difficulty of replacement of sacrificial anodes. The steel pipe was coated with coal-tar 

 enamel, fiberglass reinforcing, and bonded asbestos felt. A steel mesh-reinforced cement- 

 mortar shield was applied over tlie coating, and cement mortar was also used to line the 

 inside of the pipe. The pipe sections were assembled onshore and pulled out to sea by barge. 

 A cathodic protection was used during the installation of the pipeline, which provided 

 continuous testing to detect any damage to the coating. This testing made repairs possible 

 before the pipe was laid at inaccessible depths on the sea bottom.

Article describes a reel-type pipelaying barge designed to lay 4- to 12-inch-diameter 

 heavy- walled steel pipe. The design of the reel and associated pipe-handling equipment are 

 described, and the results of tests to determine the effects of reversed bending on the pipe 

 during the reeUng and unreeling processes are summarized.

Keywords: Reel-type pipelaying barge, Thick -walled steel pipe 



A reel-type pipelaying barge capable of laying thick-walled steel pipe with diameters 

 up to 12 inches is described. The advantages of this pipe-laying technique are discussed, and 

 the basic components of the reel pipe-laying system are described. A brief summary of the 

 results of technical investigations of particular concern to this pipelaying method, including 

 low cycle fatigue, weld ductility, ovahng of the pipe, straightness of the pipe, and tlie 

 minimum radius of tlie reel, is also included.

 Offshore Engineering Development," Symposium on Offshore Hydrodynamics, Apr. 

 1972. 



Keywords: Elastic similarity models. Offshore engineering development 



A discussion is presented of the elastic similarity modeling techniques as applied to the 

 study of the interaction between hydrodynamic forces and structural behavior of offshore 

 structures. Scale relationships are derived and briefly discussed for water currents in closed 

 conduit flow, currents and waves at free surface conditions, and elastic structures in water; 

 the scaling laws of the hydraulic models are combined with the relationship expressing the 

 elastic behavior of the structures. The compromises that must be made with respect to 

 elasticity, mass, and dampening, as a result of the practical considerations and materials 

 available for modeling, are discussed. Applications of elastic similarity models to the study 

 of offshore pipelines and driUing platforms are discussed as examples.
