A Review Of Survivability And Remedial Actions Of Tidal Current Turbines
A Review Of Survivability And Remedial Actions Of Tidal Current Turbines
Faculty of Engineering University of Malaya
Tidal current energy is one of the most predictable ocean renewable energies. Survivability of the device used to harness tidal power and its remedial actions are critical to ensure a successful power generation. Marine environment is harsh with the continuous attacks of waves, current saline water and microorganism. Support structures are discussed including gravity base, monopile, tripod/piled jacket and floating structure. Extreme weather increases the wave height and current speed to produce high loading at the turbine. Support structure is designed to sustain the loadings from the extreme weather. Protective seabed unit should be included to prevent the seabed scouring. …
Engineering And Sustainability Performance Of Self-Compacting Palm Oil Mill Incinerated Waste Concrete
Faculty of Engineering University of Malaya
The different stages in the processing of palm oil generate various types of waste by-products, which have to be disposed of appropriately for a cleaner environment and to reduce pollution. In this study, palm oil clinker (POC), one of the by-products of the palm oil mill, was utilized in the production of self-compacting concrete (SCC). SCC has diverse types of structural application due to its own enhanced self-consolidating behaviour. The proportioning of the mixes was based on particle packing, which integrates both aggregate packing and void volume for a mix of aggregates. Combinations of POC and natural aggregate were studied …
Avoid Sulfuric Acid Corrosion In Metallic Stacks, João F. Gomes
Avoid Sulfuric Acid Corrosion In Metallic Stacks, João F. Gomes
João F Gomes
Acidic gaseous effluents frequently cause corrosion on metallic stacks. This paper presents a method for prevision of probability of corrosion occurrence caused by gaseous effluents containing sulphur oxides which is based on the sulphur trioxide and moisture content measured in stack
