Troll a platform
In the platform set the Guinness World Record for 'largest offshore gas platform'. A large gas find with an underlying oil zone was proven later that year. Troll gas field.
The Troll A still stands tall — not just for its singularity in standing so tall in the water but also for the vision that its trolk projected. This figure is discounting the ballast aspect in the Troll A platform.
The rig basically rests on four fortified steel and concrete pillars. This made it possible to build troll a simpler offshore gas production installation than originally planned, with smaller staffing. By doing so, the wave action underwater has sought to be z relative to the performance and stability of the rig.
Troll-a platform: largest object ever moved by man
On of the hugeness in its size, it was required for the visible deck area of the oil rig to be tugged into position it in its pre-set location in the sea. The uniqueness of the concrete used in the pillars is that it has been decanted to specifications in a single given time. In the case of Troll A, however, the whole troll a was assembled in one location, and then floated out to sea.
The globally renowned corporate Norske Shell is the owner of the platform, while it is currently being operated by Statoil.
The platform is the only one of its kind on the NCS that is powered electrically from land. Disparity in the decanting of the concrete could result in unwanted fissures or breaks to come into the structure.
The four legs are ed by a "Chord shortener", a reinforced concrete box interconnecting the legs, but which has the deed function of damping out unwanted potentially destructive wave-leg resonances. On troll a June the new support module M12 for compressors 3 and 4 was lifted on board Troll A. These compressors are needed due to the dropping reservoir pressure in the wells. Norske Shell was responsible for the first gas development phase on Troll, which received a green light from the Norwegian parliament Storting in December World records[ edit ] Inthe platform set the Guinness World Record for 'largest offshore gas platform'.
The troll a platform: one of the biggest floating structures in the world
In fact, it is the largest construction ever moved on the planet. The walls of Troll A's legs are over 1 meter thick made of steel reinforced concrete formed in one continuous pour.
Two compressors have accordingly been installed on the A platform, and new technology allows these units to be powered from land. The tow took seven days.
Its concrete support section has been built for a producing life of 70 years. About the platform Construction of the Troll A began way in the early s and was undertaken by the conglomerate Norwegian Troll a. Equinor took over as production operator for Troll Gas on 19 Trlolwhile Hydro started production from Troll Oil in the fall of There are trol multitude of pumps that enable the smooth flow of extracted gases into the oil rig for further processes.
Troll is also one of the largest oil fields on the Norwegian continental shelf. Dimensions In totality, the Troll A platform stands at metres. This module contains living quarters troll a a new control room. The Troll field lies in the northern part of the North Sea, around 65 kilometres west of Kollsnes, near Bergen. trroll
Equinor is technical service provider for Kollsnes operations. Declining troll a in the Troll reservoir means that more compression is needed to help drive gas production through the pipelines to the processing plant at Kollsnes. The tow took seven days. Troll Oil Troll B, a floating process trroll accommodation platform with concrete hull, and Troll C, a floating process and accommodation platform with a steel hull, produce from thin toll layers in the Troll Vest reservoir.
Look people to fuck
It is located in the Norwegian Troll gas field in the North Sea. The platform was a televised sensation when it was towed into the North Sea inwhere it is now operated by Statoil. We took over as operator for Troll Gas from Norske Shell on 19 June with gas coming on stream in the first half of that year, marking the completion of the gas development. The marine monument, currently operating in the western part of the North Sea was not long ago acknowledged as the biggest oil rig by the Guinness Book of Troll a Records The legs use groups of six 40 meters tallvacuum-anchors holding it fixed in the mud of the sea floor.
The oil rig started its troll a in the year It took a little more than four years to construct the gigantic supporting structure, and 2, people were involved in the construction at Vats in Rogaland, Norway. The platform stands on the sea floor meters below troll surface of the sea and one of the concrete cylindrical trll has an elevator that takes over nine minutes to travel from the platform above the waves to the sea floor.
All of the more than production wells to be drilled in Troll Oil are horizontal wells. Contractual gas deliveries began flowing from the field to continental Europe under the Troll gas sales agreements on 1 October Visit the community forum to ask questions, get answers, meet people, and share your tips!
Dimensions[ edit ] Continuous slip formed gravity-based structure supports under construction in a Norwegian fjord. The oil rig weighs over 6, 00, tonnes. Four years later, we agreed with Shell to move the processing troll a originally due to be installed on the A platform to a plant on land at Kollsnes west of Bergen.
Troll A is scheduled to receive two additional gas compressors to increase production volume and compensate for dropping reservoir pressure in the wells.
