Risk Analysis in the MRO industry (English)
Abstract [sv]

MRO-industrin är en kritisk del för underhåll inom flygindustrin och arbetsprocesserna ser olika ut från företag till företag. För att kunna utföra ett så säkert och kvalitetsmässigt arbete som möjligt så är det viktigt att riskbedöma samt minimera existerande risker i operationen för att säkerställa kvalitet till kund samt säkerhet för arbetare. Uppdragsgivaren ST Engineering Aerospace Solutions (STEAS) är det ledande företaget i Sverige när det gäller MRO arbete och med den ständiga utvecklingen av utrustning upptäcks det allt fler risker som kräver analyser och minimering.

Forskning har tidigare gjorts på hur fixtur design kan förbättras ergonomiskt m h a virtuell miljöteknik. Detta för att kunna minimera design och tillverkningskostnader med hänsyn till itereringsprocessen. Detta i kombination med studier gjorda på muskuloskeletala skador med kopplingar till MRO-industrin belyser behovet av riskanalys i MRO industrin.

Arbetet hos STEAS går ut på att utföra riskanalyser ur ett tekniskt, ergonomiskt och ekonomiskt perspektiv på deras rörliga fixturer samt kemiska processer som behandlar diverse komponenter av motornacellet. Detta för att STEAS sedan ska kunna kolla på eventuella kostnader och implementera de rekommenderade åtgärderna. Analysmetoderna som används är en PHL (Preliminary Hazard List), FMEA (Failure Modes and Effects Analysis) och en ACHB analys (Accidental Cost & Hypothetical Benefit)

Abstract [en]

The MRO industry is a critical part of maintenance in the aviation industry where the work processes differ from company to company. In order to be able to perform as safe and high-quality work as possible, it is important to assess risks and minimize existing risks in the operation to ensure quality for customers and safety for workers. The client ST Engineering Aerospace Solutions (STEAS) is the leading company in Sweden interms of MRO work and with the constant development of equipment, more and more risks are discovered that require analysis and minimization.

Research has previously been done on how fixture design can be improved ergonomically using virtual environment technology. This is to be able to minimize design and manufacturing costs with regard to the iteration process. This in combination with studies done on musculoskeletal injuries with connections to the MRO industry highlights the need for risk analysis in the MRO industry.

The work at STEAS consists of performing risk analysis from a technical, ergonomic and financial perspective on their moving fixtures and chemical processes so that STEAS can then check for possible costs and implement the recommended measures. The analysis methods used are a PHL (Preliminary Hazard List), FMEA (Failure Modes and Effects Analysis) and an ACHB analysis (Accidental Cost & Hypothetical Benefit)
