Introduction MAR Consulting facilitated a Safety and Operability (SAFOP) workshop of the electrical equipment in an offshore wellhead platform for an ultra-HPHT (high pressure high temperature) gas condensate field located in the Central North Sea. The online workshop was attended by discipline experts from engineering contractors and subcontractors as well as the asset operator. The objectives of this SAFOP were to: Assess and minimize potential hazards to persons around or in the electrical installations; Provide a critical review of the electrical system design and equipment, assess any limitations and their effects on operability, safety and security of the system; Analyse […]
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 […]
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, […]
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.
