Overview
Unique Group offers a comprehensive range of Launch and Recovery Systems (LARS) engineered for commercial diving, ROV, and subsea equipment handling. Our systems ensure safe and controlled deployment and recovery in demanding offshore conditions, supporting operations from shallow coastal tasks to deepwater missions.
Our LARS are used globally for surface-supplied diving, manned basket deployment, ROV launch, and recovery of subsea vehicles. With a strong track record in engineering containerised, modular, or bespoke LARS, we provide dependable solutions that meet both IMCA and class certification standards.
Key Components of Our LARS Solutions
- Diver Launch Frames: Open cage, 2-diver and 3-diver wet bell systems
- ROV Launch A-Frames: Dipping and telescopic designs with enhanced reach
- Hydraulic Winches: For vertical and horizontal deployment with load monitoring
- Umbilical Handling: Integrated sheaves and reel systems for diver or ROV support
- Control Panels & Consoles: Manual or remote operation with safety interlocks
- Containerised or Modular Frames: Designed for ease of mobilization and transport
Technical Strengths
- Capacity Range: Suitable for light-duty to heavy-duty lifting (up to ~15Te SWL)
- Compliance: IMCA D023/D018, DNV-ST-0378, Lloyd’s Register, ABS, BV, RINA
- Operational Depths: Supports surface, mid-water, and deepwater operations
- Deployment Modes: Manual, hydraulic, or remote-controlled activation
- Design Variants: Fixed, containerised, or vessel-mounted LARS configurations
- Safety Features: Load monitoring systems, emergency brakes, fail-safe latch mechanisms
Custom Engineering Scope
Each LARS is engineered to meet client-specific operational and environmental conditions. Key configurable elements include:
- Diver basket or wet bell size and capacity
- ROV type and launch footprint
- Sea state and motion compensation needs
- Vessel integration or skid-mounting options
- Control system integration (manual, radio, touchscreen)
- Electrical and hydraulic power interfaces
Use Case Scenarios
- Surface-supplied diving in offshore oil & gas projects
- Deployment of WROVs for pipeline inspection or repair
- Cable-lay and trenching support in offshore wind installations
- Naval and defence diving system operations
- Modular LARS packages for containerised dive spreads
Deployment & Operation
Our systems are designed for quick mobilisation and intuitive use. Many of our LARS fit within ISO containers or compact deck footprints, allowing for easy transport and integration on vessels of opportunity. For ROV operations, dipping A-frame systems offer extended reach into splash zones, enhancing launch safety and accuracy. Integrated winches and umbilical sheaves ensure smooth handling, while operator panels provide responsive, user-friendly control.
