tug boats
Using the latest technology and
design methods, EBDG has designed, detailed and supervised the
construction of some of the industry's most innovative and
efficiently operating tugboats.
Unlike other firms, we do not
create a generic design and sell it to the industry. We work with
operators to design to their specific needs. Today's multiple
service operating environments, such as towing, escort and fire
fighting capabilities, demand a more comprehensive approach to
designing a primary service vessel. Model tank tests of hull form
efficiency and 3-D computer modeling to assure clearances and avoid
interference (before construction), are just two examples of the
advances in design technology available to tugboat owners and
operators. From designing and testing hull forms for optimum
efficiency to determining the most appropriate propulsion systems
for your service requirements, our engineering team will work with
you to meet your operational needs. Comprehensive owner's
representation during construction - from the first cut of steel
through the final coat of paint - will help ensure that your tug is
built as ordered.
Green Tug Technology
As concerns about global warming and the impact of modern society on
the environment continue to be debated, the marine industry has an
opportunity to demonstrate its commitment to responsible stewardship
of the waters and coastlines that we travel.
EBDG President John Waterhouse has
been investigating one aspect of the marine industry, ship assist
tugs that are in every port city. These vessels have a unique
operating profile that lends itself to more efficient propulsion
technologies and hence opportunities for reducing engine emissions.
Beyond improving the propulsion plant, there is also opportunity for
use of recycled materials, selection of low-energy equipment, use of
environmentally-friendly operating practices, and design for
ultimate vessel disposal.
Mr. Waterhouse believes that the
environmentally-friendly design principles might apply to a wide
range of vessel types and recently authored a paper in which he
discusses the possibility that the shipping industry adopt an
environmental certification program for vessels similar to those
certification programs for buildings that have been developed in the
U.S. and Europe.
EBDG and its predecessor firm have
designed over 50 different tugboats, ranging from small harbor tugs
to large deep sea salvage tugs. Some of EBDG's recent tug efforts
include the following projects:
- Contract Design and structural
lofting package for a 76' shallow-draft, triple-screw towboat
for Yutana
- Concept design of a new 126'
ocean tug for a West Coast tug and barge operator
- Design support for two new
Ship Docking Modules for REYSER Remolcadores Y Servicios
Maritimos, S. L., Barcelona, Spain
- Design of a new low-emission
SDM for Seabulk International
- Plan review for 3 tugs being
for Seabulk International
