Industries

Nuclear

Nuclear power is one of the alternatives for generating electricity. The nuclear industry which supports power production involves a full fuel cycle including:

• Uranium Mining and Milling
• Enrichment Fuel Fabrication
• Power Production
• Transport and Storage of Fuel
• Reprocessing/disposal

 Specialist services provided to the Nuclear Industry include:

• Various Safety and HAZOP Software
• Hazard identification and analysis Risk assessment (deterministic and probabilistic)
• Safety case preparation Safety management systems
• Emergency arrangements
• Licensing and authorisation issues
• Ergonomics and human reliability
• Radiological protection and health physics
• Reliability analysis of safety systems
• ARM assessments

Oil & Gas

Operators of oil and gas exploration and production installations face the dual challenge of achieving the maximum possible economic return whilst reducing the risk to personnel, plant and environment to acceptable levels. Operation in the offshore environment presents particular obstacles to satisfy both these objectives and there are several pieces of legislation specific to the industry which must be satisfied. Reliass can help in managing risk, satisfying legislation and maximising plant production.

Reliass can provide the following services relevant to the production of a Safety case to satisfy the:

• Offshore Installation (Safety Case) Regulations (1992)
• Appraisal of Safety Management Systems
• Systematic Identification of Major Accident Hazards – HAZOPs or FMEA
• Identification of Hazard Sequences resulting in Major Accidents
• Hazards Human Factors – Procedures/task analysis and human error probability estimation
• Consequence assessment supported by our integrated Consequence Analysis Software.
• Assessment of frequency of fault sequences/failure combinations: – ETA FTA
• Reliability data collection and analysis Escape, Evacuation and Rescue (EE&R) studies, for
• example EE&R HAZOP
• Uncertainty analysis using stochastic simulation to identify confidence predicted results As Low as Reasonably Practicable (ALARP) studies

Power

Reliass will provide support to operators and design contractors of both conventional and nuclear power plants. This support ranges from reliability and availability issues through safety studies to environmental aspects.

The types of activities undertaken are:

• Provision of Availability Modelling, Reliability, and Safety Software
• Availability modelling of power stations and distribution networks — using availability simulation software or bespoke solutions
• Reliability analysis of critical systems
• Hazard identification
• Safety case preparation
• Environmental release modelling
• Environmental impact assessment
• Contaminated land

Rail

The rail industry has revived worldwide after a period of decline, due to the need to solve the problems of road and city congestion and pollution, whilst meeting the world’s increasing transportation requirements and public expectations of safety and environmental performance. This has led to the development of new lines (both high speed and underground) and a resurgence of light rail and tramway systems. The need to reduce unit costs has led to increased single manning, de-staffing and automation. Of these changes can affect safety, the environment and operational performance and hence require sound risk management advice.

Reliass has specialisations directly relevant to these newly created businesses:

• Safety case preparation
• Quantified risk assessment
• Loss modelling
• Project risk assessment
• RAMS studies
• Value engineering
• Environmental Impact assessment
• Contaminated land assessment
