The Ogden Dynachem, the first of two chemical product carriers currently under con- struction at Avondale Shipyards, Inc. for Ogden Marine Inc., was christened recent- ly. The 629-foot-long, fuel-efficient vessel will be time-chartered by Diamond Sham- rock Corporation's Ocean Systems Department.

M/V Ogden Dynachem

Christened At Avondale

Avondale Shipyards, Inc., New

Orleans, La., a subsidiary of Og- den Corporation, held christening ceremonies for the M/V Ogden

Dynachem, the first of two 42,000- dwt chemical product carriers currently being built for Ogden

Marine, Inc.

Mrs. Doris Bricker, wife of

William H. Bricker, chairman and chief executive officer of Diamond

Shamrock Corporation, served as sponsor of the Ogden Dynachem.

Principals of the M/V Ogden

Dynachem christening ceremony were Albert L. Bossier Jr., presi- dent of Avondale Shipyards, Inc., presiding over the ceremony; and

William H. Bricker, chairman and chief executive officer of Diamond

Shamrock Corporation, delivering the principal address.

Miss April Dawn Chauff, daughter of Mr. and Mrs. Lowell

G. Chauff, served as flower girl, a role traditionally filled by the daughter of an Avondale Ship- yard's employee. Miss Chauff's father is an electrician specialist at the main plant.

The new ship will cost approxi- mately $70 million and is the first conventional chemical ship to be built in the United States in over a decade.

Designed for the transporta- tion of caustic soda, Type II and

Type III chemical products, and

Grade A petroleum products, the

M/V Ogden Dynachem will oper- ate in the United States domestic chemical trade, refined oil prod- ucts trade and Alaskan crude oil trade, serving the Gulf and East

Coast ports.

The M/V Ogden Dynachem will be time-chartered by Diamond

Mrs. Doris Bricker, wife of William H.

Bricker, chairman and chief executive of- ficer of Diamond Shamrock Corporation, presided over bottle-breaking ceremonies.

Shamrock Corporation for 15 years with two five-year exten- sion options. Under the contract agreement, Diamond Shamrock

Corporation's Ocean Systems De- partment will handle all commer- cial arrangements while Ogden

Marine, Inc. will own and operate the vessel.

Through Diamond Shamrock's

Houston-based Ocean Systems

Department, the Ogden Dyna- chem and a sister vessel will sub- charter tank space to transport products for other companies as well. The Ogden Dynachem more than doubles Diamond Shamrock

Ocean System's combined vessel capacity to over 97,000 dead- weight tons and more than doubles cargo capacity to over 1.3 million tons yearly.

Powered by a fuel-efficient, twin-bank Hitachi B&W 2 X 8K45GT slow-speed diesel and having a service speed of 15.5 knots at 12,800 bhp, the Ogden

Dynachem is 629 feet long, has a beam of 106 feet, depth of 60 feet and scantling draft of 43.5 feet.

The engines turn a single 23.5- foot-diameter four-blade pro- peller.

Construction of the Ogden Dy- nachem began in June 1980 at

Avondale, which is a subsidiary of the Ogden Corporation.

In addition to a broad range of chemicals, the 629-foot vessel's 18 cargo tanks in 12 segregations allow the Ogden Dynachem to also transport crude oil, refined petroleum products and vegetable and animal oils. The Ogden Dy- nachem's multiproduct cargo sys- tem and ship configuration were designed for transportation of 50 percent solution caustic soda,

Grade A petroleum products and

Type II and III chemicals having specific gravities up to 1.62.

The tanker will be among the safest at sea, fitted with many advanced design features and built to meet or exceed the latest

USCG and IMCO requirements for bulk carriers of hazardous mater- ials.

The Ogden Dynachem incorpor- ates state-of-the-art technology including electronic gaging and control systems, inorganic zinc- coated and hi-build epoxy-coated tanks to assure cargo integrity, an independently generated com- bustion-preventive inert gas sys- tem in the cargo tanks and fully segregated cargo handling and control systems.

A full double bottom and the size and number of cargo segre- gations provide for full compli- ance with pollution prevention regulations for outflow, tank length and tank volumes as well as provide defensively positioned, segregated discharge ballast. The cargo tank area is further pro- tected by an alcohol-based polar solvent foam system, intrinsically safe electric equipment, automatic high-level shutdown filling valves and stringent material restric- tions.

The vessel's fuel-efficient, closed-loop control inert gas gen- erator is a low velocity displace- ment system with a common dis- tribution header and check valve isolation into each cargo segrega- tion. Independent high-level alarms afford additional overfill protection.

A Frank Mohn submerged, hy- draulic pumping system with in- dividual cargo pump per tank al- lows segregated handling of chem- ical and petroleum products of a wide range of specific gravities, vapor pressures and viscosities.

An electronic cargo control system integrates into a single remote cargo control panel the central hydraulic system opera- tion, cargo pump control, hydraul- ic valve actuation, cargo tank lev- el gaging, tank temperature monitors, inert gas control sys- tem, ballast system operation and gaging and emergency shutdown system.

In his review of a paper detail- ing the Ogden Dynachem's design presented to The Society of Naval

Architects and Marine Engineers bv the ship's naval architects,

USCG Comdr. D.F. Bobeck said: "To say that the vessel's design is unique and worthy of special con- sideration is surely an understate- ment. To design a vessel to meet only the owner's requirements would test the mettle of most naval architects and marine en- gineers. To design a vessel to also incorporate many novel features and meet the new regulations promulgated by the Coast Guard
