دانلود کتاب توصیه 87 – رهنمودهایی برای نگهداری و تعمیرات پوشش مخازن بالاست و مخازن ترکیبی محموله/بالاست روی تانکرهای نفت

The principal objective of IACS is to set the technological standard for ships, in order to secure safety of life, property and environment at sea. With these Guidelines, IACS aims at assisting the Surveyors, Owners, Yards, Flag Administrations and other interested parties involved in the survey, assessment and repair of coatings in ballast tanks and combined cargo/ballast tanks herein referred to as “ballast tanks” on tankers.
Considerable space is dedicated, in these Guidelines, to definitions and description of terms (Appendix E) aiming at:
• describing every term which is used in these Guidelines and other commonly used terms, and
• providing, through a common language, the basis for a common understanding.

It is therefore suggested that Class Surveyors and Inspectors of Owners, Yards, Administrations and Manufacturers use, as far as possible, these definitions.
The motivation for developing these Guidelines is the revision of the IACS UR Z10.1, Z10.3 and Z10.4, which imply that coating found in less than GOOD condition is repaired or maintained in order to avoid annual survey. These Guidelines address a clear definition of GOOD coating condition and how to restore from FAIR and/or POOR conditions to GOOD respectively.
The basis for developing these Guidelines has been several Tanker Structure Co-operative Forum (TSCF) publications (see Reference), accordingly some text and illustrations have been reproduced directly in these Guidelines. TSCF assistance in the development of these Guidelines and permission to use such material is gratefully acknowledged.
