As of my last knowledge update in September 2021, there's no widely known information about a "Dolphin" submarine in the Andaman Islands. It's possible that this could be a recent development or a local initiative that has emerged after my last update.
If there has been a new submarine experience or attraction introduced in the Andaman Islands called the "Dolphin" submarine, I recommend checking with local tourism authorities, travel websites, or news sources for the most up-to-date and accurate information. They can provide details about the experience, its features, and how to participate.
Please keep in mind that my information might not be current, so I recommend verifying this with reliable sources to get accurate and timely information about any new developments in the Andaman Islands.
