Instrumentation/Control Systems Sample Clauses

Instrumentation/Control Systems. TANK CONTRACTOR shall recommend the necessary instrumentation and controls required to safely operate and protect each of the storage tanks. These recommendations shall be submitted to PURCHASER and shall include, as a minimum but without limitation, the following: • Tank Data Acquisition System (see below); • Tank wall temperature sensors (Cool Down); • Tank bottom temperature sensors (Cool Down); • Outer tank floor and suspended deck low temperature sensors; • Density/level/temperature sensor (servo type); • Tank level sensors (redundant, servo type); • High level switch; • Tank pressure transmitter (redundant); • Tank temperature profile sensors; • Vapor space temperature sensors; • Inner tank movement monitoring system; • Tank pressure/vacuum relief valves.** ** It is the TANK CONTRACTOR’s responsibility to size the pressure/vacuum relief valves. All electronic instruments shall be designed and wired to TANK CONTRACTOR-supplied junction boxes located at grade, 20 feet horizontally from the base of the tank (i.e. within the Battery Limits) and include: • Cable trays and supports; • Installation materials, including cables, tubes, conduits, junction boxes, etc. TANK CONTRACTOR shall provide calculations and certification for pressure/vacuum relief valves. TANK CONTRACTOR shall be responsible for installing control valves and other instrumentation shown within the boundary limits of TANK CONTRACTOR’s package on the referenced P&ID’s. TANK CONTRACTOR shall clearly identify the location and physical interconnection of this equipment on approval drawings submitted to PURCHASER. TANK CONTRACTOR shall design and supply running instrument air sub-headers (with isolation valves for take-offs) from TANK CONTRACTOR Battery Limits to those areas requiring this service. TANK CONTRACTOR shall perform calibration tests for all instruments provided by TANK CONTRACTOR or any Subcontractor or Sub-subcontractor for the Phase 2 Tanks. TANK CONTRACTOR shall provide additional gas detection instrumentation to cover the air gap below the elevated slab. A minimum of 8 gas detectors per tank shall be furnished. The gas detectors shall be wired to the junction boxes at the Battery Limits. TANK CONTRACTOR shall provide complete and comprehensive testing procedures for all equipment and systems provided. TANK CONTRACTOR shall develop as part of this Scope of Work the following information, as a minimum but without limitation: • ISA (Instrument Society of America) data sheets for a...
