"This book describes research on safety-related decision-making by operations supervisory personnel in three different high-hazard industries, and features a case study illustrating each: a chemical plant, a nuclear power station and an air-navigation service provider. The focus of this research is unique: those who supervise the frontline personnel and essentially provide the organizational link between senior management and minute-by-minute system operations"--Provided by publisher

The blowout of the Montara H1 well in the Timor Sea off the northwest coast of Australia in August 2009 was the first such incident in Australian offshore waters for 25. years. This article seeks to draw lessons for management of complex hazardous activities from these events by analysing critical decisions regarding well control barriers. Concepts such as trial and error learning, sensemaking and the need for multiple barriers are used to demonstrate why the organisation was blind to the developing problems and hence why lack of technical competence alone is not sufficient to explain the events that occurred. Three organisational improvements are proposed - providing active supervision, improved technical integrity assurance and better use of risk assessment. The article concludes with an appeal for changes in regulatory policy regarding safety to include organisational issues in addition to the traditional technical focus.

This open access book examines the increase in outsourcing, contracting and subcontracting as ways of organising work. It explores the impact of these employment arrangements on public safety, particularly when they are linked to complex supply networks in a range of engineering industries including oil and gas, nuclear power and aviation. The brief provides practical recommendations on how best to manage arrangements that target short-term profitability and also maintain excellence in long-term safety outcomes. The brief is a source of advice for organisations on how to maximise the benefits and minimise long-term system reliability issues that can be introduced by contracting and outsourcing, rather than assuming it to be a wholly negative or positive practice. Contracting and Safety comprises qualitative, empirical studies focusing on high-reliability organisation. As such, this brief provides a rich picture of the experience of working in complex supply chains. It will be of interest to researchers in industrial safety, as well as safety professionals and project managers within engineering industries.

AbstractWhile the literature on regulatory compliance is extensive, little scholarly attention has focused on how companies respond to conflicting regulatory requirements. As a case in point, gas pipelines and networks—deemed monopolies—are subject to economic regulation to emulate the price pressures of competition and encourage "efficient" expenditure. Technical (safety) regulation of the same infrastructure also addresses an expenditure trade‐off with safety, potentially drawing different conclusions as to the most appropriate balance. This article reports on a study—drawing on 49 interviews, document review and case studies—analyzing if these two regulatory regimes, as enacted in Australia, are in conflict. We find a significant tension between the two regimes, exhibited through the impact that economic regulation has on a company's planned safety‐related expenditure and thus, long‐term public safety outcomes may be at risk. Australian safety regulation is performance‐based, requiring "reasonably practicable" measures are in place to minimize risk to the public. The San Bruno California disaster, in which eight people died as a result of failed gas infrastructure in the US, shows that such regulatory conflicts also exist in jurisdictions that have adopted prescriptive forms of safety regulation.

AbstractThis paper examines the relationship between conceptual and embodied reasoning in engineering work. In the last decade across multiple research projects on pipeline engineering, we have observed only a few times when engineers have expressed embodied or sensory aspects of their practice, as if the activity itself is disembodied. Yet, they also often speak about the importance of field experience. In this paper, we look at engineers' accounts of the value of field experience showing how it works on their sense of what the technology that they are designing looks, feels, and sounds like in practice, and so what this means for construction and operation, and the management of risk. We show how office-based pipeline engineering work is an exercise in embodied imagination that humanizes the socio-technical system as it manifests in the technical artifacts that they work with. Engineers take the role of the other to reason through the practicability of their designs and risk acceptability.
