The Langh companies take environmental matters into account in their day-to-day operations, and efforts to improve the state of the world’s seas are important to all Langh companies. The environmental perspective has been at the core of the Langh companies’ operations for some time now, and the companies are a partner of the John Nurminen Foundation and a supporter of the Foundation’s Clean Baltic Sea projects.

Langh Tech’s closed loop scrubbers were installed in Langh Ship’s five cargo vessels back in 2013 and 2014. In the closed cycle, the water used to clean exhaust gases can be cleaned in a water-processing unit on board the vessel, and the resulting waste is delivered ashore in solid form. In addition to this waste, wastewater, such as latrine wastewater from Langh Ship’s vessels ms Linda and ms Aila, which sail to Helsinki, is voluntarily collected and delivered to the waste reception point at the Vuosaari harbour.

The shipping company actively seeks new ways of taking the environm...

The Langh companies have become a partner of the John Nurminen Foundation and a supporter of the Foundation’s Clean Baltic Sea projects. In addition to providing support, the Langh companies also aim to reduce environmental loads and develop solutions and methods for protecting the environment as part of their day-to-day operations. 

“The well-being of the Baltic Sea has always been at the heart of all the Langh companies. We want to support the valuable protection efforts of the John Nurminen Foundation because we believe the Foundation’s concrete measures have produced good results for the Baltic Sea. We look forward to long-term, productive collaboration,” says Linda Langh, Managing Director of Industrial and Ship Cleaning Services Hans Langh.

The John Nurminen Foundation’s goal is to achieve a visible improvement in the state of the Baltic Sea by reducing the nutrient load on the sea. To reach that goal, the Foundation’s projects involve reducing, among other things, nutrient dischar...

Langh Tech has successfully delivered a scrubber system to the Chios Navigation 50.000 dwt Medium Range product Tanker, a newbuilding from Hyundai Mipo Shipyard.

Chios Navigation has been one of the first Greek ship owners who have selected during early 2018 Langh Tech Open Loop-Hybrid ready scrubbers for their Newbuilding project in Hyundai Mipo. The system consists of a U-type multi-inlet 5 flue gas sources Open Loop hybrid ready configuration to serve a Main Engine of 7180 kW MCR power, three auxiliary generating sets and the Auxiliary Boiler, consuming totally only about 130 kW in design operating load.

At the end of April 2019, M/T DORIC COURAGE was delivered successfully from the Shipyard with sea trials confirming the high performance of the Scrubber system and its simplicity.

‘’We were looking for a Scrubber system for our Newbuilding project that would be technically simple and sound, but with qualitative elements. We favoured a provider being fully acceptable by HMD Shipyard, de...

Langh Tech and STX Offshore & Shipbuilding (STX O&S) have signed a deal concerning scrubber retrofits on seven vessels in the Polaris fleet. The four 180K bulkers and the three 300K VLOCs in the fleet will be equipped with Langh Tech’s open loop scrubbers.

The scrubber installations will be done as turn key deliveries by STX O&S. On each of the vessels the main engine and the three auxiliaries are connected to the scrubber. The scrubbers are multi-inlet type and Langh Tech delivers all the equipment necessary for a fully working open loop system. The component deliveries will start in summer 2019 and the installations will follow soon after component delivery.

Langh Tech is well established in Korea and locally represented by Regional Manager Mr. Simon Kim. “I believe that this scrubber retrofit contract with Polaris Shipping will be a great milestone for Langh Tech to cooperate with many other esteemed Korean shipping companies in the future”, says Mr Kim.

Langh Tech has secured a large deal in Greece for the delivery of 10 shipset scrubber systems for Bulk Carriers and Product Tankers.

Shipping companies Marmaras Navigation and Delta Tankers, owned by Mr. Diamantides, one of the most reputable Greek shipowners, have selected Langh Tech’s systems for their continuing fleet upgrade program. 

Marmaras and Delta Tankers belong to the first movers among the Greek ship owners, that have selected during early 2018 to entrust scrubber technology for coping with the forthcoming IMO 2020 global low sulphur cap regulations and for looking for best match options for their large variety of ship types and sizes, but also for reliable partners in retrofit projects.

The total order consists of equipping nine 92.000 dwt post-panamax Bulk Carriers and one 114.000 dwt Aframax Tanker with Langh Tech Open Loop Hybrid Ready systems, plus options for more shipsets to follow.

The scope of supply comprises of U-type scrubber towers for all the 10 vessels. In each i...

The Finnish scrubber manufacturer Langh Tech has closed its largest deal so far and will deliver SOx scrubber systems for 12 vessels owned by Dampskibsselskabet NORDEN A/S (www.ds-norden.com).

The Danish shipping company Dampskibsselskabet NORDEN A/S invests heavily in scrubber installations. Langh Tech Oy Ab will supply for retrofit four tankers and eight bulk carriers in the NORDEN- fleet with SOx scrubbers of open loop-type.

The tankers have two boilers and a total of six exhaust gas sources are connected to the scrubber. Automation enables the scrubber plant to be operated in two exhaust gas cleaning modes corresponding to 0.1 or 0.5 per cent sulphur in the fuel. This means compliance for the vessels with as well ECA and global regulations regarding SOx emissions.

The scrubbers will be of in-line type and replacing the silencers. Dry running of the scrubbers is possible, eliminating the need of bypass for the main engine. All auxiliaries will have bypass.

”NORDEN has evaluated how the...

Finland-based exhaust gas cleaning pioneer Langh Tech has explained how last week’s decision to prohibit the carriage of non-compliant fuel oil will have a material and technical impact on commercial ship operations.

In a special panel session during the Sulphur Cap 2020 conference in Amsterdam today, Langh Tech Managing Director Laura Langh-Lagerlof told delegates: “If such measures are adopted, any shipowner, operator, master mariner or chief engineer found guilty of transporting non-compliant fuels intended for burning in marine engines could face stringent financial penalties and possible imprisonment.”

Amongst the measures to reduce shipping’s carbon footprint adopted at the 72nd session of the IMO’s Marine Environment Protection Committee, which met last week in London, the MEPC approved proposals to ban the carriage of high sulphur fuels, submitting draft amendments to MARPOL Annex VI for approval and adoption at MEPC 73.

Should the amendment be adopted, any a ship without an appro...

Langh Tech has launched a new generation of water treatment systems. The system has been upgraded with new membrane technology to increase water cleaning capacity.

In 2017, Langh Tech has launched a second generation of water treatment systems, which is based on a new type of membrane filter elements. With the new elements, a 50% increase in water cleaning capacity can be reached compared to the previous elements, without increasing the size of the water treatment units.

The new type of membrane elements has been tested onboard Langh Ship’s M/S Marjatta since the first half of 2017. The testing results confirmed that the water cleaning capacity was indeed increased by 50% without compromising any other system parameters. The first set of second generation systems have already been delivered to a customer.

The second generation water treatment system is available for both exhaust gas recycling (EGR) and SOx scrubbers, and is suitable for sea water as well as fresh water systems.

Langh Tech,...

Langh Tech delivers hybrid exhaust gas scrubbers and EGR water treatment systems to 2,150 TEU container vessels on order at Guangzhou Wenchong Shipyard.

Three container vessels on order for shipping companies Eimskip Island ehf and Royal Arctic Line A/S will be equipped with Langh Tech hybrid scrubber systems and water treatment systems for exhaust gas recirculation (EGR). The newbuildings are of a new energy-efficient design developed by Deltamarin, and will be built by the Guangzhou Wenchong Shipyard in China.

The in-line scrubbers are multi-inlet installations, where the main engine and auxiliary engines are connected to the same scrubber tower. In addition, the MAN Diesel & Turbo two-stroke main engines of the newbuildings are equipped with EGR systems. EGR is a method to reduce NOx emissions to meet Tier III requirements. In the EGR process approximately one third of the exhaust gas is washed with a scrubbing unit where particles are removed from the exhaust gas before it is recycle...
