AMERICAN LIGURIAN

Circle 11 on Reader Service Card

American Ligurian Company of

Stamford, Conn., represents Bau- douin of Marseille, France, and

Castoldi Jet of Milan and O.M.T. of Turin, Italy.

Baudouin designs and manufac- tures 4-cycle, water-cooled, direct injection marine diesel engines with outputs ranging from 75 to 1,200 bhp. These engines are specifically designed for marine applications, with long life, relia- ble performance, and economical maintenance. All Baudoin engines have been approved by the leading classification societies.

Baudouin also designs and builds: complete oil-lubricated line shafts of 40 to 200 millimeter di- ameter; water-lubricated line shafts of 40-70 mm; and stern type gland systems. These line shafts, to- gether with the stern tube, cou- plings, bearings, seals, and the en- tire technical method of installation provides a fully proven assembly.

Castoldi hydrojet marine pro- pulsion units include five lines, 03-07, applicable to engines with outputs from 5 to 1,400 bhp.

Complete marine units include:

The Castoldi/B&S 700/03, air- cooled, 13.2-kw direct-coupled unit; the Castoldi/Fiat 970/04, water- cooled 22.09-kw direct-coupled unit; and five Castoldi/Fiat water-cooled units ranging from 38.3 to 99.3 kw.

O.M.T. offers for the OEM and after-sales markets a line of noz- zles, nozzle holders, injection pumps, plungers, and delivery valves that are interchangeable with the ones used by the leading diesel engine builders.

BERGEN DIESEL

Circle 12 on Reader Service Card

A.S. Bergens Mekaniske Verk- steder (Bergen Diesel) of Norway has used heavy fuel in its engines for more than 20 years and has very solid experience in this field.

Some 500 engines, both propulsion and generator sets, are in opera- tion on heavy fuel, with the long- est running times in excess of 100,000 hours. The company's U.S. subsidiary, Bergen Diesel, Inc., is located in Kenner (New Orleans), La.

This extensive experience, to- gether with in-depth development work to meet the challenges of the poorer quality fuels, has meant that Bergen Diesel today delivers its K engine for unrestricted oper- ation with fuel viscosities up to 700 cSt at 50 C. The K engine is delivered in in-line form with three, five, six, eight, and nine cylinders, and as a V engine with 12, 16, and 18 cylinders. With a speed range of 720 to 900 rpm and mean effec- tive pressures of 16—18 bars, they cover a power output range of 600 to 4,500 bhp. Their main applica- tions are in generating sets and propulsion engines for ships.

Despite the declining quality, recent experience with heavy oil has shown very good operational results, for example, 10,000 hours between cylinder head overhauls and 20,000 hours for the running gear. Upper cylinder liner wear is less than 0.01 mm per 1,000 hours, and the life of the cylinder liner is about 60,000 hours.

Recently there have been great improvements in this area, due mainly to higher injection pres- sures and reduced nozzle hole size.

Both contribute to better atomiza- tion and thereby improved com- bustion, particularly of the heav- ier hydrocarbons that today's heavy oils contain. The injection period is also reduced, which gives a con- siderable reduction in fuel con- sumption. Optimum fuel consump- tions are now 142 grams per bhp hour without engine-driven lube oil and cooling water pumps, and 145 grams per bhp hour with engine-driven pumps.

Special attention has been given to the hydraulic forces arising in the fuel system, which insures a longer life for the nozzles and pump components. The system is designed for and endurance tested at an injection pressure of 1,500 bars, but in normal operation runs at a maximum of about 1,200 bars, (continued on page 20)

Todd gives berth to a president up jfej*.

Recently, the 33,000 ton President Washington was drydocked at Todd's Seattle shipyard. It was the largest commercial ship ever drydocked in

Puget Sound, but there was still room to spare on the mammoth 873' x 140' dry dock.

This newly installed, 40,000 ton dry dock is just a portion of many facility improvements Todd has implemented in recent months. The company has also upgraded its other shipyards at Los Angeles,

San Francisco, Galveston and New Orleans.

Our modern, capable and efficient shipyards provide fast turnaround and around-the-clock service. Whether it be a minor voyage repair, propeller and tailshaft repairs, a major overhaul or an extensive conversion job, we have the expertise and resources to get the job done with professionalism.

If you're looking for expert, dependable ship- yard service on the U.S. Gulf or West Coasts, why not call on TODD — the professionals!
