Survey/ 3 D scanning/Data Analysis
FEASIBILITY
- FUNNEL SPATIAL CHECK
- BACK PRESSURE CHECK
- TYPE OF SCRUBBER-INLINE OR U
- NO. OF SCRUBBERS
- SEA CHEST CAPACITY CHECK
- HYBRID OR OPEN LOOP WITH HYBRID READY
- BOILER ??
- NEUTRALISATION AGENT
- FLOW RATE-DEPENDENT ON OEM
- PAINT COMPATIBILITY
FEASIBILITY
OPTION 1: DESK BASED – COST EFFECTIVE
– FAST EXECUTION
– ONLY BASIC LEVEL STUDY
OPTION 2: 3-D SCAN
BASED– VERY ACCURATE
– COMPLETE SPATIAL FEASIBILITY
– DETAILED STUDY
FEASIBILITY
3 D SCAN– BEST WAY TO GET AS BUILT DATA
(CORRECT AND ACCURATE)
– 2-3 DAYS OF SCANNING + 1-2 DAYS OF DATA PROCESSING
– SAME SCAN CAN BE USED FOR FEASIBILITY STAGE AND DESIGN STAGE
– VIRTUAL REALITY POSSIBILITIES
CLASS DWGS

• Misc. SLDsElectrical
WORKSHOP DWGS
• Production Design in 3-D environment
• Pre-fab of pipe spools
• Avoid hot work on board
• Production Design outputs:– 3-D Pipe route– Iso-metric and spool drawings.– Pipes installation drawings– Cable duct/HVAC Duct routing– Structural Fabrication Drawing
PROJECT MNGMT.
• Class Approvals– Approvals for Retrofit Drawings– Coordination for Class survey onboard
• Workshop Co-ordination– Technical Specification for retrofit– Job work order & Workshop Selection
• Supervision– Quality inspections
(critical for in-situ fabrication)– Workshop inspections for pre-fab
pipes
