Siemens to Power PSV Pair

Bay Shipbuilding in Sturgeon Bay, Wis., has awarded the Siemens Division Industry Solutions a multimillion Euro contract to equip two platform supply vessels (PSV) with a diesel electric propulsion system. The ships are being constructed by Tidewater Marine LLC, a Tidewater Inc. subsidiary. They are slated for delivery in the fourth quarter of 2012 and the second quarter of 2013 respectively.
Siemens will outfit two new PSV of Tidewater Inc. with a Bluedrive multi-drive low-voltage

propulsion system. It is designed to improve reliability due to failsafe features that will help the vessel owner lower maintenance costs, increase efficiency and operational ease

for the vessel and crew. The Siemens scope of supply also encompasses the main

generators, main propulsion and thruster motors, switchboards and power management

system. The ship’s automation system Siship IMAC will perform monitoring, alarm and

control functions for the electrical equipment on board. Furthermore Siemens will

install a unique, fully integrated electrical fire-fighting system, and is

responsible for designing, engineering, commissioning and the project management of

the diesel electric and automation system.
Designed to carry a wide variety of cargoes, the two new PSVs can transport

substantial amounts of fuel, water, drilling fluids, and dry bulk in below-deck

tanks, while simultaneously transporting casing, drill pipes and containers on
open-decks. Certified by the American Bureau of Shipping, each PSV will measure 92.5 x 19 m. They will be capable of speeds of more than 14 knots.
