Construction Solutions services
In addition to our industry leading Construction Solutions software, we offer a range of services designed to compliment and further our software offering.
Digital systemisation / subsystemisation
Systemisation and subsystemisation are time consuming, often resulting in unpopulated completions systems until well into the construction phase. This significantly impacts both the ability to “plan with the end in mind” during engineering, and to define the optimum path of construction. Tag numbering usually contains the system code, which is created by engineering. However, experience has shown that in 15%-20% of cases, the tags end up in different systems to the system code contained in the tag number.
The asset55 approach
Our digital process is linked to the 3D model, which accelerates the systemisation process based on engineering deliverables. This process provides visual validation of system limits and supports the optimisation of the subsystemisation process.
On a major project, systemisation and subsystemisation can be achieved in as little as 3 months. This enables a digital offtake from the model to populate the completions system. It is acknowledged that engineering is not complete at this time, but the process has been proven to be more than 90% accurate. This is achieved in a fraction of the time and cost of the traditional process. Identifying discrepancies between system allocation and tag numbers can support the updating of tag codes before they are issued to a construction contractor. This also improves the intelligence in the model for the digital twin. Visual systemisation and subsystemisation enables the path of construction to be optimised with “plan with the end in mind”.
Digital test pack development
Traditionally, test pack development is the responsibility of the construction contractor. This relies on subsystemisation being complete, typically meaning all test packs are not developed until the construction is more than 30% complete. The process starts with marking up P&IDs and cross referencing these with the line list to confirm test pressures, pipe specs, test mediums, etc. This process is extremely time consuming.
Developing test packs late also impacts the ability to “plan with the end in mind”. Test pack transition is a critical step in enabling the completions process in opening painting, heat trace, and insulation, as well as clearing the path for E&I disciplines.
The asset55 Approach
Digitising and automating the process of creating test packs linked to the 3D model allows for both visual confirmation and improvements. By linking the line list to the model via our model enrichment process, we can apply artificial intelligence to segregate the piping into potential test packs.
Using the 3D model helps visualise constructibility, aiding in the breaking down of test packs further for optimisation. Once completed, all the lines are exported from the model with their test pack reference and attributes for heat trace and insulation requirements.
This process can begin after the 60% model review and be completed in parallel to the digital systemisation process.
Test packs are developed digitally during engineering to support the optimisation of heat trace circuits. On a large scale project, this can be completed in approximately 8 weeks, and at a fraction of the cost of traditional approaches. With provisional test packs understood, this data can be used in support of advanced work packaging principles, execution planning, and resource planning.
Advanced work packaging
The advanced work packaging process has been steadily gaining momentum within the oil & gas industry. Its primary purpose is to align engineering and procurement deliverables to path of construction. This releases complete and available work scopes to the field, improving field productivity and time on tools. Without readily available completions data, the path of construction fails to consider the path of completion. Projects are broken down into construction work areas, which are subsequently broken down further into construction work packages. These are used by workface planners to develop installation work packages. This approach is problematic as the construction work packages become too large, and do not provide enough focus for engineering to deliver against. Furthermore, this approach is heavily reliant upon the skill of the workface planners to create effective installation work packages.
The asset55 Approach
Our approach is to improve two critical areas of the advanced work packaging process. Firstly, we include the completions data into the optimisation of the path of construction. Secondly, we breakdown construction work packages in a consistent manner, which improves engineering focus and the optimisation of installation work packages. Using our digital systemisation and test pack development processes, completions data is made available when the path of construction is being developed. Construction work packages are broken down based on primary structural steel into fabrication / erection blocks, which are typically 90% smaller than a traditional construction work packages. We then extract the tags using our box offtake process, and categorise them by discipline into 3 categories, P1, P2 and P3:
- P1 tags reside completely inside the volume and should be installed at outfitting
- P2 tags cross the block volume on a horizontal and should be installed when 2 blocks come together
- P3 tags cross the block volume on the vertical and should be installed once the block above is erected
Categorising all tags by block and install priority makes the installation work package planning process both simpler and more consistent. It also narrows down the engineering delivery priorities by block, which reduces the likelihood of late changes.
When overlaying completions data, completions activities are automated by highlighting opportunity release scopes when blocks come together, test packs for walkdown, cables to pull, etc. The path of construction can be optimised by simply re-sequencing block delivery.
- Optimised path of construction inclusive of path of completion
- Consistent and more effective advanced work packaging approach
- Automated completions planning
- Plans based on block movements, which are easy to understand
- All available visually for collaboration and communication
- Reduced reliance on skill of workface planner
- Lower planning costs
- Model Reviews
We can support our clients in improving the accuracy of the 60% and 90% model reviews. Our approach is to take all engineering deliverables (data files) and cross-reference these with the 3D model to identify gaps, discrepancies, and tag number mismatches to improve the accuracy of the 3D model prior to each review. Typical data files include:
- Line lists
- Equipment lists
- Valve registers
- Cable schedules
- Pipe supports
