Abstract:
A computer model that calculates the transport and installation costsof a wind farm has been composed and implemented in the OWECOP II model
of ECN. The latter quantifies all costs of implementation of a wind
farm, at a determined location on the Dutch Exclusive Economical Zone.
Transport and installation are a part of it. The computer model is an
ExcelTM workbook that includes an input part, a database
part and a calculation part.
Transport and installation costs have been derived based on available
offshore techniques and structured according to possible wind turbine
assembly procedures. Besides the cost of offshore equipment, also an
estimation of delays due to bad weather and the use of several vessels
simultaneously have been included. Other costs included are: Scour protection
costs, costs of soil research, costs of electric cable installation
and costs of removal of wind turbine / wind turbine components after
their operational lifetime.
The calculation of costs for transport and installation of offshore
wind turbines as implemented in the OWECOP model, could be detailed
by a deeper analysis of workable conditions (probability of work) and
implementation of wind turbine sizes and dimensions related to the transport
and installation vessels.
