SS India Arrow
SS ''India Arrow'' was a steam built in 1921 by Bethlehem Shipbuilding Corporation of Quincy, Massachusetts for Standard Oil Co., with intention of transporting oil and petroleum products between the United States and the Far East. During the first eight years the tanker was chiefly employed in the Pacific trade, carrying cargo between Gulf ports and a variety of destinations in East Asia. In late 1920s the tanker was moved to serve intercoastal trade routes while still making occasional trips to Asia. In early 1930s she was permanently assigned to trade routes between the Gulf and the ports on the United States East Coast, where she remained for the rest of her career. ''India Arrow'' was torpedoed and sunk by the in February 1942 during one of her routine trips from Texas to New York. Twenty-six of her crew died as a result. Design and construction Early in 1919, Standard Oil Co. decided to add four more tankers of approximately 12,500 deadweight tonnage to its existing flee ...

Ship Sponsor
A ship sponsor, by tradition, is a female civilian who is invited to "sponsor" a vessel, presumably to bestow good luck and divine protection over the seagoing vessel and all that sail aboard.Eyers, Jonathan (2011). ''Don't Shoot the Albatross!: Nautical Myths and Superstitions''. A&C Black, London, UK. . In the United States Navy and the United States Coast Guard, the sponsor is technically considered a permanent member of the ship's crew and is expected to give a part of her personality to the ship, as well as advocate for its continued service and well-being. For passenger ships the sponsor is called a godmother if the sponsor is female, or a godfather if the sponsor is male.

Massachusetts Bay
Massachusetts Bay is a bay on the Gulf of Maine that forms part of the central coastline of Massachusetts. Description The bay extends from Cape Ann on the north to Plymouth Harbor on the south, a distance of about . Its northern and southern shores incline toward each other through the entrance to Boston Harbor, where they are about five miles apart. The depth from the base of the triangle to Boston Harbor is about . The westmost point of the bay is at the city of Boston. The northern shore of Massachusetts Bay is rocky and irregular, but the southern shore is low, marshy, and sandy. Along the shores are a number of capes and headlands, and off the coast a number of small islands, especially in the entrance to Boston Harbor. The principal inlets are: on the north coast, Gloucester Harbor, Nahant Bay, Salem Harbor, Marblehead Harbor, and Lynn Harbor, and on the west, Boston Harbor, Dorchester Bay, and Quincy Bay (the two latter being part of the Outer Boston Harbor ...

Scotch Marine Boiler
A "Scotch" marine boiler (or simply Scotch boiler) is a design of steam boiler best known for its use on ships. The general layout is that of a short horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes. Gases and smoke from the furnace pass to the back of the boiler, then return through the small tubes and up and out of the chimney. The ends of these multiple tubes are capped by a smokebox, outside the boiler shell. The Scotch boiler is a fire-tube boiler, in that hot flue gases pass through tubes set within a tank of water. As such, it is a descendant of the earlier Lancashire boiler, and like the Lancashire it uses multiple separate furnaces to give greater heating area for a given furnace capacity. It differs from the Lancashire in two respects: many small-diameter tubes (typically diameter each) are used to increase the ratio of heating area to cross-section. Secondly, the ove ...

Lloyd's Register
Lloyd's Register Group Limited, trading as Lloyd's Register (LR), is a technical and professional services organisation and a maritime classification society, wholly owned by the Lloyd’s Register Foundation, a UK charity dedicated to research and education in science and engineering. The organisation dates to 1760. Its stated aims are to enhance the safety of life, property, and the environment, by helping its clients (including by validation, certification, and accreditation) to improve the safety and performance of complex projects, supply chains and critical infrastructure. In July 2012, the organisation converted from an industrial and provident society to a company limited by shares, named Lloyd’s Register Group Limited, with the new Lloyd’s Register Foundation as the sole shareholder. At the same time the organisation gave to the Foundation a substantial bond and equity portfolio to assist it with its charitable purposes. It will benefit from continued funding from ...

Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length, along with bore diameter, determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about , and the metric horsepower as in "cv" or "PS" which is approximately . The electric horsepower "hpE" is exactly , while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other power-generating machinery such as piston engines, turbines, and electric motors. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship’s carrying capacity, as it excluded the small, often unusable volume contained in its overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to ...

Longitudinal Framing
Longitudinal framing (also called the Isherwood system after Great Britain, British naval architect Sir Joseph Isherwood, who patented it in 1906) is a method of ship construction in which large, widely spaced Transverse framing, transverse frames are used in conjunction with light, closely spaced longitudinal members. This method, Isherwood felt, lent a ship much greater longitudinal strength than in ships built in the traditional method, where a series of closely spaced transverse frames are fitted from the keel to the sheer line, with corresponding deck beams, a method that is well suited to support longitudinal planking. Longitudinal framing was a known method of shipbuilding before Isherwood. Naval engineer John Scott Russell, J. Scott Russell, for instance, had built several longitudinally framed ships, including the SS Great Eastern, SS ''Great Eastern''. However, no one had made the process practical from a commercial standpoint, which was Isherwood's achievement. The fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
