PTSC’s visit is expected to provide LS Eco Energy with an opportunity to realize its cooperation plans for expanding its submarine cable project in Vietnam and Southeast Asia. Together with PTSC and its subsidiary LS Marine Solution, LS Eco Energy will review the plans for joint submarine cable production and supply chain development. 

“Vietnam is growing fast as a renewable energy hub in Southeast Asia and submarine cables are a key infrastructure element for the expansion of the renewable energy supply chain. Together with LS Marine Solution, we will lead the Southeast Asian market based on our technological prowess and supply chain competencies,” said LS Eco Energy CEO Sang-ho Lee. 

PTSC is currently implementing a large-scale project to supply eco-friendly electric power generated at an offshore wind power complex to Singapore through submarine cables, and LS Eco Energy is looking for a way to cooperate in the project.
