Heerema’s CEO, Koos-Jan van Brouwershaven noted that ‘we set records to break them, and we are proud to have worked alongside our client Vår Energi to complete the Jotun-B removal with mighty Sleipnir safely, sustainably, and in the shortest possible time.’ Now that the Jotun-B jacket has been safely and sustainably transported to Vats, it will end its lifecycle by being recycled up to 99%. By using LNG, Sleipnir reduces CO2 emissions by 25%, reduces NOx emissions by 92%, reduces SOx emissions by 99%, and Particulate Materials by <99% compared to traditional Marine Gas Oil crane vessels. Sleipnir is the world’s most sustainable SSCV, and during the project, the vessel performed the full removal operations while running on emission-reducing LNG fuel. Additionally, Heerema fabricated a 40m long spreaderbar within 2mm tolerance for a tight, but perfect fit. The entire removal scope in the Jotun Field was completed in only four days.ĭuring this project, skirt piles with diameters 2.7m and 80mm wall thickness were cut subsea, the largest ever done in this way. More information regarding the specifications of the Sleipnir can be found at: decommissioning work was completed safely, sustainably, and one day ahead of schedule the result of excellent collaboration between Heerema and Vår Energi. The jacket was built by Heerema fabrication Yard in Vlissingen, the Netherlands, weighing 9,200 tonnes, 135 meters tall with a footprint of 65X65 metres.Īfter the successful installation of the jacket, Sleipnir safely executed the installation of the topsides, including he main support frame and the living quarters. Heerema’s SSCV Sleipnir installed the jacket for the new Peregrino C platform. The Peregrino field -in the Campos Basin- is Equinor’s most important project in Brazil and their largest international endeavour as an operator. Sleipnir was contracted to install a total of 38,000-ton of operational units. Lifting a module of 15,300 tonnes was never done by a crane vessel before. The largest energy project in the history of the State of Israel.ĭuring this project Heerema’s SSCV Sleipnir set a new world record, completing a 15,300 tonnes lift, installing the topsides for Noble Energy’s Leviathan development in the Mediterranean. In the last 7 months, Sleipnir has been involved in various projects, including: Coupled with an IMO- and US Coast Guard-approved ballast water management system, Sleipnir operates sustainably across all environmental jurisdictions.Ĭheck out the below video below for a helicopter and inside view of this amazing vessel: The vessel further stands out as the world’s first crane vessel with dual-fuel engines running on Marine Gas Oil (MGO) and Liquefied Natural Gas (LNG). With its single-lift capability catering to larger integrated structures than previously possible, Sleipnir will minimise offshore assembly work and raise operational efficiency to a new level, while not compromising the flexibility and robustness of traditional installation methodologies. Sleipnir can accommodate 400 persons and is deployed globally for installing and removing jackets, topsides, deep-water foundations, moorings and other offshore structures.
