Jack-ups

We designed and built our first drilling jack-up in 1959, it was named the “Seashell”.
In 1977 we started the development of the successful CJ series of jack-up drilling units.

Self-elevating platforms

We designed and built the first civil construction self-elevating platforms - named Kraanvogel and Lepelaar - in 1969. Many self-elevating platforms have been built since, for a variety of activities. Most platforms are operating in coastal or sheltered waters to support offshore civil construction works.

Jack-up Units

The Mobile Production Units will primarily see service on marginal fields. As jack-up units, the MOPUs can be relocated from one field to another.We introduced the MOPUstor for the development of remote marginal oil fields. The subsea storage tank, with a capacity of 300,000 bbls, also serves as a base for the jack-up unit.

In 1997 the first MOPUstor was launched for the SIRI field, presently operated by Dong in the Danish sector of the North Sea.

Drilling Semi-submersibles

In 1975 we designed and built our first semi-submersible, then named Viking Piper but today operating as Castoro 7.

Construction Semi-submersibles

We have long been involved in the design and construction of large construction semi-submersibles; the first example being the Viking Piper in 1975. During the offshore platform construction boom, we designed the Hermod and Balder, the DB101 and the Saipem 7000 in the late 1970’s.The large offshore cranes on these units were designed by GustoMSC and licensed for construction.

Today, the Hermod has a 5,000 ton and 4,000 ton crane, the Balder a 3,000 ton and a 4,000 ton crane and the DB101 a 3,500 ton crane. A typical niche market, no additional units were built during the next decades.

Production Semi-submersibles

In 2004, together with SBM Atlantia, we developed the DeepDraft® Semi-submersible. The deep draft contributes to a superior motional behavior, enabling the use of Steel Catenary Risers (SCRs). The EPC contract for the first unit was signed by SBM Atlantia with Enterprise LLP (AVP: Atwater Valley Producers). The Independence Hub was commissioned in 2007 in the record water depth of 8,000 ft.The second DeepDraft® Semi-submersible has been delivered to Murphy Oil. The unit, named Thunder Hawk, will start operations in 2009.

Drillships

We started the development of the DP drillships in 1969, and this resulted in the construction of a number of the “Pelican” series of vessels. Even today, a few of these successful vessels are still operating offshore Brazil.

Construction Vessels

In the early 1970’s, construction vessels were often conversions. We were involved in the conversion engineering as well as the design and construction of the offshore cranes like the Challenger, ORCA and Champion with 800 ton cranes.At the end of the 1990’s and early 2000’s we recognized renewed interest in construction vessels. This resulted in the Lan Jiang, Oleg Strashnov and Hai Yang Shi You 201 design and engineering. For the last two, we also delivered the 5,000 ton and 4,000 ton cranes.
