Monitoring of flexible oil lines using FBG sensors

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2008)

S. R. K. Morikawa Claudio Camerini Daniel Rodrigues Pipa João M. C. Santos Gustavo P. Pires

Thorough the last two decades, oil and gas reservoirs discovered and developed in deep and ultra deep waters have continuously posed challenges to petroleum exploration and production activities in offshore basins. Maintaining optimum flow rates of oil and gas from subsea wellheads to surface processing facilities demands new technological solutions for petroleum companies operating in such frontiers. Integrity assurance of structures, equipment, and flow lines plays a major role in maximizing offshore production systems availability while at the same time keeping safety, operational, and environmental risks at minimum levels. In this scenario, implementation of permanent health monitoring solutions must take into account the environment of oil and gas production facilities, where installations in hazardous classified areas require explosion and fire-proof instrumentation. In this context, optical fiber sensors offer an attractive alternative to electrical sensing technologies, which, until now, have been the primary choice by maintenance personnel at offshore production units.

A Malleable Model Development for Critical Systems Supervision Integration

Luciano A. C. Lisboa Thamiles Rodrigues de Melo Ikaro G. S. A. Campos Matheus B. Aragão Alexandre S. Ribeiro

The critical systems, which the failure and malfunction may result in human, environment and financial severe damages, are essential components in various sectors and particularly in energy domains. Although unwished, integration error problems in supervision of critical systems occurs, incurring significant expenses because of operator’s subjective analysis and on hardware topology failures. In this work, a malleable model design approach is proposed to formulate and solve the integration error problem in the critical systems supervision in terms of reliability. A real Hybrid Power Plant (HPP) case is considered as a requirement for a study case with simulated data. A method framework with informal approach (C4 diagram) and formal approach (Hierarchical Coloured Petri Nets) in radial spectrum is applied to the HPP supervision design. Using formal methods, a formulation and solution to this problem through structured, scalable and compact mathematical representations are possible. This malleable model intends to guarantee functional correctness and then reliability of the plant supervision system based on system software architecture. Outcomes suggest corroboration that the malleable model is appropriate for energy domain, and can be used for other types of critical systems, bringing all the benefits of this methodology to the context in which it will be applied.

Non-Intrusive Fluid Flow Measurement by FBG Sensing of Flow-Induced Vibrations

Paula M. P. Gouvêa Khrissy Aracélly Reis Medeiros Alexandre S. Ribeiro Carlos Roberto Hall Barbosa José Roberto Moraes d’Almeida

We developed a non-intrusive flow sensor for pipe flow based on FBG and FIV. The standard deviation of the strain time series signal obtained by the FBG and the flow rate present a quadratic dependence.

The Expression of A-Type Lamins as a Regulator of Mechanics of the Nucleus and Cell Mechanotransduction

ASME 2008 Summer Bioengineering Conference, Parts A and B (2009)

Alexandre S. Ribeiro Nicholas S. Wren Jonathan W. Jarvik Kris Noel Dahl

Mechanotransduction of extracellular stimuli into the chromatin located in the cell nucleus and overall cell mechanics may require the physical support of structures of A-type lamins. Several cellular pathologic phenotypes and phases of stem cell differentiation involve regulation and reorganization of A-type lamins. Here is presented a study of changes in cell mechanics associated to the reorganization of nuclear structures consequent to knockdown of A-type lamins. Transient dysmophism of the cell nucleus is observed during knockdown of A-type lamins, which seems to be driven by inner cellular forces resultant of cytoskeletal and chromatin structural reorganization.

Fatigue Assessment and Monitoring of a Dented Pipeline Specimen

Volume 1: Codes and Standards (2019)

J. L. F. Freire V. E. L. Paiva G. L. G. Gonzáles Robson D. Vieira José Eduardo Maneschy

Abstract The present paper reports initial results from an investigation program launched with the objective of presenting combinations of analytical, experimental and numerical methods to predict and monitor fatigue initiation and fatigue damage progression in equipment such as pressure vessels, tanks, piping and pipelines with dents or complex shaped anomalies. The monitoring of fatigue initiation and propagation in the actual specimens used nondestructive infrared inspection techniques. Thermoelasticity stress analysis (TSA), three-dimensional digital image correlation (3D-DIC) and fiber optic Bragg strain gages (FBSG) were used to determine strains at fatigue hot spots locations. Strain fields determined from the experimental measurements and from finite element analysis (FEA) were combined with the fatigue Coffin-Manson strain-life equation and the Miner’s fatigue damage rule to predict fatigue life (Nc). Results from one tested 3 m long tubular specimen containing a complex shaped dent are reported and fully analyzed.

An Automation System Simulator for Integration of a Hybrid Power Plant: A Real-Unit Case Study

Ikaro G. S. A. Campos Matheus B. Aragão Leonardo C. Guerra Luciano A. C. Lisboa Giovanni Malisano

This paper describes the implementation of an automation system simulator using low-cost prototyping for testing the communication interfaces and data flow in the automation architecture of a hybrid power plant (HPP) real-unit. The CHESF PV-WF-BESS HPP in study is composed by the insertion of a Photovoltaic System (PV) and a Battery Energy Storage System (BESS) for the hybridization of a Wind Farm (WF) at Casa Nova - Bahia, Brazil. The automation system of this HPP follows a hierarchy architecture divided into five layers: (1) Local controllers; (2) Remote Terminal Unit (RTU); (3) Supervisory Control and Data Acquisition System (SCADA); (4) Plant Information Management System (PIMS); and (5) Intelligence software for power dispatch orders. The simulator structure is obtained using two Programmable Logic Controllers (PLCs) Siemens SIMATIC S7 1200, simulating the local asset controllers and RTU in Layers 1 and 2; and two Personal Computers (PCs), representing the roles of SCADA system in Elipse Power, PIMS in Elipse Plant Manager and Application Programming Interface (API) coded in Python, in Layers 3, 4 and 5, respectively. From this system simulator, the integration between the automation layers can be validated, in order to assist in commissioning and implantation stages of the CHESF PV-WF-BESS HPP.
