Seattle-based naval architecture firm Jensen Maritime on Wednesday revealed two new concepts for fully customizable liquefied natural gas (LNG) bunker barges.
The first concept involves outfitting an existing barge with an above-deck LNG tank, which can be further modified to accommodate more than one type of product if a customer has a need for multiple liquid transfers. According to Jensen, the 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 with a larger LNG tank that is nestled inside of the barge. This new barge will also feature the latest safety features and efficiencies.
“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 says that 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 says.
In July, a Jensen-designed concept for an ocean-going LNG bunkering articulated tug and barge unit (ATB) was granted “approval in principle” by classification society American Bureau of Shipping (ABS). The ATB is said to be particularly-suited for mobile bunkering and is also ocean-rated, meaning that it is not limited to the intracoastal waterways like many other similar types of LNG ATBs.
Jensen Maritime is a subsidiary of Jacksonville, Florida-based Crowley Maritime Corporation.
