Some of the partners & clients we’ve worked with


At Midco Diving & Marine Services, we take on the toughest underwater conditions you can imagine. After nearly twenty years of commercial diving experience from underwater construction to municipal water tank repair – we’ve gone in where few others would even think. Highly contaminated water, confined work spaces, radiation, zero visibility, and high-altitude operations are all fair game. Whatever you’ve got in mind, we welcome the challenge.
