NEPCOAT stands for the Northeast Protective Coating Committee and is comprised of tenmember Departments of Transportation, from Connecticut, Delaware, Massachusetts, Maine,New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont. NEPCOATwas founded in 1992 and has for thirty years evaluated and qualified paint systems for use onbridges, both for shop-applied new steel, and field-applied totally cleaned existing steel.
The drive towards renewable energy, requirement for reduction in fossil fuel consumption and emission of carbon dioxide has received substantial attention from governments and researchers worldwide during the last few decades [1]. The exploration of renewable sources of energy has been grouped into wind, geothermal, tidal and solar energy. Solar energy has shown great promise due to the abundant amount of energy reaching the Earth [2, 3]. Electricity generation from solar irradiation can be achieved by photovoltaic (PV) and photothermal conversion [4].

High strength low alloy (HSLA) steels are preferred for oil and gas pipelines due to their outstanding mechanical properties. Sulfide stress cracking (SSC) has been a major problem for the application of HSLA carbon steel because of the wet H2S environment which commonly presents in oil and gas industry. Several techniques are applied to the study of SSC of steels, including constant load test with smooth specimens and DCB testing.
Maintaining the integrity of oilfield equipment is essential to its safe operation and to maximize the efficiency of production. The integrity of oilfield equipment can rely on material selection and control of conditions, however, it is commonly maintained by the applications of chemical corrosion inhibitors (CI). Prior to use, these chemicals must be shown to perform as desired under the field conditions in question. To achieve this, chemicals are often evaluated using robust laboratory-based screening studies to identify potential candidates.
