Six Thrusters Launched from


Six Thrustmaster 5,000 hp (3,700 kW)

Azimuth DP3 Thrust- ers classed by ABS were launched on

November 25, 2013 during the OOS

Gretha naming ceremony. The Brazil bound semi- submersible drilling rig was built at its ship yard in

Yantai, China by CIMC Raffl es and is due to work for Petrobras offshore. CIMC Raffl es said it is the fi rst asymmetric semisubmersible unit without brac- ing in the world. This reduces the towing resistance and dynamic positioning load, improving self pro- pelled transit speed from an average 8 knots to more than 12 knots. The asymmetric pontoon outline, with pneumatic de-ballast system, also aids quick ballast adjustment, to suit heavy lifting operation.

MTU Diesel Engines to Power

Singapore’s New Naval Fleet

Tognum announced that its MTU Series 4000 diesel engines have been chosen by Singapore Technolo- gies Marine Ltd. to power eight Littoral Mission Ves- sels for the Republic of Singapore Navy (RSN). The

Littoral Mission Vessels will be installed with state of the art, high effi ciency MTU 20V 4000 M93L die- sel engines, known for their low consumption and long service life, with each unit producing 4,300 kW (5,766 bhp), Tognum said. MTU Series 4000 diesel engines offer unrivalled power density in terms of volume-to power ratio and power-to-weight ratio.

Pushbutton Propulsion Order


PMC introduced its next generation com- pact pushbutton style engine order telegraph, the Series 8202-4000.

The 7.5-in. (192 mm) high x 5.7-in. (144 mm) wide telegraph unit features nine pro- pulsion order buttons per shaft. Other new features include iso- lated output connec- tion to the ship’s VDR, redundant communication networks and setup / alarm viewing via LCD display.

Twin Disc Propulsion

Packages to ADSB

Nico International, a Twin Disc distributor in the

Middle East, signed a contract with Abu Dhabi Ship

Building to supply and commission 30 complete propulsion packages for 15-m patrol boats under construction for Mozambique Navy. Nico said it will supply an entire range of Twin Disc products - Twin Disc Quickshift Marine Transmissions, Arne- son Surface Drives, Rolla propellers complete with

Twin Disc Control System and BCS Trim Tabs mak- ing this the single largest order for Twin Disc from this region. These carbon fi ber boats are designed to achieve target speeds exceeding 50 knots and fol- low fi rst series of 12 boats that are currently in UAE

Coast Guard service.

Noise Insulation Product Range

Halyard extended its range of noise insulation products with the introduc- tion of Rockwool

Marine Firebatt 2000. Aimed at the commercial marine sector, the multi- purpose Marine Firebatt 2000 is a rock mineral wool slab, providing fi re protection, thermal insulation and signifi cant noise reduction to marine craft and offshore installations. Marine Firebatt 2000 has been designed to meet stringent requirements for fi re protection and insulation on commercial vessels. It is rated noncom- bustible in accordance with IMO A799 and is Lloyd’s

Register of Shipping and MED (Marine Equipment

Directive) certifi ed, providing A30 and A60 fi re pro- tection to steel decks and bulkheads.

Dyena Acceleration Recorders

Scorpion Ribs is a leading boat maker, and its

Scorpion Sting can also provide proof of the ride quality and performance courtesy of data obtained using the Dyena Acceleration Recorder. The Dyena

Acceleration Recorder (DaccR) is proving to be a valuable tool for the development and comparison of fast boats. Traditionally, most boat operators have relied upon subjective comparison to evaluate the differences between vessels.

Kappel Propeller Retrofi t for Tanker

MAN Diesel & Turbo’s PrimeServ retrofi t team signed an agreement with Great Eastern

Shipping Company (GESCO) of Mumbai, India regarding a propeller retrofi t upgrade for their M/T Jag Lavanya – a Samsung-built 105,000 DWT crude oil carrier from 2004.

MAN Diesel & Turbo announced a strategic focus that added the Kappel design to its fi xed-pitch propeller portfolio, both for newbuildings and as a retrofi t solution to vessels already in service. After a decade’s cooperation with inventor J.J. Kappel, MAN Diesel & Turbo took over the Kappel design business in 2012 and has since developed it further in terms of fi xed-pitch propellers. The fuel savings and performance characteristics for controllable-pitch propellers, featuring the unique Kappel blade design, have been well documented over the last fi ve years.

Retrofi t calculations on different fi xed-pitch propellers evaluated for the M/T Jag La- vanya show the superiority of the Kappel design. Christian Wollerup Sørensen, Sales

Manager, MAN Diesel & Turbo said, “With this vessel’s speed and operating profi le, the new Kappel propeller will deliver a fuel saving of 4% together with a reduced level of pressure impulses to hull – and without adding any other, effi ciency-improving devices.”

The four-bladed, 6.9 meter Kappel propeller for the Jag Lavanya will be delivered from

China in January 2014.
