  Background and aims: ‏ Evaluation of the contractor’s HSE is a key issue for the employer that influences the selection of a contractor. An appropriate method of assessment can play a significant role in the selection of qualified contractors. This paper presents a new method for ranking of contractor’s HSE at pre-contract stage of a project.

  Methods: To develop this new evaluation method, the c ontracts were categorized in 3 groups of advanced, medium and preliminary. In order to pre-assess the contractors’ status prior to their participation in bids, an HSE data questionnaire was developed in the frame of 40 questions. Then 29 indices were developed for primary HSE assessment based on International Association of Oil and Gas Producers (OGP). Because the role of each index is different in each category of contracts thus, seven elements of HSE model were weighted on the basis of contract category. Contractors scoring system was developed in each category of contract based on the obtained weights. Finally the contractors were categorized in four groups of A, B, C and D based on their scores obtained from their HSE evaluation.

  Results: The results revealed that each term of HSE have different weight in each contract category. In advanced (group 1) and medium (group 2) contracts, the leadership plus commitment (coefficient of 4.9 and 4.3 respectively) and in preliminary contracts the execution and monitoring (coefficient 3.3) have the highest weights. The Strategy and goals have the minimum weight in all 3 types of contracts (e.g. 4.4 in advanced, 3.6 in medium and 2.4 in preliminary contracts). The minimum score required for an A group contractor to get an advanced contract is 537 while the maximum score of a D group contractor to obtain a preliminary contract is 123.

  Conclusion: The new developed method is able to rank the HSE of contractors prior to sign the contract.
