On February 13, 2004, the International Maritime Organization (IMO) adopted the International Convention for theControl and Management of Ships’ Ballast Water and Sediments, The Convention, introducing a Ballast Water perform-ance standard in order to attack the issue of the spread of harmful aquatic organisms carried by ships' ballast water.

To meet this standard, ballast water treatment is required. The Convention mandates all ships carrying ballast water tomeet the Ballast Water performance standard by the year 2016. This requirement is phased in already as of, 2009.

”The Ballast Water Management Convention will – when entered into force – require all ships, newand existing, to install Ballast Water Treatment (BWT) systems onboard;

- For new ships; from 2012 (ships keel laid after 1 January 2012)- For existing ships; latest on the first intermediate or renewal survey, whichever comes first,

after the anniversary date of delivery of the ship in 2014 or 2016, depending on thedate and ballast water capacity of the ship”.

Compliantfor gashazardousareas

BWM Systems are powered by electricity and are usually installed inexact alignment with the ballast water pipeline. This simply makes itimpossible for many BWM Systems to meet safety requirements andhence Class Approval for installation in pump rooms and other gas hazardous areas.

OceanSaver’s unique design features an “Approval in Principle” for gashazardous areas - issued by DNV - which is incorporated into the TypeApproval. Hence, OceanSaver offer a fully approved solution withoutany limitation to ships that have gas hazardous areas.

OceanSaver’s Core Technology– Activated Water

Decay of OceanSaver’s Anolyte during third party land-based testing forType Approval at NIVA’s test facility, Solbergstrand - Norway.

This unique technology provides a mixture of oxidants with very short half-life characterisedby a very rapid consumption when injected into the ballast water. The process is advantageous

when compared with conventional electrolysis or oxidising disinfectants as it require only a very limiteddosage (the concentration injected in the Ballast Water initially (maximum value), is below 2.5 mg/L).

Typical consumption rates are illustrated in the figure below.

NOChlorination

A small portion of the ballast water, approximately 1,6% is fed to the C2E and used as an electrolyte in the membrane cellwhere the membrane is isolating the electrodes forming “anode chambers” and “cathode chambers” producing “anolyte”and “catholyte” respectively. The anolyte is acidic whilst the catholyte is an alkaline. The anolyte is partially neutralised bymixing with the catholyte to achieve the desired oxidant mix. When this mix is injected into the ballast water, chemicalprocesses will take place creating additional oxidants - oxidizing organic matter present in the ballast water very rapidly.

Due to its reactivity – the oxidants are consumed rapidly during the process of eliminating the unwanted species. Accord-ingly residual oxidant (TRO) is reduced within a few hours to typically below 0,2 mg/L TRO. Neutralisation is a contingencyin the OceanSaver system and rarely required.

Specification ofa ballast water treatment system

Certification• The BWTS should have Final Approval from IMO and Type Approval from flag state• The Type Approval certificate should be issued by the makers own flag administration or entity acting on their behalf

such as a Classification Society• For installation onboard tankers with pump room or submerged ballast pumps, the system must have Ex approval in

principle from Class

Installation• Will there be a pressure loss taking BWTS, pipes and valves etc. into consideration? For retrofit, can

existing ballast pumps be modified or must new pumps be installed? • What is the required footprint, and where will the BWTS be installed? Do you have required space available in

designated area?

When considering installment of a ballast water treatment system on new buildings orexisting vessels, it is essential to specify the system to fulfill all your requirements.

Vessel type, vessel size, trade pattern and the ballast pumpcapacity, are among the factors you have to consider

when specifying a suitable technology.

Operation• If the system requires any consumables during operation, what is the cost, availability and space requirements of these

consumables?• What is the minimum holding time in ballast tanks before de-ballasting can commence? • Is the system requiring treatment prior to discharge (treatment, neutralisation of oxidants etc.) • Can the system be operated in Fresh Water, Sea Water, Low Temperature and High Temperature?• Are any toxic bi-products, gases, hazardous waste etc. produced during operation or maintenance?

Compliance• Is the system compliant to the IMO PSPC (Performance Standard for Protective Coatings)? • Is the system in compliance with General Class requirements?• For systems using electrolysis/electrochlorination technology or ozone, is the levels of oxidants left in ballast water

within recommendations from coating manufacturers to prevent accelerated coating breakdown and limitationson warranty?

• What is the power requirement, during ballasting and de-ballasting? Will specified generators deliver sufficient electricalpower? For retrofits, can existing generators be utilised or do they have to be modified?

• What will be the total installation cost and what is the installation time for a retrofit?

coatings - reduction in TCO

Reduced corrosionThe OceanSaver BWTS has been subject to comprehensive, appropriate tests to ensure that it will not damage ballast tankcoating systems, and has proven that it will not hinder shipowners attempts to meet the requirements of the newly devel-oped and implemented Performance Standard for Protective Coatings (PSPC).

Two full-scale shipboard tests were carried out over a duration of more than 12 months. These were supported by a 6month laboratory test. All tests were undertaken independently by corrosion engineers and coating systems experts atDNV’s Corrosion Laboratories in co-operation with Safinah, a UK coating consultancy firm. Through these tests, theOceanSaver BWTS demonstrated that it would not harm ballast tank coating systems. Even on scratched surfaces with ex-posed steel, the OceanSaver treatment showed significantly decreased creep corrosion. Over the test period, a reduction inthe consumption of anodes of 11-15 per cent was gained when using OceanSaver BWTS.

Compliant with the intentions of the Performance Standard for Protective CoatingsThe PSPC aims to achieve a fifteen year target life for ballast tank coatings. The comprehensive OceanSaver test programconfirms that coatings are protected and thus OceanSaver is strengthening the intention of the PSPC.

OceanSaver BWTS stands out among Ballast Water Treatment Systems for its commitmentto protecting ballast tank coatings, demonstrating its performance and undertaking tests.

Analysis of ballast tank coating assessments with and without treatment by the OceanSaver system -confirming reduced creep corrosion on test panels exposed to treatment.

Over 12 months, real-time, in-situ ballasttank testing has shown the OceanSavertreatment to be fully compatible with awide range of commercial, approvedballast tank coatings.

OceanSaver is also compliant with theintentions of the IMO's PerformanceStandard to improve the durability &performance of ballast tank coatingschemes.

RetrofittingBWTS –The challenge

The installation of a BWTS onboard an existing vesselwill require comprehensive planning. Owners will haveto consider both technical and commercial aspects inaddition to making a schedule for engineering,ordering and installation of the selected system.

Technical aspects to consider; • What kind of system technology is suitable?• Ex approval? • Space requirements?• Ballast pumps modifications? • Electrical interface• Installation during operation of the vessel, during intermediate survey or during dry-docking?• Before detailed planning can commence, the owner has to select his preferred system• Installation of BWTS will require for the first vessels long lead time due to; pre-engineering, planning, detailed

engineering, installation and commissioning.

OceanSaver can provide ownerswho are looking to install BWTSwith extensive support. Initially we will submit a genericdocumentation package for thevessel type / size with the ballastwater pump capacity required.Secondly we offer the owner anonboard assessment. Based onthe onboard survey we will pro-vide a report with installationrecommandations and drawings. With this report in handowners will have a sustain-able technical basis forentering into discussionswith yards for installationof BWTS onboardtheir vessels.
