Chinese yard Jiangsu Zhenjiang Shipyard has recently launched a dual fuel RAstar 3800-DF tug, designed by Robert Allan Ltd (RAL) of Canada, at its Zhenjiang facility.

The tug is being built for Ningbo Zhoushan Port Company, also from China. The vessel will be the first LNG-fuelled tug in the operator's fleet, and the 10th custom designed vessel designed by RAL for Ningbo Port.

This latest design has the following principal particulars: Length Overall: 38.00m; Beam, moulded: 13.50m; Depth, moulded (hull): 5.80m; maximum draught: 5.53m.

The new RAstar 3800-DF tug will be powered by a pair of Niigata 8L28AHX-DF dual-fuel engines, each driving a Rolls-Royce US 255 CP Z-drive, and delivering a bollard pull of about 80t. The tug will have an LNG capacity of 55m³, giving it a range of over 700 naut miles in LNG mode, and nearly 1700 naut miles in diesel mode.
