ABB Offers Compact Pod

ABB launched the Compact Azipod to cover the power range from 400 kW to 5 MW. The product is designed to meet the demand for enhanced maneuverability and operational economy in smaller vessels. It is a pod- ded propulsion system providing either unlimited, 360 degree or limited, + 100 degree steering angles. It incor- porates permanent magnet synchronous motors with a FP propeller that is directly mounted on the motor shaft.

COREX Chosen For RoRo

COREX panels, an innovation from MacGregor, was cho- sen for installation aboard two 692-ft. (211-m) 30,000 gt

Stena RoRo ferries on order at Hyundai Heavy Industries (HHI). This was the first order for COREX panels, and the product was chosen because of its impact on reducing weight and reduced thickness compared to conventional car decks. The low profile and low weight of the COREX panels allow new design concepts to be adopted, helping to improve RoRo ship profitability and flexibility. COREX car decks have substantially reduced profiles, approxi- mately one-third the depth, and are about half the weight.

The advantages includ reduced lightship weight, reduced molded depth and increased stability. In the COREX panel, a 3-D truss-core is built up between top and bottom steel plates. The symmetric construction allows an even load distribution in all directions.

No Smoking Allowed

The dilemma facing the marine diesel engine manufactur- ^ JJfTj^^^^j^^^ I ••• ing industry today is as complex as it has ever faced. ^•^^HL^^HT^^^fQHKa^^k^^

Through a forest of demands from shipowners and legisla- P^^^IB^^hL^wi^^^ '^H&^Bfefl tors, diesel engine makers are being challenged to produce power plants, which perform to a broad spectrum of quali- g^^H^^^^HMyTln ^Mkmi ty levels, which are seemingly at odds with one another. ^^^^H^H^^^^huHB

The demand for better reliability, lower fuel consumption '^^^Hj •••SSS"'" ^L-1 | and better NOx and SOx emission values are the industry Hf^^^^H JHH|' ^jjfcrfj norm. Now, engine makers are challenged to produce pow- f^ja^M^^fi • « I erplants that significantly reduce Particulate Matter, or, K effectively, create little to no smoke. While all major ^^^^^^^^HJj^^^^HpKprM engine manufacturers are individually addressing this prob- . ^^M^ lem and producing solutions, MAN B&W recently unveiled its progress on the development of an invisible I smoke engine, a top priority for all engine makers given I the heightened environmental legislation which exists today. Starting with its L/V 48/60, MAN B&W has com- 14V 48/60 -14,700 kW for Star Cruises, mitted significant effort and monetary resources to develop engines which operate with invisible smoke exhaust gas, thus allowing for cruising in environmentally sensitive regions with stringent environmental regulations. MAN B&W in 1998 introduced a smoke reduction package for cruise operators travelling in the Arctic Seas of Alaska, and was in effect the first step to the IS (invisible smoke) engine LA/ 48/60. IS engines are based on two engine-linked subsystems: Fuel Water Emulsification (FWE), that requires only a moderate amount of water; and Low-load, electrically driven auxiliary blower operating at only very low engine loads. This equipment is supplemented by a matched engine setting, with regard to special tur- bocharger specification, MAN B&W turbochargers featuring Jet-Assist, low-load bypass, soot suppressing injec- tion and matched injection timing. The FWE avoids the need for a second injection system and its drawbacks, and helps to improve the opacity of smoke, particularly at low levels. Circle 54 on Reader Service Card
