Newport Retrofit For Green Future With Class Go-Ahead For LNG Concept

An innovative liquefied natural gas (LNG) fuel tank system developed by Newport  Shipping for crude tankers and bulkers has gained a key preliminary class approval to  facilitate retrofits of such vessels in line with new environmental requirements to cut  maritime emissions.  

The approval-in-principle (AIP) from classification society DNV affirms the technical  feasibility of the concept for the VLCC and Capesize vessel classes, and paves the way for  it to be implemented in design work on retrofits by the UK-based ship repair and  retrofitting group.  

This marks a significant milestone for Newport Shipping, positioning it to take a leading  role in the rapidly emerging market to adapt vessel fuel systems for LNG that has seen  only a few such retrofits globally to date.  

“LNG is one of the cleanest transition fuels currently available globally and can be used  with minimum modifications to a ship,” said Newport Shipping’s managing director  Lianghui Xia. “CO2 emissions can be reduced by between 20% and 30% just by switching  to LNG without installing any other equipment.”  

Cost benefits 

As well as environmental gains, there are also significant cost benefits as LNG is much  cheaper than most fuels and there is already a worldwide bunkering network in place  offering this fuel at competitive prices, he pointed out.  

Newport Shipping’s concept is based on deck-mounted LNG tanks that can be installed  without major modifications to the vessel hull, thereby reducing installation costs, as part  of a retrofit solution using a dual-fuel engine that would also be suitable for future use of  carbon-neutral methane such as bio-LNG.  

Tank capacity, which is based on a typical ship profile and operating route, is sufficient for  a single voyage prior to refuelling.  

Conversion of the existing global merchant shipping fleet of around 100,000 vessels for  use of alternative fuels is no longer an option, but an economic necessity for shipowners  as reducing emissions will be a rite of passage for trading in a low-carbon shipping future. 

Green regulations 

The IMO has set a goal to halve greenhouse gas emissions from international shipping of  nearly 1 billion tonnes per annum, and reduce carbon intensity towards 70% of 2008  levels, by 2050.  

Furthermore, the new Energy Efficiency Existing Ship Index (EEXI) will require all existing  cargo vessels to meet stricter class limits on emissions for annual surveys performed from  1 January 2023. 

In addition to global and regional regulations, there is increasing market pressure from  charterers and banks for decarbonisation as a condition of cargo contracts and ship  finance.  
Xia believes Newport Shipping’s concept offers “a practical and cost-efficient solution” to  cut fleet emissions in the near term pending adoption of technologies for carbon-neutral
fuels such as ammonia and hydrogen, as well as battery technology, that are still some way  off commercial realisation.  

He adds that long-term payment plan over 5 to 7 years on 60% of the total cost is offered  to clients for its LNG retrofit solution. 

Newport Shipping, with a global network of 15 partner yards spanning international trade  routes in the Atlantic and Pacific regions that offers guaranteed drydock slots and fast  turnaround, is now poised to bring this LNG retrofit solution to the global shipping market.
