Applied Acoustic Engineering, which is presently expanding its Great Yarmouth premises, reports an order worth more than £ 100,000 from PGS Physical in Norway for 32 of its 915 series acoustic positioning mini-transponders together with specially designed flotation devices and battery chargers. PGS plans to use them for deepwater surveys off the Brazilian coast for deployment and positioning of seafloor seismic cables at depths down to 2,000m.
CIRIA members, £80 non-members Construction is the largest consumer of natural resources in the UK, soaking up more than 90% of all non-energy materials extracted. This represents some 214 million tons per year of aggregates.
With a choice of beam patterns and compatible with most industry-standard tracking units, 915 systems provide exceptional degrees of reliability and flexibility for operation variously as a transponder, responder or pinger, says AAE. The company has also recently supplied the Indian National Institute of Oceanography in Goa with sub-bottom profiling equipment.
