Oil Water Separators - Auxiliary Machinery and Engine Room

Marine oily water separators treat machinery-space bilge water by removing oil before discharge or retention. Approved systems use separation stages and a 15 ppm bilge alarm with automatic stopping or recirculation to comply with MARPOL Annex I.

ProShipWorks provides end-to-end support to source and supply Oil Water Separators for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval

Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.

Applicable Standards & Certification Marine oily water separator systems are governed by MARPOL Annex I and IMO Resolution MEPC.107(49). The separator, 15 ppm bilge alarm, automatic stopping device and associated records must meet flag-state type-approval and installation requirements.
Class Approval Type-approved configurations may be accepted or certified by DNV, ABS, Lloyd's Register, Bureau Veritas and ClassNK. Approval is model-, configuration- and flag-state-specific; the applicable type-approval certificate must be verified before purchase or installation.

Installation, Maintenance & Safety Information

Installation Notes Install according to the approved piping diagram with dedicated bilge feed, oil/sludge outlet, sampling point, recirculation or stopping arrangement and overboard valve control. Prevent bypasses, provide suitable strainers and verify alarm interlocks during commissioning.
Maintenance Tips Inspect and clean strainers, coalescers, filters, adsorption media and separator internals at manufacturer-specified intervals. Calibrate and function-test the 15 ppm bilge alarm, automatic stopping device, valves and sampling lines, and keep maintenance records.
Safety Notes Isolate electrical power and depressurize the system before maintenance. Treat bilge residues and used filters as oily waste, use appropriate PPE, and never bypass the oil-content monitor, automatic stopping device or approved piping arrangement.
