Van der Waal B.V., established in Papendrecht (the Netherlands), has recently received the Silver Green Award for her crane ship Rival. That age is no obstacle for obtaining a Green Award, proves the family business with this crane vessel. Indeed, more vessels have obtained a Green Award, but that a more than fifty-year-old ship gets the recognition for sustainability, is special. Van der Waal has been advised by Berger Maritiem for obtaining this Green Award.
What was the reason from Van der Waal?
One of Van der Waal’s clients is Port of Rotterdam Authority. This organization has expressed its ambition to be the most sustainable port in the world. Among sustainability, they mean the greening of the industry, logistic and the quality of the environment. In addition to the Rotterdam Port Authority that they are trying to improve their own performance, they also encourage sustainable entrepreneurship in the port area and call for sustainable innovation in the entire supply chain.
The Rival dates from 1965. By making this crane ship more sustainable, Van der Waal wants to ensure the continuity of their business with the Rival in the Dutch ports.
What kind of sustainable measures has Van der Waal taken with the Rival?
First of all, the crane ship has been motorized with a Volvo D16 engine, meeting the CCR2 emission requirements. In addition, they have installed a SCR catalyst and diesel particulate filter (DPF) from Fischer Abgastechnik. After an independent measurement, it was found that the exhaust gases are already cleaner than the future EU Stage V emission requirements. Besides that, Van der Waal has invested in, for example, a closed sewage circuit, led lighting and a shaft seal.
Another sustainable aspect of the Rival is that the crane ship has got bottom doors for unloading the space content. Wim van der Linden from Van der Waal: “Besides the fact that unloading the 750 kuub of space content goes fast, there is hardly no energy needed thanks to the bottom doors. As a result of that, we have a very low CO2 emission per dredged kuub. Unfortunately, this aspect did not fit into the Green Award systematic, otherwise, I think, we could be awarded with gold.”

How did we help Van der Waal?
We started with mapping of the current situation. After that we have made an action plan (in which we have put in all practical options) and have done a feasibility study together with Van der Waal. Wim van der Linden is happy with the achieved result.
