Subsea dredging


A range of subsea dredging systems designed for the de-burial and clearance of debris, sediment and soil during subsea operations.

From subsea pipeline and structure inspection, maintenance and repair to decommissioning, our systems are engineered to deliver reliable, high performance dredging capability in harsh underwater environments.

UCS dredging systems also incorporate rock dump removal and drill cuttings remediation, ensuring minimal operator impact on the underwater environment.

Dredging case study

Dredging, coating removal and cutting of damaged pipeline for Allseas UK

Allseas UK, tasked with developing the pipelines connecting the Total Laggan-Tormore gas fields 125km north-west of the Shetland Islands, encountered a damaged flowline due to a dragged vessel anchor.

The initial phase of the project involved the use of an 8” UCS Dredge System with a bespoke-designed high pressure Barracuda head to clear a channel under the damaged pipework. The Coating Removal Tool (CRT) effectively and rapidly removed concrete coating and 3LPP undercoating to a depth of 1.2m.
