DSC Dredge and Deep Diggers Ltd announced the launch of a new 18-inch Shark Class dredge manufactured in Bangladesh.In 2019 U.S.-based cutter suction dredge manufacturer DSC Dredge signed a memorandum of understanding with Deep Diggers Ltd, Bangladesh with a project focus of providing an engineering design and component package. Deep Diggers imported all the dredge components from DSC including the Caterpillar diesel engine, dredge pump, gearbox, cutter assembly, winches, hydraulic system and lever room and controls.

As owners and operators work to achieve dramatic new emission reductions, vessels’ cooling solutions should not be overlooked.A  wave of green initiatives is sweeping through the maritime market as owners and operators seek ways to reduce emissions from their vessels. One company supporting this drive is R.W. Fernstrum, a global leader in engineering and manufacturing keel cooling technologies.Sean Fernstrum, the company’s president, sees a mix of power and propulsion solutions—each with its own list of pros and cons—combining to help reduce the industry’s environmental footprint. And R.W.

The Netherlands-based Value Maritime has received the International Air Pollution Prevention (IAPP) certificate from Lloyds for its scrubber system.A press release from the engineering and ship financing company said that most of the tests required to obtain certification had been performed during installation."Since the Value Maritime scrubber uses a new innovative technology, we had to further demonstrate its performance outside SECA in order to receive class approval," it said."To this end, the scrubber system was put to test under diverse and extreme conditions on the first vessel on which it was installed. This was undertaken while the vessel was doing its voyages between the Netherlands and Russia.

China's maritime authority has banned the discharge of "wash water" used in ships to strip hazardous sulphur emissions from engine exhaust gases from Jan. 1, in an effort to curb pollution of its coastal seas.The ban on discharges from so-called open-loop scrubbers affects all rivers and ports along China's coastline and includes the Bohai Sea, according to an official from the China's Maritime Safety Administration (MSA).The measure mirrors a similar move made in Singapore ahead of International Maritime Organization (IMO) rules that will ban ships from using marine fuels with a sulphur content of more than 0.5 percent from 2020, unless…

China's maritime authority has banned the discharge of "wash water" used in ships to strip hazardous sulphur emissions from engine exhaust gases from Jan. 1 for some ports, according to a government document reviewed by Reuters on Tuesday.The ban on water discharge from so-called open-loop scrubbers is part of an effort to prepare for International Maritime Organization (IMO) rules that will ban ships from using fuel oil with a sulphur content of more than 0.5 percent from 2020…

Exhaust Gas Cleaning Systems Association (EGCSA) has attacked Singapore's restrictions on open-loop versions of the systems as "disappointing" and "politically motivated."The scrubber manufacturing industry body said in a press release: "The recent announcement by the outgoing CEO of the Maritime and Port Authority of Singapore (MPA) banning the discharge of process water from open loop scrubbers for vessels visiting Singapore came without prior notice or discussion with the IMO despite the fact that the Singapore MPA is a signatory to MARPOL Annex VI."The MPA provided neither scientific evidence for its decision nor was the industry invited to consultationit said.

Maritech Ltd. signed a sales and distribution agreement with French water microbiology company aqua-tools to meet “significant interest” in onboard ballast water testing from Greek shipowners.The agreement, which covers the training and supply of aqua-tools’ B-QUA test kit, was inked during the Posidonia 2018 event, in early June.“Greek shipowners are looking at the use of indicative-based monitoring as a means of assessing the efficiency of their ships’ ballast water treatment systems…

The world’s first container feeder vessel refit to use natural gas was commissioned in late August in Bremerhaven, ushering in a new era in the use of alternative fuels across the global maritime sector. The container vessel Wes Amelie, owned by Wessels Reederei, Haren/Ems, was converted for the use of methane as a standard fuel at the German Dry Docks Shipyard in Bremerhaven, making it the world’s first of its kind vessel which consumes environmentally friendly methane. This conversion is more than simply another environmentally advanced ship…

The Harris Pye Engineering Group is currently engaged in turnkey scrubber installation packages for major cruise line companies. On August 3, 2016 Harris Pye completed the installation of an Advanced Emission Purification System, fully automated, which was duly DNV GL certified which met with MARPOL regulation 14 of Annex V1 for the control of emissions complying to regulations 14.1 or 14.4. The design package for open and closed loop systems was utilized to model and fabricate all piping systems, hardware integration, and major/minor steelworks. Along with new exhaust tail pipes, sea chests were installed with the vessel in service along with the associated overboard discharges.

International trade relies on transportation by sea, as about 85 percent of the freight volumes are shipped globally by vessels. But while maritime is widely regarded as the most environmentally benign of any transport system, maritime transport can cause a diverse environmental burden: It includes, beside the potential for damages and leaks, the inflow of waste water and, in particular, the emissions of air pollutants. Furthermore the improper cleaning of oil sludge, as well as the transfer of organisms into foreign ecosystems within ballast water.

Are shipowners prepared to enter SECA zones? Due to existing regulations on air exhaust emissions from the International Maritime Organization (IMO), and with the European Union working towards an alignment with IMO MARPOL Annex VI, the marine industry will need to choose a path on how to achieve compliance, a choice that will have tremendous impact on shipping. Legislation has already had an effect on the fuel markets in regulated areas, as fuel prices are expected to increase even further in 2015 when the 0.1% fuel sulfur limit enters into force.

Bosch Rexroth is accepting registration for all courses in its popular training program designed for industrial and mobile hydraulics systems engineers. Rexroth’s Hydraulics Technical Training is targeted toward individuals who maintain hydraulic systems, design new systems or want to upgrade existing systems with new technology. Rexroth provides on-site training for specific hydraulic installations, and customized training programs are available with test stands delivered to the participant’s location.

While convention holds that the most vital marine technological advances happen in or around the engine room and bridge, the business of coating and corrosion control - stripping, preparing and applying - arguably poses the most strenuous test the marine environment offers. It is a vessel's initial coating and maintenance thereafter that largely determines a vessel's lifecycle, thus its profitability. Coatings, much like mechanical systems, require constant attention to ensure that they are performing the duty required, namely maintaining the structural integrity of the steel beneath. That said, the last place a vessel owner want to see its vessel is in drydock, with a battalion of workers vigorously peeling, stripping and chipping away at a vessel's armor.
