GE Oil & Gas has worked with Subsea Riser Products Ltd (SRP) to develop and create new completion and workover riser connectors for the offshore market. According to GE, these will save valuable rig time during operations.
Nimway completion and workover riser connectors
SRP, an Acteon company, was awarded a US$4 million contract to develop and qualify SRP’s Nimway 510 and Nimway 710 completion and workover riser connectors, which are designed for water depths of up to 3000 m.
GE Oil & Gas has obtained exclusive rights to SRP’s 5 ¼ in. and 7 ? in. 10000 psi connectors for two years – with the option to extend annually.
Nimway is a new design of high-capacity, quick-make-up connector. It has been developed using proven technologies and a novel tensioned sleeve design that has evolved from SRP’s experience in designing high-pressure dynamic flanges.
Connector’s system consists of metal sealing and dual bore capability, which are beneficial to their design.
Connectors qualification programme
At present, SRP is putting the new connectors through a qualification programme. This involves manufacturing the connectors, welding them to production-grade pipe and testing their endurance using hydrostatic pressure, bending and resonant fatigue tests. This qualification programme will be completed primarily in Houston, USA and expected to be complete by 1Q16.
Comment from GE Oil & Gas
Carl Roemmele, WellAccess Leader of GE Oil & Gas, said: “The Nimway connector work is a vital piece of the Subsea WellAccess portfolio that will differentiate GE’s offering in terms of code compliance, operational running speeds and costs. When we add it to the other WellAccess products we are developing, we will have a technically differentiated product line that shall be a compelling offer for our global customers.”
