It’s European Design, But Built For The Jones Act Market

(Image: Damen)

The Netherlands-based Damen Shipyards Group is one of the industry’s largest and most recognized shipbuilders, perhaps best known for its standardized, serial production workboats. Now with several dozen newbuild and repair yards on the map, the company has produced more than 6,000 vessels over its 90-year history—from harbor tugs and offshore supply ships, to ferries and patrol craft. But Damen does not have a shipyard in the United States, and therefore doesn’t directly build vessels for the Jones Act market. Instead, it licenses its designs to U.S.

Will 2020 be the year for Subsea Mining?

Anyone who has been around the Offshore Oil and Gas or the Marine industries for long has heard of plans for mining various minerals located on or just below the seafloor. In fact, when Howard Hughes built the Glomar Explorer in 1972, the cover story for its true mission – recovering a Soviet submarine - was that the rig would be used to mine manganese nodules from the deep ocean floor. This cover story was so effective that it had the unintended consequence of stirring great interest in ocean mining among offshore companies and the general public.In the years since…

The reasons for that are many and these realities cater to regulatory, commercial and regional needs.The U.S. dredging market is complex and relies on the diverse fleet of private dredging companies to get the job done. In addition to design and technical capabilities, environmental restrictions and regulations often dictate whether a trailing suction hopper dredge, cutter suction dredge, or mechanical dredge can respond to the coastal protection, wetland restoration, port deepening, and channel maintenance needs of the Nation.

Singapore: LNG Terminal to Develop Data Center

The National University of Singapore's Faculty of Engineering (NUS), Singapore LNG Corporation (SLNG) and Keppel Data Centers Holdings join forces to develop new energy-efficient cooling technology for data centers.This innovation could further pave the way for more sustainable and compact data centers, said Singaporean conglomerate Keppel Corporation.With the rapid expansion of cloud-based services, AI, the Internet of Things and big data analytics, there has been an exponential demand across the globe for data centers in recent years. As the leading data center hub of Southeast Asia, Singapore accounted for around 50 per cent of the region's data center capacity in 2015.Due to the high internal load and the need for consistent cooling and operation in a tightly-controlled environment…

Researchers have deployed high-tech robotic sensors disguised as boulders for the first time to measure the initiation and evolution of the huge, hard-to-measure seafloor avalanches that regularly damage global networks of seafloor telecommunication cables.The so-called "smart boulders" revealed some surprising findings that will help inform where best to lay the seafloor cables that keep the internet running. Published this week in the journal Nature Communications, this research shows that submarine avalanches of rock and sand…

Marine salvage experts are floating a plan to tug icebergs from Antarctica to South Africa's drought-hit Cape Town to help solve the region's worst water shortage in a century.Salvage master Nick Sloane told Reuters he was looking for government and private investors for a scheme to guide huge chunks of ice across the ocean, chop them into a slury and melt them down into millions of liters of drinking water."We want to show that if there is no other source to solve the water crisis…

Arctic Research Explores the ‘Roomba’ Approach

The pace and quality of oil spill research in the United States typically ebbs and flows as a function of two, if not three important variables. First, after the 1989 Exxon Valdez grounding, there was a flurry of activity to ramp up oil spill research because it had been dormant for so long. The need was recognized, with plenty of money made available. Primarily, this research centered on conventional spill remediation techniques – for example, a tanker or barge spilling oil – and not much else. Predictably, when memory of the spill faded, so did interest in research and funding followed.

Warning on Hazards of Carrying Bauxite by Ship

A new warning that bauxite may become unstable when carried in bulk on a ship, potentially causing the vessel to capsize, has been issued by the International Maritime Organization (IMO). Bauxite is one of the world’s major sources of aluminium with around 100 million tonnes transported annually by sea. In 2015, a bulk carrier sank while transporting bauxite, with the loss of 18 seafarers. Research presented this week to an IMO Sub-Committee found that certain forms of bauxite with a large proportion of smaller particles could be subject to a newly-identified phenomenon of “dynamic separation” when there is excess moisture in the cargo.

Catfines: Uncertainty Must Be Addressed

Earlier this year the International Organization for Standardization (ISO) published a revised edition of its ISO 8217 specifications for marine fuels, which still maintains a 60 mg/kg limit for catfines (catalytic fines). It’s not rare to hear comments about this threshold being on the high side. A recent test conducted by the Fuel Oil Bunkering Analysis and Advisory Service (FOBAS) takes the debate to a new level. It shows that a number of bunker samples delivered in Fujeirah…

Custom Mud Cat Dredge to Improve Boise Watershed

Ellicott Dredge Technologies (EDT) informed that the City of Boise, Idaho chose it to design a Mud Cat 40E Custom (MC-40EC) dredge for the city's innovative Dixie Drain Phosphorous Offset Project. Boise will use the MC-40EC dredge to remove phosphorous from the Boise Watershed. Boise selected the MC-40EC due to Mud Cat’s global reputation for quality and their proven ability to deliver custom features. The custom features include the overall length of the dredge, the slurry pump flow and pressure, a fully protected auger system, and an auger calibrated to specific digging depths for the project. In addition to its custom features, the MC-40EC boasts several other unique systems.

Mud Cat MFD-1000 Dredges Lake for Residential Development

Ellicott Dredge Technologies (EDT) has been successful in launching a Mud Cat Multi-Function Dredge (MFD) at the SouthBay Residential Development in Bismarck, North Dakota. The dredge will remove 20,000 cubic yards (15,290 m3) of sand and clay from a private residential lake where developers are busy constructing high-end single family homes situated on 3 miles (5 km) of shoreline. Kevin Turnbow of Turnbow Construction and Home Building selected the Mud Cat MFD-1000 due to its ability to handle various materials including compacted clay and sand. It is also self-propelled with a 24 in. (610 mm) stainless steel steerable prop, so it does not require any anchor cables which would negatively impact the pristine shoreline. The MFD-1000 is pumping the slurry 900 ft. (274 m) with 24 ft.
