A load absorber 30, mounted in use on a subsea body 20, is cooperable with an actuating member 32 such as a male piston element or a female cup on an opposed subsea body 18. The load absorber comprises a hollow structure defining an internal flow path 48, 50, 52, 54 for water. A flow restrictor acting on the flow path restricts a distal flow of water along the flow path from a proximal opening 46, caused by convergence between the actuating member and the load absorber. The flow restrictor comprises a shuttle element 68 to restrict the flow path that is mounted to the structure for automatic movement from a first state to a second state (Fig 5) in response to an increase in water pressure at the proximal opening. In the first state, the shuttle element may effect greater restriction of the flow path than in the second state. A method of using the load absorber is also disclosed. |
