Saab Seaeye ROV systems are offered with the option of a Launch and Recovery System (LARS). When deck space is limited, crane-based LARS are the solution. This will include a skid-mounted integrated winch, power pack, and marine crane.

The Launch and Recovery System (LARS) comprises:

  • Skid base
  • Protection and lifting frame
  • Lifting slings and spreader bar
  • Articulated marine crane
  • Umbilical winch with level wind
  • Electro hydraulic power pack (HPU)
  • Umbilical sheave
  • Lock latch assembly with hand pump or remote hydraulic release mechanism (optional)
  • Rotary and Stationary Junction Boxes
  • Optional Zone 2 certification
  • Slip Ring

The system described below as an example is the 1100m Zone 2 Crane LARS.

The system is designed and DNV approved, with an outreach of 4.4m and a max SWL of 5500kg (line pull) and a winch capacity sized to accommodate 1100 metres of 32mm diameter Saab Seaeye armoured lift umbilical.

All hydraulic power requirements for the Articulated Crane and Winch are provided by the Electro Hydraulic Power Pack (HPU).

For transportation and shipping, the Articulated Crane folds and is locked in the stow position.
