Engineered to handle high-pressure chemical fluid control and corrosion-heavy operations in river and deepwater maritime zones.
The Democratic Republic of the Congo (DR Congo) represents one of the most critical resource hubs in the sub-Saharan region, demanding specialized port infrastructure. With key maritime corridors located in the Bas-Congo region—anchored by the historical river ports of Matadi and Boma, alongside the groundbreaking development of the deepwater port of Banana—the import and export of chemicals and hydrocarbon fluid components require maximum mechanical safety.
A significant driver of this demand is the copper and cobalt mining belt in the southeastern region. Refining these minerals requires massive amounts of reagent chemicals, particularly sulfuric acid, liquid sulfur, and extraction solvents. Because much of this raw chemical flow is imported by sea and transported inland via rail and road corridors, the transfer points at the maritime terminals are highly critical. Ensuring zero-emission, zero-spill operation is both an environmental necessity and an operational safety requirement.
Due to the unique challenges of the Congo River current and draft variations, terminal operators require Marine Chemical Loading Arms equipped with highly responsive swivel joint technologies and double counterweight systems to compensate for constant vessel movement.
Addressing environmental regulations, high safety protocols, and mechanical precision for volatile compound shipping.
Modern terminals mandate closed-loop fluid systems. Liquid chemical loading arms are now co-engineered with auxiliary gas recovery lines to capture vapor compounds, avoiding release into the port atmosphere.
To avoid disaster in case of sudden vessel drift, automated Emergency Release Couplers (ERC) instantaneously disconnect the arm, sealing the pipeline on both sides to prevent chemical spills.
Instead of manual operation, remote PLC-controlled electro-hydraulic systems guide loading arm alignments precisely, minimizing the risk of seal damage caused by incorrect docking.

The primary pivot point of any Marine Chemical Loading Arm lies within its swivel joint arrangement. Liftora designs features a split-path double track configuration utilizing hardened ball bearings. For acidic transfer situations, standard alloys fail rapidly. We implement a corrosion-resistant barrier using high-density PTFE and compound fluoroplastic seals, designed to isolate the metallic structure from reactive chemical media.
Dynamic seal systems operate under spring-energized mechanisms that ensure constant compression, accommodating thermal expansions when switching between high-pressure transfer cycles and purge procedures. The mechanical load is evenly distributed to prevent structural stress points that induce micro-cracks over extended fatigue cycles.
The Emergency Release System (ERS) is integrated within the lower arm assembly. Consisting of a dual-valve assembly with an interspaced coupling mechanism, it activates automatically through hydraulic signal lines upon detecting drift values exceeding preset limit zones. The internal logic isolates the transfer pipeline prior to physical breakaway, containing residual chemical volumes within the arm and vessel manifolds. This technology is vital for the DR Congo river environments, where unpredictable currents can push docked vessels beyond normal operational limits.
