Østensjø Rederi has signed a contract with Spain’s Astilleros Gondán for the construction of a new offshore tug, marking the latest addition to the company’s towage fleet. The vessel, based on the Skipsteknisk ST 933 design, is slated for delivery in the first quarter of 2028 and will become the most powerful tug ever built for the company.
High-Bollard-Pull Tug to Enhance Offshore Towage Capability
The newbuild will feature a bollard pull of 150 tonnes and a DP-2 dynamic positioning system, enabling high precision for complex offshore operations. A large winch package has been incorporated to support a wide range of tasks and expand operational flexibility.
Kristian Helland Vea, CEO of Østensjø Rederi, said the vessel is designed to meet emerging requirements in offshore towage:
“The newbuild represents a major step in further strengthening our offshore towage fleet. Building on our extensive experience from tug operations, we have focused on developing a tug that delivers both the capacity and reliability required for offshore tug operations, meeting the demands of tomorrow. This tug checks all the boxes, and the combination of high bollard pull, advanced hybrid propulsion, and large winch capacity ensures exceptional operational flexibility and capacity.”
Hybrid Propulsion with Methanol-Ready Design
The tug will be equipped with a diesel-electric hybrid propulsion system aimed at improving fuel efficiency. The vessel will also be prepared for methanol fuel, supporting the company’s efforts to reduce emissions and align with future sustainability requirements.
Crew Comfort and Long-Term Yard Collaboration
In addition to its technical capabilities, the tug will include high-standard accommodation for 14 crew members, with measures implemented to minimise onboard noise and vibration.
The project extends Østensjø Rederi’s two-decade partnership with Astilleros Gondán, which has delivered multiple offshore vessels to the operator over the past 20 years.
