Signet Maritime Corp., Ingleside, Texas, took delivery in July of the Robert Allan Ltd.-designed AZ 25/60-class towing and escort tug, Signet Magic.
Built at the company’s yard, Signet Shipbuilding & Repair in Pascagoula, Miss., the tug was specifically designed to work under limited maneuvering conditions. The 80’×36’×13’2″ ASD tug will be used at multiple Gulf of Mexico ports for harbor assist, and ship and rig escort.
“Our Pascagoula shipyard stepped up and worked hard as a team to deliver this vessel in 10 months to meet our customer’s needs to be on the job by August,” said Joseph W. Dahl, general manager, new construction, at Signet Shipbuilding. “This 80-foot vessel will allow us to work in tight spots when assisting movement around rigs under construction in the Ingleside [Texas] port.”
Main propulsion comes from two Caterpillar 3516C HD Tier 3 diesel engines, producing 2,575 hp at 1,600 rpm each. The Cats connect to twin Rolls-Royce US 205-FP 2,400-mm dia., 4-bladed Z-drives. The new tug has a running speed of 13.5 knots and a bollard pull of 61.4 metric tons.
Twin John Deere 6068AFM85 Tier 3-powered gensets, producing 125 kW of electrical power each, take care of the tug’s service power needs.
“The new Signet Magic is a highly versatile and maneuverable vessel that can perform multiple tasks from rig work to ship escorting, including indirect towing,” said Capt. Grant Taylor, the Magic’s master.
The Rolls-Royce package includes steering system and controls, and the electronics suite features JRC technology.
Capacities include 26,977 gals. of fuel; 7,427 gals. potable water; 344 gals. lube oil; and 87 gals. hydraulic oil.
There are accommodations for a crew of five in three staterooms.
The wheelhouse features an electronic chart display, log desk and controls, navigation aids and a 360° sliding pilot chair.
The tug will operate under Signet’s ABS-certified International Safety Management (ISM) and ISO 9001-2008 Quality Management Systems.
Signet’s construction program is on schedule with three additional tractor tugs for coastal and offshore towing to be delivered in the first and second quarters of 2014. The tug fleet’s average age is just 6.5 years.
