DOER Marine
Builds and operates deep-ocean ROVs and other underwater systems for exploration, research, and commercial work.[3]
DOER Marine, originally Deep Ocean Exploration and Research, works as a marine consulting and engineering company that designs, manufactures, and supports underwater systems for ocean work. Its core business covers building underwater vehicles and related equipment, including science-class remotely operated vehicles, autonomous underwater vehicles, and classed human-occupied submersibles. Those vehicles serve as multi-mission platforms for deep-sea exploration, multidisciplinary oceanographic research, underwater archaeology, mapping, infrastructure inspection, search and recovery, cinematography, survey work, and subsea observatory support. The company practices circular manufacturing, selecting materials for strength, functionality, recyclability, or reuse at end of life. Beyond vehicle construction, DOER offers operations support, training, launch and recovery systems, equipment integration, recertification, and retrofits for existing systems. It provides marine consulting and research services on topics such as coastal resilience, vessel feasibility studies, pipeline and tunnel intervention, adaptive reuse, containerized solutions, sampling and collection tools, monitoring and enforcement in marine protected areas, and expert witness work. The company offers field operations and support management consulting, testing, and custom machining for the marine research and exploration sector. Its work serves research institutions, government and industry users, and clients needing specialized underwater capabilities, including expedition support and bespoke vehicle design. DOER runs a dive shop and maintains partnerships, reflecting a broader presence in ocean-related operations and education, while its products and services center on enabling underwater access, research, and mission execution in demanding marine environments.
