Measuring up at Arnish
10 Jun 11 - Ian Rose, Quality Manager
Last week I visited a rather windswept Arnish Point on the Isle
of Lewis to witness the dimensional check on the Oyster 2 North and
South piles.
Manufacture on both piles was in full swing, so it wasn't easy
for John McLeod (Dimensional Controller) to get access. John
uses a Leica TCR1105 to conduct the survey. This equipment
references five fixed points within the facility then uses these
points as a datum. John then takes a measurement, bouncing
the laser off a reflector and takes readings relative to the fixed
points and reaches a precise measurement. All measurements
are then compared against the drawing and documented.
Measurements such as ovality, straightness and diameter are
critical and proved to be well within the tolerance specified on
our drawings. Well done to the guys from BiFab in Arnish for doing
a great job.
Earlier this week our HSE Manager Eddie Scott was also in Arnish
to witness the load out of each of the piles. The piles are now en
route to Orkney where installation of Oyster 2 will commence
shortly.
