Shiplift. A shiplift is a modern alternative for a slipway, a floating dry dock or a graving dry dock. A shiplift is used to dry dock and launch ships. It consists of a structural platform that is lifted and lowered exactly vertically, synchronously by a number of hoists. First, the platform is lowered underwater, then the ship is floated above ...
The ship lift can lift ships of up to 3,000 tons. [16] [122] The vertical distance traveled is 113 m (371 ft), [123] and the size of the ship lift's basin is 120 m × 18 m × 3.5 m (394 ft × 59 ft × 11 ft). The ship lift takes 30 to 40 minutes to transit, as opposed to the three to four hours for stepping through the locks. [124]
Lift-on/lift-off. Lift-on/lift-off (LoLo, sometimes LOLO, LO/LO or Lo/Lo) [1] ships are cargo ships with on-board cranes to load and unload cargo. Ships with cranes or other cargo handling equipment on-board are also termed geared vessels. As container ships usually have no on-board cranes or other mechanism to load or unload their cargo, they ...
A boat lift, ship lift, or lift lock is a machine for transporting boats between water at two different elevations, and is an alternative to the canal lock. It may be vertically moving, like the Anderton boat lift in England, rotational, like the Falkirk Wheel in Scotland, or operate on an inclined plane, like the Ronquières inclined plane in ...
Semi-submersible platform. A semi-submersible platform is a specialised marine vessel used in offshore roles including as offshore drilling rigs, safety vessels, oil production platforms, and heavy lift cranes. They have good ship stability and seakeeping, better than drillships. [1]
Naval architecture. Naval architecture, or naval engineering, is an engineering discipline incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation of marine vessels and structures. [1][2] Naval architecture involves basic ...
A liftboat is a self-propelled, self-elevating vessel used in support of various offshore mineral exploration and production or offshore construction activities. A liftboat has a relatively large open deck to accommodate equipment and supplies, and the capability of raising its hull clear of the water on its own legs so as to provide a stable ...
RP FLIP. R/P FLIP (floating instrument platform) is an open ocean research platform [5][6] that was owned by the U.S. Office of Naval Research (ONR) and operated by the Scripps Institution of Oceanography. [7] The platform is 108 meters (355 ft) long and is designed to partially flood and pitch backward 90°, resulting in only the front 17 ...
