Leading insurance broker Aon has warned shipowners that record-keeping will be critical in ensuring they are reimbursed for IMO 2020-related fines by their protection and indemnity insurers.

Aon issued a note to clients stating that P&I cover for such fines would only be paid out by clubs on a “discretionary” basis.

The broker said that the more a shipowner was able to prove it has made every effort to comply the more likely it is that P&I insurers would pay out.
