On 28 September 2019, a cargo tank containing styrene monomer on board the MAIC (Maritime Authority of the Cayman Islands) registered chemical tanker Stolt Groenland ruptured due to runaway polymerisation. The catastrophic rupture released a large quantity of vapour to the atmosphere, and it subsequently ignited. Fire-fighting efforts by the emergency services took over six hours and involved more than 700 personnel and 117 units of fire trucks, pumps and fire tugs.
The rupture of the styrene monomer tank resulted from a runaway polymerisation that was initiated by elevated temperatures caused by heat transfer from other chemical cargoes. The elevated temperatures caused the inhibitor, added to prevent the chemical’s polymerisation during the voyage, to deplete more rapidly than expected. Athough the styrene monomer had not been stowed directly adjacent to heated Continue reading “Cargo tank explosion and fire on chemical tanker Stolt Groenland report published”
