__Main Propulsion Diesel Engines__(MPDEs)

At this stage, the

**ICeBeRG**would most likely go for the MTU 8000 16V M71L :__Rated power ICFN__: 7,280 kW / 9,762 bhp @ 1,150 rpm

__Fuel consumption__: 196 g/kWh @ rated power / 188 g/kWh @ optimum

In terms of engine room arrangement, minimum distances would be as follows :

For each pair of MPDEs, this would mean a total width of about 6,500 mm (2,040*2 + 800*3), i.e. about 21.3 ft, and a total height (excluding foundations) of about 4,175 mm (3,375 + 800), i.e. about 13.7 ft.

**2)**

__Main Reduction Gears__(MRGs)

At this stage, the

**ICeBeRG**would be tempted to go for the DCNS Raft-Mounted Propulsion System (RMPS) to achieve good acoustic discretion and shock resistance.Based on the F-70 AAW frigates, this would probably dictate a length somewhere between 12 and 13 meters (about 40 to 43 feet) for each engine room.

**3)**

__Dieseil Gensets__(SSDGs)

At this stage, the

**ICeBeRG**would most likely go for the MTU 4000 16V M53B (shown below is the 20V with an acoustic enclosure) :Estimated specifications below :

* Length = approx. 19.0 ft / 5,800 mm

* Width = approx. 7.0 ft / 2,100 mm

* Height = approx 10.0 ft / 3,000 mm

* Dry Mass = approx. 42,000 lbs / 19,000 kg

* Rated power = 2,240 Eng. kW @ 1,800 rpm

* SFC = 220 g/kWh

* Width = approx. 7.0 ft / 2,100 mm

* Height = approx 10.0 ft / 3,000 mm

* Dry Mass = approx. 42,000 lbs / 19,000 kg

* Rated power = 2,240 Eng. kW @ 1,800 rpm

* SFC = 220 g/kWh

To keep the propulsion system as compact as possible, the

**ICeBeRG**envisions two (2) such SSDGs in each engine room, together with the MDPEs.As a result, each engine room would likely end up being about 13 meters long, 13 meters wide and 5 meters high once the RMPS is accounted for (i.e. about 43ft x 43ft x 17ft).

**4)**

__Propulsion system arrangement__

To ensurance adequate survivability, the engine room would be separated by a 10-meter long intermediate compartment (for auxiliary equipment & workshop), in a sommewhat similar arrangement to the

*Suffren*&*Duquesne*frigates :The propulsion system would therefore end up being about 36 meters long in total (about 120 feet). Each compartment would be separated by blast-hardened double bulkheads to maximize survivability.
