Cleanest Ship
Cleanest Ship was a sub-project of the European research project Creating ( Concepts to reduce environmental impact and attain optimal transport performance by inland navigation ), which dealt with the reduction of pollutants and consumption in inland navigation . By using all available technical possibilities, optimal transport results and the highest possible pollutant reduction should be achieved. The project started on November 20, 2007 and lasted one year.
Those responsible for the project expected that the use of sulfur-free diesel fuel , the installation of a speed control and navigation system ( Advising Tempomaat ) and soot filters , as well as catalytic exhaust gas treatment would result in fuel savings of between 5 and 10%, a reduction in nitrogen oxides by 86% and sulfur oxides by 99.5%, soot particles by 96% and carbon dioxide by 5% could be achieved. For this purpose, the lubricating oil tanker Victoria of BP Shipping , Rotterdam, was equipped accordingly.
Data on Victoria
The Victoria operates in the port area of Rotterdam. She is a double-hulled tanker 69.96 m long, 11.44 m wide and 2.98 m draft. 1500 m³ of lubricating oils of various qualities can be transported in 17 separate tanks for supplying seagoing vessels. The ship is equipped with an advising tempomaat , which gives the skipper the most economical route and engine speed. The engines run on sulfur-free diesel fuel that complies with the EN 590 standard, which is also used in the automotive sector. This is a prerequisite for ensuring trouble-free and optimal operation of the soot filters and catalytic converters . In addition, special engine oils are used.
The exhaust gas cleaning system consists of filters with a catalytic coating made of silicon carbide to reduce nitrogen oxides. It works with selective catalytic reduction (SCR). Here, ammonia , which is injected into the exhaust gas in the form of a urea solution , reduces the nitrogen oxides to nitrogen and water. The filters also work at low exhaust gas temperatures.
Results of the Cleanest Ship Project
In 2009, the results of the operational phase were published in a final report. The majority of the intended goals were achieved. The measures implemented led to a significant reduction in emissions and did not disrupt normal operations. For the evaluation of the results, the fuel consumption, the energy output of the main engine, the kilometers traveled and the concentration of nitrogen oxides were measured directly, the carbon dioxide and sulfur oxide emissions from fuel consumption and energy output were calculated and the particulate matter concentration was estimated from the test bench results. It turned out that the Advising Tempomaat showed no direct benefit in reducing fuel consumption, since the tanker mainly performed its task on short distances and under high time pressure. Therefore, neither a reduction in fuel consumption nor a decrease in carbon dioxide emissions could be achieved. In relation to nitrogen oxide emissions, the reduction averaged 82%, which means that the ship complied with the Euro 5 emissions standard . The fine dust emissions fell by 97% and thus complied with the Euro 6 standard. By using the sulfur-free diesel fuel, the pollution with sulfur oxides is reduced by almost 100% compared to conventional marine diesel.
Some of the methods used in this demonstration are already used in commercial inland shipping. For example, in the case of the Futura carriers , which were largely developed with funding from the Federal Environment Ministry , the exhaust gas is also treated with particle filters and SCR technology.
Creating
Creating was a project of the European Commission in which 27 partners from nine EU countries took part between 2004 and 2008 (scientific institutes, shipyards and companies involved in inland shipping). The aim of the project was to make inland waterway transport more competitive than road transport and to shift part of the constantly growing road traffic to inland waterways. The focus was on measures to increase environmental compatibility , safety and the development of logistics concepts. The focus was on the Rhine , Danube , the north-south connection from Holland to France and the canals in Northern Europe.
