What the Swedish scientists discovered was a unique pharmacological mode of action that works to prevent barnacle larvae from settling on ship structures by inducing hyperactivity in the barnacle larvae. Selektope®’s fouling prevention mechanism works by temporarily stimulating the cyprid larvae octopamine receptor and activating swimming behaviour. The effects of this neurological scrambling are temporary, with the larvae returning to normal functional capacity shortly after encountering the Selektope® present in the ship’s hull coating.
With an efficacy that requires just 0.1% of Selektope® in an antifouling coating’s overall constituency, this technology offers the opportunity for coatings suppliers to use just a fraction of the active substance needed to achieve comparable performance if traditional copper-based biocides are used. In fact, Selektope® is flexible enough to boost copper-based formulations, but is also powerful enough to replace copper in copper-free formulations.
Due to the powerful effects demonstrated, this first-of-its-kind coatings technology rapidly caught the attention of coatings suppliers in the early stages of its research and development. To this date, the testing of Selektope®-containing form- ulations by coatings suppliers continues to accelerate at a rapid pace, with a multitude of commercial products being launched onto the market.
The all-important green light for global market deployment was signalled in 2015 when I-Tech received EC recognition for Selektope®, enabling it to be included in anti-fouling products sold throughout the EU as of 1 January 2016, in accordance with the terms of the EU Biocidal Products Regulation. This came in addition to the already secured approvals for the use of active agent in Japan, China and South Korea.
The first commercial, Selektope®-containing coating products for use on ocean going vessels (OGVs) were launched in the market in 2016. That same
year, a 12-month trial of a tanker coated with copper-free, Selektope®-containing paint yielded fantastic performance results. This six-year 2010-built,
46,067dwt IMO II chemical and products tanker vessel Calypso, due to enter into its second year of active
service since the Selektope®-containing hull coating was applied in November 2016, is still showing extremely low development rates of added resistance on the hull. Scandinavian ship owner, Laurin Maritime, applied the coating inclusive of I-Tech’s bio- repellent technology during the ship’s first five-year survey at the Singapore yard Sembcorp.
Another Scandinavian owner, Stena RoRo signed a contract to coat the hulls of four newbuild RoPax ferries with paint that incorporates Selektope®. The delivery of the newbuild Stena RoPax ferries is scheduled for 2019/2020. They will be built at the AVIC yard in Weihai, China.
“We are honoured that a pioneer of sustainability in commercial shipping such as Stena RoRo has chosen a Selektope®- containing hull coating product for its newbuild programme. Their investment in a premium antifouling product that contains Selektope® will deliver strong antifouling performance with the additional benefit that their high-activity vessels will have the best protection from barnacle invasion.” says Philip Chaabane, CEO I-Tech AB.
I-Tech has also celebrated success with the launching of brand new products into the market this year. The increasing diversification in the range of Selektope®- containing products available to ship owners suitable for different vessel requirements demonstrates the unrivalled versatility of the antifouling ingredient. It also demonstrates a growing commitment to the technology as demand from ship owners for antifouling coatings comprising Selektope® intensifies.
SEA GRANDPRIX 880HS PLUS is the third product Chugoku Marine Paints (CMP) has launched that contains Selektope®. It joins CMP’s SEAFLO NEO CF Premium; and SEAFLO NEO-S PREMIUM Selektope® products.
The new antifouling coating is based on hydrolysing technology and can be applied to deep sea-going vessels trading worldwide in- service periods for up to 90 months. Uniquely, CMP guarantees extended static performance of up to 45 days, thanks to the barnacle-repellent boost enabled by Selektope®- combating barnacle settlement on the ship’s hull by temporarily stimulating the barnacle larvae’s swimming behaviour.
To date, marine coating products containing Selektope® have been applied to over 150 vessels including many bulk carriers.
“As demand for Selektope® soars, the number of antifouling products that contain our unique bio-repellent ingredients is expanding. This ensures that ship owners and operators have a selection of products to choose from, and confirms the flexibility and compatibility of our product with a range of different antifouling ingredients,” says Philip Chaabane, CEO I-Tech AB.
For Selektope®, the future is promising as an ingredient for marine coating that can enable superior static performance in addition to supporting the reduction of invasive species transfer and emissions by contributing to cleaner, more efficient hulls.
Port of Grenaa expands its bulk handling expertise
In close collaboration with its customers, the Port of Grenaa plays an active role within the bulk market.
The Port of Grenaa is very good at handling large bulk orders. However, that alone is not enough for the large commercial port right on the ‘nose’ of Jutland — right by the Kattegat1 in the middle of Denmark.
“Bulk cargo is always part of a bigger logistics task where many factors must come together to solve the job in an optimal way. For us here at Port of Grenaa, the most important thing is of course to get the actual cargo off the quay here in Grenaa — but we would like to play a bigger part in the overall job, whenever it seems natural,” says Theis Gisselbæk, business developer at Port of Grenaa.
The Port of Grenaa enjoys a wide range of benefits as a commercial port. The most central deep water port in Denmark is placed beneficially close to international sailing routes in the Kattegat, and a water depth of up to 11 metres are just some of the most important benefits.
“Besides the natural benefits, we construct new ones all the time. We believe that it is important to constantly develop our expertise in collaboration between the port and our customers.
“Port of Grenaa is known for being very flexible. We are a small and very dedicated organization that can adapt and comply quickly to solve current jobs.
“Furthermore, we continuously invest in the facilities that are necessary if we want to be more than just a port that can receive and ship bulk cargo. We see Port of Grenaa as being an actively contributing collaborator for customers that need to solve a more complex logistics job,” says Gisselbæk.
Significant investments in equipment, warehouses, and large base areas around the port during the last few years have broadened the range of services that the Port of Grenaa can offer its customers in the bulk segment. Warehouses and large areas of land enable the Port of Grenaa to offer storage of cargo that might need to be redistributed over a period of time.
“We want to invest time and effort in becoming even better within this field. That is why we are adding a learning process to the jobs we solve, in order to gather experience that can be used for jobs later on,” says Gisselbæk. “This happens in close dialogue with our customers who appreciate that we, as a port, actively step in and relate to the overall transport job.”
The bulk segment is part of the Port of Grenaa’s strategic plan for the development of the port’s activities, and the port has started to reap the benefits of the investments that have been made.
During the summer, Port of Grenaa has been a pivotal element in the refurbishment of 20km of railway track on Grenaabanen between Aarhus and Grenaa.
The port in Grenaa has received approximately 30,000,000 kilograms of granite body to be put on the new tracks. The granite arrived in several orders by ship from Norway, and had to be distributed from the Port of Grenaa to the building sites that the contractor had built along the 20km-long stretch that was getting new tracks.
The Port of Grenaa arranged contact with a local carrier who was in charge of the distribution of the many tonnes of granite. The vehicles then brought back surplus soil from the track refurbishment to Port of Grenaa that must stock 20,000,000 kilograms of soil for a possible later expansion of the port.
“The replacement of the tracks was performed to a very tight schedule with delivery in seven stages. For this, the flexibility of the port was important, as well as the carrier’s local knowledge which was obviously of crucial importance for the logistics to all come together,” says Gisselbæk.
The Port of Grenaa has also become newly active in the biomass market.
The company Bioman has bought two of the Port of Grenaa’s tank yards and wants to use them for, among other things, the storage of biomass for Danish biogas plants in the future. The sale of the tank yards is a consequence of the Port of Grenaa’s strategy for the coming years of development.
At the same time, Bioman will move its company headquarters to Grenaa where administration will also be housed in the future.
‘IT WILL GET EVEN BIGGER’
The biomass that comes in via the port in Grenaa is to be used as, among other things, an addition to the biogas production to boost the process and optimize the
quality of the fertilizer product that is left over after gasification.
The biggest part by far of this specific biomass is imported from other countries, and for Bioman, sending the fairly big loads by sea is an obvious solution. The two tank yards at the Port of Grenaa increase Bioman’s storage capacity by 32,000,000 kilograms spread across 18 tanks. From the port, the biomass is taken by lorry to a range of biogas plants. It is expected that 50,000,000 kilograms of biomass will come in yearly via the quay in Port of Grenaa.
“In this case, the customer has also indicated that the choice of Grenaa is due to a mix of location and our great flexibility. This proves that with a dynamic focus on the bulk area, we are onto something that can grow even bigger,” says Gisselbæk. He adds that Port of Grenaa in general sees more interesting requests regarding new bio products that fit in well with the type of cargo that is handled at Port of Grenaa otherwise.
Port of Kalundborg expands and increases draught to handle largest bulkers
The Port of Kalundborg in Denmark is the country’s biggest port for grain export. Bulk activities at the port are primarily handled by Kalundborg Bulk Terminal, owned by Schultz Shipping, which has warehouses in the port. The bulk terminal mainly handles grains, feedstuffs, wood pellets, and fertilizers.
At the moment, the Port of Kalundborg is investing in a large expansion of the port area. This month (October), work is beginning on the construction of a new 330,000m2 port area — an addition to the existing port area of approximately 800,000m2. The new port area, which will be called the New West Port, will be ready for operations in February 2019. In the new port area there will be a 500m-long quay, and the water depth will be 15 metres. The water depth of 15 metres is important, as the Port of Kalundborg is the only deep-water port at Zeeland and only one out of three ports in Denmark with such a water depth.
Bulk handling will also be one of the main business areas in the New West Port. At the moment, dry cargo vessels can call the port at a quay, where the water depth is only 12 metres. This means that the biggest dry cargo vessels now calling at the port cannot be loaded to the maximum.
This will, however, change with the new port area, with a water depth of 15 metres, and a quay length of 500 metres. This makes it possible for the port to accommodate even the largest dry cargo vessels, and they can be loaded to the maximum amount. This means that bulk will remain one of the port’s most important business areas, and Kalundborg will keep its position as the biggest port for grain export in Denmark.
The Port of Kalundborg has had tenders regarding the construction of the New West Port. Tender A — won by NCC Industry A/S is for the work on land, and Tender B — won by Wasa Dredging Ltd — covers the dredging work.
New initiatives for port equipment and maintenance from N-service ApS
N-service ApS is a Danish manufacturer of equipment used in the bulk handling market.
The company has reported on a recent delivery,ofa2.5m3 orangepeelgrab,which was manufactured with a never previously installed maintenance system.
The grab has been in full-time operation for three years, loading all types of steel scrap to vessels.
This grab, and its design, have provided optimal and constant loads. The dead weight and load capacity was designed from the outset to work with the Multidocker CH65/CH74. Unique penetrating and holding power ensure capacity and supported load and machine efficiency.
With its volume of 2.5m3, the grab has a deadweight of 3,400kg. It has been built with 90mm main bearings, which affords the longest lifetime and zero downtime for maintenance.
All connections was secured and protected from damage during work. This also ensures efficiency: the crane operator can focus fully on the bulk product, due to his complete confidence in the design of the grab.
There has been no damage to the grab in three years of operation.
The unique laminated tooth-sets have remained sharp, with a strong grab, throughout.
The revolutionary self-lubricating system was a key factor to the success of the grab. The unique hydraulic self lubrication system uses the grab’s working pressure to drive the self-lubrication grease pump. The system pressurizes grease up to 250 bar and injects grease to all main bearing and cylinder bearings —15 bearings in total.
A progressive distributor block links the grease optimally to all bearings, with regard to function and load. A pre-defined quantity of grease is released in continuous cycles, driven by the main actions of the grab. For one grab opening, one portion of grease is released.
The system is a refilling system with the usage of own preferable grease. This makes the system independent and profitable for the operator.
Lubrication and maintenance of the whole grab occurs while working and always leaves the equipment ready for the next task. Maintained and greased.
