Reduction of Harmful Emissions from IC Engines using Hybrid Aqua Charcoal Replacing both Silencer and Catalytic Converter
Abstract: The application of IC Engines is ever raising as a power source in industries, on road and off road vehicles, marine vehicles etc. Harmful gases emitted from IC Engines are causing global warming and various ailments to human beings. There is a need to take measures to reduce emissions like carbon monoxide, unburned hydrocarbons, NOx etc., from IC Engines to comply with stringent environmental pollution regulations imposed upon. In this …

Assessing Underwater Noise Levels during Various Port Activities at the Visakhapatnam Channel
Abstract: Transport infrastructure is one of the most important factors for country’s progress or economic growth. Ports serve as important transportation hubs that facilitate goods movement. Visakhapatnam Port is the second largest port by volume of cargo handled located in the east coast of India. Under the modernization program the port is capable for handling vessels upto 14.5 mby maintenance dredging and some jettiesextension with piling activity. The major activities of …

Advantages of Having DP Class 3 for Well Stimulation Vessels (WSVS) Compared to Existing DP Class 2 Possibility and Analysis of Failures of DP2 Capable WSVS
Abstract: An intervention performed on an oil or gas well to increase production by improving the flow of hydrocarbons from the reservoir into the well bore is well stimulation. The improvements in completion treatmenttechniques like Well stimulation have impacted recovery rates of hydrocarbons such that there is a possibility to pull tens of millions of barrels of oil out of a well, all whilekeeping that well online for 20 years.To perform …

A Study on Harbour Siltation and Dredging in Vizhinjam Port Using a Numerical Modeling Tool
Abstract: This paper tries to study the harbour siltation in the proposed Vizhinjam port using a numerical modeling tool (Delft3D). Secondary data collection has been carried out from various sources for obtaining Oceanographic and bathymetric data and used in this study. The simulation results were calibrated using the measured current and tide. From the wave coupled simulation results it is found that waves have very less influence in the siltation of …

Study on the Wave Diffraction Patterns in the Kakinada Bay
Abstract: Kakinada is one of the major upcoming portsof India and holds great importance for shipping activities. This region is said to be low-lying area and highly susceptible to erosion. To protect the port from action of waves, tides and strong currents, breakwater was constructed at the entrance of the channel. Current study makes an attempt to understand how wave energy gets reduced and wave diffraction occurs due to presence of …
