Keywords: Construction insurance, Offshore pipeline 



Construction insurance on the capital works and liabilities of coastal construction 

 projects involving water risks, such as harbors and offshore pipelines, is discussed. The extent 

 of typical coverage for both damage insurance and public Uability policies is listed 

 separately, along with the normal restrictions and exclusions that go with each type of 

 insurance. Detailed information concerning the construction project must be supplied to the 

 insurers before they decide to accept a particular risk, and if so, on what terms, conditions, 

 and premium rating levels. This information is also outlined in the paper.

Keywords: Concrete coating. Submarine pipeline 



Tests are described which determine the effects of concrete coating on the flexural 

 rigidity of submarine pipelines subject to bending stresses during construction operations, 

 and also the effects of joints on the behavior of pipe. The results of the tests are discussed 

 and several graphs illustrating the results of the test data are presented.

Keywords: Bending stresses, Ovaling 



Paper discusses an investigation of the ovahng effect on the flexural behavior of 

 pipelines stressed beyond the elastic limit. Several pipe sections, uncoated and coated with 

 concrete, were tested for flexure, deflections, and curvature; ovaling was also measured. 

 Moment-curvature and ovaling-curvature relationships were determined from the tests, and 

 analytical values of these relationships were computed, using a strain energy method, and 

 compared with the experimental results. The effect of ovaling on the moment capacity of 

 pipe sections was determined for both the experimental and analytical results.
