The International Association of Classification Societies (IACS) continues to modernize ship classification processes. One of the most significant recent developments is the expanded use of remote surveys. This approach allows class surveyors to carry out many inspection activities without physically boarding the vessel.

Remote surveys have proven especially valuable during periods of restricted travel, port access limitations, and urgent operational needs. IACS member societies have now finalized unified procedures that make remote inspections more consistent, reliable, and widely accepted by flag states and port authorities.

What Types of Surveys Can Be Performed Remotely?

According to the latest IACS guidance, the following survey types are suitable for remote execution when specific conditions are met:

1. Annual surveys (hull, machinery, and equipment)
2. Intermediate surveys
3. Bottom surveys (in-water inspections using ROV or divers with live video feed)
4. Tailshaft and propeller surveys
5. Boiler and pressure vessel inspections
6. Repairs following minor damage
7. Postponement assessments for certain periodical surveys

Remote surveys are not permitted for major special surveys, initial surveys, or situations requiring close-up physical examination of critical structural elements unless exceptional justification is provided and approved.

Key Requirements for Successful Remote Surveys

For a remote survey to be accepted, several strict conditions must be fulfilled:

1. High-quality, stable live video streaming with good resolution and real-time communication
2. Qualified ship’s crew or third-party service provider acting as the surveyor’s “eyes and hands”
3. Clear identification of the surveyor, ship’s staff, and all equipment involved
4. Secure, recorded, and timestamped video material for future reference
5. Proper lighting, access to all required areas, and calibrated measuring tools when needed
6. Advance approval from the classification society and, when required, the flag administration

These measures ensure that the quality and thoroughness of the survey remain equivalent to an onboard inspection.

Benefits for Seafarers and Ship Operators

Remote surveys bring several practical advantages to crews and companies:

1. Reduced waiting time in ports for surveyor attendance
2. Lower exposure to health risks during pandemics or disease outbreaks
3. Decreased travel costs and carbon footprint
4. Faster return to commercial operations after repairs or inspections
5. Greater flexibility in scheduling surveys around cargo operations

At the same time, seafarers remain responsible for preparing the vessel, providing safe access, and assisting during the live inspection. Good preparation and clear communication with the remote surveyor remain essential for a smooth process.

Looking Ahead

IACS emphasizes that remote surveys are not intended to fully replace traditional onboard inspections. They serve as a complementary tool, especially in well-defined, low-risk scenarios. The association continues to monitor the effectiveness of these procedures and update them based on operational experience.

As digital tools and connectivity improve, remote and hybrid survey methods are expected to become a standard part of modern ship classification.
