For contracted projects specific instructions for planning the installationare 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 NOX engines is revised according to the latest laboratory measurements.Major revisions of issue 1/1997:Information concerning the low NOX emission model, Vasa 32 LN, is now presented in parallelwith information on the basic Vasa 32. Where no distinction is made, the data applies to bothengine 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.

1.2. Fuel specification

The fuel specification corresponds to fuel according toISO 8217 : 1996 (E) categories up to ISO-F-RMK 55.Maximum limits for sodium, water content before engineand asphaltenes have been added. Provided the fuel treatment system can remove

water and solids.

Sodium contributes to hot corrosion on exhaustvalves when combined with high vanadium con-tent. Sodium also contributes strongly to fouling ofthe exhaust gas turbine blading at high load. Theaggressiveness of the fuel depends not only on itsproportions of sodium and vanadium but also onthe total amount of ash. Hot corrosion and depositformation are, however, also influenced by otherash constituents. It is therefore difficult to set strictlimits based only on the sodium and vanadiumcontent of the fuel. Also a fuel with lower sodiumand vanadium contents than specified above cancause hot corrosion on engine components.

1.3. Lubricating oil quality

Engine

The system oil should be of viscosity class SAE 40 (ISOVG 150). Oils of viscosity class SAE 30 (ISO VG 100)may also be used. The content of additives should meetthe requirement of MIL-L-2104C or API Service CD.The alkalinity, TBN, of the system oil should be 25 - 40mg/KOH/g]; higher at higher sulphur content of the fuel.

During the warranty period, lubricating oil of an approvedtype has to be used.

Turbocharger

For ABB turbochargers with roller bearings a turbine oilmust be used. The oil may be a mineral oil or a syntheticoil having a viscosity of 30 - 55 cSt/50C.Other makes of turbochargers and turbochargers withsleeve bearings are lubricated from the main lubricatingoil circuit of the engine.

For auxiliary engines the permissible overload is 10% forone hour every twelve hours. The maximum fuel rack po-sition is mechanically limited to 110% continuous output.The alternator outputs are calculated for an efficiency of0.965 and a power factor of 0.8.The above output is also available from the free end ofthe engine, if necessary.The cylinder output P can be calculated as follows:P (kW) = pe (bar) x n (RPM) x 0.0235P (hp) = pe (bar) x n (RPM) x 0.0319

whereP = output per cylinderpe = mean effective pressuren = engine speed



1.5. Reference conditions

The maximum continuous output is available at a max.charge air coolant temperature of 38C, a max. air tem-perature of 45C and a max. exhaust gas back pressureof 300 mmWC. If the actual figures exceed these, the en-gine should be derated.The fuel consumption indicated in Technical Data is validin reference conditions according to ISO 3046/1-1986,i.e.:

total barometric pressure 1.0 bar air temperature 25C relative humidity 30% charge air coolant temperature 25CFor other than ISO 3046/I conditions the same standardgives correction factors.The influence of an engine driven lube oil pump on thespecific fuel consumption is about 2 g/kWh and of eachengine driven cooling water pump about 1 g/kWh, at fullload and nominal speed.

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 nominalspeed can be utilized. The propeller is usually optimizedfor service speed and draft at about 85% engine MCRand a sea margin of 10 - 15%. Shaft generators must beconsidered when dimensioning propellers, if the gener-ator will be used at sea.

Overload protection or load control is recommended inall installations. In installations where several enginesare connected to the same propeller, overload protectionor load control is necessary.

Operating range, Wrtsil Vasa 32D + LN D, CP-

propeller (4V93L0383c)

The graph 4V93L0383 shows the operating range for aCP-propeller installation. The recommended combinatorcurve and the 100% load curve are valid for a single-engine installation. For twin-engine installations a lightercombinator program is used if only one engine is in op-eration.

The idling (clutch-in) speed should be as high as possi-ble and will be decided separately in each case.

Operating range, Wrtsil Vasa 32E + LN E, CP-

propeller (4V93L0422b)


2. Operational data

Fixed pitch (FP) propellers

The dimensioning of fixed pitch propellers should bemade very thoroughly for every vessel as there are onlylimited possibilities to control the absorbed power. Fac-tors 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 in-

creases with time. Wind and sea state will increase the resistance of the

ship Increased draught and trim due to different load condi-

tions 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 themaximum continuous output of the engine at nominalspeed when the ship is on trial, at specified speed andload.

Operating range, Wrtsil Vasa 32D + LN D, FP-

propeller (4V93L0384c)

In ships intended for towing, the propeller can be de-signed for 95% of the maximum continuous output of theengine at nominal speed in bollard pull or at towingspeed. The absorbed power at free running and nominalspeed in usually then relatively low, 55 - 75% of the out-put at bollard pull.In ships intended for operation in heavy ice, the addi-tional torque of the ice shall be considered.The graph 4V93L0423 shows the permissible operatingrange for an FP-propeller installation as well as the rec-ommended design point at 85% MCR and nominalspeed. The min. speed will be decided separately foreach installation. It is recommended that the speed con-trol system is designed to give a speed boost signal tothe speed governor in order to prevent the engine speedfrom decreasing when clutching-in.The clutch should be dimensioned for a slipping time of 5- 8 seconds. A propeller shaft brake should be used toenable fast manoeuvering (crash-stop).

2.2. Loading capacity for generating sets

Provided that the engine is preheated so that the min.cooling water temperature is 70C, the engine can beloaded immediately after start with no restrictions exceptthe maximum transient frequency deviation specified bythe classification societies. For supercharged engines,100% load cannot be instantly applied due to the air defi-cit until the turbocharger has accelerated. At instant load-ing 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 certaintime (t1) as shown in the following diagrams. Loading intwo steps, with a load application in the first step by high-est possible load (= max. permissible instant frequencydrop) will take the longest time to achieve table fre-quency. Therefore, it is recommended that the switch-boards and the power management are designed toincrease the load in three or four steps, from 0 to 100%,as also suggested by the International Association ofClassification Societies (IACS). This shall be done withthe agreement of the relevant classification society.

The stated values of loading performance as presentedin 1V93F0093 are guidance values; the values will alsobe affected by the mass-moment of inertia of the set, thegovernor adjustment and nominal output.Unless otherwise agreed the present requirements ofthe classification societies for load application on gener-ating 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% Lloyds Register of
