{{Short description|Ship with a crane specialized for lifting heavy loads}}
[[File:Lodbrok i Ystads hamn 5 nov 2020.jpg|thumb|''Lodbrok'' is a floating crane, in the [[harbor]] of [[Ystad]] 2020.]]
A '''crane vessel''', '''crane ship''', '''crane barge''', or '''floating crane''' is a [[ship]] with a [[Crane (machine)|crane]] specialized in lifting heavy loads, typically exceeding {{cvt|1500|MT|0}} for modern ships. The largest crane vessels are used for [[offshore construction]].<ref name="Gerwick 2007" />

The cranes are fitted to conventional [[monohull]]s and [[barge]]s, but the largest crane vessels are often [[catamaran]] or [[semi-submersible]] types which provide enhanced stability and reduced platform motion. Many crane vessels are fitted with one or more rotating cranes. Some of the largest crane vessels use fixed [[sheerleg]]s instead; in these designs, the crane cannot rotate relative to the ship, and the vessel must be manoeuvered to place loads. Other vessels use large [[gantry crane]]s and straddle the load.<ref name="Gerwick 2007" />

==Types==
There are several major configurations  of crane vessel, usually with overlapping ranges of functionality, but each has at least one major advantage over the others in some circumstances, and consequently all these arrangements coexist.<ref name="Gerwick 2007" />

===Sheer-legs barges===
[[File:TAKLIFT 4 IMO 8010506 Floating Sheerleg, Port of Rotterdam pic3.jpg|thumb|Taklift 4 Sheer-leg barge]]
{{Main|Floating sheerleg}}
A [[Sheer-legs barge]] is a barge with [[sheer-legs]] mounted at one end, which can lift loads and [[Luff (crane)|luff]] the sheer-legs to adjust the reach, but cannot swing the load independently of the hull orientation. A typical arrangement has a substantial [[A-frame]] hinged at the stern, supported by stays to the bow. When the load has been lifted, the barge is maneuvered to the position where the load is to be lowered by onboard thrusters or tugs, and the load is lowered. A sheer-legs barge always keeps the load in the line of maximum static stability, and may use ballasting at the bow to increase longitudinal righting moment to compensate for the load. The sheer-legs arrangement is more economical to manufacture and maintain than a slewing crane, but may be less convenient as the whole vessel must be moved to precise position for lifting and lowering. It is usual to luff the sheer-legs before lifting to a position suitable for both lifting and setting the load, as luffing under load is generally slow, and there is seldom any need.<ref name="Gerwick 2007" />

===Hammerhead crane barges===
[[File:HLV Svanen at Belwind.jpg|thumb|Catamaran HLV ''Svanen'' with hammerhead crane]]
A heavy lift [[hammerhead crane]] barge has a fixed hammerhead crane, which neither slews nor luffs, but has a constant reach. They are operated in a similar way to sheer-legs barges. This arrangement may be mounted on a catamaran barge which allows it to straddle a bridge pier to lower a prefabricated section into place.<ref name="Gerwick 2007" />

===Catamaran gantry cranes===
[[File:SP-57 A to WD-89 (11442548985).jpg|thumb|Catamaran gantry crane vessel ''[[VB-10,000 (ship)|VB-10,000]]'']]
[[Catamaran]] heavy lift barges that consist of two barges connected by [[gantry crane]]s across the top have been used in sheltered water like harbours and rivers. To reduce listing moments on the barges, the gantries may be attached to the hulls by pinned joints at the ends, allowing some independent roll. The gantry trusses are usually fitted at both ends of the barges, allowing lifts of long loads.<ref name="Gerwick 2007" />

===Semi-submersibles===
[[File:Balder off Trinidad.JPG|thumb|Semi-submersible ''Balder'']]
{{Main|Semi-submersible platform}}
Semi-submersible crane platforms have advantages where the water is too deep or the bottom composition unsuitable for a jack-up, and the water conditions are frequently too rough for efficient use of conventional hulls. The semi-submersible hull form has a lesser and slower response to waves and swell, due to reduced [[waterplane area]], and [[Ship stability|stability]] and [[righting moment]] are adjustable by [[Ballast|ballasting]] to suit the load. The gaps between the columns also allow waves to pass between then with little impact on the vessel. Disadvantages are lower inherent stability, and much greater cost and complexity.<ref name="Gerwick 2007" />

The low waterplane area causes a low heave response, and this can be utilised to function as a tension leg platform by using vertical mooring lines to anchor piles or clump weights on the seabed sufficient to prevent heave in the prevailing sea state. In this configuration heave sensitive operations can be  done with precision and control.<ref name="Gerwick 2007" />

===Revolving derrick barge===
[[File:Space Shuttle Enterprise lifted onto deck of the U.S.S. Intrepid (7402541782).jpg|thumb|right|Revolving derrick barge ''[[Weeks 533]]'' lifting [[Space Shuttle Enterprise|''Enterprise'']]]]
A revolving derrick barge is a slewing crane mounted on a barge, which can be rotated independently of the hull when carrying a load. These are highly versatile, but also expensive, complex, and have some limitations, particularly in the sea states in which they can safely operate. They are usually operated from a fixed position, and use the slewing and luffing capabilities of the derrick to position the crane tip for picking and setting the load<ref name="Gerwick 2007" />

The arrangement is a compromise of structural and stability requirements balanced against reach versatility, load capacity, and cost. One of the advantages of the slewing derrick is the ability to reach loads carried on the deck of the vessel itself. Compared to land-based cranes, the additional dynamic loads and motion in a seaway complicate the operation and safety. Position and movement of the boom tip are affected by all six degrees of freedom, magnified by distance from the centres of motion of the vessel, and varying during a lifting operation as the position of the tip is moved relative to the vessel.<ref name="Gerwick 2007" />

===Jack-up construction barge===
{{Main|Jack-up rig}}
A Jack-up construction barge is a barge fitted with four to eight legs, each with a jacking system that can grip the leg and move it up or down relative to the hull, lock it in place and move back along the leg to grip it again for a further jacking operation. The hull is lifted clear of the wave tops in the working position, and the mass of the barge and any additional load is supported by the bases of the legs, which should preferably spread the load as evenly as possible. During the jack-up operation the barge is secured in place by a taut mooring spread of anchors. Once at working height the legs can be released one at a time and driven deeper with pile driving hammers for greater stability. Removal is basically a similar procedure in reverse, with the legs being pulled out of the bottom ground one at a time after the hull is afloat, while the anchor spread limits side forces imposed by waves. Water jetting, sustained tension, and/or low pressure water injection at the base of the leg may be used to release firmly embedded legs. These rigs are free from motion response to sea conditions, but need occasional calm conditions to move. Performance is strongly dependent on seabed characteristics.<ref name="Gerwick 2007" />

==Capacity==
The three main measures of capacity are load, reach, and lift height. Other factors of importance are hull draught, depth to which the hook can be lowered (for offshore work), and sea state limits for transit and lifting.<ref name="Gerwick 2007" />

==Operation and safety==

The interaction of the [[six degrees of freedom]] of the vessel, the response to the [[sea state]] and wind, and the position and motion of the upper block due to crane geometry and operational motion, can make the upper block describe a complex three-dimensional path in space. The load path is even more complex, and there may be various [[resonances]] of vessel, crane and load which must be managed, generally by passing through those conditions as soon as reasonably practicable, but [[motion compensation]] systems may help at times. Accelerations, [[Jerk (physics)|jerk]] loads and impacts between the load and surroundings must be minimised and limited to levels which do not cause unacceptable damage. Some of these responses are inherent to the combination of vessel, crane and load, and others depend on sea state and wind forces. Pick up and set down are the critical stages for impact loads. During pickup there may be relative movement between the support on which the load stands and the hook, and if the load cannot be lifted clear before the gap closes, there will be impact. Similarly when setting the load down, it should be done as smoothly as possible, and once in contact should be allowed to settle as soon as possible to avoid re-lifting and pounding on the base structure.<ref name="Gerwick 2007" />

==History==
{{More citations needed section|date=February 2021}}
In [[Middle Ages|medieval]] Europe, crane vessels which could be flexibly deployed in the whole port basin were introduced as early as the 14th century.<ref>Michael Matheus: "Mittelalterliche Hafenkräne," in: [[Uta Lindgren]] (ed.): Europäische Technik im Mittelalter. 800-1400, Berlin 2001 (4th ed.), p. 346 {{ISBN|3-7861-1748-9}}</ref>

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 [[Marine propulsion|engine]]s for propulsion, others needed to be towed with a [[tugboat]].

[[Image:USS Kearsarge as crane ship AB-1.jpg|thumb|left|{{USS|Kearsarge|BB-5|6}} as ''Crane Ship No. 1'']]
In 1920, the 1898-built [[battleship]] {{USS|Kearsarge|BB-5|6}} was converted to a crane ship when a [[crane (machine)|crane]] with a capacity of 250 tons was installed. Later it was renamed ''Crane Ship No. 1''.<ref>{{cite web|url=https://books.google.com/books?id=DygDAAAAMBAJ&q=Popular+Mechanics+1931+curtiss&pg=PA35|title=Popular Science|work=google.com|date=November 1931}}</ref> 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|SS-192|6}} in 1939.

In 1942, the crane ships a.k.a. "Heavy Lift Ships" [[SS Empire Elgar|SS ''Empire Elgar'']] ([[Convoy PQ 16|PQ 16]]), [[SS Empire Bard|SS ''Empire Bard'']] ([[Convoy PQ 15|PQ 15]]), and SS ''Empire Purcell'' (PQ 16) were sent to the Russian Arctic ports of [[Archangelsk]], [[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 [[bomber]]s or were non existent (as at Bakaritsa quay Archangel).<ref>{{Cite web |url=http://www.nvr.navy.mil/NVRSERVICECRAFT/C_YD.HTM |title=US Navy list of FLOATING CRANE (N-S-P),YD |access-date=2017-03-29 |archive-url=https://web.archive.org/web/20170330083658/http://www.nvr.navy.mil/NVRSERVICECRAFT/C_YD.HTM |archive-date=2017-03-30 |url-status=dead }}</ref><ref>[http://www.navsource.org/archives/14/26idx.htm navsource.org, TD- Cranes]</ref><ref>[https://www.navalhistory.org/2016/05/19/herman-the-german navalhistory.org, By Jon Hoppe]</ref>

In 1949, [[J. Ray McDermott]] had [[Derrick|''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 platform]]s 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 [[Norway|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]].

[[File:SSCVThialf.jpg|thumb|{{ship|SSCV|Thialf}} in a Norwegian fjord]]

===Semi-submersible giants===
In 1978, Heerema had two semi-submersible crane vessels built, {{ship||Hermod|ship|2}} and {{ship|DCV|Balder||2}}, each with one 2,000 [[short ton|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 [[Instantaneous stability|stability]] also allowed for heavier lifts than was possible with a monohull. The larger capacity of the cranes reduced the installation time of a [[Oil platform|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 [[1980s oil glut|oil glut in the mid 1980s]], the [[economic boom|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 {{ship||Saipem 7000||2}}. In 1997 Heerema took over ''DB-102'' from McDermott after discontinuation of their joint venture.<ref>{{cite web|url=http://www.gasandoil.com/goc/features/fex80557.htm|title=J. Ray McDermott ends HeereMac joint venture|work=gasandoil.com}}</ref> The ship was renamed {{ship|SSCV|Thialf||2}} and subsequently was upgraded in 2000 to a lifting capacity of twice 7,100 tons.

''Thialf'' can use both cranes in tandem to lift {{convert|14200|t|abbr=on}} at a radius of {{convert|31.2|m|abbr=on}}; in comparison, ''Saipem 7000'' can use both cranes to lift a smaller load of {{convert|14000|t|abbr=on}} at a wider radius of {{convert|41|m|abbr=on}}.<ref name=MI-Mambra>{{cite web |url=https://www.marineinsight.com/types-of-ships/the-saipem-7000-one-of-the-biggest-cranes-in-the-world/ |title=The Saipem 7000: One of the Biggest Cranes in the World |author=Mambra, Shamseer |date=27 December 2017 |publisher=Marine Insight |access-date=21 March 2018}}</ref>
