Ongoing project components

Onshore Power Supply for ships at port
One important measure to minimize air pollution in a port is the offering of onshore power supply (OPS) to ships at berth, because shore side electricity greatly reduces emissions and noise from ships normally exuded from ship auxiliary engines. Electricity facilities have been developed and installed in a number of the partner ports.

In Cleanship, the Port of Oslo, in close cooperation with Color Line, will elaborate a pilot case on how shore side electricity could be established for large vessels with huge power demand. Their work will result in a report presenting a readymade technical/financial solution. Moreover, a handbook on OPS will be developed, which then could be used as a planning tool for different port/ship/line power constellations and pilot installations.

Port reception facilities for sewage
In July 2011 IMO (MEPC 62) approved the most recent amendments to MARPOL Convention Annex IV, which are expected to enter into force on 1 January 2013. The amendments introduce the Baltic Sea as a special area under Annex IV and add new discharge requirements for passenger ships while in a special area; discharge of sewage into the sea from passenger ships will be prohibited unless the ship uses an approved sewage treatment plant, capable of reducing also nutrients on board, according to established concentration standards. Alternatively, untreated sewage could be delivered to an onshore port reception facility (PRF), leading to a waste water treatment plant. From 2016 all new passenger and cruise ships are not allowed to release their sewage into the sea. From 2018, the same ban will apply to the rest of the passenger and cruise ships travelling in the Baltic Sea.

In Cleanship, a study with following aims will be reported: 1) to create a common understanding on technical and operational aspects on sewage delivery to Port Reception Facilities (PRFs), 2) to suggest constructive solutions for functional and effective system for delivery, reception and treatment of sewage from passenger ships, using four case ports, 3) to create an outline for a guidance on technical and operational aspects of sewage delivery to PRFs, 4) to discuss international and national regulations and policies and lift the economical perspective of providing adequate PRFs in a port.

Liquefied natural gas and other alternative fuels
In 2015, shipping in the Baltic Sea will have to comply with revised MARPOL Annex VI regulations, i.e. it has to manage a sulphur content of 0.1% instead of 1.0% in fuels. There are more than one fuel solutions. Different ship fuel types and exhaust filter solutions are now being intensively studied and discussed also within the Cleanship project. Some of them are presently under thorough examination and development into full scale solutions; others are still under testing in an early stage, with very promising but not yet fully revealed final results.

Within the Cleanship project two pilot projects on liquefied natural gas (LNG) as ship fuel will be elaborated; The Port of Klaipeda will elaborate how local small scale LNG logistics to ships at docks in the Port of Klaipeda can be organized from a large LNG import terminal. This study will result in a technical and financial investment plan. The Port of Rostock performs a study of LNG as fuel for ferries and cruise ships.


Elaboration on models for environmentally differentiated port fees
Several initiatives with the purpose to assess and improve the environmental performance of ships exist. A description and assessment of these initiatives will be used, together with result from interviews with partner ports to model a market based economic instrument for ports. By this, incentives shall be set for ships producing low emissions, managing waste and ballast water, using environmentally friendly technologies and having high safety standards for the EU Baltic Sea action plan.

Environmental Port Index
The work regarding environmentally differentiated port dues (see above) are being accompanied by the development of an Environmental Port Index. Such a port index is believe to act as a catalyst and indicator of good practice in environmental management of port and shipping interests. Environmental shipping and port indexes are of paramount importance for several large ports and there will be a unique opportunity for the Baltic Sea Region to take the lead and provide an excellent show case for other maritime regions.
