The Isle of Man Registry plans to send safety recommendations following the August 2017 fertiliser fire aboard Bibby Line's 57,000-dwt bulker Cheshire (built 2012).
The Red Ensign Group member investigated a fire involving ammonium nitrate-based fertiliser (ANBF) that rendered the the ship a "constructive total loss" (CTL).
The ANBF began to decompose early in its voyage from Norway to Thailand, the UK's Maritime & Coastguard Agency said.
