Any Owner/Operators specific request for compliance with applicable requirements of flag or Coastal State Authorities affecting the drilling systems is to be filed as an addendum to the Request f
6、or Classification. The 2017 edition of the Guide for the Classification of Drilling Systems is an updated version of the 2012 edition of the subject Guide. The first edition of the CDS Guide was published in 1986 to support the drilling regulations developed for rigs operating in the UK sector of th
7、e North Sea. As part of ABSs commitment to promoting the security of life and property and preserving the natural environment, ABS has endeavored to continuously update the Guide by applying the latest industry standards and trends in risk abatement. Previous Sections of this Guide have been reforma
8、tted to Chapters and each Chapter has been updated in accordance with the latest industry standards and practices as well as ABS plan review and survey practices.
