Sanmar, CAT Work on Innovative Hybrid Tug

The first tug to be fitted with Caterpillar's Advanced Variable Drive, a hybrid system, is one of Sanmar’s popular and successful Bogaçay Series. It will be the 38th of this class to enter service, a class designed exclusively by RAL for Sanmar. Photo courtesy Sanmar.

Turkey’s leading tug builder Sanmar Shipyards was selected by Caterpillar Marine to build the first tug to incorporate its hydraulic hybrid propulsion system. Construction is currently under way with delivery scheduled for October 2019. Furthermore the two companies, from different continents, are joining together to present their collaborative efforts at the Tugnology 19 Conference and Exhibition, scheduled to be held in Liverpool, England, May 14-15, 2019.Tugs represent some of the more power dense and cost competitive vessels…

President Vladimir Putin calls improving the Russian navy's combat capabilities a priority.The unfinished husks of three guided-missile frigates that have languished for three years at a Baltic shipyard show that is easier said than done.Earmarked for Russia's Black Sea Fleet, the frigates fell victim to sanctions imposed by Ukraine in 2014 after Russia annexed the Crimean peninsula, prompting Kiev to ban the sale of the Ukrainian-made engines needed to propel them.With Moscow unable to quickly build replacement engines for the Admiral Grigorovich-class frigates, construction stopped.

The US Government Must Fund Icebreakers Now

Congress last funded the purchase of polar icebreakers for the U.S. Coast Guard in the early 1970s. The USCCG Polar Star (WAGB-10) was commissioned in 1976, followed by the USCGC Polar Sea (WAGB-11) in 1977. Polar Sea has been out of service since 2010 due to a major engine failure. Polar Star was ‘in commission, special’ status from 2008 through 2012 while undergoing a service life extension. It is currently the only active heavy polar icebreaker in the U.S. fleet. The less capable USCGC Healy (WAGB-20) is a medium icebreaker and is equipped to support research missions in polar waters.

The U.S. Navy's first littoral combat ship USS Freedom (LCS 1) experienced a casualty to one of its main propulsion diesel engines (MPDE) on July 11 reportedly caused by a leak from the attached seawater pump mechanical seal that resulted in seawater entering the engine lube oil system, according to the Navy. The ship’s crew addressed the leak, enabling Freedom to return to homeport July 13 on her own power for repairs on a separate, unrelated issue. While in port, the crew performed seawater contamination procedures.

Artificial Stupidity

The difference between the unmanned space missions and a similar maritime mission is fundamental. A space mission involves a large team of specialists working together for years. Assumptions are challenged and refined. Technology is pushed to the limit and beyond. Money is spent in truckloads. Tests are performed and analyzed. Triple and quadruple redundancies are built in. (the list goes on ...) Photo: NASA

There is increasing speculation regarding when the first unmanned cargo ship will set sail. The more important question is when will the first unmanned cargo ship spectacularly fail? We (not me personally, but humans as a group) have utilized artificial intelligence to launch unmanned craft into space on increasingly long and complex voyages. Mostly, these space missions succeed and provide us with wonderful images and reams of important data. Therefore, it is theoretically and practically possible to construct and operate an unmanned cargo ship.

Naval Surface Warfare Center, Port Hueneme Division's (NSWC PHD) Self Defense Test Ship (SDTS), ex-Paul F. Foster went underway for final-phase testing of two alternative fuels, May 31. The SDTS traveled to San Diego, where it took on approximately 30,000 gallons of two types of alternative fuels. The ship then proceeded on a normal cruise, demonstrating that the alternative fuels could function as a drop-in replacement, requiring no changes to equipment or operating procedures.

The USS Fort Worth, a U.S. warship that suffered damage to its combining gears in Singapore in January, will travel to San Diego under its own power for extensive repairs at a General Dynamics Corp shipyard, the U.S. Navy said Wednesday. The new coastal warship, built by Lockheed Martin Corp , will use its gas turbine engines to travel to its homeport of San Diego this summer from Singapore, where it has been deployed since December 2014, the Navy's Pacific Fleet said in a statement. The trip is expected to take about six weeks.

Competition, Quality and Demand Come Together

Silver Ships

Combat, Patrol and Law Enforcement Vessels Meet Multiple Missions with varied business plans. U.S. firms building patrol, combat and law enforcement craft are weathering government budget cuts by strengthening ties with clients and public agencies. These unique boats remain in demand because of terrorism, crime, wars, piracy and fire, and most serve multiple missions. As maritime nations beef up their defense capabilities, U.S. Foreign Military Sales (FMS) and Direct Commercial Sales (DCS) programs help builders do business overseas.

U.S. Export Reform: New Year, New Rules

Early in the coming year, the U.S. export control regime governing the shipbuilding supply chain will undergo a sea change with the implementation of export reform in the naval and marine categories of the U.S. Munitions List (USML) and the Commerce Control List (CCL). Reforms affecting the aerospace industry(1)  were published April 16, 2013(2)  and took effect October 15 of this year, and the final rules published on July 8, 2013 for the naval and marine categories will take effect on January 6, 2014. As previously reported,(3)  one of the goals of the export reform initiative is to protect the nation’s “crown jewels” with higher export control walls while removing restrictions on less important items and technologies in order to promote, among other things, interoperability of U.S.

Incat's dual fuel fast ferry has commenced sea trials in Hobart Tasmania. The 99-meter vessel's twin LNG tanks were loaded with LNG for the first time last week. Testing of the gas system went underway with the GE LM2500 gas turbine engines being run on gas for the first time on May 27 at the wharf and at sea on May 30. The gas trials are scheduled to continue. Lopez Mena (Incat hull 069) was sea trialed with ballast for a 1,460-ton displacement trial comfortably exceeding 50 knots at full power and maintaining a steady 49 knots at 90% power while operating on marine distillate.

Portable Oil Analysis Instruments

Testing oil with the Q1000 and the Q3000

The United States Naval Ship (USNS) Watson is one of the large, medium-speed, roll-on, roll-off (LMSR) ships that have significantly expanded the nation’s sealift capacity. The Watson has a considerable amount of machinery including main engines, generators and cranes that need oil tested on a regular basis to detect potential problems and eliminate the possibility of a catastrophic failure. The test kits used in the past were time-consuming and their accuracy was questionable. The (USNS) Watson is operated by Ocean Shipholdings, Inc. (OSI) under contract to Military Sealift Command.

US Navy Seeks to Transform Gas Turbine Technology

Naval Research Laboritory (NRL) scientists study the complex physics of Rotating Detonation Engines (RDE's). With its strong dependence on gas-turbine engines for propulsion, the U.S. Navy is always looking for ways to improve the fuel consumption of these engines. At the Naval Research Laboratory (NRL), scientists are studying the complex physics of Rotating Detonation Engines (RDEs) which offer the potential for high dollar savings by way of reduced fuel consumption in gas-turbine engines, explains Dr. Kazhikathra Kailasanath, who heads NRL's Laboratories for Computational Physics and Fluid Dynamics. Many Navy aircraft use gas-turbine engines for propulsion, with the Navy's gas-turbine engines being fundamentally similar to engines used in commercial airplanes.
