Seas to Continue Rising Even if Climate Goals Are Met

Sea levels will rise between 0.7 and 1.2 metres (27-47 inches) in the next two centuries even if governments end the fossil fuel era as promised under the Paris climate agreement, scientists said on Tuesday. Early action to cut greenhouse gas emissions would limit the long-term rise, driven by a thaw of ice from Greenland to Antarctica that will re-draw global coastlines, a German-led team wrote in the journal Nature Communications. Sea level rise is a threat to cities from Shanghai to London, to low-lying swathes of Florida or Bangladesh, and to entire nations such as the Maldives in the Indian

The study of extreme wave events in the ocean has become a popular area of research in recent years. Aside from seafarers, extreme waves impact coastal communities and are of great interest to marine renewable energy companies. This is particularly prevalent in the face of coastal erosion, rising sea levels and uncertainty in how the wave climate will change in a warming world. However, much of the current research is based on modeling and experiments. Extreme wave events – including storm waves, rogue waves, storm surges and tsunamis – are rare, and as such are difficult to observe and

Surface currents in the upper 1 ocean are very important in driving the fate of marine debris and pollutants but are also challenging to measure. Tracking the upper ocean in an effective manner may require massive deployment of GPS tracked drifter buoys, which until now were expensive, cumbersome and quite polluting themselves (i.e. made of PVC, ABS and Nylon). The CARTHE drifter is an answer to the need for a compact, user-friendly, robust, yet eco-friendly solution. Scientists with the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE), in collaboration with the

Oceaneering Adds New Reel Drive System

Oceaneering International, Inc. has taken delivery of an 800-metric-ton SWL (Safe Working Load) reel drive system (RDS) from Maritime Developments (MDL).   The modular system will be used to deploy and retrieve SURF products (subsea umbilicals, risers and flowlines) on board the company’s new-built multi-service vessel, Ocean Evolution and joins Oceaneering’s global fleet of flex-lay equipment.   Rated for over 1,300-metric-ton DWL (Dynamic Working Load), the RDS is rated for handling 14m diameter reels weighing 800 metric tons under dynamic, sea-state conditions. The RDS

Sonar Technology to Be Used to Detect Sharks in the US

has been on the rise. Some of the predators on the western U.S. coastline can measure up to 12 feet in length, posing a threat to surfers and beachgoers.   In order to provide an early warning to the relevant authorities managing beach safety, sharks can be detected and tracked using the SMS marine monitoring system utilizes Tritech International Limited Gemini 720is multibeam sonar technology in conjunction with its SharkTec software.   Tritech’s original high-definition sonar imaging software, conventionally used in the subsea oil and gas sector, was adapted by utilizing shark

New Study Will Examine Hydrate Blockage in Subsea Jumpers

The University of Western Australia (UWA) is leading a joint industry project (JIP), supported by the Industry Technology Facilitator (ITF), to provide industry with a better understanding of the mechanism of hydrate growth and blockages.   The 12-month study, entitled ‘Hydrate Deposit Growth in Subsea Jumpers (HyJump)’, currently has the support of industry partners, including Chevron, Total and Woodside, and is welcoming more participants to join the project.   To simulate the flow geometry and risk of hydrate blockage in subsea equipment, the project will see the development

missions using survey tool Smartrak from U.K. based INNOVATUM Ltd. The company designs, manufactures and operates compact, low-powered magnetic cable and pipeline tracking systems.   INNOVATUM said recent tests have successfully demonstrated fully autonomous passive magnetic tracking of a submarine cable by AUV, using Smartrak.   INNOVATUM has released the AUV data protocol for a standard communications format between Innovatum Smartrak and AUVs. The data protocol allows operators and AUV manufacturers to prepare AUVs for cable and pipe tracking tasks. The data protocol document is available

Wison Launches Buoyant Tower Solutions with Storage

Wison Offshore & Marine has developed a new Buoyant Tower solution with condensate or oil storage, adopting Wison’s proprietary Buoyant Tower technology. This floating concept provides a new economic and reliable option for the oil and gas development in the shallow to medium-depth waters.   Originally invented by Ed Horton and Lyle Finn, the Buoyant Tower technology was first applied to BPZ CX-15 project offshore Peru when both Ed and Lyle worked for Horton Wison Deepwater Inc. (HWD), now renamed as Wison Offshore Technology Inc. with 130+ patents originated by Ed Horton and his
