Marine Outdoor Power Supply Requirements

What is onshore power supply (Ops)?

The use of Onshore Power Supply (OPS) also commonly referred to as Alternate Marine Power or Cold Ironing, has already gained decades of experience, particularly with low-voltage supply. Other options for electrification in the ship-shore interface include battery charging, battery swapping, power banking and microgeneration.

What equipment does a power service vessel need?

Power service vessels can be equipped with single or multiple gas/steam turbines, reciprocating diesel, gas or dual fuel engines, or boilers for power generation. In this document, the requirements for the power generation, battery systems and distribution equipment installed on board are associated with an optional notation.

Can a power plant be used to provide power to vessel Marine Services?

Power plant systems may be used to provide power to vessel marine services and the arrangement is to be in accordance with Subsection 3/7. Lithium-ion battery systems are to comply with the full requirements of the Lithium-ion Batteries Requirements.

What are the requirements for a shore connection?

In addition, the following requirements are to be followed as applicable. The type of shore supply (AC or DC) is to be considered in the design of the shore connection. Thus, converters and/or associated transformers are to be provided for external power supply as applicable.

Does a shipboard generator need a high voltage shore connection?

Vessels equipped with a high voltage shore connection designed to power the vessel with the shore power alone, enabling the shipboard generators to be shut down while in port, are to comply with the requirements given in the ABS Guide for High Voltage Shore Connection.

Are lithium-ion batteries required to be installed in a power plant?

Where lithium-ion battery systems are installed as part of the power plant for power export, the installation is to comply with the applicable requirements in the ABS Requirements for Use of Lithium-ion Batteries in the Marine and Offshore Industries (Lithium-ion Batteries Requirements) as referenced in this Subsection.
