Ranked by Forbes Magazine as the world’s eleventh largest oil and gas company by revenue, Norwegian multinational company Statoil (now known as Equinor) turned to Shoreline for assistance with analyzing and developing their operations and maintenance marine logistic strategy as part of their UK East Coast R2 Project.
Simulations for many scenarios
The main scope of the study included simulations and subsequent investigation of alternative strategies for marine logistics and manning during the operational phase of the project. Statoil modelled several scenarios, including utilisation of various configurations of service operation vessels, crew transfer vessels and surface effect ships, with the Shoreline Operations & Maintenance Design module (previously called MAINTSYS™), the unique computer-based simulation software quick becoming the industry standard for sustainable energy forecasting.
Shoreline Operations & Maintenance Design performed simulations to examine variabilities in configurations for
- crew transfer vessels,
- service operation vessels,
- helicopters and
- living quarters.
The simulations were calibrated to include sensitivities concerning the number of technicians, vessels, shift patterns, HSE rules and more.
Reports from the study included estimations of technical availability impact, both time- and production-based, as well as investigations into limitations and step functions in the different alternative set-ups. The simulations were able to take into about variations in the number of turbines, for example, as well as other possibilities in configurations and maintenance schedules.
Accounting for complexity and time
Using Shoreline Operations & Maintenance Design, Statoil was able to account for the complexity (stochasticity, variability, time dependency and interdependence) of operating and maintaining an offshore wind park as well as increase their understanding of the system’s behavior over time.
