Germany-based corrosion specialist Steelpaint is calling for urgent action to address the significant environmental impact of steel corrosion, warning that inadequate corrosion protection is contributing more to global CO2 emissions than the entire aviation industry. With the maritime industries consuming an estimated 100 million tonnes of steel annually, premature corrosion and subsequent steel renewal work is increasing carbon emissions dramatically, said Steelpaint’s Managing Director Klaus Müller.Steel production remains one of the most carbon-intensive industrial processes.

Sourcing and maintaining marine coatings systems are arguably a shipowner’s most critical means to ensure a long and productive lifecycle for ships, boats and offshore rigs. At the same time, coatings have become a central part of the ship efficiency, decarbonization discussion. Christer Øpstad, Global R&D Director Fouling Protection, Jotun, discusses how these macro trends are driving R&D within his laboratories today.To start us off, can you provide a ‘by the numbers’ look at Jotun today?Jotun is headquartered in Sandefjord, Norway, still a family-owned company founded almost 100 years ago.

Germany-based protective coatings innovator Steelpaint GmbH is urging shipowners, shipyards, and port authorities with steel assets to prioritize surface preparation, advising that skimping on this critical step in the application process is leading to premature coating failures, costly repairs, and increased safety risks.The advisory follows a recent request to apply its single-component, moisture-cure Stelcatec to a steel structure that had not been properly prepared, with high…

Xiamen Minhua Shipping has specified a Steelpaint corrosion protection system for a trio of newbuild multi-purpose cargo ships building at Fujian Shipbuilding’s yards in China. The order marks the Germany-based coatings specialist’s first newbuilding contract with a Chinese shipowner.The first vessel in the series, the 12,000dwt Min Hua 9 delivered from the Fujian Hengsheng shipyard in June, is now operating with a Stelpant-PU-Zinc universal primer protecting steel cargo holds…

The efficacy of surface preparation and coating application in the new construction shipbuilding industry is fundamentally anchored in a well-coordinated, integrated approach. This intricate process, essential for achieving top-tier corrosion control, is methodically segmented into five crucial stages:Raw material entryPainting the modulesSmall partsPainting of erection joints at the module levelFinal paint and ship's completion. Each stage is crucial in its own right but achieves…

Corrosion and BlueStream launched ICCP-SAM, touted as sustainable corrosion protection of XX(X)L monopile foundations. ICCP-SAM is designed to remotely install ICCP anodes on monopile foundations of all sizes, anywhere on the foundation and even in the roughest ocean conditions.The ICCP-SAM (Subsea Assembly Method) is compact and can be transported and deployed with minimal resources from the topside of the offshore foundation. It is operated remotely and maneuvers the anode underwater into the designated foundation entry hole. The anode is then secured to the foundation using the same tool.

HamiltonJet has unveiled a new range of high-efficiency waterjets, starting with the LTX36 model. Optimized for medium- and low-speed operation, New Zealand-based manufacturer said it has produced the first waterjet to rival the energy efficiency and bollard pull of the best propeller-based systems between zero and 30 knots.Waterjets are among the most efficient propulsion options for going fast due to the absence of hull-appendages and their highly optimized pump geometry, but HamiltonJet CEO Ben Reed noted not everyone wants to go fast.“Our customers’ needs are changing…

HamiltonJet said its new HTX47 waterjet has improved upon its previous jet model to offer a more seamless installation experience. Its new compact inboard footprint design and fully integrated hydraulics system ensures faster installation in the vessel.HTX47 new hydrodynamic design delivers 4% more high-speed efficiency, a 16% increase in peak bollard pull, and offers better operation at minimum speed, according to the manufacturer. It also features enhanced corrosion protection for more durability and expanded impeller rating range for greater compatibility for a wider range of engines.

The largest U.S.-flagged, self propelled trailing suction hopper dredger (THSD) Frederick Paup will be propelled by a trio of Schottel RudderPropellers manufactured at the German Wismar production site. Scheduled to enter operation in 2023, the dredger will be owned and operated by Manson Construction Co., and is currently under construction at the Keppel AmFELS Shipyard in Brownsville, Texas. It will be 128 m in length, have a 25 m breadth and about 9 m draught and will have a hopper volume of 11,500 cu.

Heating, ventilation and air-conditioning (HVAC) systems keep you cool in the summer and warm in the winter. That’s the simple explanation. It does not encompass the complexities of what needs to be done to assure the all-important continued conditioning of the air in your vessel.The systems installed in vessels today can run the gamut from static vent scoops that force air into an area to a raw water chiller system whose workings take up the same amount of space as a 40-foot cargo container. The equipment is there to meet the need of the end user.

Underwater foul-release coatings company Propspeed said it has partnered with Marine Protection Systems to educate and provide solutions to prevent corrosion and minimize damage to vessels and the marine biosphere.The insulative properties of Propspeed combined with correct anode solutions greatly improve efficiencies, reducing fuel burn and operational costs, while also minimizing the environmental impact that corrosion and coating loss has on the oceans.

Surface plating is widely used to repair or salvage critical components in the marine industry. As many components need disassembly, the repair process is typically carried out when the ship is in dry dock. Due to the nature of the plating process, this work is usually performed by plating or machine shops off-site. In a quest to add value through reduced downtime and labor costs, many shipyards are looking to bring this service in-house. Mark Meyer, Sales Manager North America at SIFCO ASC…

Margins are tight for vessels that operate offshore or in coastal waters. Take the global offshore support vessel (OSV) market for example, it looks set to be yet another challenging year which has concerned senior executives preparing for a sixth year of downturn. Many had hoped that 2019 would be the year that marked a turning point in OSV fortunes, but the uptick hasn’t materialized, and there is renewed anxiety about what could potentially be the worst market since the 1980s.It…
