Installation of Deepwater Pipelines With Sled Assemblies Using The New J-Lay System of the DCV Balder

摘要

This paper describes the most important features required forrninstalling deepwater pipelines, pipelines with in-line sledrnassemblies, PLETs, and SCRs. This includes methodologiesrnspecifically developed to suit the capabilities of DCV Balder.rnDuring the last quarter of 2002, Heerema Marine Contractorsrn(HMC) performed an extensive Trials program proving allrnpipelay methodologies and associated installation proceduresrnof the DCV Balder. This included the installation of 10 kmrn28-inch and 24-inch pipe with a Pipeline End Terminationrn(PLET) and an in-line sled assembly.rnSubsequent to successful completion of these trials, the DCVrnBalder started with installation projects which included therninstallation of in-line sled assemblies with weights up to 136rnmT.
