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 Presented To The OWS

COFFIN WORLD WATER SYSTEMS

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
