Subsea Minerals
Launch and recovery systems for subsea mineral recovery
AXTech has extensive experience in complex lifting and handling operations for the subsea minerals sector.
We engineer highly specialised launch and recovery systems (LARS) for each client’s operational and environmental requirements — including:
- Integrated docking mechanism
- Snubbers
- Catch frames
- Systems for handling wires and umbilicals.
In-house engineering
Our in-house engineering includes advanced dynamic simulations to ensure accurate dimensioning of the complete lifting system.
We have delivered reliable solutions with proven uptime — incorporating features such as heave-compensated umbilicals and precise control for subsea machinery operating in extreme depths and dynamic sea states.
AXTech delivers complete engineered solutions — not just equipment.
We provide full-scope services from concept development and analysis t fabrication, delivery, installation, service, and maintenance.
Proven capability – 1000 t Launch and Recovery System
We delivered a 1000-tonne Launch and Recovery System to a mining vessel in 2020 .
The system enables safe launch and recovery of a subsea mining crawler operating at 300 metres depth, integrating a high-capacity hoist winch, A-frame tower, umbilical management and tensioning systems, and multiple riser handling units. With a Safe Working Load of 1000 tonnes, the LARS incorporates both electric and hydraulic drive systems, redundant control architecture, and automated wire-line tensioning.
Every component — from the 370-tonne hoist winch to the umbilical reeler and riser tensioners — is designed for precision, safety, and reliability under the toughest offshore conditions.
