P&ID Field verification and Redraw

MSB&A design and drafting has many years experience in the walkdown and redraw of piping and instrument diagrams for several major refineries. MSB&A has been responsible for the complete walkdown and CAD redraw of several units, whose documentation was either incomplete or nonexistent. MSB&A was instrumental in providing accurate field representation and critical data for regulatory requirements and unit maintenance.

Product Assurance/ Contingency System

MSB&A Designers and Drafters Work with Product Assurance/Operations to isolate different product systems and product flow within a refinery, including walkdowns and field sketching. These sketches are redrawn in CAD creating plan drawings and isometric details for applicable reference for Operations and Maintenance.

EMPROV Drawings

MSB&A was entrusted with the task of providing drawings using the existing P&Ids as a reference attachment, which highlighted each system throughout a unit with a unique color. The critical requirement was that the existing P&Ids could not be altered in any way. In the beginning stages of this project, MSB&A was tasked with the responsibility of proving that the desired outcome could be achieved without resulting in a change to the system P&Ids. MSB&A achieved this goal and to date several units have been completed, with several more anticipated in the near future.

Corrosion Drawings

The corrosion drawings are flow diagrams created in color, with assigned colors to each type of material used in a process system. One look at the corrosion drawing and all parts of the process can quickly be analyzed by material and main process flow.

Automated Field Terminal Assembly and Marshaling Rack Drawings

The MSB&A drafting group developed a method of linking the Loop Wiring Database, which was recovered from a console download from the TDC-2000 equipment being replaced and then modified for use by the instrumentation designers, to the CAD software. This allowed the 150 field terminal assembly and marshaling rack drawings to be generated automatically. This prevented a multitude of keystroke errors associated with the manual entry of loop wiring data for 1300 points across eight termination points each.

Laser Imaging Distance and Ranging (L.I.D.A.R.)

MSB&A provides the ability to create accurate as-built 3D documentation of existing structures, in a safe, cost effective manner. Utilizing the Cyrax 2400 laser imaging system, it can be pointed at high structures from large distances, making it unnecessary to build scaffolding for access and risky manual measurement. Once the scanner captures a location, data representing the location become instantly 3D-viewable with full rotation, fly-around, pan and zoom capabilities. This scanned information can then be modeled into a CAD model and dimensioned. Future expansions can be added to the existing model with various piping software packages, and full construction isometrics and plan views can be created for the project. New construction can then be checked against existing equipment and corrections made before any actual work has begun.
