About

Telescopic LARS in Vessel Equipment Configuration

The telescopic LARS belongs to the category of specialized marine lifting equipment and is used for outboard handling operations. Due to its design features, the system seamlessly integrates into the deck space without requiring complex modifications to the vessel’s structures.

Telescopic Concept as an Engineering Solution

The telescopic boom design allows for variable working outreach by extending and retracting sections within the structure. This approach enables equipment adaptation to various operating conditions and vessel layouts without increasing the footprint.

Suspended Design and Vessel Integration

The suspended configuration is applied when efficient load distribution between hull structural elements is critical. This integration layout simplifies equipment arrangement and accommodates the specific requirements of individual vessel designs.

Control Systems and Operator Interface

Modern solutions for marine launch and recovery systems provide user-friendly and intuitive control. The equipment can be integrated into the vessel’s control systems and operated from both local control stations and remote control panels.

Equipment Application in Marine Operations

The use of telescopic launch and recovery systems expands the vessel’s operational capabilities and enables auxiliary operations with a high degree of control. These solutions are utilized on various vessel types with specific equipment layout requirements, where the telescopic LARS ensures efficient use of the available space.

Manufacturing and Engineering Development

The development and manufacturing of this equipment class requires a comprehensive engineering approach and precise consideration of future operating conditions. Izhora Hydrosystems LLC designs and manufactures telescopic LARS based on in-house marine engineering expertise and industry standards.

Customized Design Approach

Launch and recovery systems are frequently tailored to specific vessel parameters and project requirements. Izhora Hydrosystems LLC delivers customized engineering solutions, ensuring seamless integration of the equipment into the vessel’s systems.

4. Additional Requirements

The LARS ensures secure storage when stowed for sea aboard the vessel, with no restriction on sea state.

The telescopic LARS is equipped with an active heave compensation system (damper) and shock absorbers to reduce impact loads, enabling the launch of the command boat during forward headway at speeds up to 5 knots and sea states up to code 3.

All electrical equipment is complete with cable glands and provided with external grounding terminals.

The LARS is designed for open deck installation (climate design OM1, GOST 15150-86).

The LARS is equipped with a transformer for charging the command boat battery.
