Mission
To offer integrated, high-performance solutions in Offshore Electrical, Electric Motors and Diesel Engines, as well as industrial automation and instrumentation.
Since 2016 delivering integrated, high-performance solutions for the energy industry.
Founded in 2016, Hollinspec was born from the experience of professionals who spent their careers inside substations, machine rooms and platforms. That origin shaped how the company works: little loose theory, plenty of verifiable delivery.
Today we operate in the energy, mining, oil and gas sectors, with facilities strategically located in Macaé, São Pedro da Aldeia and Porto do Açu, in the state of Rio de Janeiro — the three hubs that concentrate Brazilian energy operations — and an office in Fleming Island, Florida, for international service.
From the parametrization of a protection relay to the complete commissioning of a system, the commitment is the same: deliver the service with traceability, documentation and safety.
