Marine Condition Monitoring

Edge-to-cloud shaft power, vibration, and temperature monitoring for workboats and commercial vessels — from a single torque measurement to whole-drivetrain condition monitoring.

ITM brings its field-proven edge platform, ITM Connect, to the propulsion drivetrain. Starting with a wireless shaft torque and power measurement — built on the Binsfeld TorqueTrak collar — the same on-board system folds in vibration and temperature monitoring across the engine, gearbox, line shaft, and stern tube. The result is turnkey, low-touch machinery-health monitoring designed for fleets that can’t keep an engineer aboard.

How ITM serves Marine

Shaft Torque & Power

Shaft Torque & Power

A Binsfeld TorqueTrak collar clamps onto the propeller shaft and streams torque and power to the on-board compute — no engineer aboard.

Drivetrain Vibration

Drivetrain Vibration

Wireless vibration nodes watch the main engine, gearbox, and line shaft — order-tracked and standards-informed for early fault detection.

Bearing Temperature

Bearing Temperature

Wireless thermocouple and infrared nodes track stern-tube and line-shaft bearing temperatures, flagging rate-of-rise before a bearing lets go.

Packaged Marine Monitoring

Packaged Marine Monitoring

ITM Connect acquires, on-site analytics compute, and dashboards present the whole drivetrain — ship and shore — as one packaged system.

From the shaft to the whole drivetrain

1. Instrument the shaft

The Binsfeld collar’s TX50 transmitter sends shaft torque over Bluetooth Low Energy directly to the on-board compute. A two-tier acquisition captures 1 Hz KPI trends continuously and fires scheduled high-rate burst FFTs, so misfire, propeller damage, and gear-mesh signatures surface without anyone watching a screen.

2. Extend to the whole boat

Add wireless thermocouple, infrared, vibration, and hull-strain Edge Nodes, plus onboard fuel-flow and GPS feeds. The nodes are duty-cycled — waking on a roughly 60-second schedule or instantly on high vibration — and their readings are time-correlated with the live shaft data. The payoff case is the stern-tube bearing save: catching a bearing’s rate-of-rise before it becomes a casualty.

3. Diagnose the drivetrain

For a full picture, up to six wireless triaxial vibration nodes run from the engine to the stern support. Order-tracked and standards-informed — drawing on ISO 10816-6, 20283-4, and 20816-9 — the system supports port-versus-starboard comparative diagnostics on twin-screw boats. Final alarm limits are always set per vessel, OEM, and class society.

Why marine operators monitor

Regulation has turned propulsion power into a measured, reportable quantity — and the economics of an avoided failure are stark.

  • Carbon rules (IMO EEXI/CII) — measured shaft power is the reference for a vessel’s carbon-intensity rating, which means continuous, auditable torque and power data.
  • Towing-vessel safety (USCG Subchapter M) — the machinery-health records this monitoring generates fit directly into a towing safety management system’s maintenance evidence.
  • Class notations (DNV TMON, Shaft align) — class programs reward the multi-parameter shaft monitoring ITM provides, and can extend tailshaft survey intervals.
  • Loss economics — stern-tube bearing failures are among the most expensive marine machinery claims, and documented condition-based-maintenance programs report sharply fewer unplanned failures and longer maintenance intervals.

ITM’s monitoring is standards-informed — it puts the right measurement and analytics in front of your reliability team; final limits and compliance determinations rest with the vessel, its OEMs, and its class society.
