Answer : A. Categories of Noxious liquid substance;
For the purpose of the regulation of this annex. Noxious Liquid Substances (NLS) may be divided into four categories as follows:
For the purpose of the regulation of this annex. Noxious Liquid Substances (NLS) may be divided into four categories as follows:
Category
X: NLS which, if discharged into the sea from tank cleaning or
deballasting operations, are deemed to present a major hazard either
marine resources or human health and, therefore, justify the prohibition
of the discharge into the marine environment.
Category
Y: NLS which, if discharged into the sea from tank cleaning or
deballasting operations are deemed to present a hazard to either marine
resources or human health or cause harm to amenities or other legitimate
uses of the sea and therefore justify a limitation on the quality and
quantity of the discharge into the marine environment.
Category Z: NLS which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a minor hazard to either marine resources or human health and therefore justify less stringent restrictions on the quality and quantity of the discharge into the marine environment.
Other substances: Substances indicated as OS (other Substances) in the pollution category column of chapter 18 of the International Bulk Chemical Code which have been evaluated and found to fall outside category X. Y or Z as defined In regulation 6.1 of this Annex because they are, at Present, considered to present no harm to marine resources, human health, amenities or other legitimate uses of the sea when discharged into the sea from tank cleaning or deballasting operations. The discharge of bilge or ballast water or other residues or mixtures containing only substances referred to as "other substances" shall not be subject to any requirements of the Annex.

C. Double hull tanker;
For prevention of pollution from oil tankers double hull and double bottom requirements have been introduced. For the purpose of this regulation oil tankers are divided into:
(1) Category 1: Oil tanker means an oil tanker of 20000 tonnes DWT and above carrying crude oil, fuel oil, heavy diesel oil or lubricating oil as cargo and of 30000 tonnes from oil tankers delivered after 1st June 1982.
(2) Category 2: Oil tanker means-which complies with the requirement for oil tankers delivered after In July 1982.
(3) Category 3: Oil tankers mean an oil tanker of 5000. tonnes DWT and above but less than the specified in 1 and 2.
The regulation 20 of annex is applicable to tanker delivered before 6th July 1996. An oil tanker to which this regulation applies shall comply with the regulation not later than 5th April 2005 or than anniversary of the date of delivery of the ship or in the year specified in the table.

| Category-1 | 5th April 2005 for ships delivered on 5th April 1982 or earlier. 2005 for ships delivered after 5th April 1982. |
| Category-2&3 | 5th April 2005 for ships delivered on 5th April 1977 or earlier. 2005 for ships delivered after 5th April 1977, but before 1st Jan 1978. 2006 for ships delivered in 1979-1979. 2007 for ships delivered in 1980-1981 2008 for ships delivered in 1982 2009 for ships delivered in 1983 2010 for ships delivered in 1984 or later |
The
administration may allow category 2 and 3 tankers beyond the
above-mentioned date if satisfactory result of the Condition Assessment
Scheme (CAS) warrants that but the operation shall not go beyond the
anniversary of date of delivery of the ship in 2015 on the date on which
the ship reaches 25 years after the date of delivery, whichever is
earlier date.
Regulation 19 of Annexure I require all tankers of 5000 tonnes DWT and above delivered after 6th July, 1996 to be fitted with double hull separated by space up to 2m but not less than 1m. For tankers below 5000 tonnes DWT the space must be at least 0.76m. Other method of design and construction may be accepted if they confirm to MEPC guidelines.

D. Water Ingress Detection And Alarm System in Bulk Carriers;
- SOLAS chapter 12, Regulation 12, Hold, ballast and dry space water ingress alarms
- Applies to bulk carriers regardless of their date of construction.
- Bulk carriers shall be fitted with water level detectors:
1. In each cargo hold, giving audible and visual alarms, one when the water level above the inner bottom in any hold reaches a height of 0.5 m and another at a height not less than 15% of the depth of the cargo hold but not more than 2 m.
- The water level detectors shall be fitted In the aft end of the cargo holds. For cargo holds which are used for water ballast, an alarm overriding device may be installed. The visual alarms shall clearly discriminate between the two different water levels detected in each hold;
2. In any ballast tank forward of the collision bulkhead alarm shall be giving an audible and visual alarm when the liquid in the tank reaches a level not exceeding 10% of the tank capacity. An alarm overriding device may be installed to be activated when the tank is in use.
3. in any dry or void space other than a chain cable locker, any part of which extends forward of the foremost cargo hold, giving an audible and visual alarm at a water level of 0.1 m above the deck. 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.
-The audible and visual alarms shall be located on the navigation bridge.
- Bulk carriers constructed before 1 July 2004 shall comply with the requirements of this regulation not later than the date of the annual, Intermediate or renewal survey of the ship to be carried after 1 Iuly 2004. whichever comes first.
