8 Functional requirements for INS task stations

  8.5 The allocation of the tasks to the task stations should be sufficiently flexible, to support all navigational situations, and should be sufficiently simple to support team working and awareness of operator roles. The selection of the task at the task station should be possible by a simple operator action.

Parent topic: Module B - Task related requirements for Integrated Navigation Systems

8.1 Number of task stations

  8.1.1 The number of task stations on the bridge depends on the tasks integrated into the INS. It should support the simultaneous operation and presentation of at least the minimum set of tasks necessary to meet the carriage requirements of SOLAS regulation V/19.

  8.1.2 To specify the required number of task stations the required backup arrangements as mandated by the carriage requirements of SOLAS regulation V/19 should be taken into account.

8.2 For each tasks of:

  • route monitoring
  • collision avoidance
  • navigation control data,

 a task station should be provided, if the respective task is part of the INS.

8.3 Additional tasks

 For the tasks of:

  • route planning,
  • status and data display, and
  • alert management,

 means should be provided to operate the tasks at least at one of the task stations referred to on paragraph 8.2 or at least at another additional task station at the choice of the bridge team and pilot.

8.4 Remote route planning

 For the task “Route planning”, a separate remote task station may be provided.

8.6 Track control

 If the function of track control is implemented in the INS,

  8.6.1 it should be possible to display the planned route graphically on the task stations for:

  • “Route monitoring”, and/or
  • • “Collision avoidance”.

  8.6.2 the control and operation of this function by the user should be possible via the task stations for:

  • “Route monitoring”, and/or
  • “Collision avoidance”.

8.7 Automatic control functions

  8.7.1 Task station with control

 Only one, clearly indicated task station should be in control of an automatic function and only one task station should at any time be assigned to accept control commands. It should clearly be indicated to the bridge team and pilot, if not otherwise obvious, which task station is in control of these functions.

  8.7.2 It should be possible to take over the control from a task station. In this case the set control values and limits should remain unchanged.

  8.7.3 The information relevant for the selected control function should be available for continuous display, at least upon a single operator command, and should in be presented when an automatic control function is activated or changed.

  8.7.4 Override

  8.7.4.1 It should be allowed by a single operator action to override or by-pass any automated function, regardless of the operational mode and the failure status of the INS.

  8.7.4.2 The INS should resume automatic functions only after an appropriate message and intentional operator action, considering all necessary starting conditions.
