The manufacturer’s instruction manual for Seven Seas Voyager’s waste incinerator contained no specific instructions for ash grate maintenance or replacement. Such instructions would have provided useful information for the ship’s crew to plan and safely complete periodic ash grate maintenance.
ISIR Impianti did not take any safety action. However, the ship's managers took proactive safety action that included amended planned maintenance system work orders for the incinerator and revised monthly inspection routines for the equipment. This action has reduced the risk for the manager's fleet and the ATSB has closed the safety issue as partially addressed.
The ATSB recommends that ISIR Impianti Srl take action to ensure that their equipment maintenance instructions contain all detail necessary to allow the safe completion of routine and non-routine maintenance activities.
