DNV is a Class Guideline that provides guidance and requirements for the time-limited installation of containerised generator sets (CGSs) on board DNV-classed vessels.
DNV ensures safe and uniform interpretation of rules for using CGSs as temporary backup power, additional power (e.g., for reefer containers), or as a replacement for a damaged auxiliary or emergency generator. The guideline focuses on the individual integration of the CGS into the ship’s systems and its location on the vessel.

Key Aspects of the DNV-CG-0588:
- Purpose: To provide a comprehensive overview of requirements for installing CGSs for temporary use on ships.
- Scope: Covers the installation of containerised generator sets on DNV-classed vessels for time-limited applications, not permanent installations.
- Applications:
- Backup power in case of damage to a ship’s generator.
- Additional power for extra equipment like reefer containers or seismic equipment.
- Focus: Addresses the individual integration of the CGS within the ship’s systems and its placement on the vessel.
- Benefit: Aims to ensure consistency and provide clarity for ship managers, suppliers, and DNV in the installation of these temporary power units.
- Issuance: Superseded previous technical guidance from 2016 and was released by DNV, a leading classification society and technical advisor for the maritime industry.
