Offshore Decision Support Tool
The Offshore Decision Support Tool (ODST) by 4Subsea combines live vessel data with high-resolution weather forecasts and advanced analytics to optimize offshore planning and execution. Through a user-friendly digital interface, ODST reflects real offshore processes and provides critical decision support to minimize weather-related delays, improve safety, and streamline coordination between onshore and offshore personnel.
Why ODST?
Picture yourself on an offshore construction vessel in the middle of a critical operation. The weather is turning, and the decision to proceed or abort lies in your hands. The process is familiar: Gather analysis reports, study operational limits, analyze weather forecasts, and present a convincing case to vessel operation managers—all in a very short time frame.
The risks are real—a misinterpretation could lead to missed opportunities, costly delays, or worse, unsafe conditions.
ODST tackles these challenges by providing real-time, data-driven decision support, replacing assumptions with accurate weather forecasts and vessel-specific insights. By automating weather assessments and integrating live vessel response data, ODST enables crews to make faster, more precise decisions, improving efficiency while ensuring safety and alignment across onshore and offshore teams.
-
ODST combines high-resolution weather datasets with advanced analytics, enabling more precise planning and utilization of available weather windows.
-
Enhance safety and avoid unnecessary risks by empowering the crew to make informed decisions based on live data sets validating weather forecasts, and vessel motion predictions.
-
Speed up decision-making for upcoming activities. Through automation and quality-assured insights, ODST provides users with consistent GO/NO-GO recommendations well in advance.
-
Identify opportunities to optimize the vessel schedule. By understanding vessel operability under different conditions, ODST helps to sequence activities to maximize vessel efficiency.
-
Streamline communication between offshore and onshore teams. ODST provides a shared and consistent overview of operational conditions, ensuring that all stakeholders are aligned in their decision-making.
Features
ODST is developed in collaboration with the industry to reflect real offhore processes in activity planning and execution. Users can define weather and vessel motion-based criteria/limits relevant to the planned operating modes, resulting in GO/NO-GO decision support many days in advance. ODST advises on operating windows for optimal activity execution including recommendations on the best possible vessel heading.
Easily accessible and actionable insights are provided by ODST through an intuitive user interface. Designed for both onshore and offshore stakeholders, the interface offers a layered degree of detail, allowing you to easily navigate and make informed decisions.
