Gas Bunkering Made Easy, Flexible and Affordable With Yet More LNG Barge Designs

Two More Ideas on How to Provide the 'Fuel of the Future' to the Merchant Fleet

US – Crowley Maritime naval architecture and marine engineering subsidiary Jensen Maritime, has announced the development of two new liquefied natural gas (LNG) bunker barge concepts that can be fully customised to meet a customer’s unique needs. According to the parent company the new vessel concepts are exciting for several reasons, but perhaps most notably because bunker barges offers a ‘solution for the maritime industry, which is currently struggling with the decision over which to develop first, LNG infrastructure or the vessels powered by it.

The new designs come shortly after the approval in principle of Jensen's articulated tug-barge (ATB) design by classification society American Bureau of Shipping (ABS), another Jensen project. The first concept involves outfitting an existing barge with an above-deck LNG tank. This idea can be further modified to accommodate more than one type of product, if a customer, for example, has a need for multiple liquid transfers. Advantages of this design include a fast turnaround and a reduced need to invest in specialised assets if a customer has short-term LNG requirements.

The second concept is for a purpose-built, new bunker barge and is obviously the more expensive, but more refined, of the two options. Offering greater carrying capacity and improved visibility, the design features a larger LNG tank that is nestled inside of the barge. This new barge will also feature the latest safety features and efficiencies. Johan Sperling, Vice President remarked:

“We understand that customers have very different needs when it comes to LNG. Whether LNG is required for the long or short term, or in larger or smaller quantities, Jensen has a bunkering solution. We are proud to continue leading the way with LNG marine solutions.”

Jensen has identified a specific need for a developing market and is betting on the fact that, whilst larger ports may well ensure adequate LNG bunkering is built into future plans, until the fuel is in common use, smaller anchorages would benefit from a variety of cheap, manoeuvrable and flexible solutions.
