You must take the following safety measures when you conduct operations with a rig unit on or jacked-up over a platform with producing wells or that has other hydrocarbon flow:
(a)The movement of rig units and related equipment on and off a platform or from well to well on the same platform, including rigging up and rigging down, must be conducted in a safe manner;
(b)You must install an emergency shutdown station for the production system near the rig operator's console;
(c)You must shut-in all producible wells located in the affected wellbay below the surface and at the wellhead when:
(1)You move a rig unit or related equipment on and off a platform. This includes rigging up and rigging down activities within 500 feet of the affected platform;
(2)You move or skid a rig unit between wells on a platform; or
(3)A MODU moves within 500 feet of a platform. You may resume production once the MODU is in place, secured, and ready to begin operations.
(d)All wells in the same well-bay which are capable of producing hydrocarbons must be shut-in below the surface with a pump-through-type tubing plug and at the surface with a closed master valve prior to moving rig units and related equipment, unless otherwise approved by the District Manager.
(1)A closed surface-controlled subsurface safety valve of the pump-through-type may be used in lieu of the pump-through-type tubing plug provided that the surface control has been locked out of operation.
(2)The well to which a rig unit or related equipment is to be moved must be equipped with a back-pressure valve prior to removing the tree and installing and testing the BOP system.
(3)The well from which a rig unit or related equipment is to be moved must be equipped with a back pressure valve prior to removing the BOP system and installing the production tree.
(e)Coiled tubing units, snubbing units, or wireline units may be moved onto and off of a platform without shutting in wells. \[81 FR 26022, Apr. 29, 2016, as amended at 84 FR 21977, May 15, 2019\]
