Fatigue Assessment of Longitudinal Stiffener End Connections for Ageing Tankers
Abstract: Abstract The world tanker fleet is ageing. In this situation it is essential to ensure that the transportation of oil and gas is carried out by quality vessels. This is possible with old tankers as long as their condition can be properly assessed. Since the 80’s relatively few new-buildings have been ordered and this has opened for operation of tankers up to 30 years of age. Ship and offshore structures …

Status of Surfactant-Polymer Flooding
Abstract: Abstract Surfactant-polymer (SP) flooding emerged from the principle that good sweep efficiency and displacement efficiency result in good oil recovery. Its research and development was shifted to alkaline-surfactant-polymer (ASP) because higher oil recovery can be achieved from the latter. Apparently, some research-development focus is coming back to SP, because ASP has problems in practical applications, e.g., scaling and emulsion. This paper provides the status of surfactant-polymer flooding technology. It covers …

Comparative Study on Fatigue Analysis Methods using Turret-moored FPSO Model
Abstract: Abstract Floating structures are prone to fatigue due to high cyclic loads mainly caused by waves and changing loading conditions. Therefore, fatigue is an important criterion during design. The fatigue life is dependent upon factors such as global and local design, workmanship during construction, maintenance, corrosion protection, and trade and load history. Different approaches are applied to the fatigue strength assessment. Longitudinal stiffener end connections are also important structural elements …

A Conceptual Framework for Safeguarding Endangered Animals Through Wireless Body Sensor Networks
Abstract: Since life began on Earth, incalculable creatures have come back and gone, rendered extinct by naturally dynamical physical and biological conditions. Though extinctions occur naturally, scientific proof strongly indicates that this rate of extinction is far on top of the natural or background rate of the past. The main reason driving this higher rate of loss is habitat loss. Over-exploitation of wildlife for profit-making purposes, the rough guide of destructive …

Enhancement of Bioavailability of Clopidogrel Using Different Solubility Enhancement Techniques
Abstract: Bioavailability is the key determinant of a drug for its therapeutic effectiveness, which in turn depends upon the solubility of that drug in gastro intestinal fluid. Clopidogrel is a BCS class II drug. Drugs of this category have low solubility and high permeability, so their bioavailability is less. This can be overcome by doing pharmaceutic modifications on it. In the present study, three different modifications, namely, complexation, solvent deposition and …
