F: Cargo Work Flashcards
What is required in shippers declaration for bulk cargo?
1) Description
2) Type and Dangers
3) Handling
1)Description Characteristics Density / Stowage Factor Angle of repose Moisture Content Transportable Moisture Limit
2) Type and Dangers
Cargo Group as per IMSBC A,B,C
Class - Whether it is a dangerous good in bulk or not.
Hazards
Emergency Procedures / Medical First Aid / Contacts
3) Handling Stowage / Segregation Hold Cleanliness Weather Precautions Ventilation Loading/Discharge Method Carriage requirements Clean up
General Rule for Ventilating Cargo Holds with Bulk Cargo?
If hold temperature is higher than outside atmosphere you should ventilate.
If the hold temperature is cooler, and you introduce warm moist air, it will cool in the hold, condenstate, and form Cargo Sweat.
In general don’t want to cool air below its dew point in cargo hold. will form water.
What is the purpose of a draft survey?
To find the displacement of the vessel at any given point of time.
We can then determine the amount of cargo loaded or discharged.
- Subtract lightweight
- Subtract deadweight that is not cargo (ballast, stores, fuel)
Initial Draft Survey:
Determines the constant.
Intermediate Draft Survey:
Determine shore scale error.
Work out how much has actually been loaded vs what the shore scale has loaded.
Final Draft Survey: Comprises of 2 or three continual surveys Determine the trimming Quantities Determine final amount to load Determine total amount of cargo
What are the types of Cargo as per International Maritime Solid Bulk Cargo Code?
Type A: Cargoes which may liquefy
Type B: Cargoes which possess a chemical hazard
Type C: Cargoes which are neither type A or type B
What must you do before you load Solid Bulk Cargo?
Receive shippers declaration, and check the IMSBC code.
The shipper must provide specific information for it: Angle of repose, density, stowage factor, size, class, Hazards, Handling / stowage, ventilation etc. (to master and port of loading)
If it is of type A or type B, its carriage must be approved by
1) Flagstate
2) Port of Loading
3) Port of Discharge
If it is type C, it is authorised to be carried. The flag state and port of unloading notified.
What Publications would you use in order to load grain?
International Grain Code
BLU Code (Code of safe practise for loading and unloading bulk carriers)
Marine Orders Part 33: Cargo Handling Grain
Document of Authorisation to load Grain (Evidence vessel complies with the grain code)
AMSA FORM Notice to Load Grain: Amsa <72 Hours
Solas Ch VI Part C: Carrying Grain
Approved Grain Stability Book: Grain Stability Calculations (AMSA FORM provided) & Shear Force and Bending Moment Calcs
Loading Plan
What is Flow Moisture Point?
FMP: The amount of Moisture Content that will cause a Solid Bulk Cargo to start behaving like a liquid.
This will cause Cargo to shift and vessel to list (reduce GZ, Increase Draft, Reduce Deck Edge immersion Margin). Cause more subsequent shifting.
Or Free Surface effect, Cargo moving around holds like a liquid.
Precautions to take when loading Bulk Cargo?
Shippers Declaration - Check: FlowMP, TML, Moisture Content, Angle of Repose, Stowage Factor, Type of Cargo A/B/C, Chemical Hazards, Other Precautions
Check cargo with appointed surveyor (ie, it is as said to be - e.g not wet)
Check Cargo Stowage Plan - Filled hatches / Partly Filled
Trim Cargo - reduce cargo shifting
Do not load in rain
Hatch Covers are sealed correctly
Holds Cleaned
Bilges clean, covered with Burlap, monitored regularly at sea after loading and pumped as required.
What Markings would you expect on a container?
CSC Plate
For Dangerous Goods: Placard on Each Side and End of the container with Primary and Subsidiary Risk
For Marine Pollutants: Placard on Each Side and End
Dimensions of a container?
Width 2.4m
Length 40ft: 12m
Length 20ft: 6m
Height 2.5m
What are the 9 Classes of Dangerous Goods?
Every Good Lad Sips On Toxic Rum Coke and Malibu
Class 1 Explosives Class 2 Gases Class 3 Flammable liquids Class 4 Flammable solids Class 5 Oxidizing substances and organic peroxides Class 6 Toxic and infectious substances Class 7 Radioactive material Class 8 Corrosive substances Class 9 Miscellaneous dangerous substances and articles
