HamiltonJet reports that four HT900 waterjets were selected by Incat

Crowther’s latest project, a fi rst-of-type 70m Catamaran Fast Crew Boat for op- erations in the Caspian Sea oil industry in Azerbaijan. When completed later this year, the vessel reportedly will be the world’s largest high speed crew boat.

The new 70m, DP2 class vessel class will feature four control stations, each using Hamilton Jet’s MECS control sys- tem integrating with a DNV DYNPOS-

AUTR dynamic positioning system.

Powered by four 2880kW MTU engines each turning 900mm diameter waterjets, expected top speed is 36 knots with an effi cient service speed of 30 knots at full load and 90% MCR. The vessel will be capable of carrying 150 passengers and 14 crew, along with 200 tons of deck cargo, in up to 40 knot wind and seas of 3m signifi cant wave height. The vessel is under construction at the Incat Tasma- nia shipyard, with the design by Incat

Crowther and production engineering by Revolution Design. In designing this new 70m vessel class, Incat Crowther drew on its previous experience with the

SEACOR CrewZer class of fast catama- ran crewboats, with the fourth of these recently launched in the U.S. These ves- sels use HamiltonJet waterjet propulsion (quad HM811s). Prior to this vessel, the largest vessel HamiltonJet waterjets were used in was the 68.5m Gulf Craft- built crew boat Ms Netty. Designed by

Incat Crowther, it uses quad HT900 wa- terjets and has a top speed of 32 knots.

HT900s for High Speed Crew Boat

Rexroth added a new member to its product family of modular remote control systems: A lean control for controllable pitch propellers (CPP) based on the proven Marex OS platform. More than 10,000 units installed on vessels all over the world attest to the maturity and reliability of

Rexroth’s Marex OS as a hardware and software platform for controlling ship propulsion systems.

Its applications range from simple reversing gear systems to redundant controllable pitch propeller systems, for example on offshore supply vessels.

The latest system, Marex OS II-CPP, completes the modular Marex product range, closing the gap between Marex SB for small boats and Mar- ex OS for more extensive applications.

With this package, a manufacturer-indepen- dent control is now available for controllable pitch propellers in small- and medium-scale ap- plications.

Marex OS II-CPP meets all the demands of a state-of-the-art electronic remote control. The system is easily customized to the individual requirements of drive and control stations using the service and parameterization tool ParaEdit.

With this tool, customers can quickly and eas- ily specify the desired number of keys or special control head setups. The display and user inter- face options on the central unit guarantee simple commissioning.

All parameters can be set directly without the need for extra equipment.

Carnival Selects MAN Power

MAN Diesel & Turbo has won an order from Miami-based

Carnival Cruise Lines to supply fi ve medium-speed 48/60CR engines to power its next-generation diesel-electric propulsion cruise liner to be built by Fincantieri.

With a gross tonnage of about 133,500 tons and a passenger capacity of about 5,000, the ship will be the largest vessel in the Carnival Cruise Lines’ fl eet. Its construction represents the introduction of a new class of ship that will be powered by fi ve MAN Tier-II-type engines – 2 × 14V48/60CR + 3 × 8L48/60CR types – capable of delivering 62,400 kW. The ves- sel is scheduled for delivery in the spring of 2016.
