GE Delivers First Gas Turbine Module for USS Santa Barbara

GE Marine announced it has delivered its first new lightweight LM2500 composite gas turbine module to Mobile, Ala. shipbuilder Austal USA for the future USS Santa Barbara (LCS 32).GE is supplying 38 LM2500 gas turbines to Austal USA for LCS Independence variants up to LCS 38. Like all the Austal USA-built LCS, the future USS Santa Barbara will be powered by two GE LM2500 gas turbines arranged in a combined diesel and gas turbine configuration with two diesel engines.This new module, which was fully certified by the U.S.

Fairbanks Morse Power for USS Cleveland (LCS 31)

Fairbanks Morse received a purchase order from Lockheed Martin – the U.S. Navy’s prime contractor on Littoral Combat Ship’s (LCS) Freedom variant – to build and deliver the main propulsion diesel engines (MPDE's) for the 16th ship of the class, USS Cleveland (LCS-31).USS Cleveland (LCS 31) will receive a pair of 16-cylinder FM Colt-Pielstick PA6B Sequentially Turbo Charged (STC) diesel engines; together providing more than 12 MW of propulsion power. The USS Cleveland (LCS 31) will rely on the Fairbanks Morse engines for its low speed cruising and mid-range speed propulsion demands.

Future Ship Fuels: Cut through the Smoke

Ship owners increasingly face complex investment decisions as they try to navigate the most efficient course to the low-carbon future. Ever since the IMO set the industry’s ambitious emission-reduction targets for 2030 and 2050, owners have been inundated with information about future fuels and technologies that may, or may not, ultimately lower the carbon footprints of their fleet.Some of the new technologies hold promise, but the day-to-day viability of too many of them remains unproven; the same can be said for many of the potential fuels.

GE Marine Turbines Power USS CINCINNATI

GE Marine’s LM2500 gas turbines now power the Littoral Combat Ship (LCS) USS CINCINNATI (LCS 20), which was commissioned into the United States Navy’s fleet on October 5 in Gulfport, Mississippi. “GE’s skilled and diverse workforce built the LM2500 marine gas turbines used to power this sophisticated surface combatant at GE Aviation’s manufacturing facility in Evendale, Ohio, a few minutes-drive from downtown Cincinnati,” said GE’s Kris Shepherd, Vice President, General Manager, Marine Operations.

"Green" Ammonia's Future as a Marine Fuel

Ammonia, the same pungent solution used in fertilizers and cleaning agents, may one day be the key to transporting renewable energy around the world. There are currently a number of government and corporate projects assessing the feasibility of converting excess renewable energy from sources like wind, solar, tidal and nuclear into ammonia and then back into usable energy.In its purist form, ammonia or NH3 is composed of one nitrogen and three hydrogen atoms making it an ideal candidate to chemically bind excess renewable energy.

MTU Gensets for UK Navy Ships

Rolls-Royce is to supply 18 MTU Series 4000 diesel generator sets to BAE Systems as part of the Power Improvement Project (PIP) to increase the resilience of the power and propulsion system in all six Type 45 destroyers. The two existing diesel gensets are to be replaced by three MTU gensets per vessel. The three MTU gensets will complement two existing Rolls-Royce WR21 gas turbines also supplying power to the electric propulsion system.Jon Pearson, Warship Support Director, BAE Systems…

First RENK AED Drive Passes Sea Tests

Noted German gear-maker Renk reports that its new propulsion system Advanced Electric Drive (AED) was successful in its recent sea test onboard a 110-m megayacht built in the Netherlands. The megayacht was the first to feature the AED, a innovative propulsion system that is designed to be light, compact with a very low noise signature.The RENK AED was chosen when the owner eschewed traditional diesel units for the 3500-ton displacement vessel. Renk is long-experienced in the area of the electrification of propulsion systems…

For the monitoring of gas turbines: the new acceleration and pressure sensors, plus fitting charge amplifiers from Kistler (Photo: Kistler)

World’s First High Temperature Accelerometer Unveiled

Kistler has introduced what it says is world’s first high temperature accelerometer for the monitoring of gas turbines. Designed for long-term use at up to 700° C, the piezoelectric sensor – made in Switzerland – is not pyroelectric and does not show any popcorn effect, offering manufacturers and operators of gas turbines new options for monitoring the combustion stability.The efficient and secure operation of gas turbines relies upon stable combustion processes. These have to comply with increasingly strict regulations, including flexible operation on different fuels and minimal emissions.
