Resinex has specifically manufactured for Kigam (the Korean Institute for Geoscience and Mineral Resources), three big elastic beacons for instruments. They have been projected taking into consideration simulations using TetherBuoy 2 (a software for the numerical simulation of the dynamics of floating-moored structures), studied by Resinex with the cooperation of MOX (the Laboratory for Modelling and Scientific Computing). The elastic beacons were manufactured at the beginning of 2015 and delivered in Korea last May, then installed in July 2015 under the supervision of Resinex personnel, offshore the Korean oriental coast in the Sea of Japan, at a depth of 80 metres. The beacons are equipped with a huge turret (2×2 metres), able to host the power system (solar panels and batteries) and the electronic equipment which control the devices placed on the sea bed by Guralp Systems Ltd, for surveying the geophysical activity and the transmission of data to-land. Moreover, the beacon structure is more than 40 metres long and it is linked to the seabed through an anti-torsion wire rope ø 52 mm fixed to a concrete sinker of 25 tons. The three beacons are placed at the vertices of a triangle and spaced out 300 metres each other. Resinex quality and technology have fully satisfied the requirement of the well-known Korean Research Centre.
