North SeaNorth Sea• Rising concern for pipeline damage in the late

1980’s

• Pipeline owners agreed on a Pipeline Repair System (PRS) Pool

A l t l l f i t ll f t i f• A large tool pool of equipment allows a fast repair of the pipelines.

• Statoil has on behalf of the owner group enteredStatoil has on behalf of the owner group entered into necessary contracts to ensure the system is operational at all times.

Morgrip Pipeline ConnectorsMorgrip Pipeline Connectors• MORGRIP is a sleeve type pipeline coupling

with integral sealing & pipe gripping system

T i S l I t it• Twin Seal Integrity

• External Seal Test Capability

• Metal and graphite sealing material –Metal and graphite sealing material resistant to all media

• Pipe end is abutted with internal shoulder / pipe ends & pre-loaded with compressive p pe e ds & p e oaded t co p ess eforces

• Load path of external loads is through balls and bolts – seals & abutment are isolated from these effects

• 1” to 42” pipe

Recipe for failure:

Lack of available equipment• Lack of available equipment

• Lack of planning (environmental, installation procedures, government approvals etc )approvals etc.)

• Uncoordinated / disjointed approach

• Unskilled personnelp

• Lack of inter-company cooperation

• People don’t plan to fail, but we can be accused of failing to plan!
