Eastern delivers RApport 2400 z-drive to Bisso Offshore


The following is text of a news release from Eastern Shipbuilding Group:

(PANAMA CITY, Fla.) — Eastern Shipbuilding Group has announced delivery of the first of two 80-foot, 5,100-hp z-drive tugs, C.D. White for Bisso Offshore LLC, a division of E.N. Bisso & Son. The vessel has 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).

C.D. White is a RApport 2400 z-drive ship-handling tug design provided by Robert Allan Ltd. of Vancouver, British Columbia. The sister vessel, A. Thomas Higgins, is under construction at Eastern’s Allanton, Fla., facility.

E.N. Bisso is one of Eastern’s long-term valued customers and has taken delivery of four previous z-drive ship assist tugs from the shipyard starting in 2007. These two new Robert Allan RApport 2400 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.

The tug is named after Cornelius Dee “Jack” White Jr. He was an owner of E.N. Bisso and was married to the company’s then president, Beverly Bisso White. He was instrumental in the management and growth of the company in its early days. It is the second boat to be named for Jack White in recognition of his place in the company’s history.
