A successful offshore construction operation such as platform installation, decommissioning and subsea pipeline construction relies on good engineering and planning before the operation. Good planning is helped by having the ability to use the first available weather window to carry out the operation at the field offshore. Therefore, the ability to forecast the governing engineering criteria during the operation becomes an essential component. This paper presents the developed methodology to forecast events and a summary of the status of the development, including its limitations and applications. It is focused in three areas: forecast and monitor the dynamic motion characteristics of the operation, pile stick-up motion for jacket installation, and prediction of sag bend bending moment during subsea pipeline construction. It is concluded by presenting the proposed future development and advantages.
