“…These LOPA results are in overall agreement with a previous QRA study of a hydroxylamine production facility [23], where the frequencies of hydroxylamine runaway decomposition calculated using fault tree analysis in the reactor and in the distillation column were 3.2 × 10 −6 /year and 9.5 × 10 −6 /year, respectively [23]. With only critical events and components considered, the LOPA results were consistent with the fault tree results to within an order of magnitude and required much less effort.…”

“…Past experiences of onshore and offshore oil and gas activities have revealed that a small mis-happening in the process operation might escalate to a catastrophe. This is of particular concern especially in the offshore platform due to the limited space and compact geometry of the process area, less ventilation, and difficult escape routes (Krishna et al 2003). In the onshore sector a refinery plant located near a coast line or a port is engaged with marine related activities such as transportation of the products by pipelines or tanker ships via oil terminals therefore, it will be categorised under the marine industry sector.…”

“…Risk evaluation involves the development of an overall estimation of risk by gathering and integrating information about scenarios, frequencies and consequences, and it is one major component of the whole RM process of a particular enterprise. In the process of risk evaluation, both qualitative and quantitative techniques can be used (Krishna et al 2003). However as ABS (2003) discusses the word risk itself specifically is the product of frequency with which an undesirable event is anticipated to occur and the impact of the event's outcome.…”

In the marine industry although there has been significant growth towards safety, security and risk assessments or risk-based strategies such as marine insurance and regulations to avoid the risks of damage to properties and the environment or the prospect of premature death caused by accidents etc, the moves toward managing the risks which are linked directly to the business functions and decision making processes have been very slow. Furthermore in the marine industry most perceptions, methodologies and frameworks of dealing with hazards, risks, safety and security issues are for their assessment rather than their management. This trend reveals the fact that in different marine industry sectors such as logistics and shipping there is a lack of coherent risk management framework or methodology from which to understand the risk-based decisions especially for the purpose of design, construction, operation, management and even decommissioning of the marine related applications. On the other hand risk management is not yet viewed holistically in the marine industry in order to, for example, assign a right person, i.e. risk manager, who can act as a coordinator and advisor with responsibilities that are only specific to risk management. As a result this paper, by examining the present physical borders and risk-based activities in the marine industry, aims to propose an appropriate risk management methodology in addition to the emergent role of risk managers which will enable the industry users initially to become familiar with the concept of risk management at its holistic level. In the later stages this eventually can lead to development of risk management capabilities at an exclusive level and its integration into the marine industry functions in future.

“…In the process of risk analysis, both qualitative and quantitative techniques can be used [8]. Nowadays a variety of techniques are used for risk analysis including Physical Inspections, Organisational Charts, Flow Charts, Safety Review, Checklist Analysis, Relative Ranking, "What-if" Analysis, Preliminary Hazard Analysis (PHA), Hazard and Operability Study (HAZOP), Failure Modes and Effects Analysis (FMEA), Fault Tree Analysis (FTA), Event Tree Analysis (ETA), Cause-Consequence Analysis (CCA), Human Reliability Analysis (HRA) [6,7,9,10].…”
