Royal IHC successfully named and launched the 550t pipelay vessel SEVEN CRUZEIRO at its shipyard in Krimpen aan den IJssel. This is the last pipelaying vessel in a series of three ordered by Subsea 7. Subsea 7 is extending its fleet to meet the increasing demands for offshore activities in deep waters.
The 'SEVEN CRUZEIRO' is a Pipelay and Offshore Construction Vessel. This ultra-modern pipelay vessel with a class 2 dynamic positioning system (DP-2) will be deployed to install flexible flow lines (piping) and so-called umbilicals. With a working depth up to 2,500 meter the ship offers new chances of exploiting oil and gas fields.
Huisman, located in Schiedam, will fit a 550 ton J-lay pipelaying tower. With a J-lay system, pipe stalks are upended and welded to the seagoing pipe in a near vertical ramp. The pipe leaves the lay system in an almost vertical position using the moonpool; it is only bent (once) during installation (at the seabed). This is why it is called a J-lay, as the pipe is shaped into a J. Huisman will also install a 400m Offshore Mast Crane. The vessel is fitted with two under-deck storage carousels with a capacity of 2,500t and 1,500t of pipes. The vessel will also have twin ROVs for underwater work.
The Seven Cruzeiro is the eighth ship that the Offshore Division of IHC has built for Subsea 7. Together with Huisman IHC, has built the ‘Seven Oceans’ (pipelay vessel), ‘Seven Seas’ (construction/flex-lay), ‘Seven Atlantic’ (diver support vessel), ‘Seven Pacific’ (construction/flex-lay) and ‘Seven Waves’ (heavy construction pipelayer). They also built ‘Seven Sun’ (heavy construction pipelayer), ‘Seven Rio’ (heavy construction pipelayer), and ‘Seven Cruzeiro’ (heavy construction pipelayer).
In the near future this pipelayer will be deployed for the development of oil sources near the coast of Brazil.
The Seven CRUZEIRO is also the eighth ship that the combination Croon Elektrotechniek and Bakker Sliedrecht (CCB) successfully commissioned. The combination took responsibility for the complete driving system. Croon was responsible for the low-voltage installation; this included the emergency panels, the low-voltage panels of 400 V and the 230 V panels. Bakker was responsible for supplying and installing the high-voltage systems, including the generators, high-voltage panels (6.6kV) and the trustor motors.
The Subsea ships listed above, the Seven Oceans, Seven Seas, Seven Atlantic, Seven Pacific, Seven Waves, Seven Sun and the Seven Rio, were also fitted with the installations of Croon and Bakker.
