Pre-Dock Steel Condition Surveys
Know your vessel's true steel condition before entering dry dock. Avoid unexpected repairs, delays, and budget overruns.
NDTest pre-dock surveys provide comprehensive steel condition assessment using ultrasonic thickness measurements (UTM), close-up inspections, rope access techniques, and detailed photo documentation. Define your renewal scope confidently and negotiate with shipyards using independent inspection data.

What's Included in a Pre-Dock Survey
A comprehensive NDTest pre-dock survey combines multiple inspection methods and detailed documentation to give you complete visibility into your vessel's steel condition before entering dry dock.
Ultrasonic Thickness Measurements (UTM)
Precise measurement of hull steel thickness at critical locations to detect corrosion, wear, and structural degradation. Measurements are recorded and organized by compartment and location for detailed analysis.
Close-Up Visual Inspections
Detailed visual assessment of suspect areas, corrosion hotspots, and structural concerns. Inspectors examine paint condition, surface defects, and areas requiring remediation or repair.
Rope Access Assessment
IRATA-certified technicians access hard-to-reach compartments—cargo holds, ballast tanks, under-deck spaces—to inspect areas inaccessible by conventional means and assess structural condition.
Photographic Documentation
High-quality photographs of key areas, identified defects, corrosion patterns, and structural concerns. Photos are annotated and organized to support findings and recommendations.
Corrosion & Wear Analysis
Professional assessment of corrosion patterns, remaining service life of steel structures, and areas of accelerated wear. Analysis supports planning for steel renewal and repair priorities.
Steel Renewal Scope Estimation
Quantified estimate of the area and volume of steel requiring renewal or repair, including weight calculations. This data supports accurate budgeting and shipyard negotiations.
Structural Sketches & Diagrams
Professional drawings and diagrams showing affected areas, repair scope, and structural details. Sketches clearly mark locations and extent of required work for shipyard planning.
Written Recommendations
Professional recommendations for repairs, steel renewal priorities, and remediation strategies. Recommendations are based on structural assessment and class society compliance requirements.
Why This Comprehensive Approach Matters
Plan with Confidence
Know exactly what repairs are needed before entering dry dock—no surprises or scope creep.
Control Your Budget
Accurate repair scope and weight calculations support precise budgeting and cost control.
Strengthen Negotiations
Independent inspection data gives you credible documentation for discussions with shipyards.
Ensure Class Compliance
Reports meet DNV, RINA, and ClassNK standards—accepted by classification societies.
The Pre-Dock Survey Process
We walk you through every step of the pre-dock inspection journey—from initial consultation to final report delivery. Our transparent, professional process reduces uncertainty and gives you the clarity needed to plan confidently before entering dry dock.
Initial Consultation
We begin by understanding your vessel, inspection requirements, and business timeline. During this consultation, we discuss:
- • Vessel specifications and construction details
- • Areas of concern or known issues
- • Planned dry dock date and timeline
- • Budget parameters and scope limitations
Survey Planning & Coordination
We develop a customized inspection plan tailored to your vessel and objectives. This phase includes:
- • Defining critical inspection areas (holds, ballast tanks, hull zones)
- • Coordinating with ship management and crew for access
- • Scheduling inspection dates and mobilization logistics
- • Confirming equipment, personnel, and safety protocols
On-Deck Inspection & Data Collection
Our certified NDT specialists conduct comprehensive on-site inspections using multiple methods:
- • Ultrasonic Thickness Measurements (UTM) — precise hull steel thickness assessment
- • Close-Up Visual Inspections — detailed examination of suspect areas
- • Rope Access Inspections — safe access to hard-to-reach compartments
- • Photo Documentation — high-quality evidence of condition and findings
Data Analysis & Assessment
Back in our office, our engineering team conducts detailed analysis of all collected data:
- • Corrosion pattern analysis and wear assessment
- • Steel renewal scope estimation with weight calculations
- • Classification society requirement cross-reference
- • Repair cost and timeline preliminary planning
Comprehensive Report Preparation
We prepare a detailed, professional report that becomes your primary tool for planning and negotiation:
- • Thickness measurement tables organized by compartment and location
- • Corrosion analysis with structural impact assessment
- • Steel repair estimation with weight and material specifications
- • Structural sketches and repair diagrams
- • Complete photo documentation with annotated findings
- • Executive summary with key recommendations
All reports are prepared to classification society standards and accepted by DNV, RINA, and ClassNK.
Report Delivery & Discussion
We deliver the final report and discuss findings with you directly:
- • Presentation of key findings and renewal scope
- • Discussion of repair priorities and budget implications
- • Support for shipyard negotiations using independent data
- • Clarification of technical details and recommendations
Transparency & Communication Throughout
Every step of our pre-dock survey process is designed with transparency and professional communication in mind. We keep you informed at each stage, answer your questions promptly, and ensure you have the independent, detailed information you need to make confident decisions before entering dry dock.
By the time your vessel reaches the shipyard, you'll have a comprehensive understanding of steel condition, defined renewal scope, and realistic cost projections—eliminating surprises and giving you negotiating power with your repair facility.
