Ship Docking Paint Requirement Calculator
Terima kasih untuk Muhammad Wiranto atas partisipasi dalam membuat fitur ini.
Typical DFT: 50-300µm | Typical VS: 50-85% | Typical Coats: 1-3 per layer
Topside Area
Underwater Area
Formula Used:
Liters = (Surface Area × DFT × Coats) / (VS% × 10) × (1 + Risk Factor)
This is the standard industry formula used by major paint manufacturers (Jotun, International Paint, Hempel).
Underwater Area Factor Guidelines:
- 1.5: Slender vessels (Container ships, Fast ferries)
- 1.6: Medium fullness (Bulk carriers, General cargo) - Default
- 1.7: Full-form vessels (Tankers, VLCCs)
- 1.8-2.0: Very full forms (Some specialized vessels)
Risk Factor Guidelines:
- 10-15%: Good surface condition, experienced crew, minimal repairs
- 15-20%: Normal condition, standard repairs - Recommended Default
- 20-30%: Poor surface condition, extensive repairs, difficult access areas
- 30%+: Severe corrosion, major structural repairs, complex geometry
Important Notes:
- Rounding: Number of pails is always rounded up to the nearest whole number.
- Pail Sizes: Calculations shown for both 18L and 20L pails. Cost estimation uses 20L pail price.
- Bulk Packaging: For high-volume paints, suppliers may offer larger drums (200L, 1000L). Convert total liters accordingly.
- Safety Stock: Consider adding 5-10% extra pails for unforeseen circumstances or touch-ups.
- Surface Preparation: Calculations assume proper surface preparation. Poor preparation may increase consumption.
- Application Method: Spray application typically uses more paint than roller/brush. Adjust risk factor accordingly.
Disclaimer: This calculator provides an estimate based on standard formulas. Always consult with paint manufacturers, yard specifications, and experienced personnel for precise planning and costing. Actual consumption may vary based on surface condition, application method, weather conditions, and crew experience.

About Ship Docking Paint Calculator
What is a Ship Paint Calculator?
A ship docking paint calculator is a professional tool used by marine engineers, ship owners, and shipyard managers to accurately estimate the amount of marine paint required during vessel dry docking operations. This calculator considers vessel dimensions (LOA, beam, draft), paint specifications (DFT, volume solids), and risk factors to provide precise paint quantity and cost estimates.
How to Use This Marine Paint Estimation Tool
- Enter Vessel Particulars: Input your ship's Length Overall (LOA), Beam, and Draft in meters.
- Set Underwater Area Factor: Choose 1.5 for container ships, 1.6 for bulk carriers, or 1.7 for tankers.
- Configure Risk Factor: Set 10-15% for good conditions, 15-20% for normal, or 20-30% for poor surface conditions.
- Input Paint Specifications: Enter DFT (Dry Film Thickness), VS (Volume Solids %), and number of coats for each paint layer.
- Set Paint Prices: Input the price per 20L pail in your preferred currency (USD or IDR).
- Review Results: Get instant calculations for liters needed, number of pails, and total estimated costs.
- Export Quotation: Generate a professional PDF quotation for your client or procurement team.
Marine Paint Types Supported
- Topside Paints: Epoxy zinc-rich primer, epoxy mastic intermediate coat, polyurethane topcoat
- Underwater Paints: Epoxy glass flake barrier coat, self-polishing copolymer anti-fouling paint
- Special Coatings: High-build epoxy, glass flake epoxy, silicone-based anti-fouling
Vessel Types Supported
This calculator works for all commercial vessel types including bulk carriers, oil tankers, chemical tankers, container ships, general cargo vessels, offshore support vessels, and more. Each vessel type has different hull forms, which is why the underwater area factor is adjustable.

- ✓ Professional PDF Export: Generate quotations for clients with customizable templates
- ✓ Risk Factor Included: Accounts for wastage, spillage, and difficult access areas
- ✓ Multiple Paint Systems: Support for complete paint systems from primer to topcoat
- ✓ Free to Use: No registration or payment required
Understanding Paint Calculation Terms
- DFT (Dry Film Thickness):
- The thickness of the paint film after drying, measured in microns (µm). Typical range: 50-300µm depending on paint type.
- VS (Volume Solids):
- The percentage of paint that remains after solvents evaporate. Higher VS means less paint needed. Typical range: 50-85%.
- Risk Factor:
- Additional percentage added to account for wastage, spillage, surface irregularities, and difficult-to-reach areas.
- Underwater Area Factor:
- Multiplier that accounts for the actual underwater hull shape. Varies by vessel type from 1.5 (slender) to 1.7 (full-form).
Best Practices for Ship Paint Estimation
- Always verify vessel dimensions from official drawings or survey reports
- Consult paint manufacturer's Product Data Sheets (PDS) for accurate DFT and VS values
- Consider surface condition when setting risk factor - poor surfaces need higher percentages
- Add 5-10% safety stock for touch-ups and unforeseen requirements
- Verify paint prices with local suppliers as they vary by region and quantity
- Consider application method - spray typically uses more paint than roller/brush
