Fatigue Assessment of Flare Foundations on FPSO Structure
Abstract: This paper addresses the fatigue analysis results of the new-built FPSO’s flare tower foundations and associated the hull which is supporting the four cylindrical legs of the flare. Flare foundation is checked for fatigue resistance both in “towing” and “on site” conditions. The fatigue design of the flare supporting structure is to take into account the inertia loads due to wave motions in towing and on site, but also the …

Issues in Updating Technology Education for Skills Sustainability in Nigeria
Abstract: The triangular productivity factors of production which include land, labor, and capital are inevitable in leading the development of the industrials, agricultural, tertiary health care, increase employment rate, and national income. The growth rate of the national economy depends solely on the provision of sound academic foundation which create the needed awareness. Performance measure in both public and private sector is adjudged based on production rate, the income and wages, …

Nonlinear Three Dimensional Dynamic Analysis of Titanium Drilling Riser
Abstract: Titanium alloys are selected for a high-pressure drilling riser’s application due to its high specific strength, corrosion resistance, and favorable elastic properties. The qualification of this titanium alloy requires assessing its resistance to hydrogen embrittlement and stress corrosion cracking due to seawater with/without cathodic protection, evaluating its dynamic response under long crested random sea. The response analysis is based on a simulation technique which duly considers the various nonlinear effects …

Strengthening Infrastructure Projects Sustainability through Modified Quality Conformance Alternative
Abstract: Across the length and breadth of the society, infrastructure project is considered as major in the sustainability of the living standard of the people within a concentrated area covered by the government goodwill, yet these lofty objectives frequently “rock” few months or year after inauguration of such project. Government most often are good in initiating viable projects, but the machinery to monitor the usage and functionality of these projects usually …

Fatigue Design of Anode Supports on Offshore Structures
Abstract: This paper addresses the fatigue analyses results for external and internal anodes’ attachments on the offshore structures using finite element analysis, where a simplified empirical formula is also recommended. For anodes that may become subject to significant forces during installation and operation, the design of anode fastening devices shall be addressed in early design stage. Doubler and/or gusset plates may be required for large anodes. The anode steel should be …
