New Rampart Terminal/Assist Tug Series

Robert Allan (Vancouver, Canada) have developed the RAmparts Class tugs in response to increasing world-wide demand for their highly efficient ship-assist/terminal tug designs. The RAmparts Class designs address the increasing demand for compact, economical tugs with high powers, and are geared towards economical series production. These twin Z-drive, diesel-powered tugs are designed for maximum efficiency in the performance of ship-handling duties for tankers, bulk carriers and container ships in particular. The hull form and layout have evolved over several decades through the extensive experience of the designers.

The RAmparts Class tugs are of robust, all-welded steel construction, with scantlings significantly in excess of the minimums of any Classification Society. Although the basic designs are for dedicated assist tugs, working off a forward winch, design options can be readily included to outfit the tugs for tanker escort, fire-fighting, pollution response or aft towing.
The designs are based on an intended low-manning operation, with a high standard of machinery automation, but the accommodations can be adjusted to match almost any reasonable requirement. They are designed for operation in international waters, with maximum outdoor ambient air temperature to 35° Celsius and maximum sea water temperature to 32° Celsius; with system modifications required to operate in more extreme conditions.
