ApprovalApproval in principle◦ Approval of the concept◦ HMD, MAN & Alfa Laval drawings◦ Not explicitly required

HAZID◦ Component failure modes and effects◦ Detailed◦ Required for Flag State Approval

Flag state approval◦ Based AiP & HAZID◦ Owner’s responsibility◦ Subject to final approval by Class

Class approval◦ Yard is formal customer◦ Owner’s out of the loop◦ Site office – site team

Approval in principlePurpose◦ Proof of concept◦ Identify show stoppers◦ Speed up development◦ Basis for Flag state approval

Documentation◦ General arrangement◦ MAN concept drawings and philosophy◦ Cargo and fuel piping◦ N2 and cargo vent system◦ Sealing oil system

Pending issues◦ Same level of detail as full class approval◦ No major show stoppers◦ N2 connections, dangerous zones, drain system etc.

HAZID

Scope◦ Cargo system & service tank◦ LFSS and FVT◦ Drain and purge◦ N2 system & ventilation system◦ External influences

Principle◦ What if?◦ Cause and effect◦ Criticality and control◦ Very detailed; each and every valve, pump etc.

92 items, no major show stoppers

Three high risk items◦ Ensure filter drains are fitted◦ Proper procedures for tank entry◦ Save all to control leakage from service tank drain pipe

“A Failure Mode and Effects Analysis (FMEA) is a qualitative reliability technique for systematically identifying and analysing failure modes and their consequential effect within a given system. A Criticality Analysis (CA) is a quantitative procedure which ranks failure modes according to their frequency of occurrence and consequences (i.e. their risk).”
