Robert Allan Ltd. Completes Pushboat Design for Hermasa

Innovative RApide 3000-Z2 Pushboat design specifically for the challenging operating conditions of the Madeira River system in the Amazon region.

Robert Allan Ltd. has successfully completed the RApide 3000-Z2 pushboat design for long-standing client Hermasa, delivering an innovative solution engineered specifically for the demanding conditions of the Madeira River system. Construction is now underway on two of these next-generation vessels, which are set to significantly boost high-capacity grain transportation across the Amazon region.

A key differentiator of these vessels is their ability to operate on B100 biodiesel as well as conventional marine diesel oil, reinforcing Hermasa’s commitment to sustainability and reducing environmental impact.

The RApide 3000-Z2 pushboats are designed for shallow-draft operation, enabling safe and efficient navigation throughout the Amazon River basin. When completed, each vessel will be capable of pushing up to 20 barges with a combined cargo capacity of 32,000 metric tonnes, supporting Hermasa’s commitment to sustainable, high-volume logistics.

Robert Allan Ltd. RApide 3000-Z2 Pushboat Specifications

  • Length overall: 30 metres
  • Breadth, moulded: 12 metres
  • Depth, moulded: 3.2 metres
  • Draft, navigational: 2.3 metres
  • Crew accommodation for up to 10 personnel

The vessels are designed to Brazilian Flag Rules (NORMAM-202) and will be certified as inland navigating vessels by the American Bureau of Shipping (ABS) under the Class Notation:

  • A1 River Service, Towing Vessel, AMS

The propulsion system of the RApide 3000-Z2 pushboat comprises a pair of Kongsberg US155 P14 Z-drive units, each powered by Wartsila 6L20 medium-speed marine diesel engines rated at 1150 kW. To align with Hermasa’s sustainable objectives, the engines are capable of operation with either B100 biodiesel or marine diesel oil. The Z-drives are fully with-drawable afloat and feature 1800 mm fixed pitch propellers for optimal manoeuvrability and efficiency in shallow water. Electrical power is supplied by two MWM diesel generator sets, ensuring redundancy and reliable operation for all onboard systems.
