NAVIGATOR OF THE SEAS TO FEATURE FIRST FIRE PREVENTION NOTATION

Thursday, June 6, 2019 

The new class notation F(M-P), the result of a joint industry project to improve engine room fire prevention initiated in 2016 by cruise operator RCL, Wärtsilä, and classification society DNV GL, will have its first reference with RCL’s new cruiseship Navigator of the Seas.

The new DNV GL class notation identifies key areas for preventing fires in engine rooms based on incident analysis, feedback from surveyors, and best practices from the industry. It sets in place standards and processes focussing on the prevention, detection and containment of oil leakage, the shutdown of system, as well as the prevention of ignition.

“The new notation brings together many aspects of barrier management to improve safety,” says Knut Ørbeck-Nilssen, CEO of DNV GL – Maritime. “It covers not just the technical systems, but the processes used and the people involved, utilising best practices to provide a holistic approach to preventing these incidents. This notation shows the importance of learning from casualty data, and how by combining this with the insights from class and the industry we can work together to move safety forward.”       

As casualty statistics indicate that many engine room fires occur when flammable liquid reaches a hot surface, the notation introduces process checks and technical measures to prevent this from occurring. There is overarching emphasis on both internal and external processes and procedures, with auditing of procedures to enable more efficient oversight.

Likely areas for leakage are identified, and containment strategies for such areas offered. Control and monitoring of vibration in essential systems is an added requirement, with ongoing data collection included to show trends over time. Insulation of potentially hot surfaces is also a key issue to prevent ignition, so maintenance activities in this area are emphasised. In addition, the requirement for continuous improvement through data analytics means that owners and operators can gain ongoing benefits from the processes and systems they put in place to prevent fires. 

“Our target is zero engine room fires and with these enhanced standards, we believe this goal is within reach,” said Anders Aasen, VP of Global Technical Solutions at RCL. “Any fire, even one that is detected and extinguished immediately, can impact not only the ship, but the operator and the whole industry. This is why we are so pleased that the cruise ship safety forum, alongside many other stakeholders, could come together around a set of best practices that strengthen safety barriers and were published in January this year. For RCL, this project has had the added benefit that we have enhanced our data analytics capabilities, which gives us an ongoing scope for further improvement.”
