Eastern delivers second z-drive this year to Bisso


From Eastern Shipbuilding Group:

(PANAMA CITY, Fla.) — Eastern Shipbuilding Group has delivered the second of two 80-foot, 5,100-hp z-drive tugs, A. Thomas Higgins, for Bisso Offshore LLC, a division of E.N. Bisso & Son Inc. of New Orleans. The vessel completed its bollard pull testing witnessed by the American Bureau of Shipping (ABS) and received its U.S. Coast Guard Subchapter M certificate of inspection (COI).

A. Thomas Higgins is a RApport 2400 ship-handling tug design provided by Robert Allan Ltd. of Vancouver, British Columbia. A sister vessel, C.D. White, was delivered in January and is currently working in New Orleans.

E.N. Bisso has taken delivery of five modern z-drive ship-assist tugs from Eastern starting in 2007. These two new RApport 2400 design tugs have been customized by the designer, the builder, and owner to provide specific operational features including a high bollard pull forward and aft, enhanced maneuverability and escort performance, better fuel economy, crew comfort, safety under the new Subchapter M requirements and reduced emissions meeting the new EPA Tier 4 emissions regulations.
