Naming ceremony for methanol-fuelled Stena Promise in the Port of Rotterdam

Stena Promise is the third of four methanol-fuelled vessels to be delivered to the joint venture and was delivered in November 2022. All four vessels in the IMOIIMeMax series have demonstrated an unprecedentedly low EEDI (Energy Efficiency Design Index) value while running on methanol.

Proman Stena Bulk’s IMOIIMeMax vessel series has achieved an EEDI 11% below the 2025 Phase 3 requirements – setting a new benchmark for methanol-fuelled tankers and further proving the operational viability of methanol as a marine fuel. The benchmark reflects industry-leading design improvements and technologies to maximise energy efficiency.

During its commercial operations, Stena Promise has already been operating full time on conventional methanol from natural gas. The vessel will use approximately 11,500 tonnes of methanol as fuel per year, significantly reducing GHG emissions compared to conventional marine fuels.

Naming ceremony 

The naming ceremony saw dignitaries and guests from both Proman and Stena Bulk, and from across the maritime industry, gather to celebrate the methanol-fuelled joint venture fleet. This was the first Naming Ceremony for a methanol-fuelled vessel held in the Port of Rotterdam.

The naming ceremony was held in Rotterdam in recognition of the port’s unique contribution to the maritime decarbonisation agenda. The Port is the largest methanol hub in north-western Europe, and ship-to-ship bunkering has taken place at the port successfully several times, including for the first JV vessel Stena Pro Patria in August 2022.

DNV has reported that over 106 methanol-fuelled ships are on order as of the end of March according to DNV. This includes container lines, dry bulk and tanker orders, as well as cruise sector operators.
