Predictive
Fuel Actuator Command Percentage and Intake Manifold Pressure
Alert Type: Prescriptive Alert with Advanced Conditions Alert
Scenario
High-pressure diesel fuel pumps can fail suddenly, ejecting metal and causing severe engine damage. By modeling normal behavior and anomalies, we discovered thresholds of multiple sensors which are accurate predictors of impending pump failure. The formula is converted into an advance prescriptive alert which runs continuously, predicting when the pump is likely to fail.
Outcome
Western Towboat has gone from multiple failures per year with high-pressure fuel pumps to ZERO pump failures in four years.
Bearing Overheat
Alert Type: Prescriptive / Predictive Alert
Scenario
A commercial vessel had the main engine overheat at the dock. The crew was not able to detect the overheat. MarineInsight caught a series of sensors exceeding prescriptive thresholds and automatically alerted the crew, both on the vessel and onshore. This series of alerts enabled full root cause analysis by the operator and prevented catastrophic loss.
Outcome
The two prescriptive alerts that were automatically triggered by MarineInsight allowed the crew to power down and prevent damage to the engine. An investigation afterward showed that the vessel was docked incorrectly, causing back pressure on the exhaust, which triggered the prescriptive alert. Had the MarineInsight alert not been addressed, the results could have been catastrophic. Using MarineInsight reporting function, the crew was able to further investigate the water temperature overheat condition and verify that the bearings had not been compromised. Further work by the ioCurrents data science team found a method to detect similar conditions even earlier, in order to add more response time and protect key components, such as the main engine bearings.
Sensor Failure
Alert Type: Prescriptive Alert
Scenario
This alert was triggered onboard a multipurpose cargo ship when the A6 Exhaust Gas Temperature sensor showed signs of failure shortly after departing port on the west coast of the US for Asia. The alert (Fig.4-2) in red is automatically triggered at 18:52 to 20:17. This alert identified a sensor failure that the crew was unaware of, and if left unaddressed could potentially lead to loss of propulsion and power.
Outcome
MarineInsight was installed onboard only a few days before this sensor failure was captured. The onboard engineers are now able to recognize potential sensor failures, immediately identify the exact sensor in question, and replace them before critical engine readings are compromised and shutdowns occur.
Fuel Type Change
Alert Type: Prescriptive Alert
Scenario
A fuel change alert was raised to notify the shoreside team that the vessel was switching from low sulfur fuel back to HFO (Heavy Fuel Oil). This type of alert uses the main engine fuel temperature to identify if a vessel is in compliance with the ECA (Emission Control Area).
Outcome
The vessel has a timestamped and GPS tagged dataset to prove compliance with fuel type within the ECA. Furthermore, the ability to cut trips within the report and summary based on fuel type helps internal accounting teams with better granularity for fuel consumption.
Cargo Monitoring and Tank Alerts
Alert Type: Prescriptive Alert
Scenario
Customer had a problem with maintaining a constant temperature in their refrigerated saltwater (RSW) tanks. Without the remote monitoring, the solution was to track temperature in cargo tanks every six hours into their engine logs. Months after a delivery from the commercial fishing vessel, the buyer disputed the temperature claiming that the catch was above acceptable temperature range. To maintain the relationship with the buyer, the fishing company absorbed the cost. Once MarineInsight was installed, sensors from the RSW refrigeration were monitored and alerts were set.
Outcome
With MarineInsight, RSW tanks are set with prescriptive alerts. MarineInsight was able to alert the crew to show the tanks did drop below market thresholds, preventing freezing and spoiling of fish eggs.
Since MarineInsight was installed, the commercial fishing company had another claim that fish was delivered above market temperature. Since MarineInsight keeps all historical data in the portal, the fishing company was able to pull reports to show the temperature at the point of purchase, over six months in the past. The data showed that the buyer backfilled the tanks with warm water to offload all the fish, which is why the catch was above market temperature. With the available historical data, the fishing company was able to save their profits and maintain their relationship with the buyer.
Geofencing Solutions
Report Type: Automated Alert and Report
Scenario
Customers have asked for different solutions when it comes to geofencing on their voyages. There have been problems with dispatch, pilotages, tracking vessels, and time in port with the current, manual system of vessel tracking.
Outcome
MarineInsight input customer locations, based around your business needs. When a vessel crosses a point of interest, a mile marker, geofenced location, MarineInsight can generate alerts to notify you when this takes place. When a Towboat in the Inland waterways passed a certain mile marker, MarineInsight will trigger an alert to the dispatch department to ensure timely delivery and pick up at their docks. This can free up hands and provide a more accurate account of what is taking place during the voyage and reduce wasted time.
Georeferenced Summary of Alerts
Report Type: Alert Report
Scenario
Engineers, managers, and executives have requested to see a report that will help identify when vessels go into alert condition or alert status. Not only when the vessel was in alert state, but what conditions the vessel was operating in and where on the trip the vessel was traveling.
Outcome
MarineInsight will generate custom reports to show operators and managers where the vessels were operating to generate and alert. The Alert Report will give a summary of what piece of equipment on which vessel went into alert. This will help identify trouble areas on the water and help understand why vessels may go into alert and how to help operators and captains reduce their likelihood of operating in dangerous conditions.
