HSE Cases, Studies, Audits and Inspections
In a safe, healthy working environment your team will work with confidence, knowing they are well cared for. As a result you will experience high productivity and very limited down-time due to incidents or accidents. Work will be done efficiently while all necessary procedures will be followed to ensure safety.
AdviSafe supports you in keeping ahead of incidents and accidents and providing your team with a safe, healthy working environment that stimulates productivity and ensures your continuity. We can support you with:
- Identifying the hazards and assessing the risks of your business activities or projects by applying the preferred methods for the situation (eg. HAZID, BowTie, HAZOP, RIE, LOPA FME(C)A, SIL);
- QRA and associated safety studies to develop HSE cases;
- Determining HSE Critical Systems, definition of Performance Standards and Verification Schemes;
- Development and/ or review of (integrated) HSEQ management systems;
- Demonstration of risks being As Low As Reasonably Practicable (ALARP);
- Documentation of all of the above according the required format in as less possible pages.
Our expertise typically originated from the Oil & Gas Industry but has gradually extended to a broad range of industries eg. Petrochemical, Logistics, Power generation, Construction, Marine etc. Our HSE consultancy expertise and services cover:
- HSE Cases;
- HSE Studies;
- HSE Audits & Inspections.
AdviSafe can support and advise on the duties of your HSE management in preparing the (Project) HSE case. We can actively support you in defining the project goals and objectives, as well as the precise activities needed to achieve them. Subsequently, we can support the assigned personnel to conduct or manage the activities described in the (Project) HSE case. Activities may typically include hazard identification and risk assessment studies, reliability analyses, hazard and operability studies, input to contract documents, review of project deliverables, review of vendor bid documents and the maintenance of an HSE Issues Tracking System.
We are familiar with legislative requirements both national and several foreign countries.
In order to compile the HSE Case, a number of activities need to be undertaken. The building blocks are briefly described below. The studies may already commence in the Design Engineering Stage but need to be completed in time for submission of the HSE Case:
Update of Safety Philosophy
Final review and update of Safety Philosophy, include operational aspects.
A HAZard IDentification study will be carried out to ensure all major accident hazards associated with the design envelope have been recognised and identified.
HAZOPs are to be carried out on all processing systems/topsides, marine, utility and safety systems.
Reliability and Availability Studies
Calculations will be undertaken to determine the reliability and availability of the essential systems on the installation. The results will be verified against the performance standards set in the Safety Philosophy. The results will be used in the Safety Studies and Quantitative Risk Assessment.
Fire and Explosion Risk Assessment
National guidelines will be used together with national regulations in which the use of the FERA is described. This assessment will identify and assess the credible fire scenarios and their consequences.
Emergency Systems Survivability Analysis
For the essential safety systems (ESD, EBD, fire and gas detection, alarm, communication systems, emergency power and lighting and temporary refuge ventilation) an initial assessment will be carried out.
Evacuation, Escape and Rescue Analysis
Based on the identified hazard scenarios, the adequacy of the design on evacuation and escape features will be assessed. Similar to the FERA, the EERA has to demonstrate compliance with the PFEER regulations.
Temporary Refuge Impairment Study
This study will review the integrity of the TR under accident conditions. The ingress of combustion products and gas and the temperature increase inside the protected space will be calculated and judged against the performance standards.
Quantitative Risk Assessment
This study will calculate the risk levels on the installation and will show how these risks are distributed. This will assist in identifying further risk reducing measures which will be assessed in the ALARP study.
In order to demonstrate that the design of the installation is in accordance with the ALARP principle, Cost Benefit Analysis will be carried out. When the risk reduction is disproportionate to the additional costs, the ALARP principle is considered to be fulfilled.
An ergonomic assessment study will be undertaken. In particular the control room layout, access, egress and process control device operations and functions will be assessed.
An environmental impact assessment will be undertaken. The study will be focused to assess and demonstrate compliance with the legal requirements.
Operability and Maintainability Study
Review the operability and maintainability of the installation. Looking at material handling and transfer throughout the entire installation and modules.
On the basis of the existing documentation, predict the noise levels in the various areas. Comparison with the legislative and project requirements will determine possible problem areas where improvements are recommended.
Operating companies in the mining industry are required to carry out Health & Safety and Environmental studies in the different life cycle phases, eg. during the design of facilities, as well as prior to construction, during operation and when abandonment is imminent. We have executed safety studies regularly over the years for many companies in the oil & gas industry, as well as other industry sectors. We can perform various kinds of HSE studies, such as:
Hazard Identification (HAZID)
The major benefit of HAZID is that early identification and assessment of the critical HSE hazards provides essential input to project development decisions. Assessment is actually the next step which is normally combined in the same session (HIRA) Checklists, hazard registers from similar activities and previous HAZIDs are frequently used in order to assist in the task of hazard and consequence identification.
Once the list of hazards has been established, each hazard is then classified, normally using a risk classification matrix. Dependent on the level of risk, mitigative measures are addressed accordingly.
Bowtie risk assessments are conducted in workshop settings using the BowTie methodology. BowTie uses a graphical interface to present bowtie diagrams (sometimes called butterfly diagrams). In a workshop setting, these diagrams are projected onto a screen for all attendees to see, brainstorm and review. The result is an overview of the hazards, unwanted events, threats, consequences and the way these are controlled by barriers. This can be fully linked to the existing management system or even be at the centre of it.
Hazard and Operability (HAZOP)
During the design of a new process installation errors and oversights are a common problem. A HAZOP study is an opportunity to correct these in the design phase of a project to prevent unsafe situations and costly corrective measures afterwards.
RI&E (Risk Inventory & Evaluation)
General Risk assessment and review of compliance with legislative requirements (typically for all companies in the Netherlands) including the formal review of RI&E.
Layer of Protection Analysis (LOPA)
This method can be used to assess the effectively and independency of the barriers you have in place in a semi-quantitative manner. It gives a more structured approach in assessing your risks before and after controlling measures.
Failure Modes and Effects Analysis (FMEA)
An FMEA provides benefits to both the manufacturer and the customer. A successful FMEA activity helps a team to identify potential failure modes based on past experience with similar products or processes, enabling the team to design those failures out of the system with the minimum of effort and resource expenditure, thereby reducing development time and costs. Additionally the criticality of components in the system can be determined.
Job Hazard Analysis (JHA) / Job Safety Analysis (JSA)
JHA/ JSA is a qualitative method of assessing risks associated with a particular job in order to decide upon the precautions and contingency provisions that should be taken to reduce the risks. Although the exact format of the evaluation may differ from company to company, the general approach involves breaking the job of activity down into a number of logical steps to be taken to accomplish the task. For each step, a number of questions are asked in order to identify hazards, consequences and risks associated with that particular step and the precautions and contingency measures that can be taken.
HSE Audits & Inspections
How do you determine the status of your HSE management system? The health and safety management audit is a structured process of collecting independent information on the efficiency, effectiveness and reliability of the total HSE management system and drawing up plans for corrective action. Auditing examines each stage in the HSE management system (system, compliance and effectiveness) by measuring compliance with the controls the organisation has developed, with the ultimate aim of assessing their effectiveness and their validity for the future.
The following types of audits can be facilitated and executed by us:
HSE management system audit (ISO 9001/ 14001/ OHSAS 18001);
(Project) Health, Safety & Environmental (HSE) auditing;
Technical audit/ inspection of installations;
Operational audit/ inspection, “OOG” inspections; (Observation unsafe behaviour), PtW/TRA.
