Infrastructure modernisation at PGZ Naval Shipyard in Gdynia

The modernisation aims to increase the yard’s production capacity and improve logistical efficiency, supporting the construction of modern naval vessels, including the frigates being developed for the Polish Navy under the Program Miecznik.

The works were carried out by the Polish contractor NDI Group and covered several major projects implemented over a period of three years.

New production halls expand shipyard capabilities

A central element of the investment programme was the construction of two new production facilities: a large hull assembly hall and a production hall dedicated to steel processing and fabrication.

The hull assembly hall, reaching approximately 46 metres in height, is among the largest structures of its type in Europe. The building is equipped with large industrial gates and heavy-duty overhead cranes with a lifting capacity of up to 100 tonnes. This infrastructure enables the assembly of large hull sections and blocks under controlled indoor conditions, which improves production precision and allows work to continue regardless of weather conditions.

The second facility, a production hall with an area of nearly 5,000 m², supports the fabrication and preparation of steel structures and ship components.

March marks three years since demolition works began for the three major investment projects at the shipyard.

- The first facilities to be completed were two key buildings: the Hull Assembly Hall and the Production Hall, which already significantly increase the shipyard’s production and technological capabilities, said Przemysław Młynarczyk, construction manager at NDI Group.

Alongside the new halls, a social and administrative building was also constructed, providing modern office and staff facilities.

Logistics and storage infrastructure

The investment programme also included the construction of a warehouse hall with an area exceeding 3,300 m². The facility provides storage and logistical support for shipbuilding operations.

Extensive site development works were also carried out across the shipyard. These included the expansion and redevelopment of quays, storage yards and internal transport routes. In total, more than 50,000 m² of new surfaces were constructed, significantly improving the internal logistics and operational efficiency of the facility.

The new infrastructure facilitates the movement of large ship sections and heavy components between production halls, storage areas and the waterfront.

Modernisation of existing shipyard facilities

In addition to new construction, several existing buildings within the shipyard were modernised and adapted to current technological requirements.

Part of the A-11 hall was converted into a logistics centre and extended with a new annex housing a tracing workshop. This specialised space allows ship components designed in technical drawings to be transferred at full scale onto steel plates before fabrication begins.

Another building, A-9, also underwent refurbishment to accommodate modern production needs. Both facilities were equipped with new sanitary, electrical and telecommunications systems, as well as the necessary technological equipment.

The project presented additional challenges due to the historical nature of some of the structures, with parts of the facility dating back to 1938. Construction work had to be carefully coordinated because the buildings remained in use throughout the modernisation process.

- Thanks to this project, the shipyard has gained a significant amount of modern office space. During construction we faced numerous challenges, not only structural but also organisational, as we were working in a facility whose origins date back to 1938. Shipyard employees remained in the building throughout the works, so construction activities had to be carried out without disrupting their daily operations, Przemysław Młynarczyk added.

Strengthening Poland’s naval shipbuilding capacity

The completed investments significantly enhance the production infrastructure of PGZ Naval Shipyard and support the implementation of complex naval construction programmes.

New production halls, logistics facilities and upgraded internal transport infrastructure improve the organisation of shipbuilding processes and increase the yard’s ability to handle large-scale naval projects.

The modernisation forms part of a broader effort to strengthen the industrial base supporting Poland’s naval modernisation and to expand domestic capabilities in naval shipbuilding.
