The adoption of an Onshore Power Supply (OPS) brings environmental advantages to maritime operations in ports and terminals. By using shore-based electrical power while at a berth, ships can stop running their onboard diesel generators, reducing their emissions, contributing to improved local air quality and potentially reducing Greenhouse Gas (GHG) emissions. This information paper serves as guidance for the design, implementation and operation of OPS systems for tankers and marine terminals.
This paper provides recommendations for the design, implementation, and operation of OPS systems for terminals and all tanker types, except gas carriers. It offers guidance on the safe and efficient delivery and use of shore-based electrical power to ships at a berth, promoting environmental protection and regulatory compliance. It supersedes OCIMF’s information paper Onshore Power Supply Systems: Preliminary Design Recommendations for Tankers and Terminals (2023).
