Strength and vibration analysis for machinery, equipment and components in industry
GL Engineering Services helps clients develop a safe and reliable mechanical component or technical system. The main service areas are concerned within the ship-, offshore- and industrial market. The principal assessment includes strength and vibration analyses for machinery, equipment and components.
Typical services are:
- Strength analyses in accordance with well-established rules and industry standards or equivalence analyses
- Fatigue analyses (classical and fracture mechanics)
- Vibration analyses (free and force-induced vibration analyses)
- Damage analyses
- Life time extension analyses

Strength- and vibration analyses of onshore- and offshore pipelines
To ensure the safe, reliable and environmentally friendly transportation of hazardous materials, it is essential to verify the pipeline design. GL acts as a third party for design verification. In order to be independent, most of the analyses are performed using in-house software. During pipeline life time GL performs flaw assessments, integrity management and evaluation of changed operating conditions.
GL offers:
- wall thickness determination (especially for deep water conditions)
- on-bottom stability
- free span analyses (static, vortex-induced vibrations, fatigue)
- local buckling
- global buckling (lateral- and upheaval buckling)
- riser analyses (static and fatigue)
- crossing analyses
- impact analyses (trawl gear interaction)
- laying analyses (normal, dynamic, abandonment & recovery , lifting, Tie-in)
- jumper analyses (static, VIV, fatigue)
- flaw assessment (ASME B31G, Kastner, BS 7910, etc. including crack growth analyses)
- pressure up-rating
- risk analyses for offshore & onshore pipelines (using GALIOM).

Consultancy concerning the use of sulphur reduced fuel
Effective from July, 1st 2010 the sulphur content of the fuel used is reduced to 1% in the zone of SECA/ECA (Sulphur / Emission Control Area). As a result, vessels upon entering an ECA must switch to low sulphur fuel operation in time if high sulphur fuel oil is used outside the ECA.
GL offers:
- Preparation of ship specific Fuel Change-over Manuals, which guides the crew during the changeover.
- Consulting services during adjustment of the fuel system to comply with low sulphur fuel requirement
