Our Standard: Commitment & Quality

Every intervention adheres to defined technical procedures, prioritizing reliability, energy efficiency, and safety.

STS Yacht Workshop & Technical Facilities

The Methodology

ONE STANDARD. FOUR PHASES. ONE RELIABLE RESULT.Every project follows a defined methodology from initial diagnostics to commissioning, coordinating people, resources, and procedures to ensure onboard safety, efficiency, and reliability.

Phase 01

Technical Diagnostics

We inspect the system, identify the root cause of the issue, and evaluate overall equipment condition before intervening.

Phase 02

Planning & Resources

We define the technical procedure, delivery timelines, required parts, and safety protocols before starting work.

Phase 03

Controlled Technical Execution

Our certified technicians carry out the intervention following defined procedures, marine regulations, and technical debriefings with onboard engineers and captains.

Phase 04

Validation & Handover

We conduct functional testing, verify operating parameters, and document the intervention. Handover is completed only after verifying flawless system performance with client sign-off, leaving the vessel ready to return to service.

"We had a hydraulic breakdown on the autopilot and contacted the technician by message and phone. He arrived as soon as we docked at Badalona marina, around 17:30. He returned the next morning with the necessary parts and oil to repair and bleed the system. We are delighted with the speed of response, diagnosis, and technician efficiency. Thank you so much!"
