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 offshore wind power transmission platform

jorgemartiresElectrical engineering, Hazard analysis

MAR Consulting performed an Electrical Hazard and Operability (EHAZOP) analysis of an offshore wind power transmission platform. The platform receives AC power generated by wind turbines and distributes it to shore via a High Voltage DC link. Objectives of the EHAZOP The main 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 offshore wind power platform The E-HAZOP covered the high-power transmission systems: Gas Insulated Switchgears (GIS), transformer, […]

FMEA of electrical and control systems in subsea BOP

jorgemartiresElectrical engineering, Failure mode analysis, Reliability, availability and maintainability analysis, Safety and reliability engineering, Subsea engineering

MAR Consulting facilitated and documented an FMEA of electrical and control systems of a major drilling contractor’s subsea BOP. Purpose of the FMEA MAR Consulting facilitated the failure mode, effects and criticality analysis (FMECA) based on the methodology described on international standard IEC60812. Since it also included analysis of diagnostic capabilities, it could also go by the FMEDA designation (failure mode, effects, and diagnostic analysis). However, the purpose was significantly different than most FMEAs. Typically, an FMEA evaluates a design with the objective to unveil its weaknesses (and strengths). As a result, this information can form the basis of a […]

FMECA electrical and control systems in subsea BOP

jorgemartiresElectrical engineering, Reliability, availability and maintainability analysis, Safety and reliability engineering, Subsea engineering

MAR Consulting facilitated and documented an FMECA of electrical and control systems of a major drilling contractor’s subsea BOP. Purpose of the FMECA MAR Consulting facilitated the failure mode, effects and criticality analysis (FMECA) based on the methodology described on international standard IEC60812. However, the purpose was significantly different than most FMECA workshops. Typically, external resources perform an FMECA to evaluate a design with the objective to unveil its weaknesses (and strengths). As a result, this information can form the basis of a cost-benefit analysis for design improvement opportunities. In this project, however, in addition to the above, the drilling contractor/operator will use […]

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 […]

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.
