How it works
- 1Read drafts
Take initial and final draft readings on all sides, with water density samples where relevant.
- 2Collect data
Gather hydrostatic particulars, ballast condition and any other data needed for calculation.
- 3Calculate
Compute cargo quantity using the draft survey method and cross-check with shore figures where available.
- 4Report results
Deliver a calculation report with readings, assumptions and the resulting quantity.
Frequently asked questions
When is a draft survey used?
Typically for bulk cargoes where shore scales are unavailable or where an independent quantity check is requested at load or discharge.
What inputs does the calculation need?
Draft readings, hydrostatic or stability data, ballast quantity, water density and vessel particulars.
Findings are documented with clear observations, supporting evidence and practical follow-up recommendations where appropriate. The final report is structured for commercial and technical review, and attendance timing, access and the agreed scope are confirmed before work begins.
