Abstract
COSMO – a Computer tool for Optimisation and Simulation of Marine Operations has been developed over several years by SINTEF in cooperation with Equinor. It aims at finding and simulating optimal schedules for installation of offshore wind farms. The tool’s origin was an idea formed by SINTEF Ocean (then MARINTEK) in the EU financed project Leanwind
(2013-2017). The tool has developed through a pre-project in 2016 designing a mock-up, a prototype development project in 2017, and resulted in a fully integrated web-based version that is currently being further developed according to industry needs through projects at SINTEF such as FME NorthWind and Horizon Europe project INF4INiTY. The underlying solution algorithm of COSMO is a simulation engine that simulates installation schedules based on a schedule generation procedure that proposes candidate schedules. The algorithm combines optimisation and simulation in a bi objective framework that optimises based on time and cost of an installation schedule. Hence, the user provides input based on components that are to be installed at a wind farm, installation vessels and their capacities and COSMO generates several installation schedules that are found on the approximation to the Pareto front. Then the user can compare schedules and view risk profiles based on the simulated weather profiles of the schedules. Although the current user interface of COSMO is based on installation of offshore wind farms, the procedure implemented is generic and the core of COSMO is optimisation and simulation of marine operations. In this presentation we will guide you through the development process of such a tool and point at lessons learnt in the process of making.
