Stena tests tech for Delta’s LNG-to-power project in Vietnam

Stena Power & LNG Solutions, a unit of Sweden’s Stena, has completed model testing of its technology for the Delta Offshore Energy LNG-to-power project in Vietnam.

Delta has previously selected Stena’s jetty-less technology for its LNG-to-power project in the Bac Lieu Province in Vietnam. The project includes an LNG terminal and a 3.2-GW power plant.

The scale model testing included the jetty-less floating terminal, the regas platform, the floating storage unit (FSU), and an LNG carrier, according to a statement by the Stena unit.

Stena joined forces with MARIN

Stena said it had completed the tests at the Maritime Research Institute Netherlands (MARIN) to verify and calibrate its computer simulations and research, ahead of construction and deployment of the assets to waters in Vietnam.

Moreover, the firm built large-scale models with up to 10m in length and in a scale of 1:30 to obtain test results with the “highest possible accuracy,” it said.

Both Stena and MARIN engineers performed a number of tests to simulate critical wave, wind and current conditions specific to local conditions in Vietnam, including 100-year cyclonic and monsoon events, it said.

Knut-Erik Johansen, engineering manager, Stena Power & LNG Solutions, said the tests “successfully verified” the performance of the technology through an extensive engineering examination with the support of engineers at MARIN.

Furthermore, he said testing took over 6 weeks in MARIN’s “large and highly reputable offshore basin to assist us to finalize design, better understand performance limits in a variety of localized wave conditions, and ultimately produce safe and effective operational procedures.”

Innovation is the key

Delta’s managing director Bobby Quintos said this new configuration for LNG regasification and storage builds on the FSRU technology, which in 2007 “everyone thought was crazy.”

“Today we have a more modular system that can easily be scaled up without having to go to drydock or shipyards. If you are not innovating in this industry, you are falling behind,” he said.

Classification society Bureau Veritas has recently also issued approval in principle for the complete LNG receiving facilities engineered by Stena for the DOE project.

Also, DNV issued a similar AIP for the jetty-less floating terminal, Stena said.
