The analysis of offshore industry transition - acceleration from oil & gas to wind

Kołakowski P., Rutkowski G.

The present paper provides an overview of the current state and future trends of the offshore sector worldwide, as well as the relationship between the oil and gas (O&G) and the wind power industry offshore. Study on the offshore energy transition basis on review of literature, reports, and outlooks of main energy agencies, classification societies, and main offshore companies - their pathways and ambitions. A comparative analysis of the oil prices to their extraction at sea. Analysis of new build and scrapped drilling units, and their utilization. This is followed by correlation analysis between the emergence of new projects in O&G and wind farms offshore. The new and cheaper technology, and ambitions to reduce greenhouse (GHG) emission to zero levels, favor renewable. The results disclose that the main O&G companies start investing in renewable technologies. The offshore energy transition has already begun and accelerating. Nevertheless, full transition will take a while, as the global power demand is still too high to be covered only by a renewable source of energy. The number of annual O&G assets decommissioning is double in size compared to the new projects, and Mobile Offshore Drilling Unit (MODU) utilization average of 60%. Offshore wind develops dynamically, and the forecasts show that this trend stands at the same high level to cross a number 100 GW produced from offshore wind globally in 2025, but there is a visible lack of Mobile Offshore Wind Power Service Operations Units (MOWU). If well planned there is room for mutual benefits between O&G and wind within the offshore sector due to re-orientation measures.

Bioactive ceramic coating solution for offshore floating wind farms

Biofouling is a natural phenomenon that consists of the accumulation of living organisms on an artificial surface submerged or in contact with water like Offshore platforms. This study highlights the need for offshore floating wind farms structures to consider the choice of material used in offshore applications to minimize microbial-associated and corrosion problems. For this purpose, differences in the total of seawater biofouling attached on two coated paints and three ceramic coatings in carbon steel for offshore structures were evaluated and compared. All ceramic coatings were made of incorporating, by electrophoretic deposition, active ceramic particles against biofouling as copper, silver, zinc and titanium. This experiment consisted of testing ceramic coatings and conventional paints in a real environment with high biological activity and at the same time in a shallow marine environment for a period of 1 year, which provided positive comparisons with the standard system (ASTM-D3623) for using in protecting offshore marine structures.
