EGCS tanker contracts give Clean Marine a boost

Jun 30 2013

News that Clean Marine was awarded a contract by Samsung Heavy Industries to supply exhaust gas cleaning systems (EGCS) for two new shuttle tankers being built for AET, has firmly put the relatively new company on the map.

The EGCS will enable the new AET vessels to comply with future legislation relating to sulphur emissions without switching to more expensive fuels. According to Nils Høy- Petersen, CEO Clean Marine, “These contracts represent a milestone for the company, and signal a growing market demand for Clean Marine’s unique and competitive multi-stream EGCS solution.”

AET has entered into a long-term contract with Statoil to operate the two DP2-type shuttle tankers to serve offshore oilfields in the Norwegian sector of the North/Barents Sea.

To operate successfully in these harsh environments, the two twin-skeg 120,000 dwt tankers will be constructed to a superior specification that exceeds any other DP shuttle tanker currently in operation, AET claimed. The tankers will be fully adapted to operations in adverse weather conditions and will be equipped with high power thrusters and engines.

Clean Marine has developed an EGCS based on the advanced vortex chamber (AVC) technology that provides particulate matter trapping efficiency. The system’s integrated fan and gas recirculation technology allows just one EGCS unit to simultaneously serve several combustion units – an important feature for vessels with many exhaust sources.

“For vessels sailing in European waters and other emission control areas (ECAs), a maximum sulphur limit of 0.1% will apply from 2015,” said Høy-Petersen. “The Clean Marine system supplied to AET will clean both sulphur oxides (SOx) and particulate matter emissions from two main engines, five auxiliary engines and three boilers. In total, a single Clean Marine EGCS unit will manage 10 exhaust sources.”

Installation of the EGCS units is scheduled to take place during 2013 and 2014, and Samsung will deliver the first tanker at the end of 2014 and the second in the beginning of 2015. Since 2006, Clean Marine has invested more than $20 mill in development of an EGCS, better known as a scrubber, for the maritime industry.

Through extensive testing in the workshop and in the field, the company’s marine scrubber has been developed into a highly flexible multi-stream EGC device for existing and new ships. The multi-stream feature allows all exhaust sources on board to be cleaned by one common cleaning unit, offering a competitive solution that is easy to operate.


One system

It is claimed to be the only system currently on the market with true multi-stream exhaust gas handling. This means that all exhaust sources on board - including boilers - are served by one common EGC unit without encountering an increase in back pressure.

This is achieved by two fans and a gas recirculation mechanism integrated into the EGC unit, which ensures that pressure at the common gas meeting point is maintained at ambient level, irrespective of the amount of exhaust fed to the system.

The company said that the AVC is another vital and unique part of the Clean Marine EGC unit. This high-speed cyclone has outstanding separation efficiency and achieves a high sulphur and particulate matter (PM) trapping efficiency at minimum cost.

Clean Marine offers a hybrid system that can operate in both open- and closed-loop mode. It differs from other systems in that it uses caustic soda in both modes, which means vessels can operate in all types of water - including low alkaline and saline water - in either mode and without loss of efficiency. Furthermore, the use of caustic soda enables the EGCS to meet the current pH limit for washwater discharges with a good margin.

Assuming a conservative $300 per tonne price difference between marine gas oil and high sulphur fuel oil - and 100% of operations inside an ECA - payback time on the investment would be about a year, the company said.

Clean Marine can offer shipowners, engine makers and shipbuilders the equipment and support needed to install an EGCS on both newbuildings and existing ships, the company said.

A Clean Marine EGCS is already operational and fully certified on the 48,200 dwt selfdischarging bulk carrier Balder owned by Klaveness. This system was fitted on board the vessel’s funnel in 2012. Between 2009 and 2011, a prototype was fitted on board Klaveness’ 84,000 dwt chemical tanker Baru.

The three major shareholders in Clean Marine – who together control some 87% of the company - have recently injected further capital. These are: -

  • Klaveness Invest - a subsidiary of Klaveness Marine Holding (KMH), which is an investor in real estate, shipping & offshore and early stage technology ventures in cleantech, oil and gas. KMH manages $500 mill in net assets and has recently made follow-up investments in Deepflex, Ingrain and Clue (parent of Clean Marine). It has also invested in and taken on active ownership roles in Prime Office Germany, NOCC and Ziebel, among others.
  • Nanga Limited - a Jersey based fund specialising in early stage technology-oriented investments. Nanga is advised by Smedvig Capital, a London based private equity firm, which manages $500 mill of private equity assets and is part of the larger Smedvig group with $1.3 bill of net assets. Current investments include Pharma, Cleantech and Nanotech in the US, Israel and Norway, respectively. These investments are affiliated with the Smedvig family and most retain Smedvig Capital as advisors. Smedvig Capital is a supportive investor staffed principally by ex strategy consultants, who take an active interest in investee firms, including providing advice and resources on finance, marketing, organisation and strategy.
  • Atlantis Vest - a diversified investment company controlled by the Rieber family, investing in industrial, shipping and real estate corporations, among others. Atlantis Vest was the main shareholder in the Norwegian food manufacturing company Rieber & Søn until it sold all its shares to Orkla earlier this year.
