Subsea partners offer excavation, trenching

Offshore staff

ELLON, UK – Subsea contractors Marin Group and Ecosse Subsea Systems have teamed to provide a one-stop excavation and trenching service to the oil and gas sector worldwide.

The association combines Marin's Evo System mass-flow excavation, claycutting, and jet sled technology with Ecosse’s SCAR plough for pre-cut, simultaneous, and post- lay trenching.

The latter is designed for launch and operation primarily from a conventional anchor-handling vessel without the need for lifting apparatus, but it can also be mobilized from dive support vessels. Its 2-10 m (6.5-33-ft) trenching depth capability has attracted interest in ice-affected arctic regions and the Caspian Sea.

Marin Group CEO George Stroud said: "Together we can provide a unique set of complementary techniques that gives clients the answer to a broad range of subsea trenching and excavation challenges, from shore approach work to complex full ocean depth operations.

"By working as an alliance, we are able to mobilize from one vessel which is a highly convenient option for clients as it offers them very significant savings on both time and money."
