Ocean engineers could combat the corrosive ocean water by investing a new material which does not corrode in the ocean. Ocean engineer are prepared people to make a build systems that monitor an control coastal environment.
For preventing corrosion requirement of elimination or suppression using two principal methods, cathodic protection and coatings. They are normally, cathodic protection system are used in conjunction with coating systems.
Main objective or aim of the cathodic protection is to suppress the electrochemical reaction taking place. These engineers and naval architects work along the coast- both offshore and land.Sometimes these engineers work on oil rigs, where they oversee the repair of system that they may have design.
