LAND SeaBis now available, click: here

SeaBis Full Isolation Method

Applies to: Commercial, Naval, Police, Customs, Tugs, OIl Rigs, liquid transfer.
Where power applied exceeds 200 hours per year.

Commercial Vessels  of any hull material, fishermen, tugs, ferries, barges, oil rigs, police, naval vessels, water use systems from wells, pipes, monitors, pumps - wherever water is present with powered equipment. Where power is ON for more than 200 hours per year.

After 15 years of development and trials on over 220 vessels, followed by another 220 vessels we confidently guarantee the SeaBis System, when Process of Elimination instructions, are completed, will protect your vessel and equipment from electrolysis corrosion.

Undisputable fact:  When all wet metal is electrically open circuit (no connection) with full power applied and in full use then electrolysis corrosion is impossible. That is the result of the SeaBis System.

It is absolutely and vitally important the SeaBis System be hard wired and tests completed with power fully applied and equipment in full use.

The reason is most electrics and electronics only fully power up when in actual full use. It is often this final stage that generates the electrolysis.

The SeaBis MUST be hard wired, one to every independent (never paralleled) source of DC power. So one SeaBis for any number of engines and batteries / banks providing they can be paralled at least once per month. The paralleling can be for testing with SeaBis or for charging - any paralleling.

Remember: One wire as thick as a human hair carries 100 times the electrolysis than will cause visible corrosion within 3 months. So use SeaBis to eliminate every cause - including the Cabin wiring. Even a very small battery such as that for communications backup, holds over 100 ampere hours. This is vastly more energy than will cause electrolysis you can see in 3 months.
For photographic proof see: Photographs.

From vast experience we know 80% of vessels cleared of electrolysis will develop a new cause within one year. We have seen antennas that work perfectly cause electrolysis making thousands of visible 3 to 4 millimeter holes in a 5 millimeter steel hull in three months. The SeaBis System eliminates EVERY cause. So hard wire SeaBis and follow Process of Elimination supplied with SeaBis.

The procedure:
SeaBis is hard wired, one to every independent (never paralled) source of power. Full Process of Elimination instruction are supplied with SeaBis, however, briefly:

If SeaBis indicates a fault then there are two methods of locating the cause:
1. The simpler method applies to 90% of vessels: Find the battery negative common junction strip. Usually a brass strip with a hole and screw for every cable. Disconnect wires until SeaBis indicates Normal. The last equipment you disconnected was causing electrolysis.

2. Applies to the remaining 15%. Disconnect equipment wires in PAIRS. The reason is the engine cooling water, in or out of the water, will make a path for electrolysis via the one wire left connected. Keep disconnecting pairs of wires until SeaBis indicates Normal.The last equipment you disconnected was causing electrolysis

It is much the easiest method to get to a Normal state, then add one suspect pair of wires at a time. The reason is the causes of electrolysis are effectively all in parallel. - Think about it. All parallel faults have to be eliminated first. Get to a state of Normal, then add one suspect pair of wires at a time. Disconnect that pair if they produce a fault light. Leave that pair disconnected.

Reconnect wires in pairs, removing a pair when one wire indicates a fault.

When all pairs of wires are tested you will be left with one to four pairs that cause electrolysis.
Follow Process of Elimination instructions, to correct the cause/s.

On completion all the wet metal in your vessel will be electrically open circuit. In home terms we have pulled the electrical plug out of the socket. Your vessel is immune to electrolysis. It can neither cause nor be affected by electrolysis.

It's the engine...
It is deceptively easy to blame the biggest target. In nearly every instance there is a cause at least as guilty of electrolysis as a recreational engine. Remember: One wire as thick as a human hair carries 100 times the electrolysis that will cause visible corrosion within 3 months.

So use SeaBis to eliminate every cause - including the Cabin wiring. Don't get caught with unnecessary repair costs.

To eliminate electrolysis we must correct every cause. Even the House / Cabin. That will be the result of SeaBis System Process of Elimination.

If in any doubt then contact us at 61 (0)8 8556 6593, mobile: 0417 882 818 or Contact Details here or seabis@bigpond.com. We will respond. On line assistance is included in the price of the SeaBis System.

Full colour coded, indexed with explanations, circuit diagrams and theory explanations are provided with every SeaBis System.
