Incas integrated navigation and collision avoidance system

Abstract: The Integrated Navigation and Collision Avoidance System (INCAS) is designed to improve the safety and efficiency of ship operation by increased automation of the navigation and collision avoidance functions. It is intended that the navigator's knowledge and judgment be augmented by the preprogramming of all known information relating to the selected route and by the continuous and automatic assessment of dangers represented by passing vessels and other obstacles to navigation. The system utilizes a general purpose digital computer, which operates as a central processor for the data provided by the shipboard sensors. The information resulting from this integration and computation is displayed to ship personnel in a form which is easily understandable and requires no operator manipulation or calculation; automatic alarms are also provided. The data compilation and computation, coupled with displays and alarms, restores the watch officer to his decision making role and leaves him unburdened to properly ensure the safety of his vessel. Due to system design, the central data processor may be expanded to operate with other sensors to perform additional tasks.

Historical approach to marine collision avoidance

Abstract: This paper traces the history of the effort made by those interested in the shipping industry to reduce the loss of life and property caused by marine collisions. It cites the efforts of governments in establishing laws regulating the Rules of the Road, practices of seaman at sea, and in port, and the efforts made by industry and regulatory bodies to make radar an efficient tool for collision avoidance. It describes the latest developments to make use of the digital computer in conjunction with radar and describes the future use of satellites for traffic control and marine communications.

Collision Avoidance by Manœuvre

Abstract: In the Interim Report of the Institute's Collision Regulations Working Party (Journal, 23, 448), it was stated in the preliminary that Dr. Calvert was not able to subscribe entirely to propositions (1)to (19). Dr. Calvert here states his views.My disagreement with the interim report is concerned only with the propositions and principles at the end. The body of the report I regard as masterly in the circumstances.

On barriers in a problem of collision avoidance

Means for testing the operation of collision avoidance systems

Abstract: An apparatus for improving the testing of synchronized collision avoidance equipment including apparatus for simplifying obtaining a synchronized condition of the equipment being tested and apparatus making possible the selection for evaluation of a plurality of individual sets of simulated test conditions for test purposes. The present apparatus also makes possible the simultaneous testing of any number of collision avoidance systems within line-of-sight range of the test apparatus.

Automation of Merchant Ship Navigation Systems

Abstract: Use of automated merchant ship navigation systems is presently under evaluation by several ship operators. Evaluation includes definition of practical shipboard requirements and appraisal of economic benefits projected for positioning, collision avoidance, and complete conning systems. This paper reviews the systems under evaluation, rationale that stimulated the present evaluation, and projected trends in shipboard automation.
