JANUARY 28, 2015—Last quarter, Signet Maritime, Pascagoula, MS, took delivery of its 72 ft Azimuth Stern Drive (ASD) tug Signet Vigilant.

The ninth ASD added to Signet’s fleet in the last four years, the Signet Vigilant was built at the company’s shipyard, Signet Shipbuilding & Repair in Pascagoula, MS.  The 30-metric tonne bollard pull, EPA Tier 3 compliant, ASD tug is the first designed by Castleman Maritime, LLC, Clear Shores, TX, for Signet. She will operate from Signet’s Pascagoula Division, performing rig escort, ship assist and barge assist work.

The Signet Vigilant’s compact design allows for improved capabilities to assist marine vessels in tight quarters and shallow inland waterways.

The environmentally friendly tug will have reduced exhaust and lower fuel consumption to meet EPA Tier 3 marine emission regulations. 

Propulsion power for the 72 ft x 28 ft Signet Vigilant is supplied by two MTU 8V-4000 M54 Tier 3 engines, delivering a combined total of 2,400 bhp at 1,800 rev/min.  The engines drive two Rolls Royce US 155 P12-FP azimuth propulsion units. Electrical power is provided by two John Deere 4045AFM85 EPA Tier 3 engines coupled to 65-KW Marathon Magnaplus generators.

Deck machinery includes a Markey DEPC-32, 20 HP winch on the bow, and two Patterson WWP40E 40-ton facing winches on the stern. The hawser winch capacity is 525 feet of 6.5-inch circumference Saturn 12 synthetic line.

Captain Mark Sutera, vessel master of the newest Signet tug reports: “The Signet Vigilant exhibits strength in areas of maneuverability and size. The vessel performs multi-disciplinary work ranging from docking large tankers, drilling rigs, and ATBs, to shifting barges.  The lean dimensions allow her to maneuver in tight quarters without compromising the job.  She is outfitted with state-of-the-art navigation equipment and first-class accommodations for the captain and crew.  While working in the Port of Pascagoula, the bar pilots favor the Signet Vigilant for her strength and specific capabilities.”
