Method and system for providing an integrated long range, high capacity communication system between several entities involved in maritime Simultaneous Operations (SIMOPS). The method and system makes use of narrow lobe phase steerable antenna being controllable in both azimuth and elevation by software control.

Method and system for maritime high speed broadband communication networking

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), which control device () is provided with buoyancy means () for retrieving the control device () and instrumented cable to the surface, at least sections of the instrumented cable, which means () are arranged for providing the control device () with buoyancy.

Control device for positioning an instrumented cable provided with buoyancy means for retrieving the control device and instrumented cable from submerged positioning

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

System and method for controlling an instrumented cable () towed in water, such as a marine seismic streamer and/or an instrumented towed cable array (streamer array), to which at least one instrumented cable (), control devices () are arranged to control the individual instrumented cables () both in shape and position in relation to other instrumented cables () and then counteract cross currents and/or other dynamic forces affecting a towed cable array behind a seismic survey vessel (). The wings () of the control devices () are provided with acoustic transmitter/receiver means () and electronics for acoustic ranging, and the vessel () and one or more tail buoys () are provided with acoustic transmitter/receiver means () and electronics for acoustic ranging, and is provided with instrumentation for absolute position and velocity.

System and method for controlling the position of a instrument 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.

Device for controlling the position of an instrument cable towed in water

A method and control device for controlling the position of a marine seismic streamer spread and the ability for controlling individual marine seismic streamers both in shape and position relative to other marine seismic streamers and thereby counter effects from crosscurrent or other dynamic forces in a towed spread behind a seismic survey vessel. The system includes sensor means for determining information to control the streamer and a control device, including a housingmechanically and at least partly electrically connected in series between two adjacent sections of the streamer, at least three control membersprojecting from the housing, and control means adjusting the respective angular positions of the control membersso as to control the lateral and vertical position of the streamer. The rotational position of the streamerand control deviceis measured, and the measured rotational position is used to control the angular position of the control members, and thus the lateral and vertical displacement of the streamer
