Abstract
Abstract A ship navigation and handling training simulator comprises a console for use by an instructor and a console for use by a student navigator. Each console has a visual display unit with a screen to provide a mimic display of the ship and environmental information, and the instructor console is associated with two groups of controls for setting in, respectively, the environmental and display information applicable to the navigational or ship handling exercise to be performed and information representing ship/tug control decisions by the student. The consoles are interconnected by a voice link so that the instructor can initially set the environmental and display controls and subsequently adjust the group of controls for ship/tug control in accordance with vocal instructions from the student transmitted via the voice link. Computer means are programmed to control the displays on the screens on a time scale in accordance with the information set-in on both groups of controls and the changes thereto during the course of the exercise.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
130 words
A ship navigation and handling training simulator comprising a first console for use by a student trainee and a second console for use by an instructor, at least one of said consoles having a screen to provide a mimic display of the ship and environmental information, two groups of controls for setting-in respectively the environmental and display information applicable to a navigational or handling exercise to be performed and information representing ship/tug control decisions by the student trainee, said second console being associated at least with the said group of controls for setting-in environmental and display information, and computer means programmed to control the display on a time scale in accordance with the information set-in on both said groups of controls and changes thereto during the course of the exercise.
Claim 2
Dependent Claim
130 words
A ship navigation and handling training simulator comprising a first console for use by a student trainee and a second console for use by an instructor, at least one of said consoles having a screen to provide a mimic display of the ship and environmental information, two groups of controls for setting-in respectively the environmental and display information applicable to a navigational or handling exercise to be performed and information representing ship/tug control decisions by the student trainee, said second console being associated at least with the said group of controls for setting-in environmental and display information, and computer means programmed to control the display on a time scale in accordance with the information set-in on both said groups of controls and changes thereto during the course of the exercise.
Claim 3
Dependent Claim
33 words
A ship navigation and handling training simulator according to claim 1, wherein each of said consoles has a screen and both console screens provide an identical display at least of the navigational data.
Claim 4
Dependent Claim
32 words
A ship navigation and handling training simulator according to claim 3, wherein the display of certain instrument readings and computer generated messages is optionally restricted to the display at said second console.
Claim 5
Dependent Claim
74 words
A ship navigation and handling training simulator according to claim 1, wherein both said groups of controls are associated with said second console so that no manually-operated controls are accessible to the student trainee, and both consoles are interconnected by a voice link so that the instructor can initially set the environmental and display controls and subsequently adjust the group of controls for ship/tug control in accordance with vocal instructions from the student trainee.
Claim 6
Dependent Claim
53 words
A ship navigation and handling training simulator according to claim 4, wherein three vocal communication devices are provided for selective use by the student trainee and respectively simulate an internal telephone (to main control positions), a VHF telephone (to tug and berthing masters) and a talkback system (to the bridge of the ship).
Claim 7
Dependent Claim
69 words
A ship navigation and handling training simulator according to claim 5, wherein only one communication device is provided at said second console for use by the instructor for communication with the student trainee at said first console, the equipment used detecting and indicating which of said three communication devices is in use by the student trainee and automatically connecting it to the single communication device used by the instructor.
Claim 8
Dependent Claim
55 words
A ship navigation and handling training simulator according to claim 1, wherein the tug controls of the corresponding said group of controls are provided on separate modules, so that other student trainees can remove such modules and individually assume the roles of tugs masters each of whom is in vocal communication with said first console.
Claim 9
Dependent Claim
30 words
A ship navigation and handling training simulator according to claim 1, wherein controls are provided operative to select the scale at which the exercise is presented in the display thereof.
Claim 10
Dependent Claim
78 words
A ship navigation and handling training simulator according to claim 1, wherein a cursor device is adjustable relative to the display screen for positioning of the display on the screen and at the relevant time during berthing definition the computer is operative to control the position of the centre of the ship on the screen so that it coincides with the cursor, thus allowing any initial ship position to be selected relative to the remainder of the display.
Claim 11
Dependent Claim
40 words
A ship navigation and handling training simulator according to claim 1, wherein recording means enable an exercise to be recorded for subsequent replay, and the time scale is selectively variable in respect of both an exercise and the replay thereof.
Claim 12
Dependent Claim
39 words
A ship navigation and handling training simulator according to claim 1, wherein said group of controls relating to ship/tug control has the controls thereof arranged in three sections respectively relating to ship control, tug control and mooring rope position.
Claim 13
Dependent Claim
53 words
A ship navigation and handling training simulator according to claim 1, wherein artificial time lags are introduced, in order to give a more realistic response whenever any change is made to the ship controls and in respect of changes in the tug controls, other than a Rope On/Rope Off control simulating rope failure.
