Present day energy production and consumption techniques are deeply rooted in methods which are unsustainable and therefore cannot be relied upon. Hence, there is an urgent call for an alternative clean and renewable energy source and as if now, offshore wind energy has proved as an ideal candidate for this scenario. An innovative installation method using a catamaran vessel was proposed by NTNU at SFI MOVE research centre and the purpose of this technique is to reduce the installation cost by cutting down the operation time taken for the installation.
This project intends to explore the possibilities to quantify the performance of the proposed catamaran installation vessel and if possible, provide suggestions to improve the performance of the whole installation process, on the grounds of relative motions at the mating point and the forces arising in the coupling elements while the mating process is underway. To help with the project scope, numerical modelling techniques are implemented to capture the dynamic behaviour of the spar-vessel system.
