Bridge Exam Flashcards
Bridge Logbook
Check the bridge logbook for pre-arrival/departure test, per §164.25.
Check logbook for dates of emergency steering drills (if not conducted quarterly, then 48 hours prior to entry.)
Confirm Emission Control Area (ECA) compliance (verify engine room and bridge logs are identical.) .5% max and .10% ECA
Publications
A ship’s publications can be electronic, but ensure they are:
• Up-to-date.
• Written in a language understood by the navigational officers.
Publications to check for include:
- Verify presence of current, applicable and corrected charts and/or ECDIS
- Verify presence of current and applicable Tide Tables
- Verify presence of current and applicable CG Light List
- Verify presence of current and applicable Tidal Current Tables
- Verify presence of Inland Nav Rules
- Verify presence of COLREGS
- Verify presence of current and applicable U.S. Coast Pilot
- Verify presence of Intl. Code of Signals
- Verify presence and contents of maneuvering fact sheet
- Verify presence of Intl Aeronautical & Maritime SAR (IAMSAR) Manual Vol. III
Charts
Ensure navigational charts are corrected, up-to-date, and appropriate scale for the areas transited. If the primary means of navigation is ECDIS, verify that a secondary independent source of power is provided.
Charts should be updated weekly IAW Notice to Mariners
SOLAS Drills Record
- Verify crew members participated in abandonment and fire drills (monthly/25% or more of crew changeover)
- Verify drills includes operating Davits used for launching liferafts (<4 months)
- Verify different life boats are used for each drills
- Verify lifeboats and rescue boats are launched and operated (Quarterly)
- Examine training records for davit launched liferafts
- Verify records of enclosed space entry and rescue drills (2 months)
- Check to make sure SOLAS drills are conducted, if not done during the initial meeting (administrative exam).
- Check lifeboat logs for maneuvering in water (every 3 months)
Steering Test
- Witness operational test of steering gear controls
- Verify rudder angle indicator is accurate and consistent with local indicator
- Verify operation of loss of power alarm
- Verify operation of low hydraulic fluid alarm
- Verify contents of the steering gear instructions
- Confirm gyro repeater, communications, rudder angle, and alarms tested.
- Perform steering test as crew would normally test; ensure all pumps are activated, rudder moved port to starboard and all modes of steering tested.
Best practice: Ask the crew how they test their steering gear in order to ensure each pump is in working order. Each pump needs to be started and secured from the bridge. Keep in mind the bridge control is an electric means of controlling the local pumps. Verifying the rudder port and starboard movement is sufficient. Test the 30 to 35 degree time on the bridge in 28 seconds. Verify power failure alarm and low-level oil alarm, both audible and visual.
Non follow-up
requires positive control at the helm, as it bypasses the feedback between the helm and steering gear
Follow-up
entails moving the helm control to the desired degrees port or starboard; the steering gear moves up to that designated setting. Follow-up is often used with auto pilot.
Emergency Fire Pump
Witness operation of two hoses located furthest and highest from pump and ensure there is adequate pressure from the hydrant.
* Ask location of the emergency fire pump*
Ensure the emergency fire pump is the only one operational when being tested.
In this case, verify the indicator light is on for the emergency pump only.
Radar - X-Band (9 GHz) preferred for close in work (Piloting, local traffic) and S-Band (3 GHz) radar including Automatic Radar Plotting Aid (ARPA)
- Verify Presence and type
- Witness operational test
- Verify independent operation (10,000 GT and more = 2nd Radar System)
- Witness operational test of the ARPA (target acquisition)
Radars display a picture of surrounding objects and land by receiving a return signal that is transmitted. ARPA is software that interprets these signals and the objects that get “pinged” in the process. This information can be processed by the ARPA to give an object’s speed, distance, course and closest point of approach. A target that is identified by a double bracket or square represents an ARPA acquired target. A target that is identified by a triangle represents an Automatic Identification System (AIS) acquired target and displays amplifying information such as the ship’s name and Maritime Mobile Service Identity (MMSI) number.
- Secure AIS feed and acquire target using ARPA and account for bearing, speed, distance.
- Acquire same target using AIS feed and compare information.
SART transmission
SARTS transmissions are only received on X-Band, unless AIS SARTS.
Do not have crew energize radar if cargo operations prohibit. Pilot card can be referenced to verify operational condition of radars.
GMDSS
- Verify appropriate equipment for assigned sea areas (1,2,3, or 4)
- Examine Radio records
- Verify emergency source of power ( Battery room inspection)
- Verify stowage of SART
- Verify operation of NAVTEX
- Verify operation of INMARSAT ship earth station
- Verify installation of 406MHz EPIRB ( expiration, have the crew test)
Emergency communication equipment discovered inoperable or missing could warrant a detention in some cases if not reported.
• Verify operational test of DSC per GMDSS logbook or administration requirements (ship-to-shore or ship-to-ship).
- Verify the International Code of Radio Signals. Use the code to determine coastal station MMSI#.
- Ensure test is not a self or loop test by MMSI#.
- INMARSAT – Ship Security Alert System (SSAS) and LRIT are usually transmitted through INMARSAT.
- NAVTEX functional – Verify through logs/receipts. INMARSAT can provide NAVTEX information by manually retrieving.
- Search and Rescue Locating device.
- Check SARTs battery expiration.
- If over 500 GT and fitted with freefall/stern launch lifeboat, one SART needs to be in lifeboat.
EPIRB 406 MHz
EPIRB works by satellite and is fitted with a float-free hydrostatic release unit.
• Check battery expiration on the unit.
• Category 1, self-activating.
• The test mode only ensures battery works. The manufacturer can limit the amount of times EPIRB is tested annually for battery preservation.
- tested annually
- Maintenance conducted every 5 years
Lifeboat Radios
Perform operational test of lifeboat radios and verify:
• High visibility color.
• Check power source.
- Batteries for the radios are normally intended to be replaceable by the user and are fitted with spare batteries. Verify spare batteries are not easily confused with other radio batteries not intended for distress situations.
- Batteries intended as non-user replaceable do not come with spare batteries.
- Examine radios to ensure no indication of usage. Radios need to support an operational life of eight hours.
Check spare batteries for emergency-use-only seal.
Sources of Energy
In the event of failure of the ship’s main and emergency sources of electrical power, the reserve source or sources of energy are capable of supplying power to radio communications.
Verify batteries are suitably housed, efficiently ventilated, and in serviceable condition. Ensure electrical fixtures are appropriately certified for safe usage for the vapors or gases likely to be encountered.
AIS
- Verify presence
- Witness operation
AIS displays ship’s particulars, such as call sign and ship’s name, and correct ship’s information. Verify the following:
• Ship’s navigational status.
• Crew members onboard.
• Annual test report, as per reference (ee), Guidelines on Annual Testing of the Automatic Identification System (AIS), MSC.1/Circ.1252 (series).
• Nearby ships.
• AIS usually has an input to ARPA.
