Question 1 of 15
Is this statement true or false? 'While MARPOL regulations may allow for more relaxed discharge criteria for some of these substances, there is a general consensus that polar waters (and especially the Antarctic waters below 60° South) should remain as "carry in and carry out" for all polluting substances.'
Correct - This statement is true. While MARPOL regulations may allow for more relaxed discharge criteria for some of these substances, there is a general consensus that polar waters (and especially the Antarctic waters below 60° South) should remain as "carry in and carry out" for all polluting substances.
Incorrect - You should review the Precautions when Transiting MARPOL Special Areas or PSSAs section.
Question 2 of 15
Who issues the certificate reflecting the "ice-class" features on a specific vessel?
Correct - The "ice-class" features allow for greater survivability and flexibility in navigating frozen waters and will be reflected in the vessel's certification from the Classification Society she is registered with.
Incorrect - You should review the Polar Class Ships section.
Question 3 of 15
Is this statement true or false? 'Any essential equipment or system which is deemed required to ensure the safe operation of the specific ship, or any systems provided onboard for preventing pollution, should be provided with a single heating system.'
Correct - This statement is false. Any essential equipment or system which is deemed required to ensure the safe operation of the specific ship or any systems provided onboard for preventing pollution, if located in spaces that might be subject to the extreme temperature outside, should be provided with an independent heating system in the case of failure of the primary heating system.
Incorrect - You should review the Propulsion and Steering Systems used in Polar Waters section.
Question 4 of 15
Is this statement true or false? 'Ballast water systems may be fitted with some heating arrangement to ensure that the water does not freeze and cause damage to the ship. However, cycling the ballast water may be acceptable to meet the classification requirements for operating in polar waters.'
Correct- This statement is true. Ballast water systems may be fitted with some heating arrangement to ensure that the water does not freeze and cause damage to the ship. However, cycling the ballast water may be acceptable to meet the classification requirements for operating in polar waters.
Incorrect - You should review the Adverse Effects of Cold Climates on Ship's Cargo and Ballast Systems section.
Question 5 of 15
For how long may oil pollution impact a marine ecosystem?
Correct - Oil pollution may impact a marine ecosystem for 50 years or more.
Incorrect - You should review the Precautions when Transiting MARPOL Special Areas or PSSAs section.
Question 6 of 15
Why are CPP-type propellers usually found on polar-classed vessels?
Correct - CPP-type propellers are usually found on polar-classed vessels because they are continuously turning even when the vessel is stopped in the water.
Incorrect - You should review the Propulsion and Steering Systems used in Polar Waters section.
Question 7 of 15
'Polar Class 1 (PC1) is the lowest level of classification and has the smallest window of operation in polar waters.' Is this statement true or false?
Correct - This statement is false. Polar Class 1 (PC1) is the highest level of classification and has the most open window of operation in polar waters.
Incorrect - You should review the Polar Class Ships section.
Question 8 of 15
Where can the information with regards to Areas to Be Avoided (ATBAs) be found?
Correct - Areas to be avoided (ATBAs) are published for Arctic and Antarctic waters and these should be noted and duly avoided. More information on ATBAs can be found in IMO SN.1/Circ.331.
Incorrect - You should review the Precautions when Transiting MARPOL Special Areas or PSSAs section.
Question 9 of 15
Which of the following is not found on the hull of an Ice-Class ship?
Correct - No hull protrusions, such as fin stabilisers, that would become damaged from striking ice
Incorrect - You should review the Design and Strength of Vessels section.
Question 10 of 15
What main advantage does an azimuth drive have over a conventional propeller drive in polar waters?
Correct - Azimuth drive has no rudder which means fewer components that may be damaged by ice.
Incorrect - You should review the Propulsion and Steering Systems used in Polar Waters section.
Question 11 of 15
Where are polluting emissions defined?
Correct - Polluting emissions are all defined under Annex VI of MARPOL.
Incorrect - You should review the Precautions when Transiting MARPOL Special Areas or PSSAs section.
Question 12 of 15
Is this statement true or false? 'Double bottoms over the entire breadth and length between the forepeak and afterpeak bulkheads must be available on all polar class ships.'
Correct - This statement is true. Double bottoms over the entire breadth and length between the forepeak and afterpeak bulkheads must be available on all polar class ships.
Incorrect - You should review the Polar Class Ships section.
Question 13 of 15
Which of the following is important to be checked before entering polar areas?
Correct - Important checks before entering polar waters may include but not be limited to; draining of the freshwater lines on deck, draining of the fire main, greasing and lubricating all exposed machinery, purging airlines and checking for condensation.
Incorrect - You should review the Preparation Prior to Entry in Polar Waters section.
Question 14 of 15
What may occur in polar waters due to icing on the superstructure?
Correct - Accretion of ice may lead to a reduction of positive stability and a dangerous condition.
Incorrect - You should review the Preparation Prior to Entry in Polar Waters section.
Question 15 of 15
'Polar Class 7 (PC7) is the lowest level of classification and has the smallest window of operation in polar waters.' Is this statement true or false?
Correct - This statement is true. Polar Class 7 (PC7) is the lowest level of classification and has the smallest window of operation in polar waters.
Incorrect - You should review the Polar Class Ships section.
