Figure 1 – FCP Vs TPE Decision Tree

1. Equipment that is to be installed and maintained for a period greater than 12 months will not usually be considered as Temporary.

2. If the plant has been designed to accept the additional equipment in such a manner that the equipment will become part of the plant then it will not be considered Temporary.

3. If interfacing the equipment with the existing plant requires additions or modification to the plant, then it will not be considered temporary.

4. Equipment that is not to be kept onsite at the end of the working day shall not be considered as TPE (no necessity to register) but it shall still be required to carry the maintenance and inspection certification where appropriate.





3.3 Temporary Portable Equipment Registration Process

The following process briefly illustrated below shall be used to register TPE at a facility.

TPE may be required to be installed on-site for any of the following reasons;

Temporary back-up or standby for fixed installation e.g. generators, air compressors etc;

Provide support for undertaking maintenance or repair e.g. floodlights mounted on power generator, forced draught fans for ventilation or extraction; pumps etc;

Provide support for temporary installations e.g. temporary accommodation etc;

Appendix 2 – Temporary Portable Equipment Register

The TPE Register is typical and can be reproduced for any facility.





Appendix 3 – Guidelines for Use of Portable Diesel Engines

1. General specifications which shall apply are:

The person requesting or expediting the diesel engine for use on site will be the focal point for all communication with the supplier / vendor of the TPE;

The person requesting or expediting the diesel engine will ensure that the equipment is suitable for the planned use;

The supplier / vendor of the diesel engine will provide a safe and reliable unit which complies with the requirements of this procedure;

The documentation detailed in Section 3.1 of this procedure shall be provided with the diesel engine and accompany the unit at all times;

The supplier / vendor of the diesel engine shall undertake pre-delivery checks are to cover all requirements of Section 3.1;

The diesel engine shall be checked by person requesting or expediting, or his / her delegate to ensure conformity to requirements prior to the diesel engine being installed on-site;

An inspection of the diesel engine must be carried out on the relevant discipline CFDH or his delegate and by the responsible electrical person prior to connecting to the facility / station shutdown system (if applicable);

PTE associated with PTW shall be inspected by the Permit Applicant and the Responsible Supervisor prior to use and thereafter at intervals not exceeding one working week (5 days). The inspection checklist shall be kept with the diesel engine;

Suitable guard rails and shields shall be fitted, where required, to protect operators from moving parts e.g., drive shaft, cooling fans, etc;

Consideration should be given to the provision of adequate ventilation;

2. Diesel Engines for Use in Non-hazardous Areas

The minimum requirements are as follows:

General appearance - the units are to be well maintained, clean and with no oil/fuel deposits within the container;

The exhaust system shall be leak free and this, along with any associated acoustic insulation, shall be free of any combustible materials;

Drip trays shall be provided to contain fuel oil or lubricating oil spillage. For containerised units, this should take the form of a fixed metal tray situated under the machine, complete with drainage facility. For open units, a floor mounted metal tray is acceptable;

All fuel lines shall be fire resistant;

An easily accessible fuel tank isolation valve shall be fitted;

All fan belts shall be fire-resistant anti-static type (FRAS);

The cooling fan shall be a non-metallic type, adequately guarded;

The battery, if fitted, must be in good condition - fully charged and adequately secured with permanent clamps;

All electrical connections shall be sound and tight;





The electrical insulation integrity shall comply with the requirements of current IEE Regulations;

All metal work is to be effectively electrically bonded together. Purpose bonds (6mm-2 minimum) stranded PVC covered cable are only required across insulated sections e.g., anti-vibration mounts. Elsewhere, fortuitous bonding via metal to metal contact is acceptable;

Two earthing terminals (size M12) shall be provided at diagonally opposite ends of the base frame. These is to be clearly identified and suitably mounted on the main frame of the units large enough to take both the welding earth lead (if appropriate) and the installation earth bonding cable;

If the unit is a welding set, the welding cables supplied are to conform to BS 638, Pt.4;

A certified spark arrester shall be provided for the exhaust system. Preference shall be given to the fitting of a `cyclonic' type as opposed to the `filter' type which requires considerably more maintenance;

An air inlet shutdown valve (Rig Saver), to prevent over speeding of the unit on gas ingestion, shall be fitted and its operation should be independent of the engine. This device is to be checked for operation at the pre-delivery checks and the cut-off speed recorded in the engine log-book;

An emergency stop shall be fitted, which must be easily accessible from outside the unit and suitably protected to prevent inadvertent operation. The operation of the emergency stop shall be verified at the pre-delivery checks and during hook-up on site;

NOTE: The battery ammeter charge/discharge State should be checked with the unit Stationary to ensure no leakage current Exists.

3. Diesel Engines for Use in Zone 2 Hazardous Areas

All temporary diesel engines for use in a Zone 2 area shall comply with the requirements of 2 above, and the following:

All plant shall be Zone 2 certified;

The maximum surface temperature is to be no greater than 250OC (or where

temperature class is specified, Class T3);

Fitted with an inlet flame arrester (flame trap);

The unit shall be attended at all times or fitted with a device which will automatically stop the machine on a change of site conditions;

An inlet shut-off valve which should automatically operate on;

- High exhaust gas temperature.

- Engine overspeed.

- High coolant temperature.

- Low lubricating oil pressure.

Fitted with an exhaust flame arrester (flame trap);

The starting system shall be non-electric, i.e. hydraulic, pneumatic or mechanical.

IMPORTANT NOTE: Spring coil inertia starters must be certified for hazardous areas.

Any ancillary electrical equipment e.g., gauges, to be appropriately certified for use in hazardous areas.





4. Cases Where Automatic Shutdown Should Not be Used

Where the diesel engine under consideration is that of a portable crane, fork lift truck, or a unit involved in critical Well Servicing activities, then no automatic shutdown due to a change of site status shall apply, thus allowing manual shutdown by the unit operator,

but the units must be continuously manned throughout these operations.

High exhaust temperature, low lubricating oil pressure and high coolant temperature should alarm only, allowing manual shutdown by the unit operator. This is to ensure that there is no direct unwanted interference during a critical operation. The overspeed shutdown, however, shall be automatic.

For critical Well Servicing operations, and with the prior agreement of the Production Coordinator, when a change of status occurs shutdown shall be instructed by the person in charge of the worksite, who must be in contact with the Control Room at all times.

NOTE: Typical critical operations where diesel plant is used in Well Operations include, but are not limited to, wireline winches, coiled tubing units, nitrogen converters and pumping units performing operations like acid jobs, sand fracs, sand clean-outs and circulating through coiled tubing.
