Última Mission ORHAGO1, Mise au point d'un gréement de chaluts jumeaux pour les campagnes halieutiques ORHAGO ArchiMer Vacherot, Jean-philippe; Bavouzet, Gerard. The new ORHAGO campaigns, which aim to form a multi-year series of biological and ecological data, are relying on the use of twin trawls associated with a new type of rigging. The ORHAGO1 campaign should make it possible to make adjustments of the diverse elements of the fishing train in order to obtain an optimal configuration. This preliminary adjustment is indispensable for obtaining reliable data during ORHAGO campaigns. In order to do this, twin trawls of 25.15 metres, belonging to TMSI, were used jointly with the ship's panels (Morgère WS) and a clump specially developed for the occasion with the Morgère Company. In order to verify the correct behaviour of the device, the Scanmar setup monitoring system as well as Micrel tension and inclinometric...

A complete method is presented for determining the static and dynamic behaviour of a fishing gear. The net, which is very flexible, is modelised by a set of rigid bars. The hydrodynamic forces, applied to each bar, are determined by combining and generalizing the Landweber and Morison hypothesis. A CFD method is used to calculate the forces on trawl doors. The fundamental principle of dynamics is completed with length equations expressing the elasticity of the bars. It leads to a set of second order non-linear differential equations, which is solved using a Runge-Kutta method. We will now present a few examples of the various applications of our works : the study of the trawl gear equilibrium in a uniform flow, an example of manoeuvrability (gyration of...
