Machinery Equipment Spares (IMPA 87)
IMPA section 87 is the broad auxiliary machinery category that captures engine and separator spares and the pollution-control equipment that keeps a ship MARPOL-compliant. It is where buyers find oily-water-separator and 15 ppm bilge-alarm spares, auxiliary engine components and the consumables that support the main and auxiliary machinery indexed under the OEM hubs. Because this section spans safety- and pollution-relevant equipment, sourcing here ties closely to compliance: an oily-water separator and its alarm must hold the right approvals, and engine spares carry material traceability. This hub connects the auxiliary machinery sub-components to the OEM series where the exact parts live, and to the compliance guidance that governs the pollution-control equipment in particular.
Pollution-control equipment
Oily-water separators and their 15 ppm bilge alarms are the compliance-critical items in this section, requiring USCG approval and MARPOL Annex I conformity for overboard discharge.
Regulatory overview
Oily-water separators and 15 ppm bilge alarms require USCG approval (46 CFR 162.050) and MARPOL Annex I compliance for bilge discharge limited to 15 ppm. Engine spares are internal components carrying EN 10204 material traceability.
