Protection Systems
Built for the Sea
From marine growth prevention to full cathodic protection, Cuproban engineers comprehensive solutions for every vessel type and offshore structure — designed to perform where failure is not an option.
Marine Growth Protection Systems
Marine organisms such as barnacles, mussels, and tubeworms colonise sea chests, pipework, and heat exchangers with alarming speed. Left unchecked, they restrict flow, cause overheating, and demand costly dry-dock interventions. Cuproban MGPS systems use controlled copper and aluminium ion release to prevent biological fouling at the source.
- Continuous copper ion dosing into seawater systems
- Protects sea chests, box coolers, and pipework
- Suitable for all vessel types and sizes
- Low power consumption — typically under 10W
- Minimal maintenance — no moving parts
- Class society approved installations
Corrosion Control Systems
Electrochemical corrosion is one of the most destructive forces acting on marine structures. Seawater is a highly conductive electrolyte, and dissimilar metals in close proximity create galvanic cells that eat through steel and bronze fittings. Cuproban cathodic protection systems — both sacrificial anode and impressed current — neutralise these forces and extend structural life.
- Impressed current cathodic protection (ICCP)
- Sacrificial anode systems for hulls and appendages
- Internal pipe and tank protection
- Shaft earthing and bonding systems
- Monitoring and control panels
- Full system design and engineering support
Offshore & Fixed Structure Solutions
Fixed platforms, FPSOs, semi-submersibles, and jack-up rigs face unique challenges — continuous immersion, high flow rates, and remote locations where maintenance is expensive and disruptive. Cuproban designs bespoke MGPS and corrosion control packages for offshore assets, engineered for reliability and long service intervals.
- Bespoke system design for fixed and floating structures
- High-flow MGPS for large-bore pipework
- Remote monitoring and telemetry integration
- Subsea anode systems and retrofit solutions
- Compliance with offshore regulatory standards
- Commissioning and ongoing technical support

Support
Ongoing technical support, spare parts supply, and system monitoring throughout the vessel's service life.
What Cuproban Does
Marine growth such as mollusca, algae and slime enter seawater systems and find spots where temperature, pH factor and environmental conditions are right for settling and breeding. The result is turbulence, blocked pipes, impaired heat transfer efficiency — and the time-consuming, costly business of cleaning the system. Cuproban eliminates this at source.
Reduction of Corrosion.
Inhibits Scale Formation.
Cuproban electrolytically treats seawater at the point of entry. A "floc" is produced by copper and aluminium (or soft iron) anodes in controlled amounts, spreading throughout the system to combat fouling and corrosion. A unique anode-wear monitoring feature makes this a simpler, more trouble-free system for the operator.
How Cuproban
Is Installed
Fitting anodes in the sea chest is simple and can be designed to coincide with dry-docking schedules, or for extended periods, combined with an inboard (changeable at any time) installation. In some installations such as offshore platforms or rigs, where dry-docking is not possible, an inboard-only type installation is usually preferred.
The whole system is controlled from a central Control Panel, with instrumentation to allow the operator to monitor each anode's performance individually. Separate controllers for each pump room are available for rig installations.
