10.4 Sensor tests


10.4.1 Any sensor whose performance is critical to MASS safety shall be tested and certified to give reliable results. As far as possible, this may be done for each sensor type; in some cases, the sensor performance is largely independent of the platform on which it is mounted.


10.4.2 Where indicated by the Risk Assessment, and where sensor performance is to some degree influenced by the platform on which it is mounted, sea trials shall be performed using the sensor/MASS combination, to test external and internal sensors in a real maritime environment that meets or exceeds the most demanding environments for which the MASS is to be certified.


10.4.3 In some cases, the dependence of sensor performance on the host platform is such that the tests may be performed using a representative platform, i.e. one where the sensor performance is expected to be equivalent or worse than on the MASS itself. This means that the sensor may be certified, on the basis of one set of trials, for many MASS platforms. In such cases, the critical parameters of the test and MASS platforms in question shall be recorded for comparison and justification. For example, if sensor performance depends positively upon antenna height above sea level, the test may be performed on a trials vessel using a lower antenna height, to provide accreditation for use on all MASS with higher antenna mountings.


10.5 Emergency Stop test


10.5.1 The Emergency Stop systems shall be tested, using all defined methods of triggering Emergency Stop, singly and in combination, and under datalink failure conditions, to demonstrate that the Emergency Stop system is fail safe.


10.6 Cyber security


10.6.1 Cyber security is defined as the protection of information systems from theft or damage to the hardware, the soft- ware, and to the information on them, as well as from disruption or manipulation of the data for the services they provide.


10.6.2 MASS shall have cyber security measures to protect sensors and control systems as far as practicable and necessary.


10.6.3 Key risks are identified as (but not limited to):


n Backdoors; n Denial of Service; n Direct Access; n Eavesdropping; n Tampering.


10.6.4 Key systems to be protected are those concerned with vital situational awareness and the display thereof (e.g. position sensors, heading sensors), control (steering, waypoint generation), operator override (including Emergency Stop provisions.
