A crane vessel, crane ship, crane barge, or floating crane is a ship with a crane specialized in lifting heavy loads, typically exceeding 1,500 t (1,476 long tons; 1,653 short tons) for modern ships. The largest crane vessels are used for offshore construction .
A heavy-lift ship is a vessel designed to move very large loads that cannot be transported by normal ships. They are of two types: Semi-submersible ships that take on water ballast to allow the load—usually another vessel—to be floated over the deck, whereupon the ballast is jettisoned and the ship's deck and cargo raised above the ...
The vessel is equipped with two revolving cranes built by Huisman Equipment B.V., each with a capacity of 10,000 t (11,000 short tons); the main cranes can be operated in tandem to jointly lift 20,000 t (22,000 short tons). After its completion in 2019, SSCV Sleipnir succeeded Heerema's earlier SSCV Thialf as the largest crane vessel in the world.
VB-10,000 performed its first lift on 9 October 2010, a 1,530-short-ton (1,390 t) topside and jacket which had toppled during a storm at Vermilion 285. Approximately a week later, VB-10,000 retrieved a 2,500-short-ton (2,300 t) topside which had been damaged by fire. [11] The Claw was used in 20 lift projects during its first year of deployment ...
The Hermod had two cranes at the stern. Originally the starboard-side crane was rated at 3,000 short tons (2,700 t) and the port-side at 2,000 short tons (1,800 t). [4] In 1984, the lifting capacities were upgraded to 5,000 and 4,000 short tons (4,500 and 3,600 t) respectively. [1] The main hoist could lift 92 m (302 ft) above the work deck.
Heavy lift ship transporting oil platform in Shetland. In transportation, heavy lift refers to the handling and installation of heavy items which are indivisible, and of weights generally accepted to be over 100 tons and of widths/heights of more than 100 meters. These oversized items are transported from one place to another (sometimes across ...
Using a cane on stairs can be particularly tricky, but the Mayo Clinic offers this advice: “As you go up steps, use your free hand to hold onto the railing if there is one. Step up first with ...
