Effective rationalisation of energy consumption can only be achieved if waste factors are identified in advance. Following the procedures defined in Sala et al. (2022), energy audits will be implemented to establish baselines in the area/gear combinations specified in Table 1 (see Inception Report attachment at the Deliverables page). DecarbonyT partners will perform energy audit surveys to: i) collect data and information in order to carry out an energy analysis of the harvesting operations; ii) process data collected and preparation of the audit reports; iii) identify areas of possible intervention. The energy audit surveys will be carried out on a sample of ten fishing vessels in each area/gear combination stratified by vessel length and engine power. Vessels monitored and evaluated in the pilot studies (Task 2) will be included in the samples of the ten vessels / area-gear combinations so that they will be used as a validation exercise of the Energy audit approach. 

A standard layout for the information collection will be discussed and settled during the first coordination meeting (Orientation meeting). 

Collect information on innovations that are targeting drag force reduction and fishing gear modifications (e.g., alternative designs of door, trawl net, ground gear). The review will explore those suggested modifications that are suitable to the fishing fleet in terms of innovation uptake. This should include the compilation and critical review of best practices in towed fishing gear operations. 

To compile, through reviews on existing technical literature and data on fuel consumption, information useful to determine which are the most energy efficient techniques and vessel characteristics in terms of catch per unit of primary energy will be gathered. 

Where available, information should be broken down by major fishery and by different metiers and vessel sizes. This information should, where possible, indicate how energy consumption is distributed among the different operations, including steaming, searching, catching, handling, and storing on board. The result would take the form of a catalogue of fishing gear and vessel characteristics and a quantification of their performance in terms of energy efficiency.
