65-549: MV Nova Star is a Ropax cruiseferry , currently operating between Poland and Scandinavia under the ownership of Polferries . The vessel was built by ST Marine in Singapore for LD Lines , which signed a $ 179 million contract for the vessel in 2007. She was intended to operate in the English Channel , but her contract was canceled in 2011 before she could take her maiden voyage to France . Initially named Norman Leader ,
130-547: A 1966 Toyota Corona , the first mass-produced car to be shipped in specialised car-carriers and used as the basis of RORO vessel size. 1 RT is approximately 4m of lane space required to store a 1.5m wide Toyota Corona) or in car-equivalent units ( CEU ). The largest RORO passenger ferry is MS Color Magic , a 75,100 GT cruise ferry that entered service in September 2007 for Color Line . Built in Finland by Aker Finnyards , it
195-557: A calculation of the volume or cargo volume of a ship. Although tonnage (volume) should not be confused with displacement (the actual mass of the vessel), the long ton (or imperial ton) of 2,240 lb is derived from the fact that a " tun " of wine typically weighed that much. Tonnage measurements are governed by an IMO Convention (International Convention on Tonnage Measurement of Ships, 1969 (London-Rules)), which initially applied to all ships built after July 1982, and to older ships from July 1994. A commonly defined measurement system
260-516: A formula based on the vessel's length and beam. Historically in England , tunnage was the medieval import duty on tuns of wine. A tun was a large size of casks used for wine ), used in the wine trade. The number of tuns that a ship could carry was used as a measure of the size of the ship. The wine trade to England originated in France, which is where the tuns were made. A French standard tun cask size
325-463: A high priority was assigned to the construction of LSTs that the previously laid keel of an aircraft carrier was hastily removed to make room for several LSTs to be built in her place. The keel of the first LST was laid down on 10 June 1942 at Newport News, Virginia , and the first standardized LSTs were floated out of their building dock in October. Twenty-three were in commission by the end of 1942. At

It is still in use, as amended by the Rules of Navigation of the Suez Canal Authority and is registered in the Suez Canal Tonnage Certificate. Thames measurement tonnage (TM) is another volumetric system, generally used for small vessels such as yachts ; it uses
455-513: A partner of the firm Grainger and Miller. The service commenced on 3 February 1850. It was called "The Floating Railway" and intended as a temporary measure until the railway could build a bridge, but this was not opened until 1890 , its construction delayed in part by repercussions from the catastrophic failure of Thomas Bouch's Tay Rail Bridge . Train-ferry services were used extensively during World War I . From 10 February 1918, high volumes of railway rolling stock, artillery and supplies for
520-526: A passenger certificate, and was allowed to carry fifty passengers. Thus Empire Cedric became the first vessel in the world to operate as a commercial/passenger roll-on/roll-off ferry, and the ASN became the first commercial company to offer this type of service. The first RORO service crossing the English Channel began from Dover in 1953. In 1954, the British Transport Commission (BTC) took over
585-800: A second train-ferry was established from the Port of Southampton on the South East Coast. In the first month of operations at Richborough, 5,000 tons were transported across the Channel, by the end of 1918 it was nearly 261,000 tons. There were many advantages of the use of train-ferries over conventional shipping in World War I. It was much easier to move the large, heavy artillery and tanks that this kind of modern warfare required using train-ferries as opposed to repeated loading and unloading of cargo. By manufacturers loading tanks, guns and other heavy items for shipping to
650-530: A smaller size of standard barrel. This was the barrique bordelaise , measuring a quarter of the size of the tun (in English, this barrel was termed a hogshead ). For instance, Basque ships engaged in 16th century whaling in Labrador used this size of barrel (with the name barrica ). The French tonneau de mer was legally defined, in 1681, as the cubic space into which four barrique bordelaise fitted, with
715-401: A stern ramp as well as interior ramps, which allowed cars to drive directly from the dock, onto the ship, and into place. Loading and unloading was sped up dramatically. Comet also had an adjustable chocking system for locking cars onto the decks and a ventilation system to remove exhaust gases that accumulate during vehicle loading. During the 1982 Falklands War , SS Atlantic Conveyor

#1732852550707780-475: A vessel 300 ft (91 m) long a "craft" was considered a misnomer and the type was re-christened "Landing Ship, Tank (2)", or "LST (2)". The LST(2) design incorporated elements of the first British LCTs from their designer, Sir Rowland Baker, who was part of the British delegation. This included sufficient buoyancy in the ships' sidewalls that they would float even with the tank deck flooded. The LST(2) gave up
845-407: A volume that, if filled with fresh water, would weigh around 2.83 tonnes . The definition and calculation of the internal volume is complex; for instance, a ship's hold may be assessed for bulk grain (accounting for all the air space in the hold) or for bales (omitting the spaces into which bulk, but not baled cargo, would spill). Gross register tonnage was replaced by gross tonnage in 1982 under
910-504: Is 209.02 m (685 ft 9 in) long and 31.84 m (104 ft 6 in) wide, and can carry 1,342 cars/4,101 lane meters of cargo. The first cargo ships specially fitted for the transport of large quantities of cars came into service in the early 1960s. These ships still had their own loading gear and so-called hanging decks inside. They were, for example, chartered by the German Volkswagen AG to transport vehicles to
975-405: Is 223.70 m (733 ft 11 in) long and 35 m (114 ft 10 in) wide, and can carry 550 cars, or 1,270 lane meters of cargo. The RORO passenger ferry with the greatest car-carrying capacity is Ulysses (named after a novel by James Joyce ), owned by Irish Ferries . Ulysses entered service on 25 March 2001 and operates between Dublin and Holyhead . The 50,938 GT ship
1040-399: Is a function of the moulded volume of all cargo spaces of the ship. The Panama Canal/Universal Measurement System (PC/UMS) is based on net tonnage modified for Panama Canal purposes. PC/UMS is based on a mathematical formula to calculate a vessel's total volume; one PC/UMS net ton is equivalent to 100 cubic feet (2.83 m ) of capacity. The Suez Canal Net Tonnage (SCNT) is derived with
1105-781: Is capable of a top speed of 21 kn (39 km/h), and weighs roughly 27,450 GT. The ship features a large variety of cruise-ship like features, including two restaurants, three bars, a casino gaming facility, and a duty-free retail shop. The ship also includes a children play area, live on-board entertainment, a spa and art gallery. The vessel has 163 cabins and a capacity of 1,215 passengers. She can carry 336 car-equivalents and/or 38 commercial vehicles (semi-trailer rigs or buses) and commensurately fewer cars. Ropax Roll-on/roll-off ( RORO or ro-ro ) ships are cargo ships designed to carry wheeled cargo , such as cars , motorcycles , trucks , semi-trailer trucks , buses , trailers , and railroad cars , that are driven on and off
1170-508: Is developing a new vessel class with a capacity of 12,800 CEU. The design has received Approval in Principle (AiP) from Lloyd's Register , which was granted in June 2024. The car carrier Auriga Leader , belonging to Nippon Yusen Kaisha, built in 2008 with a capacity of 6,200 cars, is the world's first partially solar powered ship. The seagoing RORO car ferry, with large external doors close to
1235-443: Is important, since a ship's registration fee, harbour dues, safety and manning rules, and the like may be based on its gross tonnage (GT) or net tonnage (NT). Gross tonnage (GT) is a function of the volume of all of a ship's enclosed spaces (from keel to funnel ) measured to the outside of the hull framing. The numerical value for a ship's GT is always smaller than the numerical values of gross register tonnage (GRT). Gross tonnage
1300-596: Is just over 40 cubic feet (1.1 m ). British practice by the 19th century was for a ton of cargo volume to be 50 cubic feet (1.4 m ). This is derived from an estimate of the hull space needed to fit the roughly cylindrical tun and is broadly consistent with the much earlier French definition given below. The Bordeaux tun was used as a measurement elsewhere in Europe. By the 16th century, multi-decked ships which were loaded through hatchways (as opposed to earlier undecked or single decked ships) found it more convenient to use
1365-413: Is therefore a kind of capacity-derived index that is used to rank a ship for purposes of determining manning, safety, and other statutory requirements and is expressed simply as GT, which is a unitless entity, even though it derives from the volumetric capacity in cubic metres. Net tonnage (NT) is based on a calculation of the volume of all cargo spaces of the ship. It indicates a vessel's earning space and

#17328525507071430-462: The Middle Ages , ships were often impressed by the crown for military use. To do this in an efficient and speedy manner, a measurement of size was needed. The payment to the owner of the requisitioned ship was based on the tonnage. Port dues and various licences were based on tonnage, and it was a useful measure for a ship builder who needed to build a vessel that met the new owner's requirements. In
1495-474: The Tudor period a bounty per ton was paid for the construction of larger ships, so the threshold for that payment had to be determined, as well as the amount paid for those qualifying. In the middle ages, the normal way of discovering the tonnage of a ship was to load her with wine and see how many tuns could be fitted in. There is an instance of the owner of a new ship, in 1459, being challenged that his safe-conduct
1560-560: The 2015 season, Nova Star Cruises subsequently closed and Gulf of Maine operations were taken over by Bay Ferries , which has previously operated ferries in the region prior to Nova Star Cruises. Once her Gulf of Maine service ended, Nova Star was purchased by the Moroccan company Inter Shipping. Following her arrival in Algeciras in February 2016, it was made apparent that Nova Star' s bow ramp
1625-462: The ASN under the Labour Governments nationalization policy. In 1955 another two LSTs where chartered into the existing fleet, Empire Cymric and Empire Nordic , bringing the fleet strength to seven. The Hamburg service was terminated in 1955, and a new service was opened between Antwerp and Tilbury. The fleet of seven ships was to be split up with the usual three ships based at Tilbury and
1690-463: The ASN were able to convince commercial operators to support the new route between Preston and the Northern Ireland port of Larne . The first sailing of this new route was on 21 May 1948 by Empire Cedric . After the inaugural sailing Empire Cedric continued on the Northern Ireland service, offering initially a twice-weekly service. Empire Cedric was the first vessel of the ASN fleet to hold
1755-522: The Front were shipped to France from the "secret port" of Richborough , near Sandwich on the South Coast of England. This involved three train-ferries to be built, each with four sets of railway line on the main deck to allow for up to 54 railway wagons to be shunted directly on and off the ferry. These train-ferries could also be used to transport motor vehicles along with railway rolling stock. Later that month
1820-566: The Tonnage Measurement convention of 1969, with all ships measured in GRT either scrapped or re-measured in GT by 1994. Net register tonnage (NRT) is the volume of cargo the vessel can carry—that is, the gross register tonnage less the volume of spaces that do not hold cargo (e.g., engine compartment, helm station, and crew spaces, again with differences depending on which port or country does
1885-545: The U.S. and Canada. During the 1970s, the market for exporting and importing cars increased dramatically and correspondingly also did the number and type of ROROs . In 1970 Japan's K Line built the Toyota Maru No. 10 , Japan's first pure car carrier, and in 1973 built the European Highway , the largest pure car carrier (PCC) at that time, which carried 4,200 automobiles. Today's pure car carriers and their close cousins,

The difference between this measure and, for instance, the Spanish toneladas was calculated by recognised adjustment factors. Tonnage measurement was important for an increasing number of reasons through history. In England in

As a result, each of the three ( Boxer , Bruiser , and Thruster ) ordered in March 1941 had a very long ramp stowed behind the bow doors. In November 1941, a small delegation from the British Admiralty arrived in the United States to pool ideas with the United States Navy 's Bureau of Ships with regard to development of ships and also including
2145-409: The end of the first world war vehicles were brought back from France to Richborough Port drive-on-drive-off using the train ferry. During the war British servicemen recognised the great potential of landing ships and craft. The idea was simple; if you could drive tanks, guns and lorries directly onto a ship and then drive them off at the other end directly onto a beach, then theoretically you could use
2210-518: The first purpose-built seagoing ships enabling road vehicles to roll directly on and off. The British evacuation from Dunkirk in 1940 demonstrated to the Admiralty that the Allies needed relatively large, seagoing ships capable of shore-to-shore delivery of tanks and other vehicles in amphibious assaults upon the continent of Europe. As an interim measure, three 4000 to 4800 GRT tankers, built to pass over

On the morning of 11 September 1946 the first voyage of the Atlantic Steam Navigation Company took place when Empire Baltic sailed from Tilbury to Rotterdam with a full load of 64 vehicles for the Dutch Government. The original three LSTs were joined in 1948 by another vessel, LST 3041 , renamed Empire Doric , after
2405-492: The observation that "there was little merit in a simple conception of this kind, compared with a work practically carried out in all its details, and brought to perfection." The company was persuaded to install this train ferry service for the transportation of goods wagons across the Firth of Forth from Burntisland in Fife to Granton . The ferry itself was built by Thomas Grainger ,
2470-626: The others maintaining the Preston to Northern Ireland service. During late 1956, the entire fleet of ASN were taken over for use in the Mediterranean during the Suez Crisis , and the drive-on/drive-off services were not re-established until January 1957. At this point ASN were made responsible for the management of twelve Admiralty LST(3)s brought out of reserve as a result of the Suez Crisis too late to see service. The first roll-on/roll-off vessel that
2535-655: The possibility of building further Boxer s in the US. During this meeting, it was decided that the Bureau of Ships would design these vessels. As with the standing agreement these would be built by the US so British shipyards could concentrate on building vessels for the Royal Navy . The specification called for vessels capable of crossing the Atlantic and the original title given to them was "Atlantic Tank Landing Craft" (Atlantic (T.L.C.)). Calling
2600-829: The pure car/truck carrier (PCTC), are distinctive ships with a box-like superstructure running the entire length and breadth of the hull, fully enclosing the cargo. They typically have a stern ramp and a side ramp for dual loading of thousands of vehicles (such as cars, trucks, heavy machineries, tracked units, Mafi roll trailers , and loose statics), and extensive automatic fire control systems. The PCTC has liftable decks to increase vertical clearance, as well as heavier decks for "high-and-heavy" cargo. A 6,500-unit car ship, with 12 decks, can have three decks which can take cargo up to 150 short tons (136 t ; 134 long tons ) with liftable panels to increase clearance from 1.7 to 6.7 m (5 ft 7 in to 22 ft 0 in) on some decks. Lifting decks to accommodate higher cargo reduces
2665-416: The restrictive bars of Lake Maracaibo , Venezuela , were selected for conversion because of their shallow draft. Bow doors and ramps were added to these ships, which became the first tank landing ships. The first purpose-built LST design was HMS Boxer .

From this idea grew the worldwide roll-on/roll-off ferry industry of today. In the period between the wars Lt. Colonel Frank Bustard formed the Atlantic Steam Navigation Company , with a view to cheap transatlantic travel; this never materialised, but during
2795-471: The ship on their own wheels or using a platform vehicle, such as a self-propelled modular transporter . This is in contrast to lift-on/lift-off (LoLo) vessels, which use a crane to load and unload cargo. RORO vessels have either built-in or shore-based ramps or ferry slips that allow the cargo to be efficiently rolled on and off the vessel when in port. While smaller ferries that operate across rivers and other short distances often have built-in ramps,
2860-699: The ship unstable and causing it to capsize . Free surface water on the vehicle deck was determined by the court of inquiry to be the immediate cause of the 1968 capsize of the TEV ; Wahine in New Zealand. It also contributed to the wreck of MS Estonia . Despite these inherent risks, the very high freeboard raises the seaworthiness of these vessels. For example, the car carrier MV Cougar Ace listed 60 degrees to its port side in 2006, but did not sink, since its high enclosed sides prevented water from entering. In late January 2016 MV Modern Express
2925-462: The shipping industry, cargo is normally measured by tonnage or by the tonne , but RORO cargo is typically measured in lanes in metres (LIMs). This is calculated by multiplying the cargo length in metres by the number of decks and by its width in lanes (lane width differs from vessel to vessel, and there are several industry standards). On PCCs, cargo capacity is often measured in RT or RT43 units (based on
2990-549: The signing of the Armistice on 11 November 1918, train ferries were used extensively for the return of material from the Front. Indeed, according to war office statistics, a greater tonnage of material was transported by train ferry from Richborough in 1919 than in 1918. As the train ferries had space for motor transport as well as railway rolling stock, thousands of lorries, motor cars and "B Type" buses used these ferries to return to England. During World War II , landing ships were

In three separate acts dated 6 February 1942, 26 May 1943, and 17 December 1943, Congress provided the authority for the construction of LSTs along with a host of other auxiliaries, destroyer escorts , and assorted landing craft . The enormous building program quickly gathered momentum. Such
3120-456: The term RORO is generally reserved for large seagoing vessels. The ramps and doors may be located in the stern , bow , or sides, or any combination thereof. Types of RORO vessels include ferries , cruiseferries , cargo ships , barges , and RoRo service for air/ railway deliveries. New automobiles that are transported by ship are often moved on a large type of RORO called a pure car carrier (PCC) or pure car/truck carrier (PCTC). Elsewhere in
3185-543: The total capacity. These vessels can achieve a cruising speed of 16 knots (18 mph; 30 km/h) at eco-speed, while at full speed can achieve more than 19 knots (22 mph; 35 km/h). As of 7 August 2024 , the largest LCTC was the Höegh Aurora , the inaugural vessel of a planned class of twelve, each with a capacity of 9,100 CEU. Meanwhile, the Marine Design & Research Institute of China (MARIC)
3250-426: The up-and-coming civil engineer Thomas Bouch who argued for a train ferry with a roll-on/roll-off mechanism to maximise the efficiency of the system. Ferries were to be custom-built, with railway lines and matching harbour facilities at both ends to allow the rolling stock to easily drive on and off. To compensate for the changing tides , adjustable ramps were positioned at the harbours and the gantry structure height
3315-524: The use of 1,500 labourers, whereas when using train-ferries that number decreased to around 100 labourers. This was of utmost importance, as by 1918, the British Railway companies were experiencing a severe shortage of labour with hundreds of thousands of skilled and unskilled labourers away fighting at the front. The increase of heavy traffic because of the war effort meant that economies and efficiency in transport had to be made wherever possible. After

In the spring of 1946 the company approached the Admiralty with a request to purchase three of these vessels. The Admiralty were unwilling to sell, but after negotiations agreed to let the ASN have the use of three vessels on bareboat charter at a rate of £13 6s 8d per day. These vessels were LSTs 3519 , 3534 , and 3512 . They were renamed Empire Baltic , Empire Cedric , and Empire Celtic , perpetuating
3510-470: The war, a concept called the shipborne containerized air-defense system (SCADS) proposed a modular system to quickly convert a large RORO into an emergency aircraft carrier with ski jump, fueling systems, radar, defensive missiles, munitions, crew quarters, and work spaces. The entire system could be installed in about 48 hours on a container ship or RORO, when needed for operations up to a month unsupplied. The system could quickly be removed and stored again when

An improperly secured loading door can cause a ship to take on water and sink, as happened in 1987 with MS Herald of Free Enterprise . Water sloshing on the vehicle deck can set up a free surface effect , making
3640-411: Was apparently paid without any measurement system to confirm the actual size. The presumption is that it was taken from the amount of cargo unloaded after the first voyage (which would be recorded in the customs records of the relevant port). Gross register tonnage (GRT) represents the total internal volume of a vessel, where one register ton is equal to a volume of 100 cubic feet (2.83 m );
3705-431: Was established about 1450. The 15th century Bordeaux wine tun was between 240 and 252 imperial gallons (1,090 and 1,150 L; 288 and 303 US gal). When measuring the tonnage of a ship, the approximately cylindrical cask would have air space around it when stowed in a ship. Therefore the volume of hold space required for several tuns was greater than the total of the capacity of those tuns. 252 imperial gallons
3770-403: Was for a 400 ton vessel, whilst he had already loaded more than 600 tons. The excuse was accepted that he had no idea of her tonnage until she was loaded. In another case, in 1456, a dispute over the actual tonnage of a ship had to be resolved by having coopers part load her with (presumably empty) barrels to estimate what she could carry. The Tudor bounty paid for the construction of larger ship
3835-461: Was formed in 1842 and the company wished to extend the East Coast Main Line further north to Dundee and Aberdeen . As bridge technology was not yet capable enough to provide adequate support for the crossing over the Firth of Forth , which was roughly five miles across, a different solution had to be found, primarily for the transport of goods, where efficiency was key. The company hired
3900-409: Was listing off France after cargo shifted on the ship. Salvage crews secured the vessel and it was hauled into the port of Bilbao, Spain. At first, wheeled vehicles carried as cargo on oceangoing ships were treated like any other cargo. Automobiles had their fuel tanks emptied and their batteries disconnected before being hoisted into the ship's hold, where they were chocked and secured. This process

An early roll-on/roll-off service was a train ferry , started in 1833 by the Monkland and Kirkintilloch Railway , which operated a wagon ferry on the Forth and Clyde Canal in Scotland . The first modern train ferry was Leviathan , built in 1849. The Edinburgh, Leith and Newhaven Railway
