ALMACO Group Successfully Delivers Modular Cabins for Spirit of Tasmania IV and V 


Posted on December 2, 2025

ALMACO is proud to announce the successful delivery of modular cabins for TT-Lines Spirit of Tasmania IV and Spirit of Tasmania V. The deliveries took place in two phases, with the first vessel modular cabins delivered in 2024 and the cabins for the second vessel in 2025. The construction of the vessels took place at Rauma Marine Constructions yard in Finland. 

ALMACO’s scope included the delivery of 764 cabins and 382 per vessel. 347 cabins were delivered as modular units and fabricated off site. Materials were delivered for the remaining 35 cabins that were constructed on board. The 382 cabins per vessel consisted of 301 passenger cabins and 81 crew cabins. 

The modular cabins were assembled in ALMACO’s Mobile Cabin Factory, a popup production line set up off site in a warehouse between Rauma and Turku. This approach enabled high-quality cabin production close to the shipyard and increased efficiency by having simultaneous work carried out in two locations.  

Once completed, the fully finished cabins were transported to the Rauma Shipyard, lifted onboard, and seamlessly integrated into the vessels. The only post-delivery installation required was the connection of electricity, ventilation, and piping systems. This type of offsite modular cabin production led to reduced installation time at this phase of the project. 

Niko Vainionpää, Project Manager at ALMACO, comments on the project: “We are honored to have contributed to these vessels and proud of the teamwork that made it possible. We are also happy that our first project together with Rauma Marine Constructions was a success.” 

The Spirit of Tasmania IV and V are powered by LNG (Liquified Natural Gas), underscoring TT-Line’s commitment to sustainability and innovation in maritime transport. The vessels are operating between Australia and Tasmania.
