The line was established by the ''Nederlandsche Stoomboot Maatschappij'' (known as NSM and in English as Netherlands Steamship Company).Greenway (1986), p.101 History Having attempted unsuccessfully to establish services between Rotterdam–Hamburg and Antwerp–London, the company turned its attention to Rotterdam–London and became the first regular foreign-owned company to set up such a service into London Port.

Submarine Snorkel
A submarine snorkel is a device which allows the engine of a submarine to operate Underwater, submerged while still taking in air from above the surface. British Royal Navy personnel often refer to it as the snort. A concept devised by Dutch engineers, it was widely used on German U-boats during the last year of World War II and known to them as a . History Until the advent of Nuclear submarine, nuclear power, submarines were designed to operate on the surface most of the time and submerge only for evasion or for daylight attacks. Until the widespread use of radar after 1940, at night a submarine was safer on the surface than submerged, because sonar could detect boats underwater but was almost useless against a surface vessel. However, with continued radar improvement as the war progressed, submarines (notably, the Germany, German U-boat, U-boats in the Battle of the Atlantic) were forced to spend more time underwater, running on electric motors that gave speeds of only a fe ...

Floating Sheerleg
A floating sheerleg (also: shearleg) is a floating water vessel with a Crane (machine), crane built on shear legs. Unlike other types of crane vessel, it is not capable of rotating its crane independently of its hull. There is a huge variety in sheerleg capacity. The smaller cranes start at around 50 tons in lifting capacity, with the largest being able to lift 20,000 tons. The bigger sheerlegs usually have their own propulsion system and have a large accommodation facility on board, while smaller units are floating Pontoon (boat), pontoons that need to be towed to their workplace by tugboats. Sheerlegs are commonly used for Marine salvage, salvaging ships, assistance in shipbuilding, Stevedore, loading and unloading large cargo into ships, and bridge building. They have grown considerably larger over the last decades due to a marked increase in vessel, cargo, and component size (of ships, offshore oil rigs, and other large fabrications), resulting in heavier lifts both during c ...

Planer (metalworking)
A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to cut the work piece.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' p. 73, Cypress, CA, 2013. . A planer is similar to a shaper, but larger, and with workpiece moving, whereas in a shaper the cutting tool moves. Applications Linear planing The most common applications of planers and shapers are linear-toolpath ones, such as: * Generating accurate flat surfaces. (While not as precise as grinding, a planer can remove a tremendous amount of material in one pass with high accuracy.) * Cutting slots (such as keyways). * It is even possible to do work that might now be done by wire EDM in some cases. Starting from a drilled or cored hole, a planer with a boring-bar type tool can cut internal features that do not lend themselves to milling or boring (such as irregularly shaped holes with tig ...
