Lifting & Handling
5t DNV 20ft containerised LARS
A self-contained 5-tonne launch and recovery system in a 20ft container footprint, plug-and-play, wirelessly controlled, with an optional inbuilt handling system and an outboard cantilever platform.
A compact launch and recovery system designed for rapid, low-fuss mobilisation: a 5-tonne SWL A-frame LARS with its hydraulic power unit, winch and controls integrated into a base frame that fits a 20ft ISO container footprint. It ships like a container, sea-fastens simply and is set up plug-and-play, so deployment capability can be added to a vessel quickly and removed when the campaign ends, without permanent modification. An optional inbuilt handling system can be specified to suit whatever the payload needs.
Plain deck or outboard cantilever
It comes in two standard configurations. The plain-deck version mounts on the deck within the container footprint. The cantilever-platform version adds a platform on the outboard edge that reaches out over the side of the vessel, so you can launch and recover at the vessel’s edge without building additional seafastening structure out to the side. The cantilever brings the over-side reach into the LARS’s own engineered, sea-fastened footprint rather than a bespoke deck extension.
What problem it solves
Getting a 5-tonne-class deployment system onto a vessel usually means a bespoke install and significant mobilisation. A containerised, self-powered LARS with wireless control turns that into a fast, repeatable operation, the same modular philosophy as our Cranetainer, applied to over-boarding and recovery of corers, tooling and similar payloads.
