Everything You Need to Know About Launch & Recovery Systems (LARS): A Complete Guide

Launch & Recovery Systems (LARS) are designed for the safe and reliable deployment and recovery of equipment and personnel in offshore and subsea operations. Their main function is to ensure stability and control during lifting, lowering, or deployment, reducing risks to both personnel and equipment.

A LARS launch and recovery system is different from standard marine cranes because it includes features such as heave compensation, precise winching, and controlled handling. Standard cranes cannot manage sensitive underwater equipment or divers safely in rough sea conditions.

LARS enhances safety, operational efficiency, and reliability. For example, an ROV LARS allows precise deployment and retrieval of remotely operated vehicles, protecting equipment and improving mission success in subsea operations.

A LARS launch and recovery system works in three main stages: Deployment → Operation → Recovery. Equipment or divers are safely lowered, operated underwater, and then retrieved in a controlled manner.

Key components like the A-Frame, davit, winches, hydraulic power units, control panels, and heave compensation work together to ensure stability and precision during deployment and retrieval.

The LARS diving system allows safe deployment and recovery of divers, even in rough sea conditions, ensuring both diver safety and operational efficiency.

Automated Launch & Recovery Systems reduce manual errors, improve operational speed, and provide precise control over equipment and diver handling, making offshore operations safer and more efficient.

These systems are built for remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs). They provide precise deployment, secure recovery, and stable operation during subsea inspections, surveys, and construction tasks.

Used in commercial diving, diving bells, and wetbell operations.

The LARS diving system ensures divers are deployed and retrieved safely, even in rough sea conditions. It includes features like diver baskets, controlled winches, and monitoring systems for improved safety and efficiency.

Compact, lightweight, and transportable systems that can be installed on smaller vessels or temporary offshore setups. These systems allow flexibility for short-term projects without sacrificing safety or control.

Designed for integration with vessel deck structures or moonpools. These systems are ideal for heavy-duty operations and can handle larger payloads, offering stability and precision for permanent offshore installations.

Tailored for underwater surveillance, deep-sea research, and specialized operations. These systems are engineered for precise handling, high reliability, and safe deployment of sensitive or classified equipment.

All these Launch & Recovery Systems are designed to ensure safe, reliable, and efficient operations, whether for commercial, scientific, or defense purposes.

The structural frame provides the main support for deployment and retrieval operations. It ensures stability and strength for handling heavy equipment or divers during offshore and subsea operations.

These winches allow precise lifting and lowering of payloads. Controlled winching reduces risks to equipment and personnel, providing smooth and reliable operation.

HPUs supply the necessary hydraulic power to operate winches, davits, and other system components, ensuring consistent and controlled movement.

Modern Launch & Recovery Systems come with control panels featuring monitoring and automation capabilities. Operators can manage deployment speed, tension, and positioning with accuracy.

Heave compensation stabilizes the payload by counteracting vessel movement in rough seas. This feature is critical for sensitive equipment and diver operations.

LARS include redundant brakes, interlocks, and emergency stop systems to protect both personnel and equipment during deployment and recovery.

For diving operations, specialized components like diver baskets, wetbells, and monitoring tools are integrated to ensure safe and controlled handling of divers. The LARS diving system provides stability, precise positioning, and enhanced safety during underwater tasks.

All these components work together to make LARS launch and recovery systems reliable, efficient, and safe for a wide range of offshore and subsea applications.
