It will be necessary to come back to these claims in
more detail ata iater stage, but some further matters can
conveniently be noted at this point. Most, but not all, of the
first invoice, for an amount of $320.00, related to the mounting
and testing of the compressor; only a relatively small sum
should be attributed to the further removal of the compressor
from the rig for derating. With respect to the second invoice,
for $8662.87, evidence was given that $6697.12 related to parts
and $1965.75 was for lapour at $24.00 per hour. Approximately 50
hours were spent derating the compressor, another 15 hours
approximately were otherwise spent "in the compressor area", and
about 17 hours were spent removing the clutch and installing the
substitute clutches, installing new belts, and testing and
running the compressor. IT am satisified that the upgraded
clutches installed were appropriate, given the other steps taken
by Mr Bourne including the derating of the compressor which will
be further discussed below, and that the new belts were necessary
because the previous belts had deteriorated by reason of the
problems which had been experienced with the compressor drive
train and the compressor. However, f£ am not satisfied that there
was any need to instal the new compressor base and belt
tensioning system to facilitate the adjustment of the belts to
permit proper tensioning to be obtained and maintained; I find
that this modification was no more than a matter of preference on
the part of the applicant and Mr Bourne. On the other hand, I
find that neither the modifications to the compressor base and
belt tensioning system nor any cther modification effected by the
applicant or on its behalf in any way caused or contributed to
