South Korean shipbuilder DSME has won a KRW 411bn ($340m) deal to build an LNG floating storage and regasification unit.
In an exchange announcement the yard said the deal was concluded with a company based in Central America, without naming the buyer.
DSME said it will be delivered in June 2023.
But the yard added: "The deal will be effective after the company in Central America makes a final investment decision."
DSME said the Central America-based company will provide compensation for the costs related to the construction of the vessel if FID is not made.
South Korean press described the unit as a "floating storage regasification unit (LNG-FSRU)" and DSME provided a photo of the Q-Max-sized regas unit MOL FSRU Challenger, which it delivered to Japanese owner MOL in 2017, to accompany the regulatory filing.
Shipbuilding market watchers said the unit's price would indicate a very large or high specification regas unit.
Further details on the FSRU and the business for it are expected to emerge this month.
This week TradeWinds reported that DSME and shipowner MOL are closing in on a deal to build two giant 360,000-cbm LNG floating storage units (FSUs) for the Russian Arctic.
LNG carriers and associated units remain a focus for DSME.
In the Korea Development Bank-controlled yard's investor presentation for May, DSME estimates LNG will account for 44% of its sales for 2020, more than double the 18% expected from crude oil tankers - its next biggest vessel sector target.
