Cable Trenching

Trenching expertise delivered by capable assets and teams

Solutions that include engineering support, project management and modern assets delivered by a proven team with an extensive track record.

Adding the high performance Q1400 trenching system to our Group assets enables us to undertake projects which require precise installation in challenging seabed environments. The Q1400 is able to perform jet trenching on subsea pipelines, cables and umbilicals in soils of up to 100KPA. Additionally, we can also perform mechanical chain cutting in soils of up to 250KPA.

The Q1400 is extremely adaptable and can uniquely transfer from jetting to cutting modes while at sea, avoiding the need to return to port for system changes. It consists of a common trenching module and separate tracked jetting and mechanical cutting skids, with a customised launch and recovery system (LARS) rated to Lloyd’s sea state 6. A deck-transfer skidding system enables safe mode changes at sea without craneage.

The Q1400 system is capable of free flying in jetting mode and operating in water depths of up to 3,000 metres. It has 1475 available horsepower with two 400KW high-pressure pumps up to 15Bar and 2,000 cubic metres per hour. Two additional 150KW hydraulic pumps provide low-pressure water and hydraulics. The system also has the capability to deploy an additional backwash tool or eduction and a tool to create backfill in soft clays.

SUBSEA CABLES

Jet trenching or cutting for various types of cables, providing protection from fishing and other risks. Trenching also provides cable stability, preventing movement on the seabed.
