LARS – Launch and Recovery Systems

A LARS (launch and recovery system) is the equipment that deploys vehicles and instruments such as ROVs, USVs or CTD rosettes from a ship and recovers them. We design and manufacture launch and recovery equipment for the most demanding requirements, basing our work on the functions they must fulfil, achieving maximum operability, productivity and safety of the equipment.

LARS, launch and recovery, system, craft

FERRI LARS (Launch and Recovery Systems) are designed to meet the most demanding operations in the marine and scientific industry. Their versatility allows the handling of everything from ROVs and CTD rosettes to manned submersibles, sonars, torpedoes and Unmanned Surface Vehicles (USVs).

LARS, side A-Frame, ROV, CTD

The specialized A-Frames, which can be integrated with winches, optimize launch and recovery manoeuvres, while the telescopic and articulated arms provide the precision required for oceanographic research.

LARS, launch and recovery, system, Defence, USV, certified

We also develop modular systems for the recovery of fishing vessels and drifting objects, as well as articulated cranes with docking-heads that facilitate work with umbilical equipment and signal systems.

For USVs, we design specific solutions with floating protection elements and ATEX certifications that guarantee safety in explosive environments.

LARS, offshore, industrial, deck

Every LARS system is conceived to maximize efficiency and reliability in critical manoeuvres, even in very heavy seas, establishing itself as an indispensable tool for complex operations in any condition.

Defence

LARS for Defence

In tactical missions, speed and safety are not optional. FERRI LARS integrate harmoniously and strategically into the structure of military vessels, becoming an indispensable ally for exploration, defence and rescue missions in open waters.

Our combination of A-Frames, winches and telescopic booms enables extraordinarily fast launch and recovery manoeuvres. These systems are designed to reduce operating times when handling sonars, torpedoes, USVs and rescue equipment, ensuring mission continuity and supporting tactical manoeuvrability whatever the sea conditions.

Megayachts

LARS for Megayachts

In the megayacht sector, making the most of space and respecting the vessel’s design are paramount. That is why at FERRI we design and integrate fully customized LARS — including cranes, capstans and transverse arms — that adapt perfectly to the hull geometry, the working load and the available space.

Our equipment ensures high-precision launch and recovery of tender boats, limo boats, rescue craft and private submarines. Our most notable developments include LARS with telescopic arms for submarines, backed by prestigious certifications such as Lloyd’s Register and MED, which guarantee safe, flawless and discreet operation.

Completed projects

Ships and programmes for which FERRI designed and built this equipment. Tap each one to see the challenge and the solution.

Duque de Ahumada · Port and starboard LARS for rapid intervention

Spain · Guardia Civil · Offshore patrol vessel (OPV)

Duque de Ahumada

Port and starboard LARS for rapid intervention

8 t + 4 t heavy and light craft

The challenge

Launch and recover the ship's tactical intervention craft, simultaneously or independently.

The FERRI solution

An 8-tonne LARS for the heavy intervention craft and a 4-tonne LARS for the light rapid-response boat, designed for different interception and rescue vectors.

The ship

The largest ship in the history of the Guardia Civil Maritime Service, built by Astilleros Armón and co-funded by Frontex.

BAP Carrasco · Telescopic LARS for workboats

Peru · Peruvian Navy · Polar oceanographic vessel

BAP Carrasco

Telescopic LARS for workboats

The challenge

Operational safety and scientific versatility: launching support boats even in rough water, without interrupting missions.

The FERRI solution

Long-reach telescopic arms keep the boat clear of the hull to prevent swell impacts. Their compact design beneath the upper deck frees up working space on the main deck.

The ship

Built by Freire in Vigo, polar class PC7; since 2017 the platform for Peru's Antarctic expeditions.

Other FERRI equipment on board

A-frame, side LARS for CTD rosettes, oceanographic, fishing and traction winch system, knuckle-boom cranes.

Pegaso · Transverse LARS in below-deck hangar

Malta · Oceanographic explorer yacht

Pegaso

Transverse LARS in below-deck hangar

14 t over either side

The challenge

Launch and recover workboats and a crewed mini-submarine from an interior hangar.

The FERRI solution

A crane made to measure for the ship and the submarine, for loads up to 14 t on either side, with minimal hangar headroom and megayacht-grade finishes.

The ship

An expedition yacht of about 73 m launched by the Freire yard in Vigo; its submarine dives to about 160 m. She now sails as Naia.

Other FERRI equipment on board

Stowage cradles for the workboats and the submarine.

Hodor · Two telescopic arms for submarine and rescue boat

Cayman Islands · Superyacht shadow vessel

Hodor

Two telescopic arms for submarine and rescue boat
