In 2000, it set a world record of 11,883 t by lifting Shell's Shearwater topsides, beaten by Saipem 7000 in 2004 with the Sabratha deck lifting of 12,150 t. [5] In 2004, it installed the topsides on BP's Holstein, at the time the world's largest spar. The lift was a record for the Gulf of Mexico: 7,810 t.
After straddling the payload, Pioneering Spirit takes on ballast to lower, and two sets of eight (one set per bow) retractable motion-compensated horizontal lifting beams are extended under the payload. Once the load is secure, the vessel offloads the ballast, rising in the water and partially transferring the load to the beams.
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.
Rigging of an asymmetrical scaffolding piece: the lifting beam is blue, the load is attached to the beam using grey slings. The lifting beam (also known as traverse, spreader beam) is a steel beam that is attached to the hook of the crane in order to spread the slings from one end of an elongated load (like a wall panel) to another.
The two main port and starboard cranes were installed by August 2018. [26] The vessel was christened SSCV Sleipnir by Mrs. Maha Hatfield on May 24, 2019, and embarked on sea trials and crane load tests afterwards. [27] Sea trials were completed in late June 2019. [11]
The 2nd Auxiliary hook can be deployed to a water depth of 450 m. The two cranes are capable of a tandem lift of 14,000 tonnes. Each crane was fitted with 15,600 hp (11,630 kW) engines to power the boom and load hoists, 9 tugger lines and the crane slewing system. The cranes use 48 miles (77 km) of wire rope of various diameters.
