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.

New rules that entered force at the start of 2020 to reduce sulphur emissions from ships are leading to significant hikes in vessel operational expenditure, members of theshipping industry say.Using low sulphur fuel oil (LSFO) can add as much as $20,000 to the operational expenditure for each ship per annum, said Sacha Cornell, fleet manager, Norbulk Shipping, speaking during a webinar organized by trade association management company Maritime AMC. “I would guesstimate that the extra cost for additional sampling…

The IMO’s MARPOL Annex IV is being revised to confirm the lifetime performance of Sewage Treatment Plants (STPs). This may finally bring about grey water regulation – a necessity that is long overdue.Black Water and Grey WaterA ship’s sewage (black water) is collected from toilets, urinals and hospitals. The IMO’s MARPOL Annex IV prohibits its discharge, except when treated by an STP or discharged at > 12nm from the nearest land. A ship’s grey water, collected from showers, wash basins…
