Lightship Survey & Weight Estimation

Onboard lightship weight surveys and detailed weight estimation reports for stability documentation.

Overview

A reliable lightship weight is the foundation of every stability calculation. Our surveyors conduct on-board lightship surveys — verifying deadweight items, sounding tanks, and reconciling actual mass distribution against design records — to produce a defensible lightship statement.

For projects at the design stage, we build detailed weight estimation reports from first principles, aggregating structural, outfit, machinery and margin weights to give the design team a reliable KG and displacement forecast.
