ICCP

Fully protected ship 200neg to hull

Reference anodes-

    zinc which is -450 to hull

    Al which is +600 to hull

So after protecting, the measured valve of reference electrodes will b -250mV to zn and 800 to aluminium

Sacrificial anodes are insulated lead or platinised titanium

Anode current densities range for protection of painted hull is 10-40mA/m2

Total impressed current for a hull in good condition is as low as 20A

Max controller op may b upto 600A at 8V

International Shore Coupling - 64,132,178mm. Bolt 16*50. N withstand 10.5bar

Pressure testing of various

1. Air bottle- to working pr. But if major repairs are done, then 1.25 times working pr
2. Bunker line 1.5 times working pr
3. Hull welding - 1.5bar pr by a 18-20mm nozzle from a distance of 1mtr
4. Rudder 2.45mtr of water head or equivalent pr
5. Stern tube seals 3.5m head by oil from shaft centreline
