L-3 SAM Electrical package
Germany’s L-3 SAM Electronics has been awarded a contract to supply the complete electrical package for two offshore supply vessels (OSVs) for Norwegian shipowner, Siem Offshore.
The package includes cable engineering and installation, energy distribution, propulsion, lighting and infotainment systems as well as internal and external communications systems.
L-3’s propulsion system offers four asynchronous motors for main propulsion, five tunnel thruster drives and two retractable thruster drives each driven by an asynchronous motor and speed-controlled low-voltage PWM converter, providing a combined total of roughly 30MW of propulsion power.
For power generation of the four high-voltage 6.6 kV switchboards, eight diesel alternators and motors will be installed along with ten L-3 transformers for onboard low-voltage mains supply.
The contract is the latest in a series of major turnkey projects undertaken by L-3 SAM Electronics on behalf of leading operators in the offshore market. Other recent ventures include outfitting of the heavy-lift jack-up crane vessels, Innovation and Vidar, and Ceona Amazon, a pipelay and construction vessel.
