Jensen Maritime - a naval architecture and marine engineering firm owned by Crowley Maritime Corporation - has announced the development of two new, liquefied natural gas (LNG) bunker barge concepts [pictured] that can be "fully customized" to meet a customer's unique needs.

The first concept involves outfitting an existing barge with an above-deck LNG tank. The concept can be further modified to accommodate more than one type of product, if a customer has a need for multiple liquid transfers. Advantages of this design include a fast turnaround and a reduced need to invest in specialized assets if a customer has short-term LNG requirements.

The second concept is for a purpose-built, new bunker barge. Offering greater carrying capacity and improved visibility, the design features a larger LNG tank that is nestled inside the barge. This new barge also features the latest safety features and efficiencies, Jensen says.

"We understand that customers have very different needs when it comes to LNG," said Johan Sperling, vice president. "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's designs are developed using its proprietary production engineering capabilities, which the company says makes the outfitting, construction and assembly more efficient.

"Bunker barges offer an innovative solution for the maritime industry, which is currently struggling with the decision over which to develop first - LNG infrastructure or vessels. These barges are an ideal resource for those who have LNG needs at ports not located near an LNG terminal or as an alternative to over-the-road transportation," Jensen added.
