4) GenSet load responce (see page 2)
5) Verification of GenSet parallel running, if possible (cos
Φ
= 1, unless otherwise stated)
6a) Crankshaft deflection measurement of engines with rigid coupling in both cold and warm condition
6b) Crankshaft deflection measurement of engines with flexible coupling only in cold condition
7) Inspection of lubricating oil filter cartridges of each engine
8) General inspection
The operating values to be measured and recorded during the acceptance test have been specified in accord-
ance with ISO 3046-1:2002 and with the rules of the classification societies.
The operation values are to be confirmed by the customer or his representative, the classification's representa-
tive and the person responsible for the acceptance test by their signature on the test report. After the accept-
ance test components will be checked so far it is possible without dismantling. Dismantling of components is
carried out on the customer's or the classification representative's request.
GenSet load responce
Load application for ship electrical systems
In the age of highly turbocharged diesel engines, building rules of classification societies regarding load appli-
cation (e.g. 0 % => 50 % => 100 %) cannot be complied with, in all cases. However the requirements of the
International Association of Classification Societies (IACS) and ISO 8528-5 are realistic. In the case of ship´s
engines the application of IACS requirements has to be clarified with the respective classification society as
well as with the shipyard and the owner. Therefore the IACS requirements has been established as generel
rule.
