Structural Engineering Projects

We have been mainly involved in Oil Industry Projects, and have designed Lattice structures, Cantilevers, Towers and Cranes for rough deepsea conditions. Therefore we are perfectly capable of providing structural engineering design for other ordinary onshore structures with special conditions, including loadings as – earthquake, which is very similar to offshore rig motion loading.

Tubular Feeding Machine and Support Structures
The Riser Tubular Feeding Machine (TFM) is handling Risers and Slipjoint from a horizontal position and into vertical position in the center well. The pipes are supported by the trolley and front cradle, when horizontal. The pipes are lifted by the DDM and supported by the trolley only when inclined. The trolley is supported by the Skate. The Skate is moving on a rail which is supported by the support structures. The structural engineering design of each main part have been prepared in one consistent document.
