Abstract: The present invention proposes a resident station of launching and receiving subsea pigs installed in place of THE PLET, in order to enable the application of subsea rigid pipes and the full compliance with the routine internal inspection requirement for monitoring internal corrosion, through bi-directional pigging, mitigating existing operational risks in this type of operation. The invention enables the safe bi-directional pigging of a non-pigable pipe by installing the proposed equipment at the end of the subsea rigid pipe, connecting the pipeline to the main branch in order to ensure shutdown of the pig until the flow is reversed, importing gas from the main branch pipeline, causing the pig to return and be received in the launcher/receiver residing at the FPSO. Thus, the equipment can safely guarantee the periodic and instrumented bi-directional pigging of the pipeline, acting as a launcher/receiver (FIG. 1) residing and aligned to the pipe.

Abstract: The present invention relates to processes of producing a fermentation product from readily fermentable sugar-material in a fermentation vat comprising a fermentation medium, comprising: feeding the readily fermentable sugar-material into the fermentation vat comprising a slurry of fermenting organism; fermenting the readily fermentable sugar material into a desired fermentation product, wherein protease is added during or after feeding of the readily fermentable sugar-material into fermentation vat or during fermentation of the readily fermentable sugar-material into the desired fermentation product. The invention also related to the use of protease for reducing foaming in the fermentation yells generating by the fermenting organism during fermentation of the readily fermentable sugar-material.
