Hayden Grace:

Now in service in Galveston, Texas, with Bay-Houston Towing Company, the Hayden Grace is the first in a series of three Robert Alan Ltd. RApport 2600 tugs ordered by the company at Master Boat Builders Inc., Coden, Ala. (Read page 22 for more info on other tug projects underway).

Robert Allan says the vessel takes some design cues from previously completed Z-Tech tugs designed by the firm.

Main features of the vessel include compact size and shallow draft allowing it to operate in more confined waterways than previous Z-Tech vessels, as well as a specially styled deckhouse.

The customized general layout of the tug represents more than a decade of cooperation by the naval architect firm and the owners.

The master’s and chief engineer’s cabin, along with the galley and mess,

are located on the main deck, while two cabins for four crew members are located on the lower deck.

The main propulsion power for the tug is delivered by a pair of Caterpillar 3512E, EPA Tier 4 certified diesel engines, each rated at 2,213 bhp at 1,600 rpm, and driving a Schottel SRP 430FP Z-drive unit to give the vessel a freerunning speed, ahead of 12.5 knots and a bollard pull ahead of 52.5 tonnes.

The electrical plant consists of two identical John Deere 4045AFM85 diesel gensets, each with a power output of 99 ekW 480V, 3-Phase, 60 Hz.

Ship-handling fenders at the bow consist of one tier of 36- OD by 18-inch ID cylindrical fender at the main deck level; a 20- by 18-inch W-fender below the cylindrical fender and along the sheer lines of the main deck; and 18OD by 9-inch ID cylindrical fendering at the stern.
