OILY WATER SEPARATOR (OWS) DESIGN DRIVERS
• Certification
• Price
• Performance
• Ease Of Operation
• Reliability
• Maintainability
• Cost Of Operation

FACTORS INFLUENCING PERCEIVED DESIGN DRIVER VALUE
• Business Type– Shipyard, Operator, Owner
• Environmental Sensitivity• Technical Staffing• Crew Capability and Size• Voyage Length and Location• Maintenance Policies• Vessel Type• Ship Design
COFFIN WORLD WATER SYSTEMS
EXAMPLES OF OWS TECHNOLGIES IN USE
• Separation Technologies– Membranes– Coalescing– Centrifuges– Adsorption– Flocculation
COFFIN WORLD WATER SYSTEMS
Standards
• IMO MEPC 107(49) “Revised Guidelines and Specifications for Pollution Prevention Equipment for Machinery Space Bilges of Ships”
• IMO MEPC.1 Circ 642 “2008 Revised Guidelines for Systems For Handling Oily Wastes in Machinery Spaces”
• ASTM F2283-04 “Standard Specification For Shipboard Oil Pollution Abatement System”
COFFIN WORLD WATER SYSTEMS
MEPC 107(49) Attributes Tested
• Oil Output Less Than 15 PPM Using 3 Test Fluids– Determined by Laboratory Test of Output
• Unit Capacity – Based On Flow Rate During Test, Using Specified Test
Fluids, Concentrations And Test Durations
• Continuous And Automatic Operation– Determined By Continuous Operation Without Human
Intervention During Test
• Operation In Shipboard Environmental Conditions– Determined By Laboratory Testing Including Vibration
Temperature Humidity And Inclined Operation
COFFIN WORLD WATER SYSTEMS
• Test Fluids/Test Minimum Duration • Test Fluid A - marine residual fuel/ 3.75 Hours• Test Fluid B - marine distillate fuel/ 1 Hour• Test Fluid C - an emulsion/ 2.5 Hours
• Fluid Type “C” was added to certification test requirements. This fluid contains at least 3,000 ppm of emulsified oil and 100 PPM of Solids

Future Testing Recommendations
– Separator Tested Together With Monitor– Fluid Temperature Be More Precisely
Specified And Emulsion Be More Stable And Consistent Between Tests
– Continuous Running Be Better Monitored
– Configuration Control of Production Systems
COFFIN WORLD WATER SYSTEMS
IMO MEPC.1 Circ 642
• 2008 Revised Guidelines for Systems For Handling Oily Wastes in Machinery Spaces– Minimize Oily Bilge Water
• Separate Clean Drains• Route Oily Drains Direct to Oily Residue (Sludge)
Tanks
– Pre-treatment with Bilge Primary Tanks• Attempts To Minimize The Variation In Bilge

ASTM F2283-04
• Suggested Revisions– Standardize Terminology To Conform With
IMO– Expand Bilge Management Section To Create
A Bilge System Design Section – Requirements Should Be Technology Neutral – Be Less Prescriptive In Equipment Design
Features – Minimize The References To Other Documents– Notional System Diagram Be Updated to take
into account MEPC 107(49) equipment and MEPC.1 Circ.642
