EU adopts new clean fuel rules

New EU rules have been adopted to ensure the build-up of alternative refuelling points across Europe with common standards for their design and use. Member States must set and make public their targets and present their national policy frameworks by end-2016. "Alternative fuels are key to improving the security of energy supply, reducing the impact of transport on the environment and boosting EU competitiveness", said Commission Vice-President Siim Kallas, commissioner for transport. "With these new rules, the EU provides long-awaited legal certainty for companies to start investing, and the possibility for economies of scale. EU Member States requested flexibility in deploying the infrastructure. It is now up to them to develop the right national policy frameworks." Up to now, clean fuels have been held back by three main barriers: the high cost of vehicles, a low level of consumer acceptance, and the lack of recharging and refuelling stations. This is a vicious circle. With the new "directive for the deployment of the alternative fuels infrastructure", Member States will have to provide a minimum infrastructure for alternative fuels such as electricity, hydrogen and natural gas, as well as common EU-wide standards for equipment needed and user information. Access to liquefied natural...

US maritime industry leans forward on environmental stewardship

President Obama has taken action to build the foundation for a clean energy economy, tackle the issue of climate change and protect our environment. The maritime industry understands and embraces this thinking not only because it makes sense, but also as it will be essential to future viability of marine transportation. The industry continues to take a leading role in environmental responsibility and the U.S. Maritime Administration (MARAD) is helping them chart the course. With two recently released reports examining storage and bunkering options for Liquid Natural Gas (LNG) and providing vital data on natural gas emissions, US MARAD's Office of Environment and Safety is providing information the industry needs to transition to cleaner burning fuels. And by identifying potential challenges and recommending best practices and new standards, US MARAD is working to streamline the development of a transportation network that supports the integration of natural gas as a marine fuel. Another step forward was taken with approval of a $324.6 million Title XI loan guarantee to TOTE Shipholdings, Inc., a 2014 White House Transportation Champion of Change, to finance construction of two container ships that will use LNG as propulsion fuel. The US MARAD Title XI Loan Guarantee program...

MAN revises Propeller Light Running Margin Recommendation

 MAN has issued a Market Update Note providing information on the Light Running Margin (LRM) which is an important design parameter for the safe and efficient operation of a ship. The changed circumstances in the shipping industry  have led MAN Diesel & Turbo to change the recommendation for LRM.In brief, a ship should have a sufficient LRM such that:a safe and satisfactory ship speed can be maintained in heavy weather and/or with a fouled hullship accelerations needed for safe and efficient manoeuvring operations can be achieveda barred speed range can be passed quickly (which is often required also at zero ship speed, i.e. at bollard pull).  http://www.youtube.com/watch?v=C7e6RLMk5e8 Light Running Margin (LRM)To align with the rest of world’s ambitions to reduce greenhouse gas emissions, the shipping industry has developed the energy efficiency design index (EEDI) in cooperation with IMO. Combined with the steady increase in oil prices seen in the period from 2006 to 2014, the result has been improved ship designs with lower CO2 emissions relative to their transportation capacity.Lowering of the SMCR propulsion power installed is a key parameter for achieving a more fuel and CO2-efficient ship, evaluated according to the EEDI. Other parameters include lowering of the hull resistance,...
