Mini-HAZOP and LOPA – open drain offshore wind power substation

jorgemartiresHazard identification, Risk analysis

MAR Consulting facilitated a mini-HAZOP (hazard and operability) and a LOPA (layers of protection) analysis of an open drain system in an offshore wind substation platform. Since the platform is normally unmanned and due to environmental conditions in the region (South Korea), the Operator prefers to discharge the open drain inventory to sea. The discharge shall be processed to avoid potential contaminants (such as transformer oils, foam from active fire protection, etc) to sea. Discharging to sea is an alternative to collecting the open drain in a sump tank and potentially requiring extra de-bunkering visits. The objective of the HAZOP […]

HAZID topside offshore wind substations in East Coast USA

jorgemartiresFacilitation, Hazard identification

Introduction MAR Consulting facilitated a hazard identification (HAZID) workshop of topsides of three (3) offshore wind substations (OSS) platforms. The methodology was based on the guidewords from DNV-ST-0145 with addition of other relevant topics such as work environment related hazards. The HAZID of offshore wind substations covered the topside during the operational phase only. The substructure including the application of the structure as a system for supporting the topside and for transfer to / from a crew transfer vessel (CTV) were not assessed in this HAZID. Participation from the different engineering contractors, as well as the operator and a 3rd […]

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 […]

MAR Consulting facilitated and documented a 2-day computer and control system HAZOP (CHAZOP) and a what-if analysis for an electrical power plant in Aruba. Major upgrades to the control system (HMI, PLCs, and network) triggered the analysis, with the objectives to: ▪ Evaluate the control system design modifications with regards to safety and operability;▪ Eliminate or reduce the likelihood of accidents and incidents due to the control system design modifications;▪ Identify and recommend design improvements. A what-if/ CHAZOP is a systematic review of the design and operation of a control system. MAR Consulting conducted the study as a multidisciplinary workshop […]
