Launch and Recovery Systems (LARS) play a crucial role in marine operations, especially in commercial diving. These systems are designed to deploy and retrieve divers or equipment from the water, ensuring safety, efficiency, and reliability. In commercial diving, where precision and safety are crucial, LARS are indispensable pieces of equipment. They enable the seamless transition of divers and subsea equipment from the deck of a vessel to the underwater environment and back. This article covers the definition of LARS, uses, and products by iSubC diving equipment.

Definition and Use of LARS in Commercial Diving

A Launch and Recovery System (LARS) is a mechanical system used to deploy and recover diving bells, wet bells, or other subsea vessels or equipment. In commercial diving, these systems are essential for maintaining the safety and efficiency of underwater operations. LARS typically consist of an ‘A’ frame or crane, hydraulic winches, and control systems that work together to lift and lower equipment into and out of the water.

In commercial diving, LARS provide several key benefits:

  1. Safety: They ensure the safe handling of heavy and sensitive equipment, reducing the risk of accidents during deployment and recovery.
  2. Efficiency: LARS streamline operations, allowing for quick and precise deployment and recovery of divers and equipment.
  3. Reliability: With robust design and engineering, LARS can withstand harsh marine environments, ensuring consistent performance.
