THE MARINE GROWTH PROBLEM

Marine Growth has two adverse consequences to submerged structures; it increases  diameters and  surface  roughness  of  structural members and appurtenances, especially in the wave zone, where a combination between wave action and thick  marine  growth  profile  causes  significant  increase  in  lateral  and  cyclic  loadings.

Marine growth can indirectly cause corrosion by penetrating into the protective coatings and creating an environment for microbially induced corrosion (MIC), thus exposing the steel to the hostile corrosive environment.

IEV’S 35-YEAR PROVEN NET ZERO SOLUTION

IEV’s Net Zero marine growth control technology focuses on breaking down the marine colonisation process by preventing the formation of the microbial slime or micro‐fouling on offshore structures. Once installed, our patented “Ocean-Powered” Marine Growth Preventers (MGP) requires no other than the endless and free ocean energy from waves, swells, currents and tidal fluctuation to power its continuous operation.

IEV’S MGP-i :

• Removes and prevents marine growth in a single deployment, a simple-DropNGo installation
• Self-cleaning and requires little or no maintenance
• Can be designed for warranty of up to 10 years
• Does not require any special equipment, mechanical or electrical for installation
• Designed for all ocean conditions and is certified typhoon proof
• Reduces or eliminates the need for periodic cleaning using divers
• Maintaining a marine growth free structures enables “any-time” inspection of the structures
• MGP reduces the dynamic and hydrodynamic loadings on the platform, thereby increasing its structural capacity and Reserved Strength Ratio (RSR). The reduction of cyclic wave loading also significantly improves the fatigue life of joints, hence extends the service life of the platform.
