The Bludworth articulated tug and barge (ATB) ocean tug barge connection system was developed by Richard and Robert Bludworth during the 1960s.
The first Bludworth articulated tug barge unit was the ocean Liquefied petroleum gas (LPG) barge Ponciana which was coupled with the converted ATB tug Texan in 1970. Texan sank off Cape Hatteras in 1979. Ponciana is still a working ocean LPG barge coupled with the 1980-built tug Texan.
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours.
ATB is the stagename of André Tanneberger,, a German DJ, musician, and producer of Trance music.

An articulated vehicle is a vehicle which has a permanent or semi-permanent pivot joint in its construction, allowing it to turn more sharply. There are many kinds, from heavy equipment to buses, trams and trains. Steam locomotives were sometimes articulated so driving wheels could pivot around corners.

The SS St. Marys Challenger is a freight-carrying vessel operating on the North American Great Lakes built in 1906. Originally an ore boat, she spent most of her career as a cement carrier when much larger ore boats became common. After a 107-year-long working career as a self-propelled boat, she was converted into a barge and paired with the tug Prentiss Brown as an articulated tug-barge. Before conversion, she was the oldest operating self-propelled lake freighter on the Great Lakes, as well as being one of the last freight-carrying vessels on the Great Lakes to be powered by steam engines.
Seaforth Channel is a channel in the Central Coast region of the Canadian province of British Columbia which is part of the Inside Passage - the 950 miles (1,530 km) passage between Seattle, Washington and Juneau, Alaska. The marine highway goes through Seaforth Channel on the way to Milbanke Sound, one of the open sea portions of the Inland Passage. Seaforth Channel which is part of the Prince Rupert/Port Hardy BC ferry route, extends in a westerly direction from Denny Island to Milbanke Sound between Denny Island, Campbell Island and the Wright group of islands on the south. In October 2016, a Texas-owned tug/barge transiting the Canadian waters of the Inside Passage without a local pilot was hard grounded on a reef at the entrance to Seaforth Channel in October 2016. More than 100,000 L of fuel contaminated the coast, coves and shores 20 km (12 mi) west of Bella Bella, the core community of the Heiltsuk Nation as well as the environmentally sensitive Great Bear Rainforest - Canada's contribution to the Queen's Commonwealth Canopy (QCC), a network of forest conservation programs. Clean up response and salvage was criticized by the Heiltsuk, B.C. Premier Christy Clark and Prime Minister Justin Trudeau. In November in Vancouver the Prime Minister announced a $1.5B ocean protection plan to "create a marine safety system, restore marine ecosystems and undertake research into oil spill cleanup methods."
The Type V ship is a United States Maritime Commission (MARCOM) designation for World War II tugboats. Type V was used in World War II, Korean War, and the Vietnam War. Type V ships were used to move ships and barges. Type V tugboats were made of either steel or wood hulls. There were four types of tugboats ordered for World War II. The largest type V design was the sea worthy 186-foot (57 m) long steel hull, V4-M-A1. The V4-M-A1 design was used by a number of manufacturers; a total of 49 were built. A smaller steel hull tugboat was the 94-foot (29 m) V2-ME-A1; 26 were built. The largest wooden hull was the 148-foot (45 m) V3-S-AH2, of which 14 were built. The smaller wooden hull was the 58-foot (18 m) V2-M-AL1, which 35 were built. Most V2-M-AL1 tugboats were sent to the United Kingdom for the war efforts under the lend-lease act. The Type V tugs served across the globe during World War II including: Pacific War, European theatre, and in the United States. SS Farallon, and other Type V tugs, were used to help built Normandy ports, including Mulberry harbour, on D-Day, 6 June 1944, and made nine round trips to Normandy to deliver Phoenix breakwaters.
