Subsea Trenching System: SCAR 1
The Subsea Trenching System: SCAR Plough has been developed
to deliver an all-in-one or one-part solution to seabed preparation - boulder
clearing / trenching and cable/pipeline/umbilical lay and backfill operations.
In Boulder Clearance mode SCAR can remove boulders from
a pre-determined corridor from 10m wide in one pass, and can clear to significantly
wider corridor using multiple passes (trialled to 20m).
In Trenching / Multipass mode SCAR can cut 1.4m in the
first pass and significantly deeper with each subsequent multipass.
Bespoke feeder / cradle design to suit the cable / umbilical
/ pipeline in lay configuration, with pre-cut, simultaneous, post lay and
remedial options.
Backfill mode offers a low risk solution to burying product
to variable depths. In Backfill mode it will bury product, moving spoils
back in to the trench.
Operated sucessfully in harsh work environments 'West of
Shetland' and Humber Gateway.
