The ISV Siem Moxie, an Ulstein SX 163 design not only has been deemed a “Great Ship” in our pages, it has also been awarded the “Offshore Renewables

Awards 2014” and the “Innovation Awards” by an international panel. The Siem Moxie measures 242 x 55.7 ft. (74 x 17 m). It is the very fi rst X-Bow sup- port vessel which features two sets of Voith Schneider

Propellers. Both the Voith Schneider Propellers are also used for its active roll stabilization system and dynamic positioning (DP-class 2). Its design drew on a wealth of experience within the offshore business.

Its specifi c role will be to support work crews to the platforms and foundations in order to prepare for the submarine cable pull-in and terminations. In addi- tion the vessel can also be used to support the erec- tion and maintenance of the wind turbines, which are typically installed once the installation of submarine cables has been completed. The Siem Moxie’s low fuel consumption makes it particularly environmen- tally friendly. The vessel’s key features are a 3D mo- tion-compensated knuckle boom crane and an active motion compensated personnel transfer gangway, permitting the safe transfer of work crews. Thanks to the ship’s active roll stabilization capabilities, off- shore works can continue even in challenging sea and wind conditions. “We chose the Siem Moxie because it will make our installation operations extremely safe and effi cient,” Sven Utermöhlen explains. “In addi- tion it will help make the construction of offshore wind farms more cost-effective, thereby helping this technology move closer to market maturity.” The

SIEM MOXIE is deployed on E.ON’s Amrumbank

West offshore wind farm project by Siem Offshore

Contractors for the installation of the inner array grid submarine cable system. It is the vessel’s fi rst area of operation. Amrumbank West is an offshore wind farm located north of Helgoland in the North Sea, which

E.ON has been building since January 2014. Amrum- bank West will extend over 32 square kilometres. Its 80 technologically advanced 3.6 megawatt wind tur- bines will give it a total capacity of 288 megawatts, enough to power up to 300,000 households.

Höegh Jacksonville was delivered by Daewoo-Manga- lia Heavy Industries S.A. (DMHI), the fi rst from a series of two 6,500 units Pure Car Truck Carrier (PCTC). This vessel is owned by Ocean Yield from Norway while the charterer is Höegh Autoliners AS, a leading global pro- vider of RoRo vehicle transportation services, based also in Norway.

The vessel, the biggest of her type ever built into the

Black Sea and the Mediterranean Sea area, measures 655.8 x 105.8 x 32.2 ft. (199.9 x 32.26 x 10 m), a maxi- mum speed of more than 16 knots, powered by a MAN

B&W licensed main engine rated at 8,330 kW. The ship was built under the supervision of DNV and registered in a port of NIS (Norway International Ship Register).

The vessel presented challenges in terms of welding thin plates and designing for maximum vehicle loading capac- ity in a small space. In addition to the vessel’s size, the installation of the specialized equipments for carrying the wheeled cargo was successfully fi nalized by the DMHI employees, which required high skills and delicate weld- ing. The vessel was delivered upon contractual delivery date, just 12 months after steel cutting and also the total recorded period elapsed after contract signing.
