Technical inquiries to SRC Group ramped up after it received Approval in Principle (AIP) for a concept which ‘reinvented methanol fuel storage’ on board ships. Delivering the answers has seen technical talk converting into project discussions        ‘Green’ methanol has the ability to one day run vessels almost emission-free, and commercial shipping increasingly investigates. Derived today principally from natural gas, methanol is nonetheless available, relatively easy to handle and predictable.

A pigment package designed by the U.S. Naval Research Laboratory (NRL) to slow discoloration of the exterior coating on surface ships has started to make its way into the fleet and is producing early, positive results.NRL researchers created the pigment combination to satisfy the fleet requirement for the Navy standard "haze gray" paint that will remain color stable for longer than current coatings. While many paint manufacturers had produced new coating technologies that solved a variety of other problems…

The chemical tankers market is projected to grow from USD 26.63 billion in 2017 to USD 33.11 billion by 2022, at a CAGR of 4.5% between 2017 and 2022, said a research report. The flourishing chemical industry and increasing use of water transportation for transferring chemicals from one place to another across the globe are the major driving factors for the growth of the chemical tankers market, said Report Linker. Chemical tankers market includes revenues earned through shipping of chemicals and related products. The growth of the chemical tankers market is expected to be adversely impacted by the political unrest in the Middle East & Africa region as this region is one of the leading markets for chemical tankers.

With more than 90 percent of global trade carried by sea, shipping is a major battleground in the reduction of emissions. Tier III is the latest emission standard pertaining to NOx emissions from marine diesel engines. Tier IV is expected to come into effect for 2020 – with engine manufacturers already seeking sealing components to future-proof engines well into the next decade. Here we explore challenges faced by diesel engine operators in the face of Tier III, and how the correct selection of sealing materials could deliver better performing solutions.

Although ship and boat building design engineers have traditionally specified parts made of rubber, plastic or steel when durability is required, many are considering cast polyurethanes as a new alternative for demanding, high-wear, abrasion and impact applications. Cast polyurethanes, also broadly referred to as urethanes, are tough, elastic materials that combine many of the performance advantages of high-tech plastics, metals and ceramics along with the resiliency and flexibility of rubber parts and are ideal for ship/boat building components.

AkzoNobel has completed the $3.5 million expansion of its U.S. research and development facilities in Houston. Carried out in phases over a period of three years, the investment in the site – which employs around 40 scientists – will support the company’s Protective Coatings, Marine Coatings and Specialty Coatings businesses. Part of AkzoNobel’s ongoing investments in its global RD&I activities, the Houston upgrade follows an investment of $ 14.2 million in a research and innovation hub in Felling, U.K., announced earlier this year.

PPG has introduced PSX 800 and PSX 805 coatings for steel and metal surfaces, two next-generation products formulated with greater flexibility and hiding performance than competing polysiloxane coatings. According to PPG, the two new products feature improved flexibility, which enables them to withstand the cracking under stress commonly associated with difficult steel, tank exterior and building exterior applications. PSX 805 coating adds a durable satin-sheen finish that masks imperfections on metal surfaces.

Debuting its latest offering at Posidonia 2016, PPG’s protective and marine coatings business has unveiled a new protective system for dry bulk carrier cargo holds: the PPG SIGMASHIELD MTC system, built on coating technology that comprises a PPG SIGMASHIELD PRIME undercoat and PPG SIGMASHIELD MTC topcoat. Designed specifically for the cargo holds of dry bulk carriers, the system’s chemistry maximizes technical performance and offers a commercially sound solution for spot and full repairs as well as for application at newbuild, PPG said.

Dry dock pontoon deck preservation is often taken for granted. In the flow of ever changing priorities for dry docks, it often gets pushed aside and/or delayed. If neglected long enough and often enough between preservation cycles, the thickness of the pontoon deck steel plates can be compromised. Salt water with chloride contamination causes accelerated corrosion while impact and abrasion damage from heavy equipment also take their toll. For shipyards, the overall objective should be to provide a protective surface that will hold up over time, and that is easy to clean.

Russian Maritime Register of Shipping (RS) has issued Certificates of approval for tank containers made of polymer composite materials (PCM) intended for transportation of aggressive media. The manufacturers of tank containers are JSC “Research and production corporation UralVagonZavod” / Uralcryomash JSC. Issuance of RS documents is a logical end of one and a half year activity of a group consisting of specialists from JSC “Research and production corporation UralVagonZavod” / Uralcryomash JSC where a series production of PCM containers is expected to be commenced, “STTC ApATech-Dubna” ltd. which is responsible for design of material and structure, Spectransgarant LLC - tank container company-operator and RS.

Marine paints manufacturer Hempel announced the launch of a new pure epoxy tank coating, Hempadur 15460, to replace its Hempadur 15400 tank coating. Hempadur 15460 is designed specifically as a tank coating for chemical vessels and is based on amine adduct cured epoxy technology, which the manufacturer says delivers resistance to continuous immersion in a range of chemicals, including crude oil up to temperatures of 80ºC/176ºF. The coating uses no toxic products and can be used to coat all liquid cargo tanks. It is also suitable for grey and black water tanks, mud and brine tanks, refrigerated seawater fish tanks and other vessel tanks.
