GalTex
Pilots Tug Matrix
The following guidelines have been developed
to determine adequate Tug assistance in the Ports of Texas City and Galveston. Similar docks have been grouped and coupled
with vessel size and draft information. Assist tugs are then designated by the
circumstances of the maneuver. Tugs are categorized by “bollard pull” as
provided by area operators. Bollard pull is used rather than horsepower to rate
tugs effectiveness. Additionally, the tug’s design type, tractor or
conventional, has a definite bearing on effectiveness and desirability.

As always, any vessels’ specific concerns
should be discussed with the GalTex Pilots. Ships and the waters in which they
operate represent a dynamic, ever-changing environment. Firm rules addressing
every possible scenario are not possible. The individual pilot and master on
board are best situated to evaluate the specific docking and/or undocking
evolution contemplated by the vessel and the prevailing weather, current, and
traffic situation affecting the vessel. These guidelines are recommendations
only. It is recognized that the on-scene discretion of the pilot and master
should not be hindered. The following guidelines regarding tug assistance are
in no way intended to limit, hinder, or override the on-scene discretion of the
pilot and master as they navigate vessels on the waters of Texas
City and Galveston.
We realize that there will be situations where actions that conflict with these
recommendations may be necessary to address specific or special circumstances
that confront a specific vessel. Further, it is recognized that as the demands
of maritime commerce, vessel and tug design, and terminal configuration may
change requiring a departure from the current tug assistance guidelines.
