Your rig file holds the stack
The BOP stack and the control unit from your 16D calculation are already in the rig file.
Solutions · One rig model, every standard
One rig model,
every standard.
Start with the BOP control system. Add the riser, the drill string, the casing and the drilling line. They all share the same rig model and engine, and every module is checked against its standard's own worked examples.
Already using the 16D check? Adding another module takes minutes, not a new project.

16D BOP calculation
Surface BOP control systems to API Spec 16D, Annex D: main accumulator unit, dedicated shear, diverter and pilot circuits, pumps and reservoir, real-gas nitrogen, and a print-ready report.

The product line
Layer by layer, from the BOP down.
Every module reads the same rig file, runs on the same engine, and ships with its standard's published worked examples reproduced.
BOP and well control
The control system that closes the well, and the tests that prove it.

Riser
What holds the riser up, and how much is left.
Mast and hoisting
The line that lifts everything.
Wellbore
The pipe in the hole and the casing around it.
After the rig leaves
The well keeps reporting through its annuli.
One rig file
Enter the rig once.
Most rig calculations use the same equipment data. RigLogicOS keeps it in one rig file; each module reads what is already there and asks only for what is new.
Add another module
It reuses the stack weights, pressures and volumes, and asks only for what's new: riser joints and tensioners, drill string, casing program.
Same screens, same report
Same sign-in. Your team already knows how to use it, and reviewers already know how to read it.

Why engineers trust the numbers
Checked, sourced, and shown.
- Checked against the standard's own worked examplesEvery module ships with the published examples reproduced and the tolerance it meets.
- Every factor has a sourceTagged with where it comes from: the API standard, engineering practice, your project input, or physics.
- No hidden defaultsProject data has to be entered. Every default still in use is listed in the report.
- Reference physicsNitrogen from the Span et al. (2000) reference equation of state; ideal gas shown only for comparison.
- Charts drawn from the calculationEvery chart comes from the same calculation as the reported numbers.
- Each module names its editionYour project stays on the edition your contract or regulator references until you move it.
