Hi Folks,
Its been quite a few months since there was an update on progress posted here.
Obviously the lock down restrictions have played a part in delaying progress on Waverley's re-boilering.
The previous updates covered the replacement of the generators and boilers - mid June is was time for those iconic funnels to be reinstated.
As is always the case when something significant happens to Waverley there was someone on hand to capture the event or in this case events!
James Watt Dock resident Colin Leck took these shots from his balcony on 17th & 19th June respectively.
As an aside - when Waverley was built she had a double ended Scotch boiler - which meant that there were furnaces at both ends which needed exhausts (or flues) at both ends also. That is why she had two funnels as built. When she was reboilered in 1981 the new Babcock unit was only single ended therefore only exhausted up one funnel (fwd) the same applies when she was reboilered with two units in 2000 and now in 2020. In both cases the boilers exhausted via the fwd funnel.
Her aft funnel contains the exhausts from her diesel driven generator sets. When she was refurbished in 2000 two new generators were fitted - these were replaced during this recent refit and a third was added for redundancy. In addition to this the new generator system allows generators to start and stop when demand dictates (called paralleling) which requires a controller to ensure that the generator frequencies are matched before the additional unit is introduced to the supply otherwise all sort of issues will arise with the electrical equipment on board!
Finally - as stated above the rearmost part of the aft funnel fiddly casing contains the bunkering station which allows her to take on fuel. The rest of the space is used for storage. The fwd fiddly casing is all used for storage - both are accessed via a hatch on top of the casing.

17th June 2020.(1) Shows Aft funnel lying on the quayside - tarpaulin removed ready for lifting. Fwd funnel can be seen just behind her port lifeboat - still under wraps.
(2) Aft funnel slung from crane and lifted from the quayside - - note that the fiddly casing (the brown structure at the base of the funnel) is still attached. This ensures that when the funnel is reattached to the deck it retains the correct rake. This casing also contains the bunkering station which is accessed via two small doors on the rearmost face.
(3) Aft funnel being lowered into position where after careful measurement it was promptly welded to the new steel deck - installed above the boilers.
19th June 2020(5) Waverley's fwd funnel and fiddly casing is lifted from the quayside.
(6) About to be lowered into position on board.
(7) Almost there - again after careful positioning the funnel and casing assembly were welded in place on the deck.
(8 ) Now that looks more like "Oor Lass" now!!
