REGULATIONS FOR THE PREVENTION OF POLLUTION BY OIL
1.0 DEFINITIONS :
1 OIL : means petroleum in any form including crude oil, fuel oil, sludge, oil refuse and refined products.( A list of such oils is given in Marpol annex 1)
Note: Animal and Vegetable oil Fall under NLS Annex 2)
Oil Rags are to be treated under Annex 5
2 OILY MIXTURE : means a mixture with any oil content.
3 OIL FUEL : means an oil used as fuel in connection with the propulsions and auxiliary machinery of the ship in which such oil is carried.
4. OIL TANKER : Means a ship constructed or adapted to carry oil in bulk in its cargo spaces.(Note FPSO and FSU are NOT OIL TANKERS and are not to be used for transport of oil except by agreement by flag state and relevant coastal state on a VOYAGE BASIS and under RARE circumstances(FPSO =Floating ,Production , Storage and Offloading Facilities.)(FSU=Floating storage Units)
5 CRUDE OIL : Hydrocarbon Mixture, occurring naturally in the earth, whether treated or not to facilitate transportation, even if a certain distillate fraction has been added to or removed from it.
6 SEGREGATED BALLAST : Means ballast introduced into a tank which is completely separated from cargo and fuel system. Nevertheless, Emergency discharge of segregated ballast may be carried out by providing a connection to the cargo pump via a portable spool piece. Non – return valves should be fitted to prevent passage of oil to SBT.
7 CLEAN BALLAST : Means ballast in an oil tank, which has been so cleaned prior to ballasting, that when the ballast is discharged from a stationary ship, into calm waters, on a clear day it will not leave traces of oil on the surface of water. If the same ballast is discharged through ODMCS and it shows that the oil content <15 PPM, then the ballast is said to be clean notwithstanding the presence of visible traces of oil the surface of water.
8 NEAREST LAND : Is the distance from land measured from the base line from which the territorial sea of a state is measured as per international law.
9 INSTANTANEOUS RATE OF DISCHARGE OF OIL CONTENTS: Means rate of discharge of oil per hour at any instant divided by the speed of the ship in knots at the same instant.
10 SLOP TANK : Means a tank specifically designed for the collection of tank draining, tank washings and other oily mixtures.
11 COMBINATION CARRIERS : Ships designed to carry oil or solid bulk cargoes.
12 WING TANK : Tanks adjacent to shell plating
13 CENTRE TANK : Tank located inboard of a longitudinal bulkhead
2.0 Annex I applies to all ships to which MARPOL 73/78 applies. The discharge of oil into the sea is prohibited in some areas and severely restricted in others. Ships are required to meet certain equipment and constructional standards and to maintain an Oil Record Book. With the exception of small ships, a survey is required and, for ships trading internationally, certification in prescribed form in necessary. Ports are required to provide adequate reception facilities for oily mixtures and residues to meet the needs of ships using the ports. As per SOLAS resolution, all ships carrying ANNEX 1 materials are to be provided by MSDS (SAFETY DATA SHEETS) prior to loading cargo.

2.2 Exceptions to the above discharge controls are as follows: It does not apply to
1. The discharge into the sea of oil or oily mixture necessary for the purpose of securing safety of the ship or saving life at sea;
2. The discharge into the sea of oil or oily mixture resulting from damage to a ship or its equipment:
3. All reasonable precautions have been taken after the occurrence of the damage or discovery of the discharge for the purpose of preventing or minimizing the discharge.
4. This exception will not apply if the owner or the master acted either with intent to cause damage or recklessly and with knowledge that damage would probably result.
3.0 Ballasting Arrangements for tankers :
1) a) Oil tankers between 600 dwt and 5,000 dwt : to provided with double bottom tanks with height not less then 0.76m.
b) Oil tankers of 5,000 dwt and above : to be provided with double hull .
c) Oil tankers of 20,000 dwt and above in addition to above are required to comply with bottom raking damage survivability criteria.
2) In tanker > 5000 DWT, segregated ballast shall be carried in tanks which shall be constructed and located as follows:
- Wing Tanks:
1) For full cargo tank length.
2) For full depth of tanker and
3) Each SBT of width between 1.0m to 2.0m
- D.B. Tanks :

NOTE: The date for application of double hull for tankers greater than 5000 dwt is from 6/07/96. This means after 6/7/96 all tankers will have double hull and most of the tankers not having double hull will be phased out by 2015 or by the year ship becomes 25 yrs old whichever occurs early. This implies that only a tanker delivered after 1984 may be permitted to operate beyond 2010, up to 2015(subject to CAS) after its delivery. A tanker delivered before 1984 would complete 25yrs before 2010, hence there is no question of granting any extention to it beyond 2010.Flag state shall communicate to IMO if any extention is granted. PSC may deny entry to a tanker which has been granted extention.
4) Regulations exist for following topics : (a) Condition assessment scheme (CAS) to verify history of vessel, its cargo and condition of tank etc. CAS is in addition to Classification approved Enhanced Survey Programme to vessels which are used for thickness measurement and determination of structural strength of spaces. CAS inspections are mandated by the need to make the older tankers be phased out early or make them operational by complying with the DBS/Double Hull requirements in their design etc .CAS is a hull structure survey scheme which focuses on planning diligence and greater transparency in reporting.
- In the Antarctic Area, all ships, irrespective of their DWT/GT shall not carry HGO( Heavy Grade Oil) as cargo or carriage and use as fuel oil of HGO. HGO means any oil having a density greater than 900 kg/m3 at 15 deg C. Such oils include bitumen, tar and their emulsons. Such oils have a large sulphur content in them which cause excessive pollution .In other areas carriage of HGO in single hull ships is not permitted
- For tankers built after 1/1/2007 and > 5000 tons DWT, the Pump Room Spaces shall be provided with Double bottom protection having minimum height 1.0mtrs.
- For tankers to be delivered after 1/1/2010 and more than 5000 tons DWT, provisions exist to limit the mean oil outflow parameter between 0.021 & 0.012m3 of ships total cargo capacity (in m3) at 98% full Volume for protection in event of collision / stranding.
- On existing tankers, the hypothetical outflow in case of damage to side & bottom is calculated as per regulations. Cargo tanks on tankers shall be such that the hypothetical oil outflow is less than 40,000m3 . The capacity of one wing tank shall not exceed 75% of this calculated hypothetical outflow. The volume of any one center tank done not exceed 50000m3 .
- Intact stability criteria, sub-division and damage stability calculations are provided in the regulations.
- Fixed / floating platforms shall comply with the discharge requirements of this Annex as far as reasonable & keep a record of all operations pertaining to oil in a form approved by administration.
- PROTECTIVE LOCATION(PL) means Segregated Ballast Tanks are selectively located along the shipside to give optimum protection to crew and cargo in case of grounding or collision so that in eventuality of accident ,it is water that is spilt and not oil.
5) Ballast in Cargo Tanks:On tankers fitted with SBT, ballast can be only carried in cargo tanks only under the following circumstances:
1. On those rare voyages when weather conditions are so severe that, in the opinion of the Master, it is necessary to carry additional ballast water in cargo tanks for the safety of the ship.
2. When tankers are required to pass under low bridge
3. When local port or canal regulations require specific draughts for safe navigation.
4. On crude oil tankers, the additional ballast so carried (as per 1,2,3) shall
be carried in cargo tanks only if such tanks have been crude oil washed
before departure from oil unloading port or terminal. The resulting ballast is to be considered dirty ballast and discharged as per discharge criteria (ODMCS is provided; tank cleanings and slop tank arrangements are provided etc)
7) Ballast In Fuel Oil Tanks : New ships of 4000 G.T and above and new oil tankers of 150 G.T and above, ballast water shall not normally be carried in any oil fuel tank
