Marine "Black Boxes" to the

Forefront

Recorder is designed to meet the requirements of IMO Resolution A.861(20) and provides a record of shipboard infor- mation which can be retrieved in the case of a maritime acci- dent. The infor- mation is collect- ed from a variety of onboard sen- sors and written as data on two

Optical disks.

One disk can be exchanged on a regular basis to provide the shipowner with archived logs of vessel movements, while the second is housed in a sealed capsule, designed to withstand deepwater submer- sion and fire while maintaining data integrity.

MAN B&W Exchange Service

Ensures Smooth Sailing

To help owners maintain tight sailing schedules in the face of reduced engine room staff, MAN B&W has introduced an

Exchange Service designed to smooth reg- ular service of the company's L16/24 engines. Exchange Service is based on the replacement of used units during a major overhaul with renovated units. The replaced units are simply returned in the same packages as those used to transport the renovated unit, helping to minimize onboard work. In principle, all parts of the engine are addressed by the concept, but the following components are purpose- designed to benefit: cylinder units (includ- ing the complete cylinder head, piston, liner, connecting rod and fuel injection valve); turbocharger; injection pumps, HT and LT cooling water pumps; and lubricat- ing oil pump.

PropacRudder Arrangement Improves

Efficiency 5%

The new PropacRudder from Wartsila NSD is touted as being five percent more efficient.

A new product from Wartsila NSD is the PropacRudder, a so-called semi-balanced horn rudder, whose main char- acteristic is a streamlined torpedo bolted to the rudder horn. The streamlined torpedo is designed to ensure a more homogenous water flow both in front of the pro- peller and in the propeller slipstream, which reportedly gives an increased operational efficiency of five to 10 per- cent. The better efficiency offers many obvious advan- tages, including the ability to operate a vessel at same speed but at lower engine output, helping to reduce emis- sions and fuel costs. The PropacRudder can benefit many arrangements, according to its maker, but the greatest gain will reportedly be seen on full-bodied sin- gle-screw vessels.
