MariFlex Zevenmanshaven in Vlaardingen a degassing port?

MariFlex Zevenmanshaven in Vlaardingen a degassing port?

If it is up to Ruud Cogels, he will create at the Zevenmanshaven in Vlaardingen a degassing port. Ships that want to get rid of vapours which return after unloading liquid cargo can proceed to his company Mariflex in Vlaardingen, it will be possible to return energy to the local municipality from the residues that are released. These are dreams for the time being, because first Minister Cora van Nieuwenhuizen of the Netherlands has to become convinced that his degassing plant on the quay is more environmentally friendly than the underway degassing, for which he is confident, therefore he is working on a trial to test his method. Some competitors have also joined. The companies have united in the EVRA, the European Vapoury Reduction Association.

The Minister has started the test with alternative degassing plants on shore, because in 2024 it will ban the degassing underway throughout the Netherlands. The released fumes are bad for the crew, local residents and the environment. A nationwide ban could reduce emissions of harmful substances by 98%. Around some densely populated areas and near bridges and locks, all the degassing of benzene and NAFTA is now prohibited, but this is still going on as there are minor controls, or they deviate to places where the sailing degassing is still allowed.

Cogels: "Here in Rotterdam, for example, it is already forbidden, but then for example seagoing ships sail to the North Sea and open their tanks, and then return gas-free. ”So, there's another puff of benzene coming along, which I smell when I am on my sailing boat" An alternative is to degassing at the quayside, but that's not cheap. Cogels: "That quickly costs about 1 euro 50 per cubic metre. For a ship such as the GUADELOUPE, which is now here for the test phase, this would cost between 13,000 and 15,000 euros. Shippers really aren't waiting for that. But it's better for the environment." In 2012 he purchased a so-called Vapour Recovery Unit, or cryogenic condensation installation. The device sucks up the vapours from the cargo tank and cools them with liquid nitrogen at -170 degrees. As a result, the gas vapours become liquid and can be stored and disposed of as a residual product in a separate container." During an earlier trial in Antwerp, the company managed to extract 1400 litres of petrol from the residual vapours from an inland tanker. "You can use that for your car," laughs the director-owner. But it's not that far. According to the environmental law, the residual material is still considered as waste, whilst Mariflex wants to re-use it as a residual product."

I have been working on this for 15 years and have always been surprised at how much money is being thrown away with the degassing, or rather, ventilating the tanks. If we no longer label the residual material as waste, we will be able to make money from new energy in the future.

Mariflex New Ship to Ship location at Paldiski

New Ship to Ship location at Paldiski

Mariflex commenced a brand new Ship to Ship location at Paldiski, close to Tallinn Estonia. An Off Port Limit (OPL) location, sheltered and safe for Ship to Ship operations. The advantage to transfer your cargo is that there are no port costs involved, just an agent and a tugboat for mobilisation and demobilisation of the STS equipment. This is a large STS location and free from any congestion. The STS area (Anchorage “D”) is not far from Russian export ports like Primorsk, St.Petersburg and Ust-Luga.

STS transfer of LPG at Southwold completed by MariFlex

STS transfer of LPG at Southwold completed by MariFlex

On the 14th of August MariFlex Transfer Services BV completed it’s first ever LPG Ship to Ship Transfer at Southwold (UK).With the help of the SEA BRAVO (Sea Contractors) MTS mobilised for a STS Transfer of LPG at Southwold between 2 vessels of almost identical size (180M x 30M). Asked by the client, MTS made a comprehensive Mooring and Transfer analysis for 20.000 tons of LPG (Liquified Petroleum Gas) and when the job was granted to MariFlex a complete STS spread was loaded onto Sea Bravo at MariFlex Premises at Vlaardingen to be delivered to the daughter vessel already on location at Southwold. Sea Bravo also hosted the 2 MariFlex STS specialists to accompany the STS kit.

Within 10 hours the SEA BRAVO reached the Location and commenced installing the fenders alongside the vessel. Subsequently the POAC and STS Superintendent were transferred to the vessel to supervise the fendering and transfer of the special LPG hoses. Despite some initial delays, caused by weather conditions well outside the normal parameters, the MariFlex Team consisting of : Captain David Brant and President Ruud Cogels, managed to complete a safe mooring operation, LPG transfer and safe unmooring well within the weather window that was foreseen when things finally calmed down. Upon completion all gear was reloaded onto SEA BRAVO for the return trip to Vlaardingen and redelivered to MariFlex HQ at Zevenmanshaven after a safe crossing.

The history of MariFlex goes back to 1980 when it was founded. The Group has since than developed from a subsidiary into a fully equipped turn-key marine service company. Presently a team of 20 trained supervisors are operational around the globe, tackling challenges offered by the customers. Thousands of situations have been handled by MPS since those early years and what began a pump rental company has now developed into a fully grown service company, a true one-stop-shop for the petrochemical and marine industry.

The VCRS MVRU – 1100 tackles the ever present challenge to the petrochemical industry, especially tanker operators and barge operators, to comply with ‘green’ incentives and reduce emissions. Especially trans-shipments between Sea-going vessels and Inland barges have been in the sights of Port authorities and Environmental agencies alike.Sea going ships are inerted to less than 8% oxygen in their tanks. Barges are often not inerted, making them incompatible with inerted ships when vapour balancing. During transfers between ships and noninerted barges the MVRU – 1100 serves to capture VOC’s from the barge and control vapour emissions. The MVRU – 1100 system handles up to 1100 Cu. M. per hour vapour, with a VOC removal efficiency of 99,9%. It is readily available from our warehouse in Rotterdam and can be transported by conventional means (it is the size and dimensions of a 20 feet TEU container). It can be prepared and mobilised in a matter of hours, making it an ideal partner for people planning trans-shipments in environmentally sensitive areas.

MariFlex/Damen Mobile Ballast Water Treatment

MariFlex/Damen Mobile Ballast Water Treatment


Most ship owners are expected to comply with new ballast water regulations by installing onboard Ballast Water Treatment Systems. MariFlex has also considered alternatives for those owners that may not want to retrofit a treatment system, perhaps because their ships operate on non-exempted fixed routes or their ships are so old as to make any investment in such a system prohibitively expensive. Alternatives are also required for ports that need to provide backup in the case of emergencies when ships’ onboard treatment systems fail.

For these reasons, Damen has developed a unique mobile discharge technology – InvaSave – which enables port based treatment of ballast water.
With InvaSave technology, ballast water only needs treating at the point of discharge, in contrast to most fixed onboard installations that also need to
treat at intake.
