#IAPH2024 saw the launch of the first digital version of the Port Readiness Level for Marine Fuels (PRL-MF) self-assessment tool. This new digital iteration of the tool supports the assessment of the readiness levels of ports for bunkering operations involving the different low- and zero-carbon fuels. Established as a pilot project in 2022 – following joint work by the World Ports Climate Action Program (WPCAP), the IAPH Clean Marine Fuels working group, and Mission Innovation’s Zero Emission Shipping Mission – the PRL-MF is a fuel-agnostic framework that ports can use to self-assess their readiness and identify areas requiring further development to facilitate bunkering of a new low- or zero-carbon marine fuel. The tool was previously only available as a downloadable PDF. WPCAP worked with the US Department of Energy’s National Renewable Energy Laboratory and Pacific Northwest National Laboratory to develop an easy-to-use digital tool that includes a list of assessment criteria, with guiding information to support port efforts across research, development, and deployment phases. It facilitates self-assessment by bringing all relevant port personnel working together in a single system where information can be exchanged, saved and communicated as needed. This tool is for use by ports with the input of any relevant members of a port community, including the port authority, national maritime authority, ship-operating customers, and governments. To use the digital version of the tool, ports will first need to register and create an account at https://fuelreadyports.org/user/register. The registration is to be requested by the person appointed internally as the port administrator (responsible for overseeing all port readiness level assessments and related work) by the given port. Upon approval by IAPH, this port administrator, and ‘owner’ of the port’s account, will be able to assign additional colleagues as members of the port’s team. Please note that currently only IAPH member ports can join the digital system. Non-IAPH member ports and other interested parties are encouraged to use the publicly available pdf version of the tool or get in touch with IAPH technical director Antonis Michail to discuss joining options.
