Moving Ahead Powerfully

The layout of ship propellers is a balancing act between optimal power conversion and the avoidance of unwanted cavitation effects, which can result in damage to the propeller structure and higher noise levels. MAN Diesel & Turbo in Frederikshavn, Denmark, is using the computational fluid dynamics (CFD) simulation solution STAR-CCM+ from Siemens PLM Software to model cavitation and optimize ship propellers. Two mid-size container ships of 8,500 TEU – CSCL Europe and CSCL America – will be upgraded by retrofitting a efficient Kappel propeller.

Emissions Regulations: 'It's Not Easy Being Green'

Nor is it getting any easier to understand when, how and why to comply. Whether your marine operation is a major corporation or a family “mom and pop” company, the type of fuel you now burn or for that matter what emanates from your stack each day after the burn has now become a major source of confusion. As Kermit the Frog once said, we will now know what its like to be green. Some believe the discussion is a new subject. It is not. Those of us that work the oceans, rivers and sounds for a living always had a concern of how much fuel we burn and what the quality of that fuel was.

Eco Ships: The New Norm for Top Tier Ships

The high average cost of bunker fuel over the past decade led to increased interest in fuel efficiency. Shipowners have a difficult time demanding higher rates in response to cost increases. This makes any savings they can realize on operational and fuel costs critical. Fuel costs account for about 70 to 85 percent of the cost of running a ship, so savings realized in consumption go to their bottom line. Ships which travel at a higher speed, such as gas carriers and container vessels, see the highest percentage adaptation.

A Case for Propeller Guards & Cutters

As I was preparing for Thanksgiving dinner I put on Indiana Jones and the Last Crusade. While Indiana Jones and Doctor Elsa Schneider were being chased by the Brotherhood of the Cruciform sword through Venice and their boat was neatly shredded by the propellers of a larger vessel, it had me thinking of how much propeller technology has changed over the years. And how hopefully Indiana’s boat did not actually damage that vessel’s propeller. Recently an article passed though my news feed about the first 3D printed propeller. This is indicative of the direction the industry is taking.

Inside Modutech Marine’s Work Boat Medium

The U.S. Navy has some spectacular vessels, from submarines to high speed RIBs. They also have dedicated ports and support facilities worldwide. A practical reality of all of this is that the Navy requires efficient and handy boats to support the warhorses. To meet this requirement John Myers of the naval architect firm Hockema & Whalen and Associates have developed a 30 by 15-foot tug with a 5.5-foot draft. Currently the Navy has 24 of these tugs, designated Work Boat Medium, on order from Modutech Marine Inc. of Tacoma, Wash.

Emissions Regulations Present Strategic Opportunity

The marine industry as a whole is responsible for about 2.5 percent of global greenhouse gas emissions. Shipbuilders and fleet owners have spent the last two decades adjusting to shifting emissions regulations since the introduction of the MARPOL Convention 1997 Protocol, which included specific regulations for the reduction of air pollution from marine vessels. Since then, there have been additions and amendments to ensure that the industry is doing its bit to better support the environment, with the latest regulation pulling forward lower caps in global emissions.

A New Breed of Tug

When markets expand niches are created, goes the logic. For builders of tugs, that market is “floating gas” and the expanding use of liquefied natural gas, or LNG, as a fuel. In support of LNG, there’ll be more oceangoing tug duty — the new floating storage and regasification units, or FSRUs, mean busier LNG carriers, and LNG cargo owners have an interest in tug escorts that share their “carbon footprint”. Still, new emissions rules offer ways to keep using refinery products, and the work of master tug designers suggests the new breeds of tugs are about more than fuel.

Supporting Silent Ships

Have you ever had problems talking to someone in a noisy environment such as a busy restaurant? The same happens to marine animals, which use sound to sense and interact with their environment: for communication, navigation, finding prey and even for self-defence. High ambient noise levels, which include a contribution from shipping, have an adverse impact on marine life. The world’s oceans are becoming increasingly noisy. While the size of the global commercial fleet more than doubled since the 1960s, anthropogenic noise in the oceans has actually increased eightfold.
