Introduction:

Terminals play a crucial role in the global logistics chain, ensuring the efficient transfer of goods between ships and land-based networks. A notable trend within these infrastructures is the relentless pursuit of operational efficiency. This continuous quest for improvement stems from several factors, including the exponential growth of international trade, the increase in the volume of handled goods, and the need to reduce production times. Terminals strive to optimize their processes to expedite ship loading and unloading, minimize waiting times, and enhance overall productivity. This trend also arises from the escalating competitive pressure among ports, prompting operators to adopt innovative technologies and advanced logistic practices to remain competitive on the global stage. Thus, efficiency becomes a cornerstone in the management of Terminals, driven by economic and logistical imperatives.

While Terminals are actively pursuing operational efficiency, there is a parallel challenge associated with the lack of standardized metrics. Despite the emphasis on optimization, the absence of universally recognized standards makes it challenging to accurately assess and compare the efficiency levels of different equipment within the Terminals. This lack of standardized metrics can impede efforts to identify best practices, hindering the industry's ability to collectively address inefficiencies. As terminals strive for enhanced efficiency, there is a concurrent need for the development and adoption of comprehensive and standardized metrics to effectively gauge and improve their operational performance. This dual focus on efficiency enhancement and metric standardization highlights the complexity of managing and benchmarking performance within the dynamic landscape of port operations.

From an operational perspective, the need for standardized efficiency metrics in port terminals is crucial for streamlining processes and benchmarking performance. Consistent metrics allow terminal operators to identify bottlenecks, inefficiencies, and areas for improvement. It facilitates a more transparent evaluation of operational effectiveness, enabling terminals to implement targeted strategies to enhance productivity. This fosters a culture of continuous improvement and ensures that operational efforts are directed towards universally recognized objectives.

From an equipment health perspective, the need for standardized efficiency metrics in port terminals is paramount for ensuring the well-being and longevity of the machinery and technology deployed. Standardized metrics provide a systematic approach to monitor the health and performance of equipment, allowing for timely identification of potential issues. This proactive stance enables maintenance teams to implement preventive measures, reducing the risk of unexpected breakdowns and minimizing downtime. By having consistent metrics, terminal operators can establish baseline performance levels for each piece of equipment, facilitating the creation of maintenance schedules and predictive maintenance strategies.

For equipment teams standardized metrics serve as a valuable tool for designing robust and resilient machinery. Understanding the operational benchmarks enables technical teams to optimize equipment maintenance and or design, and implement features that enhance reliability. These metrics act as a feedback loop, informing teams about the real-time performance of equipment and guiding them in refining future priorities.

This alignment with standardized efficiency metrics ensures that equipment is not only efficient in terms of operational productivity but also sustainable and capable of withstanding the demands of continuous usage in a port terminal environment. Ultimately, the integration of standardized metrics from an equipment health perspective contributes to the overall reliability and performance of port terminal operations.

Problem Statement

In the previous health whitepapers, we introduced:

• How health as a concept has to be used to enhance the terminal visibility

• How maintenance should play an important role to drive health

Today, the industry is missing an efficient and accurate way to provide health as measurable information. We have a variety of information that is not aggregated at present to provide both operational and technical teams with an accurate statement of the equipment health. How healthy is my machine? 70%? Can I perform the next 8 hours with that level of cargo moves without any problem?

On the other hand, the way to process the data in order to be able to calculate and reflect the health of a piece of equipment or a fleet is not yet clearly defined.

How can TIC4.0 improve value?

To enhance Terminals capabilities, we already created two data models. We started with the CHE health data model and we later added the Maintenance data model to empower the health information with the reality of maintenance tasks.

CHE data model structure to ensure health calculation

Now 'we talk health' and we have the prerequisites regarding which data we need to process the health, however we still have to progress and bring health to the next level: being a metric information.

To do this, we first need a conceptual insight, as a reminder.

The CHE data model has been built to monitor all equipment activities. All the actions such as hoist, trolley, gantry and others are considered as subjects. All those subjects are ‘parents’ for their concepts.

Open

Focusing on the health subject, we observe the concept healthy as below

The advantage of the data model is not only its flexibility but also the infinite measurability it can offer. This concept of healthy could be repeated for different subject. So, from the data model point of view, the solution to bring health to the next level is to copy this concept within every subject. We will then be able to have:

• How healthy is my straddle carrier hoisting?

• How healthy is my spreader?

Signals need to be well processed in order to deliver a valuable interpretation & results. Thanks to CHE data model and its flexibility, we managed to integrate healthy in every subject.

Thanks to the data model arrangement and flexibility, we automatically have the right way to classify the information that is coming from different signals and we are thus able to organize the health calculation process accordingly.

What is the healthy level?

TIC 4.0 aims to represent any reality in digital format. The way to represent an instantaneous reality (a frozen image of reality) is through the “status” (position, speed, etc.) in a specific timestamp.
(e.g. at 06-10-2023 09:00 Straddle Carrier 01 is working bay 01A 02 01 and driving with speed of 10 km/h)

In the KPI whitepaper, we defined:

‘KPI = Represents in a consolidated way a reality, during a period of time, filtered, grouped and split in such a way that allows the reader to understand it is creating value.’

This is exactly what health level has to achieve. Being a value that represents the CHE state of health. This value, thanks to the data model flexibility, can be utilized in every systems and subsytems (concepts) of a CHE.

Healthy is a scalable concept that could also be used to measure a process such as the following examples:

• Operation layers (planning, execution) → ‘How Healthy am I in the dispatching? How often am I cancelling a job instruction?’

• Preventive maintenance → ‘How healthy is my right on time maintenance? How healthy is my scehduling process? Is the workforce intervention healthy?'. As we introduce in the previous white paper, we introduce new concepts in the maintenance data model where healthy as a concept could be introduced as well to ensure maintenance performance & reliability measurement through Health.

Get Health as a KPI should be seen as a functionnality. We have to handle and standardize the way to process and compute the information to achieve our calcluation goal.

As per the definition, health concept is declined in sub concepts that allow to understand the machine behavior. These concepts are:

• Error

• Warning

• Fault

• Interlock

The health monitoring process is a collaborative effort involving multiple sources and team members, each contributing their expertise to ensure the optimal health, performance, and reliability throughout the dynamic challenges of the Terminal efficieny.

What is impacting healthy level?

The health level monitoring involves a sophisticated systems of real-time telemetry and data analysis. Here's an overview of how monitor the health:

• Operational Data:

  • Operating hours – to be compared with equipment lifecycle

  • Breakdown status (if stopped frequently, it might indicate wider issues)

• Telemetry data:

  • Sensor, alarms such as temperature, tyre pressure, encoder error.

• Maintenance History:

  • Time since last maintenance

  • Work Orders pending (criticality and quantity)

• Performance Metrics:

  • Efficiency and downtime duration

• User Feedback:

  • Feedback and reported issues from operators

• External Factors:

  • Environmental conditions

• Predictive Analysis Data:

  • Adopting predictive analytics and machine learning algorithms to anticipate potential issues based on historical data. This helps in proactive decision-making and preventive measures

• Preventive Maintenance Score Determination:

  • The score will be determined and rate based on:

  • If the maintenance was done on time = best score

  • If the maintenance is due within the next week

  • If the maintenance is overdue by a week

  • If the maintenance is overdue by two weeks to a month

  • If the maintenance is overdue by more than a month

The Error | Warning | Fault | Interlock process is crucial. Terminals has to set up a robust and sustainable alarm systems to alert technical teams when certain parameters deviate from the expected values. This proactive approach allows teams to identify potential issues before they escalate.

Advanced telemetry ensuring health monitoring enables remote diagnostics, allowing engineers to assess the health of specific components without physically inspecting the equipment. This is particularly valuable during realtime operation to avoid any downtime.

Displaying crucial informations represents also a key point to ensure the operational efficiency monitoring. Health is a concept that will drive the performance.

How health evaluation scale could be?

Equipment Health Scale (EHS) could be:

0-20: Critical (Immediate attention required)

21-40: Poor (Maintenance or check-up needed soon)

41-60: Fair (Operational, but monitoring required)

61-80: Good (Healthy operational state)

81-100: Excellent (Optimal condition)

The possibility to move into an ecosytem that includes hundreds of data and advanced computing functionnalities is only possible if Health concept is applied and spread over the CHE and process. TIC already shares the CHE Health and Maintenance data models & defintions that represents the first briks to reach the right monitoring level.
