5.1 A Declaration of Security (DoS) should be
                           completed when the Contracting Government of the port facility deems
                           it to be necessary or when a ship deems it necessary.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5.1.1 The need for a DoS may be indicated by the
                           results of the port facility security assessment (PFSA) and the reasons
                           and circumstances in which a DoS is required should be set out in
                           the port facility security plan (PFSP).
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5.1.2 The need for a DoS may be indicated by an
                           Administration for ships entitled to fly its flag or as a result of
                           a ship security assessment (SSA)and should be set out in the ship
                           security plan (SSP).
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5.2 It is likely that a DoS will be requested
                           at higher security levels, when a ship has a higher security level
                           than the port facility, or another ship with which it interfaces,
                           and for ship/port interface or ship– to– ship activities
                           that pose a higher risk to persons, property or the environment for
                           reasons specific to that ship, including its cargo or passengers or
                           the circumstances at the port facility or a combination of these factors.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5.2.1 In the case that a ship or an Administration,
                           on behalf of ships entitled to fly its flag, requests completion of
                           a DoS, the PFSO or SSO should acknowledge the request and discuss
                           appropriate security measures.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5.3 A PFSO may also initiate a DoS prior to ship/port
                           interfaces that are identified in the approved PFSA as being of particular
                           concern. Examples may include the embarking or disembarking passengers,
                           and the transfer, loading or unloading of dangerous goods or hazardous
                           substances. The PFSA may also identify facilities at or near highly
                           populated areas or economically significant operations that warrant
                           a DoS.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5.4 The main purpose of a DoS is to ensure agreement
                           is reached between the ship and the port facility or with other ships
                           with which it interfaces as to the respective security measures each
                           will undertake in accordance with the provisions of their respective
                           approved security plans.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5.4.1 The agreed DoS should be signed and dated
                           by both the port facility and the ship(s), as applicable, to indicate
                           compliance with chapter XI-2 and part A of this Code and should include its
                           duration, the relevant security level, or levels and the relevant
                           contact details.
                           
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5.4.2 A change in the security level may require
                           that a new or revised DoS be completed.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5.5 The DoS should be completed in English, French
                           or Spanish or in a language common to both the port facility and the
                           ship or the ships, as applicable.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           5.6 A model DoS is included in Appendix 1 to this Part of the Code.
                           This model is for a DoS between a ship and a port facility. If the
                           DoS is to cover two ships this model should be appropriately adjusted.
