Offshore engineering is safety-critical: installations combine hydrocarbons, complex machinery, harsh environments and people working far from help. This course covers safety engineering, risk assessment and hazard management for offshore structures and operations. It explains why offshore engineering demands a dedicated focus on safety, how safety is defined, and how the offshore operating context and project life cycle shape safety work. It then sets out the regulatory and legal framework, from international conventions and IMO to European directives and national regimes with safety cases and state supervision, and uses the bow-tie model as a unifying philosophy. Human factors and safety culture are explored through models of human performance and error, barrier models and the safety culture maturity ladder. Finally, the course covers risk management, quantitative risk assessment, the ALARP principle, risk acceptance criteria, safety studies and the hazard and effect management process.

Inside the course: a high-level summary, section by section.
Foundations of offshore safety
The course begins by asking why safety deserves a dedicated course. Working definitions of safety move away from the idea of zero risk towards the achievable goal of managed, acceptable risk, a philosophy that underpins the entire course and later reappears as ALARP. Almost nothing in engineering, and certainly nothing offshore, is completely free of risk, and the professional discipline lies in identifying, understanding and controlling it.
Offshore engineering is safety-critical because of the combination of flammable hydrocarbons, high pressures, heavy lifting, confined spaces, remote locations, harsh weather and limited escape routes. A short history of offshore oil and gas shows how major accidents have shaped regulation and practice. The offshore operating context balances economics, shared use of sea areas with shipping, wind farms, fishing and cables, and environmental protection, with several stakeholder groups whose interests must be weighed. The project life cycle, from concept and design through construction, operation and decommissioning, shows where safety decisions have the greatest influence, which is usually early in design. Challenges past and future, including ageing assets, energy transition and new technologies, complete the introduction.
Regulatory and legal framework
Regulation matters to engineers because it makes good safety practice mandatory, not merely good advice. The course explains the layered structure of regulation. The international layer includes United Nations conventions on the law of the sea and the work of the International Maritime Organization for ships and mobile units. The European layer includes directives that set requirements for equipment, the so-called hardware, and for working conditions and management, the software. National regulation is illustrated by the Dutch system, where operators prepare safety cases and the state supervisory authority for mines oversees compliance with defined powers.
The bow-tie model is presented as a regulatory philosophy as well as an analysis tool: it links threats, a central top event, consequences and the preventive and mitigating barriers that manage them. International regulatory cooperation and a case study of a real onshore incident illustrate how regulators and operators work together and learn from events.
Human factors and safety culture
The human factors section challenges three common misconceptions about safety management and distinguishes personal safety, such as slips, trips and falls, from process or operational safety, which concerns major accident hazards. A good personal safety record does not guarantee process safety. Risk perception often differs from actual risk, affecting decisions by workers, managers and the public.
Rasmussen’s skill-rule-knowledge model explains different levels of human performance and the types of error associated with each. A human error taxonomy distinguishes slips, lapses, mistakes and violations. The hazard-barrier-target model and the Swiss cheese model show how accidents occur when weaknesses in several barriers line up. The safety culture maturity ladder describes how organisations progress from pathological and reactive cultures towards proactive and generative ones. The section also warns about overconfidence in regulation and expert judgement, before a closing synthesis.
Risk management, QRA and ALARP
The risk management cycle covers hazard identification, risk assessment, risk reduction, monitoring and review. Expectation value is explained as the product of probability and consequence, together with the reasons humans find it difficult to reason about low-probability, high-consequence events. Black swan events, which lie outside normal expectations, are discussed as a limit of quantitative methods.
The ALARP principle requires risks to be reduced as low as reasonably practicable, meaning that further risk reduction is required unless its cost is grossly disproportionate to the benefit. An everyday illustration helps convey ALARP decision-making. Strategies for demonstrating safety include compliance with codes, good practice, risk assessment and engineering judgement. A case study of a process fire affecting an accommodation module on a floating production unit shows how layout, barriers and emergency response interact.
Risk acceptance criteria and the suite of safety studies, such as hazard identification, fire and explosion analysis, escape and evacuation analysis and quantitative risk assessment, are introduced. The hazard and effect management process provides a structured framework for identifying hazards, assessing them, controlling them and recovering from incidents. Risk metrics used in practice, such as individual risk and potential loss of life, and the formal ALARP region are explained, and the course closes with concluding risk-management principles.
Why this matters in practice
Engineering decisions made early in a project, such as layout, separation distances, material choices and barrier design, determine much of an installation’s lifetime risk. Engineers who understand regulation, human factors and risk assessment can contribute to safer designs, prepare and review safety cases and support a healthy safety culture. These skills are equally relevant in oil and gas, offshore wind, carbon capture and storage and other emerging offshore industries, where the same principles of barrier management and ALARP apply.
