MORGRIP Subsea Connectors enable subsea pipelines to be joined or terminated in a flange or end cap, without the need for hyperbaric welding or hot work.

With a choice of gripping and sealing technologies available, we are able to meet a wide criteria of customer needs that balance the specific application requirements with quality, cost and delivery schedule options.

For DNV-GL Type Approved Subsea Connectors, the MORGRIP is supplied with our unique gripping and graphite sealing technology to ensure a connection that is at least as strong as the pipe itself, outperforming quality welds in fatigue loading.

With over 3000 supplied since the 1980’s MORGRIP retains a 100% in-service leak free record. These products are quick and easy to install significantly reducing shutdown windows and associated operational costs.

Technical Details:

The MORGRIP Connector is designed in full compliance with the pressure / capacity requirements of DNV GL-RP-F113 and ST-F101 where applicable.

For design purposes alternative codes, such as API-5L and  ASME B31.3, can also be used to determine the required test pressure.

All pressure retaining components can be designed in compliance with ASME BPVC VIII Div. 2 on request.

Features and Benefits:

  • Graphite seals offers a high pressure, high temperature option with excellent chemcial resistivity and indefinite shelf life ideal for long term storage.
  • Elastomeric seals require a lower activation load offering a more compact connector solution ideal for thin walled pipes
  • External pressure test facilities ensure joint integrity prior to commissioning
  • Full DNV, Lloyds and ABS accredited approvals exist for either permanent or temporary repair.
  • Can be used for emergency repair, planned shut downs and tie-ins, or stored as contingency equipment as part of an Emergency Pipeline Repair System (EPRS) club
  • Offering a 30 year design life; and providing a totally maintenance free solution
  • Can be provided on a project-by-project basis by our dedicated engineering team
