A method to determine a presence or absence of water in a cavity of a starter block having a non-horizontal surface of DC casting equipment including emitting a wave using a device containing a sensor, the wave propagating along a virtual beam path, directing the wave towards the cavity of the starter block such that the wave is reflected on a horizontal surface of the water, if water is present in the cavity, or is reflected on a non-horizontal surface of the cavity of the starter block, if no water is present in the cavity, detecting the reflected wave using the sensor, or not detecting the wave using the sensor, determining that there is water present in the cavity if the sensor detects the reflected wave, and determining that water is absent in the cavity if the sensor does not detect the wave while the sensor emits the wave.

Control device () for controlling the position of an instrumented cable towed in water, such as a marine seismic streamer, and/or an instrumented towed cable array (streamer array) with the possibility of controlling the individual instrumented cables both with in shape and position in relation to other instrumented cables and by that counteract cross currents and/or other dynamic forces which affect a towed array behind a seismic survey vessel, which control device () is provided with one or more acoustic means, such as acoustic transmitter/receiver elements (), arranged to or integrated in the wings (), main body () or motor and drive gear housings () of the control device for determination of position and distance.

Control device for positioning an instrumented cable towed in water

A control device (O,) for controlling the position of an instrumented cable towed in water, such as a marine seismic streamer, and/or a towed instrumented cable array (streamer) with the possibility to control the individual instrumented cables, both in shape and position, in relation to other instrumented cables and by that counteract cross currents and/or other dynamic forces which affect a towed array behind a seismic survey vessel. The control device () is adapted for plain and rapid mounting and demounting so that the streamer easily can be deployed and recovered, and in an easy way be reeled onto and out from a drum. The control device is further entirely or partly arranged for wireless/contactless transfer of energy and/or communication, i.e. signals/data, between a main body and wings. The control device, motor and drive gear housings () provided with wings () or wings () house drive means (), power supply (), electronics and sensor means.
