  The 5 basic components of a Scrubber (Click here for larger view) Marco Dierico, Marine Business Development Manager, Europe, DuPont/BELCO presentation during the 2015 GREEN4SEA Forum The presentation aims to make ship operators more comfortable with scrubbing technology, that is mature, reliable and effective since it is recognized from IMO, EU, EPA. Scrubbers are not black boxes, but based on robust components used in the marine industry like pumps, heat exchangers, valves, tanks. Benefits relate to the long term savings on fuel costs and the undoubted availability of HFO over the next decades. Trends are showing a substantial price reduction for scrubbers and that passenger ships and Ro-RO ferries are driving the market with open and hybrid loop systems.    Scrubbers are robust and effective Sox abetment devices to be used for the main engines, but also for the auxiliary engines and the boilers, using water as a medium for sulphur absorption. In the end of the day, we wash the exhaust gases. Also, as a side effect, scrubbers provide the particulate removal mainly in mass and not in number.  There are five basic components for the scrubber systems. For sure, a source of water, sea water or fresh water, plus a ...

  Royal Wagenborg, the Dutch ship owner and operator, has ordered Wärtsilä scrubber systems to clean the exhaust emissions from two of its RoRo carriers, the ‘Balticborg’ and ‘Bothniaborg’. These will be Wärtsilä’s first deliveries of its scrubber systems to Royal Wagenborg. The contract was signed in March. “We have enjoyed a successful business relationship with Wärtsilä for many years and have selected Wärtsilä solutions for many vessels in our fleet. This relationship was one of the reasons that we decided that Wärtsilä would be the supplier for these scrubber systems,” according to Egbert Vuursteen, CEO of Royal Wagenborg. By installing Wärtsilä scrubber systems, the vessels will comply with the regulations covering emissions of sulphur oxides (SOx) while using conventional residual marine fuel (HFO). The Balticborg and Bothniaborg are employed on a long term freight contract with Smurfit Kappa for the weekly shipment of paper products between Haraholmen, Bremen, Sheerness and Terneuzen. These operating routes fall within the Baltic and North Seas’ Sulphur Emission Control Areas (SECA). The retrofitting of these systems will take place in the autumn of this year. The systems chosen for these vessels are Wärtsilä Hybrid Scrubbers, which enable the use of either closed or open ...

  The Ternvag, a oil/product tanker owned by the Danish company Terntank, was the most sustainable vessel to dock in Rotterdam in 2014, according to the Environmental Ship Index (ESI). Last year 1413 ships with a high entry in the Environmental Ship Index arrived in Rotterdam. In total, the Port Authority paid out €1.2 million on these sustainable vessels. Ternvag is a tanker built in 2003. At the request of de charterer – the Swedish oil company Preem – the vessel has been fitted with so-called SCR (selective catalytic reduction) for the engines. That is a post-combustion technology used to reduce emissions of nitrogen oxides (NOx). Terntank has currently commissioned the development of 4 LNG-driven product tankers. ‘In 2016 one of these ships will also be sailing for Preem. So we want to win the prize for the most sustainable vessel in Rotterdam again in 2017,’ says Tryggve Möller, director of Terntank. ‘We see the prize as an endorsement of our policy to use clean ships. Rotterdam is a sustainable port and the largest in Europe.’ Port Authority embraces ESIGranting a bonus to vessels with a high entry in the ESI is in line with Port Authority’s policy to become ...

  At an awards ceremony held on 15 April, 2015 at the PrimeServ Academy in Shanghai, MAN Diesel & Turbo SE was awarded approval in principle for its SCR system for the entire medium-speed engine portfolio fulfilling IMO Tier III regulations by the China Classification Society (CCS). Testing took place on an MAN 8L21/31 auxiliary engine with an integrated SCR system but the certificate applies to the entire medium-speed engine portfolio . The MAN-built engine is bound for a DFDS Seaways Ro-Ro vessel, the ‘Petunia Seaways’. The ceremony was attended by major ship owner companies and licensees. Goetz Kassing, Chairman and Head of MDT China, received the certificate on behalf of MAN Diesel & Turbo from Sun Feng, Vice President of CCS. “This certificate represents an important milestone in our collaboration with CCS and is of utmost importance in providing a complete IMO Tier III package solution to our customers,” said Dr. Daniel Struckmeier – Head of Emission 2016 – Senior Project Manager, MAN Diesel & Turbo. “This milestone is one of three agreed major steps in a long-term relationship with CCS. The first step has been accomplished after issuance of the first IMO Tier III EIAPP certificate for the ...

  The Finnish scrubber provider DeltaLangh Ltd that has earlier introduced a closed loop scrubber has now brought to the market also a hybrid ready open loop scrubber. Several vessels have already been installed with DeltaLangh’s True Hybrid Scrubbers, which can be operated in both open loop and continuous closed loop mode. To help the shipowners lower the environmental footprint of their vessels and fulfil the MARPOL Annex VI regulations, the company now offers also a hybrid ready solution, which can later be upgraded to a True Hybrid Scrubber without dry docking. DeltaLangh’s new hybrid ready scrubber gives flexibility for the customer – an open loop installation fulfilling all requirements, which can be later upgraded to the proven functionality of a closed loop scrubber when so wanted. DeltaLangh also gives an option with fixed price valid for 12 months for the upgrading. “This way the customer has a clear insight into the investment, which makes the decision making easier”, says DeltaLangh’s Technical Director Kimmo Henriksson. DeltaLangh’s scrubber is a result of the co-operation between Deltamarin Ltd, a recognised ship design company and Langh Ship, a shipping company that started the product development based on the need to create an economical ...

  The Liberian Registry recently entered into a partnership with USbased consultancy EfficientShip Finance (ESF) to reduce global carbon emissions, enhance fleet efficiency and competitiveness, and promote a greener Liberian fleet. In addition, each ship in the programme will be entitled to a 50 per cent annual tonnage tax discount in the first year, and up to a 25 per cent discount in both the second and third years. ESF’s partnership with LISCR offers a complete turnkey energy-saving solution for ships on a global basis with an add-on specifically crafted for Emissions Control Areas (ECAs). ESF will provide the financial capital needed for each project, and assume responsibility for technology performance and fuel volatility risk, along with the technical supervision and monitoring to perform retrofits. Owners and operators remit to ESF a proportion of the amount they save on fuel costs, or which they receive in the form of additional negotiated hire. The ESF global programme includes an optimal mix of fuel efficiency retrofit solutions for each target vessel, based on its trading pattern, age, size, speed, and consumption. For ships trading within ECA zones, the programme may include the installation of exhaust scrubber systems or the conversion of engines ...

CE Delft has prepared report for NABU which provides an economic and ecological assessment of scrubbers.  CE Delft has analysed the economic and ecological aspects of using scrubbers as a means for ships to meet the SECA fuel sulphur requirements. The study was launched in Hamburg on 13 March during a seminar organised by the German NABU (Nature and Biodiversity Conservation Union), which commissioned the study. The study focuses on the current and future market, the ecological impact of increased use of scrubbers in coastal areas and the business case for ship-owners Scrubber types Four different scrubber types are available today: 1. Seawater scrubbers (open loop) utilize untreated seawater, using the natural alkalinity of the seawater to neutralize the sulphur from exhaust gases. The negative characteristic of an open loop system is its greater energy consumption compared to a close loop system, but there is no need for chemical additives like caustic soda in a closed loop system. 2. Freshwater scrubbers (closed loop) are not dependent on the type of the water the vessel is operating in, because the exhaust gases are neutralized with caustic soda, which is added to freshwater in a closed system. Circulating water is processed after ...

  Germany's Nature and Biodiversity Conservation Union (NABU) announced the results of a study it says shows that "scrubbers are no solution to air pollution from ships." The recent tightening of the fuel sulphur limits for fuel used in Sulphur Emission Control Areas (SECAs) requires the use of fuels with a maximum sulphur content of 0.1% in these regions, or a technology that can reduce emissions to an equivalent level, from January, 1st 2015. Most low sulphur fuels are distillates (e.g. marine gasoil MGO, which are more expensive than the residual fuels that are traditionally used by ships (e.g. heavy fuel oil HFO)). Exhaust gas scrubbers, in combination with the use of HFO, have been accepted as an alternative means to lower sulphur emissions. Four different types of scrubbers are available today: Seawater scrubbers (open loop) utilize untreated seawater, using the natural alkalinity of the seawater to neutralize the sulphur from exhaust gases. Freshwater scrubbers (closed loop) are not dependent on the type of the water the vessel is operating in, because the exhaust gases are neutralized with caustic soda, which is added to freshwater in a closed system. Hybrid scrubbers give the possibility to either use closed loop or ...

  The first Wärtsilä two-stroke engine with a high pressure SCR (Selective Catalytic Reduction) system manufactured in China has been introduced. The system is fitted to a 5-cylinder Wärtsilä RT-flex58T-D 2-stroke, low speed engine produced at the Hudong Heavy Machinery Co Ltd (HHM) facilities. The SCR reactor was also manufactured by HHM. This is the first SCR system that complies with the IMO’s Tier III regulations for engine emissions of nitrogen oxide (NOx). The Wärtsilä engine with SCR is to be installed in a new 22,000 dwt multi-purpose vessel currently under construction at the Ouhua shipyard on behalf of China Navigation Co (CNCo). The ship, which is scheduled for delivery in the second quarter of this year, has been designed to allow sufficient space for the fitting of the SCR. This will enable the vessel to comply with the Tier III regulations for NOx control. The SCR system for this application has been jointly developed by HHM and Winterthur Gas & Diesel (WinGD), the joint venture company of Wärtsilä and China State Shipbuilding Company (CSSC), using a basic design concept from Wärtsilä which has been adapted to suit the particular requirements of the engine and ship. Wärtsilä has been producing ...
