Asian Offshore Services (AOS) is an internationally recognised designer and manufacturer of modular buildings and cabins for onshore and offshore oil and gas, petrochemical and marine applications. The modules are designed to be installed individually, coupled or stacked at site or pre-coupled and stacked to form a ‘single-lift’.

Our modular design concepts are suitable for onshore process plants, offshore oil and gas platforms and marine or drilling support vessels. AOS specialises in three specific types of modular designs that are suitable for either new build projects or refurbishment of existing plant and equipment as follows:

• E-house (electrical and instrument equipment rooms)
• Living quarters
• Multi-purpose

In support of our design and build services AOS also provide onshore or offshore site installation, hook-up and commissioning services of our modules.

Typical applications for offshore and onshore modular buildings and cabins

E-houses

• Electrical switchgear (MCC)
• DCS process control
• UPS and battery support systems
• Fire and gas
• Telecommunications
• Power generation system controls (turbines or recips.)
• Gas compression controls (turbines or recips.)

AOS E-houses can be designed in modular form that allows for pre-installation of electrical and instrument vendor equipment and factory testing prior to shipping to site in a controlled and clean environment. This dramatically reduces site hook up and commissioning time and provides major benefits particularly on fast-track projects.
