New ISU Plough Completes
First Work for CTC Marine
A new design ISU Plough built by SMD Hydrovision
has successfully completed its first work for
CTC Marine, burying an umbilical on the Venture
Annabelle field development for Subsea 7.
The plough is a 150te bollard pull machine specifically
designed for the burial of integrated service
umbilicals (ISUs) up to 5m in bend radius to a
trench depth of 1.7m. It is based on SMDH's Heavy
Duty 3m Plough (HD3) which has been extensively
used in the telecoms industry. In umbilical form
the plough provides high quality, low risk protection
of flexible products up to 230mm diameter in a
very wide range of ground types.
The plough is able to remotely load and unload
products on the seabed for post lay burial operations
without the need for diver intervention. Its performance
is further enhanced with 300kW of water jetting
for difficult to plough sands and a Rock Ripping
System to enable burial in fractured rock.
The plough can be further modified to accept
ISU's up to 15.5m minimum bend radius.
