VERticale: Offshore Wind Installation Vessel uyk Engineering Rotterdam presented its new foundation

Vinstallation vessel (FIV), VERticale.

“VERticale is developed for an optimized deck layout,” said

Kuno van den Berg, Department Manager Operational Engineer- ing, Vuyk Engineering Rotterdam. “The location of the offshore crane, motion compensated gripper and position of monopiles are all ? ne tuned for ef? ciency. VERticale aims for a minimum num- ber of offshore handling operations. Not only loading and sea fastening is done in a controlled port environment, also upend- ing. This results in less motion sensitive operations offshore and lower risk and increased weather window for the actual monopile installation. Thus, operating expenses (OPEX) are reduced”.

The transport layout with vertical positioned monopiles re- sults in a relatively compact vessel of 218 x 70 meters. For monopile or jacket installation, VERticale is out? tted with a 5,000-ton offshore crane.

“The challenge was to ? nd a balance between vessel ca- pabilities for installing future wind turbine generator foun- dations, with a clear focus on capital expenditure (CAPEX) minimization combined with the same or lower OPEX,” said

Nicky Mayenburg, Technical Sales Manager. “Other solutions and concepts have been studied, but most result in larger ves- sel dimensions and more complex handling operations when the vessel is offshore. The VERticale setup results in a bal- anced solution for installing future wind farms”. 42 Maritime Reporter & Engineering News • January 2023
