Eleven years servicing the boats that matter — and the controls that run them.

A lifetime maintaining and operating the equipment

The depth of OCSMARINE's offer isn't just eleven years on Rapp Marine control systems — it's a lifetime maintaining and operating the equipment itself. The founder started commercial fishing in Alaska at age ten, kept commercial fishing through age twenty-eight, and spent every winter through that era as a shipyard apprentice and self-employed shipwright rebuilding the same boats he ran in summer. The pivot to full-time repair and service work happened in 2013. He has been the watch officer when a winch failed at 3 a.m., the operator running the hydraulics on his own vessel, and the shipwright when a hull needed plating — long before he ever wired a CANbus PLC cabinet. That layered operator-then-service career is the reason OCSMARINE's troubleshooting calls don't sound like vendor-script reads, and why time-to-repair on a vessel underway is measured in hours, not days.

The NOAA Fisheries Survey Vessel fleet

All five NOAA Office of Marine and Aviation Operations (OMAO) Fisheries Survey Vessels were serviced directly by David Johnson during his tenure at Rapp Marine USA. The vessels and their primary missions:

• Oscar Dyson Alaska pollock and ecosystem surveys; homeport Kodiak, AK · Pentagon Fishery & Pentagon Research upgrade — service and installation lead while at Rapp Marine USA
• Bell M. Shimada West Coast fisheries and ecosystem research; homeport Newport, OR
• Reuben Lasker West Coast pelagic and ecosystem surveys; homeport San Diego, CA
• Henry B. Bigelow Northeast U.S. fisheries surveys; homeport Newport, RI
• Pisces Gulf of Mexico and Caribbean surveys; homeport Pascagoula, MS

Why OCSMARINE exists

Rapp Marine deck equipment and Rapp Marine control systems aboard the NOAA Fisheries Survey Vessel fleet, subsea construction vessels, dive-support fleets, the U.S. tug fleet, and U.S. commercial fishing platforms remain in active daily service. That installed base requires continued, responsive service support — and a path forward from the legacy systems to modern CANbus upgrade installations.

OCSMARINE LLC was formed to provide that support and those upgrade installations under a Washington-incorporated company that contracts directly with U.S. federal agencies, prime contractors, and commercial operators — and deploys field service worldwide. The founder is the same person who built the depth of knowledge on these systems — eleven years of dedicated FSV-fleet service, plus service and installation lead on the most recent Pentagon Fishery / Pentagon Research upgrade (delivered while at Rapp Marine USA).

Background

• Senior Marine Service Engineer, Rapp Marine USA, Seattle — May 2015 through May 2026 (eleven years)
• Service and installation lead on custom Pentagon Fishery and Pentagon Research control stations, CANbus PLC cabinets, and CBUS-F / CBUS-R communications wiring (project delivered for NOAA Oscar Dyson)
• Rebuilding, testing, troubleshooting, and installation of hydraulic deck equipment: trawl winches, net reels, gilson winches, cranes, anchor-handling systems
• Dedicated coverage of all five NOAA Fisheries Survey Vessels
• Direct working relationships with NOAA OMAO port engineers, masters, and chief engineers
• Commissioning, troubleshooting, and recovery work on Pentagon PTS control systems beyond what vendor documentation covers
• Remote-access installation on Pentagon CBus systems — years of experience reducing vessel downtime by supporting customers without flying out

Global field experience

Pentagon and Rapp Marine installations are global. So is the founder's service history:

• Norway and Amsterdam — sea-trial service work on new Rapp Marine installations
• Singapore — offshore service on a subsea construction vessel
• Gulf of Mexico — ROV-class vessels and deep-sea dive-support vessels
• South America via Panama Canal — Rapp Marine anchor-handling and crane service on expedition cruise vessels
• U.S. Pacific, Atlantic, and Gulf coasts — NOAA FSV service across all five homeports
• Pacific Coast tug fleet — Bay-Delta Maritime and Sause Bros. Rapp / Pentagon-controlled tow winch installations

Project leadership

OCSMARINE LLC is a senior service engineering resource, not just a field-service provider. The founder has been hired as service lead by NOAA port engineers to fly in, supervise crews of three to four technicians plus subcontractors, and execute multi-week shipyard refits and sea-trial qualification work.

Before Rapp Marine

The work history before joining Rapp Marine in 2015 is the reason the engineering knowledge holds up at sea, on deck, and in the shipyard:

• Commercial fishing (1997 – 2012) — Deck Boss on F/V Windward (longline halibut, Kodiak, AK); Engineer/Operator on F/V Major for Sargent Major Inc. (hydraulics, refrigerated seawater, main engine, generators, Transvac, vessel piloting around Kodiak Island)
• Self-employed marine shipwright — Rebuilds, fab, and welding on F/V Denise Marie, F/V Hotspur (Port Townsend Shipyard), and F/V Windward (Delta Marine Shipyard): twin-screw repower with John Deere 6068 tier-2 diesels, aluminum top house and flush deck fab, steering and hydraulic system rebuilds, ultrasonic hull testing
• Apprentice Shipwright, Ocean Bay Marine Inc. (Seattle) — Wooden boat restoration, remodel, and repair on commercial, pleasure, and historical vessels up to 150 ft
• Heavy-duty mechanical & electrical service technician — multi-year service-tech background outside the marine sector covering drivetrain, air systems, electrical, and 24-hour field response. Foundational mechanical and electrical depth that supports OCSMARINE's current marine service work.
