13.1 Design appraisal, installation and testing

13.1.1 The design appraisal is to be carried out based on the contents of the Winterisation Manual, see Ch 1, 1.3 Information required. The Winterisation Manual is to contain sufficient details to demonstrate compliance with these Rules to the satisfaction of the Surveyor.

13.1.2 For assignment of the Winterisation notation the design appraisal is to be carried out to assess that the contents of the Winterisation Manual demonstrate compliance with these Rules. It is not intended to confirm the technical details of the Winterisation features nor provide verification of the systems and equipment.

13.1.3 During design appraisal, installation and testing, the Winterisation features are to be considered in conjunction with the requirements of the National Authority with which the ship is registered and/or the Administration within whose territorial jurisdiction it is intended to operate, and the relevant international conventions, as far as applicable, such that the Winterisation features do not conflict or form restrictions with statutory requirements. See Ch 1, 1.1 Scope and Ch 1, 1.2 Application.

13.1.4 During design appraisal, installation and testing, the Winterisation features are to be considered such that they do not compromise or impair the operation of the equipment or systems.

Structural items, equipment and fittings are to be installed and tested in accordance with an agreed plan to the satisfaction of the Surveyor. The installation and testing is to demonstrate activation and operation; they are not intended to confirm the performance of the systems, equipment and fittings at the design temperatures.

13.1.6 Following successful completion of the survey, the Winterisation notation may be assigned to the ship. The Winterisation notation will be valid, in the first instance, for a period not exceeding 12 months.
