Our developed Digital Profile Mapping (DPM) is used to analyze turbine in-process important activities with real-time guided results to make better and faster decisions. DPM saves productive days of total schedule of the turbine overhauling and at the same time accurate results. Also, conventional methods like blue ink check, frequent bolt tightening and loosening, unguided scrapping, pot leveling etc. are eliminated and frequent handling of the heavy components is highly reduced.

TURBINE ALIGNMENT & SETTING

Rotor Setup & alignments by providing shim adding & removing

TG DECK MONITORING

Deck periodical monitoring & deck behaviour analysis support

CATENARY MEASUREMENT READINGS

Pot Level, Pedestal Elevation checks & Periodical Monitoring

By the Catenary Mapping, the design deviations can be analyzed and problems like Shaft or bearing Vibrations or temperature rise in Babbitt metal can be controlled. We also know that during the first few years of operations of the unit, the possibility of the disturbance of catenary is much more due to the settlement of the foundation frame. So to achieve the best alignment of rotors and loading on the bearings, Catenary becomes a very important factor.
Catenary Measurement by our procedure takes approx. 2-3 hours and can be squeezed into any available time slot within 24 hours. During this activity, there is NO WAITING TIME required as in conventional procedures due to controlled temperature, environment, air pressure stability

COUPLING FACE RUNOUT & CORRECTIONS

Convex or concave behaviour-digital face matching-guided scrapping with continuous laser reading of coupling

ROTORS AXIAL RUNOUT

We provide the best quality 3D Laser Scanning of old & congested plants, structure, piping &supports for As-Built primitive modeling& GA layouts drawings. By incorporating specifications and P&ID details the ISO metric drawing with BOM can be extracted or delivered. This service will be a good help in RENOVATION, REVAMPING, CAPACITY ENHANCEMENT DESIGN STUDY, MODERNIZATION & EQUIPMENT SHIFTING & REPLACEMENTS.

3D MAPPING & AS-IS SPECIAL ASSISTANCE

To support New Installations and Compatability at with existing areas.

• FINALIZING LAYOUT FOR FGD INSTALLATION
SixD is providing specialized assistance by 3D Mapping for As-is & As-Built Details which supports in finalize the layout of FGD and surrounding existing area. Our 3D model created by this methodology is within ±2mm to ±3mm accuracy. The provided model will be used for extracting As-Built Layout drawings to get help in simulations, changes/modifications for fitting FGD plant in existing plant defined area. All the required layout 2D drawings can be extracted from this model as- and- when required for review and finalizing the layout of FGD plant and the existing plant facilities.
