Offshore structures

Cathodic Protection This electrochemical method of corrosion control has found wide application in the protection of carbon steel underground structures such as pipe lines and tanks from external soil corrosion. It is also widely used in water systems to protect ship hulls, offshore structures, and water-storage tanks. 

Designing with ceramics ice forces on offshore structures... 

For complex offshore structures or where foundations may be critical, finite-element analysis computer programs with dynamic simulation capability erm be used to evaluate foundation natural frequency and the forced vibration response. 

Failure and Inventory Reporting System Offshore Oil and Natural Gas 8,000 failure events and causes Inventory data on ASME coded devices Safety and pollution prevention devices on offshore structures, eg. subsurface safety valves 72. 

The Failure and Inventory Reporting System (FIRS) program was developed by the Geological Survey Division of the U.S. Department of the Interior for safety and pollution prevention devices on offshore structures that produce or process hydrocarbons. The program collected data on mechanical and some electromechanical systems on offshore oil platforms. About 8,000 failure events were documented. Access has been limited to internal materials management system use. No real-time access or periodic output products have been available.

These anodes, like platinised Ti may be supplied in different forms e.g. rod, tube, mesh, wire, etc. They may be used for the cathodic protection of offshore structures, heat exchangers, or even pipelines as they can be installed in the soil surrounded by carbonaceous backfill, and are comparable in cost to platinised titanium. ...

Offshore structures that handle or process hydrocarbon materials. 

The Georgian onshore gas resources of Eocene and Cretaceous structures are assumed at 269 bcm. The proven Near-Tbilisi-region reserves in the Eocene structures of the Samgori, Rustavi and Ninotsminda fields approximately equal to 3.5 bcm. The data on gas prospective resources obtained by modem three-dimensional seismic survey over the Black Sea offshore structures are not available yet.

Galvanic anode systems are generally used in well-coated electrically isolated structures, offshore structures, ship hulls, hot-spot pipeline protection, heat exchanger water boxes and other environments of resistivity below 10000 Q cm. 

Typical steel structures exposed to marine environments are (i) marine piles (ii) offshore structures (iii) vessels and (iv) others. The corrosive zones encountered in marine environment are (i) atmospheric (ii) splash (iii) tidal (iv) submerged and (v) seabed-embedded zone.
