HERMetic Sampler A-2
Accurate cargo sampling is a critical requirement in marine transportation, offshore production, and petroleum storage operations. Sampling integrity directly impacts custody transfer accuracy, product valuation, regulatory compliance, and laboratory analysis outcomes.
The HERMetic Sampler A-2 is a precision-engineered restricted cargo sampling system designed for controlled extraction of liquid samples from cargo tanks, storage tanks, offshore units, and terminal facilities. The system is developed for use in hazardous environments where safe sampling.
SWIFT MARINE TECH SERVICES PTE LTD supplies certified HERMetic sampling systems and marine cargo control instrumentation to operators across Singapore, the Asia-Pacific region, and global maritime markets, supporting tanker fleets, offshore installations, refineries, and terminal operators with OEM-grade technical solutions.
HERMetic Sampler A-2 Closed Cargo Sampling System for Marine, Offshore and Petroleum Applications | SWIFT MARINE TECH SERVICES PTE LTD
The HERMetic Sampler A-2 is a portable cargo sampling instrument developed for restricted and open sampling applications where representative liquid samples are required for inspection, laboratory analysis, and cargo quality verification.
Its rugged marine-grade construction, precision sampling mechanism, and user-friendly operation make it suitable for routine onboard inspections as well as critical commercial and regulatory sampling activities.
The system supports accurate sampling of:
- Crude oil
- Refined petroleum products
- Hydrocarbons
- Chemical cargoes
- Liquid bulk products
- Storage tank contents
Designed for demanding marine environments, the HERMetic Sampler A-2 delivers reliable performance while minimizing operational complexity.
Technical Performance Characteristics
Sampling Accuracy and Representativeness
The system is designed to extract cargo samples from defined vertical tank profiles, ensuring representative composition across stratified cargo layers.
Controlled Vapor Exposure Interface
The HERMetic coupling interface enables sampling without direct tank opening, reducing vapor release and improving operational safety compliance.
Mechanical Reliability Under Marine Conditions
The system is engineered for repeated mechanical cycles under high humidity, salt exposure, vibration, and offshore motion conditions.
Depth-Controlled Sampling Precision
Graduated tape measurement ensures accurate positioning of sampling intervals within the cargo tank volume.
Compatibility with Standard Vapor Control Systems
Fully compatible with 2-inch HERMetic compact vapor control valves used across tanker fleets and terminal installations.
Operational Methodology
The HERMetic Sampler A-2 operates on a controlled descent and retrieval sampling principle. The device is lowered into the cargo tank through a compatible vapor control valve, allowing sampling at predetermined tank depths.
Sampling modes include:
- Spot Sampling (single-point extraction)
- Zone Sampling (stratified level sampling)
- Running Sampling (continuous depth traverse sampling)
- Bottom Sampling (sediment and interface sampling)
Each sampling method is executed under controlled conditions to ensure repeatability and representativeness of collected cargo specimens.
The system is suitable for both routine operational sampling and custody transfer verification procedures.
Engineering Construction and Mechanical Design
The HERMetic Sampler A-2 is constructed using marine-grade corrosion-resistant materials selected for long-term durability in offshore, tanker, and terminal environments. The system design is based on mechanical sampling actuation through a calibrated depth-controlled lowering mechanism.
The assembly integrates a precision sampling bottle system, controlled descent mechanism, and vapor-tight interface coupling to ensure operational stability during sampling cycles.
Principal Engineering Elements
- High-strength graduated measuring tape system (30 m standard configuration)
- Optional extended configuration (40 m)
- Precision sampling bottle assembly (~0.5 L capacity)
- Stainless steel structural components for corrosion resistance
- Brass and engineered alloy coupling interfaces
- Mechanical depth indication system with calibrated graduations
- Vapor-controlled connection interface for HERMetic 2-inch valves
The design ensures mechanical reliability under dynamic vessel motion, offshore environmental conditions, and terminal operational constraints.
System Definition and Functional Purpose
The HERMetic Sampler A-2 is a mechanically operated, portable cargo sampling device designed for use in restricted and controlled sampling environments. The system enables the extraction of representative liquid samples from defined tank levels while maintaining compatibility with vapor control interfaces.
- Representative sampling from defined tank strata
- Controlled exposure to hydrocarbon vapors
- Repeatable sampling accuracy across operational cycles
- Compatibility with standardized 2-inch HERMetic vapor control valves
- Safe operation in hazardous classified zones
The system is applicable to crude oil, petroleum products, refined fuels, and selected chemical cargoes where sampling integrity is required for commercial, operational, and regulatory purposes.
