What is an Offshore container? Understanding Offshore containers
The European Committee for Standardization EN-12079:2006 standard defines an offshore container as a portable unit designed for repeated use in transporting goods or equipment to, from, or between fixed and floating offshore installations and ships. Offshore containers also encompass containers and portable tanks used for transporting dangerous goods. They can be categorized into three types based on their purpose and design:
- Offshore Goods Containers: These containers are built explicitly for transporting goods and can include various types, such as general cargo containers, cargo baskets, unique containers, boxes, gas cylinder racks, and offshore portable tanks. Offshore portable tanks are utilized for transporting dangerous goods and must comply with the International Maritime Dangerous Goods Code (IMDG).
- Offshore Service Containers: Offshore service containers are custom-built containers designed for specific tasks that are typically temporary. They are tailored to meet specific operational requirements. Such containers include labs, workshops, control stations, and other specialized units.
- Offshore Waste Skip: An offshore waste skip holds waste materials. Depending on the specific waste disposal needs, it can have an open or closed top. These skips are commonly employed in offshore operations to manage and transport waste generated on offshore installations.
Offshore oil and gas containers are often called "skids." They are frequently used for transporting significant components to drilling and production rigs. These skids can vary in complexity, ranging from simple frames that hold the contents to more intricate structures. The skid, along with its contents, is sometimes referred to as a "skid package."
Difference between ISO Containers and Offshore Containers:
Offshore containers differ from ISO freight containers in several ways:
- Exposure to Harsh Environments: Offshore containers are frequently exposed to open seas on the decks of supply vessels and are loaded onto platforms in harsh weather conditions. Therefore, they are designed to withstand extreme environmental factors.
