Wärtsilä Engines for Tallinn-Helsinki Ferry
The new, fast ropax ferry ordered by Tallink Grupp (Tallinn, Estonia) for its Tallinn-Helsinki route will feature Wärtsilä (Helsinki, Finland) dual-fuel engines running primarily on LNG.

The ship will comply with the International Maritime Organization’s (IMO) sulphur emissions legislation effective January 2015. The Baltic Sea is designated as a Sulphur Emissions Control Area (SECA).

When operating in gas mode, the sulphur oxide and particle emissions from the Wärtsilä DF engines are negligible at almost zero percent. The nitrogen oxide emissions are at least 85 percent below those specified in the current IMO regulations, and carbon dioxide emissions are some 25 percent less than those of a conventional marine engine running on diesel fuel.

The full scope of supply includes three 12-cylinder Wärtsilä 50DF and two six-cylinder Wärtsilä 50DF main engines, as well as two Wärtsilä fixed-pitch propellers and propeller shaft lines.

4D Data System For Sabertooth AUV
For offshore operators, a 4D geospatial data acquisition system with data visualization in real time is now available for the Seaeye Sabertooth AUV by Saab Seaeye (Fareham, England). This advanced system has been configured for the Sabertooth by QPS (Banbury, England). Operators get a complete hydrographic data acquisition, navigation and processing software package that is fully integrated into the Sabertooth.

The development unifies the QINSy and Fledermaus systems developed by QPS into a single enhanced option for the Sabertooth.

QINSy is a data interface and acquisition software package that consolidates data acquired from different sensors in real time. All acquired data can be viewed in various dedicated displays, which is ideal for real-time QA/QC of the data. Fledermaus analyzes and provides 4D visualization of the acquired data, such as synchronized video, water column analysis, multibeam sonars and pipe detection sensors.

Three operational modes are possible: autonomous roaming, attached fiber-optic cable, and umbilical for power and communications.

Fitted with the advanced Saab Seaeye iCON intelligent control system, its behavior-based architecture offers a decision-making capability that can, in survey mode, react to unexpected data by deviating from a programmed mission to gather data or perform a task before resuming its mission plan.

The Sabertooth can be left at deep and distant locations to operate from a remote subsea docking station, ready to be launched on routine inspection, repair and maintenance work and deal with emergencies.

Subsea UK, RGU Partner for Scottish MATE ROV Challenge
More aspiring young engineers will get the chance to participate in an international competition to design underwater machinery and robotics thanks to leadership and support from Subsea UK. The body, which represents the £9 billion subsea industry in the U.K., has entered into a long-term partnership with Robert Gordon University (RGU) to sustain and extend the highly successful Scottish MATE ROV Challenge.

The major STEM initiative aims to inspire future engineers through hands-on experience of designing ROVs used underwater in the oil and gas, defense, oceanology and marine renewables industries.

The annual event, which is coordinated by the Marine Advanced Technology Education (MATE) Center in California in partnership with RGU, involves teams made up of pupils from schools across Scotland. To date, MATE ROV has worked with 460 pupils from 29 schools, with an annual commitment from BP (London, England) and ad-hoc support from other oil and gas companies.

Subsea company ROVOP (Aberdeen, Scotland) has also stepped in to support the initiative, which, along with the financial contribution of Subsea UK and another new sponsor, brings a much needed £16,000 to the program.

The event gives students the chance to work on ROVs and provide solutions to subsea conundrums. The skills required to tackle the work are designed to promote an interest and understanding in science, technology, engineering and math (STEM) subjects.

The winners of the Scottish competition, scheduled for April 2 at RGU, will go forward to the international final to pit their wits against qualifiers from 24 other regions around the world at The Marine Institute in St. John’s, Newfoundland, Canada.

MacArtney, Sea-Bird Deliver Oceanographic Instrumentation
MacArtney Underwater Technology (Esbjerg, Denmark) and Sea-Bird Scientific (Bellevue, Washington) have joined forces to deliver four complete oceanographic instrumentation solutions to research vessel operators in Turkey, combining MacArtney CORMAC Q winches and Sea-Bird Scientific CTDs and water sampling systems.

Clients have opted to mix and match a multitude of different instrumentation options, including the broad range of optical and water quality sensors from WET Labs and Satlantic offered by Sea-Bird.

McGill Robotics Integrates Micron Sonar for AUV
The acoustic design team at McGill Robotics of McGill University in Montreal, Canada, chose to incorporate a Tritech (San Diego, California) Micron mechanical scanning sonar into their newbuild AUV. The team plans to integrate the Micron sonar into their software system in order to assist close-range positioning and detect objects in low-visibility environments. The team has also updated their AUV with new thrusters and is carrying out modifications to the frame and the pressure vessels. The Tritech Micron sonar is the smallest digital chirp sonar in the world and is part of Tritech’s SeaKing range of mechanical imaging sonars. With a 75-meter range, it offers exceptional clarity and resolution in miniature form, making it ideal for use by AUVs.

McGill Robotics hosts annual competitions.
