Operatorworkstations

The Wrtsil Power Management System provides efficient controland monitoring of the power plant and power consumption. Power

management covers the entire chain from the power generating units,

switchgear, power distribution network and variable speed units to the

power users.

The complexity of the power distribution control is built into

the system in such a way that the maximum efficiency performancewill be achieved. Each installation will therefore be configured

individually.

the system. The concept is flexible and can be designed to fit any

configuration of power generation units and propulsion units as well

as other electric power consumers onboard.

In addition to tailor made solutions the low loss concept is

available in five standardized systems: Wrtsil low loss concept 1500,

2700, 3800, 5000 and 10,000 indicating the maximum power of

each of the two main propellers.

For vessels with large power generation and power consumption

a high voltage system is available. The system can be combined with

Wrtsils variable speed drives powering up to 10 MW propulsion units.

The system can be combined with any configuration of powergeneration units and can be tailor made to meet specific requirements

for a flexible power distribution in a variety of different applications.

A combination of a high voltage system for power generation and

a low voltage system for power distribution to the ship consumers

and to special purposes will enhance the flexibility and increase the

operability of the vessel.

Wrtsil Unified ControlsUnique in many aspects, the Wrtsil Unified Controls, UNIC

introduces the only truly flexible and fully scalable control system forlarge reciprocating diesel and gas engines.

High reliability and efficient design

The UNIC system is designed to fulfil the long lifetime expectations

for large marine diesel and gas engines operating in the toughest of

conditions. The system is based on a high degree of commonalities

and standard interfaces, covering different engine sizes and fuel

systems in a modular way. Modular and standardized interface

provides the designer of the off-engine automation systems with easily

reusable design. It allows conversion of e.g. diesel engines to dual fuel

or common rail with a minimum of modifications. Due to the pre-

tested configuration, the engine or generating set is operational with a

minimum of commissioning and installation work.The critical parts of the UNIC system are either redundant or

very fault-tolerant to guarantee high safety and availability in all

circumstances. In particular, parts like the communication and

power supply are fully redundant to allow single failures without

interruptions in engine operation.


10/120

10

Cost-efficient and flexible

With a flexible and scalable design, the number of components

needed is minimized, allowing low-cost logistics and less spare-part

inventory even for different types and sizes of engines. Thanks

to the electronic control, the engine can be adapted to different

operating conditions.

The UNIC C2 and C3 designs follow common industry standards

for fieldbus communication. Through the fieldbus interface, the

UNIC system can be accessed from off-engine automation and HMI

systems as well as from remote service centres. The UNIC system

is optimized for the Wrtsil Condition Based Maintenance system

(CBM).

Unbeaten performance

With unmatched power, the UNIC system provides an unbeaten

performance for engine control. Modern control gives high engine

output, low emissions, high efficiency as well as steady and fast load

acceptance.The electronic fuel injection on UNIC C3 systems allows pre-

post and split injection. Together with the possibility to use multiple

maps, the advanced system drives clean and efficient engines with

electronic fuel injection systems. A key feature in the UNIC system is

a common advanced speed/load control with digital load-sharing and

embedded diagnostics. The speed/load control incorporates timing

control where supported by fuel injection equipment, and advanceddiagnostics to track the control performance and to detect possible

problems. Accurate digital load sharing is used for isochronous

applications. Advanced signal processing allows e.g. knock detection,

cylinder pressure measurements and other diagnostic functions to be

carried out in real time.

The Lipstronic 7000 propulsion control system is computer based,

designed to monitor and control all components in a modern

propulsion system with high accuracy, tailored to the individual

applications.Remote control for controllable pitch propellers

Lipstronic 7000 propulsion control system is designed to optimise

the control of any propulsion machinery. The system exists in two

versions, the basic and the advanced.

The Lipstronic 7000 basic is a cost effective standardised system to

meet most of the demands in the market for propulsion control. Thissystem is applicable for single engine configurations (including twin

screw).

The Lipstronic 7000 advanced introduces a modular designed

system with communication on a two-wire field bus. This gives high

flexibility and multi functionality. This system is applicable to as well

for single as for twin engines configurations.

Both systems are based on Programmable Logic Control (PLC)technology with high accuracy and tailored to the individual

applications. The system controls the propeller pitch position and

engine speed either combined or in split modes. Included is a

propeller- and engine load control system developed on the basis of

research and experience over many years. A large amount of special

functions to optimise ship operations are available.A user-friendly operator panel is delivered. This gives information

of the propulsion plant and is used for calibration of the system. Up

to 31 extra panels can be supplied as options.

Definitions and notes for low-speed engines

Dimensions and weights

All dimensions are in millimetres and are not binding.

The engine weight is net in metric tonnes (t), without oil and

water, and is not binding.

Fuel consumption

All brake specific fuel consumptions (BSFC) are quoted for fuel

of lower calorific value 42.7 MJ/kg (10 200 kcal/kg), and for ISO

standard reference conditions (ISO 15550 and 3046).

The BSFC figures for Wrtsil engines are given with a toleranceof +5%.

Wrtsil RT-flex engines have a lower part-load fuel consumption

than the corresponding Wrtsil RTA engines.

The specific fuel oil consumptions (BSFC) for Mitsubishi UEC

engines are based on ISO standard reference conditions with a

tolerance of 3%. BSFC figures under compliance with IMO-NOx(2000) regulation are different from the figures stated in this catalogue

depending on engine type, rating point, etc. For definite values, please

contact the engine manufacturer.

The values of power in kilowatts and fuel consumption in g/kWh

are the standard figures, and discrepancies occur between these

and the corresponding brake horsepower (bhp) values owing to the

rounding of numbers. For definitive values, please contact our localoffices.

Rating points for Wrtsil low-speed engines

The engine layout fields for

Wrtsil low-speed engines are

defined by the power/speed rating

points R1, R2, R3 and R4 (seediagram left). In certain engines,

the layout field is extended to

the points R1+ and R2+. R1, or

R1+ instead if applicable, is the

nominal maximum continuous

rating (MCR). Any power and

speed within the respective engine

layout field may be selected as the

Contract-MCR (CMCR) point

for an engine.

Rating points for Mitsubishi

UEC low-speed enginesThe engine layout fields for

Mitsubishi UEC engines are

defined by the power / speed

rating points P1, P2, P3, and P4

(see diagram left). Any power and

speed within the respective engine

layout field may be selected as the

Contract-MCR (CMCR) point

for an engine.

Cylinder lubrication

The guide feed rate for cylinder lubricating oil is 1.1 g/kWh for

Wrtsil RTA and RT-flex engines built to the current design

standard. This applies for engine loads in the range of 50 to 100%

and for all fuel sulphur contents from 1.5% upwards.A still lower guide rate of 0.9 g/kWh or less can be used after

analysis of engine performance by a Wrtsil service engineer. For

further information please consult your nearest Wrtsil company.

The low cylinder oil feed rates are made possible by the excellent

and very stable piston-running behaviour routinely obtained by

Wrtsil low-speed engines built to todays standard designs. Not

only are cylinder wear rates low (typically less than 0.04 mm/1000

hours) but also the TBO (time between overhauls) is meeting todays

requirement.

These good results are being achieved by the well-established

Wrtsil load-dependent accumulator cylinder lubricating system. It

has been standard in Wrtsil low-speed engines since the late 1970s,

and has been further developed over the years with the application ofelectronic control.

Load-dependent control ensures that the specific feed rate (g/kWh)

remains virtually constant with reference to the actual operating load.

Wrtsil is introducing the new Pulse Lubricating System to

allow the standard guide feed rate to be reduced to 0.7 g/kWh. It is

an electronically-controlled lubricating system which improves thedistribution of oil on the cylinder liner. Availability upon request.

For further information on this subject, please contact the local

Wrtsil companies.

Available options per thruster type:

Controllable pitch propeller (CS) or fixed pitch propeller (FS).

HR nozzle, 19A nozzle or open propeller.

Weld-in or can-mounted stem box.

Soft on/off clutch or a modulating clutch for FS thrusters.

Remarks:

Bollard pull is based on twin installation, 100% MCR power and 7% thrust deduction with the propellersdesigned for best performance at 0 knots.

Selections are for installations without ice class.

A modulating clutch improves the manouverability for fixed pitch (FS) thrusters at low speeds.

A floating shaft arrangement is applied for installations with the engine in-line with the thruster input shaft.
