About Naavra for chemical tankers
Is the tanker pack included?
A chemical tanker needs everything in the tanker pack, so the planner adds it with the chemical pack and says why.
Does it decide whether we accept a cargo?
It checks the nomination and shows you what it found. People accept cargo; the check makes sure nothing is missed.
Can the charterer see the wall-wash result?
Yes. The pass or fail, with its photos, goes to the charterer on a link you control.
Does it cover CDI?
Yes. The CDI questionnaire sections, with evidence linked from the record, observations and closure.
