Abstract

1536896 Laying pipelines COMPAGNIE GENERALE POUR LES DEVELOPPEMENTS OPERATIONNELS DES RICHESSES SOUS-MARINE C G DORIS 26 May 1976 [30 May 1975 13 May 1976] 21748/76 Heading F2P In laying a pipeline 1 in a body of water 2 the pipeline 1 is enclosed over its whole length within a continuous ballast tube 4 and as the assembly of the pipeline and ballast tube proceeds the intermediate space 5 between the pipeline and the ballast tube is filled with a liquid less dense than water, such as a light hydrocarbon, to give the assembly of pipeline and tube a positive buoyancy while the assembly is being laid and replacing the said liquid with a medium of sufficient density, such as soft water or a grouting having a base of an hydraulic or hydrocarbon binder, to cause the assembly to rest on the bed 2a.
