An oil platform is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed. Many oil platforms will also have facilities to accommodate the workers, although it is also common to have a separate accommodation platform bridge linked to the production platform. Most commonly, oil platforms engage in activities on the continental shelf, though they can also be used in lakes, inshore waters, and inland seas. Depending on the circumstances, the platform may be fixed to the ocean floor, consist of an artificial island, or float. In some arrangements the main facility may have storage facilities for the processed oil. Remote subsea wells may also be connected to a platform by flow lines and by umbilical connections. These sub-sea facilities may include one or more subsea wells or manifold centres for multiple wells.
Offshore construction is the installation of structures and facilities in a marine environment, usually for the production and transmission of electricity, oil, gas and other resources. It is also called maritime engineering.
A monitor is a relatively small warship that is neither fast nor strongly armored but carries disproportionately large guns. They were used by some navies from the 1860s, during the First World War and with limited use in the Second World War.
A semi-submersible platform is a specialised marine vessel used in offshore roles including as offshore drilling rigs, safety vessels, oil production platforms, and heavy lift cranes. They have good ship stability and seakeeping, better than drillships.
A platform supply vessel (PSV) is a ship specially designed to supply offshore oil and gas platforms and other offshore installations. They typically range from 50 to 100 metres in length and are distinguished by the large open deck area used to store supplies and house equipment and to allow for efficient loading and offloading. The primary function for most of these vessels is logistic support and transportation of goods, tools, equipment, and personnel to and from their destination.
Anchor Handling Tug Supply (AHTS) vessels are mainly built to handle anchors for oil rigs, tow them to location, and use them to secure the rigs in place. AHTS vessels sometimes also serve as Emergency Response and Rescue Vessels (ERRVs) and as supply transports.
A diving support vessel is a ship that is used as a floating base for professional diving projects. Basic requirements are the ability to keep station accurately and reliably throughout a diving operation, often in close proximity to drilling or production platforms, for positioning to degrade slowly enough in deteriorating conditions to recover divers without excessive risk, and to carry the necessary support equipment for the mode of diving to be used.
A Z-drive is a type of marine propulsion unit. Specifically, it is an azimuth thruster. The pod can rotate 360 degrees allowing for rapid changes in thrust direction and thus vessel direction. This eliminates the need for a conventional rudder.
The Saipem 7000 is the world's third largest semi-submersible crane vessel, after the SSCV Sleipnir and the SSCV Thialf. It is owned by the oil and gas industry contractor Saipem S.p.A.
Mazagon Dock Shipbuilders Limited (MDL), formerly called Mazagon Dock Limited, is a shipyard situated in Mazagaon, Mumbai. It manufactures warships and submarines for the Indian Navy and offshore platforms and associated support vessels for offshore oil drilling.

MacGregor Pusnes formerly known as Aker Pusnes, Aker Kværner Pusnes and Maritime Pusnes, established in 1875, is a designer and supplier of all types of deck machinery and mooring systems for marine and offshore applications. In addition, Aker Pusnes has developed and supplied bow loading and offloading systems for both simple and sophisticated operations offshore. The company is a subsidiary of Aker Solutions and located on Tromøya island near the city of Arendal in Aust-Agder county, Norway.
A liftboat is a self-propelled, self-elevating vessel used in support of various offshore mineral exploration and production or offshore construction activities. A liftboat has a relatively large open deck to accommodate equipment and supplies, and the capability of raising its hull clear of the water on its own legs so as to provide a stable platform from which maintenance and construction work may be conducted.
SCF Sakhalin is a Russian icebreaking platform supply and standby vessel owned by SCF Sakhalin Vessels Limited, a subsidiary of Sovcomflot. The ship was built by Aker Finnyards Helsinki shipyard in Finland in 2005 as FESCO Sakhalin for Far East Shipping Company (FESCO), but was purchased by Sovcomflot and renamed in 2010. Since the beginning it has been in long-term charter for Exxon Neftegas Ltd. and used to supply oil platforms in the Sakhalin-I project.
SS Great Republic was a sidewheel steamship and the largest passenger liner on the US west coast when it ran aground near the mouth of the Columbia River, on Sand Island, south of Ilwaco, Washington, in 1879, in a region of frequent wrecks known as the Graveyard of the Pacific.
TSS (RMS) Mona's Queen (III) No. 145308, was a ship built for the Isle of Man Steam Packet Company in 1934. The steamer, which was the third vessel in the company's history to bear the name, was one of five ships to be specially commissioned by the company between 1927 and 1937. They were replacements for the various second-hand steamers that had been purchased to replace the company's losses during the First World War. However, the life of the Mona's Queen proved to be short: six years after being launched she was sunk by a sea mine during the Dunkirk evacuation on 29 May 1940.
Vitus Bering is a Russian icebreaking platform supply and standby vessel owned by Sovcomflot. Built by Arctech Helsinki Shipyard in Helsinki, Finland, she and her sister ship, Aleksey Chirikov, were ordered on 16 December 2010, shortly after the joint venture agreement between STX Finland Cruise Oy and United Shipbuilding Corporation had been signed. Delivered to the owners on 21 December 2012, Vitus Bering is used in the Arkutun-Dagi offshore oil field in the Sea of Okhotsk.
Arcticaborg (Арктикаборг) is an icebreaking platform supply vessel. She was previously operated by Wagenborg Kazakhstan in the Caspian Sea but was transferred to Canada in 2017 and acquired by Fathom Offshore in 2018. In 2019, she was contract to Russia for two years.
A crew boat, also called a crewboat, crew transfer vessel, fast support vessel,fast supply vessel or fast intervention supply vessel, is a vessel specialized in the transport of offshore support personnel, deck cargo, and below-deck cargo such as fuel and potable water to and from offshore installations such as oil platforms, drilling rigs, drill and dive ships or wind farms.
Aleksey Chirikov is a Russian icebreaking platform supply and standby vessel owned by Sovcomflot.
