Wastewater and waste management
Advantages of operating on LNG are most evident from gures: the reduction of sulphur oxides and soot emissions reaches 100%, nitrogen oxides emissions decrease by 76%, and carbon dioxide emissions — by 27% as compared with power plants running on conventional heavy fuel.
A key focus of the Sovcomflot Group’s environmental protection activities is reducing the amount of wastewater and waste that gets into the World ocean during ship operations. These activities are carried out pursuant to the internal procedures of the Group, which encompass the requirements of both international and domestic legislation.
At present the Group’s ships are equipped with wastewater treatment systems that combine mechanical, chemical, physical-chemical (including electrolysis) and biological methods. All wastewater treatment plants on board ships have the approval of classification societies confirming compliance with the requirements of Annex IV of the MARPOL 73/78 Convention. The quality of discharged water is confirmed by a wastewater plant certificate (type approval certificate).
Management of garbage produced on ships during operations is also organised in strict compliance with Annex V of the MARPOL 73/78 Convention, which governs the prevention of pollution by garbage from ships.
