Prohoc is a Vaasa-based industrial services group that manages construction, commissioning, field service and maintenance on industrial investment projects, with Wärtsilä’s Sustainable Technology Hub in Vaasa as its flagship case. The group’s head-office company is Prohoc Oy (business ID 3238185-6). Its Portuguese branch, Prohoc Oy – Sucursal em Portugal (NIF 980684960), is registered in Nogueira da Regedoura, Santa Maria da Feira, under CAE 71120 for engineering and technical consultancy.
Prohoc describes itself as a full-spectrum industrial partner that builds facilities and runs and maintains industrial production. Its work spans project and construction management from early development to start-up, specialist services, production services and a global field-service unit. The field-service unit supplies technicians and engineers to OEMs for electrical and mechanical installation, instrumentation and commissioning, automation testing and maintenance, including turnkey service for peaking power plants and marine and offshore equipment. Its main published case is Wärtsilä’s Sustainable Technology Hub in Vaasa. Prohoc supported project and construction management there and handled the transfer of assets to the new centre, and now plays a role in asset management and engine manufacturing. The group is led by CEO Kimmo Kohtamäki from Virtaviiva 8 in Vaasa. It has further offices in Helsinki and Norrköping and local contact points in the US, the UK and Guatemala.
The group’s structure changed in 2021–2022. A new company, Prohoc Oy (business ID 3238185-6), was registered in September 2021 and acts as the head-office company. The older entity, business ID 1068553-3, was registered on 16 January 1997 as Prohoc Oy and is now named Continent Finland Oy. That older entity is the parent of the Portuguese branch, which still carries the Prohoc name: Prohoc Oy – Sucursal em Portugal, NIF 980684960. The 980 prefix marks a foreign entity in the Portuguese tax register. The branch is at Rua de Sorregos 19 in Nogueira da Regedoura, in the Santa Maria da Feira municipality south of Porto, and is classed under CAE 71120 for engineering and process consultancy to manufacturing and energy clients. Prohoc’s current website does not list a Portuguese office, and no named Portuguese project has been found.
Nordic OEMs such as Wärtsilä service engines and power plants worldwide and need mobile field crews to do it. Northern Portugal, with its metalworking and industrial-maintenance labour pool around Porto and Aveiro, is a natural recruiting and staging ground. A Finnish industrial-services group with a branch registered in Santa Maria da Feira fits that pattern. Portuguese engineers and technicians can be hired under a Nordic employer and deployed on international projects. Watch for Portuguese hiring or a named project to show whether the branch is active.
