How can the surface protection of drilling equipment be prepared and operated?

The manner in which the surface protection of drilling equipment is to be carried out is to be judged first and foremost by the separation of vehicle traffic, stationation of equipment from the support of the crane. With regard to the construction of drilling platforms, the relocation of equipment, the supply of materials and the auxiliary hang-up sites, the topic focused on “how to prepare and operate the surface protection of drilling equipment”, which usually goes through multiple stages of entry, construction, overhaul and evacuation, and changes in the water content and traffic on the ground. The most easily ignored of this topic is the drop in ground-based loads and the emergence of pump muds or faults following rainfall. The problem of grass-roots and drainage may have expanded if only ad hoc slabs were added after a vehicle has been trapped.

The technical communication should first identify the control design of the driller module, the transport vehicle axial load, the tracked size, the retroactivity of the crane leg, the equipment set-up, the underground facility, the site endurance and the conditions of the rainy season. It is proposed that the line segments, turn areas, docking slots and surfaces be counted separately, and that suppliers be required to describe the materials, the finished goods, the test methods, the basis of application and the conditions of operation. Reference data such as nominal 50 to 200 tonnes cannot be directly compared horizontally without the same test basis. With regard to “how to lay and run a test exercise for ground protection of drilling equipment”, the information review should also distinguish vehicles by axle-load from tyres, not replacing all inputs with total weight, and include missing information as an item to be confirmed in the quotation and construction programme.

In the absence of space on the ground, work cannot be undertaken by reducing the necessary cover or moving legs to the shoulder of the road. Stations and construction should be reordered to provide sufficient space for “counting the line segments, turn areas, docking positions and surfaces, respectively”. The rigs shall distinguish between vehicle access, stationing of equipment and cranes, and the pavement shall be responsible for the protection of the ground and the mats shall be accounted for on the basis of maximum reversibility and durability. Any forced overlays of holes, temporary mats or uncounted should be returned to the technical manager for evaluation. The trial-pail record of “how the surface protection of drilling equipment is to be done” should identify the starting and ending position, vehicle condition and release conclusions to facilitate review as construction conditions change.

Special inspections should be added after extreme weather, equipment anomalies or route adjustments. Use of position markings and fixed view photographs for track tracks, permanent deformation of the plate, leg deposition, courtyard drainage, soft spots, connectors, mud contamination and horizontal levels to facilitate comparison of sedimentation and shift. Cleaning the surface of polymers avoids fire, sharp shovels and violent knocks, creating new cracks and stress concentrations. The inspection forms, which revolve around “how the surface protection of drilling equipment is to be prepared for trial and run”, are to show a separate line of surface-based loads reduced after rainfall and changes in pump mud or error stage, with an indication of the repeater and the time of return.

For oil and gas projects that are ongoing or duplicated, a baseline can be established for each square metre of work-hours, vehicle cycle, cleaning time, damage rate and restoration costs. This would make it easier to identify whether the next offer and inventory planning, which is no longer based solely on experience, is repeated in a given season, when ground-based load decreases after rainfall and pump muds or faults occur. It should also answer whether the “how the surface protection of drilling equipment is to be prepared and run” has been improved by calculating the straight-line segment, the turn-off area, the docking position and the surface area separately, so as to avoid a subjective description of the final item.

This paper could serve as a technical discussion list for the hydrocarbon project, but not as a separate construction permit. The project will also require a written programme of transport organization, temporary structures, electrical safety, fire protection, weather emergencies and site restoration systems, and a review of key carrying and stabilization conditions by authorized personnel.

The following special verifications should be carried out in connection with the construction of the rigs, the relocation of equipment, the supply of materials and the auxiliary hanger site, as well as with respect to the “drying and commissioning of the surface protection of drilling equipment”, the following: the test pavement shall select the softest floor and the most representative heavy vehicle, and shall record the vehicle's state, velocity, wheel, plate change and post-rain rainfall. The test operation is not considered to be permanent and will still need to be revalidated after the vehicle has become heavy, its route has changed or the weather has deteriorated.

Recommendation on on-site implementation: Test-run records should indicate temperature, weather, ground state, vehicle load, tyre pressure and speed. When the subsequent conditions go beyond the scope of the test, the original conclusion automatically lapses, requiring a further inspection or approval of the change by the project technical staff.
