Meta description: Offshore living quarters work best when sleeping, sanitary, office and shared spaces are planned together. See how TLS accommodation modules can be configured and connected for offshore projects.

An offshore accommodation project is rarely just a request for beds. Personnel need places to sleep, wash, store belongings, work, meet and eat. A well-planned living quarter brings these functions together as a coordinated group of modules, with the layout, utilities, fire boundaries and access planned for the host vessel or platform.

TLS designs offshore accommodation modules for functions including sleeping cabins, offices, meeting rooms, mess rooms, galley facilities, sanitary units and workshops. Modules can be configured around the required layout, capacity, equipment and certification basis. [TLS multi-level accommodation overview]

Start with the way people will use the space

The first planning decision is how the crew will use the accommodation throughout a shift and between shifts. A sleeping cabin needs beds, storage, lighting and a comfortable indoor environment. A sanitary module has different priorities: privacy, durable finishes, hot water, drainage and access for cleaning and maintenance. An office or meeting module needs work surfaces, seating, power and communications. A mess or galley space has its own equipment and service requirements.

Separating these functions into suitable spaces can make the overall arrangement easier to use and maintain. It also helps project teams identify which rooms need to sit together, where shared circulation is needed, and which functions require dedicated utility connections. The right combination depends on personnel numbers, operating pattern and the footprint available on the vessel or platform.

Configure each module for its function

TLS accommodation modules can include single or bunk beds, lockers with hanging and shelving space, desks and chairs, en-suite shower rooms, hot-water systems and air conditioning with individual thermostat control. Depending on the project, modules may also include fire and gas detection, emergency lighting and other specified systems. The interior fit-out is selected to suit the intended occupancy and room purpose rather than applying one layout to every project. [TLS project portfolios]

Room planning needs to account for more than furniture count. Bed placement affects access and circulation. Storage needs to remain usable without blocking doors or equipment.

Bathrooms need coordinated water, waste and ventilation connections. Electrical outlets, lighting, alarms and communications need to match the host facility. Resolving these details together helps avoid a room that fits on a drawing but is awkward to use in service.

Design the layout as a connected living quarter

For larger accommodation requirements, individual modules can form a broader living-quarter arrangement. TLS describes modules that can be stacked or linked, with project options such as deck-mounting pads, twist-lock connections and linking kits. These arrangements require engineering for the specific installation: structural support, module connections, fire boundaries, escape routes and utility distribution all need to work across the combined layout.[TLS multi-level accommodation overview]

TLS's project portfolio includes offshore living quarters for 120 people and a drilling camp in New Zealand. These examples show how accommodation can be planned at different scales, from individual cabins to multi-module facilities. Each project still needs its own layout and interface review. [TLS project portfolios]

Coordinate comfort with offshore requirements

Habitability and offshore performance have to be considered together. HVAC, noise, lighting, sanitary facilities and internal finishes affect daily use. Structure, lifting, installation, corrosion exposure, fire protection and emergency access affect the module's suitability for its location. Utility connections for power, fresh water, drainage, communications, HVAC and alarm systems must also align with the host facility.

Applicable requirements depend on the project. TLS's published accommodation information references DNV 2.7-1, EN 12079, ABS and fire-protection requirements as project-dependent design or certification bases. A60 fire protection applies to specified boundaries and assemblies; it should be defined for the actual layout and not assumed to cover every module or configuration automatically.

A living quarter designed around the project

The practical advantage of modular accommodation is that sleeping, sanitary, office and shared spaces can be configured as a coordinated facility while retaining a transportable modular form.

TLS works from the intended use, occupancy, layout, host-facility interfaces and applicable project requirements to develop the accommodation arrangement, equipment scope and engineering documents.

FAQ

What functions can TLS offshore accommodation modules provide?

Depending on the project, they can provide sleeping cabins, offices, meeting rooms, mess rooms, galley facilities, sanitary spaces and workshops.

Can the modules be arranged for different occupancy levels?

Yes. TLS offers customized layouts and equipment for the required capacity. The final arrangement depends on available footprint, room functions, access and project requirements.

Can separate modules be linked or stacked?

Project-specific linked or stacked arrangements are possible. Structural support, connections, fire boundaries, escape routes and service distribution should be reviewed for the combined facility.

Which standards apply to an offshore accommodation project? 

The project may specify DNV 2.7-1, EN 12079, ABS and fire-protection requirements. The required standards and certification scope should be confirmed for the module design and installation.

What makes an accommodation layout practical?

It coordinates occupant numbers and daily routines with furniture, circulation, sanitary facilities, maintenance access, utilities and emergency arrangements.

An offshore accommodation module is more than a set of rooms inside a container. Its layout shapes how people rest between shifts, move through the space, use shared facilities and find a little privacy in a demanding environment. A good plan is not simply the one that fits the most beds. It is the one that supports the way the crew will live onboard.

That makes room arrangement an important part of the project from the start. Decisions about bedrooms, bathrooms, circulation and shared areas are connected: changing one can affect how the others work.

Rest depends on more than the bed

Offshore teams may work different shifts, so people in the same accommodation area may be resting at different times. A bedroom should provide enough space to get in and out comfortably, store personal belongings and use the furniture included in the design. The location of doors and circulation routes also matters, especially when people need to move around while others are sleeping.

Privacy is shaped by the overall plan as well as by the number of beds. A layout with separate rooms may offer more individual space, while shared rooms can accommodate more occupants within a given footprint. Neither arrangement suits every project. The balance depends on crew routines, the expected length of stay and the space available.

Shared facilities need a practical arrangement

Bathrooms and showers are among the spaces used repeatedly throughout the day. Their number and location affect how easily people can use them around shift changes, and they need to work with the module’s water, drainage and ventilation services.

The facilities also take up space that could otherwise be used for bedrooms, storage or a shared area. This is why a room plan should be considered as a whole. Adding a bathroom or increasing the number of sleeping places can affect circulation, privacy and the usable area in other rooms.

Circulation is part of the living space

Corridors, entrances and door swings are sometimes treated as leftover space on a drawing, but they are part of how people experience the accommodation. Narrow routes can make it harder to pass one another or carry personal items. Poorly placed doors can interrupt furniture layouts or reduce privacy.

The module’s internal partitions, fixtures and service routes also occupy space. A scaled floor plan helps reveal these interactions before the room arrangement is finalized. It makes it easier to compare options such as a different room mix, a longer module or a more compact shared area.

When connected modules make sense

If one module cannot provide a comfortable room arrangement, linked modules may create more usable space or allow sleeping and shared facilities to be separated. This can open up different layout possibilities, but it also introduces questions about movement between units and how the connection will be sealed and serviced.

The connection should therefore be considered alongside the floor plan. Structural interfaces, weather sealing, fire separation and electrical or plumbing services may need coordination, depending on the project design. Transport dimensions, lifting and the installation location can also influence whether a multi-module arrangement is practical.

A balanced layout starts with the way people will use it

There is no single room plan that works for every offshore project. Occupant capacity matters, but so do shift patterns, privacy, bathroom use, storage, available footprint and site constraints. Looking at these factors together helps teams understand the trade-offs between a higher bed count and a more comfortable day-to-day arrangement.

At TLS, accommodation layouts can be developed around the project’s intended use and constraints. Comparing layout concepts early can help the project team identify a practical direction before the detailed design is fixed.

FAQ

1.Does a higher bed count always make better use of a module?

Not necessarily. More beds can reduce available space for circulation, storage and privacy. The right balance depends on how the accommodation will be used.

2.Can bedrooms and bathrooms be arranged in one module?

 Often, but the workable combination depends on the module dimensions, room sizes, fixtures, doors and service connections. A floor plan helps show how those elements fit together.

3.What is the benefit of linking accommodation modules? 

Linked modules can provide additional floor area or separate sleeping rooms from shared facilities. Their suitability depends on the site, transport and installation conditions, as well as the design of the connections.

Accommodation designed around offshore routines

The most effective offshore accommodation layout considers how crew members move, rest and use shared facilities throughout their stay. By treating bedrooms, bathrooms, circulation and module connections as parts of one design, project teams can develop spaces that make better use of the available footprint.

Offshore accommodation modules are prefabricated units used to provide safe and practical living and working spaces for personnel on offshore platforms, vessels, drilling camps and other industrial sites. TLS can configure these modules as sleeping cabins, offices, meeting rooms, mess rooms, galley facilities, sanitary units and workshops.

The final module is designed around the number of occupants, required layout, equipment, fire protection, HVAC, offshore certification and connection requirements. TLS Offshore Accommodation Modules

What Types of Accommodation Modules Does TLS Provide?

TLS lists several types of accommodation and support modules, including:

• Sleeping cabins.
• Offshore offices.
• Meeting rooms.
• Mess rooms.
• Galley facilities.
• Sanitary units.
• Workshop spaces.
• Living quarters.
• Customized personnel modules.

Each type serves a different operational purpose. A sleeping cabin needs beds, lockers, lighting, HVAC and sanitary access. An office needs desks, chairs, power outlets, data connections and suitable lighting. A galley or mess room requires a different layout, furniture arrangement and service connection.

The module should therefore be designed according to its actual use rather than treated as a standard empty container.

How Many People Can an Accommodation Module Hold?

TLS publishes accommodation modules designed for one to eight people, with customized dimensions available for larger or different layouts.

The number of occupants affects:

• Bed arrangement.
• Locker space.
• Desk and workspace.
• HVAC demand.
• Emergency escape.
• Fire and gas systems.
• Sanitary facilities.
• Internal circulation.
• Electrical and communication requirements.

A customer should provide the required number of occupants and the expected use of the room before the design is finalized.

For example, a two-person sleeping cabin has different space and furniture requirements from an eight-person accommodation module or a shared offshore office.

What Is Included Inside a Sleeping Cabin?

Depending on the agreed specification, a TLS accommodation cabin can include:

• Single beds or bunk beds.
• Fire-resistant mattresses.
• Lockers.
• Shelves.
• Desks.
• Operator chairs.
• Reading lights.
• Electrical sockets.
• Data outlets.
• Air-conditioning.
• Shower rooms.
• Toilets.
• Hot-water systems.
• Smoke detection.
• Emergency lighting.

TLS also lists furniture and internal finishes designed for practical offshore use. The exact furniture arrangement can be customized according to the customer’s requirements and available space.

How Does TLS Address Offshore Safety?

Offshore modules may be exposed to marine weather, lifting operations, limited space and strict fire-safety requirements. TLS states that accommodation modules can be designed according to applicable project requirements such as DNV 2.7-1, EN 12079, ABS guidelines, SOLAS and fire-protection requirements.

Possible safety and protection features include:

• A60 fire-rated insulation.
• HVAC systems.
• Fire and gas detection.
• Alarm systems.
• Emergency lighting.
• Escape hatches.
• Fire extinguishers.
• Offshore lifting eyes.
• Certified lifting slings.
• Deck-mounting pads.
• Twist-lock connections.

The required features depend on the installation, certification and project specifications. A module should not be described as having a particular certification unless that certification is included in the agreed supply scope.

Can Modules Be Connected Together?

Yes. TLS lists twist locks, deck-mounting pads and linking kits for structural, mechanical and architectural connections.

This allows several modules to be arranged as a larger offshore accommodation or working area. For example, separate sleeping cabins, offices, sanitary units and mess facilities can be installed together as part of one modular arrangement.

The connection design should consider:

• Structural linking.
• Access between modules.
• HVAC connections.
• Electrical services.
• Fire and gas systems.
• Water and drainage.
• Emergency escape routes.
• Transport and lifting requirements.

The final arrangement should be checked as one connected facility rather than as a group of independent containers.

How Are Modules Transported and Installed?

TLS states that its modules can be designed for efficient transport, lifting and installation on fixed platforms and floating installations.

Possible provisions include:

• Certified lifting eyes.
• Certified lifting slings.
• Deck-mounting pads.
• Twist-lock connections.
• Linking kits.
• Quick connection to onboard services.

These features help simplify offshore mobilization. However, the customer should provide the lifting method, deck arrangement, transportation route and installation conditions before fabrication begins.
