• Abstract:

  This article analyzes the role of technical supervision in Brazilian shipbuilding and repair, discussing its importance for regulatory compliance, the structural integrity of hulls and machinery systems, and accident prevention in high-risk environments. Based on a qualitative literature review covering national and international academic literature, standards such as NR-34, NORMAM, and IMO conventions, technical documents, dissertations, and institutional reports, the study identifies recurring weaknesses in shipyards, such as informal processes, low standardization, training gaps, and difficulties in integrating engineering, production, safety, and quality. Based on this evidence, a framework of good practices in technical supervision is proposed, consisting of six pillars—standardization and traceability, quality control and metrology, structural integrity and NDT, machinery and commissioning, operational safety, and technical governance—aimed at reducing rework, mitigating critical risks, and increasing the sector's competitiveness. The article also discusses how digitization, Naval Industry 4.0, and technologies such as sensors, electronic traceability, and digital twins expand the scope and complexity of supervision, requiring more structured, risk-based models supported by training and institutional strengthening policies.
