Of Hopper Dredge
Southern Shipbuilding Corpora- tion recently delivered the hopper dredge Sandy Hook to McCormack
Aggregates, South Amboy, N.J., af- ter the vessel underwent conversion at the Slidell, La., yard.
The 290-foot Sandy Hook was converted from the hopper barge
Harold Smith, which formerly transported petroleum coke be- tween Norfolk, Va., and Philadel- phia, Pa.
The extensive conversion of the 60-foot-wide, 21-foot-deep barge in- cluded adding dredging and gener- ating equipment. Installed were two 12-cylinder EMD 12-645 diesel en- gines, each developing 1,500 hp and generating 1,150 kw of electrical power for operating the dredging equipment and on-board lighting.

McCormack Aggregates, a joint venture of 98-year-old Great Lakes
Dredge & Dock Co., Oakbrook, 111., and McCormack Sand Co., High- stown, N.J., operates the Sandy
Hook in lower New York Bay be- tween the New York and New Jer- sey shores, mining sand and gravel at a rate of about 800,000 cubic yards per year. The sand and gravel is transported 25 miles to McCor- mack Aggregates' plant at South

In addition to the NavSea orders,
Bird-Johnson's Pascagoula opera- tion is working on new construction propeller orders for several U.S. and foreign customers and are pouring controllable pitch propeller (CPP) blades for both intracompany and outside customer CPP system pro- duction. With orders booked into the 1990s, they have the largest work backlog in their history and expect to increase their personnel base by 20 before the end of 1989 to meet the demand. This will reflect a near tripling of staff since Bird-
Johnson's 1986 acquisition of the facility.
Bird-Johnson Company has been a world leader in the manufacture of
CPP systems for over 30 years.
Since their 1986 purchase of the former Pascagoula and Seattle,
Wash., Coolidge fixed pitch propel- ler manufacturing plants they have become the only fully integrated marine propeller manufacturer in the U.S.
Bird-Johnson Company is a whol- ly owned subsidiary of Axel Johnson
Inc., a privately held, multi-indus- try corporation headquartered in

Bird-Johnson To Expand
Bird-Johnson Company's Pasca- goula, Miss., plant manager Jim El- liott has announced plans to ex- pand their marine propeller manu- facturing plant to meet the de- mands of new orders. The current 43,000-square-foot facility, which houses a modern foundry as well as a complete propeller machining and repair shop, will be enlarged by 15,000 square feet. About 9,000 square feet will accommodate a re- alignment of the molding stations in the foundry area and double po- tential monobloc propeller and con- trollable pitch propeller blade pro- duction. The other 6,000 square feet will be added to the machining area.
Construction will begin immediate- ly and is slated for completion in
The expansion was necessitated by record sales in 1987 and 1988.
During 1988 alone, Pascagoula has received 30 of 37 spare marine pro- peller orders placed by The Naval
Sea Systems Command (NavSea).
Recent NavSea orders have in- cluded spare propellers for the LKA
Charleston class amphibious cargo ships, LCC Blue Ridge class amphi- bious command ships, FF 1052

OnlyWestfalia's On-Demand Purifying
System Removes > All the Dirt and Water from your 1010 fuel.
Whether your fuel oil is heavier or lighter than water, only Westfalia's two-stage Unitrol/Secutrol system assures maximum purity even under widely varying feed conditions.
On-demand vs timer-controlled de-sludging.
Other oil purification systems are timer-controlled, which means they de-sludge only at pre-set intervals. If heavy seas stir-up the "muck" in your fuel tanks, the intervals may be too far apart. Result: dirt gets into your day tank and fuel lines, causing disastrous engine wear...In the Westfalia system, a unique sensor continuously monitors de-sludging intervals, discharging dirt and water only when the sediment-holding compartment^is full. So there's no chance for dirt to get into your fuel because of too few de-sludgings — or fuel wastage from too-frequent de-sludgings.
And either stage can be operated independently, thus adding even more flexibility.
No water in fuel lines.
With Westfalia's unique design, there's no way water can enter the clean fuel line. With other systems, this is a distinct possibility.
No matter how wide the variations in density or feed characteristics, you get the most efficient, reliable purification. Automatically, with no need for gravity disc changes.
For maximum reliability we've substituted simplicity for complex electronics and intricate circuitry. Thus Westfalia purifiers are more dependable and much less likely to break down than other separators. Contact
Centrico for the Westfalia system you need. ^mmmrn
