LNG Loading Arms in Action | Installation & Commissioning in the Caribbean

Carbis Loadtec recently supported the installation, commissioning and immediate operation of four LNG tanker loading stations in the Caribbean – a project that highlights how modern LNG loading arms can transform both safety and efficiency in cryogenic transfer operations.

Fast, Efficient Installation with Minimal Disruption

Each station, equipped with the CLGLA713 LNG Bottom Loading Arm, was installed with impressive efficiency. From unpacking to positioning, setting down and levelling, each unit was completed in approximately 15 minutes.

This level of speed is entirely achievable when:

Experienced installation teams are in place
Site access is well prepared
Work areas are free from interruption

Following installation, pipework connections were fabricated and completed within approximately one hour, allowing the system to move quickly into commissioning.

Commissioning in Cryogenic Conditions

Commissioning focused on ensuring precision, safety and operational readiness in a demanding LNG environment.

Key steps included:

Dimensional and alignment checks
Verticality verification
Pressure testing
Full system operation under live conditions

Aside from challenging weather conditions, the process was smooth – a reflection of both system design and site readiness.

Engineered for LNG Loading Arms: Materials and Configuration

The system was configured for LNG bottom loading with boil-off gas (BOG) return, ensuring safe handling of cryogenic fluids while effectively managing vapour.

Key technical features included:

316L stainless steel construction for durability and corrosion resistance
K-Flex insulation with stainless steel cladding to maintain cryogenic integrity
Insulated handles for safe, controlled and ergonomic operation

This combination ensures long-term reliability in extreme low-temperature environments, where both material performance and thermal management are critical.

Moving Beyond Hoses: A Step Change in Safety and Control

Prior to installation, the site relied on heavy hoses supported on davits, which introduced several operational challenges:

Manual handling strain
Risk of hoses being dropped or damaged
Liquid traps and surface icing
Reduced control during connection and disconnection

The transition to loading arms immediately eliminated these issues.

Unlike hoses, a correctly balanced loading arm:

Cannot be dropped or driven over
Maintains full control throughout operation
Removes physical strain from operators
Enables faster, more consistent connections

Operator Training and Immediate Impact

Operator training was a standout part of the project.
Teams were quick to engage with the system, with operators actively taking turns to practise coupling and decoupling the arms. Feedback was overwhelmingly positive, with users noting:

Improved ergonomics
Faster connection times
Greater confidence in safe operation

The benefits were not theoretical – they were immediately visible on site.

A Proven Approach for Cryogenic Transfer

LNG loading arms are engineered mechanical systems designed to safely transfer cryogenic liquids between storage and transport vessels, while maintaining control, balance and vapour management.

This project reinforces a key principle in bulk liquid handling:

The right loading system doesn’t just improve performance – it protects operators, reduces risk, and supports long-term operational efficiency.

For LNG and other cryogenic applications, where safety margins are critical and operating conditions are demanding, loading arms provide a clear advantage over traditional hose-based systems. This aligns with wider trends in cryogenic transfer, including CO₂ handling systems.

Considering a Move Away from Hoses?

If your operation is still relying on hoses for LNG or other cryogenic transfers, there is a clear opportunity to improve safety, reduce risk and increase operational efficiency.

Carbis Loadtec works with operators across road and rail loading environments to design systems that:

Improve safety and compliance
Reduce manual handling risks
Increase speed and efficiency
Deliver long-term reliability
