1 COFFIN WORLD WATER SYSTEMS Standards for Handling Oily Wastes in Machinery Spaces Lou Mazzarone Coffin World Water Systems

2 COFFIN WORLD WATER SYSTEMS OILY WATER SEPARATOR (OWS) DESIGN DRIVERS Certification Price Performance Ease Of Operation Reliability Maintainability Cost Of Operation

3 COFFIN WORLD WATER SYSTEMS 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

4 COFFIN WORLD WATER SYSTEMS EXAMPLES OF OWS TECHNOLGIES IN USE Separation Technologies –Membranes –Coalescing –Centrifuges –Adsorption –Flocculation

5 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 Revised Guidelines for Systems For Handling Oily Wastes in Machinery Spaces ASTM F Standard Specification For Shipboard Oil Pollution Abatement System

6 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

7 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 TYPE FLUID C TYPE FLUID B TYPE FLUID A CLEAN DISCHARGE WATER Sample USCG test fluids and ULTRA-SEP discharge water MEPC 107(49) Testing

8 COFFIN WORLD WATER SYSTEMS What Test Fluid Is Appropriate? Actual Bilge –Wide Variations Ship To Ship –Wide Variations On A Given Ship Day to Day TDSTSSTO&GCO6C10C22Fe MIN PPM ND 41.2 AVG. PPM MAX PPM Actual Bilge 50 Samples At OWS Inlet

9 COFFIN WORLD WATER SYSTEMS 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

10 COFFIN WORLD WATER SYSTEMS IMO MEPC.1 Circ 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 Presented To The OWS

11 COFFIN WORLD WATER SYSTEMS IMO MEPC.1 Circ 642

12 COFFIN WORLD WATER SYSTEMS IMPACT OF IBTS

13 COFFIN WORLD WATER SYSTEMS ASTM F –Shipboard Oil Abatement System Looks At The Entire Ship Bilge Processing System Of Which The Oily Water Separator Is Part Under Revision

14 COFFIN WORLD WATER SYSTEMS F Notational System Diagram

15 COFFIN WORLD WATER SYSTEMS ASTM F 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
