16.1.1 In
                                 all areas where mechanical damage might be likely, all side scuttles,
                                 scuppers and discharges, including their valves, controls and indicators,
                                 are to be well protected. Consideration is to be given to the likelihood
                                 of impact damage to scuttles and discharges due to barges coming alongside,
                                 and to scuppers becoming blocked by sand or other spoil which may
                                 spill onto the decks or other areas being drained.
                              
                              
                              
                            
                           
                           
                           
                              
                              
                              16.1.2 Consideration
                                 will be given to requests for relaxation of requirements relating
                                 to scuttles, scuppers and discharges on ships classed A1 protected
                                    waters service.
