AMP SYSTEMS / COLD IRONING
Alternative Maritime Power (AMP), also known as "cold ironing" or "shore power," is a technology that allows ships to turn off their auxiliary engines while docked and instead connect to a land-based power source. This technology provides several environmental and operational benefits. Here are some key points about AMP:
Major Port AMP Installation and Regulation Status
Regulation Implementation
NORTH AMERICA
• January 1, 2021 New Regulation took effect
• December 1, 2022 Published Interim Evaluation Report
• January 1, 2023 New requirements took effect for container/reefer/cruise vessels
• January 1, 2025 New requirements take effect for ro-ro and Southern California
tanker terminals
• January 1, 2027 New requirement take effect for Nothern California tanker
terminals
EU
EU Commission proposes new guidelines for mandatory use of onshore power supplying by ships docked in the existing EU Directive (Directive 2014/94/EU) in October 2021 - OPS will be established at TEN-T(Trans-European Transport Network) ports by end of 2025, Container Ships will be equipped with AMP facilities by January 2030
CHINA
The Air Pollution Prevention Act stipulates that new dock planning, design and construction should be equipped with an AMP system, already developed docks should be gradually converted into an AMP system, and ships entering the port should use AMP first.
It is mandatory that the vessel installed AMP is called at the port which has onshore power supply system.
ADDITIONAL EFFECTIVENESS
*CII (Carbon Intensity Indicator) Regulatory aspects : Expected to reduce CO2 emissions
Ex) 24,000 TEU simple calculation of CO2 emissions
AMP System General Arrangement
Shore Conn. Panel
The panel that receives shore power first on the ship, and it checks the connection status and electrical specifications of shore power, connects and disconnects shore power.
Socket Box
A device in which a cable for using shore power is leaded in from port to a ship.
AMP Cable Reel
A device for transferring cables from a ship to port for the use of shore power.
Transformer
A device that converts voltage for low voltage ships.
MSBD (AMP Incoming Panel)
A device that checks the connection status of shore power and the electrical specifications of shore power, synchronizes and changes between ship generators and shore power.
Container Type AMP
Cable Reel System and Shore Conn. Panel are installed in 40ft H/C container
AMP System Application
- Cable Reel Type:
˙Generally applied to Container vessel
˙The AMP cable management system (Cable Reel) is located onboard ship.
˙ Two parallel cables with three pilot conductors each shall be used for HVSC systems
up to a maximum power demand of 7.5 MVA.
˙Nominal voltage : 6.6Kv
2. Soket Box Type
˙Generally applied to Ro-Ro, Tanker, LNGC, Cruise
˙The AMP cable management system is located ashore.
˙The number and specifications of AMP cable sockets shall be applied differently for each type of ship.
˙ In case of LNGC, means shall be provided to facilitate emergency physical disconnection of the HVSC
cables in the event of ESD-2 (movement of the ship away from the dock) being detected.
˙Nominal voltage : 6.6kV or 11kV
- Fixed Container Type
˙Generally applied to Container vessel
˙ The AMP cable management system (Cable Reel) and the Shore Connection Panels are installed
in a 40ft H/C container which will be installed fixedly on the port or st’bd side of the ship.
˙ Two parallel cables with three pilot conductors each shall be used for HVSC systems up to a
maximum power demand of 7.5 MVA.
˙ Nominal voltage : 6.6kV
- Movable Container Type
˙Generally applied to Container vessel
˙ The AMP cable management system (Shore Cable Reel and Ship Cable Reel) and the Shore
Connection Panels are installed in a 40ft H/C container which will be located on the port or st'bd
side of the ship as a movable type.
˙ Two parallel cables with three pilot conductors each shall be used for HVSC systems up to a maximum power demand of 7.5 MVA.
˙Nominal voltage : 6.6kV
