On-Site Services

Bolt Torquing / Tensioning

In most Industries, precommissioning and maintenance schedules are placing an increased emphasis on 'flange management' from the design stage, with the objective of a 'leak free' start up. Alstern Technologies promote the benefits of 'controlled tightening' . . . being the use of specially designed equipment, proven bolt loading calculations and written procedures, to tighten joints to the desired tolerances in a controlled and safe manner.

The integration of flange management with our Nitrogen/Helium leak detection and other services can produce substantial reductions in manpower, interfaces to be managed, and lead to a more efficient and cost effective plant start-up.

On-site Machining

We provide on-site machining services such as In-line boring, facing, milling, drilling, etc. Anything which cannot be machined in a workshop can be efficiently machining on-site by having equipment and manpower brought on-site. With access to portable machines, we are continuously building up our range of specially designed equipment to carry out precision and heavy duty machining operations at any locations throughout the region.

Laser Alignment / Measurement

Laser alignment is used when connecting pipes to rotating equipment to ensure pipe stress is minimised. Laser alignment is also used to align rotating machinery to their required tolerance. Laser alignment system has higher resolution than conventional dial indicators and therefore provide a more accurate alignment result

Laser measurement on offshore platform between different modules provide a accurate and consistent measurement for tie-in points.

Alstern Technologies worked closely with the HSE to develop and advance techniques to significantly reduce the amount of airborne asbestos fibres during removal projects

Heat Shield

Al tern Technologies provides a complete design, project management supply and installation service for our heat shielding systems. Our heat shields are light-weight, rigidly structured without moving parts and they are able to withstand offshore environment and rough handling. Our heat shields are designed to protect personnel, equipment and flare deck away from potential explosion, high temperature/ radiant heat exposure and fire hazards.

Heat Trace

Alstern Technologies provides design, supply and installation of heat trace using electrical and steam. Our scope of service designing the appropriate heat or steam trace system and on-site installation service including mounting of transformers and control panels, running power and control cablings, installation of heating cables (tubings) and accessories and testing and commissioning.

Passive Fire Protection

Alstern Technologies provide protection of hydrocarbon and jet fire on bulkhead, vessels, pipes, cable tray system and structural members using cementitious-based or mastic based PFP products. These products are capable of withstanding 60 minutes jetfire (J30) and 60 minutes hydrocarbon pool fire (H30).
