SeaCURE BALLAST WATER MANAGEMENT SYSTEMS COMPLIANCE ASSURED, WHEREVER YOU ARE.

SeaCURE SYSTEMS, FOR THE LIFETIME OF YOUR VESSEL. SeaCURE systems Evoqua s maritime solution, the SeaCURE ballast water management system (BWMS), enables ship owners and operators to safely comply with the stringent regulations set by the International Maritime Organisation (IMO) and the US Coast Guard (USCG). Electrochlorination at the heart of the system Proven Chloropac cells are at the heart of the system, generating sodium hypochlorite on demand, using ambient seawater. This method has been used for many years to prevent marine growth in seawater piping and heat transfer systems of land-based, offshore and shipboard installations. After-sales care and support We know that compliance doesn t end with the purchase and installation of a system. That s why we support our customers with a comprehensive range of services designed for the entire product life cycle, including lifecycle maintenance and after-sales care. Partner network To help operators through of the compliance process, we ve built a global network of partners. This will guarantee our customers assistance with scoping and planning through the use of 3D scanning surveys, and help with installation and commissioning at a series of locations worldwide. Quick response support and maintenance to ensure continuous vessel compliance can be provided for all customers as a standard service.

SeaCURE SYSTEM A PROVEN SOLUTION CURRENT APPROVALS SeaCURE BWMS is designed to operate in fresh, brackish and sea water at a wide temperature range. Its performance has been rigorously tested and proven by third parties, in addition to receiving type approval by the IMO and BSH, the Federal Maritime and Hydrographic Agency of Germany (Bundesamt für Seeschifffahrt und Hydrographie). SeaCURE BWMS has already achieved alternate management systems (AMS) acceptance for fresh, brackish and full saline water, as granted by USCG.

Universal Configuration Irrespective of capacity required (500-6,000m³/hr) the system is exactly the same physical size and configuration, with only the cell type changing to accommodate higher capacities.

FILTRATION: AN IMPORTANT STAGE IN BALLAST WATER MANAGEMENT Removing zooplankton (particularly hard shelled organisms) by chemical means can require very high doses or long exposure times. High concentrations of biocide can encourage corrosion. To eliminate this risk, the SeaCURE BWMS employs a filtration system. Filtration at 40 microns ensures larger organisms and sediment are effectively removed during ballasting. A fully automated self-cleaning filter provides reliable non-stop operation at high sediment loads reducing associated tank cleaning cost and allowing for the effective treatment of smaller organisms at lower biocide levels. Surfaces in contact with seawater are often prone to biofouling. The accumulation of marine organisms on filter screens may lead to complete filter clogging and the associated system downtime. To eliminate the risk of biological growth on the filter screens, SeaCURE BWMS employs a proprietary filter protection system where a continuous low dose of Sodium Hypochlorite is injected at the filter inlet when the BWMS is in use. Our patented filter biofouling prevention method was proven to keep filters clear of macro and micro fouling even after 4 years of use in some of the harshest port environments.

THE SeaCURE SYSTEM IS BASED ON THREE PILLARS: Filtration Electrochlorination Demand-monitor control logic THE PROCESS 1. Uptake of ballast water 2. Filtration stage removes larger particles >40 microns 3. Automatic backwashing unit cleans the filter triggered by differential pressure without interrupting the filtration process 4. Small stream of seawater taken to the electrolyzer for electrolysis (when vessel is in fresh water, stored seawater can be used for the electrolyzer) 5. Seawater is processed in electrolyzer (5a) to produce Sodium Hypochlorite. Power is provided by the Transformer/Rectifier (TR) unit (5b) 6. Tank allows any hydrogen produced to be safely separated and dispersed, the sodium hypochlorite biocide is briefly stored prior to reinjection into the ballast flow 7. The dosing module regulates the injection of sodium hypochlorite and adjusts to varying conditions in the ballast water main 8. The chlorinated water then goes to the ballast tanks as specified 9. Upon deballasting the ORP of the water is analysed (9a) in order to initiate neutralisation (9b) as necessary 10. Treated ballast water is discharged safely 1 8 9b

SeaCURE SYSTEM ENHANCES OPERATIONAL EFFICIENCY AND RETURN ON INVESTMENT Proprietary control logic Proprietary control logic of the SeaCURE system monitors the appropriate hypochlorite dose level necessary to provide the required efficacy, while avoiding any detrimental effects on the ship, its crew or the environment. The biocide dosing level is variable, dependent on ballast water conditions physical, chemical, and biological characteristics, called chlorine demand. Evoqua electrochlorination and dual purpose Our approach to electrochlorination is to take a seawater feed stream of less than 1% of the main ballast flow for the process. This gives some considerable advantages in terms of power consumption, ease of installation and the ability to function in a wide variety of operating parameters. This feature is very useful for retrofits where space is limited. Due to the low flow requirement it is possible to use the SeaCURE BWMS as a marine growth prevention system in voyage. Intake treatment The SeaCURE system treats ballast water only during ballasting, allowing the system to be sized for ballast water flows (e.g. for one pump), while deballasting can be done with higher flow rates (several pumps). By utilising this method the SeaCURE system provides reductions in associated power consumption and costs. This is especially suitable for container and bulk carrier ships that use only one pump on intake and two pumps on discharge.

FLEXIBLE SOLUTION TO SUIT YOUR VESSEL Weight and size are of paramount importance when considering a ballast water management system. Evoqua recognizes this and can offer the SeaCURE BWMS in two options; modular and compact. The flexible version allows for the differing units to be fitted into spaces available on the vessel after a 3D scan and engineering check. The compact version allows for the unit to be delivered in a skid mounted option with minimal dimensions for an electrochlorination system. This can then simply be inserted on a vessel and the system easily plumbed into the ballast lines. COMPACT DESIGN Compact sized for when space is at a premium Quicker on site installation (single lift) 2.2m Can be assembled pre-installation to save time Standardised range for quicker logistics and simpler handling Can be installed as one skid Easy installation: possible to install on voyage rather than valuable dry-dock time Designed to fit through standard vessel hatchways 500-6000m3/hr same skid size irrespective of capacity 2m Compact SeaCURE System 1.45m
