MAP-01-011 – HFI Technical Guide (STGP 11)HFI Technical Issues• Machinery space layout feature (pipe work, lack of equipment save-alls,poor access to bilges for coating repair) that increase maintenancerequirements or make maintenance more difficult.• Passageway and accommodation space deck linings that require frequentupkeep.• Dirt traps created by exposed pipe and cable runs and equipment seats inpassageways due to poor installation detailing (e.g. inadequate cleaningenvelope).• Dust traps in ventilation system and poor air filtration.• Omission of save-alls on equipment to prevent working fluidscontaminating the bilges.Many of these issues may be prevented by the application of Def Stan 08-123‘Requirements for the Design and Testing of Equipment to Meet EnvironmentalConditions’ [Ref 27].Platform maintenance requirements can strongly influence the required level ofmanning and problems created by difficult maintenance tasks or highmaintenance workload may exacerbate health hazards and degrade ship safety.The way in which maintenance tasks are designed and arranged, and theresulting workload, can contribute significantly to the complementing requirement(Chap 4). Maintenance and ship husbandry requirements must therefore becarefully controlled.Figure 16-2: A platform maintenance taskNov 2006 Page 16-4 Issue 4
