Part 6 Chapter 2 - Propulsion, power generation and auxiliary systems
The class rules cover the use of batteries as a part of the propulsion energy for vessels either by hybrid battery solutions or “pure” battery driven vessels. The rules have been developed from the tentative legacy DNV Battery Power rules from 2012.
This is new in the 2015 Battery power rules:
- Specific requirements for fire safety of battery spaces.
- Environmental control of battery spaces.
- Specific test requirements for batteries.
…and yes, you can use the batteries in DP operation.

Chapter 2 - Propulsion, power generation and auxiliary systems
Battery (safety)(a new notation in 2015)A notation that cover requirements for the safety of the battery installation covering vessel arrangement, environmental control including temperature and ventilation.
To prevent thermal incidents in battery spaces, then the rules gives requirement to fire integrity, detection and extinguish measures.

Chapter 2 - Propulsion, power generation and auxiliary systems
Battery (power)The notation you need when the battery is used as a main source of power (propulsion power).
The rules put requirements for redundancy and location. In addition the time or range that the battery can supply energy shall be calculated taken into account the planned operation/voyage

Sec.1.2 Design principles for Battery (safety) notation
The battery space shall not contain
redundant propulsion or steering systems
Safety assessment
– gas development risk (toxic,
flammable, corrosive)
– fire risk
– explosion risk
– necessary detection and alarm systems
(gas detection, fire detection etc.) and
ventilation
– external risks (fire, water ingress etc.)
– loss of propulsion or auxiliary power for
essential or important services.

Additional fire integrity requirements for notation
Battery (power)
Monitored by smoke detection within the spaces.
Water-based fixed fire extinguishing system.
Conformance and non-conformance with these
requirements shall also be included in the safety
assessment.

– available energy of the batteries
– remaining time or range that the battery can supply
energy for the planned operation/voyage
– state of health of the batteries (SOH)
