The operation of offshore floating units is greatly affected by weather-influenced motions. StormGeo has combined state-of-the-art technologies from meteorology and hydrodynamics to forecast these motions and provide decision support, enabling you to increase uptime and safeguard operations.
Our Response Forecasting services provide decision support for a safe passage for personnel between the flotel and host installation.
Our systems give you the necessary information to optimize connectivity while still adhering to the highest safety standards.
Our system allows users to plan and schedule the disconnect according to procedures.
StormGeo has an excellent feedback and rapport with its customers. StormGeo is willing to look at and revise prediction models based on actual observed data.Gareth Turner
I would recommend StormGeo to other companies looking for a weather service provider because of their commitment to deliver reliable forecasts on time, together with their willingness to adjust their products to match your needs.Esben Jettestad

StormGeo has state-of-the-art technologies to forecast weather-influenced motions and provide decision support.
Undesirable movements in floating offshore installations can be the origin of potentially dangerous situations and expensive shutdowns of operations.
StormGeo’s Response Forecasting is designed to predict the movements of the rig and drilling deck by combining accurate weather information with detailed knowledge of the predicted response of each floating unit. This increases the accuracy of operational planning and logistics, reducing risk and drilling costs.
Advanced hydrodynamic models forecast motions of offshore floating units to improve performance and ensure cost-effective operations.
Availability Analyses reduce the uncertainty of downtimes caused by rig motion, resulting from weather (wind and waves) interaction with the drilling rig. StormGeo uses hydrodynamic analysis together with high-quality hindcast weather data to calculate the probability of a defined rig motion occurring or the likelihood of breaching a certain motion limit criteria.
The results are used to estimate the operational availability of a specific drilling rig in a specific location when considering rig motion limitations, e.g. heave amplitude limitations due to heave compensating system.
Response Forecasting minimizes the need for using over-conservative limits based on wave height only. It allows for planning around a more accurate prediction of when heave compensation systems will no longer cope with weather conditions.
The basis of the technology is to combine the advanced hydrodynamic models of the vessel with weather forecasts. The result is accurate forecasts of rig motions for the planning of drilling and helideck operations.
The system uses StormGeo’s high-quality weather information, in combination with advanced rig dynamics modelling (from Deep Sea Mooring), to simulate and forecast the relative movements of the flotel, gangway and attached platform. It simulates multiple headings in a predefined sector, allowing for the easy planning of optimal positioning of the flotel, which ensures maximum availability.
In situations where a disconnect cannot be avoided, the system allows users to plan and schedule to disconnect according to procedures.
