Classification society Lloyd’s Register (LR) on Friday (17 November) said in collaboration with SDC Ship Design and Consult, it has developed a new concept for the use of ballast water tanks in place of cofferdams around methanol tanks, allowing ship operators more space for methanol fuel technology. 

For retrofits of methanol technology on existing ships, the development is expected to enable shipowners to convert their vessels without a loss of valuable space, by removing the requirement for cofferdams around fuel tanks as required by MSC.1/Circ.1621.  

Cofferdams are large spaces used to prevent contents from adjacent tanks leaking directly to other areas. The need for this space either increases the size of a vessel or takes space that could be better utilised, and correspondingly increases a ship’s fuel consumption.  

The innovation is expected to greatly reduce the likelihood of cross contamination by enhancing tank boundaries with thorough welding processes, increased quality controls and additional safety measures. 

The concept is expected to allow for an efficient vessel design for a wide range of ship types and will see LR generally accept the use of ballast water tanks in place of cofferdams, as required by IMO interim guidelines for the safety of ships using methyl/ethyl alcohol as fuel.  

The innovation is relevant for both new constructions and conversions, with defined design requirements set under a project specific design and arrangement process. The collaboration followed a retrofit project with SDC Ship Design in which LR and SDC jointly developed the concept.  

Colin Rawlins, Strategic Business Partner and Senior Representative for Germany, Lloyd’s Register, said: “LR is pleased to unveil its innovative concept for the installation of methanol fuel tanks without the requirement for cofferdams. This development will allow both new construction projects and conversions to utilise space otherwise taken up by cofferdams to install methanol as fuel technology, thereby helping to accelerate the maritime energy transition with easier adoption of alternative fuels such as methanol.”

Michael Waechter, SDC Managing Director, said: “It must be in everyone’s interest to find simple and therefore efficient solutions for the implementation of alternative fuels in order to speed up the transition to net-zero shipping. These solutions must not compromise safety in any way and should be based on the respective physical/chemical properties of the fuels. The developed solution helps us to accommodate more methanol capacity in less space and thus increases the efficiency of the ship. However, further efforts are needed at all levels to make alternative fuels more commercially attractive.” 

Manuel Ortuño, Global Manager Ship Structures Specialised Ships, Lloyd’s Register, said: “LR and SDC have developed this concept to help overcome the difficulties the industry faces with the application of the IMO Interim Guidelines. This innovation will provide an equivalent level of safety without the need for cofferdams, thereby allowing for efficient ship design and conversion opportunities.” 

Lloyd’s Register recently published a report on Engine Retrofits that evaluated the state of technology, integration and compliance, alongside the business case for retrofitting vessels. One of the key challenges with retrofits identified by the study is system integration, with significant issues such as accommodation for larger fuel tanks, space for fuel preparation equipment and ensuring safety measures are in place, to rapidly retrofit the existing fossil fuel flee

Singapore: GCMD develops calculator to explore IMO GFI-linked pricing system

The Global Centre for Maritime Decarbonisation (GCMD) on Tuesday (15 April) introduced a free cost and compliance calculator that has been developed by its team based on the newly approved greenhouse gas (GHG) emissions pricing framework by the Marine Environment Protection Committee during its 83rd session (MPEC 83). 

The calculator will help maritime stakeholders explore how the two-tiered, GHG Fuel Intensity (GFI)-linked pricing system could impact operational costs.

GCMD said the buzz around International Maritime Organization's MEPC 83 and the newly approved GHG emissions pricing framework has been intense — and understandably so.

“To help make sense of it, our CEO Prof. Lynn Loo started with handwritten trajectory calculations to break down the core workings,” it said in a social media post. 

“Building on that, our team has developed a simple, accessible cost and compliance calculator to help you explore how the two-tiered, GFI-linked pricing system could impact operational costs.”

The calculator is just one input—its results should be considered alongside other economic and operational factors to inform commercial decisions.

The tool covers covers heavy fuel oil (HFO), liquified natural gas (LNG), B24 biofuel, e-ammonia and bio-methanol.

“Whether you're assessing fuel options, planning newbuilds, or just trying to get a feel for what this might mean for your operations — this tool offers a useful first-cut view. For added clarity, we’ve included the workings on the side so you can trace the calculation process,” GCMD added.

Maritime Week Americas to assess how US policy changes will impact bunkering

Maritime Week Americas is coming to the United States amid the trade mayhem and turmoil and will try to assess how US policy changes will impact the day-to-day business of shipping and bunkering, as well as the maritime industry’s shift towards a zero carbon future.

President Donald Trump has wasted no time in overturning the status quo and injecting massive uncertainty into every aspect of world trade, said ship.energy.

With the dust still nowhere near settling, there is no telling when the chaos will end or what the energy, shipping and bunker markets will look like in a month or year from now.

Llewellyn Bankes-Hughes, CEO of ship.energy, founder and organiser of Maritime Week Americas, said: “There is no doubt that the conversations at MWA25 will be livelier that ever as delegates battle to come to terms with a completely new world order. What all this turmoil means to shipping and bunkering, let alone to global, regional, and national economies, will be the question that everyone joining us in Tampa will be asking. Hopefully by the end of the event we will have some answers.”

Maritime Week Americas is always where the key questions are raised and answers are sought. With vigorous debate and frank discussion, well over 250 bunker buyers, suppliers and traders will gather in Tampa for an intense week that includes training, the MWA25 Flagship Conference, and – as always – some unmissable networking.

MWA25 will look at shipping and bunker markets throughout North, Central and South America and the Caribbean, examining traditional bunker markets and the ‘new’ fuels whose take-up is rapidly picking up pace. But can the same be said now for the United States?

Traditional marine fuels are still the mainstay throughout the Americas. The conference will examine fuel quality and quantity issues and take a close look at what is happening in some of the continent’s more active markets, such as Peru and Panama.

There LNG is now a mainstream marine fuel as its availability grows throughout the Americas, with Panama among the newest supply hubs. But is there potential for a backlash over LNG’s green credentials?

Biofuels are also on a fast upward trajectory, with Brazil and other countries now leading the way. But while LNG and biofuels look set to play a key role in fuelling ships for the foreseeable future, other fuels, such as methanol, ammonia and hydrogen may not be too far behind. These, and the full range of alternative fuels will be examined in depth during the MWA Conference.

More ports are now beginning to appreciate the environmental benefits of making shore power available to visiting vessels, with some – such as Miami – currently assessing the benefits of installing electric power facilities and others – such as Seattle – already planning to mandate cold ironing for cruise ships visiting the port. At the same time, more electric-powered vessels are beginning to appear, with Canada’s Montreal and Vancouver currently leading the way with new electric ferries. Meanwhile, the world’s biggest electric-powered ferry is expected to start operating between Buenos Aires in Argentina and Colonia in Uruguay by mid-2025.

For the first time, Maritime week Americas will include an entire session focused on Jamaica, an island determined to revitalise and boost its shipping, maritime and bunkering activities.

As always, MWA25 will feature some exciting networking events, designed to highlight the new venue and to ensure that the delegates take every opportunity to network.
