- Abstract
- Maritime safety culture is currently one of the most important aspects of shipping. It enables maritime administrators to assess and manage safety-related issues proactively. However, most maritime organisations have not been able to effectively assess and manage safety-related issues proactively because of the challenges associated with the availability of safety performance data and the suitability of correlational statistical techniques used in safety culture assessments. Hence, researchers and professionals constantly debate which correlational statistical technique would be most suitable for assessing safety culture. This thesis aims to contribute to safety culture assessment from a methodological perspective of developing a decision-making framework for assessing maritime safety culture. Therefore, this PhD study offers an original contribution to knowledge regarding the application of decision-making techniques in a way that researchers have not previously done in assessing the safety culture of maritime organisations with commercial cargo-carrying vessels. Consequently, the integrated decision-making methodology adopted for this study entailed: the application of Analytical Hierarchy Process (AHP) in establishing weightage and priority setting of safety factors used in further assessments; the application of Simple Additive Weighting (SAW) in establishing the weighted safety climate performance of both shoreside staff and shipboard staff; the application of Pareto analysis in justifying the findings of the weighted safety climate and gaining insights into issues concerning occupational health and safety, ship safety, and shore-to-ship safety; and the application of Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) in scheduling vessels for safety culture improvement programs. The established weightage and priority setting of safety factors are: COMMUNICATION (COM) 0.15, EMPOWERMENT (EMP) 0.13, FEEDBACK (FDB) 0.11, MUTUAL TRUST (MTR) 0.11, PROBLEM IDENTIFICATION (PID) 0.13, PROMOTION OF SAFETY (POS) 0.12, RESPONSIVENESS (RSP) 0.11, and SAFETY AWARENESS (SAW) 0.14. Subsequently, the weighted safety climate performance of shoreside staff were: (COM) 0.651, EMPOWERMENT (EMP) 0.528, FEEDBACK (FDB) 0.418, MUTUAL TRUST (MTR) 0.365, PROBLEM IDENTIFICATION (PID) 0.543, PROMOTION OF SAFETY (POS) 0.451, RESPONSIVENESS (RSP) 0.448, and SAFETY AWARENESS (SAW) 0.515; while those of shipboard staff were: COMMUNICATION (COM) 0.570, EMPOWERMENT (EMP) 0.523, FEEDBACK (FDB) 0.432, MUTUAL TRUST (MTR) 0.419, PROBLEM IDENTIFICATION (PID) 0.517, PROMOTION OF SAFETY (POS) 0.458, RESPONSIVENESS (RSP) 0.441, and SAFETY AWARENESS (SAW) 0.601. Furthermore, Pareto analysis revealed that amongst all the feedback statements reviewed, MUTUAL TRUST (MTR) represents 30% of the safety factors attributed to feedback statements that are responsible for 70% of the least performing safety factors found in the weighted safety climate of shipboard staff, while PROMOTION OF SAFETY (POS) and PROBLEM IDENTIFICATION (PID) represent 30% of the safety factors attributed to feedback statements that are responsible for 70% of the least performing safety factors found in the weighted safety climate of shipboard staff. Finally, the TOPSIS methodology was applied to provide maritime administrators with a vessel's ranking, from the least performing to the most performing, for safety culture improvement programs as follows: MT DIDI (0.0908), MT SEA ADVENTURER (0.1124), MT SEAS GRACE (0.1726), MT UMBALWA (0.1815), MT SEA PROGRESS (0.2307), MT SEA VOYAGER (0.3816), MT ASHABI (0.4693), MT MOSUNMOLA (0.5365), MT AMIF (0.9243), and MT KINGIS (1.0000). Conclusively, this thesis adequately demonstrates how decision-making techniques can be simply and successfully applied in assessing the safety culture of maritime organisations without encountering the challenges associated with the availability of safety performance data and the suitability of correlational statistical techniques. It also demonstrated how safety culture could be assessed and managed like other areas of the organisation and business: thereby making safety culture more assessable to continuous improvement programs of maritime organisations with commercial cargo-carrying vessels.
