Sub-Sea System Projects

We have carried out numbers of Sub-Sea Projects using OrcaFlex & MOSES software's for Indian and Middle East clients as below:

IOC Paradip SPM

The objectives of the study were to model the Paradip SPM system with CALM (Catenary Anchor Leg Mooring) arrangement in OrcaFlex, matching the SBM model as closely as possible and then assess the extreme response of the system under various load cases on the submarine hoses, the floating hoses and the mooring hawsers. The results and the operating conditions were compared with the reports provided by SBM. The work was completed and suggestions were made for improvements to the system based on the investigation and identification of the causes of failures of the subsea hoses and mooring hawser.

HMEL Mundra SPM

Scope of work was to carry out independent Sub Sea hose analysis of the Mundra SPM due to failure of the recently installed Sub Sea hoses. The work was completed and solution for installation of new Sub Sea hoses provided to the owners.

Mooring System for SESA GOA

Scope of work was to carry out design analysis of four sets /configuration of mooring buoy system to include the anchors, buoys, chain, connective jewellery and hawsers to the standards set by ABS Rules for Building and Classing Single Point Mooring. OrcaFlex software was used.

Single Point Mooring Verification for ESSAR at Vadinar

Scope of work was to carry out independent Sub Sea hose analysis of the ESSAR Single Point Mooring installed at Vadinar to transfer fluids of different density using the as installed Subsea hoses configuration. OrcaFlex software was used.

Riser & Mooring Analysis of Drillship (ONGC)

Aryatech is having expertise in the Riser and Mooring analysis using OrcaFlex software. We completed Riser and Mooring analysis for ONGC drillship at water depth of 265m along the Eastern Coast of India. Analysis is done following the global standards API RP 16Q and API RP 2SK.

Scope of the work included checking the feasibility of existing riser capability of ONGC for the said location and designing a feasible mooring configuration. A workable mooring pattern was designed considering the environmental loads and the operational constraints of the drillship. Damage mooring analysis was done to check for the critical cases when one or more mooring lines are broken.

Riser & Pipeline Installation for Union Dredgers

Scope & Objective-24? existing pipeline is to be replaced by HDPE pipeline, to analyze the various stages of Installation for critical parameters involved and simulating the real time environment for the pipeline installation.

Analysis-Re-modelled 690m existing subsea pipeline sections to satisfy the new installation methodology acquired by the client and carried out the installation analysis and abandonment & recovery analysis using OrcaFlex to sustain the environmental conditions of the location Halul island, Qatar.

Riser Analysis for Drillship (ABAN Offshore)

Riser analysis for ABAN Offshore Drillship at water depth of 625m and 1500mwas carried out using OrcaFlex Software. Analysis is done following the global standards API RP 16Q.

Scope of the work included checking the feasibility of existing riser capability of the drill ship for the said location. A workable Riser Stack up was designed considering the environmental loads and the operational constraints of the drillship.
