Svalbard and Jan Mayen (Norwegian: Svalbard og Jan Mayen, ISO 3166-1 alpha-2: SJ, ISO 3166-1 alpha-3: SJM, ISO 3166-1 numeric: 744) is a statistical designation defined by ISO 3166-1 for a collective grouping of two remote jurisdictions of Norway: Svalbard and Jan Mayen.

The United Nations Statistics Division also uses this code, but has named it the Svalbard and Jan Mayen Islands. Svalbard is an archipelago in the Arctic Ocean under the sovereignty of Norway, but is subject to the special status granted by the Svalbard Treaty.
ISO 3166-2:SJ is the entry for Svalbard and Jan Mayen in ISO 3166-2, a system for assigning codes to subnational administrative divisions. However, further subdivision for Svalbard and Jan Mayen occurs under Norway's entry, ISO 3166-2:NO:
Svalbard and Jan Mayen have in common that they are the only integrated parts of Norway not allocated to counties. While a separate ISO code for Svalbard was proposed by the United Nations, it was the Norwegian authorities who took initiative to include Jan Mayen in the code. Its official language is Norwegian.
Svalbard possesses community life today precisely because the Svalbard Treaty was unable to provide Norway with unambiguous and lasting sovereignty over the islands. A contrast is provided by the remote Arctic island of Jan Mayen, which Norway succeeds in maintaining jurisdiction over even in the absence of a permanent population.

Accumulators are ASME-coded pressure vessels for the storage of high-pressure fluid. These accumulators as a part of the BOP control unitare available in a variety of sizes, types, capacities, and pressure ratings. The two (2) basic types are bladder and float which are available in cylindrical or ball styles. The accumulators. . Accumulator bottles are containers that store hydraulic fluid under pressure for use in effecting blowout preventer closure. Through the use of compressed nitrogen gas, these containers. . As a minimum requirement, all blowout preventer control units should be equipped with accumulator bottles with sufficient volumetric capacity to provide the usable fluid volume (with pumps inoperat. . The closing system should be capable of closing each ram preventer within 30 seconds. Closing time should not exceed 30 seconds for annular preventers smaller than 18 3/4 inches and 45 seconds for annular preventers 18 3/4. [pdf]
The accumulator should have sufficient volume to close/open all preventers and accumulator pressure must be maintained all time. According to API RP53, your reservoir tank should have a total volume at least 2 times of usable volume to close all BOP equipment.
The BOP control unit contains up to a several dozen accumulators of 10 gal or larger size. The accumulator vessels are made of carbon steel designed to withstand pressures in the range of 3,000 psi. Inside is a bladder made of nitrile compound (BUNA-N) or other material as appropriate.
In the float type BOP accumulator, the gas is introduced at the top of the bottle and is kept separate from the stored fluid by a buoyant float. The escape of the gas through the fluid port at the base of the bottle is contained by the weight of the float actuating a shut-off valve once all the fluid has been ejected.
SYSTEMA regular scheduled maintenance program must be developed to suficiently maintain the BOP Accumul tor Control System. The operator must develop the appropriate pro-gr m based on his operating, testing and drilling programs. The entire control system should be tested a minimum
Every component of your BOP Drilling Accumulator Control Unit is expertly designed to provide you with reliable hydraulic power when you need it. MEYER is your go-to source for all your BOP testing needs and BOP equipment, like our BOP Control Systems here.
The accumulator shall be located at a remote location, at least 60 feet distance from the wellbore for oil wells and 100 feet for gas wells, shielded from the wellhead and protected from other operations around the rig. There must be at least two (2) sets of remote controls for operating the accumulator to activate the BOPs.
