Reference excerpt

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 Italian oil and gas industry contractor Saipem S.p.A.

History

Construction The vessel was designed by Gusto Engineering during 1984. The vessel was built between 1985 and 1987 by Fincantieri-Cantieri Navali Italiana S.p.A. at their Monfalcone yard, Trieste in north-eastern Italy. The vessel was built in two halves in a long dry dock. The halves were then floated out from the dry dock and mated. During the mating operation the halves were supported by temporary pontoons. The hull mating was complete in early 1987 and the two cranes built by Officine Meccaniche Reggiane under subcontract to American Hoist & Derrick Company (Amhoist) were installed in sections by the Saipem crane vessel Castoro Otto in April of that year. The sea trials, which took two months, started in September, and on 15 December the vessel was handed over to Micoperi. The cost of the vessel was not released by Micoperi but it was estimated in the technical press as being up to US$400 million.

Early projects The vessel's first work was for Petrobras the Brazilian state oil company. The project consisted of the installation of 7 platforms in the Campos Basin. During this project the Micoperi 7000 was also involved in the fighting of a well fire on the Enchova Platform. The Micoperi 7000 then proceeded to the Gulf of Mexico where it installed the Jolliet Template for Conoco. In 1989 the Micoperi 7000 arrived in the North Sea for the first time where it completed several projects in the Norwegian sector of the North Sea. These were the Gyda Platform for BP, the Togi Template for Norsk Hydro and the Veslefrikk platform for Statoil. In 1990 and 1991, the Micoperi was used in the construction and assembly of the Mossgas FA platform off the south coast of South Africa near a town called Mossel Bay. Whilst the vessel remained busy, Micoperi were struggling financially as the low oil price prevalent in the late 1980s curtailed oil company investment. In 1991 Micoperi were forced to sell a number of their major assets including the Micoperi 7000 to another Italian contractor Saipem. Saipem took over the running of the vessel though they retained the vessel crew and the shorebased engineering support. Saipem renamed the vessel the Saipem 7000. The vessel continued to work, installing oil and gas production platforms, in the North Sea, Gulf of Mexico, off the Canadian east coast and the west coast of Africa throughout the nineties. It was also involved in the removal of one platform, the Esso Odin. During the late nineties Saipem planned an upgrade to the vessels DP system and installation of a J-Lay system.

Recent projects The Saipem 7000 has completed 4 J-Lay pipe projects Diana, Blue Stream, Ormen Lange and Medgaz, but its main work continues to be heavy lift in the North Sea and the Gulf of Mexico. This includes both platform installation and removal and the addition of modules to existing platforms. It is currently deployed in the North Sea, approximately 27km east of Montrose, Scotland, installing the 114 jacket foundations for Seagreen offshore wind farm.

Incident in Norway On 14 April 2022, the vessel suffered a lifting accident in a Norwegian fjord near Stavanger during a planned load test of the cranes. The main block wire broke, dropping a barge used as test weight. This caused the vessel to tilt, but was soon stabilized. Nobody was injured during the incident.

Incident in Rotterdam In February 2024, while due to undergo repair work, Saipem 7000 had a fatal allision with a small vessel in the Port of Rotterdam. The Incident Report from the Dutch Safety Board stated that Rotterdam's pilots and the ship repair yard should carry out better planning before navigational evolutions in confined harbours.

Lifting and pipelaying records The Saipem 7000 set the world offshore lifting record of 12,150 tons for the Sabratha deck in the Mediterranean Sea. A local record for the Gulf of Mexico (Mexican area) was set with the 10,473 tons of the PB-KU-A2 deck. In July 2010, the Saipem 7000 broke another world record by lifting the new BP Valhall Production and Hotel topside of approximately 11,600 tonnes on Dynamic Positioning. The previous world record set at Sabratha was performed on the vessel's anchoring system. The first and third records were broken on 7 September 2019 when the Sleipnir lifted the 15,300 ton deck module for Noble's Leviathan. The Saipem 7000 laid the 24" pipeline for the Blue Stream project between Russia and Turkey up to the record depth of 2,150 meters in the Black Sea. This was broken at the end of 2005 by the Balder which laid a pipeline in 2,200 meters of water, yet Balder was outbeat herself in 2014 by another laybarge of Saipem, the FDS2, which laid another 24" pipeline in 2,250 meters offshore Brazil.

Description

Concept The Saipem 7000, originally named the Micoperi 7000, was conceived in the mid-1980s by its original owners Micoperi as a multipurpose offshore oil platform installation vessel that would be able to install very large oil production platform decks (known as integrated decks) as well as the decks' supporting structures (known as jackets) using its two very large fully revolving cranes. It would also be able to support the offshore completion of the platform by providing hotel and workshop facilities for large construction crews. Saturation diving facilities would support subsea connection work. The vessel's size and semi-submersible form would allow it to operate in worse weather conditions than smaller and conventionally shaped vessels. The huge cost of a vessel of this size would be offset by the cost and time savings made by the oil company as the large integrated decks could be completed, tested and commissioned onshore. Prior to the introduction of the large crane vessels, offshore oil platforms were made up of 1000 - 2000 tonne modules which were lifted into place individually by smaller SSCVs or monohull crane vessels and then connected together offshore, tested and then commissioned; this often took over a year. Other savings in the installation of the jackets could also be made.

Worked examples

Example 1 — a first encounter with Saipem 7000

Start with the simplest possible case. Write down what Saipem 7000 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Saipem 7000 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Saipem 7000 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Saipem 7000

In research: Saipem 7000 appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Saipem 7000 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Saipem 7000 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1986 ships, Coastal construction, Crane vessels, so understanding it makes those chapters shorter.
In everyday life: Look for Saipem 7000 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
