RFPEW assessments

Looking to sign off some assessments for a junior engineer on board. We are over 1000 HP and have a ‘walk-in’ engine room, and can’t see any other concerns over the vessel not meeting the requirements.

However, there are a few pieces of equipment that aren’t on board, therefore I can’t sign them off. i.e. oily water seperator…
Do I just put n/a in the box ? I found some old threads kinda regarding this but the main discussion was over steam. So I’m curious if not having an OWS and purifier (centrifuge) on board here creates a limitation?

You shouldn’t put N/A in the record of assessment. Whether or not it’s applicable is to be determined by the Coast Guard, not the assessor. Your putting N/A down will have no effect on whether or not it has to be done.

Should there be an explanation included on why something is left blank?
