Statutory Documents - IMO Publications and Documents - Circulars - Maritime Safety Committee - MSC.1/Circular.1455 – Guidelines for the Approval of Alternatives and Equivalents as Provided for in Various IMO Instruments – (24 June 2013) - Annex – Guidelines for the Approval of Alternatives and Equivalents as Provided for in Various IMO Instruments - 7 Operation - 7.1 Requirements pertaining to the operation of ships that have approved alternatives and/or equivalencies

7.1 Requirements pertaining to the operation of ships that have approved alternatives and/or equivalencies

  7.1.1 This section of the Guidelines considers special requirements that apply to the operation of ships with approved alternatives and/or equivalencies onboard. In particular, the requirements for documentation on board such ships are addressed as well as requirements for change of flag.

  7.1.2 Depending on the particular design of the alternative and/or equivalency, conditions for maintaining the safety level intended during the design approval may be imposed on ship operation. Such conditions may be restrictions and limitations on the type of operations and trades the ship can engage in or it may be additional safety procedures or measures that need to be in place. Any operational conditions should be determined during the approval process and be based on the outcome of the HazId and the risk assessments undertaken as a part of the process described in these Guidelines, and they should be clearly documented and communicated to relevant parties.

  7.1.3 If, during the operational phase, the initial assumptions made during the design approval are changed, i.e. a change of any aspects of the operation that may influence the risk, it may be necessary to repeat the part of the risk assessment with the adjusted assumptions. Such needs and the extent of work needed will be dependent on the risk-based features, the assumptions changed and the operation of the ship and may be decided by the relevant administration.

  7.1.4 During the operational phase, inspections and surveys on these ships will be performed as on conventional ships. It is therefore important that the features of the alternative and/or equivalent design and possible operational conditions are taken into account and understood by the Administration. Thus, clear documentation on the alternative and/or equivalent design should be kept on board. In the following, the requirements for onboard documentation are outlined.

  7.1.5 Amendments to the Safety Management System may be required to integrate the evaluation of any changes in the risk levels. Recurring review of the operational environment may be a requirement and this may be stipulated as an element in the periodic company review and masters' review.
