Observater Surveys and Services Group · Port Harcourt · Bonny River · Eastern Nigeria
Our marine surveyors in Port Harcourt attend vessels at the river berths, the terminals, and the anchorage 24/7: vessel condition surveys, on-hire and off-hire surveys, hull and machinery damage surveys, marine casualty investigation, P&I attendance, holds and hatch cover inspections, and bunker surveys, with scope confirmed in writing before work begins.
The vessel is the most expensive thing in every maritime dispute, and the party without an independent marine surveyor argues about it from the other side’s report. Shipowners, managers, charterers, H&M underwriters, and P&I clubs all instruct the same surveyors, under one rule: one interest per matter.

The casualty evidence sails away. After a grounding, a collision, or machinery failure in the eastern waters, the vessel leaves and the evidence leaves with it. The first hours on board decide what the file will ever contain.
The off-hire condition is a memory. A vessel redelivers and the damage argument starts. Without an on-hire survey to compare against, the answer is whoever shouts longest.
The repair bill arrives without a referee. After machinery damage, the yard’s scope and the owner’s scope rarely match. An independent survey of cause and extent is the figure all sides can argue from.
Our highly trained marine surveyors carry out all types of marine surveys, ship surveys, and vessel inspections at Port Harcourt, Nigeria: vessel condition, on/off hire, hull and machinery, casualty, P&I, holds and hatch covers, and bunker surveys, at the berth and at anchorage. Cargo, tally, draft, and claims run from our page for cargo and marine surveyors in Port Harcourt, and the full country practice from Marine and Cargo Surveys in Nigeria.
Every charter starts and ends with a condition question, and on the river trade the question has teeth. Our surveyors attend on-hire and off-hire surveys at Port Harcourt: hull, decks, holds, hatch covers, and equipment recorded compartment by compartment, existing damage photographed and listed, and bunkers established at the same attendance. Holds and hatch cover inspections before loading confirm the spaces are clean, dry, and fit to receive the booked cargo, while there is still time to correct what is not.
When a vessel suffers damage on the Bonny River or in the eastern approaches, our hull and machinery surveyors investigate the cause, nature, and extent for underwriters and shipowners, stated in the form adjusters and average agreements use, with repair scopes reviewed and costs followed to completion. Marine casualty investigators attend while the evidence is still on board: statements taken, records secured, and the sequence of events reconstructed in a report written to be used in a negotiation, an adjustment, or a courtroom.
For P&I clubs, members, and marine insurers, our surveyors provide impartial attendance in Port Harcourt, one interest per matter, with flash findings inside a day and reports to the standard the club applies. Bunker surveyors attend at delivery and redelivery, the two points where fuel is paid for, with soundings on our own instruments and the bunker delivery note verified against what was actually measured.
One team, one fight
The same marine surveying discipline runs at Lagos, Port Harcourt, Onne, Warri, and Calabar, so a vessel calling more than one Nigerian port keeps one file, one standard, and one point of contact for the whole rotation. Findings reach the instructing party first, and the report reads the same wherever it was written.
