15. 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
