Electrical SAFOP E-HAZOP LNG project

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

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, […]

Cyber-security risk assessment of offshore assets

MAR Consulting facilitated a cyber-security risk assessment for an operator of offshore assets in the Norwegian Continental Shelf (NCS). The assets shall comply with the strict Norwegian regulatory requirements. Petroleum Safety Authority (PSA) in Norway runs periodical audits to ascertain the level of IT security (among others) in the operating assets in the NCS. This work is part of an extended partnership with the operator to identify potential cyber-security vulnerabilities in their portfolio. Other assessments part of this work are: Cyber-security assessment of FPSO IT/OT systems · MAR Consulting; Cyber-security risk assessment of FPSO · MAR Consulting; Cybersecurity hazard identification […]

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 […]

Cyber-security risk assessment of FPSO

MAR Consulting facilitated a cyber-security risk assessment of the systems required to operate a floating, production, storage and offloading (FPSO) vessel. The FPSO is currently operating in the Norwegian Continental Shelf (NCS). It is required to adhere to the strict regulatory requirements in the country. Petroleum Safety Authority (PSA) in Norway runs periodical audits to ascertain the level of IT security (among others) in the operating assets in the NCS. The main objective was to draw on the collective experience and lessons learned to identify potential cyber-security hazards. Other objectives were to analyze and evaluate identified cyber-security risks and propose ways to prevent […]

Cyber-security assessment of SAS/ESD system

MAR Consulting performed a cyber-security assessment of a recent upgraded safety and automation system (SAS) on a platform in the North Sea. The main focus was on the emergency shutdown system (ESD) and supporting data network infrastructure. Cyber-security assessments are now required by functional safety standard IEC 61511:2016 Ed. 2. The main objective of the study was to identify cyber-security threats, breaches, and vulnerabilities in the system, with the potential to cause damage and downtime to the platform. Confidentiality consequences were not considered in this study. Each identified scenario was described in terms of consequences, existing barriers and risk ranked […]

Nuclear industry risk identification – contract extension

MAR Consulting AS received a contract extension to perform hazard identification (HAZID) and operability analysis with regards to worker safety in a major new build in Lund, Sweden. The new build will be a European nuclear research facility. Further responsibilities include oxygen deficient hazard (ODH) analysis and defining processes, rules, guidelines, and procedures for risk identification, analysis, evaluation and treatment within the facility during design, manufacturing and installation phases. https://www.marconsulting.no/2017/11/27/new-contract-in-nuclear-industry/

EHAZOP of power plant concept

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

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 […]
