Fleet information

What is a tank container?

Tank containers are versatile and robust vessels used for transporting a wide range of hazardous and non-hazardous cargoes, including chemicals, petrochemicals, food-grade products, gases, and powders. They are designed to ensure safety, maintain product purity, and support intermodal transport across trucks, trains, and ships.

Key features include:
  • Durable Design: Built with stainless steel pressure vessels within ISO-standard frames (20' x 8' x 8.5').
  • Wide Capacity Range: Typical capacities range from 15,000 to 26,000 litres.
  • Safety & Compliance: Adhering to international standards for maximum protection of people and products.

M&S Logistics offers a fleet of liquid ISO tank containers and gas tank containers, providing a dependable and clean solution for bulk liquid transportation.

Baffle ISO Tanks for Safe & Flexible Liquid Transport

"Sloshing" refers to the movement of liquid cargo inside a tank during transport, which can be intensified by braking or cornering. To minimize these effects, Baffle ISO tanks feature three internal anti-surge baffles, enhancing stability and safety. With a 26,000-liter capacity, these tanks comply with hazardous material transport regulations, allowing for partial discharges at multiple locations.

Baffle ISO tanks accommodate various liquid densities while ensuring smooth product flow, similar to standard ISO tanks. Their design includes three 300mm cleaning hatches and a 500mm central manlid, enabling thorough post-discharge cleaning. Additionally, full walkway access ensures safe inspection and maintenance.

These tanks offer flexibility for different product densities but are not recommended for resins, latex, or emulsions due to extensive cleaning requirements. With enhanced stability, compliance, and cleaning efficiency, Baffle ISO tanks provide an optimal solution for transporting liquid cargo while reducing the risks associated with sloshing.

Loading and Discharge Procedures

M&S Logistics ensures the safe and efficient handling of tank containers with comprehensive procedures for loading, discharge, and steam heating, prioritising safety, compliance, and product integrity.

Key Procedures:
LOADING:
  • Ensure tanks are clean, empty, and suitable for cargo.
  • Use closed-loop systems for hazardous vapors and maintain proper ullage.
  • Verify customs seals, labeling, and documentation before transport.
DISCHARGE:
  • Follow safety measures, including earthing and secure connections.
  • Utilize gravity, pressure, or pump discharge methods based on cargo compatibility.
  • Clean, seal, and label tanks after discharge.
STEAM HEATING:
  • Use steam channels carefully to avoid exceeding pressure or temperature limits.
  • Gradually increase steam pressure with proper monitoring.
  • Ensure cargo is fully melted before discharge.
SAFETY FIRST:
  • Adhere to working pressure and temperature limits.
  • Implement proper safety measures during all operations.

M&S Logistics' procedures ensure regulatory compliance, cargo protection, and operational efficiency. Watch the video below for more details on loading and discharge processes.

Specific Gravity & Filling Ratio Guidelines

Specific Gravity (SG) is the ratio of a substance’s density to that of water at a given temperature, aiding in product identification and handling. With water having an SG of 1 at 4°C, this property helps determine whether a substance will sink or float. For more information on specific gravities, view our Example Products.

When transporting hazardous materials in ISO tank containers, filling ratios are crucial for safety and compliance with international regulations (ADR/IMDG). The minimum fill is typically 80%, but may be as low as 20% in specific cases. Ullage space is also required to allow for product expansion. Liquid movement within partially filled tanks can create dangerous surging, with levels of 40%-60% leading to extremely unstable conditions. For hazardous products, deviations require tanks with baffles or surge plates. Adhere to these guidelines to ensure safety and compliance. Contact us for further product-specific advice.
