Fugro Joins Barents
Metocean Project

Fugro began a three-year period of metocean and ice data acquisition as part of the Barents Sea Metocean and Ice Network Project. The data will help operators to better understand relevant operational uncertainties and risk factors in the region known as “The Far North.”

The Barents Sea represents a frontier region for oil and gas exploration. The Norwegian Petroleum Safety Authority has recognized this and in its guidance states that appropriate measures to mitigate risk should be undertaken.

Statoil is leading a joint industry project (JIP) to gather additional and necessary metocean and ice data in the region, and Fugro was contracted for the project.

In October 2015 five Fugro-manufactured Wavescan buoys, one current- and water level-monitoring mooring, and five ice thickness and current profiler moorings were deployed at offshore sites between Hammerfest and Svalbard. Real-time data are displayed on a project-specific webpage.

The final data set will be produced for the JIP partners upon completion of the measurement campaign in autumn 2018.

Multispectral Fluorometers
For Phytoplankton Survey

As part of Sir Alister Hardy Foundation for Ocean Science’s provision of rapid plankton identification capabilities and development of an integrated monitoring platform, the foundation has integrated new multispectral fluorometers on board the Continuous Plankton Recorder (CPR) for the initial determination of phytoplankton groups, supplied by Swale Technologies.

The CPR Survey samples the surface waters of the oceans with extensive spatial coverage at monthly intervals. On a number of survey routes, additional physical, chemical and biological observations of water masses are made to complement plankton data. These observations help provide environmental context for the plankton samples and are important data sets to monitor changes in the health of the world’s oceans. The JFE MFL05W-USB multifrequency fluorometers will enable simultaneous detection of several phytoplankton forms through excitation by LEDs emitting nine separate wavelengths of light. The instruments also include depth and temperature sensors and include a mechanical wiper to ensure the optical sensor window remains clean.

Projects Underway to
Tackle Marine Litter

Approximately 260 projects are planned, underway or completed as part of the Declaration of the Global Plastics Associations for Solutions on Marine Litter (Global Declaration), a public commitment by the global plastics industry to tackle plastic in the marine environment. The announcement came with the release of the plastics industry’s annual progress report, which documents the various efforts underway around the world.

The Global Declaration was launched in March 2011 at the International Marine Debris Conference by 47 plastics associations from regions across the globe. The six focus areas are: education, research, public policy, sharing best practices, plastics recycling/recovery, and plastic pellet containment.

In 2013, the Global Declaration became part of the United Nations Environment Programme’s Global Partnership on Marine Litter. To date, 65 associations in 34 countries have signed on.

Signature55 Current
Profiler to Study El Niño

Researchers at the Institute of Oceanology in Qingdao, China, are using Nortek’s Signature55 current profiler to improve understanding of El Niño and advance environmental academic research.

Data about the currents in certain areas of the Pacific are important contributions to the World Climate Research Programme project entitled “Climate and Ocean: Variability, Predictability and Change (CLIVAR)”.

These measurements can reveal low-frequency variations in the control processes of warmer waters, thus improving understanding of the El Niño—Southern Oscillation (ENSO) and East Asia monsoon seasonal forecasting.

The testing area is near the east of the Philippines in the western Pacific. Scientists will retrieve the current profiler in November.

DNV GL Honors Research
Of Young Engineers

DNV GL has honored three engineers for their scientific research with the DNV GL Award for Young Professionals, designed to find innovative ideas for increasing safety, efficiency and sustainability in shipping and to support young professionals in the maritime field.

The prize in the category “Safer” went to Aleksei Alekseev, a participant in the Erasmus Mundus Master’s program in Advanced Ship Design, jointly conducted by the universities of Rostock, Liege and Nantes. Alekseev won for his thesis “Numerical Simulation of Ice Ridge Breaking”, which created a tool to simulate the behavior of vessels operating in ridge ice. It could be expanded to model ships in various other fragmented ice formations.

Isa Duran’s paper “Total cost of ownership” won the award in the category “Smarter”. His thesis describes a synthesis software that can assess an asset’s life cycle costs at the design stage.

The award in the category “Greener” went to Victor Bolbot for his thesis “Optimization of Ship’s Bow for Added Resistance in Waves”. His work demonstrates a key trend in ship design, namely the consideration of realistic operational profiles and realistic ambient conditions. Bolbot combines simple design estimates for calm-water resistance with a semi-empirical approach for the added resistance in waves.

Sea Sentry Installed
On Bulk Carrier

CTG announced the installation of the new, improved Sea Sentry on board a major bulk carrier to monitor a newly installed SOx scrubber system. The CTG Sea Sentry monitors both the sensor inlet and outlet of wet exhaust gas scrubber systems.

To comply with International Maritime Organization (IMO) environmental regulations, global shipping must meet specific exhaust gas emission levels. One method of doing this is to clean emissions before release using an exhaust gas scrubber system. All varieties of wet scrubber systems use wash water, which must be monitored at all times to avoid discharges that may exceed regulations and damage the environment. The CTG Sea Sentry confirms that the wash water is within acceptable limits.
