Chapter 9

Question 1

Hazards associated with bulk carriers

Answer 1

• Structural damage due to improper cargo distribution, loading/unloading equipment, or cargo properties
• Loss or reduction of stability during a voyage, due to cargo shift
• Chemical reactions of cargoes, creating hazards for the crew
  and damage to the vessel

Question 2

What is solid bulk cargo

Answer 2

any cargo, other than liquid
or gas, consisting of a combination of particles, granules or any larger pieces of material generally uniform in composition, which is loaded directly into the cargo spaces of a ship without any intermediate form of containment.

Question 3

What does the loading manual contain

Answer 3

.1 Stability data

.2 Ballasting and deballasting rates and capacities;

.3 Maximum allowable load per unit surface area of the tank top plating;

.4 Maximum allowable load per hold;

.5 General loading and unloading instructions with regard to the strength of the ship’s structure
including any limitations on the most adverse operating conditions during loading, unloading,
ballasting operations and the voyage;

.6 Any special restrictions such as limitations on the most adverse operating conditions imposed
by the Administration or organization recognized by it, if applicable; and

.7 Where strength calculations are required, maximum permissible forces and moments on the
ship’s hull during loading, unloading and the voyage.

Question 4

Prior to loading bulk cargo on bulk carriers of 150m in length and upwards, the shipper shall declare, what?

Answer 4

the density of the cargo, in addition to providing the cargo
information required by regulation VI/2.

Question 5

What does bulk density mean

Answer 5

the weight of solids, air and water
per unit volume. Bulk density is expressed in kilograms
per cubic metre (kg/m3), in general. The void spaces in the cargo may be filled with air and water.

Question 6

Bulk carriers of 150 m in length and upwards shall be fitted with a

Answer 6

loading instrument capable of providing information on hull girder shear forces and bending
moments, taking into account the recommendation adopted by the Organization.

Question 7

Bulk carriers shall be fitted with water level detectors:
where?

Answer 7

In each cargo hold, giving audible and visual alarms,
(one at 0.5m and one at 15percent of the depth of
the hold but not more than 2m). If tank is used as
ballast then alarm overrides may be installed
* In any ballast tank forward of the collision bulkhead
* In any dry or void space other than a chain cable
locker. Such alarms need not be provided in enclosed
spaces the volume of which does not exceed 0.1% of
the ship’s maximum displacement volume

Question 8

What does IMSBC stand for

Answer 8

International
Maritime
Solid Bulk
Cargoes Code

Question 9

The primary aim of the International Maritime
Solid Bulk Cargoes Code (IMSBC Code),

Answer 9

is to facilitate the safe stowage and shipment of solid bulk cargoes by:
* Highlighting dangers
* Giving guidance on procedures

Question 10

Considerations for safety onboard

Answer 10

• Prior to and during loading, carriage and discharge of a solid bulk cargo, all necessary safety precautions shall be observed.
• A copy of the instructions on emergency response and medical first aid relevant to incidents involving dangerous goods in solid form in bulk shall be on board.

Question 11

health concerns in bulk carriers

Answer 11

Poisoning, corrosive and asphyxiation hazards > Oxidation may result in oxygen depletion, emission of toxic gases or fumes and self-heating. There are also cargoes which, when wetted, are corrosive to skin, eyes and mucous membranes or to the ship’s structure.

• Health hazards due to dust > Proper PPE should be worn, potential protective skin creams and washing all clothes properly to avoid acute and chronic issues.
• Flammable atmosphere > Explosive dust, flammable gas.
• Ventilation > preventing gasses building, preventing gases entering
  accommodation/crew spaces, being wary of introducing O2 into the cargo
