HD Hyundai Delivers World’s First Lashing-Free Container Ship, Redefining Deck Cargo Security

HD Hyundai has delivered the world's first container ship featuring a hybrid lashing-free system, eliminating the need for manual lashing on deck. The vessel, built for a French shipping company, utilizes extended cell guides and a portable bench system to enhance automation potential while increasing payload capacity by over 10%.

HD Hyundai Heavy Industries has officially delivered the world’s first container ship equipped with a hybrid "Lashing-Free" system, marking a significant departure from traditional cargo securing methods. Delivered in early October for a French shipping client, the 13,000-TEU (twenty-foot equivalent unit) vessel integrates proprietary engineering that removes the necessity for crew members to manually secure containers stacked on the open deck. This development, jointly executed by HD Hyundai Heavy Industries for technology and structural validation and HD Hyundai Samho for detailed design and construction, addresses long-standing safety and efficiency challenges in maritime logistics.

The core innovation lies in how the vessel manages containers outside the internal cargo hold. Traditionally, large hatch covers obstruct the vertical alignment of cell guides—steel structures that guide containers into place within the hold. To resolve this, HD Hyundai developed a standardized "portable bench." This component is installed between the cell guides and extends above deck. Engineered to the exact dimensions of a standard 40-foot container, the bench can be handled by conventional port cranes, seamlessly integrating into existing terminal operations. Unlike static structures, these benches are removable, allowing flexibility in cargo configuration while providing a stable platform for upper-deck loads.

Complementing the portable bench is the Twistlock Rooting System, a technology designed to securely fasten containers stowed outside the cell guide area directly to the vessel’s primary structure. Conventional vessels rely on temporary lashing rods and braces, a process that is labor-intensive and hazardous. The Twistlock system effectively anchors containers as if they were rooted to the hull, providing rigid support against the dynamic forces of rough seas and high winds. This mechanical integration not only stabilizes the cargo but also unlocks additional structural capacity. According to performance metrics from sea trials conducted in September, the system allows the vessel to carry over 10% more cargo weight on deck compared to conventionally equipped ships of similar tonnage. Furthermore, the trials indicated a significant reduction in operational vibration, a common issue with traditional lashing bridges and hatch cover arrangements.

The implications for maritime automation are immediate. By removing the requirement for manual lashing operations on the exposed deck, the vessel creates a safer environment for future unmanned or remote-controlled port terminals. The ability to handle the portable bench via standard crane infrastructure ensures that the technology does not require specialized handling equipment, easing its adoption across the global logistics network. HD Hyundai notes that the technology was previously showcased at the International Maritime Organization’s Sub-Committee on Carriage of Cargoes and Containers in 2024 as a key measure for preventing container loss at sea, highlighting its relevance to international safety standards.

Security against cargo loss also translates to environmental protection. Secured containers are less likely to shift or fall overboard during transit, reducing the risk of marine pollution caused by lost cargo or damaged containment units. The company holds multiple intellectual property registrations for these technologies globally and recently received the IR52 Jang Young-shil Award for the innovation. As HD Hyundai expands this concept toward smaller and medium-sized vessels, the industry may see a gradual shift toward fully integrated, automated cargo management systems that prioritize both load efficiency and operational safety.
