About Us Andrew Woodward Andrew has a BEng and an MSc in Mechanical Engineeringfrom Aston University. Andrew has over 10 years experiencein Technical Sales and Estimation in Specialist Applicationsand joined the MORGRIP team in 2016. Andrew is now theMarket Manager for Subsea Products including MORGRIP atConnector Subsea Solutions. Chris Matthews Chris joined the MORGRIP team in 2014 shortly afterfinishing a BEng in Aerospace Systems Engineering atCoventry University. After short period working withstandard products Chris was engaged in a high profile projectfor Mechanical Connectors for Deep Water Repairs whichlasted 2 years. After that Chris was a leading figure on theengineering team developing the new MORGRIP CLiPConnectors which are the subject of today’s presentation.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. What are the limitations? Size, pressure, temperature and material?. A. The MORGRIP CLiP Connector design is designed andDNVGL Type Approved for 10” to 26” pipes in carbon steelwith a corrosion resistant alloy liner in maximum workingpressures up to 364bar, temperatures -40 to 149 degrees.These limits were set by the JIP partners based on theirrequirements. Applications outside of this range of size,temperature and pressure can be considered if required asthe base technology is adaptable and scalable.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Is it suitable for fatigue applications? A. Fatigue properties are in line with a good quality weldedconnection. Fatigue testing undertaken under an earlierDNVGL Type Approval for MORGRIP Connectors and wasaccepted by the JIP partners and DNVGL as applicable to thisconnector variant.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Is there any code to refer these connectors? A. The MORGRIP CLiP Connectors are DNVGL Type approvedto DNVGL-ST-F101 for Submarine Pipelines and DNVGL-RPF113 recommended practices for pipeline repair. Otherstandards can be considered if required.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Do you recommend to do stress analysis check on pipework where it is being used,in terms of sustained loads? A. We provide a design basis document detailing the grippingand sealing forces generated on the pipe by MORGRIP connector activation. Any additional stress analysis eg for theweight of a connector if deployed in a freespan condition is tobe undertaken by the operator or their appointed engineeringcontractor. We can provide relevant inputs such as weight ofthe connector to assist in these analyses as required.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Would you not have a galvanic corrosion issue with the graphite and a clad waterinjection pipeline?. A. The area of exposed graphite is extremely small, to nonexistent compared to the surrounding area of steel. This is alwaysregarded as the safe way to minimise galvanic corrosion byhaving a large ratio in area between the anode and cathode, sothat any galvanic corrosion is spread over a relatively large area.Where traditional MORGRIP connectors have been in service fora number of years and then recovered where a pipeline has beendecommissioned no evidence of galvanic corrosion was observed.The CLiP Connector is a development technology which has beentested but not deployed in the field to date.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Is this suitable for high torsional moments?. A. Yes the connector design is well suited to torsionalmoments. We request this type of load data to be providedduring an application check so we can design the connectoraccording to the project requirements.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Has there been any report of failure of connectors?. A. The MORGRIP CLiP connector is a developmenttechnology which has not entered service to date but hasbeen through a rigorous process of design qualificationincluding extensive testing. The design is based around thewell known MORGRIP Connector technology. In over 3000MORGRIP applications supplied to date there have been noin service failures.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Are the clamps classed as a permanent repair solution? If so would there have tobe specific considerations or inspection to the clamp itself for something like a FFP orpipeline life extension? A. The MORGRIP CLiP Connector is classed as a permanentrepair under the DNVGL Type Approval. Any inspectionrequirement would be applicable to accessories such asanodes which may be attached to the connector. Otherswisethe connector is treated in the same way as the rest of thepipeline with respect to inspections. CSS do have a separateclamp product line with both permanent and temporaryrepair clamps available.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. What are the maximum and minimum diameter for these solution? A. For this product currently 10” to 26” pipelines are coveredby the type approval however the technology is adaptableand scalable. For example the standard connector technologycovers ½” to 44” pipe diameters. Refer also answer 1.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Could be applied these repair option on accessories types Tee, elbows? A. Mechanical connectors can only be installed on a straightsection of pipe, the length of straight pipe required is clarifiedduring the bid/order process. Typically, even for a largeconnector, this length is below 2.5m. MORGRIP Connectorshave been used to enable the removal or installation offeatures such as tees and elbows in a pipeline system.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Was the new Clad & Lined pipe connector integrity tested in Fatigue? A. Fatigue testing undertaken under an earlier DNVGL TypeApproval was deemed to be suitable for this Connectorvariant was accepted by the JIP partners and DNVGL. Referalso answer 2.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. What lifetime do you anticipate for the connector? A. The MORGRIP connector life is as per the pipeline, a 30-50year design life is common.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. At what depth , you're able to execute such repairs? Is it feasible in deep seascenario , say 5000 metres & above? A. To date repairs in approximately 1300m water depth havebeen completed using CSS MORGRIP Connectors andinstallation tooling. The Connector technology can bedesigned to any theoretical depth by addressing theapplicable application pressures as required. CSS have uniqueexperience in repair of Deepwater pipelines and are availableto discuss any applications.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Is this suitable for pressure fluctuations and slug loads in two phase flow? A. Yes, the connector is suitable for multiphase flow andexplosive decompression. Any forces due to slug loads shouldbe provided for or assessment at application check phase inorder to be considered in the design.TOTAL Classification: Restricted DistributionTOTAL - All rights reserved

Questions and Answers – MCF / ICorr Joint EventAberdeen – July.2020 Q. Who can we contact for any further information? A. Any further queries or requests for information can bedirected to andrew.woodward@connectorsubsea.comTOTAL Classification: Restricted DistributionTOTAL - All rights reserved
