What is the Bridge Procedure Guide ?
BPG is a guide produced by the international chamber of shipping to assist and guide Navigators in passage planning, pilotage, and best practices to follow in cases of emergency.
it is split into annexes.
Radar Pre departure checks
The performance of the radar should be checked using the Performance Monitor before sailing and at least every four hours whilst a radar watch is being maintained
VRM Checked again range rings
ERBL cross checked again compass
Good radar practice:
The quality of the performance of the radar needs to be checked regularly. A performance monitor if fitted should be used for this purpose
Misalignement of the heading marker, even if only slightly, can lead to dangerously misleading interpretation of potential collision situations.
Small vessels, Ice, and other floating objects such as containers may not be detected by radar**
Video processing techniques should be used with care
Echoes may be obstructed by sea or rain clutter
Masts or other structural feartures may cause shadow or blind sectors on the display.
What 3 different types of information does AIS show?
Static
a. Length
b. Breadth
c. Call sign
d. MMSI
e. Type of ship
Dynamic
a. Course, speed of vessels and own vessel (GPS fed)
Voyage Data
a. Draught
b. Number of People
c. Destination and ETA
d. Navigational Status
BNWAS
Bridge Navigational Watch Alarm System
IMO Performance Standards = ANNEX 11 - Resolution MSC.128(75)
Automatic function
Manual On - Manual Off A
Audible Alarm between 3-12 mins
Second Alarm to senior officer or master
Third Alarm to ships crew (general alarm)
What is ARPA
Automatic Radar Plotting Aid -
Computerised calculation of the course and speed of the other vessel that gives CPA and TCPA
Also used in trial manoeuvres
How do you setup a radar?
Check no open PTW, no one aloft, visual check, no halyards in the way
Turn it on and turn all controls to zero
Adjust in the following order: BGTC (Big Girls Talk Crap) (Brilliance, Gain, Tune and Clutter)
Brilliance - is for ambient light
Gain - turn up until speckling effect and then turn back slightly
Tune - tune for best picture. Look for targets on outer edge of radar and tune to get best return for those targets. If no targets, then set to maximum deflection on the tuning bar.
Clutter - Sea and Rain. (Affects the radar from the centre outwards) When adjusting the sea clutter we are trying to get rid of the burnt area in the middle of the screen. Rain clutter suppresses over the whole screen and can also suppress small targets which is a danger. When searching through a rain cloud you should turn rain clutter on and then off again .
ECDIS What are the advantages and disadvantages of rastor charts - RNC’s
Advantages:
Exact copy of a paper chart
Familiarity in look and symbology
Good topographical detail
Cheaper to produce
World wide coverage
Disadvantages:
Can’t interrogate
Cannot be customised
Cannot zoom in, chart become pixilated
Large file sizes
Not seamless. need to load another chart if going off “edge”
ECDIS What are the advantages and disadvantages of Vector Charts - ENC’s
Advantages:
Charts may be rotated to any angle
File sizes up to 10 times smaller than RNCs
useful for correcting - easily downloaded via internet
Objects can be interrogated
Chart data may be shared with other equipment i.e. radar, AIS
You can zoom in and it is seamless - Layering eg. CATZOG when passage planning (Category zone of confidence)
Disadvantages:
Technically more complex
More expensive
Not worldwide coverage
Teaching and training takes longer and more expensive
Objects need to be interrogated to get information
Responsibilities with the pilot aboard.
Despite the duties and obligations of pilots, their presence onboard does not relieve the master or officer in charge of navigational watch from their duties and obligations for the safety of the ship. The master and the pilot shall exchange information regarding navigation procedures, local conditions and the ships characteristics. The master and/or officer in charge of the navigational watch shall co-operate closely with the pilot and maintain an accurate check on the ship’s position and movement.
