CPA to be kept during day and night
When master is to be called
Watchkeepers fit for duty
Always maintain a proper lookout Rule 5
Voyage well planned and passage plan signed by all OOWs
At no time shall bridge be left unmanned
Handover checklist in practise
State 6 factors when deciding on the composition of a safe bridge watch
Visibility, sea state & weather
Traffic density
Activities in the area
Near TSS
Operational status of bridge equipment
Proximity of navigational hazards
Manual or autopilot
10 items of information during hand over of bridge watch
Relieving OOW fit for duty
Master orders signed
Position course speed
Proximity of nav hazards
Machinery status
Errors Gyro and Magnetic
Weather conditions
Work in progress on deck
GMDSS traffic
Logs complete and signed
Why clear bridge communication is important and example of good practise
Critical element of bridge resource management
Messages must be accurate and clear
Continuous Transfer of information in the bridge leads to safe navigation
Convey information in a clear and understandable manner in a common language
Ensure information/order was received
The receiver to report when action has been executed
Orders and reports on duties to be accurate and timeous
Instances when both lookout and OOW are required in the bridge
Poor visibility
During night hours
Increased traffic density
Proximity of nav hazards may make it necessary to carry out additional nav duties
Possible dangers when using VHF for collision avoidance
Uncertainty over identification
Language difficulties
Ambiguous messages
Time wasted trying to make contact
6 aspects lookout should be briefed on
Maintain continuous watch
Remain at his position until relieved
Proper handover to be done
No other duties shall be undertaken that can interfere with his duty
What to be expected on the watch
How to make reports
Describe four conditions that may lead to ice accretion
Sea surface temperature drops below 4 degreesC
Air temp is below the freezing point of sea water -2
Gale force winds ,force 5
Wind blown spray, rain and fog can freeze on contact
When would it be considered possible to run a solo watch keeping bridge?
In certain circumstances of clear daylight conditions, the master may consider that the OOW may be the sole lookout
Ensure that situation has been carefully assessed
Sole lookout should always be able to perform both the duties of a lookout and keep a safe nav watch
Support personnel must be immediately available
Available means of communication to summon assistance
Describe 3 ways ice accretion can make vessel unseaworthy
Describe 3 ways to prevent or reduce ice accretion
Increase of top weight will affect stability, vessel could capsize
Vessel becomes difficult to steer or steering failure
Increase of draught may cause more spray.
Reduce speed
Steam downwind
Seek shelter downwind from land
Purpose of SOPEP & ORB
SOPEP- Shipboard Oil Pollution Emergency Plan
An action plan with instructions and duties in case of a oil/fuel spill
Purpose is to guide crew in dealing with accidental spills
Oil Record Book
Account for all oil and sludge transfers and discharges on a vessel.
Authorities are able to monitor crew is properly disposing of oil discharges.
Taking on fuel alongside. Describe actions in case of an accidental spill
Cease bunkering, close valves
Contain spill
Commence clean up immediately
Inform harbour authorities
Record date/time/pos/approx amount spilled
Entry in OLB & ORB
4 stages of waste management
Collection
Processing
Storage
Disposal
Why would safety officer not let work commence
No permit to work
Observing unsafe practice
Incompetent or unqualified person
Poor conditions (rough weather, poor light)
6 aspects to cover on safety briefing
Location of muster station
Location of life jackets
How to don a life jacket
Location of life rafts
Emergency signals and how to respond
Location of nearest fire extinguisher
