Our cargo surveyors in Port Harcourt attend 24/7 across the bulk, liquid, and energy trade of the eastern gateway: draft surveys, tally and out-turn, bunker surveys, liquid and petroleum inspections, hull and machinery surveys, casualty investigation, P&I 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 shore tank and the ship disagree. A liquid transfer ends with two different quantities on paper, and the difference is real money. Independent ullage, temperature, and API/ASTM calculation state one figure with the arithmetic attached.
The bunker delivery note is not the measurement. What the note says came aboard and what actually came aboard are two different questions. Only measuring the vessel’s and the barge’s tanks before and after transfer answers the second one.
The casualty evidence sails away. After a grounding, a collision, or machinery damage, the vessel leaves and the evidence leaves with it. A casualty investigator on board in the first hours is the difference between a reconstructed sequence of events and a guess.
The bulk shortage lands on somebody. A wheat or fertilizer discharge hundreds of tonnes apart on paper becomes a claim against whoever cannot produce an independent figure.
Our highly trained cargo surveyors carry out all types of cargo surveys, cargo inspections, and cargo superintendence at Port Harcourt, Nigeria: bulk and bagged cargo, liquid and petroleum, containers, and every trade of the eastern rivers, with the vessel side, hull and machinery, casualty, and claims attended by the same marine team at the river berths and the terminals alike. One instruction covers every survey type, findings reach the instructing party first, and the full Nigeria practice runs from our country page: Marine and Cargo Surveys in Nigeria, with dedicated attendance at Lagos and every other major Nigerian port.
Whatever the cargo over Port Harcourt, 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 Port Harcourt and the eastern river 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.
Sugar and bulk foodstuffs over Port Harcourt settle on the draft and survive on condition: our surveyors fix the tonnage before and after discharge, watch the weather and the hatches, segregate wet cargo the shift it appears, and write the out-turn all interests can settle on.
For bulk parcels over Port Harcourt, our draft surveyors measure the vessel before the operation begins and again when it ends; the difference between the two results is the cargo weight, with readings at six points, density sampled at the time of reading, and the full calculation attached. Tally clerks count at the hatches and gates around the clock, and an out-turn survey reconciles the manifested quantity against what actually landed, so the receiver, the carrier, and the insurer read one result instead of three.
Port Harcourt’s biggest cargo moves in liquid form, and every transfer point is a place where quantity can change on paper. Our inspectors run tank cleanliness checks, first foot and pre-load samples, ullage and temperature measurement, shore tank gauging, and API/ASTM calculation, with samples drawn and sealed at the manifold.
Our bunker surveyors in Port Harcourt attend on/off hire bunker surveys and bunker quantity surveys at delivery and redelivery, the two points where fuel is paid for: soundings on our own instruments, the bunker delivery note verified against what was actually measured, and shortage investigations pursued to their source.
Our cargo damage surveys in Port Harcourt move the same day cargo arrives wet, torn, contaminated, or short: cause, nature, and extent investigated while the evidence exists, further loss stopped by segregation, and the claim file built to the standard adjusters accept. When a vessel suffers damage in the eastern waters, our hull and machinery surveyors investigate the cause, nature, and extent for underwriters and shipowners, stated in the form adjusters and average agreements use, and marine casualty investigators attend while the evidence is still on board. For P&I clubs and marine insurers, attendance is impartial, one interest per matter, with flash findings inside a day. The full vessel-side practice runs from our page for marine surveyors in Port Harcourt. Cargo damage surveys move the same day, and our claims handlers build the file to the standard adjusters accept and pursue it to recovery.
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.
The eastern rivers load as well as they discharge: urea and fertilizer exports, petroleum products, and general cargo all leave through Port Harcourt, and every parcel is priced on the figures fixed at loading. Our loading surveyors inspect holds before loading commences, fix the loaded quantity by draft survey and tally, supervise stowage and weather protection, sample and seal splits for quality, and issue certificates to the contract’s wording, so the exporter’s file reaches the buyer before the argument can.
For crude oil and petroleum product loadings at the terminals of the eastern delta, our liquid cargo superintendence attends on instruction, through the group and its vetted network: independent ullage and shore tank figures, temperature and density applied, samples sealed at the manifold, OBQ and ROB established, and every discrepancy protested in writing at the time, not remembered afterward.
A bulk discharge without loss control pays twice: once for the cargo lost to spillage, grab damage, and rain squalls, and again for the argument about whose fault it was. Our loss control surveyors supervise the discharge as it runs: hatches watched against the weather, spillage swept and recovered under supervision, wet or contaminated cargo segregated the moment it appears, and every stevedore incident recorded and protested the same shift, so the loss stops growing while it is still small.
For P&I clubs, correspondents, and carriers facing cargo claims in Port Harcourt, our P&I cargo surveys measure the claim before it is paid: quantum counted rather than accepted, pre-existing condition separated from voyage damage, and the file assembled so an inflated claim shrinks to what the evidence supports, one interest per matter.
One team, one fight
Cargo over Port Harcourt feeds the industrial belt through Enugu toward Abuja, 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 shortage or damage discovered inland reads back to the leg that caused it.

“The bunker delivery note said one figure, their soundings said another. The difference paid for the survey many times over.”
Ship operator, Port Harcourt
“Shore tank and ship figures reconciled, with the arithmetic attached. One number left the terminal.”
