Hull Survey Assistant
Generate vessel hull surveys with defect classification and repair prioritization
What You Can Do
Generate professional hull survey reports that systematically document and analyze vessel hull conditions. You provide vessel specifications, defect observations, and damage locations—this skill produces structured survey documents with defect classification by severity, detailed damage narratives for insurance and regulatory purposes, repair recommendations ranked by urgency and structural impact, and compliance-ready documentation for classification societies.
Features
Automatically categorizes hull damage by type (corrosion, pitting, cracking, deformation) and severity level (minor, moderate, critical) based on structural impact and measured dimensions.
Produces professional, detailed damage descriptions suitable for insurance claims and classification society submissions, including precise measurements, location references, and technical condition analysis.
Ranks defects and repairs by urgency based on structural risk, seaworthiness impact, and regulatory compliance, generating actionable repair schedules with time windows.
Formats complete survey documentation including executive summary, vessel details, defect tables with photos, location mapping, technical findings, and professional recommendations.
Evaluates overall hull integrity, analyzes corrosion patterns and thickness loss, and assesses impact on vessel classification and long-term structural soundness.
Cross-references findings against ABS, DNV, Lloyd's Register, and other classification society standards to confirm recommendations meet regulatory requirements.
Provides repair cost ranges and estimated downtime by defect severity, supporting fleet maintenance budgeting and operational planning.
Organizes defects by vessel zone (bow, midship, stern, engine room) and structural section for easy tracking, follow-up, and coordination during repairs.
Example Output
Example 1: Defect Summary Table
| Location | Type | Severity | Size | Thickness Loss | Recommendation |
|---|---|---|---|---|---|
| Starboard Hull, Frame 45 | Pitting Corrosion | Moderate | 120×80mm | 2.5mm | Local blast & epoxy coat |
| Port Bilge Strake | Cracking | Critical | 340mm linear | N/A | Weld repair + X-ray |
| Rudder Trunk Seal | Seawater Seepage | Minor | N/A | N/A | Re-pack gland & sealant |
Example 2: Professional Damage Narrative
Starboard hull plating exhibits active general corrosion concentrated along the waterline at Frame 45. Pitting depth measured at 3.2mm across a localized 120mm × 80mm area. No through-thickness perforation detected. Material loss estimated at 8% of local section modulus. Recommendation: Shot blast to bare metal, perform ultrasonic thickness survey of surrounding area, apply two-part epoxy protective coating.
Example 3: Repair Priority Ranking
URGENT — Schedule within 30 days:
- Port bilge cracking (structural risk, class defect)
- Starboard engine room penetration (active water ingress)
HIGH — Schedule within 90 days:
- Pitting corrosion at waterline (active corrosion progression)
ROUTINE — Next planned drydock:
- General topside rust (cosmetic, low structural impact)
