 Hydraulic BOP Hanging Tools (BOP Handling Systems)

Patented Rig-Floor Handling Solutions | Dual 56B I-Beam Track Installation | Up to 400 kN (40 Ton) Lifting Capacity

Executive Overview

The JSC Series Hydraulic BOP Hanging Tools (Hydraulic BOP Hanging Systems) are patented specialized equipment engineered specifically for the safe installation, dismantling, and rig-floor assembly of wellhead equipment and blowout preventer (BOP) stacks.

Protected under national patent (Patent No. 200520079352.7), the JSC series provides robust mechanical and hydraulic assistance under the rig floor, replacing hazardous manual rigging with precision ground-controlled hydraulics. The system comprises a hydraulic hook and sheave assembly, wireline assembly, a ground-mounted hydraulic control panel, and high-pressure hydraulic piping.

Technical Performance & Engineering Advantages

1. Rig Substructure Integration & Track Mounting

  • 56B I-Beam Track System: The unit is designed to be installed directly onto two parallel 56B I-beam tracks positioned beneath the rig floor.

  • Ground-Controlled Operation: Rig personnel utilize manual control levers on the ground-mounted hydraulic control panel to direct vertical hook lifting/lowering and horizontal traveling movements, ensuring safe positioning away from heavy suspended loads.

2. Heavy-Duty Lifting & Hydraulic Parameters

  • Multiple Capacity Options: Available in four standard model tiers ranging from 200 kN (20 tons) to 400 kN (40 tons) lifting capacity.

  • Controlled Lifting Speed: Engineered with a dual-wire maximum lifting speed of 1.5 m/min for controlled, precise component alignment.

  • Hydraulic Requirements: Operates at a rated hydraulic pressure of 16 MPa (2320 psi) with a rated fluid flow (flux) of 120 L/min (31 Gpm).

Frequently Asked Questions 

Q1: What is the primary application of the JSC Series Hydraulic BOP Hanging Tools?

Answer: The JSC series is engineered specifically to install, dismantle, and assemble all types of wellhead equipment beneath the oilwell rig floor, with specialized capability for handling heavy BOP stacks.

Q2: What are the key structural components included in the system?

Answer: The complete system consists of a hydraulic hook and sheave assembly, wireline assembly, ground-mounted hydraulic control panel, and connecting hydraulic piping.

Q3: How is the hanging tool installed and operated on the rig?

Answer: The unit is installed on two 56B I-beam tracks underneath the rig floor. Operators control lifting and horizontal travel movements remotely via manual control levers located on the ground-mounted hydraulic control panel.

Q4: What are the available capacity models in the JSC series?

Answer: The product line includes four models based on lifting capacity: JSC20/5-A (200 kN / 20 ton), JSC25/5-A (250 kN / 25 ton), JSC30/5-A (300 kN / 30 ton), and JSC40/5-A (400 kN / 40 ton), all featuring a maximum lifting height of 5 meters.
