LARS

ROV Launch & Recovery System enables to remove from the ship inside to outboard (or the reverse process) by the launch and recovery of the umbilical cable to realize the ROV release and retraction between the deck and water surface. The system includes A-frame, winch and hydraulic power unit. It is designed in accordance with DNV standards and is certified by DNV Classification Society, which works stably under very rough sea conditions. The whole operation process is remotely controlled by wireless, which is more convenient, efficient and safe.

Description

⊙The snubber has six main functions, including rolling, pitching, rotating, clamping, locking and pressing, guaranteeing the normal work under the harsh marine conditions.
⊙Cooperated with the lebus rope groove on the drum, the winch automatic and manual override spooling mechanisms can ensure the cable spooling neat and tight.
⊙Two control modes are available, including the remote waist hanging controller and short-range operating console.
⊙An encoder and a pin sensor are installed on the snubber to monitor the ROV depth and lifting weight in real time.
⊙The hydraulic power unit is driven by two pumps and electric motors. The LARS can function by one motor in case of an emergency.
⊙The A-frame can be customized to split type and telescopic type, saving transportation and deck space
