Diesel-Electric Propulsion Offers Distinct Advantages

2012-01-27T07:48:00.000-08:00

Power Management , Fuel Economy , Redundancy and Less Noise Are Key Features.

For valid reasons, in recent years diesel-electric propulsion has gained remarkable interest over traditional propulsion within commercial shipping and yachting. Propulsion with the best possible fuel economy, lowest possible emissions, more flexible redundancy arrangements, considerable lower noise and vibration levels, diesel-electric propulsion offers significant economical, environmental and technical advantages. By eliminating the need for a traditional , mechanical gearbox , operating performances are improved.

Every single diesel-generator set is connected to its own generator inverter. For maximum reliability and safety , main propellers and the on-board electric network can be powered jointly by two controller inverters or each single inverter. There is no chance of drifting powerless in the event either a diesel-generator , electric propeller motor , or any one of the inverters malfunction. A diesel-electric system also offers flexibility of addition and expansion of auxiliary equipment like bow thrusters or winches without adding more prime movers. Power cables can be routed much more easily through ship’s bulkheads and decks than traditional mechanical or hydraulic based systems.

Diesel-electric propulsion system is inherently more efficient that a mechanical drive system and therefore the vessel owners can use lesser horse power engines which equate to lower fuel bills, lower maintenance costs and lower emissions.

www.mymarinetracker.com was founded in 2004 by Doug Shupe to provide vessel owners and operators a superior access point for heavy marine equipment brokerage. The typical customer is constrained by their lack of time or limited purchasing staff and therefore turn to this firm for their expertise and many resources. Their website offers a wide selection of ship’s equipment like new, used and rebuilt diesel engines and generators, deck machinery, marine cranes, propellers, anchors and much more.

The Caterpillar 'D' series

2010-06-07T16:04:00.000-07:00

The Caterpillar 'D' series of the 6.25" bore engines is probably the most successful and longest running production engine to date made by Cat. Its' relative simplicity and complete mechanical control made it a popular choice for many equipment manufacturers, ship builders, drill rigs, off-highway trucks and electric power generation around the world. These engines were available in both diesel and natural gas fuel and were all 4-stroke cycle. The six, eight, twelve and sixteen cylinder versions of this engine shared many common internal components with the later three being V-configuration. All of these engines operated at a maximum rpm of 1200 and they developed 70bhp per cylinder upon their initial release.

The series started in 1957 with the in-line 6-cylinder engine model D353 and horsepower starting at 420 at 1200rpm.In 1961 the Caterpillar D379 rated at 560hp, in 1962 the model D398 rated at 850hp and finally in 1967 the 16-cylinder D399 was released and rated at 1120hp. The product line was constantly being improved by Caterpillar engineers and the actual horsepower ratings increased with the improvements. The 6.25" bore engines enjoyed success for almost 33 years when they were discontinued in 1990 and replaced by the 3500 series family. The 'B' version of this series was implemented in approximately 1979-1980 with the revised and angled connecting rod caps which greatly facilitated the disassembly and field service of the engine. A common misconception people have with serial numbers is the letter 'B' within the serial number. This did not represent the later version of the engine as the difference was in the serial number itself. Each engine model had a unique prefix that identified the general application that the engine was intended for when it was manufactured. But over the years there has been conversion by owners from one industry to another, a sign of the engine's versatility. Please see our serial number prefix identification chart here.

The 6.25" bore family of engines still enjoys immense success worldwide even after being out of production for over 18 years. It is especially popular overseas and in third world countries where emission standards are much lower than in the US and where operators may not have the knowledge or financial resources to take care of a more complex 4-stroke diesel engine. Their bullet proof design lets them keep going and going with minimal maintenance. 35-40,000 hours between rebuilds is common with reasonable maintenance. Caterpillar offers premium service around the globe at hundreds of dealers and distributors as well as many quality aftermarket sources.
