- DNV introduces updated rules for safe tanker shore power, addressing safety concerns in hazardous cargo transport and industry regulations.
- Collaborative efforts by industry groups, including OCIMF, IACS, and DNV, fill gaps in standards, develop guidelines for terminals, and ensure a safe, standardized approach.
- The growing importance of shore power due to emissions reduction regulations prompts early consideration in ship planning, emphasizing efficiency, compliance, and potential retrofitting challenges.
Shore Power
DNV’s Shore Power class notation aids tanker owners in adopting emissions-reducing shore power while berthed. Collaboratively developed rules align with global legislation aiming to cut ship emissions during port stays.
Specifically designed for tanker safety, effective from July 2023, this notation addresses the rising demand for emission control strategies, prompted by CARB’s and EU’s regulations, emphasizing the importance of onshore power supply for vessels.
Cargo Safety
DNV prioritizes tanker safety amid shore power adoption due to flammable cargo risks. Tankers’ unique cargoes demand specialized rules for safe onshore connections, focusing on preventing sparks and handling flammable vapours.
Compliance relies on global IEC standards, mandating installation and testing of shore power by authorized bodies, ensuring a safe onboard environment.
Attention to system safety onboard and at ports is critical, requiring protective features to prevent accidents and ensure safety during connection points and cable arrangements for tankers.
Design Adaptations
- DNV’s Shore Power rules accommodate diverse ship designs while prioritizing safety. Addressing regulatory gaps, they aim for standardized, safe connection points, focusing on compatibility and technology advancements.
- Collaborative efforts with industry players aim to establish safety guidelines, crucial for personnel and asset well-being during tanker operations amid regulatory changes.
- Safety considerations dictate midship shore power connections, balancing safety with terminal design challenges, particularly in hazardous areas. The goal is to ensure safety without hindering innovative shipbuilding approaches.
Industry Collaboration
DNV’s Shore Power rules updated with collaborative industry input ensure safe electrical connections and cable protection, preventing hazards during tanker shore power usage.
The Onshore Power Supply Work Group, including OCIMF and standards institutes, contributes to comprehensive guidelines for tanker and terminal shore power applications.
Decarbonization Emphasis
Port of Gothenburg’s “Green Cable” shoreside power system sets an innovative standard, aiming for international adoption at its Energy Terminal.
Shore power is increasingly crucial for tanker efficiency and emission reduction, aligning with evolving decarbonization regulations.
Consideration of newbuilding stages and potential retrofitting urges shipowners to plan, while DNV contemplates offering ‘shore-power-ready’ qualifiers. Evolving maritime standards emphasize shore power as a realistic in-port emission solution, urging industry vigilance in following trends.
