Tank Gauging
Equipment
UTI Solutions
Al Safwan Marine supplies MMC UTI tank gauging equipment, cargo samplers, spares and retrofit solutions supporting accurate measurement and safe cargo handling across oil tankers, chemical tankers, product tankers, barges and FSOs.
Full range
UTI, samplers, valves, spares and retrofit kits
Up to 50 m
Petroleum & chemical gauging lengths
Ullage, temperature & interface measurement in one unit
MMC UTI tank gauging equipment combines three critical cargo measurements in a single portable unit, used aboard oil and chemical tankers, barges and FSOs during loading, unloading and cargo survey operations.
-
Ullage
Precise liquid level measurement from tank top to product surface.
-
Temperature
Accurate cargo temperature readings at any desired depth.
-
Interface
Clear detection of the oil / water interface for accurate custody transfer.
Restricted & Gas-Tight MMC UTI solutions
Selection depends on cargo type, vessel configuration, tank arrangement and operational requirements — with dedicated ranges for petroleum and IMO II & III chemical gauging.
Restricted UTI
Portable tank gauging for applicable restricted operations, reliably measuring ullage, temperature and interface.
15–50 mMMC Asia / UKGas-Tight UTI
Closed / gas-tight gauging arrangements for petroleum and chemical cargo operations, including IMO II & III service.
15–40 mPetroleum & ChemicalUTI spares & accessories
Sensor heads, gauging tapes, storage tubes, connector hubs and O-rings identified by exact part number.
Part-number matchedMatching the UTI to vessel and cargo type
Understanding IMO ship-type distinctions helps prevent incidents arising from proposing the wrong UTI for the cargo carried. See the IMO chemical tanker classification reference for further detail.
| Ship type | Hazard profile | Typical cargoes | Housing colour |
|---|---|---|---|
| Type 1 (ST1) | Very severe environmental / safety hazard, max. 1,250 m³ per tank | Acrylonitrile, benzene, chlorosulfonic acid | Red housing (high-hazard) |
| Type 2 (ST2) | Significant hazard, max. 3,000 m³ per tank | Ethylene dichloride, methyl methacrylate, phenol | Green housing (chemical) |
| Type 3 (ST3) | Moderate containment, no specific volume limit | Ethanol, propylene glycol, vegetable oils, petroleum | Black housing (petroleum) |
Restricted & Gas-Tight cargo samplers
Supporting controlled sampling requirements for petroleum and chemical cargoes, available in 20 m, 30 m and 40 m lengths.
Restricted samplers
SD-2/W, GTR/W, 51S600 configurations for controlled restricted sampling operations.
Gas-Tight samplers
CSTF-F/B, CSTF-F/R and chemical-service models including B2562-406-CHEM-40M.
Bottle holders & barrels
Sampling barrels, bottle holders and adaptors — certain configurations double as bottom-dryness checkers with an added DIP scale.
UTI replacement without re-engineering the vessel
MMC UTI equipment supports replacement of existing Tanksystem and TankTech installations, depending on compatibility and vessel configuration.
Existing valve
C2-SS (Tanksystem) or TVC-02 (TankTech) vapour control valve retained
Storage tube
TS-C2 / TVC-02 storage tube bridges the existing valve
B-type adaptor
MMC B-type storage tube connects the new UTI
MMC UTI installed
Same ullage read-out point maintained for continuity
Vapour control valve compatibility
Correct valve and adaptor compatibility is essential for reliable gauging and sampling. Adaptor solutions are available for the following arrangements:
