Kongsberg Maritime has won a contract to supply design, engineering, and equipment for two biofuel and methanol-ready chemical tankers for Swedish tanker operator Sirius Rederi.

The low emission 15,000 dwt tankers will feature a range of Kongsberg Maritime equipment and can operate on battery-powered hybrid propulsion. Options for further vessels are included in the contract.

This latest contract builds on a current nine-ship programme with fellow Swedish owner Terntank, with a similar design and equipment package. All 11 vessels will be built at the China Merchants Jinling Shipyard (Yangzhou) Dingheng. The first ship for Sirius will be delivered in July 2026

Rune Ekornesvåg, Sales Director Ship Design in Kongsberg Maritime, said: “This latest contract for our fuel efficient and low emission tanker design, confirms the continuing drive by progressive ship owners to adopt sustainable technologies into fleet renewals. We’re delighted to be working with Sirius and China Merchants Jinling Shipyard on this project, to deliver the next generation of cargo ship, with a combination of energy saving and clean technologies.”

Since the yard signed the first 15,000-ton LNG dual-fuel chemical tanker contract with Kongsberg Maritime’s design team in 2014, we have opened the door to the chemical tanker market in Northern Europe, with cutting-edge energy-saving and low-carbon designs. This was already an advanced design eight years ago, it was a challenge for China Merchants Jinling Shipyard and Kongsberg Maritime, but we succeeded with our joint efforts,” commented China Merchants Jinling Shipyard.

The new vessels are to have an Energy Efficiency Design Index (EEDI) close to 40% below the 2025 Phase 3 requirements.
