Company History

Meaningful and actionable insights based on factual information on port operations. Delivered in frictionless cooperation.​

Here I was, Managing Director of a large tug operator, standing by the river Scheldt together with our European Head of Business Development. Our mission for that day was to explore the towage operations in Antwerp so that we could determine our entry strategy and prepare a business case for the board. Our tool: a set of binoculars…

The problem we faced at the time with any competitive entry into a new port was that there was no information available on any of the questions that you have when you want to assess the business case for doing that entry. How many assists are there, how long does an operation take, who are the key customers/segments, how many tugs do we need to service this port, et cetera?

It was then that Bert and I teamed up and set out to develop a solution that would enable Tug Operators to get accurate factual insights into any towage operation in the world, including their own.

By mid-2017, the first version of what we internally refer to as “The Job Scanner” saw the light. It is our software that seeks out towage job patterns, merely using AIS data.

Now we’re 4 years onward with 50+ ports explored in our software and a further suite of tools and use cases to help Tug Operators not only do better business development but also reduce fuel, CO2, SOx and NOx.

We feel proud that we have been able to make a positive contribution to our customer’s bottom line while also reducing the environmental footprint of their operation. A port manager of one of our customers told us – after a reduction of almost 25% in fuel consumption – that they have never seen such a low level of fuel consumption on their tugs before. And that is what drives us to do more. We want to use our expertise in data analytics and maritime to create a real impact for our customers, the planet, and our team.

Our Team

Our Expertise

Towage is your business. You operate under an increasingly competitive situation; margins are deteriorating while the demands to your fleet are increasing with larger vessel sizes. Consolidation in the market means your competitors are getting scale advantages. You’re trying to run a highly efficient operation and occasionally look for opportunities to expand. LionRock Maritime can help you with both.

Our expertise – in short – lies in drawing operational, commercial, and strategic insights from publicly available data sources for tug operators using data technology. But we don’t stop there; we support
with the implementation of these insights and ensure value is exploited.

Frequently asked Questions

How do you get market data on a port?

We get AIS data from one of the various suppliers in the market. Our own software analyses the AIS data and finds patterns between tugs and ships; cargo ships, cruise ships etc. This is the market data we use to power our insights for your expansion.

How many years can you look back / provide insights on?

As far as the AIS data allows us. AIS has been mandatory for all ships since early 2000s. But usually we make reports covering up to 3 years of history.

How accurate can your software track tugjobs rom AIS data?

We are very proud of the accuracy of our tracking software. We have done multiple verifications of the accuracy, comparing our data with actual data, and we get around 98 to 99% correct.

We usually get market information from the port authority. What can your information add?

Most port authorities will give you information on the total vessel calls in a port. That is a great start for sizing the market. However, for assessing the required number of tugs to put in, you want more detailed information about the exact number of tug jobs, the fluctuation thereof during the day/week/year etc. We provide this as well as various other insights that are needed for making an accurate investment thesis.
