Temporary holding system, vessel, and method for temporarily holding, during driving operations, a foundation pile intended to receive the mast of an off-shore wind turbine

A temporary holding system for temporarily holding, during driving operations, a foundation pile (E) intended to receive a mast of an off-shore wind turbine,

• wherein said temporary holding system (1) comprises:
• a sleeve (2) delimiting a through-duct (21), intended to surround a section of said foundation pile (E) and defining a longitudinal axis (21′), and
• a carrier frame (3) comprising an interface module (31) that carries said sleeve (2), and a base (32) that is intended to be secured to a floating vessel,
• wherein said sleeve (2) comprises:
• a primary section (2a), assembled to said interface module (31), and
• at least one secondary section (2b), carried by said primary section (2a) and rotatable between two configurations:
• a closed configuration to delimit said through-duct (21), and an open configuration to clear a lateral opening (2c) for a passage of said foundation pile (E),
• wherein said interface module (31) and said primary section (2a) are assembled using bearing means (5) intended to provide said sleeve (2), comprising said primary section (2a) and said secondary section (2b), with a rotational degree of freedom with respect to said interface module (31), about an axis of rotation (R) extending coaxially to said longitudinal axis (21′), and
• wherein said temporary holding system (1) comprises rotating rotational operation means (9), suitable to rotate said sleeve (2), comprising said primary section (2a) and said secondary section (2b), according to a rotation movement about said axis of rotation (R).
