Technical specifications
DESCRIPTION
Sea Mole provides high power trenching
capability for the burial of cables up to a depth
3.0m. Sea Mole is a high powered class-leading
Trenching ROV with 1200HP, utilising either
high flow or high pressure water jetting to
optimize trenching in order to suit the seabed
conditions. The vehicle can be fitted with a rear
eductor, or backwash swords, to enhance burial
in specific soil conditions. Sea Mole is
configured to cover a range of burial depths up
to 2.5m, maintaining this depth even in strong
soils. Fitted also with a Teledyne Dual Track
TSS440 & 350 allowing Sea Mole to provide
real-time burial data to ensure project
deliverables are being met right away.
