Vigor's Seattle shipyard has delivered an ATB twin screw tug, the 'Dale R Lindsey', to Harley Marine Services.
The 2,200kW tug is 29 metres long with a beam of 11.5 metres.
Designed by Elliot Bay Design Group for operations in Alaska, the ATB tug uses an Articouple FRM-43M coupler system to pair with the 20,000 barrel oil barge, 'Petro Mariner'.
It features a raised aluminium pilothouse for improved visibility, built by Kvichak.
