The Jemar Norpower 30ft Seismic Workboat is a special designed workboat for cable handling operations at sea. It can operate as a “stand alone” workboat on survey vessels with weight or space limitations or 2nd Workboat onboard “full size” survey vessels. This spare workboat will fit onboard all types of mother vessels.
It is the biggest and strongest of our seismic workboats.
Vital parts of the boat-construction are strengthened based on experience from rough handling of workboats on purse net seiners, Supply vessels in the North Sea, and supply of more than 100 workboats for seismic operations over the last 15-20 years.
The workboat is certified as a decked boat, and the shape of the hull forms a boat with square stern and deep keel, trim and bowline inclining forward. The deck is self-drained and large flush work deck behind the winch, for working or passengers (Crew transfer). It is fully equipped for all kinds of cable work like cleaning cables, changing streamer sections, repairing birds and towing tail bouyos. Due to the variable pitch propeller and the hull design the boat is able to tow more than 3 tons and obtain a speed of more than 20 knots. The strong construction and solid fender make the workboat endure rough treatment. Jemar Norpower Seismic Workboat has excellent towing characteristics and high stability and considerable surplus buoyancy make the boat practically unsinkable.
