The persistent eutrophication (being too rich in nutrients) of the Baltic Sea prompted the IMO’s Baltic Member States to tackle shipping’s < 0.1% contribution by designating the Baltic Sea as the first Special Area under Annex IV of IMO’s MARPOL Convention [1]. Passenger ships must give sewage to wastewater treatment works (WWTWs) ashore via the port reception facilities (PRFs) or operate a nutrient removal sewage treatment plant (STP) on board prior to discharge. It has been perceived as a positive move. But how special is the Special Area?Rules at sea vs.

Scienco/FAST, an experienced manufacturer of Marine sewage devices (MSD) recently received an extraordinary service order. Or, maybe it’s not that extraordinary.Scienco/FAST, a St. Louis, Missouri-based manufacturer has, over many years, had plenty of experience in dealing with archived orders. In fact, the firm just had a call from a client that needed to replace a part on a previously installed Scienco/FAST system. So what? Well, it turns out that the system was installed onto a domestic tugboat, way back in 1975. That more-than-43-year-old workhorse is still in service. And, so too is the Scienco/FAST system that’s been on board since it was launched.For its part, Scienco/FAST says that this is just one, of countless typical examples of how long the overbuilt Marine/FAST units can last.
