1. Wind Fish Farm analysis: hele park kan aangepast worden aan de parameters (voor
meerjarig onderhoud).
2. Analyse: voordelen kunnen bekeken worden a.d.h.v. verschillende parameters
3. Year Scenario’s LCA: verschillende settings zijn mogelijk.
4. Zichtbaar maken van kosten die voortkomen uit de jaarscenario’s.
5. LCA data: Sale Prices worden gegenereerd.
6. Prijsstijgingen [met (on)zekerheids marges] kunnen gemoduleerd worden.
7. Technische en financiële data van het park kunnen geanalyseerd worden.
Een nieuwe factor is het ‘Synergy Percentage’. Met dit % wordt aangegeven in welke
mate de O&M kosten van de Wind Farm kunnen worden gereduceerd door minder
wachttijd t.l.v. de Wind Farm te laten komen (uit publicaties (2005-2012) blijkt dit in die
tijd rond de 30% te zijn) In huidige situaties is er bijvoorbeeld sprake van 40-50%
tijdverlies door; transitkosten, slechte afstemming, wachttijden, dus een
synergievoordeel van 10% zou al een hele verbetering zijn!
Resultaat: berekenen van revenuen, system cost-effectiveness, market value, return of
investment én grafieken waarin dit wordt weergegeven.

The accommodation is applied with as much as
possible double cabins to improve the comfort
when the accommodation is not completely filled.
Dimensioning of the accommodation is guided by
the SBM accommodation standard and the NMD
and ILO C133 code. At least it should comply with
SOLAS.

Wind Farm Analysis & Control
Aqua & Wind Farm Synergy:
Combines the O&M Cost (Wind + Mussel Farm) and subtracts the Mussel Profits in order to achieve
Wind Farm O&M Cost reduction.
Fixed Calculations:
Makes the variables fixed to their average value over the Life Cycle. Variables are
MCF,OEF,WPSP,MSP,CMA,WPI.
CMCI:
Corrective Maintenance Clearance Index

Price Elasticity (Wind Farm & Fish Farm)
Price Elasticity simulates the uncertainty of the sales price development over the Life Cycle, can
be adjusted individually for Wind Sales Price and Mussel Sales Price.
Select Multi Year Maintenance (Wind Farm & Fish Farm)
The MYM (Multi Year Maintenance) is the Maintenance Period in years, where in the last year a
Retrofit & Overhaul will be done. The Retrofit & Overhaul resets the SY (System Effectiveness) to
100%.
Synergy Factor
The factor at which within the O&M Offshore Wind budget, Mussel Farming activities can be done
by combining both the O&M Strategies.

Sales Prices over the Life Cycle
With Sales Price tab the Price Elasticity can be defined:
•
Trend Progression: Yr(A+1)=A+(a*sin(qx) + b*x + c)*(1-d(ASELECT-0,5))
•
D = Price Elasticity:
•
0 = Sales Price are predictable and have constant inflation.
•
10 = Sales Price are unpredictable and market crash can occur.

Failure Rate = 1/MTBF
Failure Rate / Installation = Failure Rate * Nr. Of Installations per System
Failure Rate / WT = Failure Rate / Installation * Nr of Installations per Cluster
Downtime Days / Year = Failure Rate / Installation * MTTR
Wind in Malfunction = (Downtime Days / Year) / 365
