But it doesn't say the BSC becomes automatically invalid, in such circumstances.
If it did, would it immediately be revalidated when it becomes compliant again? Or is another examination required?
And at what level of non- compliance does the BSC become invalid? If an essential gas pipe clip breaks and is fixed a week later, is it without a valid BSC for that week, for all time or is that defect below some undisclosed threshold?
In my estimation, unless the BSC is more formally withdrawn, it remains as such it is just that the vessel is non-compliant and quite possibly seriously or dangerously so.
