Proven at sea: Nordstraum‘s real-life measurements validate the impact of smart bow design on fuel efficiency
The chemical tanker Nordstraum, owned by Utkilen in Bergen, has been successfully retrofitted with a newly designed bulbous bow, delivering significant improvements in fuel efficiency.
Although Nordstraum is 13 years old, detailed investigations carried out jointly by Utkilen and FKAB showed that substantial savings could be achieved by redesigning and installing a new forward hull form. The project has since been validated through extensive sailing, testing, and real-life performance measurements.
Among the many conversion options available to shipowners, this bulbous bow retrofit stands out as an extraordinary measure. It highlights Utkilen’s commitment to thoroughly exploring all possibilities to make its fleet more environmentally friendly.
Eirik Gjerde, Newbuilding & Innovation Manager at Utkilen, summarises the results: “We have just completed the final testing and can confirm a saving of 20 % – 2,6T/day reduction of fuel. The vessel received a C on the CII rating in 2024, we expect that to change to an A rating in 2026 and maintaining a B rating until 2030.”
These are impressive and highly encouraging figures. Utkilen is one of FKAB’s key clients and a clear forerunner in environmental thinking, continuously pursuing low-energy, high-performance vessels.
This approach aligns closely with FKAB’s own mindset, and the project represents a highly rewarding collaboration. They greatly value working together with partners who turn ambitious sustainability goals into measurable, real-world results.
