Project

This RUB 16 billion ice-resistant offshore platform is one of the largest and, due to harsh conditions, most complex projects in the Caspian Sea. In the coldest months, the summit temperature averages -20° C (-4° F) and can drop as low as -36° C (-32.8° F). The goal of CNGS Engineering was to design a platform that can tolerate this environment, bear the very heavy platform weight, and withstand extreme ice, wind, and wave loading.

Solution

Bentley products were selected to perform the design and check load tolerances. SACS was used to identify loads from ice, wind, and waves during construction, transportation, installation, and operation. Other design considerations included the layout of treatment facilities, equipment, and piping. Support units were designed using 3D modeling to sustain the platform’s massive weight as well as prevent ice-load damage. The jacket weight was optimized to decrease the structure’s overall weight.

Outcome

Using Bentley software, CNGS Engineering was able to overcome the challenges presented by the extreme conditions of the Caspian Sea and deliver a structure of optimal weight and durability. This was accomplished more successfully than could have been achieved using traditional design methods and products. Bentley products ultimately allowed CNGS Engineering to minimize the cost of the engineering design work.

Software

CNGS Engineering led a group of eight subcontractors who used ProjectWise to eliminate file-transfer difficulties. Other software being used on the project included SACS, AutoPIPE, OpenPlant PID, MicroStation, and Promis.e.
