Systems And Services
Cathodic Protection Systems
Cathodic protection (CP) is a method of corrosion control that can be applied to buried andsubmerged metallic structures. It is normally used in conjunction with coatings and can be considered as a secondary corrosion control technique. The primary corrosion control method on any given structure is normally a coating system which can be between 50 and 99 % efficient depending upon age, type, method of installation, etc. A properly designed and maintained cathodic protection system will take up the remainder resulting in a 100 % efficient corrosion protection system.
Zinc & Aluminium Sacrificial Anodes (SACP) Systems
In cathodic protection, a metal anode that is more reactive to the corrosive environment of the system to be protected is electrically linked to the protected system, and partially corrodes or dissolves, which protects the metal of the system it is connected to. As an example, an iron or steel ship's hull may be protected by a zinc sacrificial anode, which will dissolve into the seawater and prevent the hull from being corroded.
Sacrificial anodes are used on pipelines, platforms, subsea structures; wind turbine foundations and monopiles, wave and tidal generators; quay and harbour walls, jetties & pontoons, dock gates; ships and boats hulls, ballast, grey and potable water tanks; power station intake screens and storage tanks. In short any where steel is immersed in water, anodes will be found.
We specialise in manufacturing larger platform, bracelet and flush mounted Anodes, in sizes up to 4000Kg to the exacting standards of the Marine & Offshore industries.
Impressed Current Cathodic Protection (ICCP) Systems
Impressed current cathodic protection systems provide automatic, permanent protection that prevents electrolysis and galvanic corrosion from attacking the submerged surfaces of a broad range of sea-going vessels and fixed or mobile offshore structures. Our systems are the ultimate state-of-the-art, long-term solution to corrosion problems, and are recognized as a superior alternative to sacrificial anode systems, which require frequent replacement.

Marine Growth Prevention System (MGPS)
Ships while sailing use seawater for several purposes. The seawater is used in the ship’s system and discharged after the use. However, seawater contains several marine organisms which enter the ship along with the seawater and deposit and flourish on the parts of the ship’s system. If preventive measures are not taken, the marine growth can cause damage to the particular part in the long run. In this article we will learn about the causes and effects of marine growth in a ship’s system along with the measures to fight it.
CHLOROPAC® Electrochlorination
Electrochlorination in general means treatment by on-site generation of equivalent chlorine in the form of a low concentration of sodium hypochlorite in a solution of seawater or salt water and injecting this solution into the main water stream requiring treatment.

To help meet ballast water treatment management standards as outlined in the 2004 IMO Convention for the Control and Management of Ships' Ballast Water and Sediments, Siemens Water Technologies has developed a ballast water treatment system that provides a reliable, environmentally sound solution that is designed to protect against the proliferation of aquatic invasive species.

Cathodic Marine Engineering has further utilised it’s CP facility , by branching out to Engineering & Fabrication works. We been helping ocean-faring vessels re-condition and repair their engines effectively . We strive to reduce operational downtime for our Local and International customers using the most cutting edge repair and reconditioning techniques and equipment.
