A vetting inspector observed that the minimum fuel quantity, marked on the diesel oil tank of the Emergency Generator, was not correct, since it was less than the minimum required by SOLAS for minimum 18 hours operation of the engine, taking into account the required electric load. C/E changed the marking as per inspector’s instructions which were, however, again incorrect since they had calculated the consumption at maximum load and not in accordance with the load stated in the load analysis.
Lessons Learned: In accordance with good practice the diesel oil tank of the Emergency Generator should always be kept almost full well above the minimum SOLAS required capacity.
The marking as described in the report is questioned as not being good practice. Keeping the tank full, rather than containing just the minimum amount, is recommended.
