Proman Stena Bulk christens methanol tanker Stena Prosperous in Singapore


Proman Stena Bulk, the joint venture between leading tanker company Stena Bulk and leading methanol producer Proman, has today christened Stena Prosperous during a ceremony at the Marina Bay Cruise Centre in Singapore.

After the ceremony, the 49,900 DWT IMOIIMeMAX vessel will be bunkered with a 20/80 green/conventional methanol blend, which delivers CO2e savings of 31% compared to the same voyage operated on Very Low Sulphur Fuel Oil (VLSFO), while making additional particulate matter (PM), sulphur oxides (SOx), and nitrogen oxides (NOx) savings. The blend delivers greenhouse gas emissions reductions below the 2025 target required by Fuel EU Maritime, further underlining methanol’s viability as a pathway fuel.

Stena Prosperous is the last of six vessels in Proman Stena Bulk’s joint venture fleet to be formally named, following the order for the six methanol-fuelled tankers being placed in 2019, and the first vessel being delivered in June 2022.

The naming ceremony was attended by representatives from Proman, Stena Bulk and guests and dignitaries from the wider shipping community. It concluded with the traditional christening and blessing, conducted by Mrs Krisztina Grütter, the vessel’s godmother.

Using methanol instead of conventional marine fuels virtually eliminates particulate matter and SOx, and cuts NOx by up to 80% during combustion. By increasing the amount of green methanol in the mix as its production ramps up, ship owners can deliver on the pathway for emissions reductions set by the IMO and the EU. The viability of this is demonstrated by the 20/80 blend used this week by Stena Prosperous.

Speaking at the naming ceremony, David Cassidy, Chief Executive of Proman, said: “Singapore is the world’s most important bunkering hub, so it’s fantastic to celebrate the naming of Stena Prosperous here, as we also celebrate the role methanol is playing in the decarbonisation of the industry. With its cleaner burning qualities, methanol delivers immediate air quality benefits today, and the pathway demonstrated by our 20/80 blending strategy here in Singapore means that ship owners are also increasingly seeing it as a viable marine fuel for the future.”

Erik Hånell, President and CEO of Stena Bulk, added: “Naming Stena Prosperous in Singapore has provided the perfect opportunity for us to mark the progress we have made in our joint venture with Proman over the last few years. We are proud of the track record of these tankers to date and are excited to be able to continue to prove to the market that by being pragmatic and flexible, we can make tangible steps towards decarbonisation.

“The vessel’s operations leverage the deep experience of methanol that Stena Bulk – and the wider Stena Sphere – have built over the last decade. This experience has moved the dial on how the industry views methanol as a marine fuel, helping to propel it from being an outside solution to a reality in-operation.”

Today, all six vessels are in commercial operation, running on methanol. Two of the vessels are long-term time-chartered to provide the market with opportunities to gain wider operational experience of methanol as a marine fuel.

The six-ship fleet is currently crewed and operated by Stena Sphere company Northern Marine Group, who have highlighted the technical similarities of the tankers to conventionally fuelled vessels, meaning that they do not require a completely new set of operating procedures.
