Abstract
A new type of floating platform has been investigated. It is a small monocolumn semi-submersible floating platform with an internal air chamber that contributes to reduce platform vertical motions. It enables offshore wind tower to operate in deepwater, although a good performance can be also expected in harsh environmental conditions such as those seen in the North Sea. The power generated from the offshore wind system can supply electric power to run the oil and gas production equipment such as those in the process plant, platform facilities as well as those systems at the seabed. In this work, numerical simulations of platform motions are conducted with the aid of a previously developed formulation. Results for heave motions are shown considering scenarios with and without the air chamber effect and the mooring system. It has been verified that this new platform indeed experiences smaller motions which can increase the effectiveness of the wind power generation and improve the safety of operations.
