FSA 3 overpressure protection functions

jorgemartiresFunctional safety, Safety and reliability engineering

MAR Consulting was contracted to perform a functional safety assessment (FSA) stage 3 of overpressure protection functions in an offshore platform in the Norwegian Continental Shelf (NCS). The main objective of an FSA is to demonstrate compliance with IEC 61511 and 61508 functional safety standards, NOROG 070, and Petroleum Safety Authority (PSA) regulations through an independent assessment of the development process. Hence, the FSA process is a fundamental tool to ensure that the Safety Instrumented System (SIS) fulfills its requirements as an active barrier to reduce risk to acceptable levels. The FSA team shall have some degree of independence to […]

3rd party investigative study of ESD and SIS of offshore asset

jorgemartiresFunctional safety, Safety and reliability engineering

MAR Consulting performed an investigation on the safety systems of an offshore platform in the UK sector. Focus was on the Emergency Shutdown (ESD) and Anclilliary systems such as Safety Instrumented Systems (SIS). A list of findings and deviations of the current design and design documentation was presented to the client. The outcome will be used by the client to improve the safety of the design and meet requirements from UK regulators.

RAM analysis subsea tie-back

jorgemartiresReliability, availability and maintainability analysis, Safety and reliability engineering, Subsea engineering

MAR Consulting supported the development of a Reliability, Availability, and Maintainability (RAM) study for a new field subsea tie-back in the Norwegian Continental Shelf (NCS). The objective of the study was to provide the production efficiency (PE) estimates for the subsea field value chain in accordance with a revised base case and a high-level assessment for other three cases with different number of wells. In addition, a sensitivity analysis was performed for increased mobilization times due to no spare parts for the subsea production system (SPS), and subsea umbilical riser flowline (SURF).

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 […]

BOP FMECA update to API S53 5th Edition

jorgemartiresFailure mode analysis, Safety and reliability engineering, Subsea engineering

MAR Consulting AS updated a Failure Modes, Effect, Criticality and Diagnostics Analysis (FMECA / FMEDA) of the hydraulic control and safety systems of a major drilling contractor’s subsea drilling BOP. MAR Consulting had performed the previous original FMECA / FMEDA based on API S53 4th Edition and the US Code of Federal Regulations (CFR). The new rig contract requires compliance with API S53 5th Edition and therefore warranted the update. And it is outside the Gulf of Mexico where the US CFRs are not applicable. This work is part of the partnership to develop a BOP digital twin and failure […]

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 […]
