Abstract

Fremgangsmåte og anordning for suksessiv fjernfrakobling av holdere (6,6,6,6,6,6) som er tilkoblet med mellomrom. I langs en undervannskonstruksjon (3), idet anordningen omfatter en trekkekabel (20) som har en fortykning (21) på en ende og er fort gjennom hull aksialt gjennom midten av koblingstapper som holder deler av holderne sammen, hvilke tapper hver utgjares av to separate halvdeler som er lagt mot hverandre i et aksialt midtplan.Method and device for successive remote disconnection of holders (6,6,6,6,6,6) that are connected at intervals. Along an underwater structure (3), the device comprising a traction cable (20) having a thickening (21) at one end and fastening through holes axially through the center of coupling pins holding parts of the holders together, which pins each consist of two separate halves laid against each other in an axial median plane.
