The Maritime Safety Committee

  1 The Maritime Safety Committee, at its seventieth session 7 to 11 December 1998, approved the Guidelines for the on-board use and application of computers given in the annex. Also, the Committee, at its sixty-ninth session (11 to 20 May 1998), approved MSC/Circ.854 on Guidelines for shipboard loading and stability computer programmes and instructed the Secretariat to annex them to the aforementioned Guidelines for the on-board use and application of computers, once approved. The former have, therefore, been attached to the latter and are set out in the appendix to the annex.

  2 The advent of inexpensive personal computers has resulted in rapidly-growing usage aboard merchant marine vessels for many shipboard applications, including cargo loading and trim and stability calculations. To the extent that these programmes rely upon human input of data and interpretation of output, they are potentially vulnerable to human factor errors. Although such errors will most likely emerge in the user such as shipboard officers, the actual roots of the errors might be found in other shoreside sectors; software developers who might not anticipate human factor needs, or shipping company management.

  3 Requirements as to the performance of such software will depend on the person/organization involved as follows:

  • .1 For users (ship officers): greater consistency among programmes from different vendors, which will make familiarization and proficiency easier and faster to achieve;

  • .2 For ship owners/operators: availability of well-conceived software products that include appropriate materials for training and also documentation for revising programme or data when necessary, for instance to reflect any changes in the ship's weight and moment characteristics;

  • .3 For software developers: the benefit of a broader experience base than just their own corporate experience, and a consistent uniform standard reflecting customer expectations; and

  • .4 For Administrations: assurance that sophisticated programmes are developed and introduced into service and that they will reflect human factor considerations and minimize chances for human error.

  4 These Guidelines for the on-board use and application of computers have been developed to provide an international standard for the design, approval and testing of such systems and should be construed as supplementary to the relevant regulations of the SOLAS Convention. However, it should be noted that certain applications of computers are defined in Performance Standards adopted by the Organization which take precedence over these Guidelines.

  5 Taking into account that the number and types of computer-based systems available for on-board use is strongly increasing, that such systems are under fast development and the fact that they have considerable effect on the safety at sea, the international harmonization should be beneficial to manufacturers, ship builders, ship owners and ship operators, maritime administrations and organizations acting on their behalf, seafarers, passengers and other users of marine services.

  6 The Guidelines are not intended to prohibit the use of any existing computer-based systems on board existing ships if such systems do not fully comply with these Guidelines. Many existing ships have operated their computer-based systems successfully and safely for a long period of time, and their operating history should be considered in evaluating their suitability to continue contributing to their safe operation.

  7 For existing systems, the Guidelines should be made applicable to a reasonable extent when major modifications are carried out.

  8 Where these Guidelines refer to the Administration, this is the flag State Administration or a recognized organization authorized to act on its behalf in accordance with SOLAS regulation XI/1.

  9 Member Governments, CIRM, IEC, IACS, ICS and all other interested parties are requested to bring the attached Guidelines to the attention of all concerned.
