What would be the proper procedure where a ship is operating at a higher security level than the port facility it is arriving at?

The Ship Security Officer (SSO) should advise the Port Facility Security Officer (PFSO) without delay. The PFSO should undertake an assessment of the situation in consultation with the SSO and agree on appropriate security measures with the ship, which may include completion and signing of a Declaration of Security. Any costs entailed in additional security measures would be settled by the ship.
