Floating dock (jetty)
A floating dock, floating pier or floating jetty is a platform or ramp supported by pontoons. It is usually joined to the shore with a gangway. The pier is usually held in place by vertical poles referred to as pilings, which are embedded in the seafloor or by anchored cables.
In shipbuilding and ship operations the term floating dock refers to a floating drydock.
