3.7 3D Modelling

Synterra offers 3D modelling services using industry tools such as PRO/E and SolidWorks. Design concepts will turn into life by modelling the basic geometry in SolidWorks. The ability to generate quick concept models allows for exploration of more possibilities in far greater depth.

With extensive subsea equipment database, ROV information and experienced engineers, Synterra also provides the ROV access study. The study will be adhered to given specifications, relevant industry Codes and Standards, and in general an adoption of a “best practice” approach to design; ideally resulting in structures/equipment which are fit for purpose with particular regards to installation, operation, contingency and IMR activities for its given design life. Virtual ROV studies and, in turn System Integration Testing (SIT), serve to identify and address any potential operational issues arising from the design phase whilst the structure/equipment can still be relatively easily altered, i.e. first in a virtual environment and second in a Fabrication Yard environment; in an ultimate effort to optimise offshore operations.

The structures, equipment, Work Class ROV (WROV) and ROV tooling have been modelled in the 3D modelling. The WROV is based upon a typical model with envelope dimensions either in excess, or at the upper range, of those provided as guidance within ISO 13628-8 Annex A – “Summary of work class ROV specifications”. The virtual WROV is outfitted with industry standard of five and seven function manipulators on left-hand and right-hand side of the vehicle respectively. These selected manipulator operating envelopes are aligned with the informative envelopes as per ISO 13628-8 Annex C – “Manipulator Operating Envelopes”.
