When Efficiency Does Not Help Sustainability

Copyright Andriy Sharpilo/AdobeStock

My brother and I had a discussion about methanol where we concluded that methanol is a promising sustainable liquid fuel for transportation devices when batteries cannot do the job. While Methanol is initially not carbon zero, as long as we focus on developing zero carbon electrical energy, eventually we can produce zero carbon green methanol. Once there is plentiful green methanol, existing methanol vehicles will automatically become zero carbon transportation.The core argument…

As maritime faces transcendent changes in regards to decarbonization, digitalization and automation, innovators from inside and outside of the industry will be challenged to deliver new applications and technologies with increased speed and frequency. Sitting at the center of the innovation storm are classification societies, and earlier this year the American Bureau of Shipping (ABS) became the first classification society to incorporate goal-based standards throughout major rule sets, enhancing its ability to handle the increasing flow of novel concepts and new technologies.

Aussie Pumps Releases New Bronze Pump

Source: Aussie Pumps

Australian Pump Industries (Aussie Pumps) has launched a 4-inch NiAl bronze self-priming pump with hydraulic drive.The new pump, called the B4XRA/B HYD34, produces 2,200 lpm and can operate at up to 42psi. It can also lift water through a vertical suction lift of 6m.Aussie Pumps Chief Engineer John Hales said: “The pumps self-prime. You can see from the big tank that’s designed into the body. When the product is properly primed it will have no trouble fulfilling its suction responsibilities in any installation.”“Most vessels today have hydraulic capabilities.

Future Ships: Picture Perfect

(Image: Siemens)

Big data, advanced computers and AI are allowing vessel designers to prepare models that leave essentially nothing to chance.“Lastly, it may be of considerable importance to form from the draught a block model of the vessel from which a still more accurate judgment may be formed of the fitness and beauty of the body. And should any defect be discovered, farther alterations must still be made, till the draught and the model are perfectly approved of. These different alterations and repeated calculations may appear very tedious…

Demand for data that can inform strategies for asset management and performance monitoring is driving the wider adoption of digital tools in shipbuilding. Vessel designers are increasingly able to employ a software-driven approach that creates efficiencies and satisfies compliance.Shipowners want visibility on assets over their lifecycle, and as the era of planned maintenance routines gives way to predictive interventions, shipyards are turning to 3D models to create digital twins…

Designing Ships Around Emissions: The Right Path or a Fork in the Road?

© xtock / Adobe Stock

When discussing ship design, the maritime industry has been tossing around a number of new terms and definitions. Sustainability, alternative fuel “ready”, digitization and lifecycle are a few of the terms becoming more commonplace amid the industry’s search for zero emissions solutions. As IMO MEPC 80 meetings push emissions reduction to meet “well to wake” requirements, we will learn much of the challenge is tied to energy and infrastructure ashore. Electrification and the development…

Technical inquiries to SRC Group ramped up after it received Approval in Principle (AIP) for a concept which ‘reinvented methanol fuel storage’ on board ships. Delivering the answers has seen technical talk converting into project discussions        ‘Green’ methanol has the ability to one day run vessels almost emission-free, and commercial shipping increasingly investigates. Derived today principally from natural gas, methanol is nonetheless available, relatively easy to handle and predictable.

Emirates Shipping Line (ESL) reports that it has cut 20% emissions on 75% of its fleet using a multi-prong approach of equipment technology and operational technique.A central aspect of the program involved a re-design of ESL’s vessels' propellers. In collaboration with designers from Mecklenburger Metallguss GmbH (MMG), ESL and the Peter Döhle group jointly developed and installed upgraded propellers on each ship. The use of these propellers reportedly yielded a significant improvement in overall flow and efficiency.

If the global commercial fleet reduced its speed by 10%, it would reduce underwater radiated noise by 40%, but nothing’s ever that simple.The main thing holding the shipping industry back from reducing its underwater radiated noise (URN) is not a lack of appropriate technology. It’s argued that many of the technologies being implemented today to reduce fuel consumption also reduce noise. So, the noise reductions could essentially come at no net cost to the shipowner, but there’s a lack of regulation and a lack of targeted incentives…
