Ocean Response Forecasting

Use cutting-edge meteorology and hydrodynamics to predict wave risks ahead of time. This helps improve operational efficiency and keeps people safe.

Key benefits

Safety of crew

Response forecasting provides decision support to ensure a safe window of operations for your personnel, between the flotel and host installation.

Reduce downtime

Our solutions give you the necessary information to optimize connectivity while adhering to the highest safety standards.

Safeguard operations

Our solutions allow users to plan and schedule the disconnect according to procedures.

Details and specifications:

We forecast weather-influenced motions and provide decision support.

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. 

Increase the accuracy of your operational planning and logistics, reducing risk, shutdowns, and drilling costs.

Spectral Wave Analysis

  • This service provides non-vessel response service for 2D ocean conditions.
  • It calculates the wave height, direction and period based on swell systems and winds.
  • The service can be accessed through an API or a portal, where the results are displayed as spectra graphs.
  • Spectra show the energy distribution of the waves in different frequencies and directions.

Hydrodynamic analysis and modeling forecast

  • Advanced hydrodynamic models forecast motions of offshore floating units to improve performance and ensure cost-effective operations.
  • Rig and drilling deck forecasts predict heave, sway, surge, pitch and roll motion tailored to each floating structure.
  • Helideck motion forecasts predict the helideck’s heave, pitch and roll movements, then give the appropriate green, red or yellow light to support planning a more optimal helicopter schedule.
  • Forecasted modeling optimizes positioning of a flotel, by forecasting the relative movement of the flotel and the gangway stroke to the attached platform. It simulates multiple headings in a predefined sector, ensuring maximum availability of the gangway connection.
  • Improved HSE performance. We are using SIMO or MIMOSA models, which receive information from ECMWF wave models and allow you to make knowledge-based decisions to save costs.

Availability analyses

  • Availability analyses reduce the uncertainty of downtimes caused by rig motion, resulting from weather (wind and waves) interaction with the drilling rig.
  • We use 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.

Forecast of critical responses

  • 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.

Flotel and gangway continuous decision support

  • Our high-quality weather insight is combined with advanced rig dynamics modeling (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.

Dedicated meteoroligist 24/7, 365

StormGeo's meteorologists are always available—via telephone, email or even on-site by assignment. For on-site assignments, a StormGeo forecaster with the required offshore certificates will follow your operations over an extended period of time.

By working on board your vessel or installation, they can provide expert, immediate decision support on operational windows to increase efficiency wherever necessary.
