Allseas Group S.A. is a Swiss-based offshore contractor specialising in pipelay, heavy lift and subsea construction.[1] The company, founded in 1985 by owner and president Edward Heerema, employs 3,000 people and operates worldwide.

Overview[edit]

Allseas is an international offshore contractor specialising in the execution of large and complex projects, covering pipeline installation, platform installation and removal, and the installation of subsea infrastructure. The company provides support to clients already in the conceptual design stage and offer services for project management, engineering, fabrication, procurement, installation and commissioning.

The Allseas Group is headquartered in Châtel-Saint-Denis, Switzerland. Allseas Engineering B.V. with offices in Delft, Eindhoven and Enschede, the Netherlands, provides project management and engineering services to the group. The company also operates project and engineering offices out of Australia, Brazil and the USA.[2]

Allseas operates a versatile fleet of specialised heavy-lift, pipelay and subsea installation vessels designed and developed in-house. Allseas has installed over 20,000 km of subsea pipeline worldwide using S-lay technology, with diameters ranging from 2" to 48".[3] The company's first vessel, Lorelay, was launched in 1986, and was the world's first pipelay vessel to operate on full dynamic positioning.[4]

In 1998 Allseas added the 300 m long Solitaire to its fleet.[5] The vessel has a pipe carrying capacity of 22,000 t and has achieved pipelay speeds in excess of 9 km per day. In 2006, while working on the Atwater Valley and Independence Trail projects in the Gulf of Mexico, Solitaire set new depth records, laying 10-inch pipeline in 2775 m (9100 ft) water depth and 24-inch pipeline in 2550 m (8370 ft) water depth.[6]

Allseas owns and operates a specialised heavy-lift, pipelay and subsea installation vessels designed and built in-house.

Allseas’ latest vessel, the 382 m long, 124 m wide dynamically positioned platform installation / removal and pipelay vessel Pioneering Spirit, entered service in August 2016. With a topsides lift capacity of 48,000 t, a jacket lift capacity of 25,000 t and a motion compensation system, the vessel can install and remove topsides and jackets in a single lift in wave heights up to 2.5 m significant.[7] Pioneering Spirit set a world offshore lifting record of 13,500 t with her first commercial lift on August 22, 2016; removal of the Yme mobile offshore production unit for Repsol.[8]

Allseas has committed to building an even larger version of the same design, Amazing Grace, which is scheduled to be delivered in 2023.[9]

History[edit]

Allseas was founded in January 1985 by Edward Heerema, son of the late Pieter Schelte Heerema, founder of the Dutch offshore construction and installation company Heerema Marine Contractors. Offices subsequently opened in The Hague (the Netherlands) and Châtel-Saint-Denis (Switzerland).

The company spent its early days developing the concept of dynamically positioned (DP) subsea pipelay. The former bulk carrier "Natalie Bolten" was acquired in 1985 and converted for DP pipelay at the Boele shipyard in Bolnes, the Netherlands. The vessel was christened Lorelay in Rotterdam on 26 April 1986.[10] Lorelay immediately entered service and successfully executed her first pipelay contract, the 8-inch, 1.8-km Helder A-B pipeline, for Unocal in the Dutch sector of the North Sea.

In 1987 the company first declared its intention to build a vessel capable of lifting entire offshore platforms. The initial idea was based on two rigidly-connected, self-propelled supertankers, with a large slot at the bows to install platform topsides in one piece.[11]

During the late 1980s and early1990s the company established itself a major player in the North Sea and Gulf of Mexico. In 1992 the company acquired the former bulkhead carrier "Trenchwood" for conversion to Solitaire, the world's largest pipelay vessel. The contract for the conversion was awarded on a lump sum basis to Sembawang Shipyards in Singapore; however, due to ongoing problems the contract was terminated in 1995. The ship was subsequently converted at the Swan Hunter yard on Tyneside, England.[12] Solitaire laid her first pipe on Statoil's Europipe project in 1999.[13] Allseas and SembCorp reached a settlement for the Solitaire arbitration in 2006.[14]

In 2002 Allseas added the shallow water pipelay and construction barge Tog Mor to its fleet. In 2005 Solitaire's S-lay capacity was increased to a holding force of 1,050 t, enabling her to lay the heaviest pipelines in unprecedented water depths.[15] The same year, Allseas launched the dynamically positioned support vessel Calamity Jane. The 225 m long dynamically positioned pipelay vessel Audacia became operational two years later.[16]

Controversy

In 2007 Allseas announced plans to build "Pieter Schelte", a twin-hulled platform installation / decommissioning and pipelay vessel, named after the offshore pioneer Pieter Schelte Heerema, father of Allseas’ owner and founder Edward Heerema. At 382 m long and 124 m wide the vessel would be the largest ever built.

However, the original name created a controversy due to Pieter Schelte Heerema's service in the Waffen-SS during World War II.[17] After the war, Pieter Schelte Heerema was arrested and sentenced to jail for three years for his ties with the Nazi war effort, according to the Dutch National Institute for War Documentation.

The choice to name the ship after a Nazi SS member provoked an outcry from some politicians and Jewish groups around the world.[18] The Dutch government gave Allseas' Netherlands subsidiary a $1 million tax break for its part in designing the ship, which added to the controversy. In February 2015 Allseas stated that the name would change to "Pioneering Spirit".[19]

Victims of £73 m fraud
During a criminal trial in the UK in 2016, it was revealed that Allseas were victims of an elaborate scam in which a group of conmen fleeced the company out of £73 m.[20] In 2011 the company handed over £73 m to investors led by Luis Nobre claiming to have links to the Vatican and Spanish nobility.[21] Nobre, with his gang, led by Marek Rejniak, was introduced to Allseas as an "A1" trader with links to the US Federal Reserve and access to "lucrative" trading through a platform connected to the Vatican.

Fellowship[edit]

In April 2016 Edward Heerema was made a Fellow Chartered Engineer by the Royal Netherlands Society of Engineers (KIVI) for his pioneering and innovative contributions to the offshore and marine industry.[22] It is the first time that this title has been awarded in the Netherlands.
