Crane vessel

A crane vessel, crane ship or floating crane is a ship with a crane specialized in lifting heavy loads. The largest crane vessels are used for offshore construction. Conventional monohulls are used, but the largest crane vessels are often catamaran or semi-submersible types as they have increased stability. On a sheerleg crane, the crane is fixed and cannot rotate, and the vessel therefore is manoeuvered to place loads. As of 2019, the largest crane vessel in the world is the CNOOC Limited owned Lanjing, having 3 cranes of capacities 7500 tonnes, 4000 tonnes and 1600 tonnes.[1]

In medieval Europe, crane vessels which could be flexibly deployed in the whole port basin were introduced as early as the 14th century.[2]

During the age of sail, the sheer hulk was used extensively as a floating crane for tasks that required heavy lift. At the time, the heaviest single components of ships were the main masts, and sheer hulks were essential for removing and replacing them, but they were also used for other purposes. Some crane vessels had engines for propulsion, others needed to be towed with a tugboat.

In 1920, the 1898-built battleship USS Kearsarge was converted to a crane ship when a crane with a capacity of 250 tons was installed. Later it was renamed Crane Ship No. 1.[3] It was used, amongst other things, to place guns and other heavy items on other battleships under construction. Another remarkable feat was the raising of the submarine USS Squalus in 1939.

In 1942, the crane ships a.k.a. "Heavy Lift Ships" SS Empire Elgar (PQ16), SS Empire Bard (PQ15), and SS Empire Purcell (PQ16) were sent to the Russian Arctic ports of Archangel, Murmansk and Molotovsk (since renamed Sererodvinsk). Their role was to enable the unloading of the Arctic convoys where port installations were either destroyed by German bombers or were non existent (as at Bakaritsa quay Archangel).[4][5][6]

In 1949, J. Ray McDermott had Derrick Barge Four built, a barge that was outfitted with a revolving crane capable of lifting 150 tons. The arrival of this type of vessel changed the direction of the offshore construction industry. Instead of constructing oil platforms in parts, jackets and decks could be built onshore as modules. For use in the shallow part of the Gulf of Mexico, the cradle of the offshore industry, these barges sufficed.

In 1963, Heerema converted a Norwegian tanker, Sunnaas, into a crane vessel with a capacity of 300 tons, the first one in the offshore industry that was ship-shaped. It was renamed Global Adventurer. This type of crane vessel was better adapted to the harsh environment of the North Sea.

Semi-submersible giants

In 1978, Heerema had two semi-submersible crane vessels built, Hermod and Balder, each with one 2,000 ton and one 3,000 ton crane. Later both were upgraded to a higher capacity. This type of crane vessel was much less sensitive to sea swell, so that it was possible to operate on the North Sea during the winter months. The high stability also allowed for heavier lifts than was possible with a monohull. The larger capacity of the cranes reduced the installation time of a platform from a whole season to a few weeks. Inspired by this success similar vessels were built. In 1985 DB-102 was launched for McDermott, with two cranes with a capacity of 6,000 tons each. Micoperi ordered M7000 in 1986, designed with two cranes of 7,000 tons each.

However, due to an oil glut in the mid 1980s, the boom in the offshore industry was over, resulting in collaborations. In 1988, a joint venture between Heerema and McDermott was formed, HeereMac. In 1990 Micoperi had to apply for bankruptcy. Saipem – in the beginning of the 1970s a large heavy lift contractor, but only a small player in this field at the end of the 1980s – acquired M7000 from Micoperi in 1995, later renaming it Saipem 7000. In 1997 Heerema took over DB-102 from McDermott after discontinuation of their joint venture.[7] The ship was renamed Thialf and, after an upgrade in 2000 to twice 7,100 tons, it is now the largest crane vessel in the world.

Thialf can use both cranes to lift 14,200 t (14,000 long tons; 15,700 short tons) at a radius of 31.2 m (102 ft); in comparison, Saipem 7000 can use both cranes to lift a smaller load of 14,000 t (14,000 long tons; 15,000 short tons) at a wider radius of 41 m (135 ft).[8]

Lifting records

A heaviest single lift record was set in 2000 by Thialf for lifting the 11,883 t (11,695-long-ton; 13,099-short-ton) Shearwater topsides for Shell.[9][10] Saipem 7000 set a new record in October 2004 for the 12,150 t (11,960-long-ton; 13,390-short-ton) lift of Sabratha Deck.[11][12]

Under dynamic positioning, Saipem 7000 set another record in 2010 by lifting the 11,600 t (11,400-long-ton; 12,800-short-ton) BP Valhall Production topsides.[12]

In the event, the deck sailed out of Ulsan on Sept. 28, 2004, weighing 12,100 tonnes, including rigging, having been skidded onto the Dockwise transportation vessel Transshelf using hydraulic and strand jacks.

    On Oct. 30, the Transshelf arrived at the offshore site, following a four-week voyage via the Suez Canal. Two days later, the Saipem 7000 mated the deck to the jacket in a four-hour operation. Certifying authority Lloyd’s Register confirmed the weight as a world record for a single lift offshore. However, Saipem should top its own achievement later this year when the same vessel lifts the Piltun platform topsides into place offshore Sakhalin Island.

It originally had a lifting capacity of 120 metric tons, gradually raised to 200 tons by 2006, making it one of the largest in lifting capacity on Central European rivers. It is mainly used for building bridges, but is also commissioned to assist salvage operations, as well as to launch hydrofoils. It has rescued several ships; in 2019 it raised the sunken Hableány from the Danube at Budapest. The vessel is named after Scottish engineer Adam Clark (1811–1866).

Floating sheerleg

A floating sheerleg (also: shearleg) is a floating water vessel with a crane built on shear legs. Unlike other types of crane vessel, it is not capable of rotating its crane independently of its hull.

There is a huge variety in sheerleg capacity. The smaller cranes start around 50 ton in lifting capacity, with the largest being able to lift 10,000 tons. The bigger sheerlegs usually have their own propulsion system and have a large accommodation facility on board, while smaller units are floating pontoons that need to be towed to their workplace by tugboats.

Sheerlegs are commonly used for salvaging ships, assistance in shipbuilding, loading and unloading large cargo into ships, and bridge building. They have grown considerably larger over the last decades due to a marked increase in vessel, cargo, and component size (of ships, offshore oil rigs, and other large fabrications), resulting in heavier lifts both during construction and in salvage operations.

Guard ship

A guard ship is a warship assigned as a stationary guard in a port or harbour, as opposed to a coastal patrol boat which serves its protective role at sea.

Herman the German (crane vessel)

Titan, better known by its former nickname Herman the German (US Navy designation YD-171), is a large floating crane currently serving in the Panama Canal Zone performing heavy lifts for lock maintenance. Prior to its move to Panama in 1996, the crane was based at the Long Beach Naval Shipyard from the end of World War II until the yard's closure in 1995. It was seized from the German Kriegsmarine following the end of World War II as part of war reparations. The crane was built by Demag Cranes AG as Schwimmkran nr. 1 in 1941 for the Kriegsmarine, where it had served in the Baltic Sea tending German U-boats. MMSI number: 374940000

The crane was one of four sister ships, two of which are still afloat and in service.

SSCV Hermod was a semi-submersible crane vessel operated by Heerema Marine Contractors.

Kravtsovskoye oilfield

The Kravtsovskoye oilfield (Russian: Кравцовское нефтяное месторождение) is located within block D-6 in the coastal waters of the Baltic Sea, about 22 kilometres (14 mi) west of Russia's Kaliningrad Oblast. The deposit was opened in 1983 and extraction began in 2004. The extraction operation is conducted by Lukoil. Recoverable oil in the field is estimated at 9.1 million tonnes. The surrounding waters are about 30 metres (98 ft) deep.The field is developed with two platforms which were installed by using a Stanislav Yudin crane vessel. The firms involved in the field's infrastructure construction included Corall Central Design Bureau, Kaliningradmorneft, Krein-Shelf, Germanischer Lloyd, Gosgortekhnadzor, Siemens, and HRI Oilfield, L.P. Produced oil and associated gas is transported by a 47-kilometre (29 mi) underwater pipeline to the Romanovo oil-gathering unit. Crude oil is exported through the Izhevsky oil terminal.Due to its proximity to the Curonian Spit, a UNESCO World Heritage site lying within both Lithuania and the Oblast, concerns over the environmental impact of a spill at the site have been raised. During the 2000s the two states agreed to a joint environmental impact assessment of the D-6 project, including plans for oil spill mitigation. The assessment and mitigation project had not been completed as of 2010.

Mine countermeasures vessel

A mine countermeasures vessel or MCMV is a type of naval ship designed for the location of and destruction of naval mines which combines the role of a minesweeper and minehunter in one hull. The term MCMV is also applied collectively to minehunters and minesweepers.


A minehunter is a naval vessel that seeks, detects, and destroys individual naval mines. Minesweepers, on the other hand, clear mined areas as a whole, without prior detection of mines. A vessel that combines both of these roles is known as a mine countermeasures vessel (MCMV).

Offshore construction

Offshore construction is the installation of structures and facilities in a marine environment, usually for the production and transmission of electricity, oil, gas and other resources. It is also called maritime engineering.

Construction and pre-commissioning is typically performed as much as possible onshore. To optimize the costs and risks of installing large offshore platforms, different construction strategies have been developed.

One strategy is to fully construct the offshore facility onshore, and tow the installation to site floating on its own buoyancy. Bottom founded structure are lowered to the seabed by de-ballasting (see for instance Condeep or Cranefree), whilst floating structures are held in position with substantial mooring systems.

The size of offshore lifts can be reduced by making the construction modular, with each module being constructed onshore and then lifted using a crane vessel into place onto the platform. A number of very large crane vessels were built in the 1970s which allow very large single modules weighing up to 14,000 tonnes to be fabricated and then lifted into place.

Specialist floating hotel vessels known as flotels are used to accommodate workers during the construction and hook-up phases. This is a high cost activity due to the limited space and access to materials.

Oil platforms are key fixed installations from which drilling and production activity is carried out. Drilling rigs are either floating vessels for deeper water or jack-up designs which are a barge with liftable legs. Both of these types of vessel are constructed in marine yards but are often involved during the construction phase to pre-drill some production wells.

Other key factors in offshore construction are the weather window which defines periods of relatively light weather during which continuous construction or other offshore activity can take place. Safety is another key construction parameter, the main hazard obviously being a fall into the sea from which speedy recovery in cold waters is essential.

The main types of vessels used for pipe laying are the "Derrick Barge (DB)", the "Pipelay Barge (LB)" and the "Derrick/Lay barge (DLB)" combination. Diving bells in offshore construction are mainly used in water depths greater than 120 feet (40 m), less than that, the divers use a metal basket driven from an "A" frame from the deck. The basket is lowered to the water level, then the divers enter the water from it to a maximum of 120 feet (40 m). Bells can go to 1,500 feet (460 m), but are normally used at 400 to 800 feet (120 to 240 m).

Offshore construction includes foundations engineering, structural design, construction, and/or repair of offshore structures, both commercial and military, including:

Subsea oil and gas developments

Offshore platforms – fixed platforms, semi-submersibles, spars, tension leg platforms (TLPs), floating production storage and offloading (FPSOs), etc.

Floating oil and gas platforms – semi-submersibles, spars, TLPs, FPSOs, etc.

Offshore wind power

Submarine pipelines

Repair ship

A repair ship is a naval auxiliary ship designed to provide maintenance support to warships. Repair ships provide similar services to destroyer, submarine and seaplane tenders or depot ships, but may offer a broader range of repair capability including equipment and personnel for repair of more significant machinery failures or battle damage.

USS Guardian (MCM-5)

USS Guardian (MCM-5) was an Avenger-class mine countermeasures ship of the United States Navy, and was the second Navy ship to bear that name. The hulls of the Avenger-class ships are constructed of wood with an external coat of fiberglass.

Guardian was laid down on 8 May 1985 by Peterson Builders, Sturgeon Bay, Wisconsin; launched on 20 June 1987; and commissioned on 16 December 1989. In 2010, she became the first mine countermeasures vessel in the Seventh Fleet modified for a mixed-sex crew, with separate head facilities.

On 17 January 2013, Guardian ran aground on Tubbataha Reef, in a protected area of the Philippines in the middle of the Sulu Sea. The vessel was turned and pushed further onto the reef by wave action. Unable to be recovered, the vessel was decommissioned and struck from the U.S. Naval Vessel Register on 15 February 2013. After removal of fuel and useful equipment, and after the upper superstructure was cut and lifted off of the minehunter, the wooden hull was sequentially chainsawed into four sections and lifted off of the reef by the dynamic positioning crane vessel MV Jascon 25. The bow section was cut and removed by crane on 26 March 2013. It was originally planned to cut the hull into three pieces, but the stern section had to be cut in half again. The last stern section was removed by crane from Tubbataha Reef on 30 March 2013.
