ORCAFLEX FLEXIBLE RISER SOFTWARE

It is believed that with real time inputs, the software can better assist clients to monitor the pipe fatigue performance and other related riser responses. This paper summarizes the development of the pipe monitoring system. Other parameters like riser real time extreme response or statistical results can also be checked in the software. Depending on clientsвЂ™ needs, multiple fatigue hot spots like top end fitting, bend stiffener region or touch down zone can be monitored at the same time. The software can be customized towards different platforms and pipe systems, as well as input data types.

Developed in Python, the software utilizes an OrcaFlex API and a local analysis algorithm in the background. The software is based on product design tools which are calibrated and independently validated with over 30 years installed operational experience. With real time data, a more accurate estimation on fatigue performance of riser can be achieved, which could enable the service life extension without compromising the design safety factors.ДЄ special software tool has been developed to calculate the real time fatigue damage of flexible tensile wires.

This powerful course is mostly used as an Offshore & Subsea / Naval engineering software for developing professional subsea pipe design and analysis, floating platform hydrodynamics, mooring lines and riser static and dynamic analysis, among other very important offshore marine. Compared to the typical input data/assumptions made in predictive analysis, these records are more precisely and directly related to the actual fatigue damage accumulation. OrcaFlex is the worldвЂ™s leading package developed by Orcina for the dynamic analysis of offshore marine systems. Furthermore, pipe internal operating conditions like pressure and temperature are usually recorded onboard. Many platforms or vessels already have real time monitoring of motions in multiple degrees of freedom and wave/current data. In combination, these inheriated conservatism permits the feasibility of service life extension of the flexible riser systems. In addition to the conservatism inherited in the product design methodology and API safety factor 10 for fatigue estimation, the input data may also contain some additional conservatism compared to actual operational conditions as these were estimated/projected from limited time-span of observations or predicted purely from numerical modelling. Metocean data, riser properties, vessel or platform RAO data are typical inputs for the fatigue analysis. To estimate the fatigue damage, global and local analyses are performed inhouse with inputs from operators. Fatigue life of flexible risers is a critical design factor in offshore riser system design.
