The water in the bilge is pumped out on 28 June. The area then remains accessible and is checked repeatedly. This makes it easier to see whether new liquid appears and whether its amount or appearance changes.
Observe quantity and recurrence
Once empty, the bilge can be checked for renewed liquid and any connection with operation or conditions. That information helps determine urgency and the direction of further inspection.
Pumping begins the observation
Water is pumped from HERA’s bilge on 28 June, creating a clear starting level rather than ending the task. The area is dried and later checks are linked to time and operating condition. A change after engine use or sailing narrows the search. The rate of return determines urgency, while an automatic pump remains a safeguard rather than an explanation.
The real observation starts after pumping
Pumping removes the visible water and creates a new reference line. Drying the remaining film makes the entry point and rate of any new accumulation easier to recognise. Time alone is not enough; the crew also records what has happened aboard. A bilge that stays dry alongside but changes after engine use or sailing directs the search. Rapidly rising water or a visible inflow, however, ends observation as the only response.
Frequently asked questions
Is the problem solved after pumping?
Not necessarily. The liquid is removed, but the cause may still exist.
Why check an empty bilge again?
New ingress becomes visible sooner and can be placed more accurately in time.
When is observation no longer enough?
When the amount or development affects safety or cannot be controlled, further help is required.
