This guide introduces a PowerLink diesel-driven screw air compressor specifically designed for offshore operations. Mounted within a DNV 2.7-1 certified lifting frame, this compressor is designed to ensure safe operation during offshore transport, lifting, and long-term operation in corrosive marine environments. We will explore its key features, offshore applications, and why this configuration is becoming the preferred solution for modern offshore projects.
Why Offshore Operations Demand Specialised Air Compressors?
Operating offshore is fundamentally different from onshore industrial applications. In the open sea, equipment is subjected to a relentless barrage of environmental and operational stressors that would cause standard industrial compressors to fail prematurely.
To maintain operational uptime, offshore compressors must be engineered to withstand:
- Corrosive Environments: Constant exposure to high-salinity salt spray and extreme humidity.
- Structural Stress: Intensive platform vibrations and high-velocity wind loads.
- Logistical Rigor: Repeated crane deployments and vessel-to-platform transfers.
- Compliance Hurdles: Strict maritime safety standards and rigorous lifting regulations.
- Limited Serviceability: Restricted access for emergency maintenance in remote locations.
Overview of the PowerLink Offshore Air Compressor
At the core of this solution is a diesel-driven screw air compressor capable of delivering 30–1600 CFM with working pressures from 7 to 35 bar, making it suitable for a wide range of offshore tasks
Unlike electric compressors that rely on stable grid power, diesel-driven units offer complete independence, a major advantage for offshore platforms where power availability may be limited or reserved for critical systems.
Key characteristics include:
- High-output screw air end for continuous duty
- Robust diesel engine options (Cummins, Kubota, CAT, etc.)
- PLC-based intelligent control system
- Heavy-duty enclosure designed for harsh outdoor use
- Mounted within MDNV 2.7-1 Certified Lifting Frame
DNV 2.7-1 Certified Lifting Frame: Safety Comes First
The air compressor is installed inside an Offshore Shipping Containers Equipment Lifting Frame that is designed and certified in accordance with DNV 2.7-1.
DNV 2.7-1 is an internationally recognized standard for offshore lifting frames and containers. It defines strict requirements for:
- Structural strength
- Dynamic load resistance
- Lifting point design
- Impact and fatigue performance
- Offshore crane handling safety
By integrating the air compressor into a DNV 2.7-1 certified lifting frame, the entire system can be safe:
- Lifted by offshore cranes
- Transported by supply vessels
- Moved between decks and platforms
- Operated without compromising structural integrity
This is critical for offshore drilling platforms, where equipment may be lifted dozens of times during its service life.
Designed for Offshore Transportation and Lifting
In offshore operations, equipment handling is a high-stakes logistical challenge. Our air compressor systems are engineered with a specialized lifting frame designed to facilitate seamless transport across a variety of maritime deployment scenarios.
To ensure maximum operational flexibility, the system supports multiple certified lifting configurations:
- Four-Point Sling Lifting: For balanced, high-stability vertical hoisting.
- Spreader Beam Integration: To accommodate wider lift spans and prevent structural compression.
- Dedicated Crane Hook Points: Optimised for rapid vessel-to-platform transfers.
- Integrated Forklift Pockets: Specifically designed for secure manoeuvring on deck or within storage facilities.
Prioritising Stability and Personnel Safety
A critical feature of our offshore lifting frame is its optimized center of gravity. By neutralizing the risk of unpredictable swinging or tilting during hoisting, we eliminate potential hazards to personnel, vessels, and platform infrastructure.
In the demanding world of offshore logistics, safety margins are the ultimate metric of value. While high air output is essential, a system’s true worth is defined by its ability to be shipped, lifted, and positioned without compromise. At PowerLink Energy, we build for the lift, ensuring your equipment arrives ready for performance safely and efficiently.
Corrosion Resistance for High-Salt Marine Environments
Salt corrosion is one of the leading causes of equipment failure in marine environments. To mitigate this risk, the air compressor and its mounting system are constructed with corrosion-resistant materials and advanced protective coatings, specifically designed for marine environments.
The system features a marine-grade steel structure, comprehensive anti-corrosion surface treatment, and weatherproof enclosure panels. All electrical cabinets are fully sealed for rain and dust protection.
Furthermore, critical components, including radiators, control cabinets, air filtration systems, and piping, are meticulously protected to withstand prolonged exposure to the high salinity of the marine environment.
This robust design ensures reliable operation of the equipment in harsh marine conditions, significantly reducing maintenance frequency and extending overall service life. These two points are crucial for offshore operators, as unplanned downtime can result in extremely high costs.
Reliable Performance in Harsh Offshore Conditions
The PowerLink diesel-driven screw air compressor is designed for continuous operation under heavy load, making it ideal for offshore environments where equipment may run for extended periods.
Key performance features include:
- Twin-screw rotors with high volumetric efficiency
- Low oil content in compressed air (approx. 3 ppm)
- Advanced air-oil separation system
- Large-capacity fuel tank supporting 8+ hours of operation under full load
- Efficient cooling system suitable for high ambient temperatures
The compressor also features real-time monitoring and protection systems, including automatic alarms and shutdown functions for abnormal conditions such as overheating, low oil pressure, or system faults
Intelligent Control and Offshore-Friendly Operation
Offshore crews value simplicity and reliability.
This air compressor uses a PLC-based microprocessor control system that provides:
- Real-time monitoring of operating parameters
- Clear display of pressure, temperature, and runtime
- Multi-level warning and protection logic
- Emergency stop functionality
The system is designed for easy operation with minimal training, an important advantage in offshore environments where crews rotate frequently.
