Observater Surveys and Services Group · Warri Port · Delta State · Western Delta
Our cargo surveyors in Warri attend 24/7 across the general cargo and liquid trade of the western delta: tally and out-turn surveys, steel and breakbulk condition, liquid and petroleum inspections, bunker surveys, vessel condition attendance, cargo damage surveys, P&I cargo surveys, loss control, and cargo claims, with who attends, when, and on what basis confirmed in writing before work begins.
Importers, shippers, insurers, P&I clubs, charterers, shipping lines, banks, and forwarders all instruct the same surveyors, under one rule: one interest per matter. Appointed before the vessel berths is best; appointed after the problem shows, we build the file from what remains.
Get a Surveyor Moving Email the InstructionThe out-turn and the manifest disagree. General cargo lands short or damaged, and without an independent count the difference is decided by whoever kept the only tally.
The steel rejection has no chemistry. Rust on coils and plates is either atmospheric sweat or seawater wetting, and the answer decides who pays. Silver nitrate testing turns the rejection argument into a laboratory result.
The liquid figure changed between tanks. A petroleum transfer ends with the shore and the ship apart on paper. Ullage, temperature, and API/ASTM calculation, stated with the arithmetic attached, is the figure that survives.
The fuel was paid for unmeasured. A bunker delivery note is a claim, not a measurement. Measuring the vessel’s and the barge’s tanks before and after transfer is what makes it checkable.
Our highly trained cargo surveyors carry out all types of cargo surveys, cargo inspections, and cargo superintendence at Warri Port, Nigeria: general and breakbulk cargo, steel, liquid and petroleum, bunker, vessel condition, damage, and claims, at the same reporting standard the Lagos file carries. One instruction covers every survey type, findings reach the instructing party first, and the full Nigeria practice runs from our country desk: Marine and Cargo Surveys in Nigeria, with dedicated attendance at Lagos and every other major Nigerian port.
Whatever the cargo over Warri, the discipline is the same: condition and count recorded independently, and cargo damage surveys attending the same day when something goes wrong.
The agricultural trade through the Port of Warri and the western delta berths settles on moisture, count, and condition, and each commodity fails in its own way. Our surveyors work them commodity by commodity, with sampling to recognized standards and sealed splits retained for every dispute that follows.
Fertilizer is hygroscopic: it draws moisture from the air and cakes by the hour once wet. Our fertilizer cargo surveys watch moisture from hatch opening to the weighbridge, sample and seal splits at each stage, supervise protection between rains, and put the tonnage on an independent draft figure the invoice must answer to.
Wheat and bulk grain settle on the draft survey and fail on moisture, heat, and infestation. Our grain cargo surveys measure the vessel before and after discharge, sample for moisture and condition to recognized standards, supervise fumigation where ordered, and reconcile the out-turn so the mill, the trader, and the insurer read one figure.
Rice moves in bags and is lost bag by bag: torn at the sling, wetted in the stack, short at the warehouse door. Our rice cargo surveys count at the hatches and the doors, separate sound from damaged as cargo lands, and fix the out-turn in writing, so the shortage argument runs on a count instead of a guess.
Foodstuffs and general agricultural cargo over the Port of Warri get condition and count fixed as they land: tally at the hooks and the doors, damaged cargo segregated before it spreads, sampling with sealed splits retained, and an out-turn report every interest can read.
Our tally clerks and cargo superintendents work Warri’s berths around the clock: each piece and unit counted as it lands, sound separated from damaged before stacking makes the two impossible to tell apart, and an out-turn survey reconciling the manifested quantity against what actually arrived. Steel gets piece-by-piece condition surveys with silver nitrate testing, so coils, plates, and pipes carry a chemistry-backed condition record instead of an opinion.
The western delta moves liquid cargo daily, and our inspectors run the full discipline: tank cleanliness, first foot and pre-load samples, ullage and temperature measurement, shore tank gauging, and API/ASTM calculation with samples sealed at the manifold. Our bunker surveyors attend on/off hire and quantity surveys at delivery and redelivery, the two points where fuel is paid for, with soundings on our own instruments and the delivery note verified against what was measured.
Vessel condition and on/off hire surveys run at the same call, holds and hatch covers inspected before loading commences, with the full vessel-side practice with our marine surveyors in Warri. Our cargo damage surveys in Warri move the same day cargo arrives wet, rusted, contaminated, or short: cause, nature, and extent investigated while the evidence exists, segregation stopping further loss, and the claim file built to the standard adjusters accept, with findings reaching the instructing party first and in confidence.
Most cold chain instructions in Nigeria begin after the damage: a reefer container opened to spoiled fish, thawed meat, or fruit past saving, and every party holding a different theory of when the cold was lost. The survey establishes what actually happened instead of what each party assumes: the data logger read in full rather than its summary, set points compared against delivered temperatures, pulp temperatures taken across the stow, pre-cooling and stuffing practice examined, and power and plug records reviewed, so responsibility follows the evidence to the leg where the loss occurred.
Salvageable cargo is segregated at the same attendance, quantum measured rather than estimated, and the file built for the importer, the insurer, or the shipping line, whichever interest instructs first, one appointment per matter.
Warri loads as well as it lands: petroleum products, general cargo, and agricultural exports leave through the western delta, and the loading figures decide every invoice that follows. Our loading surveyors inspect holds and tanks before loading commences, fix the loaded quantity by draft survey and tally, supervise stowage and securing, and issue certificates to the contract’s wording, with sampling and sealed splits retained for the dispute that never gets to start.
For petroleum product loadings, our liquid cargo superintendence reconciles shore tank and ship figures with ullage, temperature, and density applied, samples sealed at the manifold, and letters of protest issued while they matter, for shippers, traders, and the banks behind the parcel.
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.
Steel and general cargo lose value by the day when nobody controls the loss: rust spreads from the wet coils to the dry ones stacked against them, handling damage multiplies at every move, and by the time the receiver complains, the damage can no longer be dated. Our loss control surveyors stop the clock: damaged pieces segregated as they land, protection arranged before the next rain, stevedore damage recorded and protested the same shift, and the condition of what remains fixed in writing while it is still provable.
For P&I clubs, correspondents, and carriers facing cargo claims in Warri, our P&I cargo surveys measure the claim before it is paid: quantum counted rather than accepted, pre-shipment rust separated from voyage wetting by silver nitrate testing, and the file assembled so the claim settles on chemistry and counts, one interest per matter.
One team, one fight
Warri’s cargo feeds the western delta and the interior, and most surveying arrangements end at the port gate, with everything after it unrecorded; ours continues. The record that starts at the ship’s rail follows the cargo through the group’s active operations across West Africa, so a discrepancy found inland reads back to the leg that caused it.

We answer 24/7, and a surveyor can be moving to any Warri berth at short notice, with attendance confirmed in writing before work begins.
Yes: tank cleanliness, first foot samples, ullage and temperature, shore tank gauging, API/ASTM calculation, and contamination investigation, with samples drawn and sealed at the manifold.
Yes, piece by piece, with silver nitrate testing that separates atmospheric sweat from seawater wetting, so a rust rejection runs on chemistry rather than opinion.
Yes: Lagos, Port Harcourt, Onne, and Calabar, with the same discipline at each, with our marine and cargo surveys in Nigeria.
Yes. Our loading surveys in Warri cover pre-loading holds inspections, draft surveys and tally at loading, stowage and securing checks, and certificates written to the contract and letter of credit. Petroleum product loadings get liquid cargo superintendence with shore tank and ship figures reconciled and samples sealed at the manifold.
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, and the findings reach you first, in confidence. We answer 24/7.
The fee depends on the scope: the cargo, the number of attendances, and what must be measured or sampled. Tell us the vessel or the consignment and we reply with the scope and the fee in writing before work begins, so the decision is made with the numbers in front of you.
Cargo surveys at Warri Port, Nigeria 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 the hatches open, ideally — the record is strongest when independent eyes see the first sling. Where damage is already on the quay, the answer is simply as soon as possible: evidence fades with every re-handling.
The figure taken today settles the argument that comes later
Tell us the vessel, the container numbers, or the problem, and our surveyors confirm who attends, when, and on what basis, in writing, before anything starts.

From the Observater Desk
Every call at Warri 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.
