MMT Conducts Cable, Seabed Survey for Statnett
MMT Sweden (Västra Frölunda, Sweden) has completed a cable and seabed survey for Statnett (Oslo, Norway) at Lofoten and Rombaken, Norway, to identify the condition, position and possible burial depths of the cables.

MMT conducted the survey using the MV Stril Explorer and the work-class ROV Kystdesign Supporter. The Rombaken portion of the survey was challenging for the ROV, with almost vertical slopes on both ends of the fjord. The cable tracking system used was the ORION by Optimal Ranging (Santa Clara, California). It was the first time MMT used the system on HVAC cables, and the system showed good positioning horizontally and promising results vertically.

CalWater 2015 Studies Factors Influencing Weather
Scientists embarked on a field campaign to improve the understanding of the natural and human-caused phenomena that determine when and how the state gets its precipitation. They will study atmospheric rivers and meteorological events, including the famous rainmaker known as the Pineapple Express.

CalWater 2015 is an interagency, interdisciplinary field campaign that started in January and entails four research aircraft flying through major storms, while a ship outfitted with additional instruments cruises below. The research team includes scientists from Scripps Institution of Oceanography, the Department of Energy’s Pacific Northwest National Laboratory, NOAA and NASA, and uses resources from the Department of Energy’s Atmospheric Radiation Measurement (ARM) Climate Research Facility.

The study will help provide a better understanding of how California gets its rain and snow, how human activities are influencing precipitation, and how the new science provides potential to inform water management decisions relating to drought and flood. Researchers will examine the strength of atmospheric rivers, which produce up to 50 percent of California’s precipitation and can transport 10 to 20 times the flow of the Mississippi River. They will also explore how to predict when and where atmospheric rivers will hit land, as well as the role of ocean evaporation and how the ocean changes after a river passes.

“Improving our understanding of atmospheric rivers will help us produce better forecasts of where they will hit and when, and how much rain and snow they will deliver,” said Allen White of NOAA. “Better forecasts will give communities the environmental intelligence needed to respond to droughts and floods.”

Push for Green Shipping in Norway
Norway’s Minister of Trade and Industry Monica Mæland and State Secretary for Climate and Environment Lars Andreas Lunde signed a declaration of cooperation with key players in the Norwegian coastal shipping industry to ensure that Norway has the world’s most environmentally friendly fleet of coastal vessels. DNV GL (Høvik, Norway) has also launched a Green Coastal Shipping program, a joint effort by industry and authorities.

LNG and battery power are projected to constitute a considerable share of the global fleet’s fuel. Norway already has a leading position in this field and has a good environmental and business starting point to more broadly implement these new technologies.

“The green shift in the maritime industry will both resolve environmental challenges and create value,” says Tine Sundtoft, Norway’s Minister of Climate and Environment.

“We envisage a fleet of offshore vessels, tankers, cargo, container, bulk and passenger ships, ferries, fishing and aquaculture vessels, tugs and other coastal vessels run entirely or partly using batteries, LNG or other green fuels,” says DNV GL’s Narve Mjøs, program director for Green Coastal Shipping.

Corvette Gets EGCS To Comply With ECAs, EPA
The ECO VLGC Corvette, delivered from Hyundai Heavy Industries (Ulsan, South Korea), is fitted with a class and flag state approved exhaust gas cleaning system (EGCS) provided by Clean Marine (Lysaker, Norway). The measurements of exhaust gas emission and washwater criteria are well below the required limits stated in the MEPC guideline 184(59). This ensures vessel compliancy with the 0.1 percent sulfur limit in Emissions Control Areas (ECAs), which has been in place from January 1, 2015. The vessel is also compliant with the stricter U.S. EPA requirements of a pH above 6 in washwater, measured at the outlet. The approved EGCS will enable the new Dorian LPG (Stamford, Connecticut) vessel to comply with current and future legislation relating to sulfur emissions without switching to more expensive fuels. The Clean Marine system on board the Corvette cleans both sulfur oxides and particulate matter emissions from the main engine, three auxiliary engines and one boiler.

Horizon Gets ECA Waiver, Pursues EGCS Installation
Horizon Lines, Inc. (Anchorage, Alaska) has received a permit providing a conditional waiver from the North American Emissions Control Area (ECA) fuel sulfur content requirements of MARPOL Annex VI regulation 14.4. The permit is in force while Horizon pursues installation of an exhaust gas cleaning system (EGCS) on each of its three D7-class vessels that operate in the Alaska trade. The permit was issued by the U.S. Coast Guard and the U.S. Environmental Protection Agency and will allow these Horizon vessels to use low-sulfur, heavy fuel oil in their main engines, while operating between Washington state and Alaska. Further, Horizon has entered into a supply agreement with Alfa Laval Aalborg Nijmegen BV (Nijmegen, Netherlands) for design and procurement of the PureSOx 2.0 EGCS for the three Horizon D7-class vessels that operate in the Alaska trade. This EGCS is a multiple inlet hybrid system that will clean the exhaust gas from the main engine and the main generators, and is the first system of its kind for a Jones Act container vessel. Installation is to begin on the Horizon Kodiak in September 2015, and completion of the project is expected by December 31, 2016.
