It is a converted ULCC tanker with a SOFEC external turret mooring system, two flexible risers connected in a lazy-S configuration between the turret and a pipeline end manifold (PLEM) on the seabed, and an offloading system that allows up to two tankers at a time to moor and load, in tandem or side by side.
The name Flexcom derives from its origins as a computational software initially geared towards the analysis of flexible risers, befitting the emerging riser technology of the North Sea in the early 1980s. Although originally a time domain analysis tool, most versions of Flexcom also incorporate frequency domain analysis capabilities
The flexible hose riser may be in one of three basic configurations, all designed to accommodate tidal depth variation and lateral displacement due to mooring loads. In all cases the hose curvature changes to accommodate lateral and vertical movement of the buoy, and the hoses are supported at near neutral buoyancy by floats along the length.
The company produces dynamic and static risers, static flowlines, subsea and topside jumpers, and expansion joints for use in the offshore oil and gas industry. The NKT flexible pipe is an unbonded structure consisting of helically wound metallic armour wires or tapes combined with concentric layers of polymers, textiles, fabric strips and ...
This version was released in the mid-1980s under the name SESAM'80 and is the basis for today's Sesam. During the 1990s Sesam was further enhanced with a high-level concept modelling technique together with a design-oriented and unified user interface. Analysis features for mooring systems and flexible risers were also added.
A steel catenary riser (SCR) is a common method of connecting a subsea pipeline to a deepwater floating or fixed oil production platform. SCRs are used to transfer fluids like oil, gas, injection water, etc. between the platforms and the pipelines.
