摘要:
Disclosed herein is a controlled method of minimizing radioactive sludge generation in treatment of wastewater from an oil and/or gas well. The method comprises measuring a concentration of a radioactive material in wastewater to be treated and measuring a concentration of barium in the wastewater to be treated. The method further comprises adding a calculated quantity of sulfate to the wastewater to be treated sufficient to precipitate a quantity of barium sufficient to reduce the concentration of the radioactive material to a level such that sludge precipitated in a secondary precipitation has a radiation level below a defined radiation level.
摘要:
A vessel is provided that is an improvement over previously disclosed jack-up rigs and lift boats. The vessel has at least three thrusters and is self-propelled. The vessel additionally has a raised and hollow crane support on which a crane may be mounted. The crane support is preferably affixed to tracks, which permit the crane to slide along the deck of the vessel. The raised and hollowed feature of the crane support permits the storage of equipment and things beneath the crane support without hindering the movement of the crane along the tracks. Optionally, the vessel further has an extension assembly atop which may be deployed a workover rig assembly. The crane may be used to assemble the extension assembly and thus aid in the construction, remediation, and demolition of offshore oil and gas platforms and wells.
摘要:
A method is described for storing and retrieving reports from a computer database with control of access to the database and to the reports. The reports are stored in a current database (16) for a selected period of time and are stored in a library database (18) on a permanent basis. The reports are provided in a report configuration which has data elements of the same parameter at specified locations according to the report configuration. When a report is received for storage in the database, indices are generated relating data elements of various data parameters to memory location of such data elements in the storage locations of the database. The indices can be used to retrieve portions of the report of interest. Access to the database is controlled by report type, report date, and report segment.

摘要:
An extension bridge is provided that comprises at least one modular tank affixed to the deck of a vessel, and a pipe bridge spanning the distance between the at least one modular tank and an offshore platform. Alternatively, the extension bridge comprises spaced apart first and second extension beams, which are removeablely and independently affixed to the deck of a vessel. At least a portion the first and second extension beams extend beyond the transom of the vessel. The extension bridge further includes at least one modular tank affixed to the first and second extension beams and a pipe bridge affixed to the at least one modular tank furthest from the vessel and an offshore structure.
摘要:
A method of passing a pipe from a first vessel to a second vessel using an arm assembly affixed to the second vessel is provided herein. The method includes moving the second vessel within proximity of the first vessel and anchoring, or pinning, the second vessel. The arm assembly of the second vessel is moved toward the pipe, until the pipe is secured, or disposed, therein. The first vessel then releases the pipe.
