Improved ship design and operation, by operational data aggregation, key performance indices and numerical optimization

Prosjektet har utviklet en demonstratorversjon av et skipsdesignverktøy. Basert på simulatormodeller av mulige komponenter i et designs energisystem, kan programmet finne hvilke komponenter som bør installeres for best mulig å passe designets forventede driftsprofil. Prosjektet har utviklet et system for logging av distribuerte målinger. Dette inkluderer både funksjonalitet for å innhente målinger, lokal lagring og sentral lagring. Det har videre blitt utviklet måltall (Key Performance Indicators) for å kunne tallfeste hvor effektivt et fartøys operasjoner er. Det har blitt utviklet metoder for å generere nye skrogformer basert på eksisterende skrog ved hjelp av 3D-morfing. Prosjektet har utviklet et verktøy for analyse av store mengder operasjonelle data, slik at disse kan tas i bruk til både forskning, designutvikling og beslutningsstøtte ombord. Resultatene fra prosjektet er allerede tatt i bruk i flere andre forskningsprosjekt.

The project can be summarized through the following tasks: WP1: Data acquisition and development of KPIs The goal of WP1 will be to create a prototype of the hardware and software necessary to acquire the measurements from the vessel systems, as well as to define some key performance indices (KPIs) able to reflect the performance of the vessel. 4.2 WP2: Development of unified ship models and state estimators based on acquired data The parts and subsystems of the vessel which are most important for its performance in relation to the stated objectives will be identified. This will typically include the vessel hull, the propeller, various engines, frequency converters, generators and so on. The identified components will be modeled at the accuracy require d to be useful for optimization, while their complexity is restricted increased computational effort associated. 4.3 WP3: Development of optimization strategies and tools for ship operation The simplest way to improve the ship operation with respect to chosen objectives, can be to develop a system providing the captain with relevant information, so that he can take informed decisions and design may be found using related methods. A more advanced solution will be to create a system able to advise the ca ptain of which actions to take. To achieve this, the concept of model predictive control (MPC) will be employed. 4.4 WP4: Development of optimization strategies and tools for ship design The objective of this work package is to create the tools necessa ry to optimize the design of a vessel, based on a suggested operational profile and a database of available ship components. 4.5 WP5: Development of prototype full-scale systems, case studies and verification The main activities in this work package will be to transfer the developed systems into prototypes of commercially usable products, and to verify their validity.
