Quantapoint’s Digital Facility has been applied to improve and enhance the management and maintenance of asset information and workflows which improve the overall asset performance by project and over its life. Access to capital information in 3D across the organization improves communication and decision making.
Quantapoint’s core purpose is to help facility owners and operators reduce dimensional uncertainty. Processes that suffer from uncertainty include:
Front End Engineering and Design
Using a Digital Facility early in the project planning stage enables more efficient process optimization, plot plan development, and improved efficiency for engineering tasks. Having a digital model of an existing unit can provide guidance for reusing the unit in new facility designs or can provide background information to guide revamp or debottlenecking efforts in most CAD environments.
Capital Expansion Projects
Capital projects tend to introduce a large amount of new equipment and piping into the existing plant, so accurately locating connection points and performing clash detection of new items against the backdrop of the current facility provides the largest efficiency drivers. Engineering designs can be executed with sufficient certainty to eliminate field fit up welds from the normal design process.
There are unique challenges in creating a Digital Facility on a floating structure. Quantapoint has developed specialized technology and work processes which enable reliable and accurate laser scanning on moving platforms (such as FPSO’s). This technology compensates for vessel movement, the lack of a fixed gravity reference, and improves the speed of data collection. Through the application of the Digital Facility work process, the laser data is integrated with the Cad model to enable interactive design, clash elimination and construction planning. Use of Digital Facility serves to validate the design integrity, eliminate clashing, plan construction and verify fabrication in a complex, congested moving structure.
As systems such as FPSO’s, FSO’s are continually upgraded to handle larger volumes, the Digital Facility offers a unique way to capture as-build documentation while the vessel is at work.
Construction Planning and Visualization
The Digital Facility and associated work processes can provide fabrication and construction activities with tools and information to reduce rework, improve communications, and cut schedules.
Fabrication verification services using the Digital Facility routinely improve construction schedules and reduce wasted capital by finding errors in spool and vessel fabrication long before construction begins. Construction planning benefits through precise location of cut lines, visualization of spool sequencing and lift planning, scaffold planning, and assembly simulations.
As additional reserves are found surrounding existing producing fields and secondary production methods are implemented in declining fields, the resulting increases in production requires upgrades to existing infrastructure. Much of the existing infrastructure is often old and largely undocumented, so the speed with which as-build documentation can be created and engineering and design processes initiated creates value.
A Digital Facility can be quickly created for an area of damage on a production facility in the field from which construction drawings can be developed. Upon fabrication of new spools, the fidelity of these replacement spools may be electronically checked against the drawings to ensure they are fabricated correctly; eliminating rework and ensuring rapid fit up in the field. Further, visual inspection and measurement of piping, equipment and instrumentation that may have been impacted by the accident may also be discovered and remediated. This work process has repeatedly shortened the down time of offshore installations following an emergency event.
