TQP new part of multiphase meter (MPM)

jorgemartiresElectrical engineering, Risk treatment

MAR Consulting developed a Technology Qualification Plan (TQP), according to DNV-RP-A203, for a new part of a multiphase meter (MPM). The plan shows that performance criteria and all risks identified during a Failure Mode, Effects, and Criticality Analysis (FMECA) workshop have been addressed by choosing and applying suitable qualification methods. The outcome of related activities shows no degradation of the overall MPM metering performance but a successful measurement decoupling from downstream piping configurations, as intended.

Availability of LV concept for wind power substation

jorgemartiresElectrical engineering, Reliability, availability and maintainability analysis

MAR Consulting supported the development of an availability study of a new concept for low voltage (LV) power supply to auxiliary systems in offshore wind substations. The concept proposed includes less redundancy. Therefore, it is essential to understand how it may impact the availability of the LV wind power substation. The substation’s main objective is to transmit offshore wind power to the onshore grid. For this purpose, auxiliary systems are essential to maintain the substation operationally capable. Failure of power to auxiliary systems such as cooling pumps, etc results in the inability to transmit power to shore. It was concluded […]

System design review wind power offshore platform

jorgemartiresElectrical engineering, Facilitation, System design review

MAR Consulting facilitated a wind power system design review for an offshore substation platform. The platform receives power generated from offshore wind turbines (North Sea) and transmits the power to shore. This is a follow-up to the internal design review performed with the engineering company. In this review, the operator also participated – both the project team and operational organization. The main objective of the system design review of the wind power platform was to ensure that the system design is in accordance with the Authorities’ rules & regulations and the Client’s requirements. We focused on process safety, operation, maintenance, […]

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 […]
