Methanol-operated Fuel Cell System Gets DNV GL AIP
A methanol-operated fuel cell system from Freudenberg Sealing Technologies has received approval in principle (AIP) from classification society DNV GL, setting the course for further testing aboard the cruise ship AidaNova as soon as 2021.Converting the approximately 100,000 commercial ships on the world’s oceans to CO2-neutral propulsion systems is one of the maritime industry's greatest challenges. Since a large part of this fleet is operated on the high seas, the range of any new propulsion systems must be able to cover vast distances.
Engine Management System Promises 10% Fuel Savings
A new patented and class-approved on-top system for intelligent engine management promises a 10% reduction in a ship’s fuel consumption with a payback period less than 18 months, says the solution's developer Frugal Technologies. To date, the system, Frugal Propulsion, has been installed and tested on four cargo ships at different shipping companies, resulting in average fuel consumption savings of 10-15% after a run-in period. For many feeder ships, ro/ro vessels, chemical tankers and ferries will correspond to 2-4 tonnes of fuel per day.In fact…
Danish Consortium Developing Ammonia-fueled Engine
Innovation Fund Denmark, the Danish investment entity, has announced the establishment of a consortium to develop a two-stroke, ammonia-fueled engine for maritime shipping. It aims to specify and demonstrate an entire, marine-propulsion system that will pave the way for the first commercial order for an ammonia-fueled vessel.MAN Energy Solutions will lead the consortium that also numbers: Eltronic FuelTech, the Danish fuel-system supplier; the Technical University of Denmark (DTU); and DNV GL, the leading classification society.
Will Customers Redefine Design and the Science of Marine Propulsion?
It is “pre-COVID ” April of 2018, and 174 member states of IMO adopt a new strategy to reduce greenhouse gases from shipping. The meetings are considered “urgent” and the target is to reduce carbon emissions in half by 2050. Prior to those “targets” shipping dealt with regulations to address SOx and NOx reductions. Most of which have resulted in limited success due to infrastructure problems and a consideration as a temporary fix.The technical world has responded with low sulfur fuels, LNG, and methanol to work towards the target.
LR Publishes Guidance on Methanol Bunkering
As stakeholders across the maritime industry assess future fuel options in support of the International Maritime Organisation’s 2030 and 2050 greenhouse gas reduction ambitions, Lloyd’s Register (LR) and the Methanol Institute (MI) have produced a Bunkering Technical Reference on Methanol, which is among the future fuels receiving close attention.The new guidance outlines the procedures required for the safe bunkering of methanol and incorporates dedicated checklists to assist shipowners/operators…
Newport Shipping Inks LNG Deal with LGM Engineering
Newport Shipping announces it will be working with global liquefied natural gas (LNG) market service provider Gloryholder Liquified Gas Machinery (DL) Co., Ltd (LGM Engineering).The agreement between the two companies was signed in February and will see LGM Engineering supply LNG solutions for Newport Shipping’s retrofit projects.In June LGM Engineering signed a contract to design and supply LNG fuel gas supply system for two 13,000 DWT chemical tankers with Jiangsu New Yangzi Shipbuilding Company Limited (YZJ).
Chinese Study Examining Methanol as a Marine Fuel
The Methanol Institute (MI) has joined a study led by the China Waterborne Transportation Research Institute (CWTRI), the think tank of the Chinese Ministry of Transport, which will consider the technical and operational requirements for the use of methanol as a marine fuel. The study is supported by methanol producers and distributors Methanex and Shanghai Huayi Energy Chemical Co., Ltd.Based on the characteristics of China’s energy and shipping industries, the study will create comprehensive guidance and policy suggestions for the use of methanol as a marine fuel…
Future Propulsion & Setting the Course to Low-Carbon Shipping
The pace at which the maritime industry transitions to low- and zero-carbon fuels will have the single biggest impact on its global carbon footprint, more than predictable shifts in commodity demand, advances in ship technology and operating practices, or new designs.That is a key finding of a comprehensive new report, Setting the Course to Low-Carbon Shipping, from the American Bureau of ShippingThe report looks at the decarbonization of shipping via two distinct scenarios: a ‘standard’ scenario…
Stena Bulk Presents Fuel-efficient Tanker Prototype
Swedish shipowner Stena Bulk unveiled a prototype of its next-generation environmentally friendly product and chemical tanker, the IMOFlexMAX, engineered to reduce greenhouse gas emissions by more than 25% compared to typical modern product tankers.The vessel, designed by naval architects at Stena Bulk's sister company Stena Teknik, is a further development of the company's IMOIIMAX design currently in operation, but with several notable additions. The vessels will be equipped with Flettner rotors and solar panels to harvest energy from wind and sunlight.

VTT Studying Bio- and Waste-based Oils for Ships
Researchers looking for an ecologically and economically sustainable way to replace fossil fuels are exploring how suitable fuel oils made from biomass and waste plastics are for power plants and ship diesel engines.Internal-combustion engine power plants use natural gas or heavy fuel oil in diesel engines. In order for large diesel engines to be environmentally sustainable both on land and at sea, it is necessary to find bio- and waste-based alternatives to fossil fuels. These…
Lubrication Selection Fundamentals
As an operator of vessels, you understand that lubricants play an important role in helping you achieve your operational objectives. Yet, finding the right one can be overwhelming since there’s an almost unlimited number of different lubricant formulations. An understanding of lubrication chemistry, performance expectations and operational objectives will help you select a lubricant that will improve operations and lower your overall costs.Lubrication benefitsThe basic function of a lubricant is to reduce friction by separating interacting surfaces.
CMB Targets Zero CO2 Emissions by 2050
Belgium-based shipping group Compagnie Maritime Belge (CMB) announced it will invest in new technologies that will enable it to operate a zero carbon fleet by 2050.The 125-year-old firm, which operates a fleet of bulk carriers, containerships and chemical carriers, said it has already begun offsetting its CO2 emissions to have net zero CO2 emissions from 2020 by supporting certified climate projects in developing countries and acquiring high quality Voluntary Carbon Units (VCU’s) in Zambia (agro-forestry…
