Great Ships of 2004
Name Alaskan Frontier Type DH Oil Tanker Owner BP Oil Shipping Co.
Builder NASSCO National Steel and Shipbuilding Company delivered the Alaskan Frontier, the first of four Alaska-class double-hull oil tankers being built for BP Oil Shipping Company, USA. These state-of-the-art ships are designed to be and touted by the builder and owner as the most environmentally friendly oil tankers ever built. The Alaskan Frontier's double hull has been designed for a life of 35 years and the deck structure has a life of 50 years, a robust configuration that is designed to perform at peak efficiency for decades in the rigors of the Gulf of Alaska's waters.
The diesel-electric propulsion system, with redundant engines, shafts and screws, significantly increases reliability and reduces air emissions and maintenance downtime. The ships also use seawater instead of oil to cool and lubricate their propeller shafts, thus eliminating the possibility of accidental oil leaks.
The ship's cargo piping, normally installed on the deck, is inside the cargo tanks to reduce the risk of small spills.
"NASSCO was acquired by General Dynamics in 1998 and they have invested more than $120 million since then to improve our shipbuilding technologies and production efficiencies," said Richard Vortmann, NASSCO president.
"BP is the first customer to fully benefit from this investment, and we are extremely proud of the ship we are delivering." The double-hull ships measure 941 x 164 ft. (287 x 50 m) and have a capacity of 1.3 million barrels of oil. The design of the tankers in the Alaska Class allows maximum flexibility for oil deliveries from Alaska to West Coast ports, including BP refineries in Los Angeles. Calif., and Cherry Point.
The four ships are scheduled to be delivered between now and the end of 2006. Once completed, the four BP ships will be operated by the Alaska Tanker Company of Beaverton. Ore., which operates BP-chartered tankers used in the Alaska North Slope trade.
In September 2000. NASSCO received a $630-million contract from BP for the construction of three state-ofthe- art. double-hull tankers for the carriage of crude oil from Valdez. Alaska, to BP's U.S. West Coast refineries. In September 2001, BP exercised an option for a fourth ship and has options remaining for two additional ships. The ships will incorporate the latest proven technology in ship navigation and cargo and machinery control systems.
The new, 185.000 DWT double-hull ships will have a length of 941 ft. (287 m) and a beam of 164 ft. (50 m).
Capacity w ill be approximately 1.3 million barrels at a design draft of 61.5 ft.
(18.5 m). Construction on the first ship has begun and the ships will be delivered in 2004. 2005 and 2006.
Name Azzura Type Bulk Carrier - Handysize Owner Cello Inc.
Builder IHI Marine United Inc.
IHI Marine United Inc. delivered the Azzura, a 52,000 DWT Handymax size bulk carrier, to Cello Inc. on June 30, 2004 at the Yokohama Shipyard. The Azzura is the first of a series of Future-52 type bulk carriers developed by IHIMU. The Azzura has the optimum dimensions to qualify for worldwide trade, and well-appointed fittings for easy operation and maintenance.
The cargo holds have been strengthened for heavy cargo with holds Nos. 2 and 4 empty, and wide weathertight folding type hatch covers are fitted. Four deck cranes of 30t capacity are provided, and the deck cranes can be fitted with electro-hydraulic grabs as an option. The hold access complies with AWWF requirements.
Since 1967, IHI/IHIMU has delivered over 380 standardized multi-purpose cargo vessels, the well known F-series. The Freedom series, the first of the F-series, was highly evaluated for its excellent operating economy and reliability, and such high performance and evaluation were followed by its successors, the Fortune, Freedom Mark II, Friendship and Future series. The Future-52 was developed as a successor to the superior features of the well established Future series. The Future series has been particularly well evaluated for its operating efficiency from domestic and overseas owners, and the Future-52 retains such good operating efficiency with the maximum deadweight in the Handymax size Future series.
