About this file
This is an addendum to a Request for Proposal issued by the Connecticut Port Authority for long lead electrical equipment supporting the New London State Pier Shore Power Project. The addendum provides detailed technical specifications for electrical infrastructure modifications required to enable docked marine vessels to connect to the local electric grid. The project encompasses modification of an existing high-voltage shore power outlet at the southern station and installation of additional high-voltage and low-voltage shore power outlets on the northern berth side. Key technical specifications include the procurement of a vessel-mounted switchboard (P-32, 3 section, pad mount, 1600A) with distribution sections, along with conductor routing and reuse of existing electrical components from decommissioned transformers and infrastructure. The addendum contains detailed keynotes specifying the pulling and routing of existing conductors (#2/0, #1/0, and #600 gauge) from decommissioned transformers T-21 and T-22 to new transformer installations T-01 and T-02, as well as connections to switchgear and panel boards. The addendum also specifies transformer impedance ground requirements with a neutral ground resistor rated at 26 ohms and minimum rating of 15A for 5 seconds and 5A continuous.
The addendum is marked "NOT TO BE USED FOR CONSTRUCTION," indicating it represents preliminary design documentation. No pricing information, set-asides, incumbent contractor details, or contract term specifications are provided in this technical addendum. The document was prepared by Moffatt & Nichol and submitted by an unspecified submitter, with the drawing scaled at 1:1 on the sheet. Vendors responding to the underlying RFP should reference the complete solicitation documents available through the Connecticut Port Authority website for comprehensive procurement details, evaluation criteria, pricing instructions, and submission requirements.
