Obtaining representative cargo samples is an important part of petroleum and marine cargo operations. However, sampling hazardous liquids from cargo tanks can expose personnel to potentially harmful vapors and may result in unnecessary emissions when conventional open sampling methods are used.
The HERMetic Sampler GT is a closed gas-tight liquid sampling system designed to collect representative samples from cargo and storage tanks while maintaining controlled tank conditions.
The system is suitable for hydrocarbon products, hazardous liquid cargoes, marine tankers, petroleum terminals, refineries, and offshore installations where safe and controlled sampling is required.
SMTS Marine Solutions LLC supplies HERMetic sampling equipment, accessories, spare parts, and technical support for marine and petroleum applications.
Reliable Closed Sampling Solution for Tankers, Terminals and Offshore Facilities
What Is the HERMetic Sampler GT?
The HERMetic Sampler GT is a portable liquid sampling device designed for obtaining samples from cargo tanks through a compatible HERMetic deck valve.
The system can accommodate a sample volume of up to 0.47 litres, depending on the sampling configuration.
A graduated tape is used to position the sampling bottle at the required tank level. After collection, the liquid can be transferred into a laboratory container through the integrated distribution arrangement.
Main Sampling Capabilities
The HERMetic Sampler GT can support:
- Zone sampling
- Spot sampling
- Bottom sampling
- Running sampling
- Cargo quality verification
- Laboratory analysis
- Water and sediment checks
- Cargo condition assessment
How the HERMetic Sampler GT Performs Tank Sampling
The system is installed onto a compatible HERMetic deck valve using the appropriate adaptor.
Once connected, the sampling bottle can be lowered into the tank using the graduated tape.
Typical Sampling Procedure
- Connect the sampler to the compatible HERMetic deck valve.
- Confirm that the equipment and connection are correctly secured.
- Lower the sampling bottle to the required tank depth.
- Use the graduated tape to determine the sampling position.
- Collect the liquid sample under closed conditions.
- Transfer the collected sample through the distribution block.
- Remove the sampling bottle after completing the operation.
- Secure the equipment following the applicable operating procedure.
The exact procedure may vary according to the sampling method, cargo, vessel arrangement, and applicable safety requirements.
Sampling Methods Supported by HERMetic Sampler GT
Zone Sampling
Zone sampling collects liquid from a defined section of the tank. This can be useful for assessing product consistency at a particular tank level.
Spot Sampling
Spot sampling involves collecting a sample at a predetermined depth.
It is useful when a specific tank location needs to be analyzed separately.
Bottom Sampling
Bottom sampling allows operators to obtain material from the lower section of the tank.
This can assist in identifying:
- Free water
- Sediment
- Sludge
- Contamination
- Other tank-bottom residues
Running Sampling
Running sampling collects liquid while the sampling bottle passes through different levels of the tank.
This can provide a more representative sample of the product throughout the sampled tank section.
Key Features of HERMetic Sampler GT
Gas-Tight Sampling
The closed sampling arrangement is designed to minimize vapor release during liquid sample collection.
Graduated Sampling Tape
The graduated tape enables the operator to position the sampling bottle at the required depth.
30 Metre Measuring Tape
The standard specification includes a 30 m / 100 ft graduated tape, providing sufficient reach for many cargo tank sampling applications.
0.47 Litre Sampling Capacity
The system is designed for liquid sample collection of up to approximately 0.47 litres.
HERMetic Deck Valve Compatibility
The sampler is designed for connection to compatible HERMetic 2-inch deck valves using suitable adaptors.
Gravity-Based Sample Transfer
The collected liquid can be transferred into a laboratory bottle through the dedicated distribution arrangement.
Multiple Sampling Configurations
Different sampling bottle configurations can be used for zone, spot, bottom, and running sampling requirements.
