Solution

A disciplined end-to-end sequence was applied, combining mechanical cleaning, controlled washing chemistry, high-pressure cleaning, surface preparation, and coating works—aligned with shipboard safety controls and common industry expectations for cargo integrity and P&I risk management:

1) Pre-work condition survey & work planning

• Hold-by-hold condition mapping (residue types, staining, coating integrity, rust scale, bilge condition)

• Work sequencing by zones: tank top → lower hopper/side areas → upper regions/frames → bilges → hatch interfaces

• Permit controls for enclosed spaces, ventilation strategy, and segregation of waste streams

2) Bulk residue removal & seawater pre-wash

• Sweeping/collection to remove loose residues prior to washing

• Seawater pre-wash to break down adhered deposits and reduce surface loading before high-pressure stages

• Dedicated attention to “carry-over points”: frame toes, ladder landings, drain edges, and corner transitions

3) Chemical wash (cargo-contamination control)

• Controlled application of cargo-residue cleaning chemistry (owner-approved) to lift staining and embedded contamination

• Rinse discipline to avoid re-deposition on frames and upper structures

• Focus on sugar-critical contamination points: streaking paths, shadow zones behind structural members, and bilge-adjacent surfaces

4) Hydro-jetting / high-pressure cleaning

• High-pressure washing/hydro-jetting applied where required to remove persistent residues and prepare surfaces for coating works

• Structured progression to avoid cross-contamination: “clean-to-dirty” zoning, top-down rinse logic, and re-check of frame pockets

5) Bilge detailing & drainage readiness

• Bilge wells and drain channels cleaned to eliminate residual contamination risk

• Collection/segregation of residues and wash water management per applicable ship/port requirements and environmental controls (as applicable to the operation)

6) Surface preparation & cargo hold painting

• Spot preparation where needed (scale/rust removal and edge conditioning)

• Coating application per owner/technical specification (touch-up/renewal)

• Stripe/critical-area attention: frame toes, edges, bracket corners, weld transitions, and abrasion zones

• Drying control using ventilation and operational discipline for coating cure windows

7) Final acceptance checks (“hospital-standard” finish)

• Final wipe-down/verification for powdering, loose particles, staining traces, and debris

• Visual quality checks across frames, tank top, ladders, and hatch interfaces

• Holds delivered in an inspection-ready condition for loading sequence alignment
