The Kongsberg Maritime AS Launch And Recovery Systems For Rov Lars is a dedicated launch and recovery system for remotely operated vehicles. A LARS controls the movement of the ROV and, where fitted, its tether-management system or cage between the vessel, splash zone and operating depth. Kongsberg systems can include an A-frame or overhead handling structure, ROV winch, umbilical management equipment, docking head, controls and hydraulic or electric drives in a vessel-specific arrangement. The equipment is installed on offshore, anchor-handling or subsea vessels and is designed to reduce uncontrolled motion and protect the ROV and umbilical during launch and recovery. Unlike a general deck crane, the system is integrated around the geometry, weight, umbilical and docking requirements of a specific ROV spread. The exact load limits, deployment speed, sea-state envelope and compensation features must be taken from the certified system documentation; refer to the manufacturer documentation for the exact figure.

Service

Service notes.

What our service work and the manufacturer documentation say about keeping this model running.

Inspect the ROV winch, umbilical, level wind, sheaves, docking hardware, A-frame/overhead structure, pins, cylinders and drives. Function-test brakes, emergency stops, latches, limits, tension monitoring and compensation functions where fitted. Check structural welds and foundations for corrosion or cracking and verify umbilical handling without sharp bends or crushing. Load tests, umbilical discard limits and operating envelopes must follow the certified Kongsberg/ROV documentation.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
