A draft survey at Libreville turns the ship into the scale: our draft surveyors read her before cargo moves and after it stops, apply the vessel’s own hydrostatic data, and certify the weight with the working attached, the attendance confirmed in writing before it starts.

Six readings, honestly taken, or a figure that drifts. A reading taken from one side, in swell, or by an interested party is a number waiting to be challenged. All marks, both sides, corrected from the ship’s own tables, is a number that closes files.
The density sample decides real money. A density sample taken at the surface, or hours from the reading, quietly moves the cargo figure by truckloads. Ours is drawn at depth, at reading time, without exception.
Libreville settles manganese on this number. The bulk trades over Libreville are bought and sold by weight. The party holding the independent draft figure collects on it; the party without one settles on somebody else’s.
One call at a port often opens several files — the cargo, the fuel, the vessel itself — and our team holds them all. Step into the unit your matter needs; one instruction line carries the rest.
Our highly trained draft surveyors carry out all types of draft surveys, draught surveys, and bulk weight determinations at Libreville Port, Gabon, through our own local surveyors at the port, with every attendance confirmed in writing before work begins: initial and final drafts for discharge and loading, intermediate drafts where parcels split, lightering and barge drafts, and joint surveys where both sides sign one figure. The port’s bulk trades, manganese, settle on these numbers, and the report reads the same as the file from any port we serve. Also see: cargo surveyors in Libreville.
A defensible draft survey at Libreville is method, not opinion: all marks read from the water on both sides, at the start and the end of the operation; dock water density sampled at depth at the time of reading; trim, deflection, and density corrections applied from the ship’s approved tables; ballast, fresh water, and consumables sounded and deducted. The certificate carries the entire working, so an adjuster, a trader, or a tribunal can follow every line to the final tonnes.
A shortage at Libreville is only as strong as its paper. Our surveyors set the draft figure against the weighbridge tickets, the silo meters, and the bill of lading, log every stoppage and every squall during the operation, and issue the letter of protest while the vessel is still alongside, so the claim starts with the evidence already secured rather than reconstructed.
Traders & receivers. The independent weight is the invoice’s defense: what was paid for is what was measured.
Shippers & terminals. A joint figure signed at the ship protects the honest operator from the other side’s arithmetic.
Cargo insurers. Shortage claims measured at the vessel settle on evidence instead of estimates.
Banks & financiers. The financed tonnage exists because an independent hand measured it.
Lawyers & adjusters. A calculation shown line by line survives the scrutiny a summary never could.
Charterers & owners. The draft figure closes laytime, shortage, and bill-of-lading arguments before they grow teeth.
Named surveyor, scope in writing. Before anything starts you know who attends, when, and exactly what they will do, on paper.
The fee agreed first. The fee is put in writing before work begins, so the decision is made with the numbers in front of you.
One interest per matter. If we act for the other side in your dispute, we tell you and decline. Independence is the product.
Work starts on your go-ahead. Nothing begins until you confirm in writing, findings reach you first, and we answer 24/7.
Read properly at all marks with corrections from the vessel’s own tables, a draft survey determines bulk weight to the tolerance the trade settles on, and its strength is independence: the vessel’s displacement is the one scale no commercial party owns.
Each survey is an attendance of hours, fitted to the vessel’s operation: initial before cargo moves, final when it stops, certificate to follow with every line of the working shown.
Scope sets the fee: full initial-and-final, intermediates on split parcels, or a joint survey both sides sign. It comes back in writing before work begins, and a single recovered shortage pays for a season of surveys.
Yes, and lightering and barge operations between them, through our own local surveyors at the port, with every attendance confirmed in writing before work begins, with the attendance confirmed in writing before work begins.
Draft surveys at Libreville Port, Gabon are carried out by Observater Surveys and Services Group: independent, resident at the port, and answering around the clock. One email to the desk brings back the surveyor’s name and scope in writing, and attendance follows day or night.
It depends on the scope — the operation, the hours, and what must be attended. What never varies is the sequence: the fee is quoted in writing before attendance, agreed before boarding, and there are no additions invented afterwards. One email describing the vessel and the operation brings the figure back.
Before loading or discharge begins and again at completion: the figure is the difference between two readings, and both must be independent for the tonnage to stand.
Evidence is cheap while it exists, and priceless once it is gone
The receiver has paid before the loss appears. The shipper argues from documents after sailing. The owner and the charterer settle against each other’s numbers, the club pays what the evidence supports, and the bank lends against cargo it never sees. Whichever side of the file you are on, send the details, and the surveyor’s name, the attendance time, and the fee reach you in writing before anything begins. One interest per matter: your appointment is exclusive, and the findings come to you first.

From the Observater Desk
Every call at Libreville moves two commodities: the cargo on the quay and the fuel in the tanks. The bunker desk closes the second one with independent soundings, sealed samples, and a certified figure — on the same instruction line as the matter that brought you here.
