                           MARPOL Annex I contains
                           certain regulations and unified interpretations related to equipment
                           for the storage, handling and disposal of oily residues (sludge) and
                           engine-room oily bilge water.
                           
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           2 In order to facilitate the work of Administrations
                           on systems for handling oily wastes in machinery spaces of ships,
                           the Marine Environment Protection Committee (MEPC) has continuously
                           reviewed the available technologies for fulfilment of the Convention
                           requirements.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           3 The Revised Guidelines for systems for handling
                           oily wastes in machinery spaces of ships incorporating guidance notes
                           for an integrated bilge water system (IBTS) appended to MEPC.1/Circ.511 were adopted by MEPC 54
                           as guidance for Administrations, shipowners and shipbuilders for consideration
                           in achieving an efficient and effective system for the handling of
                           oily bilge water and oily residues for ships taking into account the
                           entry into force of the revised MARPOL Annex
                              I on 1 January 2007.
                           
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           4 Recognizing that the entry into force of MARPOL Annex VI, including its provisions
                           for shipboard incineration of sludge oil generated during the normal
                           operation of a ship, has called for a further revision of the Guidelines,
                           as contained in MEPC.1/Circ.511, the
                           Marine Environment Protection Committee, at its fifty-eighth session
                           (6 to 10 October 2008), approved the 2008 Revised Guidelines for systems
                           for handling oily wastes in machinery spaces of ships incorporating
                           Guidance notes for an integrated bilge water treatment system (IBTS)
                           (MEPC 58/23, paragraph 10.45). The 2008 Revised Guidelines, set out
                           in the annex, supersede and replace the Revised Guidelines appended
                           to MEPC.1/Circ.511.
                           
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5 To ensure compliance with the provisions on
                           oil residue (sludge) collection and disposal of MARPOL
                              Annex I, the process of regeneration of fuel oil from oil residue
                           (sludge) has been defined and included in the Guidance notes for an
                           integrated bilge water system (IBTS) appended to the Guidelines.
                           
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           6 A recommendation regarding internal drain tanks
                           for oily residue (sludge) and other oily residues, which can only
                           be discharged to the vessel's oily residue (sludge) tanks has been
                           included in order to simplify the required records in the Oil Record
                           Book.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           7 Member Governments are invited to apply the
                           revised Guidelines and to bring them to the attention of interested
