Ramparts 2400 SX 60 / 70 / 75

The RAmparts 2400 SX tug is twin Z-drive, diesel powered tug designed for maximum efficiency in the performance of ship-handling duties for sea going ships. The hull form and layout have evolved over several years through the extensive experience of the designers at Robert Allan Ltd. working with tug owning Clients and their crews in developing truly high-performance tugs for this challenging service.

Robert Allan Ltd. have extensive experience in the custom design of high performance ASD tugs to mach Clients’ specific operational requirements. Vessels to these designs have been widely acclaimed for their overall design and particularly their maneuvering, sea-keeping and stability performance.

2400 SX model, an exclusive Sanmar design, is closest to the ASD 24/45 & ASD 24/50 design but with a 2m increase in beam over the same length. This ensures greater performance as well as stability from more powerful Caterpillar engines coupled to larger Rolls-Royce Z-drives. The new versions will give 60, 70 or 75 tons bollard pull depending on the propulsion system size selected by the customer.

This design is 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. The layout shown has been developed to match the most commonly acceptable manning standards. Optional layouts are available as either basic “day boat” or with full accommodation for a crew of up to six persons.

The RAmparts 2400 SX design code “SX” for Sanmar Exclusive which means the design has been modified by Robert Allan Ltd. to suit Sanmar Shipyards’ standard production range and optimized with the operational input from Sanmar’s tug operation department.
