TRAktor Series

Model TRAktor-V (Voith), TRAktor-Z (Z-drive)

Tractor tug designs combining the former AVT and AZT series, offered with Voith Schneider (VSP) or Z-drive propulsion for harbour, terminal and escort duties.

Description

The TRAktor designation combines Robert Allan Ltd.'s previous AVT and AZT series of tractor tugs into a single series. Because function and form are so similar, the same design can be offered with either Voith Schneider Propeller (VSP) or Z-drive propulsion, with some differences in deadweight.

TRAktor-V applies to Voith-propelled tugs for harbour, offshore terminal or tanker escort duties, featuring the sponsoned hull form developed exclusively by Robert Allan Ltd. for escort performance, similar to that used on the RAstar series. TRAktor-Z applies to similar Z-drive tractor tugs with the drives forward of amidships, for the same range of duties. Tugs are classed by drive type (V or Z) and length, and can accommodate a wide range of powers and equipment.

Key features

  • Voith or Z-drive tractor propulsion
  • Sponsoned hull form for escort and seakeeping performance
  • Noted for escort performance and seakeeping capability

Applications
