There is no requirement for an aft peak bulkhead in the regs. It is optional. The forward collision bulkhead is a requirement.
Do you actually have one? Or are the tanks aft of the engine room bulkhead or engine room wall?
Typically a aft peak bulkhead would be just forward of the rudder stem and stern tube to isolate leaks coming from these two areas.
As there is no requirement for the bulkhead there is no need to describe it as such.
My fuel tanks (and I suspect most other peoples') are situated at the rear of the ship and I have no aft bulkhead (between the engine-room and accommodation). This disqualifies the ship from the Rhine but otherwise was not a problem for the Certification in 2010 or re-Certification in 2017.
I have been reading through the requirements of the ESTRIN requirements and have a question for the experts.
My fuel tanks are situated at the rear of the ship and aft of the aft bulkhead, yet i note from the regulations it states that 3. No fuel tanks may be located forward of the collision bulkhead or aft of the aft-peak bulkhead.
Does this mean I have to have mine relocated, or is the 'aft-peak bulkhead' the forward bulkhead?
