2T-25m Marine Oil Pipeline Crane
This product is a classification society-certified explosion-proof crane specifically designed for marine oil pipeline maintenance and offshore platform equipment lifting, with the core capability of precisely lifting 2-ton oil pipelines/valves at a 25-meter working radius. Through technologies such as vessel motion compensation, fully sealed explosion protection, and superior corrosion resistance, it overcomes challenges like pipeline alignment and confined engine room operations under vessel sway conditions, ensuring zero-accident safety in offshore oil and gas operations.
Product Positioning and Design Objectives
The 2T-25m marine oil pipeline crane is a high-precision special-purpose equipment engineered for extreme marine operating environments. Its core mission serves two critical scenarios: marine oil pipeline system maintenance and lifting equipment for offshore oil and gas platforms. In complex conditions involving vessel motion, limited space, and flammable/explosive risks, this crane becomes a key device ensuring safe and efficient operation of offshore energy transfer systems, thanks to its classification society-certified explosion-proof certification and engineering-grade reliability.
Core Lifting Capabilities
The crane's primary advantage lies in its precise 2-ton lifting capacity at an ultra-long 25-meter working radius, perfectly matching the lifting requirements for key components such as marine oil pipelines, large valves, flanges, and pump units. Its design fully considers the uniqueness of offshore operations:
- Precision Lifting: Equipped with a high-sensitivity micro-motion control system to meet millimeter-level accuracy requirements for tasks such as pipeline flange alignment and valve installation.
- Load Adaptability: With a rated capacity of 2 tons, it covers the weight range of most standard components in marine oil pipeline systems and commonly used platform spare parts.
- Spatial Coverage: A 25-meter working radius effectively covers ship decks, outer engine rooms, and related platform work areas, reducing the frequency of equipment repositioning.
Three Core Technological Highlights Solve Industry Pain Points
| Technology Name | Key Technical Breakthroughs | Solved Core Problems and Value |
|---|---|---|
| Vessel Motion Compensation | Real-time posture sensing and hydraulic servo active compensation system | Effectively counteracts the effects of vessel roll, pitch, and heave, enabling "land-like" stable lifting on dynamic vessels and solving the problem of inaccurate pipeline alignment. |
| Fully Sealed Explosion Protection | EX d IIC T4 Gb explosion-proof rating, fully enclosed structural design | Prevents contact between electrical sparks and flammable gases, meeting safety requirements for high-risk Zone 1 areas such as engine rooms and oil pipeline zones, achieving intrinsic safety. |
| Superior Corrosion Resistance | Multi-layer heavy-duty anti-corrosion coating + stainless steel/special alloy for critical components | Resists high-salt fog and high-humidity marine corrosion environments, significantly extending equipment service life under harsh sea conditions and reducing maintenance costs. |
Typical Application Scenarios
- Marine Oil Pipeline Maintenance:
- Lifting and replacing damaged pipeline sections while underway or at anchor.
- Removing and installing large valves, filters, expansion joints, and other pipeline accessories.
- Precisely positioning pipeline supports or instrumentation equipment in confined engine rooms or pipe tunnels.
- Offshore Platform Equipment Lifting:
- Transferring equipment, small production facilities, or maintenance tools between platform modules.
- Supporting partial repairs and component replacements on platform superstructures.
- Providing safe and efficient lifting support for material transfer between supply vessels and platforms.
Safety Value: A Solid Guarantee for Zero Accidents
The development of the 2T-25m marine oil pipeline crane directly addresses the most severe challenges in offshore oil and gas operations—how to achieve precise and safe lifting of heavy equipment in dynamic, high-risk, and constrained environments. Its explosion-proof performance, rigorously certified by classification societies, fundamentally eliminates ignition source risks in flammable and explosive environments. Advanced vessel motion compensation technology minimizes lifting uncertainties caused by vessel motion, greatly improving the success rate and safety of fine operations such as pipeline connections. Outstanding corrosion resistance ensures long-term stable operation in harsh marine environments, reducing unexpected downtime or accident risks due to equipment failure. The deep integration of these three technologies collectively establishes a robust technical barrier toward achieving the goal of "zero accidents" in offshore oil and gas operations, significantly enhancing operational efficiency, reducing personnel risks and operating costs, and serving as a critical asset ensuring the safe and uninterrupted flow of offshore energy.
