Differences between SAMS, NAMS and IIMS: What Certification Demands Case

1. Why does Perito Certification matter?

In the world of naval expertise, there is an abysmal difference between a “marine surveyor” (a generic title that anyone can self-open) and a “accredited marine surveyor” (professional certified by an internationally recognized organization that has demonstrated technical competence, professional ethics and documented experience).

This distinction is not merely academic. It has critical practical implications:

• Judicial validity: Arbitral tribunals (LMAA, SMA, ICC) give much more weight to certified expert reports.
• Acceptance by insurers: The main maritime insurers (Lloyd’s of London, Chubb, AXA XL) require certified experts to validate claims.
• Bank recognition: Banks that finance yachts and commercial ships only accept credits.
• Professional responsibility: Certifying organizations require professional civil liability insurance and strict codes of ethics.

2. SAMS (Society of Accredited Marine Surveyors)

Founded in 1962 and based in Florida (USA), SAMS is considered the most prestigious and rigorous certification organization in the world in naval expertise. Its accreditation process is the most demanding and its recognition is global.

2.1. Categories of Accreditation SAMS

SAMS offers three levels of accreditation, each with specific requirements:

• Marine Surveyor (MS): Input level. It requires demonstration of minimal experience (5 years), professional references, approval of technical and ethical examinations, and presentation of sample reports for peer review.
• Senior Marine Surveyor (SMS): Advanced level. It requires 10+ years of experience, demonstrated leadership in the sector, publication of technical articles or participation in society committees, and revaluation every 3 years.
• Certified Marine Surveyor (CMS): The highest level. It requires 15+ years of experience, exceptional recognition in the sector, and a comprehensive evaluation process that includes audit of reports and interviews with the accreditation committee.

2.2. Areas of Specialization SAMS

SAMS experts specialize in specific areas:

• Yachts & Small Craft: Recreation yachts, sailboats, motor boats up to 300 GT.

• Marine Machinery: Engines, propulsion systems, auxiliary machinery.

2.3. Where SAMS Certification is required

SAMS is particularly valued and frequently demanded in:

• United States: It is the de facto standard in American maritime litigation (SMA, federal courts).

• American insurers: Lloyd’s of London (USA), Chubb, Travelers demand SAMS experts for claims over $500,000.

3. NAMS (National Association of Marine Surveyors)

• Latin America: Recognized in countries with strong American influence (Mexico, Panama, Colombia).
