ENDEGS degasses ships in the Netherlands

For years, ENDEGS and in particular its CEO Kai Sievers have gone to great effort to put an end to degas ships into the open air by means of an extremely efficient, patented mobile degassing technology. Its efficiency was recently demonstrated once again in a test project at the port of Rotterdam in the Netherlands initiated by the Safety Region Rotterdam Rijnmond and the environmental protection agency DCMR. One objective was to confirm ENDEGS mobile degassing systems meet all safety requirements. The other objective was to see if all emissions restrictions were met. Kai Sievers: “Both the nitrogen oxide and the carbon dioxide values were very low, in some cases ten to twenty times lower than with other technologies. We also demonstrated that with mobile degassing we are able to prevent the escape of benzene and petrol into the outside air, as required by regulatory authorities.”

So, ENDEGS degassed the tanker Visioen with 3300 m3 MTBE. Degassing the ship took just 6.5 hours at 1000 m3 per hour; furthermore, with ENDEGS’ in-situ process there was no further waste, and no materials accumulated to be fed to the waste management.

And this is where the difference from other degassing technologies really comes into play. ENDEGS isn’t just 40 percent faster than other degassing technologies – meaning 40 percent less time in port, 40 percent faster reloading and 40 percent lower costs – ENDEGS also has the highest emission reduction with a rate >99,99%. Sievers: “What’s at least as important for me as a family man and company CEO is that we release far less emissions, by a factor of 20, than other market players. And that unlike them, our degassing leaves no waste of any kind that needs to be disposed of. Our competitors use activated carbons and nitrogen to reliquefy gas, but this liquid then needs to be disposed, so the waste and emissions problem is simply moved someplace else. In contrast, we burn away all the hazardous gases, really all of them, almost 100 percent, as we recently did once again in Duisport.”

And here the circle closes. In Duisport, Germany, after years ENDEGS has now been able to offer a ship degassing site with removal of cleaning water from tanker ships. Sievers: “I would be very delighted indeed if this could be done soon in ports in the Netherlands, like Rotterdam, Amsterdam and/or Antwerp. Today the technology is so simple to operate and use. The risk is essentially zero – I think there is no more reason to hesitate.” The recently degassed tanker in Duisport with 2500 m3 of petrol was again degassed without problems to 0% LEL in ten hours.

A summary of the excellent results of the ship degassing test in Rotterdam:

  • Total hydrocarbon emissions: 1.9 mg/Nm3
  • Benzene emissions: < 0.53 mg/Nm3
  • Emissions reduction > 99.99%
  • For example, NOx emissions 33.6 – 76.4 mg/Nm3

Whether alkylate, benzene, eurobob, naphtha, reformate, toluene, xylol or other tank contents, ENDEGS is the expert for ship degassing. According to Kai Sievers, “more and more customers are taking advantage of our ship degassing service. We’re delighted about this. It’s not just good news for us, it also means more safety for ship crews and other involved parties and makes an important contribution to environmental protection.”
