Shore Power technology, as an important measure for the green development of the shipping industry, has made significant progress in recent years, but it still faces a series of technical problems.
1. Ship-to-shore technology matching issues
Shore Power matching is one of the most complex and critical issues in shore power supply. Because ships come from all over the world, there are technical differences in their power systems, including inconsistencies in power supply systems, shore power interfaces, and power supply methods. This results in the need to solve many technical problems during the construction and use of shore power facilities to ensure effective connection and stable power supply between ships and shores.
Differences in power supply systems: Power systems in different countries and regions may adopt different voltage and frequency standards, and the ship's power system also needs to adapt. Therefore, during the shore power supply process, it is necessary to ensure that the shore power facilities match the power system of the ship's power system to avoid power supply problems caused by power system inconsistencies.
Different shore power interface standards: Ships have different shore power interface standards, and ships of different ship types and ages may use different interface methods. This requires ports to consider the compatibility of multiple interface standards when building shore power facilities, making construction and maintenance more difficult.
Inconsistent power supply methods: Ships may require different power supply methods during docking, such as low-voltage power supply, high-voltage power supply, or hybrid power supply, etc. This requires shore power facilities to have the ability to switch between multiple power supply modes to meet the power needs of different ships.
2. Matching issues of ship-to-shore communication protocols
Effective communication between ship and shore is an important guarantee for ensuring the stability and security of shore power supply. However, due to possible differences in communication protocols between ships and ports, poor communication or information transmission errors may occur during shore power supply. This requires both ship and shore to adopt a unified communication protocol or establish a compatible communication mechanism to ensure accurate transmission of information and timely response.
3. Matching of ship-to-shore protection functions
There may be differences in electrical protection between ships and shore power facilities, such as overload protection, short circuit protection, grounding protection, etc. In order to ensure electrical safety during shore power supply, both the ship and the shore need to match and coordinate the protection functions. This requires that the ship's electrical protection needs be fully considered when designing shore power facilities, and corresponding protection measures must be formulated to ensure the stable operation of the power supply system.
4. Ship-to-shore PMS system matching issues
The matching between the ship's power management system and shore power facilities is also one of the challenges faced by Shore Power technology. The PMS system is responsible for the monitoring, control and management of the ship's power system, while the shore power facilities require effective data exchange and collaborative work with the PMS system. However, due to differences in PMS systems of different ships, data incompatibility or control signal conflicts may occur during shore power supply. This requires in-depth cooperation and coordination between ship and shore on the PMS system to ensure the stability and safety of the power supply system.
5. Cable management system compliance issues
Cable management is an important link that cannot be ignored in the shore power supply process. The laying, connection and maintenance of cables need to follow certain specifications and standards to ensure the safety and reliability of the power supply system. However, in actual operation, non-compliance with specifications may occur during cable laying and connection due to possible differences in cable management systems between ships and ports. This requires in-depth communication and coordination between ship and shore on cable management to ensure the compliance and safety of the cable management system.
