SubscribeControlling the relative motion between floating objects has always been a challenge in Naval and Offshore applications.
To conquer the challenge you must be able to master technologies for passive as well as active compensation. The first generations of heave compensation were developed for Offshore application in the early 80’ties. Since then the resolution and sensitivity has increased dramatically.
Present systems handles accelerations up to 4 m/s2 and speeds at 4 m/s. Applying this heave compensation technology in cranes, ramps and winches allows for the handling of cargo between dock and ship, ship and smaller floating objects as well as between ships. It also allows for life rescue operations with a hoist from a larger ship without involving the risk of injuring personnel.
A weight that is lowered decreases its potential energy and this power needs to stored or consumed. As the weight of a handled object increase the stored in potential energy increases. The energy can be consumed in the thrusters or cooled down but as it increases the handling becomes an aspect to consider.
When using electric systems the storage is question of battery capacity; in a hydraulic system the storage is handled in gas accumulators. With edge cutting control systems supporting today’s pumps technology Lidan is able to supply high sensitivity motion compensation systems.
