Watch Keeping Flashcards
When can an OOW stand Sole lookout
-Once the master has determined that with out doubt it is safe to do so.
- During clear daylight hours
- Account for the following factors
i. Weather
ii. Vis
iii. Traffic
Iv. Proximity to Nav hazards
V. Attention necessary when navigating in or near TSS
Vi. LAyout of the bridge
Vii. Arcs of vis
Viii. Radar equipment limitations
Ix. OOW workload, GMDSS, Logs and record keeping, Routine testing of bridge equip
X. Assistance must be immediately available.
What is the primary responsibility of the lookout?
To Report any hazards that may impair the safe navigation of the vessel. He is obliged to give his full undivided attention to the this dusty and should report the following to the OOW.
All ships regardless of size
Any light and navigational marks
Any floating objects
Any ice
Sand bank and navigation features
Derelicts and any other hazard considered dangerous to navigation
Malfunctioning of any of the ships lights.
What are the duties of the OOW while performing the navigational watch?
- Keep the watch
- Do not leave the bridge unless properly relieved
- Maintain the watch in the presence of the master
- Maintain the watch in the presence of a Pilot
- If in doubt as to PILOTS action request clarification, still doubt call master
- Call the master when in doubt
- Not undertake any other activities that would interfere with the watch
- NO distraction from personal devices
- Qualified helmsman at all times
- Hand steer in Res Viz, High traffic, hazardous Nav Situations
- Use radar at all times effectively
- Ensure the position of the vessel is continuously monitored by regularly fixing and cross referencing with other equipment.
- Keep proper record
- Keep GMDSS watch
What factors should be taken into account when Composing a bridge watch?
Fatigue
Weather and Viz
Proximity to navigational hazards adding additional tasks
Use and condition of navigational aids.
Autopilot.
Amount of radio duties
Unusual demands that may arise due to special operational conditions.
What are the STCW requirements for safe Navigational watch keeping.
There must be sufficient navigational officers onboard to;
- Plan and conduct safe navigation
- Maintain a safe navigational watch in accordance with STCW code
- Manoeuvre and handle the ship in all conditions
- Moor and unmoored the ship safely.
What are the requirements for safe Engineering watch keeping.
There should always be sufficient engineers onboard to undertake the following.
- Operate and monitor the ships main propulsion and auxiliary machinery
- Carry out routine maintenance
- Manage and perform fuel and ballast operations
- Meet the need to possibly undertake manual operation in case of automation and monitoring failure
- Respond to machinery in emergency situations
List of ways to manage fatigue
- Min HORs
- Limit time performing demanding tasks
- Nutritious food
- Night personal appropriate food
- Scheduling. Drills and work around rest periods
- Avoid hazardous tasks around circadian lows
- Emphasise Seafarers responsibility to sleep
- Allow communication time during handoves
Requirements of vessel if Watch keeping requirements can not be met.
MGN 315
Procedure and Contingencies in place to ensure the vessel is brought to or REMAINS in a place of safety until a safe navigational watch can be established. Delays in vessel departure may be necessary.
Requirements for the master to stand Navigational watch
Bridge manning should take into account the provision of sufficient Qualified OOW’s so that the MAster does not need to keep regular bridge watch, and can instead float between watches as necessary.
When to call the master

OOW duties at anchor
Lights Dayshape Sound signals Res Viz GMDSS Detect Anchor dragging Ensure second anchor ready Observe and record all vessel leaving and arriving Call the master Record (depth, seabed, amount of cable, transit and anchor bearings, weather) Post extra lookouts in res vis
OOW duties when berthed
- Gangway watch
- Apply ISPS
- Regular checks of moorings
- Lights
- Ensure watches handed over correctly
- Ensure all work being conducted in a safe manner
- Observe fire detecting apparatus and fire rounds
- Logbook
OOW Responsibility in Restricted Viz
- On set CALL THE MASTER
- Comply with COLREGS
i. Lookout
ii. Safe speed
iii. Engine ready for immediate manoeuvre
iv. Lights and fog signals - Post additional lookouts
- Use RADAR
- Engines on standby
Handing taking over the watch
Outgoing:
Ensure incoming capable, vision, rested
Inform of standing orders and amendments to PP
Not to handover if incoming incapable, or Manoeuvre underway
Incoming:
Vessel - Position, course and speed
- Intended route
- Faults (Nav equipment or Eng machinery)
- Dangers to Navigation
- Any upcoming events
Weather - Wind, Sea sea state, Tide, expected/forecasts, Viz
Nav equipment - Current status, Radar setup, ECDIS setup, Compass errors
Engineering - Current watch, Engine speeds and settings
Traffic - Location, Density and movement
Watchkeepers - discussion of expectations of them and instructions for upcoming watch
Master - Location
Logbook
Master instructions to then Engineering watch
- Shall react immediately to notices and instruction from the bridge
- Shall adhere to operational requirements and mot change anything with out permission form C/E
- Frequent rounds of the engineering space with particular awareness to indications that cannot be detected by the monitoring systems (smells, noises, vibrations)
- Keep appraised of Fuel, lube oils and ballast levels
- Monitor bilges and follow c/e orders for disposal
- Immediately Inform bridge of failure of equipment or any cases deemed necessary
