HaNSa tECH-HUB PPG MARINE Energy effcient with silicone coatings The shipping industry faces a significant challenge in achieving the iMo’s targets for carbon emission reductions, requiring major adaptations in the way new ships are designed and existing ones are operated. The ability to achieve savings of this magnitude will require new fuels, new vessel designs and radical improvements in operating effciency. in the area of low friction coatings, several studies have concluded that silicone technology stands out versus antifouling technologies, as it can significantly decrease hull drag resistance. The reason is its combination of low surface free energy and high elasticity – it has the lowest critical surface tension of any engineered material. according to PPG, as a result of these properties, silicone coatings are smoother and can deliver a significant benefit over antifouling coatings, optimizing the vessel design parameters by shifting the speed and power curves. The company performed several studies in cooperation with leading independent marine institutes in Europe, in order to measure the power and speed impact on vessels retrofitted with PPG’s Sigmaglide 1290 silicone coating. Using computational fluid dynamics analysis (CFd) following ittC standards, on different ship model geometries and hull forms, a significant shift in the speed and power curves was confirmed. The measured improvement in power demand averaged at 7% less power for the same speeds across the different ship models, says ariana Psomas, Global Segment director, Marine Newbuilding and dry docking, PPG. additional studies including mathematical extrapolations and practical validation with ships in service, confirmed the improvement in speed and power curves, which can provide a significant benefit for shipowners wishing to improve energy effciency performance. according to the company, the impressive results with PPG Sigmaglide 1290 silicone technology are attributed to the choice of the appropriate polysiloxane precursors and cross-linkers which result in the highest known silicone density of any coating on the market today. The higher the silicone density, the lower the surface energy and therefore the lower the frictional resistance and the higher the foul release properties. as a result, shipowners wishing to improve their EEdi (Energy Effciency design index) and EEXi (Energy Effciency Ship index) performance will benefit from significant reduction in power demand as well as improved operational performance and minimal speed loss. HEADWAY TECHNOLOGY OceanGuard obtained DNV GL AiP certificate oceanGuard, a Marine lNG Fuel Gas Supply System (FGSS) from Headway, has offcially received the approval in Principle (aiP) certificate issued by dNV Gl. The certification scope of the aiP includes comprehensive solutions for medium-pressure, high-pressure, and BoG compressor systems. With strict review and technical observations, dNV Gl confirmed that the system can be granted with the aiP certificate as it has fully met the international Maritime organization (iMo) iGF rules and dNV Gl requirements. according to Headway, the system can detect its working status at any time to ensure the redundancy, reliability, and safety of the security system. Meanwhile, Headway integrated the function of gas recovery, which can prevent natural gas leakage when it approaches the extreme load changes of high-pressure main engine. in the future, Headway intends to construct a shore-based real-time data monitoring platform based on the upcoming intelligent fleet management system. 56 HaNSa – international Maritime Journal 01 | 2021

HaNSa tECH-HUB SONARDYNE Sensors for robotic ships Sonardyne technology has been selected to support the world’s largest fleet of ocean-going, multi-role robotic vessels, which is being launched by marine robotics company ocean infinity. Sonardyne’s systems will provide part of ocean infinity’s new armada fleet with key sensor technologies for underwater platform navigation, tracking, control and communications, as well as ensuring uninterrupted surface navigation, even when global navigation satellite system (GNSS) services are degraded or denied. The robotic fleet that can be launched from any shoreline on the globe was unveiled in February 2020, and will initially see 17 bespoke stateof-the-art uncrewed vessels added to ocean infinity’s existing robotic fleet. The ships, initially measuring 21 m and 36 m in length, will be able to perform offshore data acquisition and intervention in both shallow and deep water operating regions. The vessels will use a range of underwater platforms, including remotely deploying autonomous underwater vehicles (aUVs) and remotely operated vehicles (roVs). The delivery of the Sonardyne equipment started in 2020. SAAB Combat system for patrol vessels Saab has signed a contract with German shipbuilding company lürssen and received an order to provide and integrate the combat system for the Bulgarian Navy’s new Multipurpose Modular Patrol Vessels (MMPV). lürssen is the prime contractor to the Bulgarian Ministry of defence, and will build the vessels at the Bulgarian shipyard MtG dolphin JSC. The newbuildings are scheduled for delivery between 2025 and 2026. Saab will carry out the work at its premises in Sweden, denmark, australia and South africa. »We are proud to continue our successful cooperation with lürssen. We look forward to contributing to strengthen Bulgaria’s defence and national security for years to come with our proven technology and solid naval combat system expertise«, says anders Carp, deputy CEo of Saab and head of business area Surveillance. MAN ENERGY SOLUTIONS SCR solution for German cruiser MaN PrimeServ augsburg, the after sales division of MaN, has developed an SCr solution that will be retrofitted aboard the cruise ship »amadea«, chartered by Phoenix reisen and managed by BSM Cruise Services. also known as »traumschiff«, »amadea« is well-known in Germany as the main filming set for a very popular television series. The retrofit devised by MaN PrimeServ augsburg calls for the integration of two of MaN’s SCr systems, one of each into both of the ship’s fourstroke MaN 7l58/64 propulsion engines. The installation will begin in September 2021. HEMPEL New antifoulings launched Coatings manufacturer Hempel has enhanced its olympic+ and oceanic+ antifouling range and has launched five new antifouling solutions: oceanic Protect+, oceanic Flex+, olympic Protect+, olympic Flex+ and olympic Protect. according to the company, olympic Protect, olympic Protect+ (for medium to high activity levels) and olympic Flex+ (for low activity levels) are based on ion-exchange technology and give protection for up to 25 idle days and up to 60-months service interval. oceanic Protect+ and oceanic Flex+ are based on zinc carboxylate technology and protect for up to 30 idle days and 60-months service interval. • Drahtseile • Tauwerk • Festmacher • CASAR Bordkranseile • Anschlagmittel • Prüflasttest bis 1.000 t • Segelmacherei • Taklerei • Montage Walter Hering KG Porgesring 25 22113 Hamburg Telefon: 040 – 73 61 72 -0 eMail: info@seil-hering.de www.seil-hering.de HaNSa – international Maritime Journal 01 | 2021 57
