Introduction Introduction The Project Guide provides main engine data and system proposals for the early design phase of engine installations. For contracted projects specific instructions for planning the installation are always delivered. The 2/1997 issue replaces all previous ones of the Vasa 32 Project Guide. Major revisions of issue 2/1997: The heat balance of the low NO X engines is revised according to the latest laboratory measurements. Major revisions of issue 1/1997: Information concerning the low NO X emission model, Vasa 32 LN, is now presented in parallel with information on the basic Vasa 32. Where no distinction is made, the data applies to both engine types. Technical data is revised in accordance with the current engine specifications. Exhaust gas pipe dimensions are for some cylinder numbers increased. Lists of suitable fuel and lubricating oil separators are included. Instructions on engine room ventilation are added. Emission control methods are described. The code numbers of electrical components are new. Engine seating instructions are extended. Piping interface points are better defined with reference to standard and pressure class. The information provided in this Project Guide is subject to revision without notice. Comments and suggestions to the contents of the Project Guide are welcome.

1. General data and outputs 1. General data and outputs 1.1. Main technical data The Wärtsilä Vasa 32 is a 4-stroke, non-reversible, turbocharged and intercooled diesel engine with direct fuel injection. Cylinder bore 320 mm Stroke 350 mm Piston displacement 28.2 l/cylinder Number of valves 2 inlet valves and 2 exhaust valves Cylinder configuration 4, 6, 8 and 9 in-line 12, 16 and 18 in V-form V-angle 50 Compression ratio 12.0:1 13.8:1 (Low NO X ) Direction of rotation, seen from flywheel end Speed D-rating clockwise, counter-clockwise on request Cylinder output E-rating 720 RPM 370 kw 503 hp 405 kw 550 hp 750 RPM 375 kw 510 hp 410 kw 557 hp Fuel consumption Lube oil consumption 1.2. Fuel specification see Technical Data see Technical Data Viscosity at 50 C, max. 730 cst Viscosity at 100 F, max. 7200 sri Density at 15 C, max. 0.991 kg/dm³ / 1.010 kg/dm³ Conradson Carbon Residue, max. 22% by weight Sulphur content, max. 5.0% by weight Vanadium content, max. 600 ppm Sodium content, max. 50 ppm Ash, max. 0.20% by weight Water content, max. 1.0% by volume Water content before engine, max. 0.3% by volume Pour point, max. 30 C Asphaltenes, max. 14% by weight Aluminium + silicon, max. 80 ppm Flash point, closed Pensky Martens, min. 60 C The fuel specification corresponds to fuel according to ISO 8217 : 1996 (E) categories up to ISO-F-RMK 55. Maximum limits for sodium, water content before engine and asphaltenes have been added. Provided the fuel treatment system can remove water and solids. Sodium contributes to hot corrosion on exhaust valves when combined with high vanadium content. Sodium also contributes strongly to fouling of the exhaust gas turbine blading at high load. The aggressiveness of the fuel depends not only on its proportions of sodium and vanadium but also on the total amount of ash. Hot corrosion and deposit formation are, however, also influenced by other ash constituents. It is therefore difficult to set strict limits based only on the sodium and vanadium content of the fuel. Also a fuel with lower sodium and vanadium contents than specified above can cause hot corrosion on engine components. 1.3. Lubricating oil quality Engine The system oil should be of viscosity class SAE 40 (ISO VG 150). Oils of viscosity class SAE 30 (ISO VG 100) may also be used. The content of additives should meet the requirement of MIL-L-2104C or API Service CD. The alkalinity, TBN, of the system oil should be 25-40 mg/koh/g]; higher at higher sulphur content of the fuel. During the warranty period, lubricating oil of an approved type has to be used. Turbocharger For ABB turbochargers with roller bearings a turbine oil must be used. The oil may be a mineral oil or a synthetic oil having a viscosity of 30-55 cst/50 C. Other makes of turbochargers and turbochargers with sleeve bearings are lubricated from the main lubricating oil circuit of the engine. Marine Project Guide WV32-2/1997 3

The maximum fuel rack position is mechanically limited to 110% continuous output. The alternator outputs are calculated for an efficiency of 0.965 and a power factor of 0.8. The above output is also available from the free end of the engine, if necessary. The cylinder output P¹ can be calculated as follows: P¹ (kw) = pe (bar) x n (RPM) x 0.0235 P¹ (hp) = pe (bar) x n (RPM) x 0.0319 where P¹ = output per cylinder pe = mean effective pressure n = engine speed The maximum fuel rack position is mechanically limited to 100%. 4 Marine Project Guide WV32-2/1997

1. General data and outputs 1.5. Reference conditions The maximum continuous output is available at a max. charge air coolant temperature of 38 C, a max. air temperature of 45 C and a max. exhaust gas back pressure of 300 mmwc. If the actual figures exceed these, the engine should be derated. The fuel consumption indicated in Technical Data is valid in reference conditions according to ISO 3046/1-1986, i.e.: 1.6. Principal dimensions and weights In-line engines (3V58E0425c) total barometric pressure 1.0 bar air temperature 25 C relative humidity 30% charge air coolant temperature 25 C For other than ISO 3046/I conditions the same standard gives correction factors. The influence of an engine driven lube oil pump on the specific fuel consumption is about 2 g/kwh and of each engine driven cooling water pump about 1 g/kwh, at full load and nominal speed.

2. Operational data 2. Operational data 2.1. Dimensioning of propellers Controllable pitch (CP) propellers Controllable pitch propellers are designed so that 100% of the maximum continuous engine output at nominal speed can be utilized. The propeller is usually optimized for service speed and draft at about 85% engine MCR and a sea margin of 10-15%. Shaft generators must be considered when dimensioning propellers, if the generator will be used at sea. Overload protection or load control is recommended in all installations. In installations where several engines are connected to the same propeller, overload protection or load control is necessary. The graph 4V93L0383 shows the operating range for a CP-propeller installation. The recommended combinator curve and the 100% load curve are valid for a singleengine installation. For twin-engine installations a lighter combinator program is used if only one engine is in operation. The idling (clutch-in) speed should be as high as possible and will be decided separately in each case.

2. Operational data Fixed pitch (FP) propellers The dimensioning of fixed pitch propellers should be made very thoroughly for every vessel as there are only limited possibilities to control the absorbed power. Factors which influence the design are: The resistance of the ship increases with time due to fouling of the hull. The wake factor of the ship increases with time. The propeller blade frictional resistance in water increases with time. Wind and sea state will increase the resistance of the ship Increased draught and trim due to different load conditions will increase the resistance of the ship. Bollard pull requires higher torque than free running. Propellers rotating in ice require higher torque. The FP-propeller shall be designed to absorb 85% or the maximum continuous output of the engine at nominal speed when the ship is on trial, at specified speed and load. In ships intended for towing, the propeller can be designed for 95% of the maximum continuous output of the engine at nominal speed in bollard pull or at towing speed. The absorbed power at free running and nominal speed in usually then relatively low, 55-75% of the output at bollard pull. In ships intended for operation in heavy ice, the additional torque of the ice shall be considered. The graph 4V93L0423 shows the permissible operating range for an FP-propeller installation as well as the recommended design point at 85% MCR and nominal speed. The min. speed will be decided separately for each installation. It is recommended that the speed control system is designed to give a speed boost signal to the speed governor in order to prevent the engine speed from decreasing when clutching-in. The clutch should be dimensioned for a slipping time of 5-8 seconds. A propeller shaft brake should be used to enable fast manoeuvering (crash-stop).

2. Operational data 2.2. Loading capacity for generating sets Provided that the engine is preheated so that the min. cooling water temperature is 70 C, the engine can be loaded immediately after start with no restrictions except the maximum transient frequency deviation specified by the classification societies. For supercharged engines, 100% load cannot be instantly applied due to the air deficit until the turbocharger has accelerated. At instant loading the speed and the frequency drop. The engine can be loaded most quickly by a successive, gradual increase in load from 0 to 100% over a certain time (t 1 ) as shown in the following diagrams. Loading in two steps, with a load application in the first step by highest possible load (= max. permissible instant frequency drop) will take the longest time to achieve table frequency. Therefore, it is recommended that the switchboards and the power management are designed to increase the load in three or four steps, from 0 to 100%, as also suggested by the International Association of Classification Societies (IACS). This shall be done with the agreement of the relevant classification society. The stated values of loading performance as presented in 1V93F0093 are guidance values; the values will also be affected by the mass-moment of inertia of the set, the governor adjustment and nominal output. Unless otherwise agreed the present requirements of the classification societies for load application on generating sets at an instant speed drop of 10% are: American Bureau of Shipping 0-50 - 100% Bureau Veritas 50% on base load of 0-50% Det Norske Veritas 0-50 - 100% Germanischer Lloyd 0-50 - 100% Registro Italiano Navale 0-50 - 100% Maritime Register 0-50 - 100% Lloyd s Register of Shipping 0-800/pe - [800/pe + ½ (100-800/pe)] - 100% Loading performance (1V93F0093) Marine Project Guide WV32-2/1997 11

2. Operational data Successive load application t 1 = t 2 = t 4 = shortest possible time of successive, gradually increased load for a speed (and frequency) drop of max. 10% = 5 seconds time elapsing before the speed has stabilized at the initial value (speed droop = 0%) = 7 seconds time elapsing before the speed has stabilized at the new value determined by the speed droop (speed droop = 4%) = 6.5 seconds Instant unloading t 3 = time elapsing before the speed has stabilized at the initial value (speed droop = 0%) = 2 seconds t 5 = time elapsing before the speed has stabilized at the new value determined by the speed droop (speed droop = 4%) = 1.8 seconds n 1 = increase in speed at instant unloading (speed droop = 0%) = 8% n 2 = increase in speed at instant unloading (speed droop = 4%) <10% 2.3. Restrictions for low load operation and idling The engine can be started, stopped and run on heavy fuel under all operating conditions. Continuous operation on heavy fuel is preferred instead of changing over to diesel fuel at low load operation and manoeuvering. The following recommendations apply to idling and low load operation: Absolute idling (declutched main engine, unloaded generator) Max. 10 min., (recommended3-5min.), if the engine is to be stopped after the idling. Max. 6 hours if the engine is to be loaded after the idling. Operation at 5-20% load Max. 100 hours continuous operation. At intervals of 100 operating hours the engine must be loaded to min. 70% of the rated load. Operation at higher than 20% load No restrictions. Instant load application P x = highest possible load which can be instantly applied causing a speed drop of max. 10% = 50% t 6 = shortest possible time elapsing between the first and second load application = 5 seconds t 7 = time elapsing before the speed has stabilized at the initial value (speed droop = 0%) = 9 seconds t 8 = time elapsing before the speed has stabilized at the new value determined by the speed droop (speed droop = 4%) = 8.5 seconds 12 Marine Project Guide WV32-2/1997
