The vessel does not have to stop completely for downtime to start costing you.

A gearbox running hot.
A thruster that is becoming harder to support.
A hydraulic issue slowing down deck operations.
A control or integration problem that keeps returning.
A spare part that is taking longer than expected to source.

For many vessel operators, the challenge is not always a major failure. It is the accumulation of smaller issues across ageing fleets, complex systems and support gaps that gradually affect availability, reliability and operational capability.

And when the vessel cannot work as planned, impact is felt quickly.

Lost time.
Lost productivity.
Lost confidence in the next operational window.

That is why lifecycle support matters.

MIT works with vessel operators, boatbuilders and fleet managers to support marine drivetrain, propulsion and auxiliary systems across the full life of the vessel.

From specification and supply through to installation, commissioning, planned maintenance, overhaul, fault finding and OEM parts support, our role is to help keep vessels operating reliably and efficiently.

Because when systems are not properly integrated, maintained or supported, downtime becomes more than an inconvenience.

It becomes an operational risk.

At Seawork 2026, our team will be on hand to discuss the challenges operators are facing now and how MIT can support vessels across commercial marine, workboat and offshore applications.

Whether you are managing an ageing fleet, planning maintenance, dealing with drivetrain reliability issues or looking for better support across propulsion and auxiliary systems, speak to our experts.

The driveline does not just move the vessel.

It drives the work.

On many commercial vessels, the driveline is not only about propulsion. IIt also powers hydraulic pumps, winches, deck machinery and auxiliary systems that keep the vessel productive every day.

That is where the Twin Disc, Inc. PFI 60 comes in.

The PFI 60 is a rugged-duty hydraulic PTO designed for high-horsepower applications, helping deliver reliable power to the critical systems vessels depend on every day.

Compact yet powerful, it features a multiple-disc oil bath clutch, hydraulic actuation with a 24V DC solenoid selector and flexible mounting options, including engine, remote, pump drive input/output or free-standing setups.

Available with SAE 1, 2 or 3 housings, the PFI 60 supports cylindric or splined shaft connections and external oil cooling, giving operators reliable, versatile performance in demanding environments.

In simple terms, it is built to deliver power where the vessel needs it.

Because when auxiliary systems stop, the vessel may still be able to move, but the work stops.

Winches cannot pull.
Hydraulics cannot hold pressure.
Deck systems cannot operate.

The result is not just a driveline issue; it is lost working capability.

The Twin Disc PFI 60 is not just about keeping vessels moving; it is about keeping them working.

What should be in place before something fails?

Planned maintenance.

Not because something has already broken, but because most gearbox failures start long before operators see obvious symptoms.

MIT recently completed a scheduled overhaul on a Twin Disc MGX5114 marine gearbox. Once the unit had been stripped and inspected, debris was found within the suction strainer, while wear was also identified on clutch components, the oil pump and seal running surfaces.

None of those issues had yet caused major failure.

That is the value of planned inspection work. It gives operators visibility into the condition of the drivetrain before wear starts affecting reliability, availability and operational schedules.

We saw similar themes during the overhaul and reinstallation of Reintjes WAF163 gearboxes onboard a crew transfer vessel, where alignment work, onsite fault finding and final sea trial support all formed part of the wider job.

In practice, reliable propulsion systems depend on far more than the gearbox itself. Alignment, installation quality, mounting condition and system integration all play a part in long-term performance.

Whether supporting Twin Disc or Reintjes gears, the objective is ultimately the same: identifying wear early, planning intervention properly and reducing operational disruption wherever possible.

Because the best time to deal with wear is before it becomes failure.

Pilot and patrol vessels depend on response.

Fast engagement.
Smooth manoeuvring.
Reliable control.
Predictable handling.

MIT Marine Sales and Product Manager Keith Stevenson discusses why MGX marine gears are trusted in demanding commercial vessel applications.

A gearbox does more than transfer power from engine to propeller. It plays a major role in how a vessel feels, reacts and performs when it matters.

For high-duty vessels, the right gearbox specification is critical.

Duty cycle.
Engine package.
Control requirements.
Operating profile.
Available space.
Lifecycle support.

Keith also looks at how EC600 integration can help manage clutch engagement and vessel response with greater precision, helping crews operate confidently in tight, fast-changing conditions.

Because for pilot and patrol vessels, performance is not just about speed.

It is about control.

Today we organised a small summer treat for the team at our HO, with an ice cream van stopping by to give everyone the chance to step away for a while, catch up and enjoy the weather together.

It feels a little bittersweet as we head into our last summer at this site before moving to our new Walbrook location later this year, while continuing our journey in Queenborough.

Moments like these are an important reminder of the people behind the business and the culture we continue to build across every stage of our journey.

A successful dry dock starts before the vessel reaches the yard.

The more you know ahead of docking, the better you can plan the work, parts, tooling and support needed once the vessel is out of service.

That is why pre-dock preparation matters.

For a planned LufkinHS2800 gearbox overhaul, MIT’s preparation started with reviewing the vessel’s operational history, vibration logs and oil analysis trends. This helped build a clearer picture of the gearbox condition before the dry dock window began.

From there, the project could be planned properly.

Tooling lists were prepared.
OEM torque values were confirmed.
Required OEM bearings, seals and gaskets were procured.
PTO coupling and clutch system seals were planned.
Consumables were confirmed to OEM specification, including ISO VG220 / AGMA #5 gear oil.
Lifting plans and rigging certification were coordinated with the shipyard.
A risk assessment and clear project plan were put in place before work began.

Early preparation helps reduce uncertainty and gives maintenance teams better control before critical dry dock work begins.

The strongest dry dock projects start with early condition monitoring, operational reviews and proper planning for OEM parts, tooling and safety requirements.

While pre-dock planning cannot remove every unknown, it allows projects to move forward with greater control from day one — which is where MIT’s experience delivers the greatest value.

A workshop rebuild should never be a guessing exercise.

When a marine gear, clutch, torque converter or MCD transmission comes into our workshop, the first stage is not deciding what to replace.

It is understanding the condition of the unit.

That means stripping it down, cleaning the components properly, and inspecting the internal parts before any repair route is confirmed.
We assess:

What can be reused?
What has reached the end of its service life?
What needs replacing to return the unit back within specification?

This MCD 3000-3 HD overhaul is one example of that process in practice.

In this case, the unit was fully stripped, cleaned and inspected before being rebuilt with new bearings, seals and clutch components.

Serviceable parts were retained where appropriate, and worn items were replaced where required.

The oil system was also flushed and refilled, helping protect the rebuilt unit from any remaining contamination in the lubrication circuit.

Because a rebuild is only as reliable as the process behind it.

Replacing parts is one stage.

Cleaning, inspection, correct assembly, oil system preparation and commissioning are what turn that rebuild into a dependable repair.

Once the gearbox was back together, MIT supported the commissioning process and pre-sea trial checks.

The MCD was confirmed operational.

The vessel then completed a successful sea trial, with pressures, temperatures, speeds and control parameters all within specification.

That is the real outcome of a workshop rebuild.

Not a box of new parts.
Not a quick repair.
A transmission that has been assessed, rebuilt, tested and proven before returning to service.
