IDS benefits

Removing critical welds

The structural integrity, strength and fatigue life of the IDS is significantly enhanced through design by replacing the traditional low pressure wellhead housing and the circular welds of the conventional high pressure wellhead.

Machined forgings, optimized material

The critical IDS structural components consist of optimized material grade forgings, specifically qualified for its design purpose.

Upper and lower section

The upper section consists of a traditional high pressure housing geometry, managing all triaxial stresses from vertical weights, bending loads and internal differential pressure. The upper section therefore can accept a high yield grade, is machined only and require no welding. The lower section replaces the traditional low pressure housing and is designed to manage axial and loads, with relative low exposure to differential pressure. Material with higher carbon level is selected to better optimize for welding and load transfer to the CAN. The upper and lower structural sections of IDS is connected by a compact flange.

Compact flange technology

The Compact Flange technology is a high strength static connection used for dynamic applications, historically used in riser systems and pipelines. The concave geometry of the flange will be forced together by the pre-tension of the bolts, causing the bolts never to see any dynamic loads.

Finite Element Analysis

The detailed geometry and stress concentration of the IDS has been optimized through Finite Element Analysis (FEA) conducted by IKM Tech Team. Optimized geometry has resulted in fatigue life of several years under with worst case load conditions.

DNV GL RP A203

The design and qualification process of the IDS has been closely followed by DNV GL, and the technology development process has been executed according to RP A203.
