SSCV Thialf is a huge semi-submersible crane vessel operated by the Netherlands-based Heerema Marine Contractors; it was the largest crane vessel in the world until the {{ship|SSCV|Sleipnir}} became the largest in 2019.
History
The ship was constructed in 1985 as DB-102 for McDermott International by Mitsui Engineering & Shipbuilding Co., Ltd. In 1997, it was taken over by Heerema Marine Contractors after discontinuation of their joint venture with McDermott, HeereMac, and renamed Thialf.
Layout
The Thialf has two cranes with a combined maximum lifting capacity of {{convert|14200|MT}}.{{cite web|url=http://absapps.eagle.org/safenet/record/record_vesseldetailsprinparticular?Classno=8503569&Accesstype=PUBLIC&ReferrerApplication=PUBLIC |title=American Bureau of Shipping Record, Thialf |url-status=dead |archiveurl=https://web.archive.org/web/20090420100116/http://absapps.eagle.org/safenet/record/record_vesseldetailsprinparticular?Classno=8503569&Accesstype=PUBLIC&ReferrerApplication=PUBLIC |archivedate=April 20, 2009 }}
It is equipped with a class III dynamic positioning system. Propulsion and position keeping is by six 5,500-kW retractable azimuthing thrusters. For shallow waters, there are 12 Flipper Delta anchors at 22.5 t, with {{convert|2500|m|sp=us}}, 80 mm mooring wire.
The hull consists of two pontoons with four columns each. Transit draft is about {{convert|12|m|sp=us}}. For lifting operations, it is normally ballasted down to {{convert|26.6|m|ftin|abbr=on}}. This way the pontoons (with a draft of {{cvt|13.6|m|ftin|disp=comma}}) are well submerged to reduce the effect of waves and swell.
It is able to accommodate 736 people.
Its lightship weight is 72,484 t.
Noteworthy projects
- Installing the pylon of the Erasmus Bridge in 1995.
- Decommissioning of the Brent Spar in 1998.
- 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.{{cite web|url=http://www.lr.org/News+and+Events/News+Archive/2004/Lloyds+Register+EMEA+assists+world+record+lift+for+Sabratha+topsides+installation.htm |publisher=Lloyd register |title=Lloyd's Register EMEA assists world record lift for Sabratha topsides installation |url-status=dead |archiveurl=https://web.archive.org/web/20070303003157/http://www.lr.org/News+and+Events/News+Archive/2004/Lloyds+Register+EMEA+assists+world+record+lift+for+Sabratha+topsides+installation.htm |archivedate=March 3, 2007 }}
- 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. The current{{As of when|date=May 2024}} record for Gulf of Mexico is now held by the Saipem 7000 with the 9,521 t of PEMEX PB-KU-A2 deck installed in March 2007.{{cite web | url = http://www.rigzone.com/news/article.asp?a_id=43601| title = Saipem Sets New Record in Mexico}}
- In 2005, it installed the heaviest single piece foundation piles: 2.74 meters diameter × 190 meters long, weighing 818 t each for Chevron's Benguela Belize compliant tower.
- In 2009, the ship became involved in the Alpha Ventus project, the first German offshore windfarm.
- 2017-2018: Thialf was involved in the installation of the platform sections of the Johan Sverdrup Complex, part of the development of the Johan Sverdrup oil field.{{cite web | url = https://issuu.com/pms72/docs/iro_catalogue_2019/s/78851| title = Special projects thanks to Dutch offshore contractors}}
