Heave Chief

Based on our patented Balanced Heave Compensation technology, we've built a heave compensator with perfectly adjustable tension control, constant over its full stroke.

It is able to fast lift 100% of its safe working load (SWL), prevent re-hits, control DAF under 1.1. and actively follow any barge motions.

It's available for keeping loads still in a floating crane hook (e.g. TP installations) or to fastlift components from a heaving deck (e.g. WTG or Monopile feedering)

With the Heave Chief, any load can be held still, relative to a fixed object, even when the crane hook of the floating vessel is moving up and down. The machines can handle vertical displacements of up to 3,5m with a speed of 0,9m/s. Depending on the vessel and heading, this allows you to work in seastates up to Hs 3.0m.

It can be used to place transition pieces onto monopiles, secondary steel structures, modules onto topsides, or even complete topsides

Using our Heave Chiefs, we can simultanously compensated moving crane hooks (see 'floating installations'), while matching the motions of a moving target. For example floating installations onto floating turbine foundations. Our small motion reference unit (MRU) container, placed onto the target, will sends its movements wirelessly to our Heave Chief, which is automatically following these motions ('Follow-mode').
