EFFECTS OF MARINE GROWTH AND HYDRODYNAMIC LOADING ON OFFSHORE STRUCTURES

Abstract

Marine growth is known to give adverse effects on the performance of
offshore structure, It presents will roughened the surf aces of the structure
hence increase its drag coefficients, Structures with the best protection
scheme from marine organisms would after f ew years start to be covered
by various types of growth. Generally, it was also recognised that the
most important source of loading exerted on offshore structure comes
from hydrodynamic action which are influenced by CDand CM values,
In this paper type of marine growth usually found on offshore
structures are mentioned and their effects on hydrodynamic loading are
highlighted. Usual ways ofcontrolling and removals ofmarine growth are
also discussed Data ofmarine growth distribution on a typical structure
are presented and discussed
