Single Basket Launch and Recovery System (TPI Approved)

JK Subsea Engineering Pvt. Ltd. is a trusted single basket LARS manufacturer and supplier, designing and manufacturing a TPI approved Launch and Recovery System for the safe, efficient deployment and recovery of commercial divers. Built for demanding offshore and marine operations, our LARS solution delivers reliable, controlled handling throughout every diving operation.

What is a Single Basket Launch and Recovery System?

A single basket launch and recovery system, or single basket LARS, is a deck-mounted piece of diving equipment that lowers and lifts a diver basket into and out of the water using an A-frame and hydraulic winches. It’s built to give commercial divers a safe, controlled way to enter and exit the water, even in challenging sea conditions, while keeping the footprint on deck as compact as possible.

Key Features of Single Basket LARS

Our single basket launch and recovery system is engineered for safety, durability, and reliable diver handling on offshore vessels and barges.

  • TPI Approved & IMCA Compliant: Designed to IMCA D018 and D023 guidelines and TPI approved for added assurance on safety and quality.
  • SS316L Stainless Steel Basket: Built for two-diver capacity from marine-grade SS316L, giving exceptional corrosion resistance and a long service life.
  • Integrated Cylinder Storage: The basket accommodates 2 x 50 ltr x 20 bar breathing air cylinders, with an integrated storage cage for diving tools and accessories.
  • Compact A-Frame with Dual Power Packs: A primary A-frame rated for 1.5 tons runs on two completely independent hydraulic power packs housed in a single partitioned tank.
  • Man-Riding Guide Weight Winch: Hydraulically set for around 1 ton and tested to 1.2 tons per IMCA, running at 18 m/min with 150 m of 13 mm dia wire.
  • Clump Weight for Stability: A 350 kg clump weight minimizes the effect of underwater currents and improves control of the diver’s umbilical.
  • Twin-Motor Hydraulic Power Unit: A self-contained HPU with a twin motor setup, safety package, and adjustable relief valve set at 170 Bar.
  • Container-Ready Transport: Fits into a standard 20 ft shipping container in its resting position for easy mobilization.
