Study finds substantial increase in nanoparticles in air as it crosses the Baltic Sea; shipping emissions responsible for about half
November 23, 2015
A study by a team of international researchers has found that air crossing over the main basin of the heavily ship-trafficked Baltic Sea shows a “substantial” increase in the number of 50–400 nm particles (50–400N). An open-access paper on their work is published in the journal Oceanologia.
The researchers evaluated 10 months worth of data (September 2009 to June 2010) of atmospheric aerosol particle number size distribution at three atmospheric observation stations along the Baltic Sea coast: Vavihill (upwind, Sweden); Utö (upwind, Finland); and Preila (downwind, Lithuania).

(CMAL is currently holding a naming competition for the ferry.)
National Marine Manufacturers Association endorses use of isobutanol in marine fuel market
June 18, 2015
The National Marine Manufacturers Association (NMMA) has identified biobutanol as a suitable and safe alternative biofuel to ethanol. The research and subsequent resolution to move forward formally with butanol as an industry-wide biofuel alternative comes as the industry focuses on addressing the congressionally-mandated Renewable Fuel Standard (RFS) requiring 36 billion gallons of renewable fuel to be blended into the gasoline supply by 2022.
Methods to increase renewable fuels in the gasoline supply have primarily focused on ethanol—specifically fuel with a higher blend of ethanol such as E15 (fuel with 15% ethanol). Multiple reports show that ethanol blends greater than 10% can cause significant damage to marine engines. As a result, the marine industry has explored biobutanol fuel blends with promising results.

March 25, 2015
|Azipod D. Click to enlarge.|
ABB has introduced a new offering, Azipod D, to its line of Azipod marine electric propulsion systems. This new product will allow a wider range of vessel types to benefit from the proven reliability and flexibility that have made Azipod the leading propulsion system across numerous ship types.
Azipod Propulsion is a gearless steerable propulsion system in which the electric drive motor is in a submerged pod outside the ship hull. A ship with Azipod Propulsion does not need rudders, long shaftlines or stern transversal thrusters. This new Azipod D provides designers and ship builders with increased design flexibility in order to accommodate a wide range of hull shapes and propeller sizes, as well as simplicity of installation. The Azipod D requires up to 25% less installed power. This is partly due to the fact that the new hybrid (air and water) cooling helps reduce the thruster’s weight and directs more power toward propulsion of the ship, not cooling requirements. The performance of the electric motor is increased by up to 45%.

Successful vessel test for new Voith Linear Jet; more efficiency in 20-40 knot envelope
February 06, 2015
|Comparison of Voith Linear Jet with other propulsors. Click to enlarge.|
The Voith Linear Jet is a new propulsor combining the best properties of conventional propellers with the best properties of conventional waterjets. The VLJ is a fully submerged, custom-shaped deceleration/acceleration nozzle with a stator section aft of the rotor. The stator section cancels rotor-induced swirl, and through that, optimizes the acceleration of the jet stream and the rudder inflow. The submerged position eliminates the requirement for a long inlet tunnel resulting in linear in- and out-flow and low marine growth sensitivity. The resulting benefits of this natural flow path without redirections are increased efficiency and reduced noise and vibration levels.

At the current allowable levels of sulfur in marine bunker fuels, pollutant emissions (particulates, black carbon, NOx, SOx, and CO2) from projected increased ship traffic transiting the US High Arctic could increase from 150% to 600% (depending upon the pollutant) above 2011 levels by 2025, according to a new working paper just published by the International Council on Clean Transportation (ICCT).
The new study is based on a study—“10-Year Projection of Maritime Activity in the US Arctic Region”—completed last month by the ICCT for the US Committee on the Marine Transportation System (CMTS) and submitted to the White House as part of the deliverables for the 2013 National Strategy for the Arctic Region and its 2014 Implementation plan. That study provided estimates of vessel traffic (numbers of vessels and transits) based on modeling of current vessel activity patterns, growth potential, and vessel projection scenarios, including diversion from other routes, and oil and gas development. The study found the potential for 1,500–2,000 Bering Strait transits in 2025, a three- to four-fold increase from 440 transits in 2013 (based on the medium-growth scenario).
New research collaboration tackling ship hydrodynamics and fuel efficiency
January 23, 2015
A new research collaboration between A*STAR’s Institute of High Performance Computing (IHPC), Sembcorp Marine Ltd, University of Glasgow and University of Glasgow Singapore (UGS) aims to improve make a ship’s hydrodynamics and energy efficiency. The four organisations signed a memorandum of understanding (MoU) to collaborate and develop new hull designs for large ocean-going vessels.
Under the three-year MoU, IHPC, Sembcorp Marine Ltd, University of Glasgow and UGS will use computational modelling and visualisation technologies to design vessels with improved hydrodynamics for better fuel efficiency. In addition, they will collaborate and innovate on features to reduce harmful exhaust emissions and discharges by enhancing the vessel’s scrubber and ballast treatment systems. Currently, maritime transport carries about 90% of all international trade and accounts for 3% of global greenhouse gas emissions.
Haldor Topsøe ECO-Jet wins award; reducing soot, HC and heavy metal emissions from ships powered by bunker fuel
December 05, 2014
Haldor Topsøe A/S has won the Danish Engineering Product Award 2014 (in Danish Ingeniørens Produktpris 2014) for its new ECO-Jet solution. The product is a newly developed catalytic process capable of reducing emission of harmful substances such as soot, hydrocarbons and heavy metals from ships powered by bunker fuel, also known as fuel oil.
Particulate filter systems are developed for diesel engine exhaust with a relatively low sulfur and ash content. These systems can not be employed for maritime engines fueled with bunker oil, which contains very heavy hydrocarbons and polyaromatic compounds and is heavily contaminated with compounds which do not burn and end up as ash in the exhaust.
MHI completes development of next-generation LNG carrier; apple-shaped tanks and hybrid propulsion
November 29, 2014
|Sayaringo STaGE. Click to enlarge.|
Mitsubishi Heavy Industries, Ltd. (MHI) has completed development of the “Sayaringo STaGE,” a next-generation LNG (liquefied natural gas) carrier. The Sayaringo STaGE was developed as a successor to the Sayaendo (earlier post), the company’s LNG carrier evolved from carriers with Moss-type spherical tanks that offer a high level of reliability. (Moss-type LNG carriers use independent spherical cargo tanks supported by a cylindrical skirt integrated with the hull and covered with a hemispherical steel cover attached to the main deck.)
While the Sayaendo (sayaendo = peas in a pod in Japanese) features a peapod-shaped continuous cover for the Moss spherical tanks that is integrated with the ship’s hull, in lieu of a conventional hemispherical cover, the new Sayaringo (ringo being the Japanese word for “apple”) STaGE adopts apple-shaped tanks, resulting in nearly a16% increase in LNG carrying capacity without changing the ship’s width. Further, a hybrid propulsion system has boosted fuel efficiency by more than 20% compared to the Sayaendo (and more than 40% vis-à-vis earlier carriers).
