List of T2-SE-A1 Tankers still in active service, Aug 2000. Glad to see there's still a few left! deadweight tonnage of 16,300 and a full load tonnage of 22,445.

Later, it was concluded the steel used in the war time construction had too high a sulfur content that turned the steel brittle at lower temperatures. Bigger but faster, they were 526 ft (160.3 m) in total length, displaced about 22,445 tons, and were rated at 10,600 tons gross with 16,300 DWT — yet they attained a top speed approaching 16 1⁄2 knots (30.6 km/h; 19.0 mph). These were commissioned as …

By far the most common variety of the T2-type tanker was the T2-SE-A1, another commercial design already being built in 1940 by the Sun Shipbuilding Company for Standard Oil Company of New Jersey. 25 of this design were ordered by the Maritime Commission, of which five became Navy oilers as the Chiwawa class. Of these, 481 were designated T2-SE-A1, 43 were classed as A2 and one was an A3. After Pearl Harbor, the United States Maritime Commission ordered this model built en masse to supply U.S. warships already in accelerated production, and provide for the fuel needs of US forces in Europe and the Pacific, as well as to replace the tanker tonnage being lost at an alarming rate to German U-boats. The ships' propulsion systems' electrical turbines were used to generate electricity for on-shore use, drawing on fuel from the ships' 150,000-barrel holds. the United States of America during World War II, by Leonard My father was a Merchant Mariner, sailing as an engineer in several vessels before, during, and after World War II. Example was USS Patuxent, a Kennebec-class oiler. One is probably the last surviving T2-SE-A1 in mostly original condition. [10] [11], In 1966, the US Army reactivated 11 T2 tankers and converted them into floating electrical power generation plants and deployed them to Vietnam. The T2 was based on two ships built in 1938-39 by Bethlehem Steel for Socony-Vacuum Oil Company, Mobilfuel and Mobilube, differing from the Mobil ships principally in the installation of more powerful engines for higher speed. The T2 design was formalized by the United States Maritime Commission as its medium-sized "National Defense tanker", a ship built for merchant service which could be militarized as a fleet auxiliary in time of war. The T2 tanker design is apparently rugged enough to last years in service. The T2-SE-A1s were the most numerous Maritime Commission standard tankers built during the war and constituted all but eleven of the T-2 tankers constructed.

A total of 525 T-2 tankers were built in U.S. shipyards between 1942 and 1945. 481 were built in extremely short production times by the Alabama Drydock and Shipbuilding Company of Mobile, Alabama, the Kaiser Company at their Swan Island Yard at Portland, Oregon, the Marinship Corp. of Sausalito, California, and the Sun Shipbuilding and Drydock Company of Chester, Pennsylvania. The first Navy commissioning was in 1942. could hold 117,400 Bbls of oil and 595,000 gal of gasoline.

However, the entire fleet had the same dimensions: 523.5 feet long by 68 feet in beam and 39 feet in depth. The record, however, was held by Marinship, which had Huntington Hills ready for sea trials in just 33 days.[9]. These four T2-SE-A1 ships are still in service after all these years. Press, Cambridge MD. This occurred after two T-2s, Pendleton and Fort Mercer, split in two off Cape Cod within hours of each other.

The record, however, was held by Marinship, which had the Huntington Hills ready for sea trials in just 33 days. This occurred after two T2s, Pendleton and Fort Mercer, split in two off Cape Cod within hours of each other.

Standard T2s were 501 ft 6 in (152.9 m) in total length, with a beam of 68 ft (20.7 m).

The T2 tanker, or T2, was an oil tanker constructed and produced in large quantities in the United States during World War II.

After Pearl Harbor, the United States Maritime Commission ordered this model built en masse to supply U.S. warships already in accelerated production. They were used to transport fuel oil, diesel fuel, gasoline and sometimes black oil-crude oil. Despite the confusing T3 designation, the T3-S-A1s built by Bethlehem Sparrows Point for Standard Oil of New Jersey were identical to the original T2s except for having less powerful engines of 7700 hp. The A3 variation was essentially an A2 built as a naval oiler from the start, rather than converted later as many A2s were. 481 were built in extremely short production times by the Alabama Drydock and Shipbuilding Company of Mobile, Alabama, the Kaiser Company at their Swan Island Yard at Portland, Oregon, the Marinship Corp. of Sausalito, California and the Sun Shipbuilding and Drydock Company of Chester, Pennsylvania. Armament: one single 5'/38 cal dual purpose gun mount, four single 3"/50 cal dual purpose gun mounts, four twin 40 mm AA gun mounts and twelve single 20 mm AA gun mounts. The … They were used to transport fuel oil, diesel fuel, gasoline and sometimes black oil-crude oil. Arthur Sawyer and W. H. Mitchell.

Twenty-five of this design were ordered by the Maritime Commission, of which five became Navy oilers as the Chiwawa class. Keystone Tankships company ordered five tankers in 1940 from Sun Shipbuilding & Drydock of Chester, Pennsylvania, based on the T2 but longer and with increased capacity; Marcom would designate this design T2-A. Keystone Tankships company ordered five tankers in 1940 from Sun Shipbuilding & Drydock of Chester, PA, based on the T2 but longer and with increased capacity; Marcom would designate this design T2-A. MarCom subsidized the excess cost of naval features beyond normal commercial standards. My father was a Merchant Seaman, sailing as an engineer in several vessels before, during, and after World War II. All five were requisitioned by the Navy during the war and converted to fleet oilers as the Mattaponi class. Powered by turbine engines rated at 12,000 hp (8,900 kW) with a top speed of 17.5 knots (32.4 km/h; 20.1 mph). It was found the steel (that had been successfully used in riveted ship design) was not well suited for the new wartime welding construction. As a lifelong student of maritime and naval history, I became interested in some ships of our merchant fleet. Rated at 9,900 tons gross (GRT), with 15,850 long tons deadweight (DWT), standard T2s displaced about 21,100 tons. Pendleton's sinking is memorialized in The Finest Hours. A United States Coast Guard Marine Board of Investigation in 1952 stated the ships were prone to splitting in two in cold weather and they were then "belted" with steel straps. The War Shipping Board requisitioned the last remaining T2 and T2-A tankers still in commercial service, Catawba and Aekay, and, with reservations given their limited speed, two nearly-complete Sun T2-SE-A1s, Harlem Heights and Valley Forge. They were 523 ft (159.4 m) long, 68 ft (20.7 m) abeam, with 10,448 gross register tons (GRT) and 16,613 DWT. Six were built for commerce by Bethlehem-Sparrows Point Shipyard in Maryland, only to be taken over by the United States Navy following the Attack on Pearl Harbor as the Kennebec-class oiler. Active T2 Tankers in August 2000. The largest "navy oilers" of the period, after the T3s, nearly 500 were built between 1940 and the end of 1945. Active T2 Tankers in August 2000. These ships have not been used in a number of years, and are layed up and likely to be scrapped in the next few years. This allowed the ships to produce electricity for two years without refueling for the Vietnam War. "The Conversion of T2 Tankers for Great Lakes and Seaway Service By M.

Only the T3 tankers were larger "navy oilers" of the period. Their design was developed by Sun Shipbuilding and Dry Dock Co. for Standard Oil and the first ships of this type were laid down in early 1940. The T2 design was formalized by the United States Maritime Commission as its medium-sized "National Defense tanker," a ship built for merchant service which could be militarized as a fleet auxiliary in time of war. Six were built for commerce by Bethlehem-Sparrows Point Shipyard in Maryland, only to be taken over by the United States Navy following the attack on Pearl Harbor as the Kennebec-class oiler. [1] Engineering inquiries into the problem suggested the cause was poor welding techniques.

The idea generation to build cargo vessels like the T2 tankers was adopted from a couple of oil cargo vessels built for a shipping conglomerate in the late 1930s. Steam turbines driving a single propeller at 12,000 horsepower (8,900 kW) delivered a top speed of 16 knots (30 km/h; 18 mph). Post war many T2s remained in use; like other hastily built World War II ships pressed into peacetime service, there were safety concerns. During that period, average production time from laying of the keel to "fitting out" was 70 days. The T2 was based on two ships built in 1938–1939 by Bethlehem Steel for Socony-Vacuum Oil Company, Mobilfuel and Mobilube, differing from the Mobil ships principally in the installation of more powerful engines for higher speed. "Report Tanker Fort Lee Sunk in Indian Ocean". "Victory" type cargo ships and of the Tankers built in The dimensions were: Length: 526 ft (160 m), Beam: 68 ft (21 m) and max. Steam turbines driving a single propeller at 12,000 horsepower (8,900 kW) delivered a top speed of 16 knots (30 km/h).

The T2-SE-A2 variation, built only by Marinship of Sausalito, was nearly identical to the T2-SE-A1 version, except with 10,000 hp (7,500 kW) rather than 7,240. They were 523 ft (159.4 m) long, 68 ft (20.7 m) abeam, with 10,448 gross register tons (GRT) and 16,613 DWT. Post war many T2s remained in use; like other hastily built World War II ships pressed into peacetime service, there were safety concerns.

Crew of 23 officers and 329 enlisted men. Although none is in original condition or configuration, all retain the classic T2 turbo electric propulsion, giving 7,240 shaft horsepower. MarCom subsidized the excess cost of naval features beyond normal commercial standards. As was found during the war, the United States Coast Guard Marine Board of Investigation in 1952 stated that in cold weather the ships were prone to metal fatigue cracking, so were "belted" with steel straps.

Despite the confusing T3 designation, the T3-S-A1s built by Bethlehem Sparrows Point for Standard Oil of New Jersey were identical to the original T2s except for having less powerful engines of 7,700 hp (5,700 kW). By far the most common variety of the T2-type tanker was the T2-SE-A1, another commercial design already being built in 1940 by the Sun Shipbuilding Company for Standard Oil Company of New Jersey. The high sulfur content made the steel brittle and prone to metal fatigue at lower temperatures.[2][3][4][5][6][7][8]. List of T2-SE-A1 Tankers still in active service, Aug 2000. The T2 design was formalized by the United States Maritime Commission as its medium-sized "National Defense tanker," a ship built for merchant service which could be militarized as a fleet auxiliary in time of war.
