Shipping companies face a significant challenge – the need to reduce carbon emissions on a global scale while staying competitive on the market.
Fleet performance management and digitalization play a key role in optimizing operational measures by monitoring efficiency, ensuring compliance with upcoming regulations, and streamlining onboard reporting.
Given the upcoming regulations, it is vital to understand a ship’s performance and predict its behaviors in various situations while striving for environmentally friendly fleet operations.
In this article, we will briefly discuss how you can:
- Optimize Fleet Performance through Streamlined Data Collection
- Ensure Data Quality
- Use Data for Monitoring and Optimization
- Improve Performance with Alerts
- Work with Automatic data acquisition
Optimizing Fleet Performance through Streamlined Data Collection
Effective analysis and decision-making depend on reliable data. This is where on-board data collection and data preprocessing play a significant role in the entire process.
Automatic data collection systems, comprised of both hardware and software, continuously gather, process, and transmit data from a ship’s systems and sensors in real-time. This optimization enhances performance and safety for both on-board and onshore teams.
The data collector works by continuously gathering, filtering, processing, and storing data in real-time, with adjustable frequency settings. It further enriches this data by integrating external sources like weather data and manual inputs from the crew.
Here are some examples of relevant data to collect:
- Fuel consumption rates: Monitor the ship’s fuel usage over time, including consumption per hour or per nautical mile. Analyzing this data identifies trends and optimizes fuel efficiency, saving costs and reducing environmental impact.
- Engine performance data: Includes power output, fuel combustion efficiency, temperature, pressure, and RPM (Revolutions Per Minute). Monitoring these parameters helps you detect issues early, schedule maintenance proactively, and ensure peak engine efficiency.
- Navigation and route data: This data category involves capturing the ship’s course, speed, and planned route. It helps in optimizing voyage planning, reducing fuel consumption by choosing the most fuel-efficient routes, and ensuring vessels arrive at their destinations on time.
- Weather conditions and forecasts: Information about wind speed, direction, wave height, temperature, and precipitation are crucial for maritime operations. It helps you make informed decisions, adjust routes, and ensure the safety of the crew and cargo.
- Maintenance and machinery data: Involves collecting information on ship systems and machinery, including engine maintenance records, machinery operating hours, and equipment status. Regular monitoring ensures scheduled maintenance, reducing breakdown risks and optimizing reliability.
- Emissions and environmental impact metrics: Focuses on tracking ship emissions, including greenhouse gases and other pollutants. Understanding emissions data is crucial for compliance with environmental regulations and reducing the vessel’s environmental impact, contributing to sustainability goals.
Ensure Data Quality
Maintaining sensors and ensuring data quality is essential. Identifying data anomalies can be challenging, as unreliable data cannot be used for analysis until sensor issues are resolved. To ensure your data is reliable, it is crucial to have a process in place for timely intervention:
- Define automatic alerts generated by the performance system.
- Regularly analyze data to detect implausible information that may have been missed by automatic alerts.
- Once issues are confirmed, plan for onboard sensor calibration or replacement.
Additionally, onshore systems should offer tools that make it easy for you to manage the first two steps effectively.
Use Data for Monitoring and Optimization
Real-time monitoring of vessel operations enables cooperation among stakeholders, onboard and onshore, enhancing crew awareness and leading to better vessel operations and fuel savings.
On the other hand, performance monitoring enhances consequent fuel saving and transparency between ships, shores, and business partners. It is the key to unlocking hidden energy-saving opportunities.
For example, to handle complex systems that are meant to ensure compliance like scrubbers, you need to be able to monitor, assist the vessel, and act on time.
Improve Performance with Alerts
Alerting capabilities are vital in performance monitoring, identifying missing or implausible data, and aiding both onshore and onboard operators in improving vessel operations and regulatory compliance.
When an alert is generated, the system sends emails both onboard and ashore, warning you about critical situations.
Examples of alerts:
DG MCR Alert
Crews tend to run extra Diesel Generators (DG) at low Maximum Continuous Rating (MCR) for safety, resulting in unnecessary fuel consumption. The alerting system improved onboard practices by monitoring and correcting inefficient DG usage.
This alert, detecting DGs and their MCR, was implemented in two companies, with positive outcomes: fewer alerts over time in the first case, and stable alerts despite increasing installations in the second.
Alerts do not only allow to promptly react to an event but have proven useful to create good habits onboard and to be a successful tool to enforce company procedures.
Work with Automatic Data Acquisition
Traditionally, noon reporting relied on daily manual data input to collect vessel information across operations. However, evolving market conditions and new regulations are driving the adoption of automatic data logging systems on modern vessels.
The top picture represents the results of the analysis of a propeller change obtained on data collected manually, while on the bottom the results on data automatically collected on board are presented.
With noon report data, assessing the retrofit’s benefits seems impossible, whereas data collected automatically confirms overall improvement in hydrodynamic efficiency. Quantifying such improvements benefits your technical operations.
Data-driven Performance Management
In the pursuit of decarbonization and enhanced fleet performance, effective data collection and analysis are essential.
Shipowners and management companies face the challenge of reducing carbon emissions globally, making performance management and digitalization pivotal in achieving operational efficiency and regulatory compliance. Streamlined data collection, automatic data logging systems, and the integration of various data sources are vital components of this process.
In our quest for efficient, eco-friendly maritime operations, there are key data categories we must focus on. However, it’s not just about collecting data; it’s about nurturing its quality through sensor maintenance and calibration.
Moreover, we must recognize that real-time monitoring, performance alerts, and collaboration between stakeholders are the wind in the sails of operational optimization and cost-saving.
