5.03.002 Disconnection or Removal of Production Hoses (Suction, Discharge, Fuel gas) on Flogistix Skids

This Policy is completed waiting on Field Service, Engineering & Safety approval.

Purpose

The purpose of this document is to establish the minimum requirements for the removal of Production hoses connected to Flogistix compressor or pump packages with hoses being used for Suction, Discharge or Fuel Gas applications. This Policy is effective for all Flogistix compressor packages with Hose connections for Suction, Discharge or Fuel Gas that is being manufactured, ran on Test Loop, maintained, or being contracted to work on by Flogistix personnel in the Field or shop locations. Where the use of high pressure hose is required in lieu of hard piping the Suction, Discharge, or Fuel Gas from the Flogistix package to Production equipment.

Procedure

This procedure applies to all Flogistix packages where the removal or disconnecting of high pressure hose that is being used for Suction, Discharge, or Fuel Gas applications that are currently in service in the Field, Test Loop, at a Repair Shop. Flogistix Service Technicians will perform the task of properly removing or disconnecting high pressure hoses from any Suction, Discharge or Fuel Gas hose as laid out in this procedure.

Before any work is performed a JSA needs to be done according to Flogistix procedure along with any Customer requirements before any work is started.

Any time a high pressure hose is being used for Suction, Discharge, or Fuel Gas needs to be disconnected or removed great care must be taken to insure all pressure has been relieved from the hose. Failure to relieve the pressure from the hose when disconnecting could result in minor to major injuries or up to including death to any individual(s) within the hoses vicinity and can also result in minor to major property damage. Hoses disconnected on one end unrestrained with high pressure can have a lot of power to try to restrain. It is highly recommended that any hose being used for a high pressure application have a Hose Whip Check restraint on each end of the hose. The use of a Hose Whip Check give standby restraint to the hose end when installed correctly. Hose Whip Checks when installed correctly on one end will extend across the hose fitting and the other end of the Hose Whip Check is attached to to the piping where the hose is connected.

See below for a sample of a Hose Whip Check

Before removing any high pressure hose the internal pressure of the hose must be relieved of all pressure until the pressure of the hose equals ambient pressure.

Before attempting to relieve the internal pressure of any hose the pressure sources going into and down stream of the hose must be closed and secured to make sure pressure can not be reintroduced to the hose by mistake.

Follow proper Flogistix Lock out Tag procedure according to SECTION 09 - Performing Work Safely on the Safety Wiki. Once pressure sources to hose have been isolated, and valves blocked, the hose unions can then be loosen but not removed.

Unions halves need to be only taken loose enough to where the hose can be moved or wiggled within the union halves to verify pressure has been relieved from hose.

**Hammer unions and wrench unions can vary from various manufactures on how many turns it takes to fully disconnect the union halves.

If the hose has pressure when the union halves are loose, pressure should be heard being relieved around the union half, and there should also be resistance when trying to move or wiggle the hose.

Once all pressure has been verified that the hose is free of any pressure the union halves can be loosened until the hose is disconnected from the source.

Once a hose has been disconnected it should still be treated as if there could be trapped pressure inside of hose.

Unsuspecting pressure trapped in a hose could be from a foreign object, freeze or from a hydrate of some production fluid. It is recommended to stay clear from the end of the hose in the event that any unrelieved pressure does not blow pressure or a foreign object from the end of the hose.

Responsibilities

Management - Management is responsible for implementing, supporting, and enforcing the requirements of this procedure to their respective locations/area.

EHSS - Responsible to assist in the implementation of this procedure and to review for effectiveness.

Employees, Contractors, Vendors, ETC. - Are responsible to follow the requirements outlined in this procedure and ask for assistance

Scope

This procedure applies to all Flogistix compressor packages with high pressure Hose being used for Suction, Discharge or Fuel Gas from the Flogistix package to Production equipment and is applicable to all Flogistix employees, contractors, and temporary employees.

Hazards

Employees should be aware that units could contain flammable and toxic gasses. Potential for the possible hazards of gas ignition or fire, hot surfaces & fluids, rotating equipment. Risk of possible concentration of H2S. Hazardous gases could be in the units pressure vessels, cooler, or associated piping and risk of inhalation of hazardous gas fumes.

Safety

All Personal Protective Equipment (PPE) for normal Field Mechanical duties apply for this procedure.

Four Gas Monitor, which is outlined in the Flogistix EHSS Manual, PPE Section 8, Procedure 8.3

Lock Out Tag Out LOTO which is outlined in the Flogistix EHSS Manual, Section 9 Procedure 9.11

This procedure applies to all units in service in the field, at a service shop, or in any storage yard.

Insure Flogistix personnel have proper safety certification or site orientation if required by the Flogistix Customer.

Insure Flogistix personnel adhere to all Customers safety practices.

Training

All employees shall be initially trained on the following topics:

Employee Personal Protective Equipment (PPE)
Lock Out Tag Out (LOTO) procedure according to Flogistix policy
Emergency and First Aid procedures
Methods and Observations that may be used to detect the presence or release of a hazardous chemicals or gas in the work place

Tools & Equipment Required

All employees performing this procedure shall be required to have the listed tools to perform job tasks:

All required PPE according to Flogistix Safety Policy
Brass Hammer to be used if a Hammer Union is installed on the hose end.
Proper size Pipe Wrench if a Wrench Union is being is installed on the hose end.
