In setting lithium-ion battery (LIB) Safety Standards Japan thoroughly tests land, ship and submarine LIBs. Above see a drop impact tester (on left) and vibration tester (on right). Photo courtesy Japan Industry News.---
Anonymous commentedabout Japanese Industrial Standards on lithium-ion batteries (LIBs) for ships. These Standards have requirements and recommendations on LIB safety.
[What are some examples of some Japanese maritime LIB safety standards by code and numbers? For more general Japanese Safety Standard for LIBs see subheading “Legal regulations in Japan”]
Safety analysis tools for risk reduction measures age equipment using LIBs include:
- Fault Tree Analysis(FTA)
- Fault Tree Analysis(FTA)
- Failure Mode and Effects Analysis (FMEA), and
- Safety Integrity Level (SIL)
Risks of LIBs for submarine are often pointed out. But submarine operation and maintenance involves many risks.
Risks of LIBs for submarine are often pointed out. But submarine operation and maintenance involves many risks.
For example the practice of rectangular “sunroof” hull cutting on Collins submarines (scroll 2/3s way down on this 2016 SubMatt article) to service diesel-generator sets) involves risk of fracture when Collins dive deeply. In fact the RAN leadership have limited maximum Collins diving depths because of the risks of extensive hull cutting.
It could be that the possibility of a submarine sinking caused by rectangular hull cutting is far higher than the risk of LIBs failure.
