On an offshore oil platform, topsides (c.f. jacket structure, which constitutes the lower half of the platform structure, partly submerged in sea) refers to the upper half of the structure, above the sea level, outside the splash zone, on which equipment is installed. This includes the oil production plant, the accommodation block and the drilling rig. They are often modular in design and so can be changed out if necessary allowing expensive platforms to be more readily updated with newer technology.

The Wheatstone Project successfully completed one of the largest offshore platform installations in Chevron's history, marking a major project milestone. Watch the journey of the Wheatstone topsides from fabrication to load-out, the sail-away, the arrival and the float-over onto the steel-gravity structure base. The Wheatstone Platform is the largest offshore gas processing platform ever installed in Australia, with a topsides weight of about 37,000 metric tons and the largest float-over installation Chevron has ever delivered globally.

http://www.oceanicmc.com/ Oceanic 5000 is a DP2 Derrick Lay Vessel which can install offshore structures including jackets and topsides weighing up to 4400MT. The state-of-the-art Oceanic 5000 can also lay subsea pipelines utilizing her two double-joint stations resulting in considerable increase in lay rates. This video demonstrates installation of a 2000t jacket by launching method and a 1500t topside (deck) by lifting method. The entire pipe lay assembly process is carried out below the main working deck. This allows maximum pipe storage above deck and more free deck space for structural installation; thereby providing a safer and more productive working condition. The vessel is equipped with a specially-designed “piggy-back” system for the installation of carrier pipes to be simulta...

The Troll A platform is a condeep offshore natural gas platform in the Troll gas field off the west coast of Norway. It is the tallest structure that has ever been moved to another position, relative to the surface of the Earth, and is among the largest and most complex engineering projects in history. The platform was a televised sensation when it was towed into the North Sea in 1996, where it is now operated by Statoil. Troll A was built by Norwegian Contractors for Norske Shell, with base construction beginning in July 1991 at a cost of 4150 million NOK, or approximately US$650,000,000 at the time. The base and the deck were built separately, and were joined in 1995 while the base was partially submerged. The base is a Condeep gravity base structure built from reinforced concrete. The...
Lundin Norway has successfully completed the installation of the topside modules on the Edvard Grieg field, offshore Norway. The Edvard Grieg topside installation consisted of lifting four modules onto the pre-installed jacket – the main deck frame, the utility and living quarters module, the processing module and the flare boom with a total weight of 22,000 tonnes. The lift operation was carried out by Heerema’s heavy lift vessel Thialf.

The Mariner A topside is now complete! On 2 August the final piece of the giant puzzle was lifted into place on the 38 000 tonne topside. The topside consists of eight modules, two of them more than 10 000 tonnes. The flare, a crane and some stair towers have also been installed offshore by heavy lift vessel Saipem 7000. Now the floatel Safe Boreas is connected to the platform and the two million man hour topside scope can begin. The Mariner field is expected to come on stream late 2018.
19,000 tonnes of jacket, 7,000 tonnes of piles and 20,000 tonnes of topsides. All completed in 2013. Unofficial video by a budding installation engineer; professional video also available on youtube. West Chirag PDQ Operator: BP (on behalf of AIOC) Installation contractor: Saipem Music by Deadmau5

Offshore platforms are remarkable engineering feats, therefor it is time for the 5 largest offshore platforms of the world! Massive in size, these structures take several years and often many billions of dollars to build — but when complete, they can extract oil and gas from some of the least-accessible spots on the planet. The Mars B/Olympus Platform in the Gulf of Mexico First oil production begun in February 2014 from the Mars B development through Olympus, Shell’s seventh, and largest, floating deep-water platform in the Gulf of Mexico. Combined production from Olympus and Shell’s original Mars platform is expected to deliver an estimated resource base of 1 billion barrels of oil equivalent (boe). The project is also directly investing $5 million dollars in community, social and env...
The 24 000 tonne topside for the Aasta Hansteen gas platform arrived in Norway on 30 November after a 14 500 nautical mile long journey. That’s equivalent to nearly 26 900 km, or more than 640 marathons! The lady was brought home to Norway by Dockwise White Marlin. In Ølensvåg the topside will be transferred to two new vessels that will take it to Stord to be mated with the substructure, creating the world’s largest spar-platform.
The topsides lift was executed safely and successfully at Ingleside, TX earlier this year.
A $40-million (U.S.) engineering structure belonging to Iran's South Pars gas field to be used in offshore platforms sank into the Gulf as it was being installed, media reports said on Wednesday. "An investigation is under way," Maritime Industrial Co. (SADRA) managing director Mehdi Etesami told the ISNA news agency, without giving an official reason for the incident.Iran later called for foreign help to recover the gas platform from the seabed, its Mehr news agency reported, in a rare request by an industry isolated by sanctions. The equipment was built by SADRA, an affiliate of the industrial wing of Iran's Revolutionary Guards, over a 30-month period. The incident occurred Monday night as the 1,850-tonne jacket developed for South Pars Phase 13 sank to a depth of 80 metres, media re...
In less than a week all the modules for the Gina Krog topside was installed at the field in the North Sea in August 2016 by Saipem 7000. The complete weight of the topside is close to 20 000 tonne. The main support frame, process module and utility module was constructed by DSME at Okpo, South Korea, the living quarter was constructed by Apply Leirvik at Stord, Norway. The Gina Krog platform will come on stream in 2017.
Hundreds of people worked around the clock to successfully install the 10,000-ton topsides on Anadarko's floating Lucius truss spar. This massive structure is located nearly 275 miles southeast of Galveston, Texas in approximately 5,300 feet of water in the Gulf of Mexico. The successful setting of the topsides brought together a tapestry of components built in Orange, Texas; Houma, La; and Ingleside, Texas, among other locations worldwide. Lucius is Anadarko's largest spar to date with a nameplate capacity of 80,000 barrels of oil per day.
