Observater Surveys and Services Group · Onne Port · Oil & Gas Free Zone · Rivers State
Our cargo surveyors in Onne attend 24/7 at the heart of Nigeria’s oil and gas logistics: project cargo and heavy lift supervision, marine warranty surveys, out-of-gauge units, equipment and vessel suitability, lashing and sea-fastening verification, container and general cargo surveys, cargo damage surveys, P&I cargo surveys, loss control, and cargo claims, with scope 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.

The warranty clause has conditions. High-value marine operations are insured on warranties, and cover can be disputed if the warranty surveyor’s conditions were not met. MWS sign-off before the operation is what keeps the policy behind the lift.
The lifting gear is assumed, not checked. Certificates say what the crane could do at its last test, not whether this rigging suits this unit today. Equipment suitability is verified against the load, or it is guesswork.
The road commits before anyone looks. An abnormal load on an unaudited route meets its weak bridge or tight turn at the worst possible time. Route surveys and transport audits happen before the convoy moves, or the schedule pays.
Our highly trained cargo surveyors and project surveyors carry out all types of cargo surveys, cargo inspections, and cargo superintendence at Onne Port, Nigeria: heavy lift and out-of-gauge supervision, marine warranty survey interfaces, lashing and securing, container and general cargo, vessel suitability, damage, and claims, to the standard underwriters and the energy sector work from. 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 lands at Onne, from a process module to a container of spares, the discipline is the same: condition recorded at every handover, and cargo damage surveys attending the same day when something goes wrong.
The equipment building Nigeria’s energy projects lands at Onne, and it is expensive to buy and worse to replace. Our project cargo surveyors supervise discharge and loading lifts, review lift plans and method statements, verify lifting gear and equipment suitability against the unit, check lashing and sea-fastening before each leg, and provide marine warranty survey interfaces that satisfy the insurance policy’s warranty clause, with sign-off documentation underwriters and project owners read from the same page.
The risk does not end at the quay. Our surveyors inspect storage yards while units wait, audit trucks, transporters, and routes before the road commits, and record condition at every handover, so an out-of-gauge unit that arrives at the project site damaged carries the leg it happened on instead of arriving as an argument. Machinery on wheels and project rolling stock get the same discipline.
Alongside the project trade, our surveyors attend containers and general cargo at Onne: condition and seal surveys, devanning attendance, and tally. Vessel condition, on/off hire, and bunker surveys run at the same call, with the full vessel-side practice on our page for marine surveyors in Onne, and when something goes wrong, our cargo damage surveys at Onne move the same day, with cause, custody, and quantum documented and the claim file built to the standard adjusters accept, findings reaching the instructing party first.
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.
Onne loads Nigeria’s fertilizer exports: urea leaves through the port in shiploads, and every cargo is priced on the tonnage and condition fixed at loading. Our loading surveyors inspect holds before loading commences, watch moisture from the warehouse to the hatch, fix the loaded quantity by draft survey, supervise trimming and hatch closing against the weather, and issue certificates written to the contract and the letter of credit, so the parcel arrives at the buyer’s port already carrying its proof.
The oil and gas trade loads here too: project backloads, equipment returning from the field, and petroleum products, with condition recorded before the sea leg, securing verified, and liquid loadings attended with independent figures, samples sealed, and protests issued at the time.
A project unit does not need to be dropped to be lost: it can rust in an open yard, take handling damage at every move, and arrive at the site with its warranty position argued away because nobody recorded when the damage happened. Our loss control surveyors keep the exposure small: storage conditions checked while the unit waits, protection arranged before the weather turns, every lift and move attended, and condition recorded at each handover, so the unit’s file always says where it stood and when.
For P&I clubs, carriers, and their correspondents facing claims over project and containerized cargo at Onne, our P&I cargo surveys measure the claim before it is paid: damage dated against the custody chain, quantum measured rather than accepted, and the file assembled so the claim settles on evidence, one interest per matter.
One team, one fight
A unit over Onne is bound for a project site, and the file that protects it must travel the whole way: the lift record at the quay, the condition record at each handover, and the route audit before the road. Most arrangements end at the port gate, with everything after it unrecorded; ours continues to the site, through the group’s active operations across West Africa.
