Energy absorption arrangement for reducing peak mooring loads

An energy absorption arrangement for reducing peak mooring loads between a mooring structure with a turret rotatable around a vertical axis (Z), and a floating structure, wherein the energy absorption arrangement;

• comprises:
• a rigid yoke horizontally rotatable in two axes (X, Y) and connected to the turret
• a weighted pendulum member arranged on an end of the rigid yoke and
• at least one mooring tether connected to the weighted pendulum member, and
• at least one energy absorption device for reducing peak mooring loads, comprising a fixed part connected to the floating structure, a movable rod having an outer end, and an absorption medium,
• wherein a mooring loads up to a first predetermined load (F1) absorbed by the weighted pendulum, and mooring loads higher than the first predetermined load (F1) are absorbed by the at least one energy absorption device,
• wherein the outer end of the movable rod is connected to the at least one mooring tether, and the movable rod has an initial first length (X1) when exposed to a mooring load up to the first load (F1), and is extended a second length (X2) when exposed to a second load (F2) greater than the first load (F1) and the second length (X2) is longer than the first length (X1), and
• the at least one energy absorption device exerts a restoring force opposite of the first load (F1) and second load (F2), causing the movable rod to retract from its second length (X2) to its first length (X1) when the mooring loads decrease from the second load (F2) to the first load (F1).
