2、5 Northchase Drive Houston, TX 77060 USA Foreword Foreword This Guide has been prepared to provide Owners guidelines for the lay-up and reactivation of Offshore Support Vessels (OSVs). These guidelines are of a general nature due to the wide variety of OSV configurations and degree of maintenance du
3、ring lay-up. This Guide expands the “Laid-up” status to provide more precise definitions regarding exact status of a stacked vessel. This Guide provides the following three options for laid-up life cycle status for vessels classed with ABS: i) Laid-up with no record comment ii) Laid-up with the foll
4、owing record comments: a) Laid-up Warm Stacked b) Laid-up Cold Stacked These conditions will be noted in the vessels survey status and the Record. The goal of having a vessel enrolled with a record comment is to clearly identify its state of readiness. This Guide becomes effective on the first day o
5、f the month of publication. Users are advised to check periodically on the ABS website www.eagle.org to verify that this version of this Guide is the most current. We welcome your feedback.

12、 will review, survey, and confirm by issuance of a factual Lay-up Report, the actions taken to preserve and protect a vessel 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
13、. 1 General i) Upon the Owners written notification to ABS of a vessels lay-up, it will be noted in the vessels 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 vessel reactivates, at which time
14、they are to be brought up to date. ii) The Reactivation Survey requirements for the vessel 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 vessel has been maintained during
15、 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 lay-up from the progression of survey intervals, or to modifying the requirements for up-dati
16、ng surveys at time of reactivation. iv) There are three conditions for a vessel 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. These condition
17、s are described in Subsection 1/3. 3 Definitions 3.1 Life Cycle Status “Laid-up” All laid-up vessels will have a Life Cycle Status of “Laid-up”. When a vessel has a “Laid-up” Life Cycle Status in the Record without any additional record comment, this means that the vessel is out of service for an un
18、determined length of time. The Owners have informed ABS that the vessel is laid up, but no procedures for lay-up have been reviewed by ABS. While in laid-up status, class surveys are held in abeyance and statutory surveys are maintained when required by the flag Administration. Prior to returning to
19、 service, a Reactivation Survey in accordance with Section 3 of this Guide, including all due and overdue Class and Statutory Surveys, is to be carried out. An Initial Lay-up Verification Survey and Annual Surveys are not required for this Life Cycle Status and no attendant record comment. Vessels w
20、ith lay-up procedures, initial verifications surveys, and periodic examinations verified by ABS will have additional record comments describing the type of lay-up as listed below. 3.3 Laid-up with Record Comment “Laid-up Warm Stacked” When a vessel has a “Laid-up Warm Stacked” record comment in the
21、Record, this means the vessel is not in operation, is positioned in a sheltered location and there is a crew onboard carrying out the maintenance and preservation activities described in the ABS agreed lay-up procedure. In this case, 1/1iii) is applicable. Class surveys are held in abeyance and stat
22、utory surveys are maintained when required by the flag Administration. However, Annual Lay-up Surveys are required to be carried out. Prior to returning to service, a Reactivation Survey taking into account the degree of maintenance conducted while laid-up, including all due and overdue Statutory Su
23、rveys, are to be carried out. ABSGUIDE FOR LAY-UP AND REACTIVATION OF OFFSHORE SUPPORT VESSELS .2017 1 Section 1 General 3.5 Laid-up with Record Comment “Laid-up Cold Stacked” When a vessel has a “Laid-up Cold Stacked” record comment in the Record, this means that the vessel is not operating, is pos
24、itioned in a sheltered location, is unmanned, and that the lay-up procedures have been reviewed by ABS. In this case, 1/1iii) is applicable. All Class and Statutory Surveys are held in abeyance. However, Annual Lay-up Surveys are required to be carried out. Prior to returning to service, a Reactivat
25、ion Survey taking into account the degree of maintenance conducted while laid-up, including all due and overdue statutory surveys, are to be carried out. 5 Lay-up Surveys When a vessel is laid-up with a “Laid-up Warm Stacked” or “Laid-up Cold Stacked” record comment in the Record, an Initial Verific
26、ation Survey is required. After being laid-up, the vessel will also be subjected to periodic surveys. The scope of such surveys will consist of verification of all items on the ABS agreed lay-up procedure. In the case of “Laid-up Cold Stacked” vessels, in addition to the verification detailed in Sub
27、section 2/5, the equivalent to an Annual Hull Survey is to be carried out. In the case of “Laid-up Warm Stacked” vessels, in addition to the verification listed in Subsection 2/5, the equivalent to an Annual Hull Survey and an Annual Machinery Survey is to be carried out. 7 Maintenance of Record Com
28、ment When the vessel has a record comment of “Laid-up Warm Stacked” or “Laid-up Cold Stacked” the vessel will not be eligible for deduction of any time in lay-up from the survey cycle in any of the following circumstances: i) If the periodical surveys required for maintenance of the record comment a
29、re not carried out by their due dates and no extension has been granted ii) If recommendations issued by the Surveyor regarding degree of compliance with the lay-up procedure are not carried out by their due dates and no extension has been granted iii) If any damage, failure, or repair has not been

33、s to vessels requesting a record comment of “Laid-up Warm Stacked” or “Laid-up Cold Stacked.” 1 Lay-up Procedure Requirements Lay-up procedures submitted to ABS are to contain the following information for each vessel: i) General description of the lay-up plan a) Location of the vessel while laid-up
34、 b) Description of the mooring c) Number of personnel expected to be on board d) Description of any external verification such as security personnel or vessel patrols ii) List of systems active while laid-up iii) List of systems partially active while laid-up iv) List of systems shut down and preser
35、ved while laid-up v) Procedures for preserving each system that is shut down vi) Procedures for tracking overdue maintenance or parts required for reactivation vii) Procedures for periodic maintenance of preservation while laid-up viii) Plans for backup and storage of vessel system software 3 Fire a
36、nd Safety Requirements for all Laid-up Vessels i) All the vessels fire safety equipment including emergency fire pump are to be proven in good order immediately prior to lay-up and maintained ready for immediate use thereafter. ii) The vessels fire extinguishing piping is to be proven in good condit
37、ion. If the piping is drained, drains are to be kept only sufficiently open to allow drainage of condensate. Alternatively, the fire main lines may be filled with inhibited fresh water, including anti-freeze if necessary, or left in service. The international shore connection, where provided, is to
38、be loosely installed and its location prominently marked. Fire line valve stems are to be freed up and lubricated. iii) All ventilators and air intake or exhaust openings for spaces not active are to be adequately covered. Supply and exhaust openings for necessary emergency diesel generator or fire
39、pump engines are to be arranged for immediate or automatic opening. iv) A source of power for providing emergency lighting, fire extinguishing water, and bilge pumping throughout the vessel is to be immediately available. Where the emergency source of power is a portable diesel generator set mounted
40、 on deck, adequate arrangements are to be made to install and secure the equipment, including fire safety of the fuel and exhaust systems, fire extinguishing arrangements, weather protection, proper electrical installation, and electrical protective devises for the vessel to the satisfaction of the
41、attending Surveyor.
