Overview

HAZOP is a HAazard and OPerability study. This is a structured and systematic examination of a complex planned or existing process and operations, in order to identify and evaluate problems that may create risks to personnel or equipment. The intention of performing a HAZOP is to review the design and engineering or processes issues that may otherwise not have been found.

HAZOP.EU is a renown leader, proof-tested at working in extremely agressive, corrosive and flammable environments, both onshore and offshore. Most important sectors: oil and gas, pharmaceutical and chemical, various types of dust and bio fuel, ammunition warehouses, other applications.

SERVICES

Technical inspection

There are three levels of Hazardous Area Inspections. Detailed hazardous area inspection is the most advanced and complex check procedure.

Explosion protection

Mandatory for companies where potentially explosive atmospheres are likely to be present. European Directive 1999/92/EC (ATEX 137).

Hazardous areas

Classification. According to ATEX directive IEC 60079 explosive environment can be accumulated by explosive dust, gases and vapours.

HAZOP study

The intention of performing a HAZOP study is to review the design and engineering or processes issues that may otherwise not have been found.

SIL assessment

SIL defined and explained in standard IEC 61511. Generally speaking this is a safety performance measuring system.

SIL verification

The method of calculating the average probability of failure. Based on the IEC 61508 SIL’s are defined form SIL4 to SIL1.

Technical inspection

Detailed hazardous area inspection is the most advanced and complex check procedure.

ATEX / IECEx

ATEX consultations and training. Process and human safety in potentially hazardous areas.
