Reflections from OTC 2026: Advancing the Future of Offshore Resources

By Mark Mussett

The Offshore Technology Conference (OTC) once again brought together the global offshore energy and maritime community in Houston, Texas, from May 4–7, 2026. Founded in 1969, OTC has grown into one of the industry’s most significant convenings—ranking among the top 100 trade shows in the United States and one of the 50 largest meetings nationwide. Today, its global portfolio of events has welcomed more than three million professionals and continues to serve as a leading platform for technical exchange, collaboration, and innovation across the offshore sector.

 As a member of the Society for Mining, Metallurgy and Exploration (SME) Technical Subcommittee, I attended this year’s event not only to support our committee’s work, but also to engage in broader discussions shaping the future of offshore resource development.

I was encouraged by how this year’s proceedings considered marine minerals as a component of the industry-wide dialogue surrounding offshore resources, supply chains, subsea technology, and long-term resource security.

A Global Forum at a Turning Point

OTC remains one of the premier gatherings for offshore energy professionals, with an estimated 25,000 attendees this year. The conference serves as a unique platform for collaboration across offshore oil and gas, marine minerals, subsea engineering, and emerging ocean industries.

The Houston event combines four days of technical sessions with an expansive exhibition floor and is guided by a consortium of 13 professional societies. As part of SME’s contribution to the Technical Committee, our subcommittee works to ensure marine minerals remain a visible and credible component of the broader offshore industry. We addressed this goal in 2026 by convening a session of technical presentations examining engineering, economics, and exploration advancements focused on seafloor mineral resource delineation and development. Additionally, we were delighted to welcome the International Marine Minerals Society (IMMS) as an invited external society, and to attend its session of panel discussions examining extraction technology, regulations, and environmental impacts from current technology. The Technical Committee’s acceptance of IMMS involvement in this year’s conference reinforces the growing relevance of marine minerals within the offshore industry ecosystem.

IMMS Panel: Growing Global Interest in Marine Minerals

The IMMS-led session, Engineering the Future of Deep-Seabed Mining: Collection, Transport, and Processing, drew approximately 200 participants and reflected growing interest in the sector across technical, regulatory, and commercial audiences.

The session brought together industry leaders, scientists, policymakers, technology developers, and government representatives to discuss critical issues shaping the future of marine mineral development. Moderated by Michelle Foss, Dr. Mark Luther, and Dr. Samantha Smith, the discussion included perspectives from organizations spanning research institutions, government agencies, and commercial operators.

Topics included:

• Offshore mining infrastructure and system development

• Regulatory pathways and international policy alignment

• Environmental monitoring and management approaches

• Collection, transport, and processing technologies

Panelists represented a wide range of perspectives—from NOAA and BOEM to private-sector innovators—creating a balanced and constructive discussion about the opportunities and challenges facing the industry.

The strong turnout also underscored the growing overlap between traditional offshore communities and those focused on marine minerals and subsea resource development. That convergence is becoming increasingly visible across industry forums worldwide.

SME Panel: Technical Insights with Strategic Implications

The SME-sponsored Marine Mining session provided a strong technical complement to the broader policy discussions taking place throughout OTC. Presentations highlighted emerging technologies, operational concepts, and economic considerations that could meaningfully influence how offshore resources are developed in the years ahead.

As the sector matures, demonstrating operational practicality, economic competitiveness, and credible environmental management will be essential to moving projects beyond the conceptual stage. Discussions throughout OTC reflected a growing recognition that technical innovation alone is not enough; long-term success will depend on integrating engineering, environmental science, policy, and stakeholder engagement into a cohesive development framework.

From OTC to UMC: Continuing the Conversation

While OTC provides a broad, cross-sector platform, industry attention now turns to the next major gathering of the year: the Underwater Minerals Conference (UMC 2026).

Now in its 54th year, UMC is widely recognized as the largest international conference dedicated specifically to marine minerals. Organized by the International Marine Minerals Society (IMMS) in partnership with a Japanese host committee—including JOGMEC, JAMSTEC, DORD, E&E Solutions, and Osaka Metropolitan University—the conference brings together participants from more than 25 countries across government, academia, and industry.

Chaired by Dr. Mark Luther, President of IMMS, the 2026 program will continue a longstanding tradition of advancing discussion around exploration, environmental science, technology development, regulatory frameworks, and commercial strategy.

For those involved in offshore mineral development, UMC provides a more specialized forum to build on many of the themes introduced at OTC and continue the collaborative discussions needed to advance the sector responsibly.

Final Thoughts

OTC is one of several important touchpoints in a broader cycle of industry engagement taking place across the offshore minerals sector. Earlier this year, discussions at events such as the ACCF Offshore Critical Minerals Forum, SME MINEXCHANGE, the Society for Underwater Technology (SUT), and Oceanology International reflected growing interest in offshore resources from policymakers, engineers, scientists, investors, and technology developers alike.

Together, these forums highlight a broader industry trend: marine minerals are steadily moving from a niche discussion toward more mainstream consideration across multiple disciplines. Policy, science, engineering, environmental management, and capital markets are increasingly intersecting as stakeholders work to better understand both the opportunities and challenges associated with offshore resource development.

Odyssey is excited to be an active part of this evolution—contributing research, technical insight, and practical experience to help advance knowledge and support the responsible development of this emerging sector. Each forum plays a distinct role in advancing that conversation, and the continued collaboration across sectors will be important as the industry continues to evolve.
