DP Workboats; a new era for Multicat type vessels Acta Marine has 40 years of experience operating 40 workboats globally. They were the first to install dynamic positioning (DP) systems on workboats in 2007. Currently they have 4 DP workboats that can perform tasks like trench backfilling, water jetting, offshore maintenance, and vibrocoring in ultra-shallow draft conditions, competing effectively with larger DP vessels. Their DP workboats are equipped with bow and stern thrusters for excellent position holding and can support additional work like trenching, ROV operations, and cable laying/burial.

NON DP Cable & Pipeline (re)burial Remedial lowering of cables / pipeline Post-lay technology - suction dredging with jetting - 4-point mooring - Life tracking of burial process Very effective and safe for shore-ends, crossings and exposed parts. Succesfully applied on live gas pipelines and power cables.
