IMCA has published Safety Flash 18-22.
Flash fire on Oxygen gas quad hose
There was a flash fire on an Oxygen hose line onboard a DSV. The incident occurred during routine checks, when an LST (Life Support Technician) reported that the Oxygen supply pressure to dive control was low (25 Bar). SAT control informed Dive Control and agreed that a new Oxygen supply was required. The LST went to the appropriate quad (on the main deck), and started by closing the row of eight bottles of Oxygen before opening a new row.
Damage to flexible riser
During deployment of a water injection riser from a vessel, damage to the outer coating occurred when it came into contact with the sharp edge of the flare in the moonpool area. A water injection riser was being installed through a project-supplied flare in the moonpool via the vessel’s Tiltable Lay System (TLS) at an angle of 6.8°. The flare had been designed to direct and protect the riser at the exit. However, design reviews, subsequent risk assessments and inspections had failed to identify the hazard of the sharp upper lip of the flare with the potential to damage the riser.
