Renewable sources at offshore petroleum and gas production platforms

Mauricio F. Oliveira Marco Antônio Saidel Alan Romulo Silva Queiroz Epitacio N. Filho

The petroleum and chemical industries are facing pressure to become more energy efficient and sustainable. The use of green energy is a feasible option to address that issue. This paper discusses the application of various source technologies available to offshore petroleum and gas production platforms. The pros and cons of each source is considered, as applied to critical systems, including safety systems. A hybrid system using photovoltaic cells and wind generation, installed on an offshore platform in Brazil is reviewed.

Maintenance Strategy for Electrical Equipment Based on Integrated Operations

IEEE Transactions on Industry Applications (2016)

Alan Romulo Silva Queiroz Eduardo Cesar Senger Luciene Coelho Lopez Queiroz Estellito Rangel Victor Silva de Paula

This paper presents a methodology to define a maintenance strategy for electrical equipment, including electric motors. This methodology is based on reliability-centered maintenance, and aims to ensure that the maintenance strategy results in maximum availability and efficiency of equipment and systems. The methodology is also compatible with the philosophy of integrated operations recently developed by the Norwegian petroleum industry to optimize the production from their mature oil fields. The first step is focused on the determination of the equipment criticality value. The paper proposes a methodology based on the Mudge method. Reliability criteria are adopted according to the criticality value. The maintenance intervals are determined considering the reliability criterion and the failure rate of each part of a motor. After determining criticality, the maintenance strategy and tasks are analyzed and determined based on failure modes and failure rates. To support this analysis, a procedure based on failure mode and effect analysis theory is used.

Reducing Arc Flash Incident Energy Level in an Offshore Gas Production Unit Using Intelligent Electronic Devices—A Case Study

IEEE Transactions on Industry Applications (2014)

Alan Romulo Silva Queiroz Eduardo Cesar Senger Mauricio F. Oliveira Lauri Kumpulainen Roberto Chavez

This paper evaluates the protection system of an offshore gas production unit and proposes utilization of devices dedicated to identify the arc flash incidents inside the panels. A quantitative analysis has been performed by comparing the incident energy levels of the original design with the levels provided by the new design. The new design includes numerical relays equipped with dual sensing of arc flash: optical detection of the light and high-speed overcurrent detection. The analysis indicates that a drastic reduction of incident energy can be achieved. The reduction is based on very fast detection and elimination of the arc, lowering the arcing time.

The Importance of Inspections on Electrical Installations in Hazardous Locations

IEEE Transactions on Industry Applications (2015)

Estellito Rangel Alan Romulo Silva Queiroz Mauricio F. Oliveira

Electrical installations in hazardous locations (classified areas) need careful attention because nonconformities can bring considerable risks not only to the site but also for other industries and residential areas nearby. To assure safe operation of an industrial facility, it is not only necessary for all electrical and electronic equipment to be used in hazardous locations to be correctly specified and purchased (known as "Ex equipment") but also properly installed and maintained. The discussion in this paper is largely based upon International Electrotechnical Commission standards; however, conceptually, the same philosophy is also found in American standards and installations as well.

Renewable sources at pre-salt platforms

Mauricio F. Oliveira Marco Antônio Saidel Alan Romulo Silva Queiroz Luiz G. O. Goncalves

The recent discoveries of Brazilian pre-salt oil fields are facing a new scenario in the global oil and gas industry. The latest offshore exploratory and production opportunity requires complex production projects and high technology equipment. Brazilian development oil production master plan determines construction and installation of more than forty offshore platforms. In this scenario, renewable sources emerge as an interesting application in order to mitigate environmental impacts usually caused by oil and gas production activities. Diversification of energy matrix applied at industrial plants by installation of renewable sources can make oil and gas business more sustainable and cleaner. The purpose of this work is to present a qualification and quantification study about renewable energy flows at offshore petroleum and gas production platforms designed for Brazilian Pre-salt oil and natural gas fields. A single platform evaluation is performed by simulating the installation of converters.
