Most offshore wind farms are bottom-fixed at sites with less than 50 m of water depth. For deeper waters, floating platforms are economically viable and, for many countries that have steep continental shelves, this is the only option for developing offsh...

To increase the efficiency of gas-lift oil and gas production, it is necessary to improve the operation of compressor stations, namely, to increase the reliability of the gas-motor piston compressor units installed in them. It is found that one of the vu...

The revenue of a ship company, a terminal, a port and even the whole logistic chain largely depends on the performance of (un)loading operations inside port areas. However, they are conditioned by met-ocean agents that exert stresses on fixed structures,...
