297 containers in 54 days. How we organised module logistics for solar farms with a combined capacity of 133 MW

PAD RES
Handling containers with photovoltaic modules — Port of Gdańsk

On 11 May, 86 containers arrived at the Port of Gdańsk. In a single day.

In a situation like this there is no room for improvisation. You need to know which B/Ls have already been released, how much space is left in the warehouse, which construction site needs the material most urgently and how many hours remain before container detention charges start to accrue. That is exactly what our team handled while managing deliveries of photovoltaic modules for three solar farms with a combined capacity of 133 MW, under construction in south-western Poland.

We took on the entire domestic leg of this supply chain, from the moment the vessels entered the port through to unloading at three different construction sites.

Project timeline

  • 8 May 2026First container collected from the Port of Gdańsk.
  • 11 May 2026Peak arrival: 86 containers reach the port in one day.
  • 30 June 2026The final shipment arrives at the construction site.

Three farms, one process

The modules were destined for three projects that the PAD RES Group was developing in the Opole and Lower Silesian voivodeships. Our task was not a set of individual shipments. It covered managing the entire flow of material between the port, the warehouse and three construction sites located far apart from one another.

Where the difficulty came from

The challenge was not the number of containers itself, but their uneven inflow. Vessels arrived in line with the shipping lines' schedules, but the release of B/L documents, container availability at the terminal and the pace of work at the port rarely aligned. For weeks at a time only a handful or a dozen or so units would come in, and then 86 containers would arrive at once, or a single batch of 58 units under one B/L.

Every surge called for a fast decision. In what order to collect the containers, how many vehicles to dispatch, whether the warehouse could keep up with unloading and how many hours were left before demurrage charges.

A mistake at any of these stages translated into demurrage costs, a bottleneck at the warehouse or a delay on site. That is why the whole chain had to be treated as a single system rather than a series of independent transport orders.

On top of that, the containers arrived from different shipping lines, each with its own rules for releasing documents, different free-time windows and a different way of calculating charges. Instead of dealing with every shipping line, terminal, warehouse and carrier separately, our team took over the whole thing, tracking deadlines and statuses with each of them on an ongoing basis.

Containers handled as part of the project arrived with shipping lines including MSC, COSCO Shipping, CMA CGM and Charter Link.

What we did day to day

  • We monitored vessel arrival schedules and responded to changes.
  • We kept track of B/L document releases and free-time deadlines.
  • We planned the order of collections from the port, reducing the risk of demurrage and detention.
  • We arranged the transport of containers from the port to the warehouse.
  • We coordinated the unloading and storage of the modules.
  • We planned releases from the warehouse in line with the real needs of each of the three sites.
  • We loaded the goods onto standard trailers and organised 297 deliveries to the project locations.
  • We stayed in constant contact with the warehouse, the carriers and the contractors.

The warehouse as a buffer

After collection from the port, the containers went to the warehouse, where they were unloaded. The warehouse separated two rhythms that could not otherwise be reconciled: the irregular, surging inflow of sea shipments and the steady, planned demand of three construction sites.

Large batches of containers could be collected from the port quickly, with no standstills caused by a lack of space. The construction sites received smaller, tailored batches, matched to what the crews actually needed in a given week rather than to the order in which the vessels had arrived.

Outcome

What this project meant for the client

One team instead of four contacts

Instead of separate conversations with shipping lines, the terminal, the warehouse and the carriers, a single point of contact responsible for the entire process.

Visibility at every stage

From a vessel entering the port, through collection and storage, to a specific delivery to a specific construction site.

Lower risk of extra costs

Keeping an eye on free time and prioritising collections with demurrage and detention in mind.

Deliveries paced to the build

The warehouse released material when it was genuinely needed on site — not to suit the vessel schedule.

Less operational work for the contractors

The crews could focus on building the farms rather than on coordinating logistics.

Not one site was left waiting

Despite the container surges and three delivery addresses, logistics never became the bottleneck — that was the main goal of the assignment.

Photos from the project

This is how we see the role of a logistics operator

In 54 days we collected 297 containers from the Port of Gdańsk, arriving on 15 vessels with several shipping lines, coordinated their unloading and storage, and then organised 297 shipments to three construction sites in two voivodeships, working with two main contractors. Handling this volume was not a matter of ordering one truck run after another. It was a single project in which vessel schedules, documentary deadlines, warehouse capacity and the needs of three construction sites had to work as one mechanism.

This project brought together the capabilities you will find across our services: sea freight forwarding with B/L document handling and free-time management, warehousing acting as a buffer between the port and the sites, and road transport delivering to the construction sites.
