The smallest FSRUs today are around 120,000 m³. There are no small LNG carriers available that can be converted to FSRUs.
Wärtsilä has created a solution for this problem by designing a floating storage and regasification barge (FSRB) containing storage capacity from 7500 to 30,000 m³ and regasification systems. For larger storage needs multiple barges can be employed. The regasification and storage barges can be an attractive alternative to onshore satellite and bunkering terminals.
The barge can be equipped with the similar processes as the land-based solution. The process can also be split between the barge and land. This can be done, for example, by locating the LNG storage on the barge and process equipment and support facilities onshore. The barges utilise Type C-tanks for storage which eliminates the need for boil-off gas (BOG) handling.
Wärtsilä prefers to deliver the barge and necessary infrastructure onshore as a complete EPC. Wärtsilä can also provide services for total lifecycle solutions.
