CHAPTER 1
INTRODUCTION AND OVERVIEW
1-1 INTRODUCTION.
The Elinca system incorporates the most recent developments in the use of the Electrolytic Method for the protection of all types of sea water piping or systems against marine growth, fouling and corrosion. This system is designed specifically for the protection of seawater systems in ships, offshore structures and shore installations. The patented design is the result of a combination of technical design innovation and practical operating experience, which have been brought together to develop a system which is fully automatic, requires little maintenance and is trouble free.
The Elinca System for the protection of seawater systems against the fouling by shell fish, barnacles, growths of algae, etc., achieves a direct saving by reducing operating, replacement and chemical costs.
The Elinca System utilizes the electrolytic method of introducing into seawater low levels of copper/aluminum alloys or iron combinations which have proved highly effective in combating fouling and reducing corrosion. These special anode combinations are generally fitted at the point of entry of the seawater, sometimes with additional booster anodes added downstream from it., i.e., copper and iron anodes fitted in aluminurn/brass condensers. Anodes can also be fitted in strainers or supplied fitted in a suitable anode mounting assembly which can easily be installed into the seawater pipeline.
1-2 OVERVIEW.
The Elinca System has only a small power requirement, usually not exceeding 0.5 kW, and it should not be confused with cathodic protection systems where the power requirements are much greater. It also differs insofar as the Elinca system is actually a process for water treatment whereby the sea water acts as a vehicle for transporting the antifouling and corrosion agents to the areas requiring treatment.
During electrolysis, ionic products from the dissolving anodes combine to create an environment hostile to the primary forms of marine growth. Corrosion is also reduced. The sea water moving past the anodes into the systembeing protected acts as a mixing agent in addition to its transporting function. The aluminum hydroxide formed flocculates the released copper. This copper- aluminum hydroxide floc is carried through the system and, being highly gelatinous, tends to spread out into the slower moving areas where marine growth larvae are most likely to settle. This process is continuous and cumulative throughout the system, although, in fact the amounts of copper and iron being released are small -less than 2 parts per billion (2 PPB) each. The cupro-aluminum film thus builds up to create a thin, non-heat - insulating protective coating throughout the system being treated.
1-2-1 SYSTEM SPECIFICATION. The Elinca systemuses speciallydesigned "sacrificial Anodes" and a special control systemto apply and control regulated direct current (DC) to them. The rate of sacrifice (and the dose applied) is dependent on the flow rate through the system and the amount of current sent to the anodes. Figure 1-1 shows a typical anode system set up. Table 1-1 gives the specification for your unit.

CHAPTER 2
GENERAL DESCRIPTION/TECHNICALDESCRIPTION OF SYSTEM
2-1 GENERAL DESCRIPTION.
The system works on the principal of the use of impressed current sacrificial anodes. The design life of the anodes is calculated by analysis of the relevant parameters, such as volume to be treated, accessibility (system shutdown, dry docking schedule, maintenance schedule, etc.) These factors determine the size and number of anodes to be used and the strength of the electrical current required.
System hardware comprises a control panel incorporating anode monitoring and control instrumentation, and specially alloyed anodes which are positioned upstream from the area to be protected. The main power source is converted to low voltage D.C., and is passed through the control circuit and instrumentation in the control panel to the anodes. This involves very low power consumption from the ship being treated, less than O.5kW. The anodes are generally of two types, mounted either individually or, in the case of some smaller installations, in a single assembly.
The anti-fouling anode employed with the Elinca system, is a proprietary development of Parmatic Pollution Control Corporation and is of a specific alloy. It has been found to be extremely effective in the control ofbio-fouling when used alone or in concert with other electrodes.
The corrosion anode may be manufactured from aluminum or iron. Iron anodes are used in systemsusing aluminum-brass or cupro-nickel alloys. The iron compounds released bythese anodes into the coolingwater provide impingement corrosion protection to condenser tubes, in addition to their anti-foulant transport function. This is similar to that provided by aluminum anodes.
The weight of the anodic material will vary from one installation to another, and is determined by two factors. The flow rate in the system and the required anode life. For shipboard installations the anode life is generally designed to coincide with the ship's dry-docking schedule, although in some cases it is possible to replace anodes without the necessity for dry-docking.
2-2 ANODES.
These are basically of two types, known as anti-fouling and anti-corrosion anodes. In the case of the anti-fouling anode the material used is always copper. Its function is the control of marine growth. The anti-corrosion anode is either of two types, aluminum or iron. The aluminum anode produces the highly gelatinous substance' Aluminum Hydroxide' which gathers up minute impurities in the water and also acts as a transporter for the copper.
The iron anode is used mainly to provide beneficial iron compounds into seawater systemswhere aluminum brass is being used. (See Figure 2-1 for basic anode unit) .

3-3 INSTALLATION OF ANODES
As previously stated the anodes are of three types. They are easily identified by the nameplate on the top of the housing assembly:
It is important that each anode is positioned according to its installation requirements. It may be necessary to change the selected position should there be any unforeseen obstruction, but the anodes should be fitted as close to their intended position as possible. Care should be taken not to strip the anode bolt, since the anode assembly is internally sealed against water ingress.
NOTE:
If the sea chest or compartment being treated is Coated with an insulating paint or finish, a cathode must be inserted into the sea chest or compartment.
The cathode must be placed within I' (30.5cm) of its corresponding copper anode.
The assembly procedure for installing each anode is similar, each anode is to be installed in the following manner:
1. Cut out a hole in the top of the sea chest or compartment being treated to suit the anode mounting flange.
Remove all burrs and sharp edges (see Figure 3-2.)
2. Before welding mounting flange in place protect all exposed threads and flange surfaces from weld splatter.
3. Weld the mounting flange in place as shown below. Welds to be continuous and watertight.
4. Repair existing external coating on sea chest with 60 Mils of glass flake epoxy, or to original coating after all welding is completed. Do not coat the interior of the sea chest.

5. Install the supplied 1/8" thick flat gasket onto the mounting flange.
6. Carefully install the anode assembly through the sea chest opening and onto the mounting flange.
Secure in place with the supplied flat washers and lock nuts, Torque to 175ft -lbs (778Nm.)
7. Connect the cable assembly from the control box to the anode.
Note: The cable will be supplied in bulk lengths, and is to be cut to suit at installation. End connectors will be supplied complete with sockets and pins for user installation.
Test all connections for insulation and continuity, remember there should be no electrical continuity or resistance between anodes and surrounding structure until the electrolyte (sea water) is present in the system.
8. Inspect all cables for mechanical damage sustained while fitting out, ensure that cables are protected against vibration and chafe.
9. Ensure that each anode assembly is completely watertight.
NOTE:
No paint, grease, mastic or other substance should Be allowed to touch the uncoated anode surface.
3-4 INSPECTION AND TESTING OF ANODES
During maintenance, all anodes should be checked for anode to sea chest insulation resistance, which should read 40meg ohms or more. The anodes should be checked for moisture penetration and that all connections are sound.

CHAPTER 4
COMMISSIONING AND SYSTEM OPERATION
4-1 COMMISSIONING AND SYSTEM OPERATION.
Normally the commissioning of the system will be checked and supervised by a technician provided by Parmatic or one of its agents. If this option is not provided the following procedure should be followed when installation is completed and the electrolyte (seawater) is in contact with the anodes.
L Switch on each control panel
2. Adjust each current control dial until the ammeter reads I amp::J:10% (at peak of excursion.)
Adjustments can only be obtained by trial and error since the relationship between amps and voltage depends on the total resistance in the circuit. However, the system should not be allowed to fall below 1amp for any length of time -certainly not more than 48 hours -as the system is not functioning efficiently in this event. Should this occur re-adjust the ammeter to 1amp. When anode currents have been set they should remain, more or less constant, for a period of 16months. During this time, known as the "conditioning period", an appreciable amount of anode material will have been passed into solution.
Any special re-adjustments which may be recommended, such as boosting anode current over a short period of time, can be made by means of the current control knob. It is important to return the settings to normal at the correct time or anode wear may be excessive. Anode wear can generally be detected by the gradual falling off of current, an alternate, more accurate, indication is provided by the anode wear detector.
Greater water conductivity will result in an increased current to the anodes and conversely a decrease in temperature or salinity will reduce the current. In some systems this increase or decrease in current will occur automatically over a wide range of fouling conditions.
4-2 SYSTEM OPERATION - FAULT FINDING
Elinca antifouling systems are designed to operate continuously once they have been commissioned. A record should be kept of the initial and stabilized current values of each anode. These should be periodically sent to the manufacturer. If abnormal anode readings occur each anode should be checked according to the table below:

4-3 IN SERVICE ADJUSTMENTS - COPPER ANODES
The efficientworking ofthe Elinca system can onlybe detennined by inspection ofthe seawater enclosure being protected, i.e., examine length of pipe, strainer, heat exchanger, etc. If evidence of fouling occurs the current on the appropriate anode should be increased. But if no fouling is present after 16 months from commissioning, the current can be reduced by 0.1 amps, repeated at 3 month intervals.
4-4 IN SERVICE ADJUSTMENTS - IRON ANODES
The initial adjustments should remain unaltered for the duration of the anode life.
4-5 OPERATING PROCEDURE AND INSPECTION
The Elinca system is designed to give continuous and trouble free protection against marine growth and corrosion with a minimum of maintenance. It will only operat~ for the full planned anode life and give complete protection, if the anode currents are maintained at the recommended settings.
Sincethe current will vary with temperature and salinity it is essential that the current reading is checked daily and adjusted ifvarying by more than 10%. It is recommended that the current readings are logged to give a record of performance which should be sent to the manufacturr for examination.
Insufficient anode current will result in fouling of the water system.
Where treated sea water is used as feed water for evaporators producing drinking water, the electric current to the anodes in the sea water feed is limited by means of current control to a level that will maintain copper concentrations well below that required by the EPA. The relevant anodes are clearly marked.
It is important to remember that replacement anodes should be ordered well in advance of the date for which replacement is required. We strongly recommend that spares are always kept available on hand to ensure that replacements are made immediately as they are needed.
Anode life is 36 months, for this application, under normal operation.
Anodes will automatically switch off when consumed. The LED display on each anode control panel will change from green to red when anode needs replacing.
