Abstract: Disclosed is a method of inhibiting the growth of marine organisms on a marine structure, by applying onto or into the marine structure a phenylamide compound. These compounds may be directly incorporated into the marine structure during manufacture, directly applied to the structure, or applied to the structure by means of a coating.

Abstract: The invention describes a process for controlling contamination of oil production system waters by sessile bacteria, comprisinga) addition of a slug dose of a biologically effective amount of a quick-kill biocide, simultaneously with or followed byb) intermittent addition of a biologically effective amount of a control biocide.This dosing regime is found to be surprisingly effective when compared with known dosing regimes.
