Seamanship (GSK) Flashcards
COSWAP, Anchoring procedures and precautions
Chapter 26.1/26.2
Additional instruction required on specific equipment
Appropriate control measures based on risk assessment
Responsible person in charge, competent seafarer running equipment
PPE and brief
Communications with bridge
Check for small craft/obstacles beneath bows, ‘walk out’ to waterline
COSWAP Mooring (making fast and casting off)
Chapter 26.3
Consider ANY precautions when undertaking this task on board:
PLUS
BREAST lines should take most of the athwart-ships strain
SPRINGS should take most of the Longitudinal strain (for and aft)
Very short lengths are to be avoided as they take more strain (EQUAL LENGTH EQUAL STRENGTH)
Very short lengths may be compensated for by running the line ON THE BIGHT

The five stages of a risk assessment
- Identify the hazards
- Decide on who might be harmed and how
- Evaluate the risks and decide on likelihood and consequences
- Record your findings and implement them
- Review your risk assessment and update if necessary
COSWAP Permit to work, Chapter 14
Contents/Principles applying to a PTW system
- Should be relevant and as accurate as possible:
Location of work, type, safeguarding measures - Period of validity, (not exceeding 24 hours)
Including any time limits - Only the work specified is to be undertaken
- Before signing, officer should ensure all measures are undertaken, procedures in place
- An officer taking over must sign to indicate transfer of authority
- The competent person undertaking the works should countersign
- On completion, competent person to notify the officer and close out PTW
- The competent person should not be the same person as the Officer

MGN 556 (M+F)
Safety signage and signals around vessels
Define enclosed space
IMO defines an enclosed space as having either or both of the following characteristics:
Has limited openings for entry and exit
Has inadequate Ventilation
Additionally:
Is not designed for continuous worker occupation
Define a Dangerous space
Any enclosed or confined space in which it is foreseeable that the atmosphere may at some stage contain toxic or flammable gases or vapours, or be deficient in oxygen, to the extent that it may endanger the life or health of any person entering that space
Textbook Beginning to ALL seamanship procedure responses
Complete toolbox talk
Complete relevant checklist
Undertake a risk assessment
Establish and test comms with the Bridge
Ensure appropriate PPE is worn
Area clear of hazards and adequately lit
Then follow on with job specific items
Checking and testing the Steering gear for departure/Arrival
Complete steering checks within 12 hours of departure /arrival
Call and inform engineers
Establish comms with engineers via emergency comms in Steering compartment
Engineers to visually inspect all steering gear for damage and leakage
Test isolation valves/shutoffs/alarms/local controls on Bridge
Test from Main console, FU, NFU, pumps 1 and two, and a combination of the two
Test time for hard over to hard over. No less than 28 seconds
Check Rudder Angle Indicator, and ROT indicator
Same process from each and all stations
Make a separate entry into the Bridge Log Book
Checklist for departure for sea example (equpiment)
Steering
Radar
ECDIS
Echo sounders
VHF Set to Local Traffic Information
Lights and shapes

Call ER to prepare ME’s for Master to test
Power on deck to machinery
Gangway and crew lists
Tide and weather info
Update AIS
Compass error
GMDSS

Hazards arising from working Aloft
Falling
Dropping items
Injury from radars moving
Damage to ears from horn
Injury from adverse weather
Inexperience
Level 1 Risk Assessment
Generic, broad range company RA
Level 2 Risk Assessment
Done on board, relating to specific tasks carried out on board
Level 3 Risk Assessment
A discussion between ALL involved parties
Level 4 Risk Assessment
A continuous and dynamic RA, done by us, the Mariners, on ourselves and the way we carry out our tasks

Optimum 20.8 %
24% too much
Less than 20% unsafe also
Preparations for entering Enclosed space
“Tool box talk
Risk assessment
Permit to work
Comms with bridge
PPE
Adequately lit”
THEN
Safely open the space to mechanically ventilate
Test for three types of gas
Sample space at multiple locations
Call Engineers to lock out / tag out
BA equipment for entry
EEBD for emergency escape
Personal gas detectors to be worn
Use of INTRINSICLY safe Radios
Close off during break periods and test air again after break
Close off permit post works and secure space completely
How to test air quality of an enclosed space
Test for three types of gas:
Oxygen - oxygen meter
Toxic Gases - Toxic Gas meter (multi) OR detector Tubes, Looking for gases to be within the Safe Time Exposure Limit (Daily Average)
Flammable gases - Explosimeter (combustible gas indicator)
Takes a sample of the atmosphere and makes a micro explosion within
Looking for 1% of the Lower Explosive Limit (LPL)
How to perform an Amplitude of the sun
(and Azimuth)
Check almanac for sunset/sunrise
Take Azimuth mirror to Polaris/Gyro repeater
Wait until the Sun is a semi diameter from the Horizon
Take bearing of the sun
Note time of UTC and the Latitude
Go into Norries, and find the declination of the sun
Use declination and Bearing to find the amplitude in the amplitude table in Norries
Convert this to a T bearing and compare to your Gyro/Compass
