Abstract: Dynamic positioning systems and methods for controlling thrusters of a vessel. A dynamic positioning system includes a controller configured to predict position and heading of the vessel and efficiently control the the thrusters based on the predicted position and heading.

Abstract: A data fusion architecture with a plurality of sensors, optionally position measuring equipment (PMEs), is described. Each sensor supplies measurement data x1, x2 . . . xM and is associated with accuracy data H1, H2 . . . HM indicative of the accuracy of the supplied measurement data. Sub-processing units derives first estimates sf1, sf2 . . . sfM and second estimates Hn1, Hn2 . . . HnM of the variability of the measurement data supplied by the respective sensor. The first estimates are derived by processing the measurement data x1, x2 . . . xM and the second estimates are derived by processing the accuracy data H1, H2 . . . HM. The first and second estimates are combined in a multiplier to derive overall estimates σ1, σ2 . . . σM of the variability of the measurement data supplied by the respective sensor. Data fusion means such as a Kalman filter combines the measurement data supplied by each sensor and the overall estimates σ1, σ2 . . . σM for each sensor.

Abstract: A taut cable with a fiber optic cable with Bragg diffusion gratings allows a suitable driver circuit to determine the shape of the taut cable at a large number of points along its length. This enables the total 3-dimensional shape of the taut cable to be estimated and from which the position of the vessel relative to a seabed weight attached to the taut cable can be inferred.
