Our AptaraTM TOTEX-lite subsea system is easier and more economic to install, it operates smoothly, and is flexible enough to evolve for our customers over the life of field. This system has been born from our life-of-field approach to design, which aims to give subsea operators more flexibility around decisions about late-life infrastructure, and the lowest Total Cost of Ownership, therefore becoming a TOTEX-lite system.
Aptara™ Lightweight Compact Tree
The Aptara™ Lightweight Compact Tree system adapts as your needs change through the entire life of your field, with a plug and play capability in the cap without the need to introduce additional subsea equipment like subsea boosting. It has a significantly reduced footprint compared with traditional deepwater subsea trees, which means 50% less weight and the potential to reduce TOTEX (CAPEX + OPEX) by more than 50%. The Aptara™ tree allows you to evolve your tree system to suit changing reservoir conditions. Its unique patented industry-first design involves an innovative flow path and ‘caps’ for the tree that integrate functionality such as High Integrity Pipeline Protection (HIPPS) or add boosting capability to reduce your overall development cost or increase reservoir recovery.
The life-of-field cap also facilitates conversion of subsea wells from producer to water injection, adapting your subsea infrastructure to meet your reservoir management needs.

Aptara™ Modular Compact Manifold
Aptara™ modular compact manifold system has been developed to address the need for modular, pre-engineered manifolds that use off-the-shelf components, reducing cycle time cost and footprint. The new compact manifold from BHGE has been designed to challenge complexity with simplicity.
The Aptara™ manifold design uses a 4-slot or 6-slot dual header configuration to suit your pipeline requirements and 5-inch or 7-inch branch valve blocks for its branch valve connections, with separate header piping. The manifold branch valves are identical to our Aptara lightweight compact tree system valves (e.g. 5-inch trees require 5-inch manifold branch valves), pushing the boundaries of standardization to the next level. This enables large volume purchase of components like valves and forgings, allowing us to hold the stock you need – reducing cost and lead time.
Aptara™ Modular Compact Pump (MCP)
Aptara™ MCP is part of the TOTEX-lite family of subsea solutions and can unlock and enable access to your assets, even under the most challenging conditions, such as long tie-backs, low-pressure reservoirs or wells with difficult flow assurance. It provides a cost-effective and efficient solution, and unlike conventional subsea multi-phase pumps, which use a high-speed motor to drive a long shaft connected to a series of impellers, the MCP has a unique architecture with integrated motor impellers that rotate around a static shaft. This eliminates potential rotodynamic issues, whereas in a conventional pump, the motor is connected to the same shaft that drives the impellers, which limits the number of stages that can be stacked.
Our life-of-field approach to design is evident in the Aptara™ MCP’s unique features that reduce total cost of ownership.

Aptara™ Composite Flexibles
This new product is a hybrid of traditional flexible pipe designs, introducing 21st century materials technology for one specific layer – bringing 30% weight savings without affecting bending radius or compressive load capability.
For risers, this is achieved by reducing hang-off weights and platform burdens, simplifying riser configurations, and minimizing ancillaries and subsea infrastructure while keeping the exposure to new technology to a minimum.
The product eliminates riser system complexity, reduces cost and installation time while delivering predictable and stable hydrodynamic performance over the full product life cycle.
For flowlines and jumpers, we retain the flexibility this product brings with regards to final layouts, accommodating re-spuds and early deployment/wet storing of pipe to accommodate installation windows of opportunity, which may occur off the project critical path.
Particularly for high-sour or high-CO2 developments, this hybrid composite pipe significantly reduces permeated gas flow rate through the pipe annulus, reducing operational risk and adding cost benefits over the field lifecycle.
These flexible pipes are re-usable and can be redeployed to different duties and locations.
Aptara™ SFX Wellhead Solution
The SFX wellhead solution, part of the Aptara™ suite of TOTEX lite products, takes the field-proven architecture of our MS-700 and MS-800 subsea wellheads to the next level — delivering up to 16 times fatigue resistance improvement over existing systems. It also offers reduced cycle times, and extended drilling days in harsh environments.

Aptara™ Subsea Connection Systems
FLX360 is an innovative Multi-Quick Connect (MQC) system that enables fast and reliable connections between all elements of the subsea distribution system. The HCCS-L, also part of the APTARA suite, is a lightweight horizontal clamp connector suitable for rigid and flexible jumpers and spools, as well as, umbilical termination with multi-bore hub technology.
The FLX360 Multi-Quick Connection (MQC) System enables fast and reliable connections between all elements of the subsea distribution system. It uses a patented locking mechanism that leaves only one moving part of the design on the seabed. The complexity of the connection system is housed within the retrievable and serviceable ROV tooling, eliminating screw threads from the system and enabling reliable make up/ break out times of approximately 90 seconds. Its unique life-of-field design also allows maintenance in situ with no need for disconnection of the connector thereby reducing total cost of ownership.
The HCCS-L Lightweight Horizontal Clamp Connection System is a proven horizontal connector suitable for rigid, and flexible jumpers and spools, as well as umbilical termination with use of multi-bore hub technology. The HCCS-L range has been designed to be lighter, smaller and optimized to minimize make-up time, allowing for rapid installation. They come with a pre-mounted stroking tool and require fewer subsea operations, reducing the connection time by more than 30%. Our unique push-type stroking functionality allows full access for cleaning and cap replacement with the pre-mounted stroking tool.
