Funded project

The aim of the ENERSENNE project is to optimise energy consumpion in Danish seining* by assessing fuel consumption for each of the operational stages of this technique: route, setting the nets, propulsion and hauling. 

In the course of the project, equipment was installed both on the boat and on the seine net: torque sensor, fuel consumption gauge, electric watt meter and vessel list and trim sensor. This equipment was managed by a central system which recorded the behaviour of the boat as well as the various aspects of its fuel consumption - motorisation, electricity, etc. The object was also to optimise operation of the seine net via an improved scenario.

By installing sensors on board a trial fishing vessel, the ENERSENNE project indentified a model for combined boat/fishing gear applicable to Danish seining.

As regards on-board measuring, the tests conducted highlighted the relative importance of route/fishing operation (same order of magnitude of consumption observed), and the energy required for each phase of the fishing operation (setting and hauling the nets). This information is of interest to shipowners and Danish seining activities.

ECOMER, an intelligent analytical econometer (co-funded by FEP), has demonstrated its full significance for this type of sea trial and was in this instance adapted to the Danish seine.

Several points of energy consumption were revealed during the fishing operations: 45% of consumption due to the seine rope, 39% to the trawl net and 16% to seabed drag). 

The traditional 'Danish seine' technique has seen a revival of interest: this energy-saving method results in better quality catches compared with bottom trawling.
