ABS Publishes 1980 Rules On Building And Classing Offshore Drilling Rigs

The American Bureau of Shipping (ABS) has published the 1980 edition of Rules for Building Building and Classing Mobile Offshore Drilling Units. The "Rules" will be applicable to units contracted after November 1, 1980.

In this third edition, there is a new appendix containing specific material selection guidelines applicable to any mobile offshore drilling unit based on the type of unit and intended operating environment. Another new appendix describes the procedures and conditions under which a properly conducted underwater inspection of a mobile offshore drilling unit may be credited as a drydocking survey.

The section of the "Rules" concerning surveys after construction has been considerably expanded to include detailed descriptions of hull areas and machinery subject to ABS survey.

There is extensive updated information in sections that describe standards regarding watertight bulkheads and flats, welding, machinery, pumps and piping systems, electrical installations, and safety features.

Copies can be ordered ($20 each) from the Book Order Section, American Bureau of Shipping, 65 Broadway, New York, N.Y. 10006, or from other ABS offices.
