These guidelines are of a general nature due to the wide variety of MODU configurations, geographic and climatic conditions of lay-up sites and degree of maintenance during lay-up, and are therefore intended solely for guidance purposes.

5、 UNITS If requested by the Owner, the American Bureau of Shipping will undertake to review, survey and confirm by issuance of a factual Lay-up Report, the actions taken to preserve and protect a unit in lay-up. Outlined below are precautions and procedures suggested to accomplish this objective, how
6、ever it is recognized that there may be a variety of equally satisfactory approaches to accomplish the same objective. 1.1 LAY-UP SURVEYS 1.1.1 1.1.2 1.1.3 When the Bureau is notified by the Owner that a unit has been laid-up, this status will be noted in the units survey status and in the RECORD, a
7、nd surveys falling due during lay-up may then be held in abeyance until the unit reactivates at which time they are to be brought up-to-date. Please refer to 6.1 for details. In the case of units which have been laid up for an extended period (six months or more), the requirements for the Reactivati
8、on Survey are to be specially considered in each case, due regard being given to the status of surveys 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. Where the initial lay-up preparations and
9、 procedures have been submitted to the Bureau for review and survey, and re- 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-dating surveys at time of reactivation
10、. 2.1 CERTIFICATION STATUS Some flag Administrations (e.g. Panama, Liberia, USCG) require that all Classification Surveys on laid-up units be kept up-to-date if the Owner wishes to maintain a valid IMO MODU Code Certificate or International Loadline Certificate. If the MODU Code or Loadline Certific
11、ate is allowed to expire during lay-up then a complete initial-certification type survey may be required by these Administrations at the time of reactivation. All Owners of laid-up units with U.K. Department of Energy (DEN) Certificates should be aware that if the DEN Certificate is allowed Copyrigh

If so requested therefore, ABS will continue DEN surveys while a unit ia in lay-up. Functional, system, safety and electrical testing

ABS recommends that the Owner of any unit that has been certified to national or international requirements make provisions to keep related survey requirements up-to-date in order to avoid problems as mentioned above. 3 . 1 SAFETY AND PROTECTION 3.1.1 3 . 1
15、 . 2 3.1.3 3.1.4 Sufficient and qualified personnel should be available in order to maintain full-time fire, leakage, moorings and security watch of the unit. In addition, efficient independently-powered fire and bilge flooding alarms with exterior warning lights should be fitted for the machinery s
16、paces, bilges and for other locations as deemed appropriate. The available watchmen should include a barge engineer and other personnel capable of operating the emergency communications equipment and taking emergency action pending arrival of outside assistance for fire extinguishing, leakage pumpin
17、g, mooring adjustment or release, and general security. This includes the operation of the necessary emergency power sources, pumping units and any active fixed fire control apparatus. Qualified personnel for emergency ballasting in hurricane areas should be considered. All the units fire safety equ
18、ipment including emergency fire pump should be proved in good order immediately prior to lay-up and maintained prepared for immediate use thereafter. The units fire lines should be proved in good condition before draining. Drains should then be kept only sufficiently open to allow drainage of conden
19、sate. Alternatively, the fire lines may be filled with inhibited fresh water, including anti-freeze if necessary. The International Shore Connection should be loosely installed and its location prominently marked. Fire line valve stems should be freed- up and lubricated. Oxygen breathing apparatus a
20、nd flotation escape equipment should be provided and maintained immediately available for the watchmen or lay-up crews.
