Norwegian Owners Gain Charter Extensions As Availability Tightens


Owners of offshore support vessels (OSVs) in Norway are again benefiting from rising demand and charter extensions as energy companies prepare for new field developments and maintenance.

Siem Offshore was the latest owner to report additional work for a multipurpose support vessel, gaining a contract extension for 2009-built Siem Dorado, keeping it employed in Brazil for most of 2024 in direct continuation of the current contract.


This MT 6017 MK II design vessel has a 100-tonne heave-compensated offshore crane, a 7 m by 7 m moonpool and remotely operated vehicle (ROV) for light construction duties and subsea operations. According to automatic identification system (AIS) data, this 4,869-gt, 94-m vessel was operating out of bases in Rio de Janeiro and Niteroi and at the Sepia field offshore Brazil.

In Norway, Equinor extended employment of Simon Møkster Shipping’s 2010-built PSV Stril Mermaid for another four months, until the end of June 2024.

Contract period

During that contract period, Floatel Superior will support maintenance of the Åsgard B floating production semi-submersible during Q2 and Q3 2025 and the Oseberg platforms from Q4 2025.

Floatel Superior is an accommodation and construction support vessel with Kongsberg dynamic positioning to DP3 class, capacity for 440 people in single-bed cabins, a telescopic gangway to transfer personnel to the host installation, two deck cranes, workshops, lay-down and storage areas and a helideck.
