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.

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 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.

Allseas giant platform removal and installation vessel removed the 13,500-tonne topsides of the Yme platform on 22 August 2016
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...
Load out operations of the DolWin alpha topsides from Heerema's Zwijndrecht fabrication yard at the Drechthaven, located on the river Oude Maas. This operation marks the start of a journey that the platform will make, via Schiedam, to its final offshore destination, the DolWin area in German North Sea. Here it will be positioned on top of the already installed jacket in July 2013. The platform of DolWin1 was built by Heerema Fabrication Group's Zwijndrecht yard, as a subcontractor of TenneT's main contractor ABB. The platform is 45 metres wide, 77 metres long and approx. 80 metres high (from the waterline to the top of the crane) and weighs more than 9,000 metric tonnes.
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.

In this presentation, Subhash Gangahar, Topside Engineering Manager at MODEC, describes the essential steps towards design optimization. This presentation was delivered at the FPSO World Congress 2015 in Singapore. For more articles, presentations and videos about the FPSO industry, visit: www.fpsonetwork.com
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 Montrose Bridge Linked Platform was constructed at Heerema Zwijndrecht. The construction of the topside started in March 2013 and was completed within three years. End April 2016 the project was transported to the offshore location and installed by HMC's crane vessel Thialf.
Watch the jacket for one of the Shah Deniz Stage 2 platforms sail away for its offshore installation in the Caspian Sea. The sail away from the Heydar Aliyev Baku Deepwater Jackets Factory was attended by H.E. President Ilham Aliyev of the Republic of Azerbaijan.

When Statoil & partners decided to develop the Mariner heavy oil field east of the Shetland Islands in December 2012 it was the largest capital commitment to the UK continental Shelf (UKCS) in more than a decade. The platform itself is quite big as well! The topside includes both drilling and processing facilities as well as living quarters and was built by DSME in South Korea. It weighs more than 38 000 tonnes, more than five times the steel weight of the Eiffel Tower. To be able to lift it on to the steel jacket already in place at the field, it’s divided into eight modules and a flare to be transported on no less than five heavy transport vessel. In April the load out operations started and 2. May the first heavy transport vessel headed for UK and this summer all the pieces will be pu...

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.
