waste water accumulated in the
E/R bilge holding tank(s) of the
vessel, before discharging it to the
sea
Under MARPOL - IMO Resolution
MEPC.107(49), discharged water
has to contain less than
15 parts per million (ppm) of oil

Oily Water Separator (OWS)
The OWS must be:
capable of handling any oily mixtures from the machinery space bilges
effective over the complete range of oils which might be carried on board
capable of handling satisfactorily oil of very high relative density or with
emulsified mixtures

Discussion How can we ensure that there is no method to discharge bilges overboard by
by-passing the OWS?
By using Environmental Seals in:
Piping connections, fittings, the OCM, and other control equipment of the OWS
System crossover and connection valves where bilge systems tie into ballast, general
service and other pumping or ejector systems, and systems capable of bilge removal
without the use of the OWS
Every blank or potentially removable flange associated with any piping leading
overboard, such as but not limited to the following piping: bilge, sewage, grey water,
boiler blow down, cooling water, etc.
Any overboard valves connected to ejectors situated in compartments such as but not
limited to steering gear, bow/stern thrusters, and compartments such as the Bosun
store forward, pump rooms etc.
Sludge and dirty oil tanks manholes in engine room spaces and all attached level,
temperature and other removable accessories fitted to them as far as practically
possible
Portable pumps and flexible hoses
By allowing specific personnel to discharge bilges and supervise them
By enforcing the company’s environmental policy
By familiarizing the personnel with the consequences of the violations of MARPOL Annex I

measuring, indicating and continuously detecting the oil content in
water
flag administration
Must be approved by the……………………………..
parts per million (ppm)
The content of oil is measured in………………………………………
Records of the date and time of the total quantity discharged,
of the oil content and the rate of discharge shall be kept
at least 3 years
for………………………………………
OWS and OCM to be maintained and operated as
manufacturer’s instructions
per…………………………………………….
If OWS or OCM fails, no discharge overboard is allowed until the
defect is rectified and flag dispensation is closed out.

19.

OCM Calibration
The OCM must be calibrated at intervals not exceeding 5 years after its
commissioning, or as specified in the manufacturer's instructions, whichever
is shorter as required by MEPC.285 (70) and Company’s instructions
Calibration certificates are issued every 5 years by an approved contractor
ashore and must be:
maintained on board
maintained ashore by the Technical Department
When a new calibrated and certified Measuring cell for the OCM is installed
on board by the vessels C/E or Service Engineers, details along with
the name of service engineer must be recorded in the ORB (Part-I, Code I) &
PMS (Refer to MSOPR-11.3)

Example of how an OWS with absorber works
1. Rough separation: An eccentric spiral pump
draws the mixture out of the bilge
2. Fine separation: A very open porous coalescer
causes, due to its oleophilic surface, fine
separation of even the smallest oil drops
3. The OCM takes samples and controls the use of
the absorber
4. Absorber bypass: If the OCM detects less than
14ppm the operation is done without the
absorber and cleaned water is guided outboards
5. Operation with absorber: If the OCM detects
more than 14ppm the water passes through the
absorber
• if after the extra cleaning the new
measurement < 15ppm, the cleaned water is
guided outboards
• if the OCM shows > 15ppm, the cleaned water
is guided back to the bilge water tank

Sewage Discharge
According to some National Requirements, the discharge of treated sewage is not allowed when the
ship is in their ports or within their territorial waters
In this case, National and Local regulations shall be followed, superseding MARPOL Annex IV restrictions
For example, in the United States, specific waters are designated as "no
discharge zones" where treated and untreated sewage discharges are
prohibited in these areas and vessel discharges are regulated through
the Environmental Protection Agency's Clean Water Act (CWA) National
Pollutant Discharge Elimination System (NPDES) Program
For example, China issued the “Discharge standard for water pollutants
from ships” that controls the requirements for the discharge of treated
sewage

NOx Emissions
Which vessels have to comply with the NOx regulation ?
Ozone production from NOx pollutants: Oxygen atoms freed from nitrogen dioxide by
the action of sunlight attack oxygen molecules to make ozone. Nitric oxide can
combine with ozone to reform nitrogen dioxide, and the cycle repeats
All vessels with diesel engines installed onboard on or after 1/1/2000 with power
output more than 130kw have to comply with the NOx regulation
This regulation applies also on older engines, installed onboard prior to 1/1/2000 but
which undergo a conversion of engine systems & components that affect the
engines NOx emissions, or increase the engine MCR more than 10% after this date
Requirements do not apply to engines installed on board and used solely in case of
an emergency (i.e. emergency generator, lifeboat engines, etc.)

Reduction of SOx emissions
Ensure that vessels operations will fully comply with the
MARPOL Annex VI requirements regarding SOx emissions,
both inside and outside SOx Emission Control Areas (ECAs)
The fuel oil received and consumed must satisfy the Annex VI
maximum Sulphur content limit
The C/E should ensure this by verifying that the Sulphur
content is written on the Bunker Delivery Note (BDN), and
that it is not above the limit stated
In the situation that the BDN shows compliant fuel, but test
results of the “commercial sample” indicates non-compliance,
the TSI has to be notified immediately.

Fuel oil samples under MARPOL
There are three defined fuel oil samples under MARPOL, each provided with a set of IMO
guidelines:
MARPOL delivered sample – the traditional sample taken during bunkering, accompanying
the Bunker Delivery Note (BDN) which represents the fuel oil delivered on board.
In-use sample – represents the fuel oil in use on the ship.
On board sample – represents the fuel oil intended to be used or carried for use on board
the ship.
The “commercial sample” is not required by MARPOL

General Practice for Change-over Procedures – (MSOPR-02.2)
What is the General Practice for Change-over Procedures ?
Calculate the required time for safe change over of fuels
Start at calculated time prior to entering the ECA, to ensure that upon crossing the ECA
border the fuel oil system of the M/E and/or D/G has been fully flushed with the low
sulphur fuel
The less the segregation of the 2 fuel oil systems between the tanks the greater will be the
time interval required for the change over
The time required for fully flushing the fuel system depends upon several parameters,
which are mentioned below:
The existence of separate service and settling tanks
The volume of the service and settling tank, in case these are common for the two fuel
types
The existence of separate purifiers, heaters, etc. for the two fuel types
Requirements for gradual adjustments of the F.O. temperature and viscosity, if applicable

Exhaust Gas Cleaning System (EGCS) - Scrubber
Marine scrubbers generally use sea water to remove sulphur oxides and particulate matter from the
exhaust gas.
EGCS can be used both inside and outside of ECAs.
Vessels fitted with EGCS are permitted to carry fuel oil with sulphur content exceeding that required
by MARPOL Annex VI Regulation 14.
Discharges of EGCS wash water to sea must be continuously monitored.
Several ports and regions limit or ban discharging of wash water into their waters.
Some coastal states (i.e. Australia and USA) require analytical monitoring of wash water.
Residues generated by EGCS should not be incinerated or discharged into the sea but delivered to
adequate shore reception facilities.
EGCS Malfunction
In case of EGCS malfunction (e.g. an alarm is triggered), immediate action should be taken to identify
and rectify the fault.
In case of EGCS breakdown, if the EGCS cannot be put back into a compliant condition within one hour
the vessel should switch over to compliant fuel.

Energy Efficiency Design Index
EEDI is the theoretical indicator for vessel’s Energy Efficiency
Building contract placed on/after 1 January 2013
In the absence of contract, keel laid after 1 July 2013 or the delivery of
which is on/after 1 July 2015
NOT applicable to vessels sailing entirely within flag state waters
The EEDI sets CO2 emissions reference and is calculated once for each
vessel. It is a reference value for the energy efficiency indicating how
many grams of CO2 a vessel emits for the transportation of 1 tonne of
cargo over a distance of one nautical mile
The EEDI dimension is given as: gr CO2 ÷ (tonnes x nautical miles)
