Using a marine railway/patent slip avoids the need to pump out a dry dock, saving time and money. [4] In addition, a marine railway can substitute for a traditional waterway lock in areas where the terrain is poorly suited to an installation of that kind. This would consist of a railway where two ends each access a body of water, with a dry ...
Initially a linkspan was a ramp that was attached to the pier at one end and was suspended above the water at the other. The height above the water was controlled either by hydraulic rams or cables, these types of linkspans were less well designed for the various conditions of the tide, wave and current and so were superseded by underwater tank linkspans that through compressed air can be ...
Tug-propelled Dartmouth ferry barge with integral ramp at each end BC Ferries Dock seen from the ship about to dock. A ferry slip is a specialized docking facility that receives a ferryboat or train ferry. A similar structure called a barge slip receives a barge or car float that is used to carry wheeled vehicles across a body of water.
A slipway, also known as boat ramp or launch or boat deployer, is a ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage .
One shiplift can serve many parking places, while a dry docking installation can only dock one ship. Ship on a transfer system on a shiplift. For large vessels the transfer system consists of a number of trolleys or cradles, supported by high capacity steel wheels. The wheels drive on heavy duty rails.
Custom-built ferries were to be built, with railway lines and matching harbour facilities at both ends to allow the rolling stock to easily drive on and off the boat. [9] To compensate for the changing tides , adjustable ramps were positioned at the harbours and the gantry structure height was varied by moving it along the slipway.
A sailboat's mast is supported by shrouds (side-to-side) and stays (fore-and-aft) – nautical equivalents of guy wires.. A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure.
Trouble started when a two-inch cable parted at the Sampson braid and the Terminator had to approach the Dock Express 20. It was now a little after 6 pm in deepening twilight (sunset was 5:31 pm). Shortly after completing her approach to 100–150 feet (30–50 m) abeam of the Dock Express 20, Terminator lost the use of the center engine. The ...
