Decision-support System for Ships in Degraded Condition

DSS_DC develops decision-support tools for handling crisis situations onboard cruise ships, oil tankers and other ships. The situations covered are problems in propulsion systems, hull damage and intentional grounding – including in adverse weather conditions. Co-operation tools for use onboard and between ship and shore will also be developed.

The following are the main technical and scientific objectives of DSS_DC:

1. Develop a model for interaction and co-operation between onboard and onshore decision-makers in an emergency.
2. Perform an analysis of onboard alarms and propose how alarm handling can be integrated in the overall decision-support system (e.g. through alarm priorities, risk-based alarm hierarchies, etc.)
3. Develop a computer and network architecture for implementation of the co-operative decision-support system. This shall support all DSS_DC modules as well as existing systems on ship and land.
4. Develop a prototype ‘multi-function console’ (MFC) that integrates the decision-makers’ interface requirements (see objective 1) as well as supports the ship/shore co-operation model from objective 1.
5. Develop a decision-support (DS) module for ships with degraded manoeuvring and/or propulsion systems. Support both immediate operational requirements as well as a ‘what if’ type analysis. Weather effects shall be considered.
6. Develop a DS module for assessing the effects of hull damage under various operational and weather conditions. The module covers hull strength and damage propagation. It will be able to give operational advice on changes in speed, course and ballast distribution.
7. Develop a DS module for intentional grounding and for advice after an accident. It shall be able to give predictions on hull damage and pollution (from cargo and bunkers) in case of grounding (being afloat afterwards) and stranding (being stuck). Weather effects shall be considered.
8. Develop a DS module for immediate assessment of current status and trends in the propulsion system’s technical condition. The module will make use of a hierarchical system of technical condition indices (TCIs) that will make it possible to assess functional consequences of component degradation as well as trace the consequences back to the component(s) causing the degradation.
9. Develop weather and sea routing functionality that can interact with the degraded manoeuvring DS module to provide overall ship routing in all conditions. There will also be interfaces to the hull damage module to allow the inclusion of weather conditions and forecasts.
