Italian classification society Rina has acquired the entire share capital of US infrastructure, transport and renewable energy firm Patrick Engineering.

The Chicago-based company has annual revenue of $82m and employs around 340 people at 19 offices mainly around the US North East.

Patrick Engineering will be integrated into subsidiary Rina Consulting.

Rina, which recently revealed plans to grow by 50% by 2024 and to double its profits, said the acquisition is part of its policy to grow organically and increase its global footprint.
