Study Notes

Impact of Marine Growth on Offshore Structures

Marine growth, including fouling, has a significant impact on offshore structures, increasing their weight and altering their hydrodynamic properties.
This can lead to a reduction in the structure's design life and an increase in maintenance costs.

Inaccurate Calculations of Strength

Calculations of the strength of offshore structures are often erroneous due to the failure to account for the additional weight and changed hydrodynamic properties caused by marine growth.
Ignoring marine growth can result in structures being over- or under-designed, leading to safety issues or unnecessary costs.

Vulnerability to Fouling

Offshore structures are not immune to fouling, and it is a common problem in the offshore industry.
Fouling occurs when marine organisms such as mussels, barnacles, and seaweed attach themselves to the structure.

Impact of Fouling on Load

Fouling increases the load applied to offshore structures, which can cause structural failure or reduce their design life.
The increased load is due to the added weight and changed hydrodynamic properties caused by the attached marine organisms.
