Which vessels does "Part 1, Division 3 – Grain Cargoes and Part II – Fumigation of the Cargo, Fumigation and Tackle Regulations" apply to? | a) Canadian vessels engaged in a voyage other than sheltered or near coastal 2
b) Vessels in Canadian waters that load or carry grain to a port outside the limits of an inland voyage
c) Foreign vessels in Canadian waters that are engaged or about to engaged a voyage other than an inland voyage. |
What are the minimum stability requirements set by the International Code for the safe carriage of grain in bulk? | a. GM> or equal to 0.30m.
b. Angle of heel due to a grain shift <12°.
c. The net or residual area between the heeling arm curve and the righting arm curve up to the angle of heel of maximum difference between the ordinates of the two curves, or 40° or the angle of flooding, whichever the least, shall in all conditions of loading be not less than 0.075 metre-radian. |
Definitions of grain, filled compartment and partly filled compartment | 1. grain - includes wheat, maize (corn), oats, rye, barley, rice, pulses, seeds and processed forms thereof, whose behaviour is similar to that of grain in its natural state.
2. any cargo space in which, after loading and trimming, the bulk grain is at its highest possible level.
3. any cargo space wherein the bulk grain is not loaded in the manner prescribed in A 2.2 or A 2.3. |
Describe the preparation of holds and decks for the carriage of grain. | 1. thorough cleaning
2. no trace of previous cargo
3. no loose rust/flaking paint (this includes hatch covers)
4. no previous cargo dirty stains on bulkheads, sides, and hopper plates
5. no live/dead insects in hold or weather deck
6. bilges clean and odour free |
What is the importance of trimming? | reduces surface area, reducing the possibility of spontaneous combustion by cargoes |
What are the securing methods for a partly filled compartment of grain cargo? | 1. saucers
2. bundling of bulk grain
3. overstowing
-drop removable tween decks on top of levelled grain
4. strapping or lashing
-wood floors with planks and lash the floors with wire
5. wire mesh strapping
-commonly used; wire mesh secures the grain |
Describe two ways two different bulk grain cargoes loaded into the same compartment can be separated. | a.) Jute or tarpaulin separation ; used mostly when the receiving terminal is equipped with a pneumatic unloading system.
b.) Kobe separation; used mostly when the receiving terminal is equipped with grabs. |
Role of Agriculture Canada regarding the carriage of grain | policies governing the production, processing, and marketing of all farm, food, and agri-based products.
grain carriage on ships: the conveyance must be inspected before grain is loaded |
List places where insects or rodents are typically found infested on ship. How is this avoided? | a. wooden structures (limber boards, tank tops, etc)
b) Ventilators, ventilation shafts and trunk ways
c) Casings, guards: pipe, electrical, hydraulic, etc.
d) Corners of holds
this can be avoided by washing or fumigating the hold |
What dangers are associated with using fumigants in cargo holds? | 1. toxicity
-safety of crew at risk; close hatch covers, ventilators, etc. (gas tight)
2. heat
-combustion can occur and cause fire
3. flammability
-rapid build up/high conc. of phosphine gas = explosion |
What information regarding grain stability and grain loading should be supplied to the ship? (hint: grain loading manual) | a. ship’s particulars
b. lightship displacement and KG
c. table of free surface correction
d. capacities and centre of gravity
e. curve or table of angle of flooding, hydrostatic properties, volumes, max heeling moments, stability
f. details of scantlings and fittings
g. loading instructions |
Is this correct? What method of grain cargo securing is this? | Yes!
wire mesh strapping |
What do figures (a) and (b) represent? | a. filled compartment, untrimmed
b. filled compartment, trimmed |
What is this doohickey?
What does it do? | a trimming machine
it levels grain cargo within the hold |
In Part 1 division 3 of the CFTR’s, the Canadian requirements for grain loading, what should a vessel have onboard when taking a load of grain? | 1. a 4 gas detector
2. a cargo declaration supplied by the shipper
3. certificate of readiness
-includes type of grain, holds used, trim required, stowage factor
4. vessel is in fit condition |
Section 125 of Part 1, Division 3 gives the limits on the inland waters, where some relaxations of the grain code requirement applies. What are these limits? | a) Vessel within local forces limits
b) Maximum filled hold possible
c) Partly filled hold; cargo leveled athwartships
d) Longitudinal stress within limits
e) GM within limits of table 10 in stab. form
f) Vessel does not proceed in adverse weather |
What type of bulk cargo separation is this? | Kobe separation |
What type of bulk cargo separation is this? | Tarpaulin separation |
What is wrong with this picture? | cargo residue of cement sticking to hold sides |
How are loose rusts and paint flakes removed?
How are previous cargo stains removed? | 1. a sharp hand scraper
2. cleaning chemicals or air pressure |
