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”
The US Coast Guard (USCG) has published a safety alert to addresses the importance of verifying the condition and manufacturing of wire rope terminations that are used in various systems that utilize wire rope in a load-handling capacity (e.g., lifesaving appliances, cranes, lifting slings). The Coast Guard is currently investigating a casualty involving a failed wire rope termination that resulted in extensive damage to equipment.
The Coast Guard has observed that improperly applied swaged fittings could result in unintentional damage to the wire rope, resulting in failure of the termination. Improper swaging procedure includes failures within a quality management system in which materials are improperly selected and do not match the specifications of the original equipment manufacturer.
The Republic of the Marshall Islands (RMI) has published a Marine Safety Advisory notice. In it RMI stresses the importance of properly inspecting and maintaining all immersion suits, following a number of recent cases of defective equipment found onboard RMI flagged vessels.
Since 2019, when RMI shared a marine safety advisory focusing on the importance of following the manufacturer’s instructions for maintaining immersion suits, there have been multiple additional instances of defective or improperly maintained suits on RMI-flagged vessels, one of which resulted in a PSC detention by the US Coast Guard. In that case, “29 of 32 immersion suits were unserviceable due to unsealed seams,” and these suits were only five years old.
Guidance on the technology, systems and regulations needed for minimizing human presence on offshore facilities has been published by ABS. The whitepaper evaluates technology, regulations, systems and design issues. Reduced Manning on Offshore Facilities introduces some of the considerations essential for remotely operating floating facilities from a control center located nearby or onshore. To enable reduced manning without compromising safety, real-time monitoring, control automation and maintenance procedures incorporating remote diagnostics and simulations with minimal human intervention will be required.
