    Abstract: The invention is a guidance system used in laying undersea pipe or cable from a pipe-laying vessel when radio transmissions are unreliable. The system processes parameters derived from sensors normally aboard a pipe-laying vessel and sensors cooperating with active winches applying tension to the several anchor lines. The vessel's pitch, roll, and heading angles are supplied from gyrocompass and vertical gyroscopic instruments. Anchor line elevation and azimuth angles with respect to deck coordinates are yielded by conventional angle pick offs associated with fairlead devices, as are the line axial tension and the length of anchor line paid out. Initial conditions, including the initial position of the vessel, are easily obtained in the usual manner. From certain of these parameters, the invention derives intermediate anchor line parameters for use in computing fairlead motion.The intermediate data is used to compute compensated fairlead motion data by first computing apparent fairlead motion from anchor line tension changes. This version of fairlead motion contains undesired terms due to apparent fairlead motion caused by anchor line length changes and also due to actual fairlead motion caused by vessel attitude changes. Therefore, second and third computations are made of the contributions of the latter effects. This is done so that apparent fairlead motion due to anchor line length change and actual fairlead motion due to vessel attitude change may be subtracted from the measure of apparent fairlead motion as calculated from anchor line tension change, yielding the desired compensated fairlead motion value free of significant disturbing components. An estimated value of vessel position change is then obtained by a least squares estimation involving these fairlead motion terms. Correction of vessel position then follows by cooperative operation of the winch and thruster assemblies.

    Abstract translation: 本发明是一种用于在无线电传输不可靠时从敷管船敷设海底管道或电缆的引导系统。 该系统处理通常在管道铺设船上传感器的传感器参数，以及与主动绞车配合使用的传感器，以向多条锚索施加张力。 船舶的俯仰角，俯仰角和航向角由陀螺罗经和垂直陀螺仪提供。 相对于甲板坐标的锚定线高程和方位角通过与导线装置相关联的常规角度拾取产生，线路轴向张力和锚线长度被支付。 初始条件，包括船舶的初始位置，很容易以通常的方式获得。 从这些参数中的某些参数中，本发明导出中间锚线参数以用于计算平行线运动。 中间数据用于通过首先计算锚线张力变化的明显的弹道运动来计算补偿的交错运动数据。 由于由锚线长度变化引起的明显的导线运动，并且由于船只姿态变化引起的实际的弹道运动，这种版本的导弹运动包含不需要的术语。 因此，第二和第三次计算是由后一种影响的贡献。 这样做，使得由于锚线长度变化引起的明显的导线运动和由于船舶姿态变化引起的实际的弹道运动可以从根据锚线张力变化计算的表观运动轨迹运动的测量中减去，产生没有 显着扰乱组件。 然后通过涉及这些弹道运动项的最小二乘估计值来获得船舶位置变化的估计值。 然后通过绞车和推进器组件的协同操作来修正船只位置。

    Abstract: The navigation system permits remote maneuvering of a water-borne structure about a stationary object by utilizing dual sonar ranging. The structure can be self-propelled or towed by a surface craft. The transducer portion of the navigation system is mounted on the structure and the system's remaining portion is on the deck of the surface craft. For complete remote navigation, at least three but preferably four transducers are employed for positioning at the four corners of a rectangle. Each transducer is both sound-emitting and sound-receiving. The sonic impulses from each pair of port and starboard transducers are directed downwardly and inwardly. The travel time for each reflected sonic impulse is directly proportional to the slant range between the transducer and the object. The spacing between each pair of port and starboard transducers and the frequency of the emitted sound impulses are selected so that very accurate measurements are obtainable of the position of the object relative to the transducers. If the object is a pipe it is desirably maintained on a visual display in a longitudinal plane of symmetry for the two pairs of transducers. Any appreciable lateral deviation from the desired position is immediately detected and corrective action can be taken by the surface craft to reposition the structure.

    Abstract: Apparatuses and methods are provided herein for performing marine auto-ranging. Marine auto-ranging may include the functionality to determine current conditions associated with a watercraft (e.g., remaining fuel, location, speed, wind, current, etc.) and determine a range for the watercraft and, in turn, possible destinations for the watercraft that are within range on a map. A marine electronic device may be configured to display a map and overlay the map with an indication of how far a watercraft could travel based on such current conditions, such as a highlighted or shaded geographical area around a current location of the watercraft on the map.

    Abstract: A computer 11 of a ship monitoring device 1 arranges one kind of transmission data between, two consecutive start control codes and two consecutive termination control codes. The computer 11 also arranges information indicating a type of the transmission data between the transmission data and the start control codes and between the termination control codes and the transmission data. In this way, the transmission data is transmitted in form of packet data. Therefore, transmission data in information communication between ships and sensed information in information, communication of fenders can be easily distinguished from each other. In addition, a type of information transmitted as the transmission data can be easily identified.
