Structural optimization of offshore wind turbine structures has become an important issue in the past years due to the noticeable developments in offshore wind industry. However, considering the offshore wind turbines’ size and environment, this task is outstandingly difficult. To overcome this barrier, in this paper, a metaheuristic algorithm called Enhanced Colliding Bodies Optimization...

This paper examines liquidity premium focusing on the difference between offshore and onshore hedge funds. Due to tax provisions and regulatory concerns, offshore and onshore hedge funds have different legal structures, which lead to differences in share restrictions such as a lockup provision. We find that offshore investors collect higher illiquidity premium when their investment has the same...

In this study, an Internet Protocol(IP)-based integrated network management system(INMS) that can be managed on site and remotely was designed. To derive the requirements for an offshore plant INMS, the status of the offshore plant-related industries was analyzed, and the structure and functions of the system were designed by referring to the actual ship-owner specifications and shipbuilding ya...

Marine structures are one of the most important and susceptible facilities in Iran due to corrosion. The two methods of Cathodic Protection, namely, the cathodic protection with sacrificial anodes and cathodic protection using impressed current, are widely used for corrosion protection. According to the former, sacrificial anodes are installed at several points in the structure. Position of the...

Structure-borne noise is an important aspect of offshore platform sound field. It can be generated either directly by vibrating machineries induced mechanical force, indirectly by the excitation of structure or excitation by incident airborne noise. Therefore, limiting of the transmission of vibration energy throughout the offshore platform is the key to control the structureborne noise. This i...
