Norway’s Kongsberg Maritime will provide design, engineering and equipment for a pair of 15,000dwt MGO/biofuel and methanol-ready chemical tankers for Swedish tanker operator Sirius Rederi AB. 

The first ship is expected to be delivered in July 2026, whilst options for further chemical tanker ships are included.

This latest contract builds on a current nine-ship programme with fellow Swedish owner Terntank, with a similar design and equipment package.

As it is reported, all eleven vessels will be built at the China Merchants Jinling Shipyard (Yangzhou) Dingheng.

As part of a contract valued at around €8.3 million, Kongsberg Maritime will also supply – in addition to design and engineering services – steering gear, Promas with flap rudder and CPP, tunnel thruster with Mcon thruster control system, K-Chief integrated automation systems including Vessel Insight, AutoChief propulsion control system and deck machinery.

The new units, which can operate on battery-powered hybrid propulsion, are to have an energy efficiency design index close to 40% below the 2025 phase 3 requirements, as the company explains.

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.”

Jonas Backman, managing director of Sirius Rederi AB, pointed out that with these vessels the company is well on its “Pathway to ZERO.”

“Our new tanker has been designed to provide the highest levels of sustainability, efficiency and safety as well as excellent working conditions,” he added.
