CARGO REQUIRING A SPECIFIC METHOD
Do not infer a generic water wash or chemical recipe; verify the exact product and approved method.
01BEFORE LOADING
Select the correct with/without-binder schedule.
Open the checks →
02AFTER DISCHARGE
Do not assume an apparently empty hold is gas-safe.
Open cleaning checks →
03VISUAL INSPECTION
Explore hatch undersides, framing, tank top and bilge checks on the numbered map.
Go to the map →Cargo images are illustrative. Shared hold and coating photographs introduce inspection topics; they do not show carriage of the selected cargo or completion of an operation. They are not a before/after comparison.

CARGO TRANSITION WORK FILE
Existing checks from the selected profiles are assembled here; this is not a validated transition-specific chemical recipe or carriage-compatibility decision. Entered information is not submitted or stored on the server and is lost on leaving the page.

VISUAL FIELD GUIDE
Open a numbered heading to inspect the highlighted area and its check note together. The drawing does not authorise access or entry.
Check deposits that may fall back from hatch undersides and channels. Keep drainage clear.
Record: Hatch underside / channel photographDo not infer clean upper recesses and blind faces from a clean tank top.
Record: Upper-surface observation recordCheck front and back faces separately; record loose deposits, scale and flaking paint.
Record: Blind-face inspectionCheck behind rungs and supports for residue; do not use damaged access fittings.
Record: Access defect / work orderCheck plate edges and cover recesses for solids, water and impact damage.
Record: Closing tank-top photographInspect wells and protection; do not leave fine sludge within fixed piping.
Record: Well / strainer checkInclude surfaces behind pipes and guard recesses in inspection coverage.
Record: Behind-pipe / guard recordAssess an approved small representative patch; do not automatically extrapolate to the whole hold.
Record: Before/after and coating findingsSIX-STAGE WORK PLAN
This sequence requires product/specialist instructions. The flow below is for planning and verification only; no generic wet-cleaning procedure is provided.
01Record: Cargo declaration + written acceptance criteria
Stop / reassess: Do not select a method with unknown residue or standard.
Write down previous residue, intended cargo and required standard. Plan water, equipment, time and waste arrangements accordingly.
Reference document ↗
02Record: Permit / measurements / equipment records
Stop / reassess: Do not enter if atmosphere, access or rescue conditions are unmet.
Under the SMS, verify risk assessment, permit, isolation, atmosphere testing, communications and rescue.
Reference document ↗
03Record: Residue type + collection / disposal route
Stop / reassess: Do not start generic water/chemical cleaning on unknown or reactive residue.
Distinguish loose solids, oily film, adherent deposits and reactive material. Establish a suitable collection method.
Reference document ↗
04Record: Product / batch + dilution + contact time
Stop / reassess: Stop for coating softening, colour transfer or an unexpected reaction.
Match exact-product SDS/PDS with coating and following-cargo requirements. Record an approved patch trial and result.
Reference document ↗
05Record: Water source + rinse / drying observations
Stop / reassess: Do not close the stage under time pressure if product/cargo conditions are unmet.
Wash/rinse only when permitted by the approved method. Check water used, remaining detergent/salt and dryness against the following cargo.
Reference document ↗
06Record: Before/after photographs + open items + acceptance record
Stop / reassess: Plan correction and reinspection if residue, odour, moisture or defects remain.
Reinspect the eight areas; retain photographs, open defects and required survey findings. Work completion is not cargo acceptance.

Determine the cargo’s HME status and assess cleaning agents, discharge location and applicable MARPOL Annex V/local requirements. A supplier’s non-HME statement for a cleaner does not itself authorise discharge of the complete wash-water mixture. Arrange reception facilities when required and retain the applicable records.

Click a product name to open the manufacturer’s official SDS access page in a new tab. Search the exact product name and select the relevant country/jurisdiction and language where available. Match the current full SDS to the product on board. A product data sheet or Mini SDS does not replace the full SDS.
Review these products as alternatives; do not mix them. Manufacturer summaries below require the same product/formulation, compatible coating and company-approved work plan. Current full SDS/PDS takes precedence; a summary alone is not application approval. Reviewed 17 October 2026.
No previous cargo selected: preloading residue-cleaning products cannot yet be identified. Any documents below concern the intended cargo’s own preparation/after-discharge stages.
No ready-made chemical application package is supplied for this sequence. Exact residue, cargo, coating and reactivity information requires a company/manufacturer/specialist method.
