An intelligent pressurized container is an engineered enclosure that uses controlled ventilation, pressure monitoring, HVAC, electrical systems and safety controls to create a suitable internal environment in a hazardous offshore or industrial area. It is not simply a container with an air-conditioning unit. The pressure concept, hazardous-area classification, fire protection, gas detection, electrical equipment and certification scope must be developed together.

TLS designs pressurized containers for offshore, marine and hazardous-area applications, including Zone 1 and Zone 2 environments. Its published applications include mud logging cabins, MWD/LWD cabins, ROV control cabins, laboratories, workshops, accommodation cabins, control rooms, MCC shelters, switchgear shelters and generator enclosures. TLS Intelligent Pressurized Containers

What Does Pressurization Do?

Pressurization maintains the internal environment at a defined pressure relative to the surrounding atmosphere. Depending on the protection concept, this can help reduce the risk of hazardous external gas entering the enclosure and reaching personnel or equipment.

Pressurization does not remove every hazard. It must be supported by:

• Suitable clean-air supply.
• Pressure monitoring.
• Controlled doors and openings.
• Emergency response logic.
• Appropriate electrical equipment.
• Gas and fire detection.
• Defined shutdown actions.
• Inspection and commissioning.

A pressurized cabin should therefore be evaluated as a complete protection system rather than as a structural container with a positive-pressure fan.

How Is a TLS Cabin Configured?

TLS states that each pressurized container is configured around the operational, equipment and certification requirements of the project. Layouts and dimensions can be adapted for compact control cabins, process shelters and larger offshore modules.

The configuration may include:

• Integrated HVAC.
• Electrical power control.
• Pressurization systems.
• Data and communication networks.
• Fire and smoke detection.
• Flammable-gas detection.
• H₂S detection.
• Emergency shutdown.
• Fire dampers.
• Fire suppression.
• Ex-approved pressurization equipment.
• Airlock entrances.
• Emergency escape hatches.
• Battery-backed emergency lighting.

The final scope should distinguish between standard features, optional systems and customer-supplied equipment. A cabin described as “pressurized” does not automatically include every detection, suppression or control function.

How Are Fire and Gas Risks Addressed?

TLS lists fire and smoke detectors, flammable-gas detectors, H₂S detectors, emergency shutdown, automatic fire dampers and fire suppression among its available safety systems.

These systems perform different functions:

• Detection identifies a hazardous condition.
• Alarm communicates the condition.
• Shutdown isolates defined equipment or processes.
• Fire dampers limit the spread of fire or smoke through ventilation paths.
• Suppression controls a fire after activation conditions are met.
• Pressurization helps manage the movement of external atmosphere into the enclosure.

The cause-and-effect schedule should state what happens when each alarm is triggered. It should also define the response to loss of pressure, loss of ventilation, power failure, fire detection and gas detection.

What Standards and Certifications May Apply?

TLS states that its containers can be designed in accordance with project requirements involving DNV 2.7-1, EN 12079, IEC 60079-13, ATEX, IECEx, SOLAS, A0/A60 passive fire protection, ISO container standards and CSC requirements.

The applicable standard depends on the project. For example, offshore lifting and transportation requirements are not the same as hazardous-area electrical requirements. A fire rating does not replace a hazardous-area assessment, and a hazardous-area approval does not automatically establish offshore structural certification.

Third-party certification may be provided by organizations such as DNV, Bureau Veritas, Lloyd’s Register or CCS when required by the project.

The quotation should identify the exact certificate, design code, test scope and issuing body rather than simply listing several standards without defining applicability.

What Should Be Tested Before Delivery?

TLS lists factory acceptance testing and pre-commissioning for electrical and instrumentation systems among its pressurized-container capabilities.

The project should define the factory and site test responsibilities. Factory testing may include:

Electrical continuity and insulation tests.

• Instrumentation checks.
• Alarm and shutdown logic.
• Pressure-system checks.
• Fire and gas panel testing.
• HVAC operation.
• Emergency lighting.
• Equipment labeling and documentation.

Site commissioning should verify the completed installation, external connections, clean-air supply, pressure behavior, host alarms and emergency interfaces.

FAQ

1. Is a pressurized container suitable for every hazardous area?

No. Suitability depends on the area classification, protection concept, equipment certification, operating conditions and project approval requirements.

2. Does pressurization replace gas detection?

No. Pressurization and gas detection perform different functions. Detection identifies a hazardous condition; pressurization controls the intended enclosure environment.

3. What information should be provided to TLS?

Provide the area classification, intended application, equipment list, occupancy, layout, fire rating, certification requirements, utilities, lifting requirements and host-facility interfaces.

A BESS container is a modular energy storage system built inside a protected container. It can store electricity and release it when the project needs additional power. Depending on the project scope, a TLS BESS container can be supplied as an empty enclosure, a semi-integrated system or a fully integrated energy storage solution.

TLS configures each BESS container according to the required energy capacity, site conditions, cooling method, electrical system and level of integration. The solution is not limited to one fixed product design. TLS BESS Container Solutions

What Are the Main Types of TLS BESS Containers?

TLS offers three general levels of BESS integration.

The first option is a container enclosure. This provides the structural space for the customer’s battery racks, power conversion system and control equipment. It is suitable for customers who already have their own battery technology and system integrator.

The second option is a semi-integrated BESS container. It can include battery racks and selected auxiliary systems while leaving certain equipment or interfaces for the customer to complete.

The third option is a fully integrated BESS container. This can combine the battery system with cooling, protection and electrical integration. The final supply scope depends on the project specification.

These three options allow the customer to choose the right balance between project control, factory integration and installation speed.

What Energy Capacity Can a TLS BESS Container Provide?

TLS lists a BESS platform with an energy capacity range of approximately 3.73–6.26 MWh. The final usable capacity depends on the selected battery system, operating conditions, control strategy and project requirements.

The required capacity should be based on the purpose of the system. A project designed for peak-load shaving may need the battery to discharge during periods of high demand. A renewable-energy project may use the BESS to store electricity when generation is high and release it later. A grid-support project may require rapid response rather than long-duration discharge.

For this reason, customers should provide both the required power output and the required energy capacity. MWh describes how much energy the system can store, while MW describes how much power it can deliver at a given time.

How Does TLS Manage Battery Temperature?

Battery temperature affects system performance and service life. TLS lists both liquid-cooled and air-cooled BESS configurations.

The appropriate cooling method depends on the battery design, project location, operating temperature, heat generation and maintenance requirements. TLS’s published platform lists an operating range of approximately −30°C to +55°C, subject to the final configuration and project conditions.

The BESS design should include space for cooling equipment, electrical connections, maintenance access and monitoring. Cooling is not an independent accessory. It must work together with the battery racks, power equipment, control system and container layout.

What Protection Features Can Be Included?

A BESS container may require protection for the battery system, electrical equipment and surrounding site. The exact protection package depends on the battery technology, local regulations and project requirements.

The project specification may need to address:

• Battery monitoring.
• Electrical protection.
• Temperature monitoring.
• Cooling alarms.
• Fire detection.
• Emergency shutdown.
• External cable connections.
• Communication with the site control system.
• Maintenance and inspection access.

The customer should confirm which protection systems are included in the TLS supply and which systems will be provided by other parties.

What Can a BESS Container Be Used For?

TLS identifies several possible grid and energy applications, including:

• Energy shifting.
• Peak-load shaving.
• Power smoothing.
• Frequency response.
• Voltage support.
• Active power reserve.
• Custom power schedules.
• Renewable-energy integration.

The final operating function depends on the project’s control system and electrical design. A BESS container can support different applications, but the required battery capacity, PCS rating, control logic and grid connection will not be the same for every project.

FAQ

1. Does every TLS BESS container include batteries?

No. TLS offers different integration levels. Some projects may require only the container enclosure, while others may require battery racks and a complete integrated system.

2. Can TLS provide liquid-cooled BESS containers?

Yes. TLS lists both liquid-cooled and air-cooled configurations, depending on the project requirements.

3. Can a TLS BESS container support renewable energy?

Yes. BESS containers can be used for energy shifting and other applications related to renewable-energy integration, subject to the complete project design.

4.Is a BESS container the same as a backup generator?

No. A BESS stores electrical energy in batteries. A generator produces electricity using a generating set. The two systems can be used together when the electrical and control architecture is designed for that purpose.

An offshore reefer container is a refrigerated container designed to transport and store temperature-sensitive goods in offshore, marine and industrial environments. TLS reefer containers can be configured with refrigeration equipment, temperature control, fresh-air exchange, shelving and internal fittings suited to the cargo.

The purpose of the reefer is to maintain the required cargo environment during transport, storage and offshore operation. The final temperature range and equipment selection depend on the type of goods, operating location and project requirements. TLS Offshore Reefer Containers

What Can Be Stored in a TLS Reefer Container?

TLS identifies several types of temperature-sensitive cargo, including:

• Fruit and vegetables.
• Dairy products.
• Meat.
• Food supplies.
• Pharmaceutical or laboratory materials, when the required conditions are defined.
• Other temperature-sensitive goods.

The internal arrangement depends on the cargo. Some projects may need open floor space, while others may require adjustable shelving, storage racks or specific access arrangements.

The customer should explain the cargo type, packaging, loading method, storage duration and required temperature before the reefer configuration is selected.

How Does the Refrigeration System Work?

A reefer container uses a refrigeration unit to remove heat from the cargo space and maintain the required temperature.

TLS states that its reefer containers can be configured with refrigeration equipment from brands such as Daikin, Carrier or Thermo King, subject to project requirements.

The refrigeration system should be selected together with:

• Required temperature range.
• Cargo heat load.
• Outdoor temperature.
• Container size.
• Loading frequency.
• Power supply.
• Monitoring requirements.
• Alarm requirements.
• Fresh-air exchange.
• Humidity conditions.

The refrigeration unit must be suitable for the actual operating environment. A system selected only from the container size may not provide the required performance after warm cargo is loaded or doors are opened frequently.

Why Is Fresh-Air Exchange Important?

Fresh-air exchange helps manage the air inside the container. It can be important when warm or moisture-laden air enters during loading, or when stored goods release carbon dioxide.

Fresh-air exchange is especially relevant for fresh produce. Fruit and vegetables may continue to breathe after harvesting and can affect the internal atmosphere.

TLS lists fresh-air exchange, humidity control and air-delivery method as part of the reefer technical specification. These functions should be agreed with the cargo requirements instead of treated as identical for every reefer container.

What Internal Features Can Be Added?

TLS reefer containers can include features such as:

• Adjustable shelving.
• Door curtains.
• Forklift pockets.
• Customized internal layouts.
• Temperature monitoring.
• Alarm options.
• Selected refrigeration equipment.
• Cargo-specific fittings.

The internal layout should allow the cargo to be loaded, unloaded and inspected without blocking air circulation.

Shelving may be useful for smaller packages, boxed goods or supplies that need organized access. Open floor space may be more suitable for pallets or larger cargo. The customer should define the loading equipment and handling method at the design stage.

Can TLS Reefer Containers Be Used Offshore?

Yes. TLS lists offshore reefer containers designed for safe handling and efficient deployment in marine and offshore environments.

Depending on the project, the container may be designed in accordance with requirements such as:

• DNV 2.7-1.
• EN 12079.
• CSC requirements.
• Certified lifting arrangements.
• Forklift handling.
• Offshore transport and deck installation requirements.

The required certification depends on how the container will be transported, lifted and installed. A standard onshore reefer should not automatically be assumed to be suitable for offshore lifting or marine deployment.

What Should Be Monitored During Operation?

The reefer specification may include temperature monitoring and alarms. These functions can help operators identify conditions such as:

• Temperature outside the permitted range.
• Refrigeration failure.
• Loss of power.
• Door-open events.
• Abnormal temperature recovery.
• High or low internal temperature.

The monitoring system should be connected to the operating procedure. An alarm is useful only when the responsible person knows what action to take, such as checking the power supply, reducing door openings or transferring the cargo.

What Information Should Customers Provide?

To prepare a reefer proposal, customers should provide:

• Cargo type.
• Required temperature.
• Required humidity, if applicable.
• Cargo quantity.
• Packaging method.
• Loading and unloading method.
• Storage duration.
• Internal layout requirements.
• Power supply.
• Monitoring and alarm requirements.
• Delivery location.
• Offshore certification requirements.

This information allows TLS to select the refrigeration equipment, internal fittings and structural configuration more accurately.
