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.

Allseas giant platform removal and installation vessel removed the 13,500-tonne topsides of the Yme platform on 22 August 2016
Allseas' dynamically positioned single-lift installation/decommissioning and pipelay vessel “Pioneering Spirit” set a world lifting record with the safe and
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.

The topsides lift was executed safely and successfully at Ingleside, TX earlier this year.
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.
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.
McDermott constructed the 17,000-ton Central Azeri Topsides for the ACG Full Field Development in the Caspian Sea, and handled assembly, hook-up and commissioning of the integrated drilling/quarters/production deck. Topside fabrication was done primarily in Azerbaijan at Baku Deepwater Jack Factory (BDJF), a fabrication yard owned by the State Oil Company of the Azerbaijan Republic, utilizing key local Azerbaijani infrastructure, equipment and workers. The contract included upgrading plant and equipment at BDJF before actual construction of the topsides began. Local Azerbaijanis contributed to more than 80% of the project.
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.
The seamless integration of McDermott's worldwide capabilities and innovative float-over installation technology ensured schedule certainty of this large integrated topside offshore Thailand. McDermott undertook construction, load out, pre-commissioning, transportation, float-over installation, and hook-up of the 17,000-tonne integrated topsides, and 5,000-tonne jacket. Arthit Central Processing Platform was a major project initiative for the development of natural gas resources in the Gulf of Thailand.
