Ship history

The vessel was built at the DSME shipyard in South Korea, where the construction started in August 2011. After final outfitting on the lay system in Rotterdam in spring 2013, the vessel started work for Heerema.

The Aegir joined the Heerema fleet back in 2013 as a deepwater construction vessel featuring J-lay and Reel-Lay capabilities via a large moonpool. Equipped also with a large heavy lift crane she was the first reel lay vessel to use a portable reel system, saving time that is typically taken by sailing back and forth to a shore base.

In October 2013, ‘Aegir’ was awarded KVNR’s (the Royal Association of Dutch Shipowners) Shipping Award. In 2014, she was a nominee for the 'Support Vessel of the Year' Award by Offshore Support Journal.


2018: After Heerema Marine Contractors’ strategically decided to reposition its core business to Heavy Lift, Decommissioning and Renewables, Ulstein Design & Solutions B.V. was contracted to provide design and engineering services to convert the Aegir into a fast sailing heavy lift vessel.

2020: The Aegir vessel is now transformed into a dedicated offshore heavy lift vessel. Aegir’s already massive 4,000-ton main crane and the fact that her hull design is based on Ulstein’s SOC 5000 heavy lift vessel design, is a key benefit in this development.

An update in November 2020 states that Aegir has successfully completed the installation of North Oil Company’s Al-Shaheen Gallaf 1 Project. Heerema was contracted for the transportation and installation of three topsides and three bridges by PTSC M&C Vietnam, who fabricated the structures at their yard in Vung Tau, Vietnam. The work involved the installation of three topsides weighing between 2000 and 2500 metric tons and three bridges weighing between 700-1100 metric tons. These were installed onto pre-installed jackets in the Al-Shaheen field located around 80 km north of Ras Laffan, Qatar. Aegir arrived at block 5 of the Al-Shaheen on October 19 and began the installing job. The Al-Shaheen oil field is Qatar’s largest and has a water depth of 60 meters with facilities consisting of 33 platforms and more than 300+ wells. The Al-Shaheen Gallaf 1 scope will support the North Oil Company’s ongoing development of the Al-Shaheen field. (Source: Nauticus Live)
