Global dynamic analysis is performed to assess the dynamic response of varying offshore marine systems using world leading package Orcaflex.
SeaThor engineers have extensive experience within the subsea oil and gas and renewable offshore industries which has been developed and refined through working on a variety of dynamic analysis projects and activities throughout the years.
SeaThor can perform electromagnetic analysis of subsea cables and umbilicals, typically this analysis is performed utilizing Comsol 2D functionality however more detailed 3D studies can also be performed if required.
Studies are generally performed to assess maximum magnetic flux density of a current carrying component, the studies can also be expanded to assess several current carrying components in proximity to assess electromagnetic inference and subsequent minimum required separation distances as a result.
SeaThor has performed a range of thermal analysis studies using software package Comsol Multiphysics.
Detailed 3D backgrounds are generated within the software using pre-defined geometry and material properties, electromagnetic modules are fully coupled with fluid flow and heat transfer modules within the software to generate a representative temperature profile throughout the system. Assessments are typically performed to verify:
DNV Helica is specialist simulation software for analysis of cables, flexible pipes and umbilicals.
The following types of analyses are considered:
It is of critical importance that stick/slip friction effects of subsea umbilical inner components (which are typically laid helically) are assessed to ensure that stress in these components is accurately predicted.
SeaThor can perform these calculations to determine the maximum stress in a particular component and thus derive component fatigue life using output from dynamic analysis and material SN data.
