METHOD TO OPTIMIZE AN ANTI-SWAY FUNCTION

For optimizing an anti-sway algorithm for the transport of a load by a hoisting appliance spanning a hoisting area and comprising a trolley, a reeving system and a tool handling the load, a control device is able to: create a first table giving angle offsets of the trolley, depending on physical characteristics of the load and on mechanical parameters related to the trolley, the angle offsets being determined by measurements of inclination angles of the trolley, create a second table giving probabilities of a secondary sway of the load depending on physical characteristics of the load, on mechanical parameters related to the reeving system and on measurements of acceleration and angular position of the tool, and transport the load in the hoisting area by using an anti-sway algorithm taking into account the first table and the second table, wherein anti-sway algorithm takes as inputs dynamic parameters of hoisting appliance comprising the current position of the trolley, the load and the current angle of the load with respect to the trolley.

VESSEL AND METHOD FOR INSTALLATION OF A PILE ADAPTED TO SUPPORT AN OFFSHORE WIND TURBINE

A vessel and a method for installation of a pile adapted to support an offshore wind turbine are described. The method includes a) suspending the pile from a hoisting cable in a substantially vertical orientation; b) providing a lower end of the pile in a pile holding system limiting horizontal motion of a pile portion held by the pile holding system; and c) lowering the pile with the pile being held by the pile holding system. The lowering includes at least lowering the pile through a splash zone of a body of water, and during step c), two tugger lines are directly or indirectly connected to the pile at a location between the pile holding system and the hoisting cable, said tugger lines being operated to damp motion of the pile in two respective horizontal directions.
