Perguntas Frequentes

Will Cranemaster® have any effect on peak loads for lifts in air?2018-09-11T07:38:42+01:00

Yes. When there is relative motion between the lifted object and the boom tip, a snap load will occur, increasing DAF and potentially lead to unacceptable high peak loads.  Cranemaster® will work as a shock absorber, efficiently removing these snap loads, reduce DAF and improve safety. Typically, this enables our clients to conduct such lifts in higher waves, thereby increasing the operational weather window.

What is the deepest operating depth for the Cranemaster® units?2018-09-11T07:15:38+01:00

As of today Cranemaster® has been used at 2700 meters water depth and is designed to operate down to 3000 meters. However, for deep water operations special depth compensation techniques may be required.

Can Cranemaster® be used to reduce dynamic hook loads when lifting through the splash zone?2018-09-11T07:12:36+01:00

Yes, the Cranemaster® is designed to instantly respond to its surroundings, take up slack wire and reduce dynamic loads.

Can Cranemaster® units be used together with AHC?2018-09-11T07:01:08+01:00

Yes, Cranemaster® units will work perfectly together with AHC that responds to inputs from an accelerometer.

What is the difference between Active Heave Compensation (AHC) and Passive Heave Compensation (PHC)?2018-09-11T07:00:00+01:00

Both Active Heave Compensation (AHC) and Passive Heave Compensation (PHC) are techniques used on lifting equipment to reduce the influence of waves upon offshore operations. AHC differs from PHC by having a control system that actively compensates for any movement using external energy. Passive systems reacts to external forces without additional energy to control the motion. 

Will Cranemaster® reduce motion in air?2018-09-11T06:57:30+01:00

No, as passive Cranemaster® units rely on external forces to reduce motion, it will have no impact on the movements of free hanging objects in air.
