Fatal accident rates for offshore helicopters at nighttime and daytime (Nascimento et al, 2012) Darkness reduces both the actual efficiency of workers and their motivation and interest in their tasks (Freitag and McFadden, 1997). This, consequently, can increase failure probabilities or safety-concerned situations due to elevated human error rate.…”

Oil and gas (O&G) industry is expanding its activities into Arctic offshore, where is characterised with severe operating conditions and less-developed infrastructure. Such conditions affect the reliability, availability, and maintainability (RAM) of offshore O&G plants, operations, and activities through different scenarios. Plant RAM analysis provides key information for decision-making on, for instance, life-cycle cost management, inventory management, future investments, establishing maintenance policies, and safety-barrier management. Such decisions are of crucial value in Arctic offshore applications due to higher initial and operational costs. Therefore, a thorough evaluation and quantification of the effects of operating conditions on plant RAM performance play a significant role in such decisionmaking processes. In this regard, the aim of this paper is to broadly review and discuss different elements of offshore operating conditions specific to the Barents Sea, and further investigate various effects of such conditions on plant RAM. The present study can provide fundamental information to the academic and industrial sectors involved in the research and development of Arctic offshore O&G facilities and operations.

Analysis of helicopter accidents is fundamental to the development of effective mitigation measures. However, there are significant weaknesses in the current methods. This paper proposes a new structured framework for the analysis of accidents in helicopter operations, which includes the determination of the appropriate timeframe for analysis, establishment of terminological definitions, identification of the relevant accident variables and data sources, and the execution of a three-fold statistical analysis strategy. It is implemented in the context of worldwide offshore helicopter operations, enabling the identification of a number of areas for priority intervention including the need for a global harmonisation of accident data capture and dissemination, causal factor-based metrics for the calculation of accident rates, better pilot support for night-time and arrival operations, and a new safety paradigm to mitigate rare accidents. The framework is recommended for the analysis of helicopter accidents and incidents to support safety improvement.K E Y WO R D S 1. Accident analysis.2. Helicopter safety. 3. Predictive safety.

“…Well-discriminated phases of flight reflect analogous environmental hazards, aerodynamic loads, task complexities and pilot activities. Hence, phases of flight receive prime consideration during both the investigation of safety occurrences and the development of pilot training syllabi (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) . However, the phases of flight uniquely performed by helicopters are still poorly discriminated (5,15) because the current taxonomies are ill-adapted from fixed-wing operations (16)(17)(18)(19)(20)(21) .…”

“…This impacts on the quality of the safety data collected on a per-phase-of-flight basis (11,13,22) , thereby precluding the identification of specific problem areas. For example, changes in pilot control strategy associated with recurrent accident scenarios, such as the switch between visual and instrument scans during helicopter decelerating approaches in degraded visual environment (14,15,(23)(24)(25) , are still reported inconsistently in formal investigations. This is aggravated by the persistent absence of pilot demographic analysis which could improve understanding of pilot-related events during high-risk phases of flight.…”

Night-time offshore helicopter operations: a survey of risk levels per phase of flight, flying recency requirement and visual approach technique

et al. 2015

The analysis of risks per phases of flight is fundamental for safe helicopter operations, of which night-time offshore oil-and gas-related missions form an important part. The safe execution of such missions also depends on pilots' recent flying practice and a stable visual approach segment prior to landing. However, the poor quality of the safety data currently available prevents accurate analysis of risk on a per-phase-of-flight basis, establishment of a meaningful flying recency requirement and identification of any preferable visual approach design. To redress these problems, this paper develops a bespoke taxonomy of phases of offshore helicopter flights and uses it as the basis for a questionnaire survey on the phase-specific risk levels experienced by pilots in the night-time,
