Decarbonizing Marine

Clean propulsion through LNG and hydrogen Fuel Gas Supply Systems (FGSS) and the shore to ship bunkering infrastructure for refueling. Exhaust gas recirculation and capture systems directly reduce emissions, while air lubrication, waste heat recovery solutions and steam turbines reduce energy consumption.

Applying our rotating equipment expertise

Air Lubrication System

Air lubrication technology is based on blowing micro air bubbles out under the hull of the vessel. The air bubble distribution across the hull’s surface, reduces the resistance generated between the ship’s hull and the water, thus generating an estimated fuel saving of up to 7-10%. Air Lubrication Systems can be used in all types of vessel operations.

ChartMarine has combined in-house compression expertise and proprietary partner air distribution box design technology to create the most efficient air lubrication system with the smallest footprint.

  • Available for new builds and retrofits
  • Applicable to the widest range of hull forms
  • Minimized energy consumption in operation
  • Negligible additional resistance when not deployed
  • Low noise
  • Intelligent control system compatible with Howden Uptime
HV-TURBO compressor

Exhaust Gas Recirculation

Exhaust Gas Recirculation (EGR) is a method to significantly reduce the formation of Nitrogen Oxides (NOx) in marine diesel engines. By using this technology, vessels are able to meet with the IMO NOx Tier III standard emission limits applying to the North American and United States Caribbean Sea as well as any new Emission Control Areas.

The EGR compressor is a single-stage turbo-compressor with oil lubricated bearings, direct driven with an asynchronous motor and a variable frequency drive. The design features the unique flow optimization mechanism, utilizing inlet guide vanes to optimize efficiency for a given motor rating.

The core compressor features an impeller, milled from a solid, forged piece of duplex stainless steel with an optimal weight/strength ratio. All parts in contact with the medium are made of corrosion resistant steel. The compressor is equipped with a contact free carbon floating ring sealing to ensure that no exhaust gas can escape from the compressor casing.

The EGR turbo-compressor is available in two sizes:

  • EGR-10, range from minimum 1,02 m3/s to maximum 3,60 m3/s
  • EGR-22, range from 1,80 m3/s to maximum 6,33 m3/s

Below Deck Ventilation

​Howden offers a wide range of axial fans to supply and process air within critical and demanding processes across multiple industries.

We have been at the forefront of axial fan technology since the earliest days of its development, and we continue to lead the world in raising energy efficiency, improving reliability and reducing lifetime costs for our customers.

Many of our fans are serving in applications where durability and performance is key to continued operations. Our substantial installed base and long customer relationships bear witness to the high-quality finishing of our fans and excellence in engineering design. This is carried through from bespoke fans for power and mining to standardised fans supporting ventilation in transport tunnels and air provision in light industrial settings.

Axial Fans

Waste Heat Recovery System

​Our steam turbines have a rich history. These 'Dampfturbine' were originally designed and manufactured by Kuhnle, Kopp & Kausch AG - formed in 1899 and have subsequently been manufactured under the name Siemens Turbomachinery Equipment.

A unique feature of these steam turbines is the way that they have been designed to be modular, so that they can be connected in a huge different number of combinations. This makes them incredibly flexible and therefore able to fit with a wide range of customer requirements.

Steam Turbines are designed to turn energy from fluid onto the rotor, and our products are considered the most economical and flexible turbines that you can get. The steam turbines can be used as a generator drive for power generation, or as a mechanical drive for your rotating equipment such as compressors and pumps.

Chart complete shore to ship bunkering terminals include cryogenic storage tanks, vacuum insulated piping, vaporization and loading arms.

Cryogenic storage tanks are shop built and other components typically supplied as modules, often skid mounted. This reduces construction time at site and allows future capacity expansions to be incorporated into the initial plant design.

Chart cryogenic tanks provide high thermal performance with extended hold times to deliver significantly lower lifecycle costs versus standard tanks.

Chart vacuum insulated pipe decreases heat leakage by 90% and offers a functional life 10x longer than mechanically insulated pipe.
