5. The operator shall ensure that a fluid is not conveyed in the pipeline unless the pipeline has been so designed that, so far as is reasonably practicable, it can withstand—
(a)forces arising from the pipeline’s operation;
(b)the fluids that may be conveyed in the pipeline; and
(c)the external forces and the chemical processes to which the pipeline may be subjected.
6. The operator shall ensure that a fluid is not conveyed in a pipeline unless the pipeline has been provided with such safety systems as are necessary for securing that, so far as is reasonably practicable, persons are protected from risk to their health or safety.
7. The operator shall ensure that a fluid is not conveyed in a pipeline unless the pipeline has been so designed that, so far as is reasonably practicable, it may be examined and work of maintenance may be carried out safely.
8. The operator shall ensure that a fluid is not conveyed in a pipeline unless the pipeline is composed of materials which are suitable.
9. The operator shall ensure that a fluid is not conveyed in a pipeline (save for the purpose of testing it) unless the pipeline has been so constructed and installed that, so far as is reasonably practicable, it is sound and fit for the purpose for which it has been designed.
10. The operator shall ensure that modification, maintenance or other work on a pipeline is carried out in such a way that the pipeline’s soundness and fitness for the purpose for which it has been designed will not be prejudiced.
11. The operator shall ensure that—
(a)a fluid is not conveyed in a pipeline unless the safe operating limits of the pipeline have been established; and
(b)a pipeline is not operated beyond its safe operating limits,
save for the purpose of testing it.
12. The operator shall ensure that a fluid is not conveyed in a pipeline unless adequate arrangements have been made for dealing with—
(a)an accidental loss of fluid from the pipeline;
(b)discovery of a defect in or damage to the pipeline; or
(c)any other emergency affecting the pipeline.
13. The operator shall ensure that a pipeline is maintained in an efficient state, in efficient working order and in good repair.
14.—(1) The operator shall ensure that a pipeline which has ceased to be used for the conveyance of any fluid is left in a safe condition.
(2) The operator of a pipeline shall ensure that work done in discharge of the duty contained in paragraph (1) is performed safely.
15. A person shall not cause such damage to a pipeline as may give rise to a danger to persons.
16. For the purpose of ensuring that no damage is caused to a pipeline, the operator shall take such steps to inform persons of its existence and whereabouts as are reasonable.
17. Where there are different operators for different parts of a pipeline, each operator shall co-operate with the other so far as is necessary to enable the operators to comply with the requirements of these Regulations.
