MetalCraft Marine’s 10 Meter Interceptor model is a formidable workboat. Defined by the sum of its myriad parts, it really can be seen that ‘the equipment makes the boat.’ This month, we ask "What's in Your workboat?"In a business where there is rarely any shortage of pretty boats, cutting edge designs and equally impressively performing workboat tonnage, it is also true that the real value to any design is cemented by the very equipment that makes it run. Typically, however, comparing apples to apples when it comes to selecting your next patrol, fire, SAR or pilot boat is almost impossible. Until now.Kick the tires. Pop open the hood. Put this one up on the jacks. Spend a little time under the chassis.

Build it and they will come mentality serves TOTE well on ‘world first’ LNG ContainershipsAs the marine industry collectively struggles to find solutions to the mounting mandates to cut emissions, U.S. owner TOTE, which broke ground three years ago with the world’s first LNG-fueled containership, has more than 36 months experience operating almost exclusively on LNG. To date it has been a rousing success.As environmental mandates for ships continue to get stricter, particularly…

The sulfur emission control areas (SECAs) in place in North-America and Northern Europe, in combination with the upcoming global 0.5% limit on sulfur in 2020 (or 2025) and similar EU limits in 2020, call for alternative fuels as a means for compliance. Several alternative fuels are available and, at the same time, new fuel oil products with very low sulfur content have been introduced.In this respect, the ability of the new MAN ME-LGIP engine to run on LPG, which is a sulfur-free fuel…

Hartmann Reederei, the German ship-management company, has confirmed that two of its vessels – the 36,000 m3 LEG (liquefied ethylene gas) carriers Gaschem Beluga and Gaschem Orca – powered by the world’s first ME-GIE (-Gas Injection Ethane) two-stroke engines have collectively accumulated 10,000 hours of operations since entering operation at the end of 2017.The carriers were ordered by Hartmann and Ocean Yield of Norway, and constructed at Sinopacific Offshore Engineering (SOE)…

The world’s first liquefied natural gas (LNG) fueled bulk carrier, the 50,000 dwt newbuild Ilshin Green Iris, is powered by state-of-the-art technology from MAN Diesel & Turbo. The groundbreaking vessel, delivered in February 2018 for owner Ilshin Logistics, was constructed by South Korean shipbuilder Hyundai Mipo Dockyard (HMD) as part of a project announced in July 2016 to develop the first in a new generation of environmentally-friendly LNG-fueled bulk carriers. A single MAN B&W 6G50ME-GI two-stroke engine powers the 191-meter bulk carrier…

Mercury Marine was in New York City earlier this year offering test drives for select engines and control systems. While in town, John C. Pfeifer, President - Mercury Marine, sat down with Maritime Reporter & Engineering News to discuss marine technology development that is driving his company further, faster into emerging commercial growth opportunities globally. Barreling down the Hudson River at nearly 80 mph in a 39-ft. Cigarette boat powered by four 350-hp Mercury Marine Verado outboard engines tends to leave an impression. More impressive?

Wärtsilä and China State Shipbuilding Corporation (CSSC) have signed an agreement to establish a joint venture, which will take over Wärtsilä’s 2-stroke engine business. Through the agreement, CSSC will own 70% of the business through its affiliate CSSC Investment and Development Co. Ltd, while Wärtsilä will hold a 30% ownership position. The parties will co-operate in 2-stroke engine technology, marketing, sales, and service activities. The parties have agreed to transfer CSSC’s whole position as shareholder to a joint venture established by an entity connected with the Municipal Government of Shanghai and CSSC. Responsibility for servicing Wärtsilä’s 2-stroke engines will remain with Wärtsilä Services through its global network to support customers in a more dedicated and efficient way.

Wärtsilä and China State Shipbuilding Corporation announced the establishment of a joint venture, which will take over Wärtsilä's two-stroke engine business. Going forward, the two-stroke engine business will be reported as discontinued operations. Wärtsilä and China State Shipbuilding Corporation announced the establishment of a joint venture for manufacturing medium and large bore medium-speed diesel and dual-fuel engines. Wärtsilä estimates its profitability for 2014 (EBIT% before non-recurring items) to be around 11.5%, due to the two-stroke business transaction. Net sales are expected to grow by around 5%. Previously Wärtsilä expected its net sales to grow by 0-10% and its operational profitability (EBIT% before non-recurring items) to be around 11%.

At a major event at its Diesel Research Centre in Copenhagen today, MAN Diesel & Turbo presented its ME-GI gas engine to a 300-strong invited audience of customers, licensees and journalists. The unveiling of the two-stroke engine represents the culmination of many years’ work that began in the 1990s with the company’s prototype MC-GI dual-fuel engine. MAN Diesel & Turbo originally announced plans to carry out full-scale testing of the new engine in September 2010. Today’s successful…

Zodiac of North America, Inc., manufacturer of inflatable boats and rigid-hull inflatable boats (RIBs), announced a trade-in program for Avon and Zodiac jet-tenders in an effort to move the marketplace toward the more environmentally-friendly four-stroke models. "Our new four-stroke jet-tenders represent the latest technology, which in addition to maintaining their spirited performance, are also more in tune with today's environmentally-savvy customer," Gary Durnan, Vice President, Zodiac of North America, said. The trade-in program, Jet Set 5000, guarantees owners of Avon and Zodiac jet-tenders $5,000 for their trade to upgrade to a new four-stroke model.

Eastern seaboard operator Gypsum Transportation provided a beacon for the industry when it nominated a camshaft-less, electronically controlled Sulzer diesel engine for its 50,000-dwt-bulker newbuild project. Now, the interests behind a Mediterranean reefership scheme have also endorsed the concept, which represents a milestone in two-stroke technology, and signals a step change in large diesel engine operating flexibility. In one sense, MAN B&W stole a march on arch-rival Wärtsilä through the recent conversion at sea of a low-speed, MC-series propulsion engine to full electronic control. However, Wärtsilä's latest success in sealing contracts for two Sulzer engines configured from the outset for operation in electronic mode gives new commercial succour to the group's technological drive.

Developments in vessel powering, propulsion and related systems over the past decade, in particular, have had a fundamental bearing both on maritime technological advance as a whole, and on the ultimate efficiency and competitiveness of shipping in its manifold forms. Marine engine designers and producers devote considerable resources to driving the technology forward, marrying the client markets' ever-more pressing expectations as to economy and reliability with new environmental standards. The process demands not only a certain scale and the requisite know-how and long-term strategic vision, but also pure industrial will. Through the endeavors of MAN B&W Diesel's Danish subsidiary…

Laborde Products of Covington, La., is applying the Yanmar short stroke diesel technology to the military and light duty commercial markets. The short stroke technology allows Yanmar to provide higher rpms, which provides benefits to both water jet applications, IO applications as well as standard inboard installations. The short stoke provides the higher rpms without significantly increasing piston speed. Doug Oehrlein, Laborde Products COO, said that these benefits are being applied in a number of application. The U.S. Navy Seals, working with United States Marine, Inc, have selected Yanmar 6LY2-STP to be used in their new SOCR Riverene Craft. United States Marine, Inc., SOCR Riverene Craft powered with Yanmar 6LY2-STP supplied by Laborde Products.
