Future-proof vessels


The creation of the rules has allowed DNV GL to incorporate and integrate more modern tools, software and enabled us to build the rules to make them more responsive to future developments.

The future is electric

One of the technical highlights of the new DNV GL rules is the class rules for battery-driven vessels and large lithi-um battery systems. Complementing the existing rules for batteries introduced in 2012, the new rules will include a revised and improved version which also covers the use of batteries as a power source for dynamic positioning (DP) systems.

These rules cover the requirements relating to battery safety, the Battery Management System (BMS), the environment and tests. In addition, DNV GL offers a type-approval service for battery systems. This type approval will on a generic level verify that the battery system fulfils the DNV GL class rules’ requirements, including those relating to applicable type tests (safety and environmental tests).

The new DNV GL Rules for Dynamic Positioning (DP) systems stipulate requirements for the use of batteries as a power source. The batteries will represent a time-dependent source due to their limited stored energy. DP operations using batteries as one of the redundant sources are limited to operations that can be terminated within the timeframe represented by the batteries’ available capacity.
