Container heat insulation and fire protection design refers to designing a set of heat insulation and fire protection system inside the container to protect the goods in the container from the influence of external temperature and fire. Commonly used insulation materials include rock wool, glass wool, polyurethane, etc., while fireproof materials include fireproof boards, fireproof coatings, etc.

TLS offshore containers can meet the A60 fire protection standard and usually use rock wool as an insulating material, which is made of basalt or lava mineral fibers. It has the following characteristics:
High temperature stability: rock wool can maintain stable insulation performance at high temperature, and can be used for thermal insulation of high temperature equipment.
Good thermal insulation performance: rock wool has low thermal conductivity and high thermal insulation performance, which can effectively reduce energy loss and reduce energy consumption.
Good fire performance: rock wool is a non-combustible material that will not burn or melt, and can effectively isolate the fire source and reduce the occurrence of fire.
Good sound absorption performance: The fiber structure of rock wool can effectively absorb sound waves, reduce noise transmission, and improve indoor comfort.
Environmental protection and health: rock wool products do not contain harmful substances, do not produce harmful gases, and are harmless to the environment and human health.

Using rock wool as a container insulation material can provide good thermal insulation performance, fire performance, sound insulation performance and environmental protection performance. When designing the insulation scheme, factors such as insulation requirements, cost and durability need to be considered comprehensively to determine the appropriate thickness and density of rock wool, and attention should be paid to the installation of rock wool and compliance with relevant fire protection and environmental protection standards.

In the heat insulation and fire protection design of containers, several aspects of design should also be considered:
Designing the insulation and how to insulate: The location of the insulation and how to insulate need to be determined. Generally speaking, the heat insulation layer can be designed on the inner wall, roof and ground of the container. At the same time, you can choose to use double-layer structure or single-layer structure for heat insulation.
Design fire protection layer and fire prevention method: need to determine the position and fire prevention method of fire protection layer. Generally speaking, the fireproof layer can be designed on the inner wall, roof and ground of the container. At the same time, you can choose to use fireproof boards, fireproof coatings and other materials for fire prevention.
Fire protection system design: The design of the fire protection system needs to be taken into account. This includes fire water sources, fire sprinklers, smoke detectors, etc.
Operator Safety: Operator safety needs to be considered. This includes things like lighting and ventilation systems inside the container.
​
Container heat insulation and fire protection design is a complex project, which needs to consider multiple aspects such as heat insulation, fire protection, fire protection system and operator safety. During the design process, it is necessary to comprehensively consider factors such as the nature of the cargo inside the container, the characteristics of the container itself, and the budget to determine the most suitable heat insulation and fire protection scheme.

Main structure:
Mainly divided into two categories
1. Important and non-redundant primary structures, which are the basic components that transfer the resultant load of the cargo to the crane hook or forklift (i.e. form the transfer path from the payload to the sling load), include at least: Top and bottom side beams, top and bottom end beams, corner posts, lifting lugs, fork grooves
2. Non-basic main structure. Examples include floors and other components with major functions other than those described for basic components. Baffles, stacking corners and end plates on hollow sections fall into this category. In addition non-essential primary structures also include protective framing members.

Secondary structure
The non-loaded parts that do not need to be considered in design calculations are called secondary structures, including
1. Door, wall and roof panels, non-slip cover
2. Reinforced plate and corrugated plate
3. Parts used only to protect tank structure
4. Internal fixed points

DNV stands for Det Norske Veritas, an independent and self-governing foundation dedicated to the protection of human life, the property and the environment both onshore and offshore. DNV Shipping Containers or Offshore Containers are certified containers for the oil and gas industry. This portable unit can be used many times, thus increasing its worth and viability.
 
When transporting large components to a drilling rig or FPSO (or storing products on site), you require containers that can endure harsh weather and movement. Due to certain hazards that may exist in the oil industry, DNV containers must comply with safety regulations in order to be certified for application on oil rigs, on oil tankers and in the environment.
 
DNV Shipping containers are divided into three main types:
Offshore freight containers：Suitable for carrying large loads and cargoes.

Due to the harsh environment at sea and the frequent lifting of offshore containers, there are strict requirements on the lifting lugs of offshore containers.

1. The design of lifting lugs should not exceed the limit formed by the outer surface of the frame, except the limit of the top.
2.  Lifting lugs are to be reasonably designed so that the slings connected to them are not entangled with containers or cargo.
3. The design of the lugs is to allow free movement of the shackles and slings without damaging the lugs.
4. In order to avoid lateral bending moment, in the hoisting state, the eye plate of the lifting lug should be coplanar with the vertical plane where the corresponding limb cable is located, and the maximum manufacturing tolerance is ±2.5.
5. When there are four lifting lugs, the relative positions between the lifting lugs should be arranged as a rectangle. The length difference between the two diagonals of the rectangle shall not exceed 0.2% of the nominal diagonal length or 5 mm, whichever is greater.
6. The design of lifting lugs should be matched with shackles, and one kind of lifting lugs should not be matched with shackles of various specifications. The clearance between the shackle pin and the lug hole should not exceed 6% of the diameter of the shackle pin.
7. The thickness of the lug hole shall not be less than 75% of the width of the shackle body.
8. If the lifting force is transmitted through the thickness direction (Z direction) of the plate, the plate used should have the corresponding mechanical properties in the Z direction. When plates with a thickness less than 15mm are used, an engineering justification for the material used shall be based on mechanical testing, ultrasonic testing, or review of chemical and mechanical properties.
9. Lifting lugs are to be connected to the frame by full penetration welding. It is recommended that the lifting lugs be connected to the main structural frame beams by inserting the lifting lugs into the slots of the main structural beams.

DET NORSKE VERITAS (DNV) is an autonomous and independent foundation whose goal is to protect life, property, and the environment at sea and on land. DNV undertakes classification, certification and other verification and consulting services related to the quality of ships, offshore equipment and facilities, and onshore industries worldwide, and conducts research related to these functions.
The DNV 2.7-1 certified offshore container is specifically designed for dynamic hoisting with eye pad devices and DNV certified slings fitted with shackles.
They are checked during the design phase, material procurement, production, and final loading and NDE testing. ​Not only are prototypes tested, but a specific number of units are randomly selected from each batch for testing at a rate five times the rate of ISO standard container testing.
The containers have a solid steel structure, including floors. They weigh almost twice as much as an ISO container of the same size, which is critical to their ability to maintain an upright position while being transported in rough seas. They must be equipped with DNV approved slings, stronger steel, stricter production specifications and have all the test documentation to prove their reliability in harsh offshore conditions.
 
Classification societies certify containers

• 1. Design evaluation: details of materials, cargo handling, container lifting and cargo tightening inside the cantainer.
• 2. Manufacturing process: certified inspectors authenticate and test raw materials to confirm that welder qualification, welding process and non-destructive carbon damage work meet the requirements
• 3. Test: Four-point lift, two-point lift, tilt test and drop test

Offshore containers should be inspected regularly every year. Regular inspections should be performed on the inside and outside of the container when it is empty. TLS has prepared tips for you to check including:

1. Inspection of signs and nameplates.
2.  Weld inspection of main structural members to confirm that there are no visible defects.
3.  Inspection of lifting lugs and lashing points for deformation, mechanical damage, or other dangerous defects.
4.  Inspect all structures for corrosion, deformation, mechanical damage, or other dangerous defects.
5. Check the condition of the container floor, including the bottom drainage facilities and drainage holes.
6.  Check for corrosion and mechanical damage inside the fork pockets (where applicable).
7. Check the door, frame, seal, hinge, door lock, etc., and confirm the opening and closing of the door.
