A load absorber dampens relative movement between subsea bodies. The load absorber is cooperable with an actuating member such as a male piston element or a female cup on an opposed subsea body. The load absorber comprises a hollow structure defining an internal flow path for water. A flow restrictor acting on the flow path restricts a distal flow of water along the flow path from a proximal opening, caused by convergence between the actuating member and the load absorber. The flow restrictor comprises a shuttle element to restrict the flow path that is mounted to the structure for automatic movement from a first state to a second state in response to an increase in water pressure at the proximal opening. In the first state, the shuttle element effects greater restriction of the flow path than in the second state.
