    New unit delivered to Signet

    Vessel & ROV News // June 17, 2014

    Adding to its fleet of 37 conventional and azimuth stern drive (ASD) vessels, Signet Maritime Corporation has taken delivery of its ninth newly constructed tractor tug in six years.

    Signet Acturus is a 105ft x 38ft Z-Drive, designed by Robert Allan Ltd of Vancouver, British Columbia and was delivered by Patti Marine Enterprises of Pensacola, Florida in May 2014.

    Signet Arcturus is powered by two Caterpillar model C175-16 main engines, each rated 3,417 bhp at 1,800 rpm. The engines are coupled to two Rolls-Royce US 255 CP azimuth thrusters via carbon fibre shafting, providing thrust for ABS certified sustained bollard pull of 83.45 metric tonnes. All Caterpillar mains and John Deere 6068TFM76 generator engines aboard the vessel are US EPA Tier 3 certified for reduced emissions.

    Joseph W Dahl, Vice President, Signet Maritime said “this technologically advanced newbuild complements Signet’s offshore towing, rig escort and subsea expansion.”

    The new unit will be joined by her sister, Signet Polaris, a second ocean towing tractor tug, scheduled for delivery later this month from Patti Marine. Both tugs will be based at Signet’s Ocean Towing Division in Port Fourchon, Louisiana for service to the offshore energy industry.
