Ballast Water Management
Reasons for managing Ballast Water
“To prevent the translocation of aquatic
species across bio-geographical boundaries »
The problem is not new:
Some National Authorities are already requesting BWM for ships entering
their ports (USA, Canada, Brazil, EU, Australia, Chile)
The IMO have been discussing this issue and worked toward a
Convention for more than 10 years

Ballast Water Management
Definitions
Ballast Water : water with its suspended matter taken on board a ship to
control trim, list, draught, stability or stresses of the ship.
Ballast Water Management : mechanical, physical, chemical and
biological processes – either singularly or in combination – to remove,
render harmless, or avoid the uptake or discharge of harmful aquatic
organisms and pathogens within ballast water and sediments.
Sediments : matter settled out of Ballast Water within a ship.
Ballast Water Capacity : the total volumetric capacity of any tanks,
spaces or compartments on a ship used for carrying, loading or
discharging Ballast Water

9. 9
Ballast Water Management
The requirements
► The Convention applies to all ships designed or constructed to carry
ballast water
 when engaged in international voyages;
 including submersibles, floating craft, floating platforms, FSUs and
FPSOs
► Ships of 400 GT and above are subject to surveys and certification
► All ships subject to the Convention will be required to:
 Carry out ballast water and sediment management
on all voyages
 Have on board an approved ballast water
management plan and a ballast water record book

Schedule for
implementation
Implementation dates as
modified by the 25th
Assembly
A ship constructed in or
after 2009 with a Ballast
Water Capacity of less
than 5,000 m3 will not be
required to comply with
regulation
D-2 until its second

D-1 Standard
Ballast Water Exchange
 Goal: volumetric exchange of ballast water up to 95% of the Ballast Water
Capacity.
 Do not require any modification to the ship’s
existing equipment
Methods:
 Flow through method: pumping to overflow
 Dilution method: ballasts filled through the top allowing
discharge from the bottom
 Sequential: each ballast is emptied and refilled

Ballast Water Exchange
Disadvantages:
Its implementation gives rise to a
number of practical problems
 The operation is laborious
 The sequence may endanger
the strength of the structure.
 Needs favourable sea and
swell conditions,…
Safety of the ship is paramount

BWMS making use of Active Substances shall be granted a specific
approval by IMO Marine Environment Protection Committee.
The procedure described in the IMO guidelines (G9) is a two-step
approach:
 Basic Approval that may be granted on the sole basis of lab scale data.
 Final Approval that may be granted provided that full-scale experiments
The GESAMP-BWWG* evaluates the application according to (G9) and
reports its conclusions and recommendations to IMO-MEPC.

31. 31
Ballast Water Management
Survey – Main points to be checked
Renewal survey
Sediment deposits in a ship’s double bottom
mainly in the hopper side tank section where
the water column is deepest and thus
accumulation greatest.
Sediment collects on the bottom and bilge
shell outboard of bottom internals and
particularly if drainage is poor, Once allowed
to accumulate it congeals and stratifies.

32. 32
Ballast Water Management
Survey – detainable deficiencies
 Absence of a IBWM Certificate;
 Absence of a BW Management Plan;
 Absence of a BW Record Book;
 The vessel or its equipment does not correspond with the particulars of
the IBWM Certificate;
 The designated personnel are not familiar with essential shipboard
procedures
