The project was implemented in two phases, which for formal reasons were subject to different design and obtaining the necessary administrative decisions.
The subject of the contract is the selection for a period of four years of the operator of the infrastructure for the collection of sewage from passenger ships and ferries at the Port of Gdynia, which was implemented as part of the project no. POIS.03.02.00-00-0076/19 entitled "Construction of infrastructure for the collection of sanitary sewage from ships in the Port of Gdynia", co-financed by the European Union.
The project was implemented in two phases, which for formal reasons were subject to different procedures for designing and obtaining the necessary administrative decisions.
The detailed scope of infrastructure covered by Phase I (sewage collection and transmission installation) and Phase II (sewage treatment installation and structures) is described in the detailed design and as-built documentation constituting Annexes 12 to 17 of the SWZ.
The order includes comprehensive service of the mechanical-chemical sub-treatment plant located on XXVII Square at 45 Polska Street in Gdynia and the implementation of a service consisting in the collection and management of sewage from ferries moored at the Polish Quay and cruise ships moored at the French Quay.
As a general rule, it is not envisaged to use the sub-treatment plant infrastructure to handle waste water from sources other than those indicated in the previous sentence.
Estimation of the amount of wastewater to be managed in a calendar year
An element of the subject of the contract is the collection and management of sewage from passenger ships moored at the French Quay and ferries calling at the new public ferry terminal at Polska Street.
The Ordering Party does not have actual data from the above-mentioned newly built facility. Therefore, to estimate the expected amount of sewage from ferries, the wrapping of at least 3 ferries per day and the average discharge of sewage with a cubic capacity of 35 m3 / ferry were assumed.
According to the INTERNATIONAL MARPOL Convention, a total ban on the discharge of sewage into the waters of the Baltic Sea has been in force since 2021. However, due to the COVID-19 pandemic, in the years 2020-2021 the number of passenger ships calling at the Port of Gdynia decreased drastically, while in the five years before the pandemic, on average, about 50 passenger ships called. Therefore, the Ordering Party does not have real data in this respect, and to estimate the expected amount of sewage from the above-mentioned ships, the call of 50 ships per year and the average discharge of sewage with a cubic capacity of 300 m3 / ship were assumed.
The Ordering Party informs that the list of anticipated calls of passenger ships is available on the website of the Port of Gdynia Authority S.A. (www.port.gdynia.pl) in the cruise ships tab and is constantly updated.
To sum up, it is assumed to receive approx. 35 000 m3 of sewage from ferries and approx. 15 000 m3 of sewage from passenger ships, which gives a total of about 50 000 m3 during the year. The indicated quantities result from the assumption of calling 3 ferries a day and 50 cruise ships during the year. Due to the entry into force of new regulations obliging ships to return waste in the port, the Ordering Party is not able to accurately estimate the amount of sewage discharged.
