Classification and technical assurance with controlled authority.
HCS combines classification, technical survey, plan appraisal, statutory support and specialized marine review within a documented framework of competence, evidence, technical review and traceable decision-making.
Evidence first. Review second. Decision controlled.
HCS technical work is based on the applicable HCS Rules, statutory instruments, Flag instructions, approved plans and objective survey evidence. Attendance by a surveyor does not, by itself, constitute a certification decision. Formal class and statutory actions remain subject to the required technical review and authorization process.
