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

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


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

10


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 annual survey, but no later than 31 December 2011. (Res A 1005(25)) 2009 2012 2014 2016

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

13


D-1 Standard

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

Less than 10 viable organisms / ml that are less than 50 µm in minimum dimension that are greater than or equal to 10 µm in minimum dimension; and

Discharge of the indicator microbes must not exceed the specified concentrations.

Method:

Use of ballast treatment systems

Example of Ballast Treatment Systems

Physical solid-liquid separation Surface filtration Cyclonic Separation Floculation/Coagulation

Desinfection Ozone sterilisation Chlorination Ultraviolet Thermal devices Add Biocides

And any combination of the above

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.

Verifying that the results of the analysis show compliance with the performance standard of regulation D-2

If applicable, confirming, if necessary by simulated test or equivalent, the satisfactory operation of the ballast water management systems

31



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


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

To ballast water management procedures have been implemented on board.
