Offshore tank containers are used worldwide for the safe transport and storage of liquids in the offshore oil, gas, energy and chemical industries. Unlike standard ISO tank containers, offshore tanks are designed to withstand the harsh conditions found on offshore platforms, vessels and drilling installations. Therefore, both the tank and all components must comply with strict international safety standards, such as DNV 2.7-1 and EN 12079.

At TK Guard, you will find an extensive range of offshore tank container parts, valves and spare parts for maintenance, repair and replacement. From ball valves and pressure relief valves to manlids, airline valves and bottom outlet valves: we supply reliable components for safe and efficient offshore operations.

What is an Offshore Tank Container?

An offshore tank container is a specially designed tank container for the transport and storage of liquids in offshore environments. These containers are used on oil and gas platforms, offshore wind farms, supply vessels and other maritime installations where safety, reliability and durability are essential.

Offshore tank containers are used for the transport of:

• Chemicals
• Drilling fluids
• Aviation fuel
• Lubricating oils
• Fuels
• Produced water
• Industrial liquids
• Environmentally hazardous substances

Due to the extreme conditions at sea, all components are designed for maximum corrosion resistance, mechanical strength and long-term reliability.

DNV 2.7-1 and EN 12079

Offshore tank containers must comply with international regulations specifically developed for lifting and transport equipment used in offshore applications.

The most recognized standards are:

• DNV 2.7-1
• EN 12079
• IMDG Code
• ADR (depending on the application)

These standards set high requirements for the construction, safety and reliability of both the tank container and the valves and accessories used.

Guard Europe Components for Offshore Tanks

An offshore tank container consists of various safety-critical components that work together to safely store, transport and transfer liquids.

At TK Guard, we supply among others:

Ball Valves

Ball valves are used to quickly and reliably shut off product flows. Thanks to their quarter-turn operation, they are easy to operate and provide excellent sealing performance, even under demanding offshore conditions.

Pressure Relief Valves

A pressure relief valve prevents the pressure inside the tank from exceeding the permitted design pressure. When the set pressure is reached, the valve automatically opens and closes again once the pressure has returned to a normal level. This is an essential safety component of every offshore tank container.

Airline Valves

Airline valves regulate the air supply during loading and unloading operations of the tank container. They help prevent vacuum and overpressure situations and can be used in combination with vapour recovery systems. For offshore applications, these components are often manufactured from high-quality 316L stainless steel.

Manlids

Manlids provide access to the tank container for inspection, cleaning and maintenance. A high-quality manlid cover ensures reliable sealing, a long service life and safe maintenance of the tank.

Bottom Outlet Valves

Bottom outlet valves are used for controlled discharge of liquids from the tank container. They are available in different designs and connections and form an important part of the discharge system.

Spare Parts

In addition to complete valves, TK Guard also supplies various spare parts, including gaskets, seals, handles, fastening materials and other components for maintenance and repair.

Frequently Asked Questions

What is the difference between an ISO tank container and an offshore tank container?

An offshore tank container is specifically designed for use on offshore installations and must withstand higher mechanical loads and stricter safety requirements than a standard ISO tank container.

Which components wear out the fastest?

Components that are operated frequently, such as ball valves, airline valves, pressure relief valves, gaskets and seals, are generally the most sensitive to wear and require periodic replacement.

Are offshore components interchangeable?

This depends on the manufacturer, tank configuration and applied standard. Always check the specifications or contact TK Guard for technical advice.

Does TK Guard also supply individual spare parts?

Yes. In addition to complete valves and systems, we supply a wide range of spare parts for maintenance, repair and overhaul of offshore tank containers.
