How might ocean going vessels meet regulations established by the International Maritime Organization (IMO) to reduce Greenhouse Gas (GHG) emissions and what role do ports and port authorities play to facilitate a transition to alternative fuels? The international shipping sector is considering multiple technology pathways towards de-carbonization and the Vancouver Fraser Port Authority has been proactively working to understand the needs of shippers and prepare for the anticipated energy transition. Ports traditionally have focused on providing infrastructure at shore-side and the transition to alternative fuels requires a broader view during future planning. The adoption of alternative fuels will not happen in isolation or by any one stakeholder in the global marine transportation supply chain with ports needing to act as a key facilitator. The Vancouver Fraser Port Authority, which manages the Port of Vancouver, has examined potential demand and usage patterns of alternative fuels with a current focus on Liquefied Natural Gas (LNG) as a Marine Fuel. The port authority has delved into a range of topics including ship-to-ship bunkering, economic viability, well-to-wake carbon and GHG performance, vessel design implications, vessel management and operational options. It is this last topic of operational options that is the focus of the presentation as it highlights how technologies might be leveraged in response to the IMO Carbon Intensity Indicator (Cii) and rating scheme. The paper presented by the Vancouver Fraser Port Authority shares knowledge and insight gained over the last several years as it has worked with industry and many stakeholders to facilitate the transition to alternative marine fuels.
