10. Oil pipe lines on petroleum wharfs shall be steel or wrought iron pipe of a grade suitable for service, shall be reasonably protected against mechanical injury, and shall be installed, supported, and maintained as necessary to safely withstand the stresses imposed by internal and external loads and by contraction, expansion, vibration, or subsidence.
11. Pipelines from the pump to the wharf shall be tested annually for tightness at a pressure not less than 150% of the maximum pumping pressure. The Terminal Operator shall certify in writing to the Chief, when and at what pressure the pipelines were tested. All piping installed, renewed, or rearranged between shore and petroleum wharfs of timber construction shall be provided with approved means to permit independent movement of the wharf or shore piping without excessive strain on the pipe.
12. Each cargo hose shall be provided with a means of support which will prevent chafing or kinking during transfer operations. All cargo hose shall be capable of withstanding a pressure equal to the maximum working pressure of the system on which it is used. Cargo hose shall be tested at least once each year at a pressure at least as great as the pressure of the relief valve setting (or maximum pump pressure when no relief valve is installed), plus any static heat pressure of the system in which the hose is used, and a record of such tests shall be maintained at the terminal.
13. Pans or buckets shall be placed under all hose couplings when in use. Ends of pipelines on wharf and vessel shall be blind flanged.
