Elastic dolphins are usually composed of piles driven in vertical position; amount of energy dolphin is able to absorb can be considerably increased if dolphin is held deflected to side from which blow of vessel is expected, which can be done by driving piles at an angle with vertical and keeping them stressed under weight of concrete blocks; any desired amount of prestressing can be achieved through choice of slope and block weight; unit can be used only where direction of vessel impact is known; diagrams.
