STOCHASTIC EVALUATION OF OFFSHORE CARBON FIBRE REINFORCED CONCRETE PLATFORMS ON ALUMINUM GIRDERS
ABSTRACT
A stochastic evaluation of the performance of Carbon Fibre Offshore Plastics (CFRP) offshore platform consideringsubmerged and partially submerged environmental conditions wasanalyzed usingSwedish code,Boverket (2004). A Probability-based analysis using First Order Reliability Method (FORM) was used to determine the safety index of the deck considering varied load ratios, effective depths of the deck, and ultimate strength of Fibre Reinforced Plastics (FRP) tendons.
The results generated from FORM indicates that theoretical framework for risk assessment based on the Joint Committee for Structural Safety JCSS (2003) showed that the maximum safety index of the CFRP deck was shown to be 3.49 which is higher than the limit set by the JCSS (2003) code. Hence the deck can adequately transmit the given loading conditions when designed in accordance with Boverket (2004). Also the resultsof the Finite Elementanalysis carried out on the deck showed that the von-Mises stress was within acceptable limits, implying that the resisting moment of the CFRP deck was adequate.
Hence, it is shown that the CFRP deck can be used in marine environment with increasing tidal loading as the CFRP wasalso able to resist failure due to compression. The flexural as well as shearing resistance are also within safety limits; and is about 500% greater than that of a steel reinforced concrete platform.However considering the serviceability limit state of deflection, the CFRP platforms did not show noticeable deformation in the geometry of the deck from the finite element analysis. The imposed load that can be sustained on a 150mm thick CFRP deck is 20kN/m2; while that of 200mm thick CFRP deck is 30kN/m2.
CHAPTER ONE
Introduction
1.1 General
Corrosion is a major problem on reinforced concrete structures especially in the case of macrocell formation, because it can cause local loss of the reinforcement cross-section in conjunction with subsequent cracking and spalling of concrete cover in the structure. With increasing deterioration,the serviceability will be impaired and the load bearing capacity decreases. The inspectionand maintenance strategies to detect such damages can be costly and economic planning is mandatory. In off-shore structures, structural components are built to be embedded in water as in the case of harbours, oil rig platforms just to mention a few. It is however essential that proper design to safely carry the imposed loadings be considered. Most importantly, design for the durability and resistance to: chloride effect, salty water, de-icing salt, freeze thaw etc. must be thoroughly considered (Humphrey, 2003).
Once corrosion gets started due to chloride ingress, an odic areas can be detected through potential mapping. Potential mapping provides two-dimensional information about a structure.This kind of information can be used for a spatial evaluation of corroding areas. It has to be considered that potential fields are influenced by several parameters such as concrete cover and resistivity, which always will have an effect on the spatial variability.

Is the topic “The Effects of Staff Welfare Scheme on Employee Productivity” recommended for Industrial Relations and Personnel Management (IRPM) Project?
Yes it is highly recommended — The Nigerian Local Government system has been fraught with a lot of problems since its inception in the colonial days. This is informed due to the various reforms that has been carried out by successive governments both at colonial and post impendence era. Despite these reform the Local Government has been characterized by low productivity corruption ineptitude and low morale to work. The Surulere Local Government Council is not an exception. Motivation of staff is a pivot to productivity of nay organization. Therefore, it becomes necessary to motivate workers to enable them work assiduously towards the goals and objectives of the organization. Ovation may not necessary be monetary compensation but also favourable condition of service which may not be quantified in terms …
