QA/QC RAM analysis turret and mooring FPSO

MAR Consulting provided quality assurance (QA) and quality control (QC) of a Reliability, Availability and Maintainability (RAM) analysis of a turret and mooring of a Floating Production, Storage and Offloading (FPSO) vessel. The system consisted of a single point mooring and submerged turret production (STP), based on technology developed by the client. The RAM analysis documented the methodology and results in terms of production efficiency for the turret and mooring system.

RAM analysis subsea tie-back

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

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 […]

QA of RAM analysis for FPSO stationed in Norway

MAR Consulting AS had assisted on producing a reliability, availability, and maintainability (RAM) analysis of a floating production storage and offloading (FPSO) unit to be stationed in the Norwegian continental shelf (see the previous article here). The initial model in the front-end engineering (FEED) phase had the objective of estimating the production efficiency of the current configuration, providing insight on bad actors and basis for modifications to improve the production efficiency. Since then, the model was further developed to include further details during the design and detailed engineering phase. The objective is to provide a more accurate estimate of the […]

FPSO availability effect on 3rd party liquid evacuation

MAR Consulting performed an availability study of a floating, production, storage and offloading (FPSO), which will be operating in the Eastern Mediterranean Sea. The development plan envisages the use of an FPSO with full offshore processing capabilities of the reservoir fluids. Conditioned gas will be exported to shore and tie-in to the country’s gas distribution grid. The associated light¬†oil will be exported offshore by tandem offloading to a shuttle tank. The FPSO storage tanks were being considered to evacuate a third-party operator light oil from a nearby field, in addition to the light oil from the FPSO’s own operating field. […]
