Marine Services
Marine Services by Global Surveys support shipowners, charterers, cargo owners, traders, insurers, terminals, logistics teams, and supply chain parties. The service scope includes draft survey, ullage survey, bunker survey, on/off hire survey, reefer PTI, sealing, unsealing, carrier cleanliness inspection, ultrasonic leakage detection, hose test, and clear marine reports.
As a TIC Council member and ISO/IEC 17020:2012 accredited inspection body for defined inspection activities, where applicable, Global Surveys helps clients protect cargo value, verify quantity, reduce disputes, and improve shipment control. In addition, our reports help document vessel or cargo condition before, during, and after marine operations.
Marine Services for Cargo, Vessel and Port Operations
Maritime trade depends on reliable quantity checks, cargo condition control, vessel readiness, secure transport, and clear documentation. Therefore, Global Surveys provides independent marine survey and supervision services for loading, discharge, bunkering, chartering, storage, transport, and shipment handover. Also, these services help clients act early when quantity, condition, cleanliness, leakage, or shipment integrity issues are observed.
Marine Quantity and Measurement Surveys
Quantity differences can create claims, delays, and commercial disputes. For that reason, marine quantity surveys help clients verify cargo, fuel, and liquid measurements using agreed methods and factual reporting. In practice, these checks support traders, owners, charterers, suppliers, terminals, and receivers when accurate quantity evidence is required.
Draft Survey
A draft survey helps estimate the quantity of cargo loaded on or discharged from a vessel by using vessel draft readings and related calculations. As a result, traders and cargo owners receive independent quantity support before and after loading or discharge.
- Initial and final draft readings
- Loading or discharge quantity support
- Vessel and cargo observations
- Draft survey report
Ullage Survey
An ullage survey supports liquid cargo quantity control by measuring the empty space between the liquid surface and the upper reference point of the tank. In addition, it helps parties review liquid cargo quantity before or after transfer.
- Tank measurement support
- Liquid cargo quantity checks
- Ullage and related observations
- Ullage survey report
Bunker Survey
A bunker survey helps measure the quantity of fuel delivered to or remaining on a vessel during bunkering or related operations. Therefore, shipowners, charterers, and suppliers can reduce quantity disputes and strengthen fuel delivery records.
- Pre-bunkering checks
- Post-bunkering measurements
- Bunker delivery support
- Bunker survey report
Vessel Condition, Charter and Hire Surveys
Vessel condition evidence is important when a vessel is placed on hire or returned from hire. Therefore, on/off hire survey support helps concerned parties document vessel condition, bunkers, holds, equipment, and visible findings. Also, the report can support charter discussions, liability review, and commercial settlement.
On/Off Hire Survey
On/off hire surveys help charterers, owners, and other parties record vessel condition at the start or end of a charter period. Also, they support liability control by documenting visible condition and work required under the agreed scope.
- Vessel condition observations
- Hire or off-hire documentation support
- Bunker and hold-related notes where applicable
- On/off hire survey report
Carrier Cleanliness Inspection
Carrier cleanliness inspection helps confirm whether vessel holds, containers, trucks, or other transport units are visibly clean and ready to receive the intended cargo. As a result, clients can reduce contamination, rejection, and loading delay risks.
- Hold or container cleanliness checks
- Visible residue and contamination notes
- Readiness observations
- Cleanliness inspection report
Reefer and Cargo Readiness Services
Temperature-sensitive cargo needs clean and reliable reefer equipment before loading. Therefore, reefer pre-trip inspection helps reduce the risk of cargo loss, poor temperature control, or loading delays. In addition, cargo readiness checks support safer handling and better acceptance decisions.
Reefer Pre-Trip Inspection
Reefer Pre-Trip Inspection helps confirm that a reefer unit is clean, operating properly, and ready to receive the intended shipment before loading. In addition, it supports safer movement of food, pharmaceuticals, and other temperature-sensitive goods where applicable.
- Reefer cleanliness checks
- Operational readiness review
- Temperature control observations
- PTI report support
Cargo Condition Checks
Cargo condition checks support loading and discharge decisions by recording visible condition, packing, markings, handling concerns, and signs of damage. Also, they help parties manage claims or acceptance decisions.
- Visible cargo condition notes
- Packing and marking review
- Damage or contamination observations
- Photo evidence where applicable
Loading and Discharge Support
Marine supervision can support loading or discharge operations by documenting cargo flow, handling, condition, delays, and visible findings. As a result, clients receive clearer evidence across key cargo movement stages.
- Loading observations
- Discharge observations
- Handling and delay notes
- Operation report support
Sealing, Unsealing and Shipment Integrity
Shipment integrity depends on secure seals, clear seal numbers, and proper seal condition checks. Therefore, sealing and unsealing services help clients reduce manipulation risk and improve traceability during cargo transport. Also, these records can support handover, discharge, and claim review.
Sealing Service
Sealing service helps secure loaded shipments in vessel holds, containers, trucks, or other transport units using numbered tamper-evident seals. In addition, seal records support traceability and shipment control.
- Tamper-evident seal application
- Seal number recording
- Loaded shipment protection
- Sealing report support
Unsealing Service
Unsealing service helps verify seal integrity before seals are broken at discharge or delivery. Therefore, clients can document whether the shipment appears to have remained secured during transport.
- Seal integrity checks
- Seal number verification
- Unsealing observations
- Unsealing report support
Leakage, Tightness and Weathertightness Services
Water ingress, leakage, and weak tightness can damage cargo and create disputes. For that reason, leakage and tightness checks help clients confirm whether selected areas are ready for loading or require further action. Moreover, early detection can reduce cargo loss, delay, and safety risk.
Ultrasonic Leakage Detection
Ultrasonic Leakage Detection helps identify leaks or defects in selected structures such as vessels, hatch covers, tanks, pipelines, and related equipment. As a result, clients can detect concerns early and reduce the risk of cargo damage, downtime, or safety issues.
- Ultrasonic leak detection support
- Hatch cover or structure checks where applicable
- Leakage finding notes
- ULD report support
Hose Test
Hose Test service helps check whether vessel holds or selected areas are weathertight and ready to receive cargo before loading. In addition, it supports cargo protection and loading readiness decisions.
- Weathertightness checks
- Hold readiness observations
- Leakage or water ingress notes
- Hose test report support
