About this file
This document contains questions and answers regarding Solicitation 6933A220Q000014 for upgrading the electrical distribution systems at offshore platforms located at the James River Reserve Fleet in Fort Eustis, Virginia. Key details include that the contractor will be responsible for stripping out and disposing of unused equipment in all existing switchgears. New switchgears will have only four switching ways and protection settings will match those of platforms 3 and 6. The government will provide and install an Adalet plug for the existing marine cable on platforms 4 and 5. The contractor must submit engineered construction drawings showing all modifications and equipment, though these do not require an engineer's stamp. Remote monitoring of phases, voltage, amps and wattage is listed as an option but an existing system may not support medium to high voltage monitoring.

If available, remote power monitoring shall be accessible via a website or server side software, and be able to monitor phases, voltage, amps and wattage of incoming feeds to switchgear. This can be either through cellular updating with wired or wireless devices on feeds, or by line-of sight back to facility.
8. Is there an existing system that can be utilized for this monitoring?
We have not researched, procured, designed or used this technology before with Medium to High Voltage power. We do already have Remote Monitoring Software and System for secondary voltages (440 VAC – 120 VAC in use) by Monnit, LLC onboard ships and the facility http://www.monnit.com If this technology is not available, then since it is listed as an option, it shouldn’t be included.
9. Is the contractor required to provide an engineered set of construction drawings and specifications? If so, do these need to be stamped by an Electrical Engineer. If not what type of details are required.
Yes, this is included in the Documentation portion of the Statement of Work. All modifications to the existing platform stations and wiring should be placed on an engineered set of construction drawings. The drawings should show all enclosures, terminations, wire sizes and notes listing what has changed to existing platform and what equipment parts were used. It does not have to be stamped by an Electrical Engineer.
