Keywords: Aluminum pipeline, Arctic storage tank 



Article describes the construction of an 8-inch-diameter aluminum pipeline from an 

 anchored ship to a storage tank in the Arctic. The pipe sections were welded and 

 pressure-tested onshore, and pulled out on the surface by a winch on a work boat stationed 

 offshore. The pipeline was then sunk by pumping in water, and saddle-type anchors were 

 placed by a crane and divers to compensate for the buoyancy and to stabilize the pipeUne.

Keywords: Corrosion, Offshore pipelines. Weld hardness 



Proceedings paper discusses an investigation of the effect of weld hardness on the 

 cracking susceptibility of offshore pipelines due to stress corrosion or hydrogen sulfide 

 cracking. Automatic welding and sulfate reducing bacteria are briefly discussed as they 

 apply to this investigation. Laboratory cracking tests were made in which stresses were 

 appUed to several weld specimens exposed to a corrosive environment of saltwater 

 containing hydrogen sulfide. The hardness of the welds was determined after the cracking 

 tests. The experimental setup and testing procedure are discussed, along with the results of 

 the tests. Recommended hardness Umits for pipeline field welds are given from the results of 

 the investigation.

 System," Journal of the Power Division, VoL 82, No. POl, Feb. 1956, pp. 1-19. 



Keywords: Cooling water system, Steel pipeline. Thermal power system, Trombay Island, 

 India 

 Paper describes the design and construction of the cooling water system for a thermal 

 power station on Trombay Island in Bombay Harbor, India. The cooling water system 

 consists of a cast-in-place, reinforced concrete underground conduit leading into the power 

 station, followed seaward by a steel pipeline supported first by concrete saddle piers resting 

 on an earth embankment over the tidal flat area, and then supported by a rockfill 

 embankment, extending into the harbor about 1,100 feet offshore. This leads to a 

 reinforced concrete trestle which carries the pipeline above water to the offshore intake 

 structure. The intake structure was designed to be constructed in drydock as a reinforced 

 concrete caisson, which was floated to the site and sunk to position.
