Louisiana-based shipyard Conrad Industries Monday announced today the successful completion and delivery of the Clean Jacksonville, the first LNG bunker barge built in North America.

The Clean Jacksonville was constructed in Orange, TX, at Conrad Orange Shipyard, a subsidiary of Conrad Industries, with trials taking place in Port Fourchon, LA.

It will enter service for TOTE Maritime Puerto Rico in the Port of Jacksonville, FL, where the vessel will bunker two Marlin Class containerships operating on LNG fuel between Jacksonville and San Juan, Puerto Rico.

“Conrad has been at the helm of many firsts,” said Mr. Johnny Conrad, President and CEO of Conrad Industries, Inc.

“It is the first LNG bunker barge built in North America. It is the first time the GTT membrane system has been installed in a non self-propelled barge in the U.S. It is the first time an LNG bunker mast of this type has been built. The list goes on.”

Tim Nolan, President and CEO of TOTE says the company is looking forward to utilising the Clean Jacksonville for LNG bunkering operations

“Our partners, including Conrad Shipyard and GTT, have been critical in our development of North America's first LNG bunker barge,” he notes.

“The use of LNG as a maritime fuel results in tremendous environmental benefits – including air and water quality improvements – and this barge is the final critical component of our LNG program in Jacksonville.”

Mr. Philippe Berterottière, Chairman and CEO of GTT, added his company is honoured to play a key role in the successful delivery of this first US LNG bunker barge by Conrad.

“The broad collaboration between TOTE, Conrad, the myriad project stakeholders, and U.S. regulators led to the successful design, construction, and commissioning of this unique and ground-breaking project,” says Berterottière.

“Beyond our traditional role of designing the cargo containment and other cryogenic elements, such as the innovative REACH4™ bunker mast, GTT adapted and expanded its support services to ensure the effective training of the barge crew and the safe and satisfactory execution of the barge commissioning activities and gas trials.

“Adapting to meet the requirements and fill the gaps within this growing industry is essential to continue to develop LNG as the preferred and cleaner marine fuel of the future. GTT remains committed to that vision."

The ceremony took place at the Enoura Plant of MHI's Shimonoseki Shipyard & Machinery Works in Yamaguchi Prefecture. 

The ship's handover is scheduled for late January 2025 following completion of outfitting work and sea trials. The TRANS HARMONY GREEN will serve as a RO/RO vessel on shipping routes in Asia.

Trans Harmony Green vessel

The TRANS HARMONY GREEN is approximately 195 metres in overall length, approximately 30.6 metres in breadth, and has gross tonnage of approximately 49,500. It can simultaneously transport about 3,000 passenger cars. 

The ship's main engine and main generator engine are high-performance dual-fuel engines each accommodating LNG or diesel fuel. 

Together these engines enable a greater than 25% reduction in CO2 emissions compared to ships with the same hull and powered by fuel oil, cutting SOx (sulphur oxides) emissions to near zero, thereby helping to reduce the vessel's environmental footprint.

Study reveals achievable pathway to net-zero in Pilbara-to-Asia export trade through LNG bunker fuel

RINA completed a joint study with Pilbara Clean Fuels and Oceania Marine Energy revealing that Well-to-Wake emissions in Pilbara-to-Asia iron ore export trade route can be reduced by over 90% by 2050 through use of LNG.

Classification society RINA on Wednesday (5 June) announced it completed a joint study with Pilbara Clean Fuels Pty Ltd and Oceania Marine Energy that revealed that Well-to-Wake emissions in the Pilbara-to-Asia iron ore export trade route can be reduced by over 90% by 2050 through the use of LNG.

RINA added that Western Australia is the largest producer of iron ore in the world, with current production of over 850 million tonnes per annum, the majority of which is exported from the Pilbara region of Western Australia.

The following are the details of the study:

Key developments

- Pilbara Clean Fuels (PCF) is pursuing the development of an electrified LNG plant in Port Hedland, Western Australia aimed at producing low-carbon LNG marine bunker fuel. 

- Oceania Marine Energy (Oceania) is developing a marine fuel bunkering business using purpose-designed LNG re-fuelling vessels to be chartered from Kanfer Shipping, Norway. 

- RINA has developed an innovative concept for an LNG-fuelled 209,000 DWT Newcastlemax dry bulk carrier design incorporating pre-combustion carbon removal and hydrogen production to meet IMO 2050 Carbon Intensity Index (CII) requirements over the ship’s operating life.      

In November 2023 PCF, Oceania and RINA signed an MoU to collaborate on studies to define the commercial and emissions reduction benefits their combined concepts could deliver to ship owners and charterers for the Pilbara to Asia dry-bulk minerals export trade route. The Joint Study has now been completed. 

Study Findings

The findings demonstrate an accessible and achievable pathway to Net-Zero Emissions for LNG, on a Well-to-Wake basis, for international shipping on this trade. The study presents a flexible and commercially attractive IMO compliant marine fuel strategy to ship owners, operators and charterers amidst competing alternative fuel. It proposes a ‘Green Corridor’ marine fuels solution for the Western Australia to China bulk minerals export trade route. 

Achieving Emissions Reduction 

The low-carbon LNG plant by Pilbara Clean Fuels has the potential to initially produce LNG with emissions of less than 200kg of GHG per tonne, which can be further reduced to around 50kg/t LNG (and potentially to zero through technology improvements).  

LNG bunkering in the Pilbara region offers a substantial voyage optimization by eliminating the need to deviate to other major bunkering hubs in the region, thus significantly reducing emissions. This also reduces by 25% the emissions associated with transporting LNG over long distances, compared to LNG bunkering in other ports and ensures competitive pricing for LNG.  

RINA’s bulk-carrier ship concept features a novel propulsion arrangement which achieves a fuel saving of 12% when running on LNG at current market speeds and offers the charterer greater fuel flexibility and enhanced economic benefits by reducing LNG consumption. This can lead to lower fuel running costs, particularly when compared with traditional fuel oil. 

It provides redundancy, significantly reducing the risk of black out, and does not suffer from well-known issues like acceleration through engine’s barred speed range. The ship can also harvest the benefits from wind propulsion. 

The proposal is flexible in fuel selection and, most importantly, the use of hydrogen produced on board is on demand. This concept, which produces carbon dioxide that is captured and stored onboard, can be delivered price-competitive as it has been designed to retrofit emissions-reduction equipment in stages to suit the owners’ requirements. The design allows charterers to modify the vessels with modular hydrogen production and carbon capture and storage (CCS) equipment to meet GHG compliance as needed.  

The bunker vessel design incorporates a hybrid energy system, including an 8MWh battery, allowing for emission free operation in port. This, alongside the onboard CGR-designed process plant for vapour recovery and re-liquefaction, significantly reduces emissions and enhances operational efficiency.  

The CO2 generated from onboard pre-combustion hydrogen production can economically be integrated into the large volume CCS hubs currently being developed in the Pilbara region by various third-party proponents. 

The combination of systems and technologies allows LNG-fuelled dry-bulk carriers to significantly reduce emissions today and to comply with the IMO 2023 GHG Reduction Strategy through to 2050. 

The study concludes that by implementing this holistic combined systems approach, Well-to-Wake emissions for the Pilbara to Asia export shipping industry can be reduced by more than 90% by 2050. The reduction of GHG emissions is achieved by progressively decreasing the LNG fuel share to the engines while proportionately increasing hydrogen usage. 

This allows for staged upgrades over the vessel’s lifetime to comply with the IMO requirements for continuously reducing GHG emissions. The ship-owner to decide which path to follow to stay ahead of compliance and competition. All necessary technologies for achieving Net Zero Emissions with LNG as a marine fuel already exist and are in use, marking the first time they have been proposed in combination, demonstrating a positive path to Net Zero Emissions for international shipping.  

The Joint Study results present a significant opportunity for decarbonising shipping in the Pilbara region and beyond, contributing to global efforts to combat climate change.
