What are the basic requirements of MARPOL Annex V

- No discharge of plastics anywhere

- Food scraps processed throug the galley disposal unit (greater than 25mm) cannot be discharged within 3nm

- Discharge permitted, while en route, as far as paractible from the nearest land, but in any case, greater than or equal to 12nm from the nearest land not within a special area.

- On coastal voyages, with short runs between ports, garbage should be retained on board for disposal to shore facilities in port. And stowed correctly in the vessels bins.

- Engineroom waste should be keept seperate to other garbage as it may require disposal at a different location.

What are the basic sections of the garbage management plan?

- Procedures for collecting garbage

- Procedure for processing garbage

- Procedure for storing garbage

- Procedure for disposing of garbage

What is the reference for what can and cant be burnt in incinerators?


Why are incinerators hard to manage?

Due to the specific gravity of different oils

- The saftey of ships and their crews

- Prevention of pollution of the environment by shipping

What does AMSA do?

Authorises certian clasification societies to act on it's behalf in the surveying and certification of ships?

Who does the load line convetion not apply to?

Fishing vessels or vessels less than 24 metres in lenghth.

State the benifits of load line regulations on vessels.

- Increases the range of stability when the ship is rolling

- Helps prevent water coming on board

- Provides a reserve of buoyancy

- Avoids excessive stress on the ships hull due to overloading

What is the purpose of SOLAS?

To ensure the safe operation and conduct of all vessels with the primary emphasis on the safety of life. The contravention sets international guidelines for the construction, equipment, operation, and navigation of sea going vessels.
