MacGregor has introduced its new Balanced Lashing System, aimed at addressing the persistent issue of uneven load distribution in container ship lashings. Traditionally, upper lashings endure most of the stress while lower lashings operate at only half their safe capacity. The new system utilizes proven elastic elements, similar to those used in hatch cover bearing pads, to ensure even force distribution across the lashing system.
Key benefits for shipowners include increased payload capacity, allowing up to 10% more cargo on deck by balancing component stress. The system also enhances safety by minimizing the risk of broken container corners and lashing bar failures, as it eliminates peak loads on upper turnbuckles. Additionally, the integrated elastic elements function as shock absorbers, mitigating vertical impact forces during rough sea conditions.
The upgrade is straightforward for existing vessels, requiring no hot work—operators simply need to replace the upper turnbuckle. Magnus Sjöberg, Executive Vice President of MacGregor, emphasizes that the Balanced Lashing System effectively combines safety and capacity, facilitating a more intuitive lashing process while boosting earning potential.
Having undergone two years of successful testing, the system is now commercially available for container ships over 5,000 TEU with external lashing systems, and has received approvals from Det Norske Veritas (DNV) and American Bureau of Shipping (ABS).
