English to French Tech/Engineering Patents (in a patent) ANTI-TWIST FRAME, VESSEL AND METHOD FOR LOWERING AN OBJECT IN A WATER BODY

An object of the invention is thus to provide a method for lowering an object in a water body, wherein the method can be employed in a wide range of wind/wave/swell directions and twist of the hoisting cable is minimized.

The method advantageously allows the vessel's heading to be substantially aligned with the wind/wave/swell direction prior to the lowering opération, by proper sélection of the connection point of the anti-twist wire on the ATF and the second hoisting cable (which could also be provided with a second ATF) and by selecting matching positions of the first and second hoisting means during arrangement of the anti-twist wire, such that during lowering twist of the first hoisting cable is minimized. The inventor has found that in practice the method can be carried out for a vessel heading range of 360° (i.e. omnidirectional). This is unheard of in the industry.

Method comprising the steps of:
a) adjusting the vessel's heading (29) such that the vessel is substantially aligned 10 with the wind/wave/swell direction (28),
