Know the survey.
Knowledge
The method, not the marketing.
Practical, source-verified guidance for marine and cargo surveyors — written so it holds up when the figure is disputed.
Draft Survey
Reading draft marks, density and trim corrections, deductibles and the final cargo calculation.
Bunker Survey
Soundings and ullages, temperature and density, volume correction and quantity determination.
Cargo Survey
Pre-loading and pre-discharge inspection, hold and hatch condition, cargo care and documentation.
Sampling
Representative sampling, sample identification, sealing, custody and laboratory submission.
Read the method.

Why the source matters.
Every statement is ranked by the authority it rests on. Forums and social media are used to find topics — never to settle a point of fact.

From a reader
The library saves me a lot of time when I need to check a standard, procedure, or reference during a survey. Instead of searching through different websites and documents, I can usually find what I need in one place and get back to the job.

Run the survey itself
When it is time to measure and report, MarineSurvey.Online does the arithmetic.
What SurveyEra is.
An independent publication covering marine surveying method, cargo inspection and marine claims. Every technical statement is traced to the instrument, standard or recognised practice it comes from, and the source is listed on the page.
SurveyEra explains how a survey is done and why. When you need to actually conduct and document one, MarineSurvey.Online is the digital workflow built for it.
The software behind SurveyEra
Stop doing the arithmetic on a clipboard.
Software built for marine surveyors: guided measurement entry, the calculations done for you, and a documented report at the end — on board, offline, on any device.
- Draft Survey Enter the six drafts and the soundings; the module applies the draft mark corrections, the quarter mean, both trim corrections and the density correction, and produces the survey report.
- Bunker Survey Soundings or ullages, temperature and density in, corrected volume and quantity out — with the tank tables, the trim and list corrections and the VCF handled for you.
- Fleet Manager Keep vessel particulars, hydrostatic data and tank tables in one place, so the next survey on the same ship starts with everything already loaded.
