MODULAR LARS SYSTEM

Lidan Marine’s modular LARS system is designed to meet every situation and condition. This means that the system can be configured from HPU and Winch with standard controls to a complete LARS system with high-performance Active Heave Compensation. Each system is designed for modularity and multiple combinations are available to meet different installation options and project specific requirements.

Scalable Active Heave Compensation (AHC) performance

Closed loop hydraulic in HPU and Winch drive prepared for high accuracy control. Select hydraulic power unit to scale capacity for different project needs. Smart software to reduce the degree of compensation when the capacity limit is reached resulting in smooth residual motion.

AHC LIGHT

Low-cost compensation to increase weather window.Software reduces the degree of compensation when reaching the capacity limit. The result is a smooth residual motion with less amplitude than without compensation. The operation window is increased.High vessel motion results in moderate TMS motion. Affordable option – Upgradable if requirements increase.


AHC MEDIUM

Cost-effective compensation for more demanding situations. Provide high accuracy AHC for operational conditions that are close to maximumweather conditions for deck operations on standard vessels. Smart software to reduce the degree of compensation when the capacity limit is reached resulting in smooth residual motion.


AHC HIGH

Accurate compensation for extreme sea conditions. High-end solution for most demanding operating conditions with huge accelerations. Additional winch interconnection kit to accommodate higher oil flowas higher power is required.
