EHAZOP wind power onshore station

jorgemartiresElectrical engineering, Hazard analysis, Hazard identification

MAR Consulting performed an Electrical Hazard and Operability (EHAZOP) analysis of an electrical onshore station for a major OEM. The station receives power generated from offshore wind turbines (North Sea). The project was in the basic design phase, entering detailed design. Objectives of the EHAZOP The objectives were to: Evaluate the electric design with regards to safety and operability to avoid accidents and incidents; Ensure that design is fit for purpose and provides sufficient reliability, availability, and maintainability; Identify areas of improvement. Scope of the EHAZOP for wind power onshore station The E-HAZOP covered the high-power transmission and auxiliary systems. […]

Electrical SAFOP E-HAZOP LNG project

jorgemartiresElectrical engineering, Hazard analysis, Hazard identification, Safety and reliability engineering

MAR Consulting AS facilitated online a 7-day electrical safety and operability (SAFOP / E-HAZOP) analysis for a new liquified natural gas (LNG) development in the USA. SAFOP is also often referred to as an electrical hazard and operability (E-HAZOP) analysis. However, besides the technical system operability study, it can also include a more classical hazard identification (HAZID) and an operator task analysis. In this project, the client required system operability and a HAZID to identify potential hazards on the electrical design of the LNG plant. An operator task analysis was not included since the project was just entering the detailed […]

EHAZOP of power plant concept

jorgemartiresElectrical engineering, Hazard analysis

MAR Consulting performed an Electrical Hazard and Operability (EHAZOP) study of the electrical systems present in a power plant concept. Power Plant Concept The client wished to analyze a new power plant concept based on ultimate generation high-efficiency engines able to run on natural gas and heavy fuel oil. The engines are expected to run mostly on natural gas. Engine-based power generation will provide the flexibility necessary to counterbalance fluctuations caused by intermittent sources of energy into the grid, such as renewable energy sources. Objectives of the EHAZOP The EHAZOP focused on hazards potential resulting from the design, operation, and […]

Cybersecurity hazard identification

jorgemartiresCybersecurity, Hazard analysis

Cyber-attacks have the potential to become a major threat to oil and gas operators. Global ransomware damage costs are predicted to exceed $5 billion in 2017. That’s up from $325 million in 2015 — a 15X increase in two years and expected to worsen. Prevention and mitigation of accidents are normally achieved through good practices, hazard and risk assessments, and application of appropriate risk reduction measures. However, traditional process and hazard studies such as hazard and operability studies (HAZOP), hazard identification (HAZID), etc.. are not appropriate to address cybersecurity threats since they typically only consider single initiating events. MAR Consulting […]

Electrical SAFOP (EHAZOP) of US eLNG plant

jorgemartiresElectrical engineering, Hazard analysis

MAR Consulting AS facilitated an electrical safety and operability (SAFOP or EHAZOP) analysis of a unique North American liquified natural gas (LNG) plant. The LNG plant is being expanded with electric motor-driven technology for liquefaction resulting in reduced emissions and eco-friendly operations. An electrical SAFOP consists of hazard identification and safety analysis; system operability; and operator task analysis of the electrical systems in the plant. It is performed in workshops (3-weeks duration) with the system and electrical engineers; construction and commissioning personnel; and operators.
