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

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 […]

CHAZOP of control system on electrical power plant

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 […]
