Introduction
Offshore operations require efficient, modular, and transportable systems to ensure seamless operational continuity. One of the essential platforms that facilitate offshore operations is offshore skids.
In this guide, we will cover the different offshore skid types and specifications that are available in the market. We shall also illustrate the mission-critical role skids play within the oil and gas industry.
What is an offshore skid?
An offshore skid is a modular, self-contained unit designed to support and transport equipment and systems within marine environments— particularly in the oil and gas industry.
Offshore skids can also be employed for various applications, like chemical injection systems, pressure boosting systems, and temporary power generation setups.
In practice, the structural foundation of a skid typically consists of a heavy-duty steel frame designed to withstand harsh marine conditions while providing the necessary support for mounted equipment.
For example, pumps, valves, and piping systems, allowing for easy mobility and installation on offshore platforms.
Unlike conventional offshore installations, skids are highly modular. In fact, their “plug-and-play” nature significantly reduces installation time during relocation in offshore environments that require high mobility and adaptability.
Overall, offshore skids enhance operational efficiency by enabling the pre-assembly of complex systems in a controlled environment before transportation to the offshore site.
Role of skids in offshore operations
Offshore skids play a pivotal role across numerous operations at sea, particularly in:
- Oil and gas production: Offshore skids house critical processing equipment that separates, treats, and prepares hydrocarbons for transport. They’re essential components in production platforms, FPSOs (Floating Production Storage and Offloading vessels), and drilling rigs.
- Chemical processing: Chemical injection skids, treatment systems, and processing units allow for precise chemical management in offshore environments (where space is at a premium and safety concerns are heightened).
- Power generation: Generator skids, power distribution systems, and auxiliary power units ensure reliable electricity supply in remote offshore locations.
The key advantages that make skids indispensable in offshore operations include:
- Mobility: Offshore skids can be easily relocated as operational needs change, maximising asset utilisation and flexibility.
- Efficiency: Pre-assembled and tested units minimise commissioning time, reducing costly offshore installation hours and accelerating project timelines.
- Cost-effectiveness: The modular nature of skids allows for standardisation, simplified maintenance, and reduced overall project costs compared to custom-built onsite systems.
- Space optimisation: In the confined environments of offshore platforms, skids make efficient use of limited space by integrating multiple functions into compact footprints.
Types of offshore skids
Different offshore skids are designed to meet specific industry needs.
Here are the major categories:
Process skids
These skids handle chemical processing, separation, and treatment. Common examples include:
- Gas dehydration skids: These remove moisture from natural gas to prevent pipeline corrosion.
- Glycol regeneration skids: These are used in gas processing plants for moisture control.
- Fuel gas conditioning skids: These ensure a clean fuel supply for turbines and engines.
Equipment skids
These skids house critical offshore equipment essential for various operations. Examples include:
- Pump skids: These are employed for fluid transfer and injection.
- Compressor skids: These facilitate gas compression for transportation and processing.
- Filtration skids: These skids provide essential filtration for fluids and gases.
- Hunting skids : These are used to move and transport hunting equipment to remote or difficult-to-access hunting locations.
Utility skids
These skids provide essential offshore utilities such as power, heating, and cooling. Examples include:
- Generator skids: These provide backup or primary power offshore.
- HVAC skids: Offer temperature control and ventilation solutions.
- Water treatment skids: Ensure a clean water supply for offshore platforms.
Storage and transport skids
Designed for safe transport and storage of materials and chemicals.
Examples include:
- Chemical injection skids: These skids facilitate precise chemical dosing.
- Storage tank skids: These skids securely store fluids and gases offshore.
- Pipe handling skids: Ensure safe transport and storage of piping materials.
Custom-engineered skids
These skids are tailored to meet specific offshore requirements.
- Modular control room skids: These skids consist of portable control rooms for offshore monitoring.
- Temporary power distribution skids: These provide power solutions for remote offshore sites.
Key specifications of offshore skids
When selecting an offshore skid, always look out for the following specifications:
- Material and build quality: Offshore skids are usually made of stainless steel, carbon steel, and corrosion-resistant coatings. The corrosion-resistant coatings enable them to withstand harsh marine environments and extend their lifespan.
- Load capacity and weight considerations: Offshore skids are designed to support significant loads, ensuring structural integrity in offshore conditions. Their load capacities are often specified according to industry standards.
- Compliance and certification standards: Offshore skids should meet API, ABS, ASME, DNV 2.7-1, or EN 12079 standards. These certifications ensure that they meet the highest safety and quality standards for offshore operations.
- Safety features and environmental protection: Most offshore skids include safety features such as fireproofing and explosion-proofing to prevent spills and protect marine ecosystems.
- Integration with offshore systems: Offshore skids are designed for compatibility with existing offshore platforms, piping, and power systems. This interoperability ensures seamless functionality in offshore environments.
