Euronav’s IoT Solution Connects Vessels to Shore, Improving Efficiency and Reducing Carbon Emissions

Euronav is the largest independent publicly listed crude oil carrier in the world and is committed to making their fleet net-zero by 2050. Codit was approached to make this happen using IoT and cloud technology.

The Challenge

Euronav, a market-leading crude oil carrier, is dedicated to making the tanker industry more responsible and sustainable. They decided to pioneer digital transformation using smart IoT technology. The goals include: further improving safety and environmental protection, increasing energy savings of the ships, reducing fuel consumption and carbon footprint, saving on vessel Operational Expenses (OPEX), improving collaboration and overall efficiency, and designing a path to Zero Emission targets by 2050.

Of all global industries, shipping has been the one to focus on cost. Euronav is interested in gaining a competitive advantage by reducing costs, but their vision is far greater: Euronav has set out to be a digital technology leader, connecting sensors to all parts of their vessels and collecting data on the ships and in the cloud.

By gaining insights from this data, captains and management on shore can increase the efficiency of the vessels. Through aligning their tech, business and environmental goals, Euronav remains an industry leader.

Expected short-term results include a decrease in onboard fuel consumption, optimization of operations and better ship-shore-ship communications.

The challenge involved creating an IoT platform that would run both on the vessels and in the cloud. Communication with ships in oceans across the globe can suffer from poor connectivity, high network latency and connection drop-outs. Therefore, the solution had to be robust enough to allow for intelligent data exchange between vessels and shore. There needed to be one source of truth for the data – the cloud.

Of course, when high volumes of potentially sensitive data are processed, the solution also needs to be designed for security from the ground up.

Euronav is investing in digital transformation to become one of the front runners in innovation within the maritime industry, allowing us to make data-driven decisions and increase energy savings.

The Approach

Euronav started an ambitious project called FAST (Fleet Automatic Statistics & Tracking). FAST was to be a centralized platform that uses data from ships for real-time analysis of multiple metrics, coming from machinery on oil tankers. The platform’s main purpose is to allow for data-driven decision making.

It became clear early on that the collection of real-time, reliable sensor data is key to the project. In other words: using Internet of Things technology.

As a Microsoft client, Euronav was already making use of the Microsoft Azure cloud platform. Codit was chosen as a partner for the IoT development. Being a Microsoft Gold Partner with a lot of experience and expertise in IoT backend development, Codit was the logical choice. Moreover, Codit had proven experience in other maritime industry-related implementations.

The solution uses IoT sensors that collect metrics from engines, cargo tanks, bunker tanks, navigation systems, weather and so on. The vessel’s data goes through a central “data collector” onboard, which transforms, stores and publishes the data to the cloud. This is done using Microsoft Azure IoT Edge.

The telemetry that we collect on board the vessels is transmitted to the cloud, where it eventually ends up in Azure Data Explorer. Azure Data Explorer is capable of ingesting the vast number of metrics received from vessels with low latency.

The solution is designed with a microservices architecture, which means that it consists of multiple components that are self-contained and can be deployed separately. On the vessel, Codit uses a lightweight Kubernetes cluster to orchestrate the containers that are deployed there. Azure Arc is used to establish a central management plane for all the Kubernetes clusters. The next step is to get container images from ship to shore and back, which can be quite a challenge.

Euronav had already accelerated the roll-out of new Iridium Certus fleet antennas. These provide a constant flow of data from the vessel to shore locations. Although vessels are connected to the Internet 95% of the time, that doesn’t say anything about connection quality.

Part of the solution came from Codit’s special relationship with Microsoft. They happened to be working on a connected version of the Azure Container Registry and provided Codit with the opportunity to participate in a private preview. This enabled Codit developers to install an on-premises container registry on the vessels, which is linked with an Azure Container Registry instance (read more about this in our blog post).

The solution also uses Azure Service Bus to communicate with the vessel and Azure Monitor and Container Insights to collect logs and use them for alerts if things go wrong.

Apart from all this technology, the data ends up in Euronav’s FAST platform for processing. The platform can instantly analyze the condition and performance of the vessel, such as fuel consumption, and show it to personnel both on- and offshore. Additionally, onboard engineers can add events and additional information to the data in order to enrich it. However, sensor (raw) data is preserved for data analysis when needed.

This is done using both Azure Data Explorer’s powerful Kusto Query Language for hot data, and Azure Synapse for archived data.


The FAST platform helps Euronav on its journey to becoming more sustainable and efficient. As well as saved voyage costs, there is also a reduction in fuel consumption, which could add up to about 1 to 2.000 dollars per day per vessel. On top of this, there are also significant savings in CO2 emissions and other greenhouse gasses. There are many other benefits too, including predictive maintenance, shorter waiting times at the quay, and reduced claims.  

Moreover, with a better line of communication between vessel and shore, there is less need for captains to write time-consuming reports, allowing them to focus on their core task of ship management.

The FAST platform (Fleet Automatic Statistics & Tracking) gives Euronav a competitive advantage in the shipping industry. Patrick Declerck, Operations Manager at Euronav, highlights the impact of the platform on efficiency gains, ensuring tangible benefits for the company and society. The expertise gained through the FAST platform enables Euronav to enter new shipping segments and diversify their fleet, while ensuring efficient operations and addressing sustainability challenges. 

In order to accelerate the digitization of the sector, Euronav has also joined forces with ZeroNorth, helping it to integrate FAST into its platform to offer digital algorithms and solutions for the maritime industry. 

Moving forward, they will certainly build on their current experience in data analytics. Teams in Antwerp and Athens are already developing new dashboards, reports, and insights. An important result is a reduction in the use of fuel oil, contributing to the organization’s goal of achieving zero emissions by 2050. Other results of the data collection and visualization are increased safety, environmental protection performance, and lower Operational Expenses.  

The platform also improves the collaboration and communication between vessel and shore. Euronav hopes that this will involve the crew more in the decision-making process and create a feeling of inclusiveness in the Euronav family – wherever they are in the world. 

A word from the client

“If there is anything that will happen in our industry, it's an acceleration towards more data, more technology and better use of this data and these technologies by people who are very experienced. When you match or when you marry the two together, then you have the best outcome.”
