The Part and Stiffener Reports

The part and stiffener reports list the parts and the stiffeners of the project together with their data. In MasterShip they are presented in the MasterShip Organiser under Reports, where you can find the Part Reports, the Stiffener Reports and the Plate Reports. The preceding process step is the modeling of the parts and stiffeners, and for the plate reports the nesting and the cutting order must be done first.

In general, these reports give a clear overview of the parts and stiffeners in the project, such as the stiffeners by drawing with their profile code, length and the normal and mirrored quantities. They are the deliverables that tell the workshop and the other stakeholders what has to be made and where it belongs.

Which SHIP-commands apply?

SHIPSYNCHRONIZEPROJECTFLODERS: use this command, and then open the MasterShip Organiser and click Reports - Part Reports / Stiffener Report / Plate Reports; in this way you can get the part, stiffener and plate reports. By the way, you should finish the nesting and make the cutting order first, and then do the last step, before you can get the Plate Reports.

Export as Excel-format (not a SHIP-command, but functionality and templates): right-click on the part/stiffener report in the Organiser view and export it to Excel. Also, use the Excel templates in the Company-settings folder for a nice mark-up.

How can it be used?

1. Model verification and self-check in production design

Part lists are exported in batches from 3D models to count component quantity and section weight. By comparing with weights from basic design, engineers can quickly identify missing or duplicated parts, errors in plate thickness and profile specifications. COG data extracted from the list supports weight and gravity assessment for sections and lifting plan evaluation. Special parts including thick plates and curved components can be screened in advance to optimize manufacturability and reduce rework.

2. Plate procurement, material issuing and inventory control

Summarized part information provides the basis for plate requisition. Purchasing departments determine plate ordering specifications and tonnage. Warehouses issue plate by block according to the list to control material consumption and loss. Plate cost and material utilization rate can be calculated based on net weight plus cutting allowance.

3. Nesting and NC cutting (key application)

Nesting engineers import part lists to nest components of identical material and thickness, generating nesting drawings and NC cutting codes. The list supplies developed contours, bevel directions and hole information to guarantee complete part data. After nesting, nesting plate numbers are written back to the part list to establish one-to-one correspondence between parts and nesting plates. Cutting workshops identify parts by unique numbers after blanking for subsequent sorting.

4. Part sorting, fabrication and semi-finished product management

After cutting, workshops check quantity, thickness and material against the part list to detect missing or faulty parts at an early stage. Components are classified by machining processes such as plate cutting, bending, profile forming and edge preparation and allocated to corresponding workstations. The list serves as a semi-finished tracking table with status marks including blanked, machined, assembled or missing to solve difficulties in part searching during block assembly.

5. Section assembly and erection

Assembly crews verify structural components required for each section with the support of part lists and assembly drawings for sub-assembly and section erection. Weight and COG data are used for lifting tool selection and safety verification. Allowance information guides on-site trimming to ensure dimensional accuracy of sections.

6. Weight & COG calculation and survey inspection

Part weight and COG coordinates are aggregated to prepare section and grand section weight reports submitted to shipowners and surveyors. The part list is attached as supporting documentation to prove that weight data originates from production design models rather than empirical estimation.

7. Man-hour estimation, production planning and cost control

Machining man-hours are estimated according to part types to arrange workshop schedules. Scrapped parts are recorded to calculate scrap rate and improve subsequent nesting and design. The list also provides quantity basis for fabrication completion settlement.

As a data carrier transferring 3D production design models into physical ship components, the part list runs through the whole hull construction process. It supports upstream model weight checking, midstream steel requisition, nesting and NC cutting, as well as downstream part tracking, section assembly, weight survey and cost accounting. The part and stiffener reports are shared with stakeholders, or used in the workshop.  Exporting the reports to Excel with the Company-settings templates gives a nice mark-up that can be distributed and reviewed.
