Tie-in Spool Design Automation

Atteris’ in-house software CONNECT has been designed to optimise cost and timeline, during the engineering phase as well as during fabrication and installation.

The CONNECT software leverages over 20 years of knowledge and expertise in the design and installation of rigid tie-in spools around the world.

CONNECT uses automation to minimise the time and effort required to assess the code compliance of specified spool configurations, and to automatically identify the shortest possible spool within specified acceptance criteria.

Practical Probabilistic Design and Optimisation to Reduce Spool Sizes

Deployed successfully on FEED projects for Australian operators, Atteris CONNECT has helped clients achieve substantial reductions in the spool sizes using automated probabilistic and optimisation algorithms.

By analytically removing conservatisms inherent in the design assumptions, CONNECT is able to leverage a risk-based design approach to minimise the size of rigid spools, allowing clients to:

Improve safety and spools handling
Reduce installation vessel requirements
Reduce fabrication costs

For more information, read our AOG conference paper.

CONNECT Features and Capabilities

Atteris CONNECT has been developed in-house by tie-in spools engineers specifically for the design and optimisation of rigid tie-in spools. Features include:

Automatically generation of critical spool configurations based on target box tolerances
Assessment in accordance with DNVGL-ST-F101, ASME B31.4/B31.8 and other common design codes
Assessments using Carbon steel (with and without internal clad) and Duplex Stainless Steels consider Hydrogen Induced Stress Cracking (HISC)
Pre-formatted summary tables for commonly reported results to expedite the generation of reports
Solver using industry accepted AutoPIPE FEA software
Response Surface methodology and Monte Carlo Simulations for rapid probabilistic risk-based design assessments
