About this case
Introduction
Lisnave is a Portuguese ship maintenance and repair company serving customers from more than 50 countries. At its shipyard in Mitrena, near Setúbal, the company repairs and maintains vessels ranging from tankers and container ships to LNG carriers, offshore vessels and cruise ships.
Looking to increase the speed and quality of its spool manufacturing process, Lisnave invested in HGG’s ProCutter 900 in 2023. The result: faster cutting, cleaner and more precise parts, less cleaning and quicker assembly.

Cleaner cuts speed up the entire production process
For Lisnave, improving pipe production was about more than increasing cutting speed. The company needed a solution that could deliver better quality while reducing the work required after cutting. After researching different suppliers, the team visited HGG and saw the technology in operation.
Hugo Simões, Head of Production: “When I went to the headquarters of HGG and saw a similar machine working, that’s when we made the final decision: it has to be this one.”
Since integrating the ProCutter 900 into production, the benefits have continued beyond the cutting process. Pipe Shop Coordinator Ivo Nunes: “We have better quality and are much faster, with less cleaning time required. Because the machine produces cleaner, more precise cuts, it makes assembling the pieces much easier.”
With less preparation required between cutting and assembly, Lisnave can move its pipe spools through production faster while maintaining the quality its customers expect.
Faster spool manufacturing for a wide range of ship systems
The ProCutter 900 now supports Lisnave in manufacturing piping for numerous applications on board the vessels it repairs. This includes pipes and flanges for cargo lines, sanitary systems, fire lines, oxygen lines and other piping systems, as well as components required during storage tank refurbishment.
The machine has also been well received on the shop floor. Pipe fitter and operator Celso Varela: “I’ve been working with this machine for a year now. I like it a lot and the software is impressive. It’s fast and I love it. The machine is very intuitive.”
By combining faster production with cleaner cuts and easier assembly, the ProCutter 900 has become an integral part of Lisnave’s pipe shop. For Hugo Simões, the investment is also about strengthening the department for the years ahead: “I know that we made the best decision, and this will make an impact for us, especially in the piping department, for the future.”
