Northrop Grumman Corporation (NOC)
has received orders from SRH Marine Electronics SA
of Piraeus, Greece
, to supply more than 60 simplified voyage data recorders (S-VDRs) for Greek shipowners to meet International Maritime Organization
(IMO) regulations requiring S-VDRs on existing merchant ships by July 1, 2007.
Northrop Grumman’s Sperry Marine
business unit will supply the S-VDR systems and will assist SRH Marine to oversee installation, integration, commissioning and annual performance testing of the systems through its worldwide service network
The S-VDR orders include 23 ships owned by a Greek container ship operator, with the remainder distributed among a number of other Greek shipowners.
Similar to an aircraft’s “black box” cockpit recorder, the S-VDR downloads data from the ship’s navigation instruments and voice recordings from the bridge and radio communications
, which can be retrieved and analyzed following an accident at sea.
The Sperry Marine S-VDR system has been type-approved by major classification societies and national authorities to comply with IMO and International Electrotechnical Commission specifications
. The IMO carriage requirements state that all existing ocean-going ships over 3,000 gross tonnage must be fitted with an approved S-VDR at the first scheduled drydocking after July 1, 2007, but no later than July 1, 2010.
