Why Ammonia Is the Fuel of the Future for Maritime Shipping

Commercial maritime shipping has a fuel problem. While the industry has cemented its position as the essential piece of the global supply chain—moving more than 80% of all international goods by volume—its dependence on carbon-emitting fuel has come with a high cost.Maritime shipping is responsible for roughly 3% of all greenhouse gas emissions, according to the International Maritime Organization. The longer that ships continue to run on carbon-emitting fuel, the harder it will be to reach net zero emissions by 2050 and to prevent the worst damage predicted by climate scientists.

Germany-based inland waterway shipping firm HGK Shipping has signed a memorandum of understanding with Hydrogenious LOHC Maritime and Hydrogenious LOHC Technologies to work on developing a scalable solution to make hydrogen available as a source of energy on a large scale. The technology is based on hydrogen, which is bound in a liquid carrier (LOHC, liquid organic hydrogen carrier). The partners are planning to develop a demonstration vessel by 2028 and then put it into service…

Nutrient removal in membrane bioreactor wastewater treatment systems is the future. Rederi AB Gotland acts now for both savings and the sake of our seas. Rederi AB Gotland, Sweden’s oldest passenger shipping company, has chosen Evac products to equip its new LNG-fueled passenger and cargo vessels which will ply Baltic Sea routes. Each vessel will carry approximately 1,700 passengers and crew. And since the Baltic Sea is classified as a Special Area (SA), the new vessels will also carry the most state of the art nutrient removal system.

Gas reforming company Gas2 said it has achieved a second milestone at its 3 bpd (barrels per day) Wilton Research Center pilot plant in Teesside, U.K. as it develops a new generation of natural gas-to-liquids (GTL) process technology which has the potential to deliver lower cost solutions for small scale plants. By successfully commissioning and starting-up the Fischer Tropsch (FT) reactor, using syngas produced in the syngas reactor, the company has produced hydrocarbon liquids.

With popular television shows such as “Modern Marvels” and “How It’s Made” showcasing larger structures and assemblies being designed, built and often welded, it’s important that manufactures and builders be equipped to handle such construction landmarks. In the last twenty-five years, huge construction projects have gone underway and some have since been completed with more and new projects to start every day. Such projects as the Oakland-San Francisco Bay Bridge, Burj Khalifa in Dubai and Virginia Class Submarines were and are some projects driving the welding industry.

The U.S. Naval Research Laboratory (NRL) is developing the chemistry for producing jet fuel from renewable resources. Refueling U.S. Navy vessels, at sea and underway, is a costly endeavor in terms of logistics, time, fiscal constraints and threats to national security and sailors at sea. In Fiscal Year 2011, the U.S. Navy Military Sea Lift Command, the primary supplier of fuel and oil to the U.S. Navy fleet, delivered nearly 600 million gallons of fuel to Navy vessels underway, operating 15 fleet replenishment oilers around the globe.

Air Emission Regulation Update

Mikael Troberg of Wärtsilä

In March this year, The U.S. Environmental Protection Agency proposal to designate waters off the North American coasts as an Emission Control Area was adopted by IMO, the International Maritime Organization. The North American ECA is a key part of a comprehensive EPA program to address harmful emissions from large ships. Which are the time schedules of upcoming emission regulations? How are marine engine manufacturers preparing for the tighter air emission limits being adopted? Henrik Segercrantz explores.

Alternate Propulsion Plant Using Fuel Cell Technology

Since the marine industry continually laments restocking engineering talent to power its future, Maritime Reporter & Engineering News decided to hit the road and find where the future lies. Institute. Presented here is the recent work of two Webb upper classmen, Dusty Rybovich and Michael Cariello. It is our responsibility as engineers to design a better world. Currently, the world is moving toward more environmentally friendly, or “green,” technologies with a focus on reducing emissions and finding more efficient sources of energy. Traditional marine diesel propulsion relies on the combustion of finite sources of energy and is ultimately an inefficient generator of electrical power and also creates harmful emissions.

As SOLAS Deadline Nears, More Composite Use is Expected

Composites have been utilized in various applications in the shipbuilding industry in order to meet countless requirements of shipyards and ship owners. Composites have found their way into areas such as hull design for smaller vessels to modular bathroom units on larger vessels. Research and development with composites has also created Trevira fabric. Composites continue to evolve along with the shipbuilding industry, and one should expect to see more wide spread use of this material in years to come. In order to better understand composites one must review the creation of this modern material, and then one can examine the uses of this product. The general definition for composite material is the combination of two or more materials in order to create a completely new material.

EPA – Cleaner Air Emissions from SI Ferries

A on the Staten Island ferry will not only be free, it will be clean - and that's just the beginning of a region-wide effort to clean up the ports in the Northeast, according to the U.S. Environmental Protection Agency (EPA). EPA today joined the Port Authority of New York and New Jersey, the New York City Department of Transportation and the U.S. Army Corps of Engineers in highlighting the successful clean up of diesel emissions from one of the ferries that transports 19 million people to and from Staten Island each year. Retrofitting the ferry, Alice Austen, has already cut emissions of 16.5 tons of nitrogen oxides (NOx) per year and slashed particulate matter (PM) by 25 percent.

MEP Nominated For Seatrade Award

Marine Environmental Partners, Inc. (MEP), a Fort Lauderdale-based developer of ballast water and wastewater treatment systems, has been nominated for the 2003 Seatrade Protection of the Marine and Atmospheric Environment Award. MEP's water treatment technology utilizes a patented MariSan electro-chemical process that prevents invasive aquatic species found in ballast water from being introduced into non-native marine ecosystems. MariSan meets and exceeds stringent environmental regulations including pending IMO, U.S. Coast Guard and other regional regulations. By eliminating the use of chemical additives, the MariSan system is environment-friendly…
