Meta description: A pressurised PDU container provides a dedicated enclosure for power distribution equipment in projects that need a controlled workspace. Its layout is planned around the equipment, cable access and the way the container will be used.
What is a pressurised PDU container?
A PDU distributes electricity to connected equipment. When the equipment is installed in a hazardous offshore or industrial area, the project may require it to be housed in a pressurised container. The container creates a protected space for the specified equipment and is designed to suit the project’s operating conditions.
TLS has supplied pressurised PDU containers as a distinct product type. They are separate units, just as a pressurised work cabin and a pressurised office shop are separate units. Each has its own purpose and layout; they are not three functions combined in one container. ([TLS pressurised container solutions]
The equipment determines the layout
Power distribution equipment needs room for installation, operation and routine checks. The position of the panels, the direction from which people access them, and where cables enter the container all affect the layout.
These details are easier to plan before the container is built. Early coordination helps the equipment fit the space and keeps access routes clear. It also gives the project team a chance to agree where the container connects with equipment and services outside it.
Pressurisation is part of the overall design
In simple terms, a pressurised container supplies air to keep its internal pressure above the surrounding atmosphere. This can help limit outside air entering the enclosure, when the system is designed and operated for the project’s conditions.
The container, the power equipment and the pressurisation arrangement need to work together. The protection required depends on the site and project specification, so the same setup should not be assumed for every PDU container. TLS configures pressurised containers to the project requirements, with applicable standards and certification confirmed for each unit. ([TLS pressurised container solutions]
A purpose-built container for a clear role
A pressurised PDU container gives power distribution equipment a dedicated place within the project. When the equipment arrangement, cable access and protection requirements are considered together, the container is easier to install and use as intended.
For TLS, a PDU container is one specific configuration in a broader range of pressurised units. The final arrangement follows the equipment and project requirements, while work cabins, PDU containers and office shops remain distinct products designed for different uses.
FAQ
What does PDU mean?
PDU means power distribution unit. It distributes electricity to connected equipment.
Does every project need the same pressurisation arrangement?
No. The required arrangement depends on the project and its operating environment.
Can the container layout be planned around the equipment?
Yes. Equipment positions, cable access and normal operating needs can be considered during project design.
Meta description: Offshore functional containers are designed around the equipment they will house. Learn how enclosure layout, mounting provisions, openings, interfaces and offshore requirements come together in a project-specific container.
Direct answer
An offshore functional container is more than a standard box with equipment added later. Its dimensions, internal arrangement, structural provisions and service interfaces need to reflect the equipment it will house and the way the unit will be transported, installed and used. TLS designs and manufactures the container enclosure, coordinating agreed equipment positions and interface provisions with the customer’s requirements. The customer or its appointed vendors supply and integrate the process equipment and systems.
Start with the equipment’s role in the project
Offshore containers can serve very different purposes: a laboratory, workshop, control room, generator space or equipment room. The label alone does not determine the design. What matters is the equipment to be installed, the space people need to work around it, and how the container connects with the wider project.
For example, a laboratory container may need prepared locations for benches and customer-supplied instruments. A workshop may need clear working and access areas around machinery. An equipment room may require planned cable entries and mounting provisions. Each use leads to a different enclosure arrangement, even when the external container format is similar.
TLS’s offshore functional-container range includes laboratory, workshop, crane-support, generator, ROV/control and equipment containers. The company describes project-specific layouts, equipment loads, operating environments and certification needs as design inputs. ([TLS Offshore Workshop, Laboratory and Equipment Containers]
Make the container fit the equipment and its interfaces
The equipment list affects more than the floor plan. Weight and centre of gravity, footprint, access for maintenance, cable routes, openings and connection points can all influence the container design. Identifying these requirements early helps coordinate the enclosure with the equipment supplier’s installation needs.
This coordination can include equipment locations, mounting arrangements, cable or pipe entries, space for customer-specified systems, and access for operation or servicing. The exact provisions depend on the project drawings and agreed supply boundary. A reserved opening or interface should not be mistaken for the equipment or system itself being included.
TLS supplies the container enclosure and the provisions defined for that container scope. Process equipment, laboratory instruments, workshop tools, generator packages, control systems and other customer equipment are supplied by the customer or its appointed vendors unless a different scope is expressly agreed. Clear interface drawings help each party understand what is prepared in the enclosure and what must be installed by others.
Design for offshore handling and the final location
An offshore functional container needs to suit its transport and installation route as well as its permanent duty. Lifting and handling requirements, equipment loads, environmental exposure and the final site arrangement all need to be considered together. Internal equipment positions can affect structural loading and handling, so late changes to the equipment arrangement may require the container design to be reviewed.
The applicable offshore-container and project requirements should be established for the specific unit. TLS lists DNV 2.7-1, NORSOK, ATEX/IECEx and SOLAS/IMO among requirements that may apply to its functional containers, depending on the project. The relevant standards and certification scope must be confirmed for the intended installation; a list of possible standards is not a claim that every container carries every certification. ([TLS functional-container information]
Why early coordination reduces site complications
When equipment positions, access, openings and connection points are coordinated before fabrication, the container is more likely to arrive ready for the customer’s installation work. It can reduce avoidable changes such as relocating an entry, adjusting a mounting point or resolving a clash between equipment and an access route after delivery.
This does not remove the need for the customer’s equipment vendors to complete their own installation and system checks. It gives the project a defined physical interface between the enclosure and the systems that will be installed inside it. The container drawings, equipment data and responsibility matrix should describe that interface clearly.
A container engineered around its project role
The value of an offshore functional container lies in how well the enclosure supports its intended role. A project-specific layout, suitable structural provisions and well-coordinated interfaces give customer equipment a defined place within a transportable offshore structure. TLS focuses on engineering and manufacturing that enclosure to the agreed project requirements, while the customer and its vendors provide the equipment and systems that make it operational.
FAQ
What is an offshore functional container?
It is an offshore container designed for a defined use such as laboratory work, workshop activities, control, power generation or equipment housing.
Does TLS supply the equipment installed inside the container?
TLS supplies the container enclosure and agreed provisions. The customer or its appointed vendors supply the process equipment and systems unless the contract defines another scope.
Can the enclosure be designed around customer equipment?
Yes. Equipment dimensions, weights, locations, access needs and connection requirements can inform the container design and interface provisions.
Which standards apply?
Requirements such as DNV 2.7-1, NORSOK, ATEX/IECEx or SOLAS/IMO may be specified depending on the project and intended installation. Applicability and certification scope are confirmed for each unit.
Why define interface points before fabrication?
Early coordination helps align equipment positions, access, openings and connections with the enclosure, reducing the chance of avoidable modifications after delivery.
Meta description: A smart mud logging cabin is planned around the work performed inside it: operator positions, logging equipment, data interfaces, environmental control and the site's safety requirements.
Direct answer
A smart mud logging cabin works best when its layout and supporting systems follow the drilling team's workflow. Operator stations, logging equipment, data connections, cooling, ventilation and safety systems need to be coordinated as one working environment. Smart features such as edge-computing interfaces, environmental sensing and remote-communication provisions can be added where the project calls for them; they are configuration choices, not assumptions that apply to every cabin.
A drilling workspace, not just a room for instruments
Mud logging teams monitor and interpret information while drilling is in progress. The cabin must support sustained work by people while accommodating the equipment and connections used for that operation. That makes the relationship between operator positions, display sightlines, equipment racks and cable routes central to the layout.
For example, placing a rack close to a workstation may shorten connections, but it still needs enough access for inspection and service. A display arrangement should suit the team's normal lines of sight without obstructing circulation. Doors, emergency equipment and service panels also need to remain accessible when the cabin is occupied. These decisions are easier to resolve when the layout is developed around the work sequence rather than a generic furniture plan.
TLS develops mud logging and MWD/LWD cabin layouts around the intended operation and project equipment. The scope can range from a purpose-built enclosure with defined mounting and connection provisions to a more integrated package, depending on the agreed project supply. [TLS Smart Logging Container]
Coordinate equipment, data and services
Modern logging work involves more than the equipment footprint. The cabin may need mounting positions, cable paths, power distribution, UPS interfaces, data connections and communications provisions. Cooling and ventilation must also account for the people and equipment inside the enclosure.
When a project is intended to support local data processing, the cabin can be prepared with suitable interfaces for industrial computing or edge-analysis equipment. Remote communication ports and environmental sensors may also be specified. These options can help the enclosure support future upgrades, but a prepared interface does not by itself mean that data-acquisition instruments, analysis software or remote-control functions are included. Those items depend on the project scope.
Match environmental protection to the site
Drilling locations vary in temperature, humidity, dust, salt exposure and hazardous-area classification. The cabin's HVAC, filtration, corrosion protection and pressurisation arrangement should be selected for the actual site and equipment duty.
Where the site requires hazardous-area protection, pressurisation and its monitoring and safety responses must be designed for the specified classification and project requirements. Pressurisation is not a universal feature of every mud logging cabin. For offshore deployment, container structural requirements such as DNV 2.7-1 or EN 12079 address the offshore container basis; IEC 60079-13 addresses protection of rooms by pressurisation or artificial ventilation. The applicable standards, certification scope and installed systems must be confirmed for the specific project. [TLS pressurised-container capabilities], [IEC 60079-13]
Make smart upgrades useful and project-specific
Smart functionality has value when it supports a defined operating need. Edge-computing provisions can support local processing; environmental sensing can help monitor cabin conditions; communication interfaces can support remote data exchange. TLS describes these as optional or project-configurable capabilities. Full remote operation should not be implied unless it is specifically engineered and included in the supply.
The same principle applies to safety functions. Fire and gas detection, intelligent ventilation, emergency shutdown and other systems have to correspond to the cabin's location, equipment and approved safety design. A feature list alone does not explain how the systems interact; the project design defines those interfaces and responses.
The result: a cabin that supports the people and the data
A smart mud logging cabin is defined by how well its interior and supporting services enable the drilling team to work. When operator layout, equipment access, data routes, environmental control and site protection are designed together, the cabin becomes a dependable platform for logging operations and future system integration.
FAQ
What makes a mud logging cabin “smart”?
It can be prepared for project-specific data processing, environmental sensing, intelligent ventilation or communications. The exact functions depend on the selected configuration.
Does a smart mud logging cabin automatically include logging instruments and software?
No. The cabin, supporting systems and logging equipment can have different supply boundaries. Instruments, software and integrated systems are included only when defined in the project scope.
Can TLS customize the cabin layout?
Yes. The layout and service interfaces can be developed around the intended drilling workflow, personnel positions and equipment arrangement.
Does every mud logging cabin require pressurisation?
No. Pressurisation is selected when the installation environment and project protection basis require it. It should not be assumed from the term “mud logging cabin” alone.
Which standards may apply?
Depending on the installation, the project may specify offshore-container requirements such as DNV 2.7-1 or EN 12079, and hazardous-area protection requirements such as IEC 60079-13. The final standards and certification scope are project-specific.
Planning a mud logging cabin?
TLS can develop the enclosure, layout and supporting-system configuration around the drilling operation, site environment and agreed equipment interfaces.
