Silent Bulb

Name: Silent Bulb
Brand: Damen Marine Components (Van der Velden)

Rudder-mounted propeller bulb that improves the wake field, increases thrust and reduces cavitation; fuel savings up to 1.5%, for full-spade rudders on vessels from 14 knots.

Description

The Silent Bulb from Damen Marine Components is an energy saving device mounted on the rudder on the propeller centreline. It reduces flow losses from the propeller, increasing thrust at high loads and reducing the risk of cavitation on the rudder.

Key features

Fuel savings up to 1.5%; amortisation under 1 year
Increased thrust at high loads; reduced cavitation and noise; longer rudder life
Optional Rudder Fins mounted on the bulb to further reduce propeller flow losses
Suitable for all full-spade rudder types, newbuild and retrofit

Applications

Seagoing vessels with full-spade or semi-spade rudders, speeds of 14 knots upwards, large propeller hubs and high thrust loads.

OMEGA Reinforced Laser Plate Banks for Cargo Hold Heating

Structurally reinforced stainless laser-plate heat-exchanger banks that replace failing pipe coils in barge and tanker cargo holds — built to survive sloshing loads in part-filled tanks while heating crude oil, caustic soda and other cargoes.

Equipment

Alfa Laval

OceanGlide

Alfa Laval OceanGlide fluidic air lubrication system creates an even, controllable air layer across a ship's flat bottom to cut hull friction and propulsion power; fuel savings up to 10% reported on M/V Tharsis.

Equipment
