What OCSMARINE handles.

Marine service engineering across deck machinery, hydraulics, electrical, and Rapp Marine control systems — service, repair, troubleshooting, parts replacement, custom panel design and build, PLC/HMI integration, and CANbus upgrade installation work. Commercial fishing, tug, subsea construction, expedition, and federal research vessels. Seattle headquartered, worldwide field deployment. Engagement structure scoped by conversation.

OCSMARINE LLC's deepest specialty is the Rapp Marine Pentagon control system installed base — service, repair, troubleshooting, and parts replacement across the full Pentagon family: Pentagon PTS, Pentagon Fishery, Pentagon Research, Pentagon ROV, Pentagon Tug, and Pentagon XT. Around that specialty sit the foundations: marine deck machinery rebuild and repair, hydraulic systems service, electrical and motor control, custom panel design and build, PLC/HMI integration, VFD and field-bus work, sea-trial commissioning, remote access, and parts sourcing.

CANbus PLC cabinet design & build

Behind every modern Pentagon-class control station is a custom PLC cabinet — multi-I/O modules, contactors, motor drives, terminal blocks, fire suppression — that translates operator commands into deck-equipment motion and reports sensor status back over CANbus.

  • Custom PLC cabinet design and fabrication
  • PLC multi-I/O module integration and configuration
  • Pump, traction winch, storage drum, and CBUS-R / CBUS-F node wiring
  • CO2 fire suppression integration; documentation for vessel classification

CANbus upgrade installations

Installation and commissioning of custom CANbus upgrade packages on existing Pentagon-equipped vessels — modernizing the legacy installed base vessel by vessel. OCSMARINE installs the upgrade; the project is bounded by what the vessel needs.

  • Site survey and vessel-specific upgrade planning
  • Removal of legacy hardware; install of custom panels, PLC cabinet, and CANbus wiring
  • Integration with vessel power, propulsion, and existing deck equipment
  • Sea-trial commissioning, acceptance testing, and crew handoff

The full Pentagon family

Rapp Marine's Pentagon control system family covers six distinct vessel-class variants, built on different generations of HMI and PLC technology. OCSMARINE has hands-on depth across all of them and a clear migration path from legacy Pentagon PTS to modern Pentagon CBus.

  • Pentagon PTS — the original Programmable Trawl System; troubleshooting, retrofit, recovery, and migration support on the legacy installed base
  • Pentagon Fishery — commercial fishing variant; CBus-F internal bus; trawl winch, net drum, and gilson winch control
  • Pentagon Research — federal and academic research variant; CBus-R internal bus; science deck operations, NOAA FSV fleet installations
  • Pentagon ROV — subsea construction variant; active heave-compensated launch-and-recovery systems for ROV and heavy-lift
  • Pentagon Tug — CBus-T internal bus; tow winch and anchor-handling control across the U.S. tug fleet
  • Pentagon XT — modern extended tug platform on CODESYS PLC + web-based HMI; tow winch wheelhouse control and supporting hydraulics
  • HMI tuning, operator training, and CBus / CANbus upgrade installation planning across all six variants

Rapp Marine deck equipment & hydraulics

The deck-side of the same Rapp Marine installations OCSMARINE controls electrically: trawl winches, net drums, gilson winches, heavy-lift winches, anchor handling, launch-and-recovery systems (LARS) for dive bells and ROVs, and the high-pressure hydraulics that drive all of it.

  • Trawl winch and net drum service — bearing changes, brake overhaul, hydraulic diagnosis
  • Heavy-lift winch service and rebuild work
  • Gilson winch and auxiliary deck machinery troubleshooting
  • Launch-and-recovery system (LARS) service for science platforms, dive bells, and ROVs
  • Hydraulic pump, valve, and accumulator service on Rapp-installed power packs
  • Dry-dock attendance, sea-trial engineering, acceptance testing

Engineering leadership & project management

OCSMARINE LLC operates as a senior service engineering resource as well as a field-service provider. The founder has led multi-vessel international deployments, supervised technicians on dry-dock and refit work, and trained customer crews on Pentagon-controlled systems. When PE-stamped design or naval architecture deliverables are part of a scope, OCSMARINE teams with credentialed subcontract partners.

  • Hired as service lead by NOAA port engineers to fly in, supervise crews of 3–4 technicians plus subcontractors, and execute shipyard refits
  • Sea-trial service lead on new Rapp Marine installations — yard work in Norway and Amsterdam
  • Multi-vessel deployment management — international travel across subsea construction, dive support, U.S. tug, and expedition fleets
  • Crew training, port-engineer handoff, and engineering documentation
  • Subcontracted service-engineering project leadership for primes, integrators, and federal contracting offices
  • Teaming with PE-credentialed engineers and naval architects when a contract scope requires stamped design deliverables

Remote service & remote access

Remote-access installation on Pentagon CBus systems became a core OCSMARINE service line for one reason — customers on vessels worldwide could not always get a control-systems engineer on site quickly. The result is dramatically reduced vessel downtime and travel cost, plus practical remote-support contracts for federal and commercial operators.

  • Remote-access installation on Pentagon PTS, Pentagon Fishery / Pentagon Research, and related control systems
  • Remote diagnostics, software updates, and parameter tuning while the vessel is at sea or in port worldwide
  • Secure remote support arrangements suitable for federal and commercial operators
  • Backup of control-system configurations and recovery-ready archives

Parts sourcing & supply

OCSMARINE has working material-sourcing channels for Rapp Marine spare parts, Pentagon control-system components, CANbus hardware, and broader marine hydraulics — drives, motors, sensors. Domestic OEM support for the legacy installed base has thinned. Knowing where to find the right component can be the difference between a one-day fix and a one-month outage.

  • Rapp / Pentagon / CANbus spare-parts sourcing and obsolescence planning
  • Equivalent-part identification when OEM parts are no longer available
  • Broader marine hydraulic motor, drive, sensor, and board sourcing

Fleet segments we serve

The Rapp / Pentagon / CANbus system family is installed across five distinct fleet segments. The founder has hands-on service history across all of them — and across the named vessels below, the installations are publicly documented in OEM press releases and trade media.

Fisheries research — NOAA Fisheries Survey Vessel fleet

The NOAA Office of Marine and Aviation Operations (OMAO) FSV fleet was the focus of eleven years of dedicated service: Bell M. Shimada, Oscar Dyson, Reuben Lasker, Henry B. Bigelow, and Pisces. All five operate Rapp Marine deck equipment with Pentagon control. Oscar Dyson is the most recent Pentagon Fishery & Pentagon Research upgrade.

Subsea construction & dive support — Pentagon CBus heavy-lift / ROV LARS

Rapp Marine's Pentagon CBus active-heave-compensated heavy-lift and ROV launch-and-recovery system is installed across subsea construction fleets — including vessels documented in Rapp Hydema and TechnipFMC press releases such as Deep Orient and Deep Arctic — and on Rapp electric / AHC dive-support and IMR winch retrofits including the Kelly Ann Candies and Wyatt Candies.

Tug & towing — Pentagon-controlled tow winch packages

Rapp electric and hydraulic tow winches with Pentagon wheelhouse control are installed across the U.S. tug fleet, including Baydelta Maritime's Delta Teresa (Rapp HA-75E / AHTW-50E), Sause Bros. Ocean Towing's Apache and Geronimo (Rapp TOW-22031 main tow, PW-4002-B pendant, TOW-4002-BB hawser), and Western Towboat's custom Rapp Hydema winch installation — all documented in Pacific Maritime and Professional Mariner coverage.

Expedition & passenger fleet

Rapp Marine–built top-deck cranes, anchor-handling systems, and electric capstans and winches are installed on U.S.-flagged expedition vessels operating South America and Panama Canal routes — including Lindblad Expeditions' National Geographic Quest and National Geographic Venture (built by Nichols Brothers Boat Builders, Freeland, Washington). Field service and remote support apply across the same Rapp equipment family.

Commercial fishing — Pacific and Bering Sea fleet

Rapp Marine has historically supplied a substantial share of trawl winches, net drums, gilson winches, and supporting hydraulics on the high-end U.S. commercial fishing fleet. The same field service applies — bearing changes, brake overhaul, hydraulic diagnosis, Pentagon HMI work.
