From the factory to the site, the process of three-stage oil and gas recovery equipment involves several steps, including loading, transportation, unloading, and lifting. Any bumps, tip-overs, or improper selection of lifting points can cause damage to a perfectly intact equipment upon arrival at the site. Whether the equipment company's arrangement in this chain is meticulous directly affects the installation progress and subsequent operation. This article discusses the key points of handling and lifting arrangements as well as the connection matters upon arrival at the site, providing users with a reference for preparation before equipment arrival.
Key points for arranging the handling and lifting process
During the factory production process, the equipment is packaged and secured, with accompanying documents and packing lists accompanying the equipment. During loading, supports are arranged according to the center of gravity, and the equipment is securely bundled. Protective covers are added to pipe orifices, flanges, and instrument parts. Bumps during transportation are inevitable, and the role of packaging is to shield the equipment from these bumps. Unloading and lifting are key actions on site: lifting points must be positioned according to the equipment markings, and it is not allowed to lift on pipe orifices or supports for convenience; before lifting, confirm the positioning direction, foundation location, and surrounding clearance. Lifting in place in one attempt is much more stable than moving it twice.
The user's coordination efforts are mainly focused on three things: clearing the on-site access roads in advance, reserving the crane's parking position, and completing the foundation preparation according to the drawings and verifying the elevation in advance. These three tasks should be completed before the equipment arrives. On the day of arrival, the work will be smooth lifting and positioning, rather than ad-hoc coordination.
Five steps to arrive and take your seat
- On-site inspection: Count the components against the packing list, inspect the appearance for any transportation damage, and record any issues found on the spot;
- Hoisting in place: Lift according to the marked lifting points, align with the foundation, and slowly lower into place to avoid impact;
- Alignment and fixation: Check the level and orientation of the equipment, and complete the fixed connection according to the drawings;
- Interface docking: Process pipelines and electrical circuits are docked according to the drawings, and the interface seals are reviewed one by one;
- Handover confirmation: The installer and the user jointly confirm the in-place status, proceed to the commissioning phase, and handle the handover records.
| link | Key points of arrangement | Common oversights |
|---|---|---|
| Factory loading | Support the center of gravity, tie up firmly, and add a protective cover to the pipe orifice | The instrument part is not protected and was bumped during transportation |
| in transit | The packaging is intact and the accompanying documents are complete | The packing list is missing, leading to disputes during on-site inventory checking |
| Unloading and lifting | Lift according to the marked lifting points and place it in position at once | To facilitate the lifting of the pipe mouth, the flange is deformed due to stress |
| On-site preparation | Road clearance, crane positioning, and foundation verification | The foundation is not completed, and we are just waiting here |
| In place and fixed | After verifying the horizontal orientation, fix and connect | Careless alignment leads to misalignment in later stages |
| Handover and commissioning | Jointly confirm the status and keep the handover record | Oral handover makes it difficult to allocate responsibility for issues |
Wohong's approach to handling, lifting, and installation coordination
Luoyang Wohong Petrochemical Equipment Co., Ltd. implements a full-chain handover for equipment from factory to installation: Before leaving the factory, packaging and protection are inspected item by item, and accompanying documents are complete; upon arrival, installation personnel lead the inspection and lifting for installation, with the user's cooperation and confirmation; basic conditions, access roads, and other on-site requirements are notified to the user in advance in writing for preparation. Lifting, alignment, docking, and debugging are carried out step by step and recorded, and the equipment enters the warranty period with a complete handover file. When users compare and select equipment manufacturers, they can also include "who leads the inspection upon arrival and how the handover is documented" as an evaluation item - manufacturers with clear coordination arrangements will make installation progress and subsequent responsibility division more manageable.
Frequently Asked Questions
What should I do if I find damage on the appearance of the equipment upon arrival?
Deal with it on the spot. First, take photos to record the damage, indicate the condition on the accompanying handover sheet, and then contact the equipment company to determine the handling method. Raising the issue on-site is much clearer than raising it after installation - the responsibility boundaries are immediately apparent, and the handling process is also faster.
What on-site conditions do users need to prepare in advance?
Usually, it includes: the dimensions and elevation of the equipment foundation, the access road and lifting operation space, and the power access point. The equipment company will inform the specific requirements in writing in advance, and it is sufficient to prepare according to the list. For items that are uncertain, directly confirm with the installation supervisor.
Does lifting necessarily require a professional lifting team?
The entire equipment has a certain weight and external dimensions, and it is recommended to be handled by experienced lifting personnel. The selection of lifting points and control of placement are technical tasks. If ordinary personnel are temporarily assigned to handle them, the risk of collision and deformation is high, and the loss in case of any issues will far outweigh the saved lifting costs.
