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 ...
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 ...
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 ...
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]
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 ...
Heavy lift. In transportation, heavy lift refers to the handling and installation of heavy items which are indivisible, and of weights generally accepted to be over 100 tons and of widths/heights of more than 100 meters. These oversized items are transported from one place to another (sometimes across country borders), then lifted or installed ...
The platform of the lift moves along the rack railway, with the track gauge of 9 m. The movement is carried out by means of electric drive. In order to load the ship lift, the platform is lowered below the water level, at which point the ship then enters the lift, and the platform begins to move up the overpass. The ships are transported afloat.
A heavy-lift ship is a vessel designed to move very large loads that cannot be transported by normal ships. They are of two types: They are of two types: Semi-submersible ships that take on water ballast to allow the load—usually another vessel—to be floated over the deck, whereupon the ballast is jettisoned and the ship's deck and cargo ...
