18. A method of levelling and gripping a jacket leg extending along a longitudinal axis, the method comprising:

adjusting, by a levelling assembly, a direction of the longitudinal axis of the jacket leg when the jacket leg is partially inserted into a hollow foundation pile;

for each of a plurality of wedges, inserting, by an actuator for that wedge, that wedge into a clearance between the hollow foundation pile and the jacket leg;

retaining, by a restraining member arranged around the actuator, the actuator parallel to the longitudinal axis; and

at least partially dismounting the levelling assembly from the jacket leg.
