Guarding our coastlines: How Lamor's specialized booms counter the sargassum crisis

The Challenge

In recent years, the rapid accumulation of Aquatic Invasive Species (AIS) and particularly sargassum seaweed, has emerged as a major environmental and economic crisis for coastal communities worldwide. Huge, floating mats of vegetation clog waterways, disrupt local fisheries and damage vital coastal infrastructure. When these massive bio loads wash ashore, they rot on beaches, releasing foul odors that severely impact the hospitality and tourism sectors, while devastating near-shore ecosystems by blocking sunlight and depleting oxygen levels in the water.

Managing this heavy, dynamic influx of debris presents severe mechanical challenges. Standard barriers often buckle under intense water pressure or fail prematurely due to harsh marine conditions, UV exposure and the sheer weight of the accumulating vegetation.

The Solution

Drawing from engineering principles proven in demanding oil spill control environments, Lamor has designed a dedicated range of Sargassum Debris Booms explicitly optimized for containing, gathering and collecting floating nuisance vegetation. While they share structural commonalities with oil booms, Lamor’s Sargassum Booms incorporate unique design variations and material selections specifically engineered for aquatic debris management.

The Sargassum Boom is constructed from high-strength PVC coated polyester fabric, designed for durability and environmental safety. The material is UV-resistant and non-toxic, ensuring long-term performance in harsh marine and coastal environments. The fabric provides an optimal balance between flexibility and structural integrity. Depending on the environment, flotation is achieved using cost-effective foam elements, or rigid molded float pairs designed to maintain consistent buoyancy and stability across varying water conditions.

Each Sargassum Boom section is engineered with an optimal height above the water and an effective submerged depth to maximize the containment of floating vegetation. The system incorporates heavy-duty mesh panels that allow for controlled water flow while successfully capturing sargassum and other marine debris. Furthermore, the anchoring is designed for high versatility, making it suitable for both sand and rock substrates using heavy-duty galvanized steel ballast to ensure secure positioning in dynamic marine environments.

Lamor's systems feature marine grade aluminum end connectors to enable rapid deployment and modular expansion. Performance specifications include wave resistance up to one meter and a minimum capture efficiency of 80%, ensuring reliable containment in moderate sea states. The boom is engineered for durability with a minimum operational lifespan of five years with proper maintenance and storage, providing a robust and cost-effective solution for long-term sargassum management and coastal protection applications.

Our Aquatic Invasive Species containment systems represent a vital bridge between proven environmental industrial design and the challenges facing our coastal ecosystems. By adapting our world-class oil spill containment expertise into a highly durable debris boom, we are helping communities mitigate the economic impacts of sargassum seaweed. We deliver solutions that don’t just withstand severe marine environments but do so with superior efficiency and an optimized cost structure built for long-term coastal protection. - Dan Beyer, General Manager, Lamor USA

The Impact

By successfully deploying Lamor’s AIS and Sargassum Debris Booms, coastal municipal authorities, resorts and environmental management agencies can establish a reliable, proactive line of defense. 

These systems yield measurable environmental and operational benefits:

• High capture efficiency: Reaching capture efficiencies of 80% or greater, the booms consistently prevent floating debris from overwhelming vulnerable shorelines.
• Preserving local economies: Keeping beaches clear safeguards hospitality, real estate, and tourism sectors from catastrophic seasonal disruptions.
• Ecological balance: Deflecting massive bio loads away from shallow water zones prevents the localized anoxia and ecological dead-zones associated with decaying organic matter, preserving native marine life.
• Operational flexibility: Designed for versatility, the anchoring systems secure reliably across both sand and rock substrates. This flexibility makes them equally suited for rapid tactical sweeping or permanent, long-term installations to keep critical waterways clear.
