How Marinminds monitors yacht health and performance

Updated: Sep 21, 2021

Marinminds monitors the performance of yachts under management to make sure they are performing like they should and are always ready for departure.

At a time when remote work is the new normal, Marinminds steps up the game of yacht management and checks the performance of yachts remotely.

Currently, most yachts are being annually serviced. During this annual service, scheduled maintenance of onboard systems is performed according the handbook, a good mechanic subsequently checks all systems on irregular and abnormal behaviour and decides (with owners consent) if parts are being changed to lessen the likelihood of failure and preventing it from breaking down unexpectedly: hence preventive maintenance.

Marinminds now takes this preventive maintenance a step further by not waiting until the annual checkup or breakdown, but proactively search for changes in system behaviour which in turn may result in breakdown.

How does this work?

  • The Marinminds Connect Hub is installed aboard: a piece of hardware; a data logger that is connected to the cloud.

  • The yacht is monitored remotely, anomalies and changes in system behaviour are detected automatically (through machine learning) or by an engineer who's analysing the ships performance manually.

  • Via a mobile app the owner or captain sees the yacht's status and is informed when action is to be taken.

  • With the owners consent the required work is executed and coordinated by Marinminds. If in depth analyses is required, the issue is diagnosed with historical data at hand.

  • The result: a healthy yacht, ready for departure.

Real-life example: propulsion performance

Let's take a closer look at this case "from the field" (or rather "from the sea").

As part of our Digital Yacht Crew service we monitor propulsion performance over time. The benefit of monitoring a twin engine yacht is that we are able to compare the performance of both engines to each other.

In this case our algorithms noticed a slight difference in engine fuel pressure. With the port engine continuously running on 0.5 bar and increasing over time up to 1 bar more fuel pressure than starboard engine, running at the same engine revolutions. This (obviously) resulting in a slightly higher fuel rate of around 3-5 liters/hour more.

Yacht twin engine fuel pressure and fuel rate

Marinminds is adding more and more yachts to its portfolio. The benefit of having multiple yachts is lots of data; with every yacht added we gain more knowledge about the proper working of its systems and components. We are able to compare systems and components of different ships to each other.

Fuel pressure of various engines compared

Comparing the engine data to similar engines from other yachts, running in the same conditions we see that the port engine of the respective yacht is clearly the outlier. We also see that both engines on other twin engine yachts run very similar.

(Next time more sophisticated parameters and algorithms we use to monitor propulsion performance over time.)

All hands on deck?

Not quite; there is no urgent need to call the owner and stress him with problems. As part of our yacht management service we contacted the engine supplier, sending him a detailed report of our findings. On their advise we scheduled an extra check once the yacht is back to it's homespot. In the meanwhile we created an extra alarm on the fuel pressure data: might the discrepancy increase further, our personal yacht manager is immediately informed by the system.
