LR's Submarine Assurance Framework is a plan to help navies and designers from the start to the end of making submarines.

The AiP has been issued for Hanwha Ocean’s independently developed 2,000 tonne export submarine platform, using LR’s Submarine Assurance Framework. It confirms that the concept design meets internationally recognised standards and provides early-stage assurance on safety, interoperability and design robustness. 

LR’s Submarine Assurance Framework is designed to support navies and designers from concept through all stages of the submarine’s operational cycle, including life extension, by combining naval standards, classification expertise and a structured approach to risk.  

A global team of naval and submarine specialists

For this project, LR assembled a global team of naval and submarine specialists to support the review, culminating in a technical workshop at Hanwha Ocean’s headquarters in Seoul. The approval reflects how LR’s independent naval assurance supports shipbuilders in accessing the export market. 

Reinforces LR as a trusted adviser for complex naval programmes.

David Lloyd, Vice-President Naval and Government Business at Lloyd’s Register, said: “This AiP issued under our Submarine Assurance Framework demonstrates how independent, outcome-based assurance can help reduce technical risk and build confidence with customer navies. 

“The approval underlines the growing role LR has in assurance in the defence sector and reinforces our position as a trusted adviser for complex naval programmes.”

Hanwha Ocean’s world‑class submarine design capabilities. 

Il-Hong Kim, Senior Vice President from Hanwha Ocean’s Naval Design Department, said: “Achieving AiP for our 2,000‑ton submarine is a powerful confirmation of Hanwha Ocean’s world‑class submarine design capabilities. 

“Working closely with Lloyd’s Register, we will continue delivering tailored solutions that meet diverse national requirements and strengthen the global presence of Korea’s naval defence industry.”
