Vessel Retrofits & Conversions
Complete Retrofit Delivery from Survey to Commissioning
ATOZ Group manages vessel retrofit and conversion projects involving machinery, electrical systems, piping, ventilation, automation and structural modifications. Support can cover an individual equipment replacement or a complex upgrade involving several technical disciplines.
Each project begins with a review of the existing vessel arrangement, equipment specifications, available documentation and operational requirements. Where additional information is needed, our team can carry out onboard surveys and 3D scanning to collect accurate measurements and identify installation constraints.
Based on the confirmed scope, ATOZ coordinates engineering, material and equipment sourcing, workshop prefabrication and the preparation of components for installation. Work can then be carried out onboard at the vessel’s location, during a scheduled port call or as part of a wider dry-dock program.
Following installation, our specialists support system testing, commissioning, technical documentation and project handover. Coordinating these stages through one team helps reduce gaps between design, production and onboard execution.
