Superyachts Yacht contracts
for Dykstra Netherlands-based designer Dykstra & Partners is currently undertaking a project to build a 40m J Class vessel – widely regarded as the 1930s version of the modern ‘superyacht’ – named Rainbow. Unlike the original design, Rainbow is being built in aluminium and designed in accordance with the JCA (J Class Association) maximum performance rules. The hull has been built
by Bloemsma
Aluminiumbouw and the yacht is currently at Holland Jachtbouw for final outfitting, with delivery scheduled for 2012. Other J Class projects under construction include
Yankee, which will feature a 325kW main engine, a 50kW generator and a 32 kW auxiliary generator, and, currently being outfitted in the Netherlands, at Balk Shipyard, is Mikhail S. Vorontsov, a 65m loa staysail schooner. Balk already had the basic, completed hull on its premises, Gil Wang, naval architect at Dykstra, told Ship & Boat International, and the yard has modified the design to adjust the sheer line of the yacht, the deck and sail plans and her exterior styling. Wang acknowledged that using an existing hull was a challenge; as the frames were already in place when Dykstra took over the project, the volume to draught ratio was restricted and the design needed to take subsequent weight factors into consideration. Dykstra is also involved in the panama ketch
project, which seeks to realise a fast, 60m loa yacht capable of transiting the Panama Canal, while retaining an elegant and traditional feel. Te hull is a high tech carbon construction, with prepreg carbon skins and a Corecell and Nomex core.Te ship has no main engine, instead utilising four smaller Volkswagen Marine TDI 350-8 engines
that deliver power to propulsion, deck equipment and electronic items as required. There are two retractable hydraulic drive thrusters and a retractable Hundested FT 4 RL 128 kW bow thruster, so as to increase the vessel’s speed when sailing. The yacht, which was christened in July 2011, is classed by Det Norske Veritas (DNV).
Tug design New contracts for
OSD Netherlands-based tug and OSV design specialist Offshore Ship Designers (OSD) has received the go ahead to design a new 44m anchor handling tug (AHT) offshore support vessel for Dutch operator Neptune Marine Service. Upon delivery, the AHT will be utilised for anchor handling, ocean towage and wind farm construction support activities. Te vessel will feature a bollard pull capacity of
70tonnes and feature accommodation for 22 persons, while the inclusion of two main propellers with nozzles and three transverse thrusters is intended to grant her DP-1 station keeping ability. At time of going to press, OSD claimed that it would deliver the detailed design of the vessel in October this year, and launch and delivery have been pencilled in for the second half of 2012. Te agreement follows closely behind a contract
awarded to OSD by Singapore’s Pacific Offshore Engineering
and Trading, which commissioned
the group to produce designs for two Azistern24/56 vessels, each featuring a length of 25.85m, a beam of 10.8m and 70tonnes bollard pull. Each of the duo will be powered by twin Cummins QSK-60 main engines and Rolls-Royce azimuthing thrusters, delivering 56tonnes bollard pull and generating a speed of 11.5knots, in addition to being equipped with Fi-Fi 1 class equipment. Construction of these two vessels commenced in May this year,
OSD’s new 44m AHT support vessel will feature a bollard pull of 70tonnes.
