Chinese Chemical Tankers To Get Clean Marine EGCS System
Clean Marine (Lysaker, Norway) has been selected by Hudong-Zhonghua Shipbuilding (Shanghai, China) to supply exhaust gas cleaning systems (EGCS) for two 38,000-deadweight-tonnage chemical tankers being built for Stolt Tankers (Buenos Aires, Argentina) and NYK Stolt Tankers (Greenwich, Connecticut).

The two vessels are built in a series of six sister ships, where the remaining four vessels will be designed with the flexibility to add an EGCS at a later stage. The order will enable these new vessels to comply with sulphur emissions legislation without switching to more expensive fuels.

For vessels operating in European or U.S. waters, inside the emission control areas (ECAs), a maximum sulphur limit of 0.1 percent will apply from January 2015. The Clean Marine system supplied to Stolt Tankers will clean both sulphur oxides (SOx) and particulate matter emissions from one engine, three auxiliary engines and three boilers. In total, a Clean Marine EGCS unit will be designed to clean 140,000 kilograms of exhaust per hour.

Installation of the EGCS unit is scheduled to take place during 2015.

GoMRI Field Campaign Examines Oil Track in Gulf
Researchers from Nova Southeastern University's (NSU) Oceanographic Center recently participated in a three-week field campaign in the Gulf of Mexico that centered on the fate of oil that is released into the environment. As part of the study, researchers took sea surface and subsurface samples.

The project is called the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE) and is funded by the Gulf of Mexico Research Initiative (GoMRI).

Research that will help predict the fate of oil that is released into the environment will in turn help inform and guide response teams. These predictions can help minimize oil spill damage to human health, the economy and the environment. Data were collected using ocean drifters that were deployed in various locations and by the release of dye to track water flow patterns.

The NSU group implemented new methods to sample the sea surface microlayer and subsurface water in order to determine what types of surfactant and oil associated bacteria were present. These bacteria can aid in the formation of sea slicks, which affect many aspects of the sea surface and can be seen in satellite imagery. Certain bacteria can also use oil as a source of energy, making these organisms important when studying the presence of oil in marine environments.

UNNC Looks to Develop Nontoxic Biofouling Solution
Researchers at The University of Nottingham Ningbo China (UNNC) are using innovative approaches to look at how surface texture can be used as a nontoxic solution to fouling.

Marine fouling occurs when organisms, including red and green algae, hydroids, scallops, mussels and encrusting organisms such as barnacles and tubeworms, attach themselves to submerged surfaces such as ships' hulls or oil rigs.

The team will test surfaces in the water at Meishan Port, a new deep-water port on the east coast of China close to where UNNC is based.

They hope that the work will lead away from chemical-based solutions that have been investigated since the international ban on the use of tributyltin (TBT).

This research reflects UNNC's focus on working to contribute to China's national priority to develop its marine economy knowledge and industry. A new £25 million International Academy for Marine Economy and Technology will foster collaborations with industry, support China's marine economy and contribute to the development of Ningbo's port.

Volstad Selects EnwaMatic Maritime Water Treatment
Volstad (Aalesund, Norway) will install 11 EnwaMatic Maritime water treatment units in two newbuilds at Bergen Group Fosen (Rissa, Norway).

EnwaMatic will provide dirt and air separation with environmentally sound water conditioning. It creates changes in key water parameters, such as pH, alkalinity and hardness to elicit corrosion inhibition, control of scale formation and a biocidal effect.

TRIAXYS Buoys to Monitor Coastal Waves of Ecuador
AXYS Technologies Inc. (Sidney, Canada) has delivered three more TRIAXYS Next Wave Directional Wave Buoys to Instituto Oceanogr'fico De La Armada (INOCAR) of Ecuador. These buoys will be added to the existing coastal wave monitoring network of TRIAXYS buoys owned by INOCAR and deployed along the Ecuador coastline. With five TRIAXYS buoys and eight Port Sentinel systems, the INOCAR coastal monitoring program is now providing real-time data from important positions throughout Ecuador.

CSA Seeks Legal Review of EPA's Vessel General Permit
The Canadian Shipowners Association (CSA) has formally sought a legal review in the United States of the implementation dates found in the Environmental Protection Agency's (EPA) Vessel General Permit (VGP), contending that the VGP imposes requirements that are currently impossible. Currently, there are two federal ballast water discharge regimes in the U.S.: one imposed by the EPA and another by the U.S. Coast Guard (USCG).

The USCG will eventually certify ballast water treatment systems for use in ships, but no systems have yet to qualify. The USCG has begun to provide extensions to affected vessels.

The CSA says the EPA has thus far declined to respond to industry's requests for parallel extensions, which has resulted in two different and conflicting federal regulatory regimes. This divergence in approach will adversely affect Canadian ship owners and their Canadian and American customers, the CSA says.

'We would like to see the EPA harmonize with the approach of the USCG and facilitate continued operations,' stated Robert Lewis-Manning, the president of the CSA.

CSA members operate Canadian-flagged and specially designed ships on Canadian coastal, Arctic and inland waters.
