Six offshore wind companies present U.S. supply chain capabilities to Congress at Oceantic’s inaugural Federal Summer Showcase

Six American offshore wind companies took their industry directly to Capitol Hill this month, transforming a congressional office building into a hands-on demonstration of U.S. supply chain capabilities.

During Oceantic Network’s inaugural Federal Summer Showcase & Energy Action Day at the Rayburn House Office Building in Washington, D.C., members DeTect, Indeximate, LS Cable & System / LS GreenLink, Riggs Distler, the United Brotherhood of Carpenters / NASRCC, and WindServe Marine engaged Congressional staff and nine congressional offices—including Representative Seth Magaziner (D-RI)—with the technologies, vessels, and workforce behind offshore wind development across the country.

Six members bring offshore wind industry to Capitol Hill

The Rayburn House Office Building isn’t usually known for live industrial demos. That changed during Oceantic Network’s inaugural Federal Summer Showcase & Energy Action Day, when six member companies turned the congressional venue into something closer to a working exhibition floor.

Oceantic’s decision to go interactive reflects a broader push to make offshore wind’s economic and industrial contributions visible to policymakers.

Congressional staff moved through displays of subsea cable technology, vessel models, and monitoring equipment—getting a firsthand look at the domestic supply chain behind offshore wind. After the showcase, participating companies kept those conversations going, sitting down with nine Congressional offices and meeting directly with Representative Seth Magaziner (D-RI). On the table: American manufacturing, domestic shipbuilding, workforce development, energy security, and private investment.

Why the industry brought its supply chain to Congress

Offshore wind operates in a policy environment that demands constant engagement with federal decision-makers. Regulatory questions, permitting frameworks, and energy security debates all play out in Washington, and the industry’s ability to shape those conversations depends partly on whether legislators understand what the sector actually does.

That’s the gap the Federal Summer Showcase was designed to close. Rather than relying on briefing documents or lobbying visits alone, Oceantic organized an interactive, hands-on format where Congressional staff could see and engage with real technologies. The goal was to make the supply chain tangible—to show that offshore wind isn’t an abstract policy concept, but a network of American companies, workers, and infrastructure already operating across the country.

Participating companies framed their work around themes that resonate across the political spectrum: domestic job creation, private-sector investment, national energy security. It’s a deliberate strategy, and the showcase gave them a direct channel to deliver it.

What the showcase displayed: technologies, vessels, and workforce

The six participating companies covered a wide range of the offshore wind supply chain—from deep beneath the ocean floor to the vessels that service turbines above it.

DeTect demonstrated its advanced radar and remote-sensing systems. The company’s technology addresses one of offshore wind’s persistent technical challenges: the interaction between large turbine structures and aviation and defense radar. Its tools support the coexistence of offshore energy development with critical national security operations.

Indeximate presented subsea cable telemetry, electrical diagnostics, and acoustic monitoring technologies. These systems give operators real-time data on cable conditions, flagging risks tied to thermal stress, seabed movement, and physical interference—capabilities that directly support the resilience of subsea infrastructure.

LS Cable & System / LS GreenLink showcased high-voltage subsea and underground power cables, the critical link between offshore wind projects and the onshore grid. Through its LS GreenLink subsidiary, the company is actively expanding its U.S. manufacturing footprint and contributing to a domestic supply chain for subsea transmission.

Riggs Distler, a union utility construction and heavy industrial contractor founded in 1909, highlighted its heavy civil, mechanical, electrical, fabrication, and marine construction capabilities. That work spans the assembly and delivery of major offshore wind project components along the Eastern United States.

UBC/NASRCC represented the workforce side of the equation. The United Brotherhood of Carpenters and the North Atlantic States Regional Council of Carpenters train carpenters, millwrights, pile drivers, and other skilled tradespeople through apprenticeship programs built specifically for offshore wind’s demands.

WindServe Marine displayed Jones Act-compliant vessels built in U.S. shipyards and crewed by American mariners. The company’s vessels transport technicians and personnel to offshore project sites—a direct example of how offshore wind investment flows into domestic shipbuilding and maritime employment.

Background: Oceantic Network and the U.S. offshore wind supply chain

Oceantic Network is an industry association representing companies across the U.S. offshore wind supply chain. Its membership spans subsea infrastructure, marine vessels, advanced monitoring technology, construction, and skilled labor—reflecting just how many industries intersect with offshore wind development.

One of the sector’s defining regulatory features is the Jones Act, which requires that vessels operating in U.S. waters be built domestically and crewed by American workers. That requirement creates a direct link between offshore wind investment and jobs in U.S. shipyards and the maritime workforce. WindServe Marine’s participation at the showcase made that connection concrete.

The Federal Summer Showcase marks Oceantic’s first structured effort to bring member companies’ capabilities directly before federal legislators in an interactive format—a notable shift from traditional industry advocacy, moving beyond written testimony and briefings toward physical demonstration.

A broader push to make offshore wind’s contributions visible

The inaugural Federal Summer Showcase put six distinct segments of the U.S. offshore wind supply chain in front of Congressional staff and offices simultaneously. Radar systems, subsea cable diagnostics, Jones Act vessels, apprenticeship-trained tradespeople—together, the participating companies illustrated the domestic breadth of the sector in a way that a standard briefing rarely achieves.

LS Cable & System / LS GreenLink showcased high-voltage subsea and underground power cables, the critical link between offshore wind projects and the onshore grid. Through its LS GreenLink subsidiary, the company is actively expanding its U.S. manufacturing footprint and contributing to a domestic supply chain for subsea transmission.

The meetings with nine Congressional offices and Representative Magaziner extended those conversations well beyond the exhibition floor and into direct legislative engagement.
