Adaptive Engineering Services (AES) provides engineering services and products to the oil and gas industry, focusing on offshore systems and deep-water applications.

AES provides its customers with turnkey system solutions and expertise in design, engineering, testing, ABS and DNV certifications, procurement, construction, quality control, installation, maintenance and repair of offshore and subsea systems.

Offshore and marine systems

Through its applied technology and fabrication expertise, AES provides a wide range of integrated engineering services and turnkey offshore systems, including:

AES provides design, engineering and turnkey winch projects for offshore and subsea applications, which are carried out and built in accordance with ABS regulations.
A functional and structural joint, which is designed for a festooned subsea pipeline system. It is fabricated by induction bending process and reinforced to survive the installation and operational loads.
Adaptive Engineering Services (AES) supervised the design, engineering and testing of a piled receptacle foundation for the anchoring of a 9.5t steel pipe joint at 280msw depth.
AES performed the design, engineering and testing processes of a piled receptacle foundation for the anchoring of a 9.5t steel pipe joint by ROV-operable locking mechanism.
A 12-man 1,000fsw SAT Project with diving bell, transfer under pressure, decompression chamber, HRC design, engineering and ABS certification services from AES.
The 1,000fsw 12-man SAT System installed on the Swordfish offshore supply vehicle (OSV).
A full-scale prototype test set-up of a pipeline joint to validate the design solution under tension, bending, torsion and internal pressure loads.
The development and fabrication of an innovative HDPE100 flange with 1,850mm diameter and high-dimensional accuracy with tolerances of up to 0.5mm.
An optimised stub-end flange design to survive the external static and dynamic loads, which the flanged connection is exposed to underwater service.
AES performs deck reinforcement and SAT system mobilisation on XBOW Poseidon for DNV certification.
