This contract includes scheduled on-site reviews of the Company’s process and the Compressor Controls Corporation control system by one of the Contractor’s Field Engineers to determine if any degradation or changes have occurred. If required, the Contractors Engineers will retune or reconfigure the Compressor Controls Corporation control system to match the Company’s equipment and process conditions.
The Contractor will make any spare parts upgrades or software enhancements/revisions that may be required, during the Contractors periodic scheduled on-site visits unless otherwise agreed with the Company. Any assiciated costs with a software revision, software upgrades or license renewal will be billled separately. All modification including parameter changes must have specific company approval.

Coverage
The Preventive Maintenance Service Module OnSite-PM covers one or two trips per year with days on site to be decided by the customer. Each trip will include preventative maintenance activities as described in this section. Necessary overtime hours caused by activities not covering the preventive maintenance activities (e.g. delays) will therefore be charged on a reimbursable base against the applicable Services Rate Sheet. Travel and living costs are not included in the Contract price and will be billed separately as per the Service Rate Sheet. The annual visit dates and work scope must be mutually agreed between the Contractor and the Company and be scheduled 30 days in advance.

Reporting
The Contractor will submit a Field Service Report after each onsite visit.

Unplanned Visits
Should an unplanned site visit be required by one of the Contracts Field Engineers (ie emergency shutdown, unscheduled maintenance, etc) the Contractor must give
consideration to making that visit a scheduled OnSite-PM. The company will make this request in writing. If it is not possible to do so, then the rates for this unscheduled visit are as per the Services Rate Sheet.

Preventative Maintenance Introduction
The optimum site condition to execute (preventive) maintenance of CCC equipment is during a planned shutdown of the turbo-machinery train. Preventive maintenance with train in service/operation without risk of unexpected shutdowns is hardly possible and should be avoided.

The maintenance activities for a CCC control application can be separated into the following parts:
1. CCC Control System/Equipment;
2. PC Based CCC Support Software;
3. Involved Field Instrumentation and Control Elements.

Preventive Maintenance Activities
Scope of maintenance activities is in general the same for various CCC control systems.

Activity
Verify/Calibrate Analog I/O – To ensure that AI and AO are to specification. AI’s are checked with current source connected to inputs. AO are checked with multi-meter in series with field load. See also Chapter 6 of Hardware Reference Manual IM300/H for more details.

Test Discrete I/O – To validate correct operation of digital inputs and outputs. In and outputs will be tested with controller terminal connectors disconnected. See also

Chapter 5 of Hardware Reference Manual IM300/H for more details.

Verify Existing Configuration – Compare controller parameter checksums with configuration stored in the CCC Amsterdam Office and clarify any potential differences.

Test Serial Communication w Host(s) – To prove controller serial communication ports.

See also Chapter 5 of Hardware Reference Manual IM300/H for more details.

Redundant Switching – Switch from MAIN to BACK-UP and vice versa to check for any latent failures in back-up controller and redundant switch.
