Svitzer Expands Fleet with Six New Cheoy Lee TRAnsverse Tugs

When a global towage operator doubles down on a specialized design, port captains and fleet managers take notice. Svitzer has committed to a fresh build program for six additional 29-metre TRAnsverse tugs, partnering once again with Cheoy Lee Shipyards for the construction phase according to Maritime Executive Regs. This follow-up order signals a clear shift in how major harbor towage providers view maneuverability and bollard pull performance in congested terminal environments.

For harbor masters and terminal operators handling ultra-large container vessels (ULCVs) and massive gas carriers, the physical dynamics of towage are changing fast. Traditional stern-first escort limitations often create bottlenecks in restricted waterways, increasing time in port and driving up demurrage risks for charterers. The TRAnsverse tug layout, engineered by Robert Allan Ltd, introduces a distinctive propulsion and staple configuration that allows vessels to pull sideways with significantly higher efficiency than conventional azimuthing stern drive (ASD) units.

Why Svitzer is investing in transverse tugs

Svitzer is scaling up its deployment of TRAnsverse tugs to address the growing safety and efficiency demands of shipowners operating mega-vessels in tight port restrictions. By ordering six more 29-metre units from Cheoy Lee Shipyards, Svitzer aims to replace older azimuthing stern drive assets and provide superior indirect steering forces during high-speed harbor transits. Port operators face tighter clearance windows, meaning harbor tugs must deliver maximum bollard pull and omnidirectional responsiveness without risking propeller wash damage to quay walls or moored ships. These advanced 29-metre vessels allow pilots to execute complex berthing maneuvers with fewer assets on station, reducing overall port costs and mitigating collision risks during adverse weather conditions. Fleet managers evaluating newbuilding programs are closely monitoring how these operational efficiencies translate into lower P&I claims and reduced fuel consumption during continuous harbour cycles.

The physical footprint of these tugs is optimized for dense terminal layouts where turning basins are restricted. The central positioning of the propulsion units alters the pivot point of the hull entirely.

• Enhanced sideways pulling capacity improves escort stability during high-speed maneuvers.
• Optimized hull geometry reduces turbulent water flow under heavy bollard pull loads.
• Standardized 29-metre framing streamlines crew familiarization across multiple regional hubs.
• Advanced towing winches minimize snap-load risks during dynamic line-handling operations.

What does this mean for Cheoy Lee Shipyards?

Cheoy Lee Shipyards is solidifying its orderbook through repeat contracts for complex, high-specification harbor craft like the 29-metre TRAnsverse tug series commissioned by Svitzer. Building these sophisticated Robert Allan-designed vessels requires precise yard capabilities, strict adherence to class society rules, and reliable supply chain management for propulsion and automation systems. As global emissions regulations tighten under IMO frameworks, shipyards capable of delivering efficient, multi-role tugs with optimized hull forms are capturing premium commercial business from major marine service providers. This partnership demonstrates how established builders can secure long-term revenue streams by aligning with operators who are actively modernizing their fleets for lower-emission, high-agility operations.

"The continuous rollout of specialized vessel classes highlights an industry-wide pivot toward assets that can handle extreme maneuverability challenges in constrained port geometries."

What to watch next

Fleet managers and port operators should monitor three key indicators as this new generation of towage assets moves from the shipyard to active commercial deployment:

First, watch for delivery schedules and initial deployment ports announced by Svitzer for the newly contracted 29-metre hulls. Second, track any Class Society updates or performance benchmarks regarding the fuel efficiency and emissions output of these units during active harbour duties compared to legacy ASD tugs. Third, observe whether competing towage providers begin placing counter-orders for similar omnidirectional designs to maintain competitive parity in major global container hubs.
