Maritime Blue is a strategic alliance focused on maritime innovation and sustainability. Founded in Seattle and working globally, Maritime Blue connects industry, government, academia, entrepreneurs and communities to accelerate solutions that support a thriving ocean, healthy communities and resilient economies.

Its areas of focus include maritime decarbonization, sustainable fishing and seafood, renewable ocean energy, digital transformation and blue innovation ecosystems.

OOWS is designed as a cross-sector and international gathering. Participants include industry leaders, policymakers and government leaders, Tribal governments and communities, investors and funds, researchers and academics, startups and innovators, foundations and NGOs, port authorities, maritime clusters and international delegations.

Maritime Blue’s role is to convene and connect these groups so that ideas, expertise, funding and real-world needs can come together. The goal is not simply to put different sectors in the same room, but to create relationships and initiatives that continue beyond the event itself.

In 2025, OOWS included more than 50 events, drew more than 1,200 registrants and represented 15 countries, providing a strong foundation for the event’s second U.S. edition in 2026.

Seattle and the Pacific Northwest have a deep connection to the ocean and maritime economy, bringing together a working waterfront, maritime companies, technology innovators, research institutions, policymakers and communities with longstanding ties to the water.

OOWS is intended to showcase that ecosystem while also connecting Seattle with ocean clusters, delegations and leaders from around the world.

The 2026 event represents a shift from dialogue toward action. This year, OOWS will focus more directly on the difficult decisions, unresolved questions and cross-sector collaboration needed to turn ocean innovation into meaningful progress. The 2026 event is designed around action, with programming tied to technology deployment, lasting cross-sector partnerships, policy engagement, market development and investment.

No. While OOWS brings together leaders working directly in the maritime and Blue Economy, its purpose is deliberately cross-sectoral. The week includes summits alongside cultural events, community activities, youth and workforce development programming and other partner-led events.

The week is relevant to entrepreneurs, investors, policymakers, researchers, community leaders, students and others interested in ocean health, climate and sustainability, technology, economic development and the future of waterfront communities.

Any interested parties should consult the Luma calendar to learn more about individual events.

OOWS events take place across the Seattle area. Because individual events have different locations and access requirements, attendees should check the One Ocean Week Seattle 2026 Luma calendar for the latest details and registration information.

Partner-led events are a central part of the week, giving organizations from across the maritime, research, education, government and community ecosystem an opportunity to contribute programming tied to their areas of expertise

Costs vary per event, and some events are free. Please see the One Ocean Week Seattle 2026 Luma calendar for cost details for each event.

Registration is handled per event. Since events are hosted by different organizations across the week, you’ll need to register individually for each one you plan to attend through the One Ocean Week Seattle 2026 Luma calendar. We recommend registering for each ahead of time, as some may have limited capacity.

OOWS is designed as an in-person event, and programming is not livestreamed or otherwise available virtually. We encourage those unable to attend in person to follow Maritime Blue’s LinkedIn for updates and highlights from the week, as well as recaps shared after the event.

OOWS conversations are also expected to touch on broader issues shaping the maritime and ocean economy, including maritime decarbonization, clean fuels and green shipping corridors, ocean science and monitoring, sustainable seafood, renewable ocean energy, digital innovation and the policies and investment needed to bring new technologies to market.

The broader OOWS platform has historically focused on areas including vessel electrification, ocean monitoring, aquaculture, sustainable fisheries and connecting innovators with capital and commercialization partners.

No. OOWS events take place across the greater Seattle area, and hosts can choose a venue and neighborhood that best fits their event.

Existing events are welcome. If you already have an event planned for that week, you’re welcome to add it to the OOWS calendar as long as it aligns with the week’s focus on ocean action, innovation and collaboration. Events with external registration pages should select the ‘Add and external event’ option on Luma.

OOWS 2026 is intended to give reporters access not only to individual innovations or projects, but to the larger decisions shaping the Blue Economy.

The week brings together voices from government, finance, science, industry and the international community to examine where progress is happening, where it is stalled and what needs to happen next. OOWS 2026 is a forum for substantive, face-to-face discussion of the Blue Economy’s most difficult challenges.
