What MidOcean Wind LLC does

MidOcean Wind LLC is a Wilton, Connecticut-based marine solutions provider that serves U.S. offshore wind farm developers. Founded in 2015 (per company history; the firmographics record lists 2017) as a subsidiary of MidOcean Marine—a niche shipping investment company focused on environmentally conscious, secular-growth sectors—MidOcean Wind operates U.S.-flagged vessels and marine logistics for the construction, commissioning, and O&M phases of offshore wind installations. The company's primary differentiator is its Jones Act compliant ship-owning position, supported by 35+ years of U.S. vessel operating experience drawn from its parent and a fleet of 20+ ships historically.

The company's product portfolio is anchored in support vessels—specifically Crew Transfer Vessels (CTVs) and Service Operations Vessels (SOVs)—and extends into terminal and logistics services, 24/7 marine coordination, and nautical and technical engineering. Through its joint venture WINDEA Offshore USA, MidOcean combines its own U.S. assets with three German maritime specialists: Bernhard Schulte Offshore (SOV operations and shipowning), Buss Offshore Solutions (installation, marshaling, and O&M terminals), and Ems Maritime Offshore (marine coordination via the VENTUSmarine control room). Buss Wind Services provides engineering support. Five vessels (four newbuild CTVs and one converted PSV) are currently operating in New England, with a sixth CTV scheduled for 2025, and storage and logistics facilities are maintained at multiple port locations.

The business model is enterprise services revenue, with contracts quoted and tailored to individual offshore wind projects. Pricing is not publicly disclosed. The go-to-market is direct enterprise engagement with U.S. offshore wind farm developers, supplemented by the partner network that delivers the bundled, single-point-of-contact marine offering intended to reduce interface risk for developers. The company captures revenue through vessel charter/operations, terminal services, and engineering service agreements, with no disclosed funding rounds, revenue figures, or external investors.

Expansion highlights4 records

Direct peers

• North Star Renewables: U.K.-based SOV operator with growing U.S. ambitions, including service operations vessels for U.S. offshore wind. Directly comparable to MidOcean's SOV business line and target developer customers.
• ESVAGT: Danish-headquartered SOV specialist and the dominant European SOV operator, partnered with a U.S. yard to build Jones Act SOVs. Highly comparable to MidOcean's SOV-focused offering, though currently Europe-centric.
• Edda Wind: Norwegian pure-play offshore wind SOV/CTV owner with a growing fleet. Comparable because it competes in the same offshore wind service vessel category as MidOcean, although primarily in European waters.
• Windcat Workboats: European CTV specialist and one of the largest CTV operators in offshore wind. Comparable to MidOcean's CTV operations in New England, though it lacks MidOcean's Jones Act U.S.-flagged position.
• Seacat Services: U.K.-based CTV operator dedicated to offshore wind crew transfer, recently acquired by BOURBON. Closely comparable to MidOcean's CTV operations in terms of customer type and service.
• Crowley Maritime: U.S.-based, Jones Act compliant operator expanding into offshore wind vessel services (notably the eWolf CTV with ESB). Directly comparable because it competes for the same U.S.-flagged CTV/SOV charters from MidOcean's developer customer base.
• Edison Chouest Offshore: Large U.S.-flagged offshore vessel operator with CTVs and SOVs serving U.S. offshore wind. Comparable to MidOcean as a Jones Act compliant provider of crew transfer and service operations vessels for the same U.S. developer clients.

Broad incumbents

• Vroon Offshore: Dutch offshore vessel owner-operator (W2W vessels, SOVs) serving European offshore wind and oil and gas. Comparable to MidOcean as an offshore wind service vessel provider, though not U.S.-domiciled.
• BOURBON: Global offshore vessel operator with CTV/PSV exposure transitioning toward offshore wind. Comparable to MidOcean in vessel operations and offshore wind, but operates as a broad incumbent across oil and gas and renewables.

Regional players

• Bisso Marine: U.S.-based offshore service and construction company with Jones Act compliant vessels supporting Gulf of Mexico and emerging U.S. offshore wind work. Comparable in U.S. marine service capability, though primarily a Gulf/U.S. South operator rather than Northeast-focused.
