Civil law – but could be adapted easily to common law jurisdiction.

Dispute resolution – negotiation, then adjudication, then arbitration (1.8).


No assignment of the contract by Operator without the prior consent of the Owner (1.9).


Suspension and Termination (19) – allows for termination at the Owner’s convenience – provided compensation paid.  Relatively usual provisions regarding termination for owner and operator default.

Possible additional provisions that it might be appropriate to include:

This is a well-drafted balanced contract but it would be helpful to include specific provisions regarding handover of assets and personnel.

Provisions that may not be advisable to replicate/ may need further thought:

It might not be appropriate in all cases to use adjudication as the dispute resolution mechanism.

Provisions of wider general use:

Most of the provisions could be replicated.
