An Ocean-Powered Marine growth preventer

Rapid and chemical-free marine growth removal for tubulars in the splashzone within as little as two days.

Ideal for use on:

  • Offshore oil and gas jacket structures
  • Offshore wind farm jacket foundations
  • Jetty and terminal piles
  • Splashzone level structures
The combination of marine growth and wave loading on offshore structures increases the probability of tubular defects and failure. MGP-i enables us to reduce this risk significantly while also reducing or eliminating the need for periodic cleaning by divers.

MGP-i is a structural integrity management tool that uses it's own buoyancy and natural wave power to remove existing marine growth permanently and prevent regrowth on protected offshore structures.

Installed by AquaTerra's rope access teams, MGP-i is a proven low-cost, long-term maintenance solution for marine growth removal and prevention in the harshest of environments. It allows visual inspection of the tubular surface to be conducted and reinstates structural capacity by reducing wave loading.

Patented and manufactured by IEV Group, its modular design means the MGP-i can be quickly and easily configured to fit any tubular and requires no maintenance following installation.

Easily removing soft and hard growth material, the MGP-i is powered solely by wave action, so it’s environmentally friendly and works 24 hours a day, 365 days a year.
