Dynamic Offshore Warning Zone Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Offshore construction monitoring systems face inaccuracies in warning zone coordinates due to human error and environmental factors like sea currents, leading to potential collisions between vessels and mooring lines, which can result in false alarms or missed alerts.
Innovation Solution
A monitoring system that automatically updates warning zone coordinates based on input data specifying the platform and marine assets' positions, allowing operators to define dimensions rather than coordinates, thereby reducing the risk of collisions by maintaining accurate and up-to-date spatial ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual coordinate entry is used for warning zones, then initial setup is simple, but coordinate accuracy deteriorates due to human error and platform drift
Solution Approach 1:
The system automatically determines warning zone coordinates by retrieving platform position data from existing position determination means, eliminating manual coordinate entry. The coordinates are self-updated based on platform drift and movement, ensuring continuous accuracy without operator intervention.
Solution Approach 2:
The system continuously monitors platform position through position determination means and automatically updates warning zone coordinates based on detected platform drift. This closed-loop feedback mechanism ensures coordinate accuracy is maintained despite environmental factors like sea currents.
2Device complexity
If fixed warning zone coordinates are used, then system complexity is low, but reliability deteriorates due to platform displacement from sea currents
Solution Approach 1:
The warning zone coordinates are transformed from fixed static values to dynamic values that automatically adjust with platform position. The system continuously updates coordinates based on real-time platform location data, ensuring warning zones remain accurately positioned despite platform displacement from sea currents or other environmental factors.
3Extent of automation
If manual updates of warning zone coordinates are performed, then automation level is low, but productivity deteriorates due to frequent coordinate corrections needed
Solution Approach 1:
The system automatically retrieves updated platform position data from existing position determination means and self-updates warning zone coordinates without requiring operator intervention. This eliminates the need for manual coordinate corrections and ensures continuous monitoring accuracy.
Solution Approach 2:
The system maintains continuous updating of warning zone coordinates by continuously monitoring platform position. This ensures that the warning zones remain accurately positioned at all times, preventing both false alarms and missed collision warnings.
Data Source
AI summary
A monitoring system for monitoring an offshore construction is presented. The offshore construction to be monitored comprises mutually mechanically coupled marine assets. The monitoring system comprises a data storage unit, an intrusion detection service, an input device, and an update service. The data storage unit stores data specifying a spatial range of at least one warning zone pertaining to the offshore construction. The intrusion detection service is provided to detecting an intrusion of the spatial range and for issuing an alert message upon such detection. The input device receives position information for one or more of the marine assets. The update service updates the spatial range of the at least one warning zone based on the received position information. Additionally a monitoring method and a computer program product are provided.
