In practise, many of the housings and bulkhead penetrators will have a safety factor included in their design. You are simply operating beyond the stated "service depth". Whilst this may be fine for some manufacturers (some will manufacture to a 50% safety pressure vessel design), others may only use a margin of 10% - I suspect your technical manager has spoken to Forum and got a conservative estimation of that margin.
In that regard, I can't see any issue with insurance claims in the event of something going wrong - you're likely operating under instruction and (I suspect) in accordance with guidance from manfufacturer. I'd take a hard copy of that email though !!!
Kudos to you. Takes cah-hone-ays.
