General

At the request of the owner and to assist in the maintenance of class, ABS will review, survey, and confirm by issuance of a factual Lay-up Report, the actions taken to preserve and protect a unit in lay-up. This Guide contains those precautions and procedures considered by ABS to accomplish this objective; alternative approaches to accomplish the same may be considered.

i) Upon the owner's written notification to ABS of a unit's lay-up, it will be noted in the unit's survey status and the Record will be updated to reflect the change in status. Surveys falling due during lay-up are then to be held in abeyance until the unit reactivates, at which time they are to be brought up to date.

ii) The Reactivation Survey requirements for the unit are subject to special considerations based on the survey status at the time of the commencement of lay-up, the length of the lay-up period, and the conditions under which the unit has been maintained during that period.

iii) Where initial lay-up preparations and procedures are reviewed and surveyed by ABS, and also verified annually by survey, consideration may be given to deducting part or all of the time in layup from the progression of survey intervals, or to modifying the requirements for up-dating surveys at time of reactivation.

iv) There are three conditions for a Unit with a Laid-up "Life Cycle State" in the Record, Laid-up with no Record Comment; Laid-up Warm Stacked with the corresponding Record Comment and Laid-up Cold Stacked with the corresponding Record Comment. The Record Comments "Laid-up Warm Stacked" and "Laid-up Cold Stacked" can also have the Enhanced modifier, to have Record Comments showing "Enhanced Laid-up Warm Stacked" and "Enhanced Laid-up Cold Stacked". These conditions are described in Subsection 1/3 below.
