In this phase of the operation the towmaster and superintendent coordinate the use of 10 winches and four tugs to align the two objects. Six bridge simulators were used together to simulate the different stations involved in the operation. This being a one of a kind operation, the simulator proved to be a tool that enabled the operators to get acquainted with the task at hand and to try out different strategies.


The final part of the simulation programme was executed with the topside in place. In this stage of the operation the two S-Class vessels are manoeuvred away from the spar using tugs.


The objectives of the workshop was to familiarise the Dockwise team with the operation, find best practices and assess the feasibility of each step of the operation. Lessons learned will be used to determine the preferred tug configurations, refine the operation and to prepare an optimum training package for the crews involved. At least two more training sessions are planned before the actual operation is carried out.


On the last day of the workshop, represent- atives of CB&I (front end engineering and design work), HHI (platform builder) and

Statoil (owner and operator) witnessed the simulations. Henning Selstad, Statoil’s platform marine operation manager of the Aasta Hansteen, emphasised that these kinds of


simulations are the way to prepare for such a complex task. He was very impressed by the capabilities of the simulator and the work done by Dockwise and MARIN so far.
