Design and Engineering
As with most of our engineered products, we provide a Design data sheet in order to understand the particular project requirements, these are available on request from our sales department.
From the information provided by the client, our deisgn team can calculate the required Arch System dimensions, load ratings and weights. From this information Project Engineers are then able to co-ordinate the complex logistics required to source and fabricate all the components of the system.
The buoyancy element will be sized to provide the required 'upthrust to the risers', accounting for the weight in water of the Arch structure, mooring system, marine growth and buoyancy loss over the design life.
The shape of the Arch structure, the rating of the mooring system and the configuration and weight of the Anchor base are calculated in conjunction with the riser system dynamic analysis and therefore require close co-ordination and co-operation with the riser system designer.
The complete Arch Structure can be built to suit a design life of up to 30 years using special subsea coating and cathodic protection systems.
All design and engineering work conducted by us is in accordance with the latest international codes and specifications (e.g. DNV, API, ISO etc.)
