Safety Cases and Formal Safety Assessments

Our clients gain access to unrivalled reputation in preparing Safety Cases and FSA studies for all types of facilities including fixed platforms, Floating Production, Storage and Offloading vessels (FPSOs), Mobile Offshore Drilling Units (MODUs), construction vessels, flotels, pipelines and onshore MHFs. We ensure that the development of Safety Cases are compliant with regulations, guidance and industry accepted codes and practices, which can include safety surveys and audits.

In 2023, AGR and Add Energy‘s Well Management & Well Engineering teams joined forces. With combined operational expertise spanning over 70 years, we have created a knowledge heavy partner for our clients around the globe.

Our comprehensive Safety Case development plan is meticulously crafted to align with the Client’s schedule, incorporating ample time for Safety Case development, Client feedback, and regulator review and acceptance.

Drawing from design specifications, drawings, manuals, and surveys, our team, comprising engineers adept at extracting relevant information, produce concise Facility Descriptions.

Facilitating HAZID and ALARP workshops, we provide pre-populated worksheets based on our extensive experience with similar facilities. Leveraging assumptions, agreed input data, proprietary software, and in-house specialist tools, we conduct various FSA studies (FERA, NFHA, ESSA TRIA, SGIA, EERA, QRA).

Furthermore, we compile ALARP demonstration arguments, integrating key design decisions, workshop outcomes, FSA studies, and brainstormed risk reduction measures. Our expertise extends to crafting Company Safety Management System (SMS) descriptions that meticulously address regulatory requirements.

Before submission, we conduct thorough checks to ensure alignment with regulations. Additionally, we support the Client in addressing regulator queries and updating the Safety Case as needed.

Our capabilities include:

• Smoke and Gas Ingress Assessment (SGIA)
• Temporary Refuge Impact Assessment (TRIA)
• Dropped Objects Assessment
• Quantitative Risk Assessment (QRA)
• Ship Collision Risk Assessment
• Escape, Evacuation and Rescue Analysis (EERA)
• Emergency Systems Survivability Analysis (ESSA)
• MAE Summary Registers
• Bowtie Diagramme
• ALARP Demonstration

Safety Critical Elements and Performance Standards

As part of the Safety Case process, defining Safety Critical Elements (SCEs) and their associated Performance Standards is essential. We excel in crafting comprehensive Performance Standards customized for each operator or facility, prioritizing functionality, reliability/availability, and survivability requirements for each SCE.

Clients can expect to receive written Verification Schemes outlining how the Performance Standards will be achieved and how the performance of SCEs will be assured. This may include methods such as performance testing, Quality Assurance (QA) checks, inspections, and routine maintenance.

Facility Safety Surveys and Audits

Our experts perform safety surveys and audits to highlight any major safety concerns prior to committing to a Safety Case. This is normally performed in conjunction with a gap assessment against the latest Codes, Standards and Legislation. We also conduct surveys/audits to confirm compliance with the Safety Case and hazard register.
