Astilleros Gondán will build the second ST 933 offshore tug for Østensjø Rederi, strengthening the company’s heavy-duty offshore towage capability
Østensjø Rederi has expanded its newbuild programme with an order for a second offshore tug, a sister vessel to NB C515, which is currently under construction at Astilleros Gondán.
The new offshore tug will be built to the proven Skipsteknisk ST 933 design and will be the largest and most powerful tug ever commissioned by Østensjø Rederi, significantly enhancing the company’s offshore towage capabilities.
With a bollard pull of 150 tonnes and a DP-2 dynamic positioning system, the tug will offer exceptional power, precision, and reliability. A comprehensive winch package enables the tug to perform complex tasks, supporting high operational flexibility.
Equipped with a diesel-electric hybrid propulsion system for fuel-efficient operations and prepared for Methanol fuel, the newbuild is an important step towards more sustainable operations and aligns with Østensjø Rederi’s target of reducing emissions.
The collaboration between Østensjø Rederi and Astilleros Gondan, and their shared commitment to producing high-quality offshore vessels, has spanned 20 years.
The newbuild contract further strengthens Østensjø Rederi’s dedication to maintaining a modern, reliable tug fleet, prepared for the future of offshore operations.
