state of the art cable detection and tracking system results in time-saving, precision burial. In addition to this, the jet trencher is able to handle product up to 500 mm in diameter, increasing the scope of work that Global Marine is able to undertake.

The high specifications of the Q1000 Jet Trencher will enable the submersible to operate globally in extreme environments and in challenging weather conditions. For this purpose, it has heavy latch beam Launch and Recovery Systems (LARS) designed for Sea State 6.

"As a company we constantly seek to find ways to enhance our services, and to provide engineered solutions that meet customers' demands and deliver these with versatility, innovation and accuracy." Commented Bruce Neilson-Watts, Director Strategy & Operations: "It is an approach that has allowed Global Marine to successfully operate in multiple business sectors, even in the present economic climate. The acquisition of the Q1000, is a good example of our continued commitment to providing exceptional subsea engineering services globally."
