Avondale shipyard in New Orleans, La.
Phillips Petroleum Company, parent of
Polar Tankers, is building five Endeav-
our Class tankers. The contract cost of
the Polar Discovery is valued at $168
million.
The Endeavour Class tankers, also
known as the Millennium Class, are the
first crude-oil carriers being built for the
Alaska trade in compliance with the fed-
eral Oil Pollution Act of 1990. The first
tanker, the Polar Endeavour, arrived in
Valdez, Alaska, on its maiden voyage in
July 2001.
The new Polar Discovery tanker will
join the Polar Tankers fleet in 2003. and
Polar Resolution will enter the Alaska
trade this summer. Polar Adventure will
be delivered in late 2004, followed by
the fifth ship, the Polar Enterprise, in
2005.
NGSS Avondale Operations currently
has four 140,000-swt crude oil carriers
under construction for Polar Tankers.
The Endeavour Class tankers are
being built to meet and/or exceed exist-
ing and proposed environmental regula-
tions and are setting new standards for
innovation and environmental protec-
tion. They were designed specifically
for the transport of crude oil from
Valdez, Alaska, to the West Coast of the
United States, through some of the most
severe trade routes in the world. The
ships also will deliver cargo to Hawaii.

or void spaces. The vessels also will
meet pending regulations for air emis-
sions from engines, and are painted with
tin-free anti-fouling paint in deference
to proposed regulations.
Polar Discovery and its four sister ves-
sels measure 895 x 152 x 86 ft. (272.6 x
46.2 x 26.3 m), and are powered by twin
11,060 kW (15,000 bhp) slow speed
diesel engines. The ships have a 2,206
kW (3,000 hp) bow thruster, and can
move at 16.6 knots loaded and 16.9
knots in ballast. The carriers will hold
just over one million barrels of cargo at
maximum capacity, and will be
equipped with the latest electronics to
ensure safe and efficient operation.

To the right of that familiar timber
pile is the first genuine innovation
in piling construction in decades: the
SEAPILE® Composite Marine Piling.
Whether it is used for fender piling
or light structural piling, SEAPILE
provides a durable, environmentally
friendly alternative to creosoted or
chemically treated timber.
SEAPILE is made from
DURALIN®plastic, a matrix of 100%
recycled resin that bonds with the
pile's fiberglass reinforcing elements.
Impervious to marine borers, SEAPILE
is also resistant to ultraviolet light,
chipping and spalling. It is currently
available in 10 inch (250mm), 13 inch
(330mm) and 16 inch (400mm)
diameters, with lengths of up to
90 feet (27m). The SEAPILE drives
just like a wood pile with the
same machinery.
So make sure your next piling
purchase is truly beyond compare.

Piling from Seaward International.
