Seaboard Marine invests in electric LHM 550s for U.S. trade hubs

Liebherr delivers three LHM 550 mobile harbour cranes with electric drive, tower extension, and custom pads to enhance container and multipurpose handling at PortMiami and Port of Houston
Seaboard Marine Ltd., established in 1983, operates a fleet of over 20 vessels and over 60,000 containers, serving nearly 40 ports and carrying more cargo to and from PortMiami than any other carrier
The project builds on a partnership dating back to 2001, adding to 8 Liebherr cranes already in service and reinforcing Seaboard Marine’s commitment to future‑ready infrastructure and operational resilience

Seaboard Marine’s decision for three LHM 550 reflects a commitment to scalable infrastructure and energy‑efficient solutions, leveraging Liebherr’s modular crane design and full‑service support to optimise performance in high‑volume environments.

Driving efficiency across two critical U.S. gateways for trade within the Americas. The three Liebherr LHM 550 mobile harbour cranes in high-rise configuration will be deployed across Seaboard Marine’s private terminals at PortMiami and Port of Houston, enhancing container handling. Electric drive positions the cranes for future shore power initiatives, while hydrostatic drive technology ensures smooth, efficient performance under variable load conditions. With an outreach of up to 54 metres and a configured lifting capacity of 104 metric tons, the LHM 550 accommodates New‑Panamax vessels while preserving exceptional turnaround times.

Boosting operational capacity at key U.S. trade hubs

PortMiami processed over 1.1 million TEUs in 2024, with Seaboard Marine as the largest carrier by cargo volume at the port. The new cranes will strengthen berth productivity and support growth in refrigerated cargo and breakbulk shipments, complementing Seaboard Marine’s LNG‑powered fleet expansion. These cranes will also enable fast vessel turnaround, reducing congestion during peak periods and supporting the port’s role as a hub for Caribbean and Latin American trade.

At the Port of Houston, which achieved a record by handling more than 4.1 million TEUs last year, the additional crane capacity will improve flexibility for container handling while supporting Seaboard Marine’s multipurpose service model. This expansion strengthens the company’s strategy to uphold competitive transit times and address the rising demand for container handling.

Engineering precision and long-term service assurance

Customer‑specific adaptations, including tower extensions, customised supporting pads, and tailored painting, reflect operational and branding requirements. Each crane is equipped with electric drive, ensuring eco‑friendly operation and compliance with future port electrification standards. This delivery continues a partnership with Seaboard Marine that has spanned more than two decades, reinforcing trust through consistent technical performance and tailored solutions.

Liebherr’s regional service network, supported by Liebherr USA, Co., provides remote support and rapid on‑site intervention under a full‑service contract, with dedicated teams based in Miami and Houston to guarantee swift response and maximum uptime. ‘This collaboration demonstrates our shared commitment to future‑ready solutions and operational excellence,’ said Andreas Ritschel, General Manager Sales Mobile Harbour Cranes at Liebherr‑Rostock GmbH. Beyond technical delivery, Liebherr offers operator training programmes and digital support tools such as LiDAT smartApp for continuous performance monitoring, helping Seaboard Marine optimise crane utilisation and safety standards.

Looking ahead, the partnership positions Seaboard Marine to meet rising trade volumes and sustainability targets with confidence, leveraging equipment engineered for durability and adaptability in dynamic port environments.
