Innovation and new technology continue to shape the marine coatings market. A narrowing field of global coatings manufacturers offer new products while improving existing ones to meet customer demand. Ultimately, customer demand, along with environmental compliance pressures are all driving the marine coatings industry as ship owners, operators and shipyards alike seek better products. Customer demands are often related to cost and efficiency. Costs – and the list is a long one – include not just product cost…

The solution was found in Antwerp, in 2015, when ZF approached…

UNO Researchers Develop Nontoxic Technology Against Corrosion

University of New Orleans (UNO) researcher Al Daech is afraid of heights; not a good phobia to have when your research involves space shuttles, fuel tanks, and other, big, space-age equipment. He's been trying to conquer his fears since 1981. That's when his work on corrosion fighting collided with his fear of heights. As a Martin Marietta (now called Lockheed Martin) consultant, Daech found himself on a narrow bit of scaffolding 450 ft. in the air, inspecting one of the external fuel tanks on STS-I Columbia, the first space shuttle. Three days before the launch, a pool table-size blister formed in the external tank of the STS-I. Daech's inspection showed an oily rag wiped across the tank caused the blister. He and a crew immediately went to work.

Adances in Marine Coatings & Corrosion Control

The advance of modern marine coatings and related technologies is not unlike other technical sectors of the maritime industry, primarily driven by emerging regulation from the international, national and regional level, usually in regard to environmental concern. But in recent years, an increased focus on the reduction of marine emissions in tandem with the capability to more directly correlate clean, well-maintained hulls with reduced fuel consumption and lower emissions has driven the industry further faster…

TRAILBLAZERS: Ultrastrip Helps Clear the Way

While convention holds that the most vital marine technological advances happen in or around the engine room and bridge, the business of coating and corrosion control - stripping, preparing and applying - arguably poses the most strenuous test the marine environment offers. It is a vessel's initial coating and maintenance thereafter that largely determines a vessel's lifecycle, thus its profitability. Coatings, much like mechanical systems, require constant attention to ensure that they are performing the duty required, namely maintaining the structural integrity of the steel beneath. That said, the last place a vessel owner want to see its vessel is in drydock, with a battalion of workers vigorously peeling, stripping and chipping away at a vessel's armor.

London P&I Club Urges Maintenance of Hold Pipework

The London P&I Club has urged shipowners to ensure proper maintenance of cargo hold pipework in order to prevent wet damage to cargo, which has become a regular source of claims. In the latest issue of its StopLoss Bulletin, the club notes, “Leakage from pipework within holds continues to be a common cause of cargo wetting. Of particular concern are leaking top-side tank drain pipes and wells when located near or below the load water line, which can result in catastrophic hold flooding. “By way of preventative maintenance, pipes should be monitored for signs of corrosion and kept well coated.

A total of 5,300 gallons of Sherwin-Williams Protective & Marine Coatings ensures that one of Washington’s most valuable assets will provide service for years to come. With a longstanding history of ferry operation in the Puget Sound, Washington State Ferries (WSF) was in need of a coatings company with just as strong of a reputation when preserving the 3,634-ton M/V Kaleetan auto/passenger ferry in the summer of 2015. Built in 1967 in San Diego, Calif., the M/V Kaleetan – which means “arrow” in Chinook – first went into service in early 1968 and was rebuilt in 2005.

NACExpo 2003 Set for San Diego

According to the study, "Corrosion Costs and Preventive Strategies," the cost of corrosion in the U.S. is a staggering $276 billion per year. The shipping industry alone accounts for $2.7-billion, broken down into new ship construction — $1.1 billion, maintenance and repairs — $0.8 billion, and corrosion-related downtime — $0.8 billion. This study was initiated by NACE International — The Corrosion Society and mandated by the U.S. Congress in 1999 as part of the Transportation Equity Act for the 21st Century (TEA-21), and conducted by CC Technologies Laboratories, Inc, with support from the U.S. Federal Highway Administration (FHWA) and NACE. This year more than 7,000 of the world's leading corrosion professionals will meet in San Diego, Calif.

First Standards for Application of Corrosion Resistant Steels

ClassNK has developed and released the world’s first set of standards for the application of corrosion resistant steels to the cargo oil tanks of oil tankers. The new Guidelines on Corrosion Resistant Steel for COT are the first guidelines to lay out clear requirements for the application of the new steels, whose use was approved by the IMO’s Maritime Safety Committee (MSC) earlier this year. The growing volume of crude oil carried by the world’s tanker fleet has led to rising concerns over pollution of the marine environment, and the last decade has brought tremendous changes to the building and survey requirements for oil tankers.
