Results of 2020:The first river Eco-tanker "Georgiy Moskalev" of prj.RT37 - not only receives, but also reprocesses liquid waste from vessels



Results of 2020 at the online conference "Philosophy of ship design". In 2020, the FIRST self-propelled ecological vessel "Georgy Moskalev" of the project of the Marine Engineering Bureau RT37 for the complex processing of vessel waste appeared on the inland waterways of Russia. The vessel was built for Rosmorrechflot at the repair and operational base of the East Siberian Shipping Company in Irkutsk.
 
On September 30, 2020, the ecological "tanker-factory" of the RT37 project "Georgy Moskalev" handed over for the first time to the treatment "Baikal Harbor" household wastewater from vessels on Lake Baikal.
 
Today, more than 7 thousand units of small size fleet are registered on Lake Baikal, the world's largest in terms of fresh water capacity lake. Previously, only one non-self-propelled station for the complex processing of vessel waste, located at a considerable distance from the northern regions of the lake, carried out the reception of oily and waste water.
 
The head of the Republic of Buryatia, Aleksey Tsydenov, said about the RT37 Eco-tanker: "The ecological vessel is capable of filling water vessels with fuel and oil, accepting both liquid and solid waste for disposal, as well as sewage and oil products from other vessels. to process and purify oily and waste water in order to discharge already clean water into Lake Baikal.
 
Today there are many vessels in operation on Lake Baikal, but there was no effective system for treating water with oil products that need to be disposed of. Now a unique vessel has been created, which can receive liquid waste - waste water and solid domestic waste. The vessel is also a bunkering vessel - it is capable of refueling other vessels. It was specially designed for Lake Baikal. And on all the inland waterways of the country, on the Volga, Neva, there have not been such ships yet".
 
From the speech of Professor Gennady Egorov at the on-line conference "Philosophy of ship design" (first day):
 
"Georgy Moskalev is the first vessel (project RT37 of the Marine Engineering Bureau - note by Gennady Yegorov), built for Rosmorrechflot - a tanker, an ecological vessel.
 
This is a factory tanker. Please note that we have a crab factory, we have a trawler factory, and here, too, is a factory tanker, because it can collect waste and oily waters from other vessel and process them (plus solid household waste - note by Gennady Egorov).
 
A unique vessel built in completely unique conditions, because there are no shipbuilding facilities' on Lake Baikal.
 
Colleagues of the East Siberian Shipping Company were able to build such a beauty in the absence of shipbuilding production.
 
I am delighted because they did it, firstly, on time, and secondly, it is not very simple.
 
This is the first such self-propelled vessel for Baikal. There is one such non-self-propelled vessel, it is the first self-propelled vessel.
 
For such a sensitive place from the point of view of ecology (and in general for all inland waterways of Russia - note by Gennady Yegorov), this is a great event that we managed to realize."

 
For information. The RT37 concept is a bunkering tanker - an ecological vessel that collects oily and waste water, as well as dry waste. The vessel of the RT37 project is called a "factory tanker", since it not only collects waste, but also processes it, and at the same time refueling the serviced vessels.
 
The Marine Engineering Bureau has designed an environmental tanker of the RT37 project, taking into account the fact that the "sacred sea" Baikal requires the highest vessel among the river classes - "M" while ensuring a relatively small draft of 1.80 m.
 
Has overall dimensions (length x width x depth) 51.60 mx 10.23 mx 2.60 m.Deadweight with a draft of 1.8 m is about 280 tons.
 
The oily water cargo system (OWCS) provides closed receival of OWCS from vessels, cleaning and delivery of OWCS by vessel submersible pumps. The tanks are divided into two groups: side tanks for treated oily waters, tanks located along the central line - for contaminated oily waters. An OWCS separator is installed for the purification of oily water. The cleaned OWCS are discharged into the tanks of the cleaned OWCS. The sludge from the OWCS separator is discharged into the sludge tanks. Pumping of sludge to the sludge preparation tank for sludge incineration in the incinerator is envisaged. After the end of unloading from the cargo pipelines, the cargo is displaced by compressed air to the receiving facility.
 
The wastewater cargo system provides closed intake of wastewater from vessels, wastewater treatment and discharge of wastewater by vessel's submersible pumps. A vacuum sewage collection unit is also envisaged for vessels that do not have sewage pumps. The tanks are divided into two groups: onboard treated wastewater tanks, tanks located along the central line for untreated wastewater. For wastewater treatment, a physicochemical type wastewater treatment plant is envisaged. The degree of purification is sufficient to discharge the treated water into the city sewerage system. Treated wastewater is discharged into treated wastewater tanks. After the end of unloading from the cargo pipelines, the cargo is displaced by seawater from the vessel's fire extinguishing system to the receiving structure. Wastewater cargo tanks are equipped with sludge loosening and flushing facilities.
