Guatemala’s Puerto Quetzal Welcomes a Greener Towage Solution

SAAM Towage will deploy the SAAM Hunabku, Guatemala’s first IMO Tier III-compliant tugboat, at Puerto Quetzal as part of its fleet renewal program in the Americas. The vessel, built by Sanmar Shipyards in Türkiye, marks a significant step in reducing nitrogen oxide (NOx) emissions in the region.

A Milestone for Sustainability and Operational Excellence

The SAAM Hunabku, a Boğaçay-class tug based on Robert Allan’s RAmparts 2400SX-MKII design, combines compact dimensions (24.4 meters in length, 12 meters in beam) with high operational capacity. It features two CAT 3516E engines, over 80 metric tons of bollard pull, a FiFi-1 fire-fighting system, and dual azimuth propulsion. The vessel can accommodate a crew of seven and reach speeds of up to 12.5 knots.

Pablo Cáceres, SAAM Towage’s Manager of Innovation and New Construction, emphasized the vessel’s role in advancing the company’s sustainability strategy. “The SAAM Hunabku will enable more environmentally friendly operations at Puerto Quetzal,” he stated, highlighting its alignment with IMO Tier III standards, which represent the highest international benchmarks for NOx emissions control.

Rüchan Çivgin, Commercial Director of Sanmar Shipyards, underscored the shared commitment to innovation and sustainable towing solutions. “This delivery reflects our joint dedication to operational excellence and meeting the needs of modern ports,” he said.

Why It Matters for the Maritime Industry

The introduction of the SAAM Hunabku reinforces SAAM Towage’s position as a leader in sustainable maritime operations. With a fleet of over 200 tugs across 90 ports in 12 countries, SAAM continues to expand its environmentally responsible offerings. Sanmar Shipyards, with 50 years of expertise, remains a key partner in delivering high-performance, eco-friendly vessels.

The IMO Tier III certification ensures compliance with stringent emissions regulations, aligning with global efforts to reduce the maritime industry’s environmental footprint.
