Hvide Signs $6 M Deal With Halter
Marine Te Build New Design
Hvide Marine Inc. signed a contract with the
Halter Marine Group, Inc. for the construction of
two Ship Docking Modules (SDM) for delivery in
early 1998. The SDM is a double-ended ship-dock-
ing vessel representing the next generation of har-
bor tugs.
The company has filed a patent application on the
design of the SDM.
"This is the first major breakthrough in tugboat
design in nearly 100 years," said Erik Hvide,
chairman, president and CEO. "The SDM's round-
ed shape and twin Z-drives give it unmatched
maneuverability and power, making it the safest
and most cost-efficient ship-docking vessel in the
world. It's the first vessel capable of generating 100
percent of its bollard pull in any direction — for-
ward, backward and sideways. It's so different
from a conventional tug that we had to give it a new
name," he added.
The contract with Halter provides for the con-
struction of two SDMs at a cost of approximately $3
million per vessel. Including certain owner-fur-
nished equipment, professional fees and contingen-
cies, the total cost of each vessel is approximately
$4.75 million. The contract also contains options
for four additional vessels. When placed in service,
the first two SDMs will operate in Port Everglades,
Fla., and Mobile, Ala., allowing the continued
deployment of two of the company's existing tugs in
the offshore sector.
"We're delighted Hvide chose Halter to build these
truly unique tug," said Halter CEO John Dane III
after the contract award.
The 4,000-hp SDM will have Z-drives mounted
forward and aft and offset from center, providing
equal propulsion in all directions. It has been
designed to operate with two crew members, thus
reducing operating costs below the level main-
tained by conventional tugs. The SDM measures
76 ft. (23 m) long, with a 50-ft. (15-m) beam.
Elliott Bay Design Group began the concept
design of the SDM in early 1995. Several designs
were prepared during the evolution of the SDM,
and Elliott Bay's James Cole said that the accep-
tance or rejection of design features brought unique
design challenges. Construction of a radio-con-
trolled working model was authorized in October
1995, and model tests were conducted secretly in
the Seattle marina in March and April 1996.
