Robert G. Allan on the challenge of ship-handling tug design
Marine aesthetics – defined mobility
For most trading nations, the sea is the most important route of transport for exchange of goods. More than 90 per cent of the total world trade is handled via sea routes. To enable bulky transport ships to manoeuvre in coastal waters and ports, harbour tugs are of great importance to tow the ships on the spot. The Z-Tech is a new category of harbour tugs designed by world-renowned Canadian naval architect, Mr. Robert Allan.
Robert G. Allan on “The Challenge of Ship-Handling Tug Design”:
The objective was to create a new and distinctive design that would truly represent a breakthrough in ship-handling technology, and offer improvements in performance and crew safety. Robert Allan Ltd. met with tug crews and operations managers to gain a better understanding of the complete operation and specific tug requirements in Singapore. Emerging from that session was a clear understanding that some crews had a distinct preference for the “tractor” style of tugs, while others favoured the stern-drive type, each with unique operational advantages. Our challenge was to develop a single design that would incorporate the best features and eliminate the negative characteristics of both types.
