Offshore

Expertise in pipelines, risers / umbilicals and moorings has been gained through installation and operational engineering in the North Sea, Gulf of Mexico, West Africa and Brazil. This includes work at detailed levels (eg. pressure rating), component levels (eg. integrity) and trunkline levels (eg. feasibility / resourcing).

Zentech provides a comprehensive service for the design of structures (including topsides and heli-decks), and the analysis of pipe stress, flexible risers, steel pipelines, flowlines, pipeline routing, laying and prevention of upheaval buckling. We have designed and analysed process control systems and pipelines for the petro-chemical, oil and gas, nuclear, water and process industries.

Engineering projects have received approval from regulatory agencies, including DnV, ABS, Lloyd's, NPD and Rolls-Royce.

We are experienced in a range of services including:

• design and relocation of offshore platform jackets and decks
• conversions of semi-submersibles, jackups and other drilling rigs
• design of floating barges and minimum space drilling rigs
• fatigue, mooring, motion, collision and pushover analysis
• intact and damage stability analysis
• foundation engineering
• assessment of functional, operating and accidental loads
• detailed stress analysis
• weight control and centre of gravity analysis
• transportation, launch, upending.
