The HERMetic DIP Type 2 GT is a specialized tool for ensuring that the bottom of closed and inerted tanks is dry and free of deposits after crude oil washing. It features a graduated brass/stainless steel weight and a graduated stainless steel tape wound on a reel, with an adapter for connecting to a HERMetic valve. This device operates under closed conditions, preventing vapor escape into the atmosphere. Additionally, it can estimate the distance between the tank bottom and the zero reference level. The tape features both metric and inch scales and is classified as class II accuracy.
Maintaining cargo tank integrity is essential for safe tanker operations. Reliable tank bottom verification helps prevent contamination, improve efficiency, and support marine safety compliance.It also enables operators to detect water, sludge, and sediment buildup before these conditions affect cargo quality or vessel performance. By carrying out accurate inspections within a controlled and closed environment, marine operators can reduce operational risks, protect personnel, and maintain higher standards of safety and environmental responsibility.
The HERMetic DIP Type 2 GT is a gas-tight dipping device for closed tank bottom inspection, sludge detection, water interface measurement, and dryness checks without opening the tank atmosphere.

- Connection: Comes with an adapter for connecting to a HERMetic valve.
- Operation: Functions under closed conditions, preventing vapor escape.
- Dual Scales: Tape shows both metric and inch scales.
- Accuracy: Class II accuracy (+/- 6 mm over 30 meters or +/- 1/4″ over 100 ft).
- Measurement: Can estimate the distance between the tank bottom and the zero reference level.
Key Benefits: -
- Dryness and Cleanliness Check: Ensures the bottom of closed, inerted tanks is dry and free of deposits after crude oil washing.
- Precise Measurement: Features a graduated brass/stainless steel weight and tape for accurate readings.
- Closed Operation: Operates under closed conditions to prevent vapor escape into the atmosphere.
- Dual Scale Tape: Offers both metric and inch scales on the same side of the tape for versatile measurement.
- Class II Accuracy: Provides high precision with +/- 6 mm accuracy over 30 meters (approximately +/- 1/4″ over 100 ft).
- Distance Estimation: Can estimate the distance between the tank bottom and the zero reference level for accurate assessment.
- Zero Reference: The tip end of the dipping rod is aligned with the zero of the tape for precise measurements.
Reduced Vapour Release During Closed Tank Inspection
The HERMetic DIP 2 GT is designed for gas-tight closed tank inspection, helping minimise the release of hazardous cargo vapours during tank bottom checking. Its sealed operating mechanism allows measurements to be performed through the compatible HERMetic quick-connect and vapour control system without unnecessarily opening the cargo tank. This supports safer onboard operations, reduces potential personnel exposure to cargo vapours, and helps maintain controlled conditions within inerted and closed cargo tanks.
Tank Cleaning & Crude Oil Washing Verification
The HERMetic DIP 2 GT provides a practical solution for verifying cargo tank bottom conditions after tank cleaning and crude oil washing (COW) operations. By allowing operators to check the tank bottom through a closed, gas-tight connection, the device helps identify the presence of remaining liquid, water, sludge, sediment, or other residues that may remain after cleaning.
This tank bottom verification capability supports tanker operators, ship crews, surveyors, and inspection personnel in assessing whether the cargo tank has been adequately cleaned and is ready for subsequent cargo operations. Its manual graduated measuring system provides a straightforward and reliable method for closed tank inspection and cleaning verification while helping maintain safer operating conditions.
Design and Construction
The system incorporates a gas-tight connection mechanism that interfaces with compatible HERMetic vapor control valves, allowing operators to complete inspections without opening the cargo tank.
