HES designed and coordinated the conceptual design of a subsea pre-piling template to monitor and correct pile inclination during offshore installation. HES proposed and performed a dynamic over-turning moment analysis that incorporates template-soil and pile-soil interaction.
The environmental loading was analyzed with Orcaflex. The analysis resulted in a considerable weight saving without compromising on offshore workability.
HES' analysis justified building a lighter and therefore lower-cost template, which was easier to handle offshore. As part of the scope HES designed the hydraulic leveling system. Our partners involved this project were Tillen and PT Structural.
