Improved ship efficiency through use of energy storage systems

This project goal has been to develop a novel power storage device (HESS) for usage on board fishing vessels and other vessels. The device is intended to reduce emissions, fuel consumption and investment costs for combustion engines on board by use of energy storage devices which will smooth the power variations on the vessel engines, reduce power peaks and power the vessel in full electric drive. The required power and power variation has been identified in the project by usage of a data acquisition program. The data acquisition program has been used for development of the HESS and tools and methods for the design process and in operational conditions for both new vessels and retrofitting on board existing vessels. The HESS will reduce the total fuel consumption of the operation. A fishing vessel has been equipped with data logging equipment and operational data have been measured continuously since October 2017. The operational data are regularly transferred to SINTEF Marine Data Centre. Models for simulation of the vessel's energy system and for dimensioning of HESS has been developed together with a new grafical human interface. Methods and tools for extraction of representative time series from the operational data has been developed. A full scale lab test has been executed for testing of the new developed control algorithms with different energy storage technologies.The results from the test has been successful and the results are in line with the simulation results.

Hovedhensikten med prosjektresultatene er å redusere klima og mijøavtrykk samt bedre driftsøkonomien for fiskefartøy og lignende skip. Redusert energibruk ombord vil medføre bedre økonomi for eier og mindre utslipp av både klima og miljøgasser til luft. Ved å innføre verktøy som kan forbedre design av energisystem ombord i en tidligfase, vil en ha effekt av optimalisering gjennom hele levetiden. Fokus på energibruk, klima og miljø gjennom slike prosesser, er generelt viktig for å få industrien til å investere i slike løsninger.

This project aims to develop a novel power storage device for usage on board fishing vessels. The device is intended to reduce emissions, fuel consumption and investment costs for combustion engines on board vessels by maintaining a power reserve which will smooth the power variations on the vessel engines, reduce power peaks and power the vessel in full electric drive. The novel power buffer device is named a Hybrid Energy Storage system (HESS). The required power and power variation capacity will be identified in the project by usage of a full scale data acquisition program. The data acquisition program will drive both development of the HESS and tools and methods for including such devices in the design process for both new vessels and retrofitting such devices on board existing vessels. The HESS is intended to reduce the usage and load on the engines of the vessel and its usage must be designed while considering the operational profile of the vessel. Tools will be developed to quantify the real operational profile of a vessel based on full scale measurements. The derivation of the actual operational profile will be based on the same full scale logging system as used for definition of HESS capabilities and which supports future design processes. A case vessel will be used for data sampling.
