Keywords: Coatings, Reel-type pipelaying barge 



Article describes the operation and performance of a reel-type pipelaying barge 

 capable of laying 12-inch-diameter pipelines. The pipe-handling and pipe-straightening 

 equipment is described. Tests were conducted to evaluate the effects of strain reversals due 

 to the spooling and unspooling of the pipe on the properties of the pipe, including ovaling, 

 tensile properties, and weld ductility; the results of these tests are discussed. Coatings for 

 corrosion protection of reeled pipeUnes are discussed, along with problems due to coating 

 defects and damage arising from the reeling and pipelaying operations.

A reel-type pipelaying barge that can lay thick- walled steel pipelines up to 12 inches in 

 diameter is described. The pipelaying procedure, the design of the pipe-handling equipment, 

 and problems involving damage to the plastic pipe coatings are also discussed.

Proceedings paper describes a welding system in which high-quality, high-strength 

 welds are obtained in tapping newly fabricated pipelines to existing pipeUnes. The welding is 

 done in a dry, high-pressure environment similar to land-based operations, with the use of a 

 specially designed underwater welding chamber capable of handling pipes up to 24 inches in 

 diameter. It is used in conjunction with a submersible decompression chamber to transport 

 the welders from the boat to the welding chamber at the bottom.

Paper describes the design and construction of the corrosion protection system used in 

 the Hyperion ocean outfall in Los Angeles, Cahfomia. The corrosion protection system was 

 designed to provide a useful Ufe of at least 100 years, because the steel pipeUne is 

 terminated in water too deep to make it accessible to the conventional diving methods used 

 to inspect, test, and repair submarine pipelines. An impressed current corrosion protection 

 system was used rather than sacrificial anodes, due to the relatively short lifetime and the
