Abstract

En deflektor for forskyvning av en streamer som slepes ved sin innføring ved et seismisk undersøkelsesfartøy omfatter et vingeformet legeme som er forbundet til innføringen og formet til å frembringe en sideveis rettet kraft som tvinger innføringen lateralt i forhold til fartøyets bevegelsesretning. En bom som forløper bakover fra den vingeformede delen, og som danner en del av en anordning hvorved vinkelen for det vingeformede legemet i vann, og derfor sideveiskraften som frembringes av den, kan varieres. Den øvre del av det vingeformede legemet er direkte forbundet til undersiden av en langstrakt flottør.
