Innovative LNG-Powered Feeder Design By Technolog For Seaspan


Technolog has developed a groundbreaking LNG-powered feeder design for Seaspan, which combines elements of both the Maersk ‘house-forward’ approach and conventional mid-bridge ship design. This new vessel design, which recently received approval in principle from Lloyd’s Register (LR), aims to maximize forward visibility while maintaining crew accommodation at the aft.

Maximizing Visibility and Capacity

The 198-meter vessel design strategically splits its superstructure into two sections to enhance forward visibility, a key benefit of the bow-bridge principle. This design approach, inspired by Maersk’s methanol-powered ships, allows for higher container stack capacity by reducing the height limitations imposed by traditional mid-bridge designs. The increased capacity is crucial for navigating routes with restricted air drafts, such as under the Egyptian–Japanese Friendship Bridge over the Suez Canal.

Addressing Crew Comfort and Safety

While the bow-mounted bridge design improves container capacity and visibility, it presents challenges for crew safety and comfort. In adverse weather, bridge crews are exposed to harsher conditions, and emergencies require longer distances to reach the engine room or lifeboats. The Technolog design mitigates these issues by placing off-duty crew accommodations closer to the middle of the vessel, ensuring better comfort and quicker access during shifts.

Future-Proofing with Ammonia-Ready Design

Initially powered by LNG, the vessel design is also ‘ammonia-ready,’ aligning with future maritime fuel trends. This forward-thinking approach reflects Seaspan’s commitment to sustainable and innovative shipping solutions. The collaboration between Seaspan, LR, and Technolog demonstrates leadership in ship design, offering a creative and efficient solution for the feeder ship segment.
