As defined by the International Maritime Organization, an offshore container is a "portable unit specially designed for repeated use in the transport of goods or equipment between fixed and/or floating offshore installations and ships. Known in the offshore oil and gas community as "slippery rails "as they are often used to transport large assemblies to drilling and production rigs.
DNV's certification standards 2.7-1, 2 and 3 are a globally recognized set of certification standards for offshore containers and marine service modules. ​The certification standards relate to the certification of all types of marine containers as transport units. The three typical stages of transportation are: shore-based residency (eg, forklifts), supply vessels, and loading and unloading offshore facilities. The certification standards include design requirements related to all three phases.
There are five basic steps for DNV approval and certification:
1. Certification of our (or our client's designation) written welding procedures, laboratory tests and welder qualifications
2. Evaluate and approve our primary device/skid/frame designs
3. Audit/Survey during initial welding start-up
4. Production：Audits/investigations during equipment manufacturing
5. Prototype testing：For "type" approval (type approval means a series of identical units are manufactured over a period)

EMS (Energy Management System) is an important part of the container energy storage system. It is the "brain" of the energy storage container. It can realize the centralized management and intelligent operation of the energy storage system. It plays a decisive role in the safe operation, response characteristics and economic benefits of the energy storage container.
1. The basic information of the battery, BMS（Battery management system）， PCS（Power Conversion System）and working environment status information of the energy storage system and other basic data are obtained via Ethernet communication and processed and analyzed to intelligently manage, control, and dispatch the charging and discharging of the battery module.
2. With a visually interactive interface, it can update and display the status of the energy storage system in real time.
3. Record and store energy storage system state data, fault alarm data, staff operation information, etc. into the database for call and query during operation.
4. It can also perform online and real-time health status evaluation on the battery, which facilitates users to understand the battery's performance in a timely manner, improve work efficiency and reduce work burden.

IMO (international maritime organization) has adopted mandatory measures to reduce emissions of greenhouse gases from international shipping, under IMO's pollution prevention treaty (MARPOL) - the Energy Efficiency Design Index (EEDI) mandatory for new ships, and the Ship Energy Efficiency Management Plan (SEEMP).
MEPC 74 (May 2019) adopted on Invitation to Member States to encourage voluntary cooperation between the port and shipping sectors to contribute to reducing GHG emissions from ships. This could include regulatory, technical, operational and economic actions, such as the provision of: Onshore Power Supply (preferably from renewable sources); safe and efficient bunkering of alternative low-carbon and zero-carbon fuels; incentives promoting sustainable low-carbon and zero-carbon shipping; and support for the optimization of port calls including facilitation of just-in-time arrival of ships.
The Global Industry Alliance to support low carbon shipping (GIA), operating under the auspices of IMO’s GloMEEP project, has recognized the key role of ports in the decarbonization of shipping. In particular, just-in-time (JIT) operation of ships has a potential to reduce emissions. The GIA has been gathering experience from ports that have successfully (or unsuccessfully) implemented JIT; has been analysing barriers; and has been studying concrete measures for removal of these barriers to large-scale uptake of JIT.
Is zero-carbon shipping going to become a reality?
In the initial IMO strategy, there is a clear ambition to pursue efforts towards phasing out GHG emissions from international shipping entirely, by the end of this century. This has to become a reality.
As United Nations Secretary-General Antonio Guterres has said, “We need to put the brake on deadly greenhouse gas emissions and drive climate action…. The world is counting on all of us to rise to the challenge before it’s too late”. Research and development will be crucial, as the targets agreed in the IMO initial strategy will not be met using fossil fuels. There is a need to make zero-carbon ships more attractive and to direct investments towards innovative sustainable technologies and alternative fuels. 

1. During the test, a uniformly distributed load equivalent to the difference between the rated mass and the tare weight of the container should be placed in the container and fully bolted.
2. The ground on which the offshore container falls should be a flat concrete floor or other hard surface. The ground may be covered with planks, which shall not exceed 50 mm in thickness.
3. Lift the marine container tilted so that the angle between the side beam and the end beam connected to the lowest angle on the bottom of the container and the ground is not less than 5°. On the bottom surface of the container, the height difference between the lowest corner point and the highest corner point should not be greater than 400 mm.
4. During testing, the corner with the worst stiffness should be selected as the lowest impacted corner.
5. The lowest corner point of the offshore container should be more than 50 mm away from the ground. The initial impact velocity of the offshore container touching the ground shall not be less than 1m/s.
6. After testing, the offshore container shall not show significant permanent deformation or damage. Small repairable open welds and deformations are allowed.
TLS will not proceed to the next production step until the marine container has passed the vertical impact test

​The production process and requirements for TLS offshore container are as below:
1. Produce the container frame and weld the container.
All primary structural welds are required to be welded by a class-certified welder, and full penetration welding is required. For containers that have passed the third-party inspection, they are sprayed according to the paint process, and the paint package is suitable for the marine environment

2. Install the floor.
First, calcium silicate plates were laid on the lower deck, then fixed steel mesh was installed on the surface, then the upper deck dressings were laid on the steel mesh, and finally the deck dressings were laid on the floor. After construction is complete, the flatness of the floor is measured and accepted by professional quality inspectors.

3. Lay down insulation material.
Fix the nails in advance at the locations where the rock wool insulation needs to be laid in the container. When attaching the nails, reserve space to make sure that the nails are firmly attached according to the standard.  Laying of rock wool ensures that the length of the overlapping surface is sufficient, and the joints are covered with fireproof tape.

4. Install water pipes, air pipes, and cable trays.
Pre-lay insulation. Reserve the supporting boom needed to install the pipe on the top plate of the container to ensure that the pipe is straight and firmly secured.

5. Install interior trim wall panels.
Install the fixing slot of the fixing plate first, and then install the inner panel in the fixing slot. Before installation, ensure that the surface of the wall panel and the ceiling is smooth and flat, and ensure that the splicing gap is neat and straight.

6. Install the furniture and appliances. The furniture in the container must be installed and secured according to the requirements and locations in the preliminary design drawings. The power connection of the relevant equipment shall be constructed in accordance with the regulations and must be inspected by qualified quality inspectors during this period.
​
7. Testing & Acceptance
TLS accepts client's on-site inspection, video inspection, graphic inspection, and other methods for acceptance. We will only ship the containers after they pass the acceptance.

The basic principle of the negative pressure system is to keep the pressure of the environment inside the container lower than that outside, so that the toxic gas or flammable gas in the container will not be directly discharged from the it, and the negative pressure system captures dangerous and infectious particles in the air, and it is removed with a blower and a set of filters.
The negative pressurized container provide by TLS typically has 2 fans, a small fan for normal mode and a large fan for emergency mode. When either fan is turned on, a negative pressure environment is formed inside. When only the small fan in the fume hood is turned on, the internal pressure is around -30~40Pa, and normal ventilation mode in the container; When the flammable gas/H2S low level alarm is triggered, the outdoor Ex-fan will automatically turn on, the internal pressure is around -130Pa and the container enter the emergency mood and it will automatically turn off when the gas concentration is lower than the set value. If the gas concentration does not decrease, the high-level alarm of flammable gas/H2S would sound, after the alarm lasts for 10 seconds, the power supply of the container will be cut off.
Negative pressure is a safe sealing solution which is widely used in lab containers, Mud Labs, etc.

Why would you want TLS offshore workshop container instead of a garage or shed? There are a number of advantages that make it a better choice.

• Portability

Unlike the permanent structure you add to your property, offshore containers  are designed to be portable. They're easier to move from one place to another, and to remove from your property when you no longer need them. You can also quickly and easily have a fully equipped container workshop delivered to your location, and if you ever need to change location, you won't have to worry about leaving the workshop behind.

• Customization

Since an offshore container is basically just an open space, it's easy to design your workshop the way you want it. You can add shelving, benches, lighting and all your tools in exactly the arrangement you need.

• Durability

Although marine containers were originally designed for transporting goods abroad, their conversion into other useful spaces has become commonplace. Because shipping containers are made of high-quality steel, they are very durable and extremely weatherproof. They are therefore ideal for long-term use outside.

1. Offshore containers shall be tested according to the requirements of four-point lifting and two-point lifting respectively.
2. During the lifting test, the lifting angle should be the design angle.
3. The lifting process should be carried out smoothly to avoid obvious inertial load.
4. The deformation measurement of the beam and the integrity inspection of the offshore container should be carried out after keeping the lifting state for 5 minutes.

   
   FOUR-POINT LIFTING

1. When lifting, a uniform load equivalent to 2.5R-T should be placed in the box.
2. During the test, the deformation of the beam should not exceed 1/300 of the beam span. After the test, the container shall not show significant permanent deformation or damage.

   
​    TWO-POINT LIFTING (DIAGONAL LIFTING TEST)

1. Select two lifting lugs at diagonal positions for lifting. When lifting, a uniform load equivalent to 1.5R-T should be placed in the container.
2. If the container is not geometrically symmetrical, the lifting test shall be carried out on the two diagonal corners respectively.
3. After the test, the container shall show no obvious permanent deformation or damage.

 
R - maximum allowable total mass of offshore container and loaded cargo (without spreader)
T - Empty mass of offshore container including attachments (without spreader)
The TLS containers will not promote the next production step until the lifting test is passed.

With the gradual deepening of the development and utilization of oil and gas resources by human beings, oil and gas exploration and development have shifted from the shallow continental shelf to the deep sea, drilling engineering operations must also be carried out in the ocean away from the continental shelf.
In the event of a fire, explosion, leakage or other critical situation on the platform, the personnel on board can escape to the temporary refuge shelter, guarantee the life safety of the personnel in the temporary shelter within a certain period, and organize the person discuss the escape strategy, and gain time to be rescued.
Features of temporary refuge shelter provided by TLS:

1. The positive pressure system is designed to maintain a certain positive pressure in the temporary shelter compared to the outdoor atmosphere during emergency conditions, preventing toxic gases from outside the container from entering the temporary shelter.
2. The compressed air is stored in the air bottle in the shelter, which can maintain the breathing needs of all the people who escaped to the temporary shelter on the living platform within a certain period.
3. The structure complies with the DNV2.7-1 design, and the thermal insulation and fire protection standards of the shelter are A60 level, ensuring its fire-resistant integrity within 60 minutes.
4. The HVAC system should ensure that the heat on the enclose does not exceed the maximum human tolerance, can resist thermal stress, and can last for 60 minutes in an emergency.
5. The backup supply can ensure that the emergency power supply can activate the HVAC and lighting systems in the event of a mains power cut.
