DIVING EQUIPMENTS
Underwater Light
J. K. Subsea Engineering Pvt. Ltd. is an underwater light manufacturer and supplier for the diving, subsea and hyperbaric industry. Our Underwater Light, Model No. JK-UWL-300, is a compact LED light that gives a 100° wide flood of 3000 K warm white light from only 1.5 W on a 12 VDC supply. The aluminium housing, tempered glass window and dual Viton O-rings are designed for use down to 300 metres of seawater. The LED is rated for 30,000 hours, so you get a long working life from a very small power load.

Single Basket Launch and Recovery System
Every commercial diving operation depends on one moment happening right, every time, the moment a diver goes into the water and the moment they come back out. J. K. Subsea Engineering Pvt. Ltd. manufactures the Single Basket Launch and Recovery System, Model No. JK-LARS-SB-ALPHA-CLASS, a class approved single basket LARS built to handle that moment with total reliability. This diver launch and recovery system combines a marine grade stainless steel two diver basket, a rated A-frame, twin independent hydraulic winches, and a self-contained hydraulic power unit into one compact package that folds down to fit a standard 20 ft shipping container. As a trusted LARS manufacturer for the commercial diving industry, J. K. Subsea builds this system to IMCA D018 and D023 guidelines, giving offshore operators a verified, class approved solution for deploying and recovering divers from any vessel or barge.
What is a Single Basket Launch and Recovery System (LARS)?
A launch and recovery system, widely known across the industry as a LARS, is the mechanical system responsible for lowering a diving basket into the water and lifting it back out in a smooth, controlled way. In commercial diving, this is not a secondary piece of equipment, it is core life support infrastructure. A poorly designed or unreliable diver LARS leaves divers exposed to vessel movement, sea state, and uncontrolled ascent or descent, which is exactly what a properly engineered system is built to prevent. Our single basket launch and recovery system is designed compliant with IMCA D018 and D023 and carries class approval, giving diving contractors a documented, third-party verified system instead of an unclassed in-house build. The basket, built from marine grade SS316L stainless steel, carries two divers along with their emergency breathing air supply, while the A-frame, guide weight winch, and main winch work together to keep every deployment and recovery controlled, even in demanding offshore sea conditions.
Key Features of the Single Basket LARS
Our LARS, also referred to as a 2 diver launch and recovery system, is engineered to handle two diver deployment and recovery reliably across offshore diving operations.
- IMCA Compliant Design: Designed to IMCA D018 and D023 guidelines, giving operators a verified, class approved diving handling system.
- Integrated Emergency Breathing Air Storage: Holds 2 x 50 litre x 200 bar breathing air cylinders as bailout supply, with an integrated storage cage for diving tools and accessories.
- Twin Independent Hydraulic Winches: One winch for the basket and one for the guide wire, each on its own hydraulic power pack for full redundancy if one system fails.
- High Quality 600 Amp Pole Switches: Built for repeated use, with guidance to shut down and allow cooling if the unit becomes hot during operation.
- Self-Contained Hydraulic Power Unit: 20 HP electric motor driving a twin motor positive displacement pump, with high oil temperature display and emergency stop as standard safety features.
- Container-Ready, 20 ft Footprint: Folds down to fit a standard 20 ft shipping container in resting position, cutting mobilisation and shipping costs.
- Marine Grade Stainless Steel Diving Basket: Built from SS316L for corrosion resistance and long service life, with full headroom for two fully deployed divers.
- Rated A-Frame with Skid: Primary A-frame rated for 1.5 tons, with a hydraulically operated extending ram and dual lock valves for safe, controlled positioning.
- Man Riding Main Winch: Set hydraulically for close to 1 ton and tested to 1.2 tons as per IMCA, running at 18 m per minute with a 150 metre, 13 mm diameter wire.
- Dedicated Guide Weight Winch: Double reeved through the guide weight to the A-frame, rated for 1 ton SWL and tested to 1.5 tons.
- 350 kg Clump Weight for Stability: Reduces the effect of underwater currents on the diver’s umbilical, improving control and operational safety.
- Weatherproof Marine Grade Electrical Control: Star and Delta starters in rubber-lined, weatherproof stainless steel control boxes, finished with double coat marine epoxy paint.
Applications of the Single Basket Diver LARS
Our single basket launch and recovery system supports commercial diving operations wherever divers need to be launched and recovered safely from a vessel or barge.
Offshore Oil and Gas Diving Support: Deploys and recovers divers during platform inspection, maintenance, and construction work.
Subsea Construction and Salvage Diving: Provides controlled diver handling during construction, salvage, and repair operations in open water.
Remote and Mobile Diving Projects: Container-ready transport makes this containerized LARS practical for projects requiring frequent relocation.
Diving Support Vessel (DSV) Operations: A compact, deck-mountable LARS system that fits DSVs and barges without consuming excessive deck space.
Marine Renewable Energy Projects: Supports diver deployment for offshore wind and other renewable energy infrastructure work.
Emergency Diver Recovery Operations: Twin winch redundancy and a dedicated guide weight system keep recovery reliable even if one winch fails.
