The cross Installer is one of the Nobiskrug - shipyard in Rendsburg -built diving support vessel. The ship took off as Seabex One . The current owner is Kreuz Subsea Technologies in Singapore .
history
The ship was built in 1980/1981 for the Rendsburg-based company Seabex. The keel was laid on October 1st, 1980, the launch on March 1st, 1981. The ship was completed on June 18, 1981.
The Seabex One has been renamed several times. In addition, there were several fundamental renovations, including an extension and widening in 1995.
description
The ship was originally 104 meters long and 21 meters wide. It was measured with 8,300 GRT and 2,490 NRT and had a carrying capacity of 2,100 tdw. The ship started sailing under the German flag (call sign: DJTK). In the meantime (as of 7/2016) it is running as a cross installer under the flag of the Bahamas .
The ship was rebuilt in 1995 and extended to 129 meters and widened to 24.6 meters in width. It has a 1,700 m² working deck that can be loaded with 10 t / m², as well as a helipad on which large transport helicopters can land.
The ship originally had a crane on the port side and a stern boom . Four extinguishing monitors for fire fighting were installed on the rear boom . The pumps for supplying the extinguishing monitors were driven by gas turbines . Later the crane and the stern boom were removed and the ship was equipped with new lifting tools. A Hydralift with 155/34 t lifting capacity and a reach of 26 m as well as a Liebherr crane with 70/20 t lifting capacity and 25 m reach are located on the starboard side of the ship. Both cranes can move loads up to 300 m depth. On the other side of the ship there is a small 5-ton crane.
The ship has a diesel-electric drive . Five diesel generators from Krupp- MaK (type: 8M 332 AK) with an output of 1,290 kW each are installed to generate electricity . It is driven by two Pleuger propeller gondolas each in the bow and stern area of the ship. The propeller pods are driven by electric motors with 1,100 kW each in the bow and 1,620 kW in the stern area. Originally, the ship still had two transverse thruster control systems with 600 kW each in the bow area. When the ship was converted, these were replaced by a transverse thruster control system in the bow and stern area, each with an output of 590 kW. In addition, another propeller pod was installed in the stern area, which is driven by an electric motor with an output of 1,550 kW.
On board the ship there is space for 98 people who can be accommodated in 50 cabins. In an emergency, the ship can accommodate up to 500 people.
use
The main task of the ship includes diving operations and underwater welding on oil platforms. These can be carried out up to a depth of 450 m. In order to avoid constant decompression for the divers, there is a self-contained system on board in which the divers live at the same pressure as on the seabed. They reach their place of use via a diving capsule that is lowered by the moon pool in the middle of the ship. In addition, the ship helps with fire-fighting and evacuations. Thanks to the rudder propeller drives, the ship can hold its position without anchoring in almost any weather. This is particularly important when using the diving capsule.
The ship can stay at sea continuously for up to 36 days.
Trivia
In 1983 Graupner Modellbau launched a model of the ship in 1:75 scale, which corresponds to the state of construction of the Seabex One. This has, true to the original, four rudder propellers, a fully functional crane and four fire monitors at the stern.
Others
Another diving support ship based on the same design was built by Nobiskrug in 1981/1982. The Norwegian company Stolt-Nielsen was the client for the ship, which was built under construction number 710. The ship started sailing as a Seaway Condor ( IMO No. 8111879). This ship was converted into a pipe and cable lay in 1984 and scrapped in Aliaga in 2018 .
