The Study Of Safety Risk Evaluation Model Of Stevedoring Operations At Tema Port Of Ghana Based On AHP

Ports play a critical role in the global supply chain,therefore strengthening the supply chain and port operations may reduce risk associated with stevedoring operation,thus the purpose of this study was to identify and evaluate preferred risk assessment alternatives which could reduce the risk during stevedoring of hazardous and dangerous cargo.The research explored stakeholder's opinions for alternatives to adapt to reduce operational risks by using the Analytical Hierarchy Process(AHP).The goal,criteria and alternatives were derived and stakeholders proposed measures to strengthen port risk control management.This study combined the SCOR model with the results of port enterprise supply chain risk,and divides the Tema Port SCOR risk evaluation into five modules according to the characteristics of port enterprise supply chain operations.These includes: Port Services System Risk,Dangerous Cargo Risk,Port Operation Personnel,Work Environment Risk and Plant & Equipment risk.A total of 128 respondents correctly filled and submitted the questionnaires out of a total of 150 questionnaires circulated,representing 85.3% response rate.Based on the weight of the main criterion layer,the index weights of Risks R1 to R5 were 0.080,0.366,0.068,0.399 and 0.087 respectively.The first risk indictor-Port Service System,the third risk indicator-Port Operation Personnel and the last risk indicator-Plant & Equipment were relatively lower.The results showed that dangerous cargo risk and environment risks are the criteria of highest priority.The highest priority alternative was preventing falls and falling objects(0.188),followed closely by dangerous cargo defect condition(0.153).The least preferred alternative was professional skills and training,closely followed by Repair work required during loading or unloading,with priorities of 0.003 and 0.006 respectively.The choosing the option preventing dangerous cargo defect is about 81% as good as the option of preventing falls and falling objects in reducing risk associated with stevedoring dangerous cargo.The CR was calculated from the pair-wise judgment matrices from each stakeholder group.The resulting CRs were all less than the 10% limit.To strengthen risks control,the stevedores suggested among others that port authorities and management should constantly improve distribution efficiency,reduce cargo defects,increase professional skills and try as much as possible to prevent falls and falling objects at the port.
