“+”(properly called a Pattee cross but often called a Maltese cross) means the ship was constructed under survey by Lloyd's Register surveyors; "100" means the ship is suitable for seagoing service. "A" means the ship was constructed or accepted into LR class and is maintained in good and efficient condition. "1"means she has good and efficient anchoring and mooring equipment.

A more detailed inspection must be carried out, including further checking of compliance with on-board operational requirements, if the Port State Control Officer has clear grounds for believing, after the initial inspection, that the condition of a ship or of its equipment or crew does not substantially meet the relevant requirements of a Convention. "Clear grounds" will exist when the PSCO finds evidence which in his professional judgment warrants a more detailed inspection of the ship, its equipment or its crew.

For example: costs of hiring a tug to refloat a stranded ship with cargo onboard; cost of discharging cargo in order to refloat a stranded ship or to carry out repairs at a port of refuge; salvage costs; agency fees at a port of refuge; surveyors' fees; warehousing charges; port charges; master's and crew's wage while a ship is being repaired; and Average Adjuster's fee.

 

Under section 9. 8 of the ISPS Code, ship security plans are not subject to inspection by officers duly authorized by a Contracting Government to carry out control and compliance measures in accordance with regulation XI-2/9, except in circumstances specified in section 9. 8.1. Section 9.8.1 provides that if the officers duly authorized by a Contracting Government have clear grounds to believe that the ship is not in compliance with the requirements of SOLAS chapter XI-2 or part A of the ISPS Code, and the only means to verify or rectify the non-compliance is to review the relevant requirements of the ship security plan, limited access to the specific sections of the plan relating to the non-compliance is exceptionally allowed, but only with the consent of the Contracting Government of, or the master of, the ship concerned. Nevertheless, the provisions in the plan relating to section 9. 4 subsections. 2,. 4,. 5,. 7,.15, . 17 and. 18 of Part A of the Code are considered as confidential information, and cannot be subject to inspection unless otherwise agreed by the Contracting Governments concerned. (ISPS Code, 9. 8. 1)
