Ensuring Safety & Risk Control
Comprehensive Process Hazard Analysis (PHA)
Diasozo is able to offer Process Hazard Analysis studies, PHA studies including Hazard and Operability studies, HAZOP studies, and as part of the risk analysis process detailed in IEC 61508 / 61511 (Phase 1).
A HAZOP study is a structured brainstorming session, set up to identify and evaluate the potential undesirable events that may create hazards or operability problems (i.e. risk to personnel and potential damage to assets, the environment, and the reputation) of the plant / site.
Each HAZOP study will be lead and facilitated by one of Diasozo several experienced HAZOP Chair, who have significant experience in carrying out a several HAZOP studies for both onshore and offshore projects in recent years and fully understand the requirements for delivery of the HAZOP scope of work

As well as a HAZOP study, there are a variety of PHA techniques which Diasozo is also able to offer:
HAZID Identification
SIL Verification
SIL Determination
RAM Studies
Functional Safety Management
Quantitative Risk Assessment – QRA
Failure Mode and Effects Analysis (FMEA)
Hazard Identification (HAZID) study – a high-level hazard identification workshop which is normally held in the initial steps of a risk assessment and includes assessments of external event and hazards; Control Hazard and Operability study (CHAZOP) – reviews the design and operation of a control and safety system to identify potential hazards and operability problems. Is focused on how a control system or safety system deviates from the design intent; ‘What If’ Analysis – a structured brainstorming method of identifying the hazardous situations, sequences or abnormal situations and judging the likelihood and consequences of these occurring and the existing safeguards that exist to prevent them, leading to alternative suggestions on how to provide risk reduction where improvements can be made or where safeguards have been deemed to be inadequate.
