Sanmar Orders 42 Rolls-Royce Thrusters
Rolls-Royce said it has secured an extensive supply order from long-time collaborator Sanmar Shipyards for propulsion and deck equipment for tugboats the Turkish shipyard is building for various customers. The scope of supply includes 42 Rolls-Royce US 205/255 azimuth thrusters for 21 harbor/terminal/escort tugs in the 60-, 70- and 80-metric-ton bollard-pull range and high-pressure hydraulic towing winched for the 80-metric-ton models. All vessels are based on new designs developed by Canadian naval architects Robert Allan Ltd., exclusively for Sanmar.
A New Breed of Tug
When markets expand niches are created, goes the logic. For builders of tugs, that market is “floating gas” and the expanding use of liquefied natural gas, or LNG, as a fuel. In support of LNG, there’ll be more oceangoing tug duty — the new floating storage and regasification units, or FSRUs, mean busier LNG carriers, and LNG cargo owners have an interest in tug escorts that share their “carbon footprint”. Still, new emissions rules offer ways to keep using refinery products, and the work of master tug designers suggests the new breeds of tugs are about more than fuel.
Marine Fuels: Unmasking Gas
A primer on the way forward for alternative fuels for marine propulsion. By now, many of us have been passed by a garbage truck, taken a ride on an airport bus or hailed a taxi cab that is clearly labeled by their respective marketing departments that these vehicles are powered by clean burning natural gas. Even now in our own maritime industry, some trendy operators are looking to make the case for liquefied natural gas (LNG) propulsion systems, others are opting for hybrid-electric solutions, and some are even aiming for full electric configurations.
Third Dual-fuel Tug for Østensjø Rederi

Rolls-Royce, Svitzer Trial Remote Controlled Tug Operations
Earlier this year in Copenhagen Harbor, the 28-meter-long tug Svitzer Hermod berthed alongside the quay, undocked, turned 360 degrees and sailed back to Svitzer headquarters before docking again, all under remote operation while the captain was stationed quayside at the vessel’s remote base at Svitzer HQ. Though a captain and crew remained on board throughout to ensure safe operation in the event of a system failure, the remotely controlled maneuvers demonstrated a “world first” for a commercial vessel, according to project partners Rolls-Royce and global towage operator Svitzer.

LNG: Lagging, Not Gone
Low energy prices, depressed day rates and slow growth of bunkering infrastructure has dampened progress for the marine industry’s ‘white knight’ of environmentally friendly fuels. LNG, nevertheless, is here to stay. Liquified Natural Gas (LNG) is a clean fuel in abundant supply. The green advantages of LNG are well known: Class Society DNV-GL, a pioneer in the commercialization of LNG fueling for maritime applications, offers that use of LNG fuel provides “the complete removal of SOX and particle PM emissions and a reduction of NOX emission of up to 85 percent ...
