New generation liftboat approaching completionVessel & ROV News // September 2, 2005
Kayd's capabilities will exceed even those of Myrtle, shown here.
A new generation liftboat with capabilities that will exceed existing craft is due to be delivered later this year, reports Bollinger Shipyards in the US.
The order for the new liftboat - to be named Kayd by owner Montco Offshore - follows the success of the 245ft class liftboat Myrtle, which was delivered two years ago by Bollinger Shipyards in the US to Montco.
Kayd will be a still more impressive vessel than Myrtle, the main difference between the two vessels being the cranes and their increased lifting capacity.
In a statement, Bollinger said the three cranes, all to be manufactured by Titan Industries, will include a port bow-mounted primary crane with a 110ft lattice boom rated for 175 tons; a starboard bow telescoping auxiliary crane rated for 40 tons with a boom that extends from 50ft to 70ft; and a 70ft box boom crane mounted on the starboard stern rated for 25 tons, allowing support vessels to offload personnel, cargo, and/or fluids without hindering other work being done by the liftboat.
Equipped with 245ft legs, the self-propelled floating platform will have the ability to work in water depths to 180ft with a 15ft air gap while lifting a total of 950 KIPS of variable load.
Like Myrtle, Kayd will be equipped with a bow thruster and CP propellers for greater maneuverability, enabling precision placement of the huge legs with oversized pads on the ocean bottom.
With a very high level of control over the boat, Montco will also be able to avoid contact with underwater piping, can-holes, and other rig infrastructure, and maintain jacking speed and manoeuvring to hold a precise position at the same time.
Kayd will be equipped with 40ft by 16ft pads, much larger than those on other liftboats, to provide for greater bottom stability and greater deck loads. It will also be able to jack with a full pre-load.
