FEM

Structural Analysis is the detailed visualisation of where structures might bend or twist. It is vastly cheaper to test a structure on paper than in reality, and the analysis enables designs to be constructed and optimised before being manufactured. Based on the rules and regulations of all major classification societies covering all types of vessels and marine operations, OSK-Offshore is able to carry out a wide range of calculations to determine the strength of structures or the reinforcements needed. 

Using RFEM, we provide quick and easy modeling, structural analyses as wells as designs of 2D and 3D models.

Using RSTAB, we can swiftly perform 3D structural frame analyses as well as calculate internal forces, deformations and support reactions.

Using 3D design software ANSYS, engineering simulations can be performed, cutting costs on real-life testing. 

Our services include:

Longitudinal strength
The hull needs to be able to contain the cargo safely even in the worst weather conditions. With a structural analysis, it is possible to analyse and calculate the correct amount of strengthening required for the hull.

FE models
OSK-Offshore is able to calculate both local and global Finite Element models. An FE model is made in order to optimise and design structures with the least amount of steel and welding.

Buckling
This refers to the structure becoming unstable prior to the actual material failure. The analysis is carried out with Finite Element Modelling or with offset in the rules of the classification societies.

Lifting appliances
With offset in the rules of the classification societies, OSK-Offshore can calculate the lifting capacity and outreach of a crane, as well as find the most suitable position on the vessel to support the crane.

Primary structures
These are the framework of the vessel, and often Finite Element Modelling is necessary to determine the complex distribution of significant loads into the structure of the vessel.

Conversions
OSK-Offshore has many years’ experience in designing both major and minor conversions, ranging from an overall lengthening of the hull to building in additional features such as a hoistable car deck.

Seafastening
This includes local reinforcements, cradles and grillages for transportation of project cargo, e.g. components for wind turbines at sea.

Damage investigation and repair specification
If a vessel has been damaged or is experiencing structural failures, OSK-Offshore can investigate the source of the failure and prepare a specification for the repairs to rectify the damaged structure and prevent the reoccurrence of structural failures.
