Jetty

A jetty is a marine structure projecting from the shore that gives berthing access over deep water without a continuous filled quay. An open or piled jetty carries a deck on piles, often a narrow loading platform served by a trestle, with breasting and mooring dolphins handling berthing and restraint at oil, LNG, and bulk terminals. A solid jetty acts as a quay wall or breakwater. The piled form lets waves and current pass under the deck, reducing wave load and littoral-drift disruption compared with a solid mole. Deck, piles, trestle, and fendering are designed to BS 6349-2 with PIANC berthing and mooring guidance.
