BENTLEY MARINE DUal Fuel Turbine Ship Propulsion

BENTLEY MARINE Next Gen Lightweight Turbines & Compact Gearboxes

 

 
    BENTLEY MARINE integrates innovative Dual-Fuel (LNG/Diesel) Next Gen Marine Turbine Ship Solutions with direct-drive ultra compact reduction gearboxes or Turbo-Electric Propulsion with no parallel in the industry!

    With a Research & Development cost of over 1.5 Billion US Dollars per turbine & gearbox design and extensive Navy use throughout the world, BENTLEY MARINE custom-built turbines and gearboxes are state-of-the-art. These ultimate high-tech machines are the most efficient marine turbines ever, boosting the highest power to weight ratio in the industry.

The world leaders in Green Ship Technologies!

    All BENTLEY MARINE Next Gen Marine Turbines and gearboxes are custom-built for each application and delivered turn-key as a package installation, including all electronic monitoring & control, thermo-acoustic insulated custom inlets and exhausts, filters and fire-suppression systems. They are Dual-Fuel and can operate with regular marine Diesel or with LNG (Liquefied Natural Gas), a clean and environmentally friendly fuel, producing almost ZERO emissions. Performance is slightly better on LNG versions which burn even more efficiently.

The Ultra-Compact ST (Super Turbine) Series:

BENTLEY MARINE ST6

    BENTLEY MARINE compact ST (Super Turbine) range from 500kW up to 4MW (peak output is 5MW). They come equipped with integral ultra-lightweight aluminum magnesium alloy planetary gearboxes for minimum engine room space and Full Authority Digital Electronic Control and Monitoring System.

M (Master) Series:

    Larger ships can benefit from BENTLEY MARINE Master Series models that range from 3360kW up to 110MW.

    The Navy approved M- Series are the only reversible turbines in the world (no need for reversible gearboxes), thus saving tons of weight and space onboard. They are designed for COGAG (Combined Gas & Gas) and COGAS (Combined Gas and Steam) with multiple turbine installations, allowing two higher horsepower turbines to be combined with two smaller ones, by means of special dual-input gearboxes. The innovative system enables any of the turbines on a multiple turbine installation on a Ship to be operated independently on the same shaft for safe propulsion redundancy and best fuel efficiency at all speeds and unsurpassed reliability.

    BENTLEY MARINE custom built ultra-lightweight turbines, gearboxes and integral parts are all manufactured  in the same plants, assuring BENTLEY MARINE's clients immediate availability of parts and faster maintenance and repair jobs, as the same factory technicians can work on the turbines and on the gearboxes. After assembly, all turbines and gearboxes are vigorously tested under BENTLEY MARINE's strict Total Quality Control Program and then professionally installed by our team of certified factory technicians. A two-year full warranty coverage is standard on all BENTLEY MARINE turbines and gearbox packages.

    Like all BENTLEY MARINE machinery and equipment, BENTLEY MARINE turbines and gearboxes are backed by a quick maintenance and repair service that is available around the clock and 365 days a year.

HIGH-POWER PTO DRIVEN GENSETS:

   NEW: Some BENTLEY MARINE Turbines installations can be integrated with a new ultra compact and lightweight High Speed computer-controlled  starter/alternators that act as a marine Genset from main propulsion engines, eliminating the need to have the main propulsion enghine plus the genset running simultaneously. The units are connected to the Turbines via the PTO (Power-Take-Off) gearbox. The innovative energy efficient system enables the ship to automatically shut-down the auxiliary Genset when the main propulsion engines are running, thus saving lots of fuel.
