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 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.
57-614: 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, 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
114-801: A MOU with KEPCO , Zodiac Maritime and KSOE to assess rule requirements for the safe operation and regulatory compliance of nuclear powered bulk carriers and container ships to be designed and built by the consortium . Lloyd's Register is known best for the classification and certification of ships and inspects and approves important components and accessories, including life-saving appliances, marine pollution prevention, fire protection, navigation, radio communication equipment, deck gear, cables, ropes, and anchors . LR's Rules for Ships LR's Rules for Ships are derived from principles of naval architecture and marine engineering , and govern safety and operational standards for numerous merchant, military, and privately owned vessels. LR's Rules govern
171-468: 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
228-471: A large type of RORO called a pure car carrier (PCC) or pure car/truck carrier (PCTC). Elsewhere in 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
285-446: A number of topics including: Specific editions of the rules are available to cater for merchant ships, naval ships, trimarans , special purpose vessels and offshore structures. A ship is known as being in class if she meets all the minimum requirements of LR's Rules , and such a status affects the possibility of a ship getting insurance. Class can be withdrawn from a ship if she is in violation of any regulations and does not maintain
342-604: 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
399-821: 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
456-422: A ship's load line survey – due once every five years. Such a survey includes an inspection of the hull to make sure that the load line has not been altered. Numerous other inspections such as the condition of hatch and door seals, safety barriers, and guard rails are also performed. Upon completion the ship is allowed to be operated for another year, and is issued a load line certificate. Lloyd’s Register provide
513-401: 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
570-479: 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
627-512: 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

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
741-504: 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 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
855-653: Is often measured in RT or RT43 units (based on 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
912-470: 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
969-471: 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
1026-532: 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
1083-560: 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,
1140-457: The best classification "A1", from which the expression A1 or A1 at Lloyd's is derived, first appeared in the 1775–76 edition of the Register. The Register, with information on all seagoing, self-propelled merchant ships of 100 gross tons or greater, is published annually. A vessel remains registered with Lloyd's Register until it is sunk, wrecked , hulked , scrapped or withdrawn from
1197-663: The conflict was over. The Soviets flying Yakovlev Yak-38 fighters also tested operations using the civilian RORO ships Agostinio Neto and Nikolai Cherkasov .

#17327800495461254-717: The crew) at a speed of 18 knots, it could not have the shallow draught that would have made for easy unloading. 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
1311-408: 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
1368-497: 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
1425-447: The first known register of its type. Between 1800 and 1833, a dispute between shipowners and underwriters resulted in each group publishing a list—the "Red Book" and the "Green Book" . Both parties came to the verge of bankruptcy. They reached agreement in 1834 to unite and form Lloyd’s Register of British and Foreign Shipping, establishing a General Committee and charitable values. In 1914, with an increasingly international outlook,
1482-527: 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
1539-595: The front directly on to railway wagons, which could be shunted on to a train-ferry in England and then shunted directly on to the French Railway Network, with direct connections to the Front Lines, many man hours of unnecessary labour were avoided. An analysis done at the time found that to transport 1,000 tons of war material from the point of manufacture to the front by conventional means involved

In 2022, LR acquired OneOcean Group, a marine software and digital services company, to head up a new digital services division. Lloyd's Register is unaffiliated with Lloyd's of London , but emerged from the same professional and social circles that historically met at Lloyd's Coffee House , from which both organisations took their name. The organisation

The latter developments are reflected, among other things, in the acquisition of Senergy, an integrated energy service provider, in 2013 and Nettitude, a cyber security specialist in 2018. Lloyd’s Register has built a portfolio of digital, data and software solutions including greenfencetm, RTAMO and Seasafe. In January 2024, Lloyd's Register signed

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

1824-511: 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 , a partner of
1881-413: The organisation changed its name to Lloyd's Register of Shipping. The Society printed the first Register of Ships in 1764 in order to give both underwriters and merchants an idea of the condition of the vessels they insured and chartered: ship hulls were graded by a lettered scale (A being the best), and ship's fittings (masts, rigging, and other equipment) were graded by number (1 being the best). Thus

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
1995-672: 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
2052-829: 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

The Register was published formerly by the joint venture company of Lloyd's Register-Fairplay, which was formed in July 2001 by the merger of Lloyd's Register's Maritime Information Publishing Group and Prime Publications Limited . Lloyd's Register sold its share of the venture to IHS Markit in 2009. The American Lloyd’s Registry of American and Foreign Shipping

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 . It was a scaled down design from ideas penned by Churchill. To carry 13 Churchill infantry tanks , 27 vehicles and nearly 200 men (in addition to

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
2280-490: The same landing craft to carry out the same operation in the civilian commercial market, providing there were reasonable port facilities. 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
2337-709: 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

2394-554: 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
2451-453: The speed of HMS Boxer at only 10 knots (19 km/h; 12 mph) but had a similar load while drawing only 3 ft (0.91 m) forward when beaching. 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
2508-554: 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)
2565-425: 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
2622-530: 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
2679-591: The war he observed trials on Brighton Sands of an LST in 1943 when its peacetime capabilities were obvious. 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
2736-470: 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
2793-423: The waterline and open vehicle decks with few internal bulkheads , has a reputation for being a high-risk design, to the point where the acronym is sometimes derisively expanded to "roll on/roll over". 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
2850-526: Was established in 1857, and the American Lloyd’s Register of American and Foreign Shipping issued from at least 1859 until at least 1883 by the "Board of American Lloyd's". Lloyd's Register's main office is located in London at 71 Fenchurch Street . Lloyd's Register also operates in more than 70 locations, serving clients based in 182 countries. Lloyd's Register has changed and expanded over
2907-470: 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

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
3021-529: Was named after a seventeenth-century coffee house in London that was frequented by merchants, marine underwriters, and others associated with shipping. The coffee house owner, Edward Lloyd , helped them to exchange information by circulating a printed sheet of all the news he heard. In 1760, the Register Society was formed by the customers of the coffee house who assembled the Register of Shipping ,

While modest in capacity, it could transport three semi trailers between Hyannis in Massachusetts and Nantucket Island, even in ice conditions. In 1957, the US military issued a contract to the Sun Shipbuilding and Dry Dock Company in Chester, Pennsylvania , for the construction of a new type of motorized vehicle carrier. The ship, USNS Comet , had

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
