The Norwegian Hull Club is offering shipowners damage and loss of hire cover for exhaust gas cleaning systems, also known as scrubbers.

The move comes in response to technical concerns over the 4,000 ships that have either fitted, or are in the process of fitting, scrubbers to comply with the IMO 2020 regulation on global sulphur emissions.

There have already been widespread reports of breakdowns with the new technology, while there is a major question mark over who pays for the resulting losses.
