Flexible and Modular “Natural Gas Operating Fleet” Concept Approved in Principle
Wärtsilä and COSCO shipping Heavy Industry Co (CHI) have announced the joint development of a natural gas operating fleet concept, and this design has now obtained Lloyd’s Register’s Approval in Principle (AiP) certificate. The development project was carried out under the terms of a memorandum of understanding cooperation signed in June 2016 between the three companies.
The aim of the concept is to offer global operators a more efficient and economical fleet design that meets current and anticipated environmental requirements according to the classification rules. The fleet comprises four vessels: a pusher tug, LNG storage barge, LNG regasification barge, and a floating liquefaction natural gas barge. The pusher tug can be used to transport the three barges.
The number and choice of units will depend on the project, since not all of the concept’s units are necessarily needed for every project. For example, the concept can be utilized to act as an LNG carrier (using only the pusher tug and LNG storage barge), or it can be used for more complex projects involving liquefaction and regasification systems (using all units).
