Following extensive communication with the reporters, CHIRP raised these concerns to the Flag State, the designated person ashore (DPA), and the Hull and Machinery Insurers.
This report illustrates the lengths to which some irresponsible vessel owners will go to circumvent regulations designed to protect the environment. This is likely because the cleaner fuel is more expensive, and the company puts profit over safety.
The incident also suggests that Flag and Port State inspections should be reviewed to ensure that such behaviours can be detected. Vessels admitting to carrying fuel exceeding the 0.5% limit should be required to demonstrate how they intend to reduce sulphur levels, either through a scrubber system or another method.
The exhaust gas cleaning system should only be considered a temporary measure, and ultimately, all ships should be converted to using low-sulphur-compliant fuel.
