Maritime BESS containerised solutions for both retrofit and newbuilt vessels

11/30/2022

 
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.

​What is a maritime BESS containerized solution?
Containerized energy storage solution is a complete, self-contained battery solution for a large-scale marine energy storage. The batteries and all control, interface, and auxiliary equipment are delivered in a single standard shipping container for simple installation on board any vessel.

The standard maritime BESS container delivery includes
  • Batteries
  • Power converters
  • Transformer
  • Energy storage control system
  • liquid cooling & ventilation
  • Fire detection
 
How does maritime BESS container work?
The maritime BESS stores energy when demand is low, and delivers it back when demand increases, enhancing the performance of the vessel’s power plant. The flow of energy is controlled by dynamic Energy Storage Control System. It enables several new modes of power plant operation which improve responsiveness, reliability, safety, and fuel consumption.
 
What are the benefits of maritime BESS container?

Offshore Container Vertical Impact Test

11/29/2022

 
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

Do you know how to produce a high-quality offshore container?

11/23/2022

 
​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.

How the negative pressure container ventilation system works?

11/23/2022

 
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.

What are the benefits of an offshore workshop container?

11/21/2022

 
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.

  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.

What can Temporary Refuge (TR) Shelter work for?

11/14/2022

 
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.

What‘s the Function of BMS?

11/11/2022

 
BMS (Battery Management System) is one of the core subsystems of battery energy storage systems. It is a system that uses energy storage as a carrier to manage the storage of electric energy and the supply of electric energy over a certain period. The electric energy managed by BMS has functions such as smooth transition of electric energy, peak shaving and valley filling, frequency regulation and voltage regulation. It is also a device that monitors the status of energy storage batteries, intelligently manages, and maintains each battery unit, prevents over-charging and over-discharging of batteries, prolongs battery life and monitors battery status.
Its principal works are:
  • Battery status monitoring: Single battery voltage, battery pole temperature, battery loop current, battery pack terminal voltage, battery system insulation resistance, etc.
  • Battery state analysis: State of charge, power state, aging state.
  • Battery safety protection: overcurrent protection, overcharge protection, overtemperature protection
  • Energy control management: charge control, discharge control, balance control
  • Battery information management: battery information display, battery history information storage, information interaction within and outside the system
BMS works with PCS(Power Conversion System), EMS(Energy Management System), special air conditioning and fire protection systems to form the link control for each subsystem in the entire energy storage power station, ensure safe, reliable, and efficient grid-connected operation of mobile energy storage systems.

What's the necessity of Sewage treatment plant (STP) container?

11/10/2022

 
Why is sewage treatment necessary? Sewage is divided into domestic and industrial wastewater, which pollutes water resources so seriously that it has begun to affect people's normal lives. A variety of industrial wastewater and domestic wastewater discharged in large quantities, has polluted many water resources, making our lives available clean resources of water is increasingly lacking.
 
The harm caused by sewage is still expanding. The only way to better mitigate this vicious cycle of sewage pollution is to make more rational use of limited resources through industrial wastewater treatment. The treatment of wastewater discharged from our industrial production with sewage treatment equipment can make the completion of the purification of sewage to get the opportunity to use again, and also play a good role in protecting the environment, because some chemical plants excluded from the sewage has a lot of corrosive substances in it, if not industrial sewage treatment is discharged, it will cause great harm and pollution to the living environment, so that the conduct of Industrial sewage treatment work becomes very necessary.
 
TLS intelligent containerized wastewater treatment system or sewage treatment plant (STP) is a modular system where all wastewater treatment equipment is completely preinstalled in ISO standard or offshore standard containers. Our containerized sewage treatment plant (STP) is made for easy setup and relocation. This solution is ideal for remote locations such as mining camps and oil rig sites.
