Offshore
The close proximity of powerful machinery with a working and
resting workforce highlights the challenge facing the noise control
specialist designing offshore installations. Safety concerns
are of course paramount and prediction through generating noise
contours on each deck allows, for example, for the design critical
Public Address systems in unavoidably noisy working areas. In
other working areas such as control rooms, noise has to be reduced
to allow normal communication and telephone usage.
But it is away from the machinery areas where the real difficulties
arise, in the associated living quarters, where levels of noise
and vibration consistent with good sleep are needed. Environmental
Standards for noise will depend upon local country regulations,
however there are common points of reference widely accepted
throughout the world to ensure that same environmental standards
apply to both the developing and developed world.
Spectrum has worked on some large projects including for AGIP KCO
on the whole of the FEED stage for the giant $35billion Kashagan
project in the Caspian sea.
Other projects include:
- Zakum Crestal field, for Technip Abu Dhabi, UAE
- Miskar field, Tunisia for Bechtel
- Al Khalij field, Qatar for Nama Mott MacDonald
and Total Fina Elf
- Cawthorne Channel AG project Nigeria, for
Nama Mott MacDonald and Shell
- Kashagan offshore project, Caspian
Sea, for AGIP KCO

Cawthorne
Channel Gas Gathering project, Nigeria |
Spectrum acted as noise consultant on
all the barges and pumping stations, to Shell Petroleum Development
(Nigeria) for the Cawthorne Channel Gas Gathering project. This
project was initiated to reduce the energy waste from flaring
of associated gas.
