DNV GL advances 3D simulation technology for marine operations

Sesam Marine software

Marine operations - such as transportation, installation and lifting of fixed and floating structures and subsea equipment - are becoming increasingly challenging as operators move to harsher climates and deeper waters. DNV GL is launching Sesam Marine, a groundbreaking software solution that keeps pace with the increasing complexity of marine operations with 3D simulation and visualization.

Sesam Marine for complex analysis

“This is the first time that complex analyses of marine operations can be visually experienced through simulation using Sesam Marine software. The benefits are crucial for successful completion of offshore installations,” says Are Føllesdal Tjønn, DNV GL.

With Sesam Marine software it is possible to manage risk through calculation and visualisation of marine operations, taking into account environmental conditions and structural components. Realistic and rigorous testing and evaluation of operations is possible using environmental conditions and dynamic positioning as parameters. The simulations can be used during real-time execution of operations, including installation of subsea structure such as templates, flexible risers, umbilicals and pipelines. The coupled and multi-body analysis is performed in time domain.

Sesam Marine can be used in many facets of marine operations, including lifting and installation of topsides, modules and subsea structure, floatover installation and removal of topsides and offloading tankers in tandem or side-by-side. The ability to quickly visualise the operations in 3D and run multiple ‘what-if’ scenarios immediately showing the results of all known factors reduces risk of offshore installations significantly.

“Seeing the operation through realistic computer simulation offers unequalled decision support,” says Stian Barkbu, DNV GL. “Technicians will see ahead of time how the components will react to the acting forces, what motion will be incurred, for example swing movements of equipment or the heeling force on a vessel or offshore structure. Fast analysis capabilities are now integrated with a graphic front-end that provides immediate visual feedback,” he says.

About Sesam Marine software

The Sesam Marine software package makes it possible to manage risk during marine operations by prior calculations and 3D visualisation of for example transportation, installation and lifting of fixed and floating structures and installation of subsea equipment, taking into account environmental conditions and structural components. Sesam Marine software also provides decision support during the actual operation.
