Innovative Cold Chain Technologies Enable Safe Maritime Transport of Temperature-Sensitive Pharmaceuticals by Teva and Kuehne+Nagel

The Role of Cold Chain Technologies in Maritime Pharmaceutical Shipping

Ensuring the integrity of temperature-sensitive pharmaceutical products during long maritime voyages has traditionally been a logistical headache. However, the collaboration between Cold Chain Technologies (CCT), Teva Pharmaceuticals, and Kuehne+Nagel has proven maritime shipping to be a viable and cost-effective alternative to air freight, especially on demanding routes stretching from Germany all the way to Australia.

From Traditional Thermal Covers to Advanced PCM Blankets

Initially, transportation relied on a combination of active refrigerated containers supported by standard thermal covers. Yet, over recent years, incidents such as power outages at sea posed serious risks. This pushed the partnership to seek enhanced protection beyond conventional methods. Their solution? The innovative Enshield thermal blanket, a reusable high-performance passive insulation layer that incorporates phase change material (PCM) technology.

This blanket is designed to keep cargo temperatures between 2 and 8 °C — a critical band for many pharmaceuticals. Unlike traditional blankets, where hot air can become trapped and jeopardize temperature stability, Enshield’s PCM gel stabilizes temperature by absorbing or releasing heat, thus slowing temperature changes for sustained equilibrium. Its gel, Koolit Advanced, does not leak and stays solid, allowing for flexible wrapping that snugly fits pallets for maximum protection.

Rigorous Live Testing on a Challenging Route

A live trial replaced virtual simulations to robustly validate the cold chain method on one of the world’s harshest maritime shipping routes. Navigating from Germany to Australia, the shipment faced intense seasonal and temperature fluctuations that would typically threaten product quality.

The test included a deliberately complex journey: the vessel had to divert around the Cape of Good Hope due to the temporary closure of the Suez Canal, extending travel time by a week. Additionally, an unexpected electricity blackout occurred in the Indian Ocean, complicating temperature management further. Upon arrival in Sydney, delays at port—caused by minimal crew on an Australian public holiday—resulted in an extra four days of exposure to near 40 °C ambient temperatures.

Outcome: Temperature Integrity Maintained Against All Odds

Thanks to the engineered PCM blanket and strategic packaging, the shipment arrived intact despite every possible logistical glitch thrown their way. Temperature loggers recorded just minor peaks during power loss and port delays, all within safe compliance margins required for pharmaceutical safety and efficacy.

Why This Matters for Global Logistics

Maritime shipping that keeps sensitive cargo within strict temperature limits can revolutionize freight forwarding for pharmaceuticals and other perishable goods worldwide. It presents a more affordable, sustainable, and less carbon-intensive alternative compared to air freight, especially on long trade routes.

For companies managing international product distribution, relying solely on air freight can be a costly affair that adds significant price pressure. The proven success of cold chain maritime solutions like Cold Chain Technologies’ Enshield opens new doors, making sea transport a serious contender for high-value shipments.

Challenges Overcome by Innovation

• Power interruptions compromising active refrigeration
• Seasonal and climatic extremes encountered on ocean voyages
• Unforeseen port delays with exposure to high ambient temperatures

Overcoming these hurdles calls for clever use of passive thermal control layered atop active refrigeration. This combined approach secures the cold chain end-to-end, regardless of delays or detours.

Implications for the Future of Freight and Logistics

As demand grows for international deliveries of fragile medicines and biologics, cold chain maritime shipping stands to reshape logistics strategies globally. By reducing reliance on air transport, companies can cut costs, lower environmental impact, and better navigate logistical risks. Forwarders and shippers alike can benefit from integrating such technologies into their supply chain, ensuring quality doesn’t slip through the cracks.
