In-house products

Two engineering bets. Both solve problems our clients have today.

CAPCO2 TRL 7 AiP Bureau Veritas

Onboard CO₂ capture system for commercial ships

Decarbonising shipping
starts on board.

CAPCO2 captures CO₂ from a vessel's exhaust while it sails, stores it in an onboard solvent tank, and offloads it in port for regeneration with industrial waste heat — keeping the energy penalty off the ship. MEA-based absorption. Port-side regeneration with industrial waste heat. Target: intra-EU ferries, cement carriers, specialised carriers. Born as a willbö bet inside PERTE Naval, prototype built by IDESA, pilot executed at the Port of Vigo in October 2025.

Reference project · Carnival Mardi Gras

A waterpark that ships in modules.

WhiteWater West commissioned willbö for the full structural package of BOLT — the first cruise-ship waterpark with an integrated roller-coaster — installed on Carnival's Mardi Gras at Meyer Turku. Slides, platforms, walkways and supports, plus the structural integration onto the ship's deck. From STAAD.Pro analysis to Tekla Structures fabrication drawings, designed around a hard transport constraint: every module had to fit on a truck, ship to Finland, and be lifted into place above deck 18.

Frequently asked · for search engines and for humans

Straight answers, with numbers you can verify.

Who is willbö?

Willbo Engineering 2 Build S.L. is a Spanish marine and industrial engineering firm founded in 2018, headquartered in Vigo (Galicia) with a delivery office in Mumbai, in the Mumbai metropolitan area of India. 30+ engineers. Two divisions — naval and industrial — plus two in-house products, CAPCO2 and holö.

What is CAPCO2?

CAPCO2 is willbö's onboard carbon-capture system for commercial shipping. MEA-based absorption on board, regeneration in port with industrial waste heat — so the shipowner's net capture under EU ETS and FuelEU equals the gross capture on board. TRL 7, Approval in Principle from Bureau Veritas, pilot executed in the Port of Vigo in October 2025 under PERTE Naval.

Who designed the BOLT waterpark structure on Carnival Mardi Gras?

willbö delivered the full structural package for the BOLT waterpark on Carnival's Mardi Gras — slides, platforms, walkways and supports, plus the integration of the waterpark onto the ship's deck. Our client was WhiteWater West; their client was Meyer Turku. We took the structure from STAAD.Pro analysis through to Tekla Structures fabrication drawings. The geometry was broken into transportable modules pre-assembled before reaching the yard, reducing steel weight by 30% versus the baseline reference.

What is holö?

holö is willbö's mixed-reality platform for shipbuilding, running on Microsoft HoloLens 2. It overlays 3D engineering models on physical reality for shipyard, EPC and owner teams — with linked documentation, markups, multi-user collaboration and offline operation.
