Conceptual analysis on Guyed Monopiles for Offshore Wind Turbine Generators in Deep Water

The demand for offshore wind energy has never been higher, yet the number of ideal areas for wind farm installations is decreasing. As a result, larger wind turbines are being placed in deeper waters, which poses opportunities for floating foundations. However, due to the industry's inability to scale up the production of relatively expensive...

Reducing payload motion during offshore operations

Offshore lifting operations must have reduced payload motion to increase safety and reduce operating time. When payload is retrieved from the splash zone to the deck, besides the crane block, no additional control can be applied on the underactuated system. Existing studies either assume more control over the payload or develop a control system...

Structural integrity assessment of self-elevating units with fatigue and corrosion damage based on actual load history

Seafox owns and operates a fleet of 12 Jack-ups. The design life of these Jack-ups is typically around 30 years. However, some have remained operational after exceeding their design life. It is therefore critical to gain an understanding how long and under what conditions these jacks-ups are still able to operate safely. There are two main...
