Crossrail St Barbara Ceremony
We are always up for a challenge and like providing PA systems in unusual locations and circumstances. However our client brief for Crossrail was our first time some 50 metres deep inside the portal of a new railway tunnel!
The event was for a St. Barbara Day ceremony inside the Southern portal of the new Thames Tunnel, which when completed, will link Plumstead and North Woolwich.
We placed a compact d&b audiotechnik E series PA system, with Trantec S5 UHF kit, into a big red cage, which was craned down into the Portal and after passing through rigorous security checks, our event technician climbed down to assemble the kit, ready for the ceremony. Power was simple as we tapped into the 415v three phase supply on site. Surrounded by concrete in all directions and overshadowed by the magnificent 110mtr long Tunnel Boaring Machine 'Sophia', two pairs of d&b E8 loudspeakers were mounted on twin forks, 45deg to the wall and 90 deg to each other, with the system EQ'd to minimise slapback and maintain high sound quality for the priest performing the ceremony.
The ceremony was a great success with the several hundred contractors and senior management in attendance hearing loud & clear audio, thanks to d&b audiotechnik and eventpahire.co.uk We were honoured to be part of this event and wish Crossrail and main contractors HMJV every success with this project. Sophia began her journey under the Thames on 9th January and is progressing the 2.6km stretch at the rate of around 15 metres per day.
