Through hull fitting anode

Manufacturer's part number.

Lot number of item.

Date when the equipment or vessel was originally manufactured.

Period of the product warranty from purchase date.

Date item was purchased.

Calculated the item's warranty expiry date based on the purchase date and warranty period.

Date item was decommissioned.

Date the item was installed. Note this may be a different date to the commissioning date.

Date when the item was permanently removed or decommissioned.

Free text input as the result of visual inspection.

Date of last visual inspection.

Time based interval between visual inspection.

Date when the next visual inspection is planned calculated from the last inspection date and time based inspection interval.

Date of next planned visual inspection.

The recorded mass of the anode at the time of installation. Forms the baseline for all subsequent depletion calculations.

The measured mass of the anode at the time of inspection. Used to calculate depletion percent and material loss.

Remaining mass of an anode expressed as a percentage of original mass.

Forecast time until the item reaches its replacement threshold.

The number of bolts, screws, or other fixings securing the item in place.

The primary metal composition of the sacrificial anode.

The physical shape of the anode body. Determines suitability for specific mounting locations and protection zones.

The mechanical method by which the anode is secured to the vessel or fitting.

The fitting material or metals the anode is designed to protect against galvanic corrosion.

The water type in which the vessel operates. Directly determines correct anode material selection and expected depletion rate.

American Boat and Yacht (ABYC) reference standard.

U.S. Military Specification (MIL-DTL).

DNV (formerly Det Norske Veritas) classification society standard.

Expected service life under normal conditions as declared by the manufacturer or derived from standard practice.

The electrochemical potential measured at the protected metal. The primary ABYC E-2 performance criterion.

The electrical resistance between the anode and the bonding system. ABYC E-2 requires connections of 1 ohm or less for effective cathodic protection.

Anode electrochemical capacity

Identifies if an anode is electrically connected to the vessel's cathodic protection bonding system.

Length of item.

Width of item.

The weight of an item.

Outer diameter of an item.

Internal diameter of the fitting — critical for flow calculations of water, air or other gases and fluids.

The width of a slot in an item such as an anode.

The length of a slot in an item such as an anode.

Distance of the centres between two slots of an item such as the slots in an anode.
