Voyage Data Recorder (VDR)
Under regulation 20 of SOLAS Chapter V on Voyage Data Recorders (VDR), the following ships are required to carry VDRs:
Bridge Naviagation Watch Alarm System (BNWAS)
According to SOLAS regulation Chapter V Section 19, the carriage of Bridge Navigational Watch Alarm Systems (BNWAS) is mandatory for new ships and shall be phased-in for existing ships. Phase-in will be as follows:
S.E.A.S – Ships Email Alarm system
The “Ships Email Alarm System”, or “S.E.A.S”, is an automated alert system that will detect a change in status of specified equipment and raise the alarm at a remote location, using a designated e-mail address.
- The system could be connected to the vessel’s holding tanks. When the high level threshold is reached the SEAS would detect this and automatically send an e-mail to Superintendant who could contact the vessel to ensure the matter is in hand.
- The vessel could have a fire in the engine room. The SEAS may be configured to detect this alarm and immediately dispatch an e-mail to the vessel’s office to inform them of the situation.
- For vessels with a single man bridge system if the watch keeper alarm is activated this can alert the vessel’s office or Master on-board.
A ‘Free Text’ tool is incorporated for the officer on watch to send a short note to the same e-mail address (and only this address) to update the Superintendant, office or whoever is the chosen recipient of the situation on-board.
The system will monitor a variety of inputs so an example of a vessels configuration could be as follows:
1 – Main Fire Alarm
2 – Engine Room Fire Alarm
3 – Cargo Hold 1 High Water Level
4 – Cargo Hold 2 High Water Level
5 – Engine Room Bilge High Water
6 – Generator Room Bilge High Water
7 – Watertight Door Status
8 – Bow Shell Door Status
9 – Stern Shell Door Status
10 – Steering Gear Failure Alarm
11 – Man Overboard Alarm
12 – Security Alert Activation
Status indications such as rate of turn limit and off course alarm, among others, can be monitored by adding further AMI interfaces such as the KW991.
KW991-CR – Course Recorder from AMI Marine (UK)
The KW991-CR Course Recorder with printer can be used as a direct replacement for old electro-mechanical type course recorders.
The display can be switched between:
* Tape heading display of 25 degrees,
* Digital display with GPS Information display,
* Large digital display
GPS and gyro heading is input to the KW991-CR and the printer will display the following:
* Gyro heading
* Speed over ground
* UTC time
This information is printed in plain English for the operator to read.
The 360:1 Synchro, stepper and NMEA heading sentences are accepted by the KW991-CR and, in addition to the printer output, all data is output in NMEA 4800 baud format from a second output port
