It will be 128 m in length, have a 25 m breadth and about 9 m draught and will have a hopper volume of 11,500 cu.

Jan De Nul has ordered a heavy lift crane vessel capable of lifting 5,000 metric tons from the CMHI Haimen shipyard in China. The vessel, to be named Les Alizés and due to enter service in 2022, will be equipped with a full SCHOTTEL propulsion package, including four rudderpropellers, two retractable rudderpropellers and two transverse thrusters.The main propulsion system of the crane vessel consists of four electrically driven SCHOTTEL Rudderpropellers type SRP 610 FP – each with an input power of 3,000 kilowatts and a propeller diameter of 3.3 etersm – installed at the stern.

German propulsion manufacturer SCHOTTEL said it has been selected to equip a newly built harbor tugboat for the Saint Lawrence Seaway Development Corporation (SLSDC) with medium-sized azimuth thrusters. The vessel is under construction at the U.S. shipyard Washburn & Doughty in Maine. The HT-60, the smallest in the harbor tug series developed by the Seattle-based naval architecture firm Glosten, is scheduled for delivery in 2021.Craig Middlebrook, Deputy Administrator of the SLSDC, said, “This new vessel will be used to carry out a variety of construction and maintenance duties for the U.S.

Since its introduction to the market a mere three years ago, the SCHOTTEL azimuth Rudder EcoPeller SRE has delivered on a wide range of different applications for open sea and coastal operating conditions. In doing so, it has both shored up the ferry segment and moved far beyond it.In the ferry market, the SRE demonstrates its highly efficient and ecologically clean propulsion while also meeting the strict environmental regulations of the Norwegian market. As a result, SCHOTTEL has achieved a top market position there by providing propulsion systems for 16 ferries in various power ratings.

The presence of biofouling on the hull of a ship increases the drag from the water during sailing and thereby the fuel consumption, which results in increased CO2 emissions as well as increased costs for the ship owner. Paints applied to the underwater areas on the hull of ships therefore often contain biocides to hinder biofouling growth or possess non-stick properties, allowing a release of the fouling when the vessels pick up speed.AkzoNobel is working with Royal Philips to…

PPG’s (NYSE: PPG) protective and marine coatings business will showcase four of its’ premium marine coatings solutions at SMM event in Hamburg. Amongst these is one of PPG’s most recent product innovations, the PPG SIGMAGLIDE 1290 fouling release coating. Its 100% silicone binder fouling release system utilizes a breakthrough dynamic surface regeneration technology to eliminate slime problems and dramatically increase fuel savings compared to existing fouling release products.

What is an EAL? Environmentally Acceptable Lubricants (EALs) are defined by the EPA as offering these three characteristics. First, they must be “biodegradable” - biodegrading into carbon dioxide and water by ≥ 60% or more within 28 days (according to OECD 301B or ASTM D7373 methods). Next, they must be “minimally toxic,” causing only a light impact on the aquatic environment (LC50> 100mg/L for lubricants and LC50>1000mg/L). Lastly, they are “not bioaccumulative,” and must have a low propensity to bioaccumulate in organisms.

Low-friction, self-lubricating coatings use patented technology to deliver reduced fuel consumption and improved tolerance to idle time. PPG Protective and Marine Coatings announced the launch of SIGMA SAILADVANCE, a new range of antifoulings suitable for a variety of operating conditions. The range currently comprises four coatings, including SIGMA SAILADVANCE RX and GX, two completely new formulations based on PPG’s own patented technologies. These antifoulings are based on…

IHC Sealing Solutions has received an important third-party verification from DNV GL, a  ship and offshore classification society. This means that the company’s Supreme Ventus and Supreme Athmos seals (that guarantee zero oil emissions) are now compatible with mineral oils that are used in U.S. waters in compliance with the Vessel General Permit (VGP). On December 19, 2013, the revised VGP, issued by the U.S. Environmental Protection Agency (EPA), came into force. This new permit mandates the use of environmentally acceptable lubricants for all oil-to-water interfaces, such as stern tube and thruster seals, on all merchant vessels that are 79 feet or longer and sailing in U.S. coastal and inland waters.

There was record attendance at the Maritime Propulsion Services BV (MPS) open day on May 23 when more than 200 delegates from shipyards, classification societies and workshops around the world gathered together in Drunen. Apart from the four propellers which were in the workshop for repair, on display were some of the latest developments in quality control as well as repair procedures and technology. These included state of the art nondestructive ultrasonic techniques to inspect either for porosities in bronze castings or weld repairs on propeller blades.

Liquid photopurification specialist company SurePure Inc. apprises of a breakthrough in the microbiological purification of contaminated marine diesel fuel, using SurePure's technology as an alternative to biocide addition or excessive micro-filtration. SurePure explains that the contamination of diesel fuel is a significant problem for the maritime shipping industry, leading to extensive waste of fuel and environmental contamination. The industry is seeking to improve conventional means by which it cleans fuel where micro-organisms have proliferated. SurePure, in conjunction with a South African oil industry consultant Lemon Tree Holdings, applied its proprietary Turbulator technology in a test conducted in April at Stellenbosch, South Africa.

The proposed 2013 Vessel General Permit prompts vessel managers to review the portfolio of lubricants used on their vessels. One of the Environmental Protection Agency’s (EPA) changes in the proposed 2013 Vessel General Permit for commercial vessels over 79’ is a requirement to use environmentally acceptable lubricants in certain applications. Given this proposed change, it is a good time for vessel managers to review the portfolio of lubricants used on their vessels to look for gaps in the operational performance of the lubricants…

ROV will be used in an attempt to determine if oil is present on sunken WWII tanker. Global Diving and Salvage Inc. has been contracted by the United States Coast Guard to determine if oil is present aboard the sunken ship S.S. Montebello, which sits 900 feet below the ocean surface approximately 6.5 miles off the coast of Cambria, California. The S.S. Montebello sank after a Japanese submarine torpedoed the large oil tanker on December 23, 1941. The vessel broke apart landing upright with her bow separated from the majority of the wreckage. To date, no signs of leakage have been detected, and from previous visual inspections by submarine, the cargo section appears to be intact. The possibility of future oil release has prompted the U.S.

Physical sampling determined that no oil remains after 70 years. After 11 days of survey and sampling, using both the latest in technology and physical sampling it was determined that no oil remains on the SS Montebello. The on-scene assessment of the sunken World War II tanker S.S. Montebello is nearly complete off the coast of Cambria, CA. The unified command, led by the Coast Guard and California Department of Fish and Game's Office of Spill Prevention and Response, has determined that there is no substantial oil threat from the Montebello to the surrounding waters and shorelines.
