MaxiDive successfully completed a rudder clearance measurement Thailand project at Laem Chabang Port, Thailand. The operation was performed to record underwater rudder clearance measurements for technical review and vessel maintenance documentation.
The work was carried out while the vessel remained afloat, using commercial diving equipment, CCTV recording, and steel measurement tools provided by the vessel. The underwater measurements were taken at six marked positions between the rudder upper plate and lower plate.
Rudder Clearance Measurement Thailand for Technical Verification
Rudder clearance measurement Thailand is an important underwater inspection service used to verify rudder condition, alignment, and clearance values without requiring dry dock attendance.
For this project, MaxiDive’s commercial diving team conducted CCTV-recorded rudder clearance measurements at Laem Chabang Port. The vessel remained afloat during the operation, helping reduce operational disruption and avoid unnecessary downtime.
The inspection was performed under calm sea conditions with underwater visibility of approximately 1.5 meters.
Project Scope – Rudder Clearance Measurement Thailand
The scope of this rudder clearance measurement Thailand operation included:
Commercial diving team mobilization
Coordination with the vessel representative and attending surveyor
Underwater access to the rudder area
CCTV-recorded inspection
Measurement of rudder clearance at six marked positions
Starboard side measurements
Port side measurements
Use of vessel-provided steel ruler
Documentation for class and technical review
The operation was completed using a Kirby Morgan KMB28C helmet and VIC CCTV system.
Rudder Clearance Measurement Results
Divers successfully conducted CCTV-recorded rudder clearance measurements between the rudder upper plate and lower plate.
The recorded measurements were:
Starboard side:
AFT: 32 mm
MID: 59 mm
FWD: 73 mm
Port side:
AFT: 32 mm
MID: 52 mm
FWD: 74 mm
These measurements provided the vessel’s technical team and attending surveyor with clear underwater documentation of rudder clearance condition.
Why Rudder Clearance Measurement Is Important
Rudder clearance measurement is an essential part of vessel condition assessment and maintenance planning. Excessive or uneven clearance may indicate wear, alignment issues, or the need for further technical evaluation.
Professional rudder clearance measurement Thailand services help shipowners and managers:
Verify rudder clearance condition
Support class and technical review
Reduce dry dock dependency
Plan maintenance more accurately
Document underwater findings
Assess port and starboard rudder clearance values
Maintain vessel operational reliability
For vessels calling at Laem Chabang Port, underwater rudder measurement provides an efficient way to collect required technical data while the vessel remains in the water.
CCTV-Recorded Underwater Rudder Inspection
For this project, MaxiDive performed the rudder clearance inspection with CCTV recording. This allowed the measurement process to be visually documented and reviewed by the vessel’s technical team.
CCTV documentation is valuable because it provides:
Visual confirmation of the measurement position
Evidence of the measuring method
Support for class review
Clear inspection records
Reduced ambiguity in technical reporting
The use of underwater video recording helps improve transparency and supports reliable vessel maintenance decision-making.
