Cochran Marine completed the relocation of both the Princess Cruise Lines and Holland America Lines Shore Power Systems from Seattle Terminal 30 to Terminal 91 in 2009. As part of the relocation project, Cochran Marine also designed and developed a Cable Positioning Device (CPD) that is able to adjust to the tide as well as an automation system that allows the Shore Power System to gather connection data and be configured for any vessel in the system’s database with the touch of a button.
We are currently under contract for all Maintenance and Support of the Shore Power Systems including Coordination Studies for the ships, Equipment Testing and Commissioning before each sailing season begins, and weekly Shore Power Connection support when ships dock.
SEATTLE – TERMINAL 30 HOLLAND AMERICA SHORE POWER SYSTEM
Cochran Marine provided Design and Installation services for the Holland America Shore Power project in 2006. The project was very similar in scope to the Princess Cruise Lines project and was located at the same terminal.
SEATTLE – TERMINAL 30 PRINCESS CRUISE LINES SHORE POWER SYSTEM
Cochran was contracted to design and install the first commercial shore power system in the continental United States by Princess Cruise Lines in late 2004. The design and installation consisted of the following: The Primary Switchgear is fed by Seattle City Light at 27.5kV. The Primary Switchgear includes metering equipment and relay protection devices that ensure the safety of the systems and the grid. Power is then fed to the Transformer and from the Transformer to the Secondary Switchgear, which is capable of delivering 6,600 or 11,000 volts of power as needed depending on the class of ship in port. Power from the Secondary Switchgear is fed to a Ground Switch that is connected to the Ship Power Cables that deliver the power to the ship. A jib was installed on the pier to hold the Ship Power Cables and help position them for connection. Since the first installation, many improvements have been made to the jib device, which are seen in more recent systems.
This project was taken from preliminary design through completion in under six months. The environmental impact of the project, the Port of Seattle’s willingness to work with the Cruise Lines and Cochran Marine, and Cochran Marine’s engineering abilities made this extremely condensed schedule possible.
