Washington Maritime Blue has issued a request for proposals seeking a naval architecture firm to develop concept designs for a methanol bunker barge, according to Ship & Bunker. The initiative is tied to a planned methanol bunkering readiness exercise at Washington state’s Seattle-Tacoma Gateway.
The Proposed Vessel
As outlined in the RFP issued on May 11, the proposed barge would be unmanned and non-self-propelled, with an expected methanol carrying capacity of approximately 30,000 barrels. Ship & Bunker reports the vessel would be designed exclusively for the transport and transfer of methanol fuel, with intended use covering cargo, container, cruise, and ro-ro vessels.
What the Designs Must Cover
Contractors will be required to produce drawings addressing a broad range of technical and safety considerations, including:
- Bunkering procedures
- Methanol piping systems
- Tank arrangements
- Hazardous zone mapping
- Firefighting systems
- Emergency shutdown layouts
- Mooring arrangements
According to Ship & Bunker, these designs are intended to serve as a realistic technical foundation for discussions during the planned workshop.
September Workshop and Safety Focus
The concept designs will feed directly into a ship-to-ship methanol bunkering exercise forming part of a high-level risk assessment workshop scheduled for September 2026. Participants will examine operational requirements and safety considerations specific to methanol, including its toxicity, flammability, and low flash point.
Proposals are due by June 1, with the selected contractor expected to deliver the final designs by July 31, ahead of the September event.
Partners and Funding
Ship & Bunker reports the project is being carried out in collaboration with the Port of Seattle, Port of Tacoma, the Northwest Seaport Alliance, and ABS. The initiative is funded by the EPA and is part of a broader effort exploring green methanol as a marine fuel.
Does This Matter to You?
As methanol continues to gain traction as an alternative marine fuel, the development of safety frameworks and operational protocols for ship-to-ship methanol bunkering is increasingly relevant across the maritime sector. This initiative — focused on barge design standards, hazardous zone classifications, and emergency procedures — signals growing regulatory and industry attention toward the practical infrastructure required to support methanol bunkering at scale. The involvement of ABS and major port authorities in the Pacific Northwest adds institutional weight to the exercise, and the outcomes could inform future safety guidelines and bunkering readiness assessments at other ports considering methanol as part of their alternative fuel strategies.
