Navy Lighterage Pontoon
The Navy Lighterage pontoon (NLP) was a type of Float (nautical), pontoon developed in World War II by Capt. John N. Laycock Civil Engineer Corps (CEC) and used by United States Navy Construction Battalions(Seabee (US Navy), Seabees) on invasion beaches and shallow harbors or harbors where the facilities had been destroyed or did not exist. It was referred to as the Seabee's "magic box". It was Lego-like system of pre-cut pre-drilled angle iron and steel plate. It was first assembled into individual boxes that were joined in multiples to construct Dock (maritime), docks, causeways, rhinos, barges, dry docks, crane vessel, floating cranes, marine railways or whatever was needed. Capt. Carl A. Carlson CEC of the War Plans Office came up with the concept of NLPs in 1935,Captain John N.

Capt
Captain is a title, an appellative for the commanding officer of a military unit; the supreme leader of a navy ship, merchant ship, aeroplane, spacecraft, or other vessel; or the commander of a port, fire or police department, election precinct, etc. In militaries, the captain is typically at the level of an officer commanding a company or battalion of infantry, a ship, or a battery of artillery, or another distinct unit.

Marine Railway
The patent slip or marine railway is an inclined plane extending from shoreline into water, featuring a "cradle" onto which a ship is first floated, and a mechanism to haul the ship, attached to the cradle, out of the water onto a slip. The marine railway was invented by a Scot, Thomas Morton, in the early 19th century, as a cheaper alternative to dry docks for marine vessel repairs, in particular below waterline. Larger modern marine railways can handle vessels of thousands of tons. History Invented by shipwright Thomas Morton in 1818, the marine railway offered an alternative to the expensive and time-consuming process of dry docking a ship to perform maintenance or repairs to its hull below waterline. The means and mechanisms over time became various, but always include a "cradle" onto which the ship is floated, and a mechanical mechanism for transferring the ship from water to land up an incline. The destination where work was performed was termed the slip. Thomas Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
