Presence of Anti-Fouling Paint Technology 

18 August, Thursday - Selangor 1 Room - 1:35pm - 2:05pm

Bio of Speaker


Full Name :  Yoshiro Matsubara
Title / Position:  General Manager
Company name :  NKM Coatings Co., Ltd.

Yoshiro Matsubara received Degree of Bachelor in Science and engineering departments applied chemistry from WASEDA University in 1985.
From 1985 to 2001, I worked for NOF CORPORATION as Coatings Technical Division member.
From 2001 to present, I have worked for NKM Coatings Co., Ltd.
NKM is involved in developing marine paint field with a superior type of anti-rust and anti-fouling type of hydrolyzed paint.

Energy conservation technology for ships has been considering in various fields.
For example, improvements of energy efficiency of main engine, hull structures to optimize those wave resistance may be included.
In order to exert the maximum potential of such leading-edge technologies for the energy saving, anti-fouling technologies to prevent increase of the friction resistance by fouling organisms are clearly essential.
This time, I would like to talk about reduction of friction resistance as a theme, introduce some data, and think about presence of Anti-fouling paint..

Eco-Friendly Wet Abrasive Blast

Name:  Hidehisa Ashida
Title / Position:  Technical Advisor
Company:  KM MATERIALS Co., Ltd.

1980: Graduated in theoretical chemistry course of faculty of Science and Engineering at Saga University.
1981~: Engaged in the design of the accommodation space and hull paint/corrosion protection of the merchant ships in shipyards.
2015: Joined to KM MATERIALS Co., Ltd.

NACE: Member of TG 392, TG461, TG475
Established “SP0508-2010, Methods of Validating Equivalence to ISO 8502-9 on Measurement of the Levels of Soluble Salts”

IMO: Attended meetings (MSC, MEPC, BLG etc.) under JG’s or NACE’s hat making the decision of PSPC and BWMS (G9) as SOLAS regulation.

ISO: Attended meetings under JG’s hat making the decision of the SSM standard, and established “ISO 16145-4:2013 Ships and marine technology — Protective coatings and inspection method — Part 4: Automated measuring method for the total amount of water-soluble salts”
In Japan, end-users and also some regulations require higher performance of corrosion protection for steel structure, which leads other requirement, likely higher grade surface preparation such as dry blast suitable for high performance materials.
However, it is not so easy to carry out the dry abrasive blast for high grade surface preparation at open space according to the requirement of regulations and/or agreement between factory and local community to avoid health problem for worker, prevent scattering of the health hazardous substance and the dust/smoke inside and outside the factory.
As for the countermeasure, "high pressure water treatment" and "dry-blast using media covered with sponge" are considered by ship-yard. But, they are not becoming popular because they still have many problems such as cleaning performance, anchor pattern, work efficiency (long work period and higher cost), cost for disposal of dust and etc.
And “conventional wet abrasive blast” also has some kind of problems plus quick turning for normal method and treatment of health hazardous substance for popular corrosion inhibitor.
Under these condition, we found the new type wet abrasive blast which used “magnetite powder: not listed any effluent control in Japan” for delaying of rust back, not inhibitor.
This system is very simple wet abrasive blast adopting “compressed air: 0.7MPa or more”, “fresh water” and “premixed abrasive cleaning agent: consist of magnetite powder and abrasive cleaning agent suitable for wet blast such as copper slag”.
After adoption of standard method including fresh water washing for rinsing and air blow for drying-up, “magnetite powder” will remain on the steel surface sparsely as a micro sacrificial anode to solve a week point of conventional wet abrasive blast.
We believe that this ecological and economical method will give many advantages to blasting company and their workers, shipyards and their neighborhood and end-users.

Bio of Speaker


Name: Mr Hiroshi (Dave) Iwamoto
Title / Position:  Counselling Staff, Corporate Planning
Company: Japan Marine United Corporation

Hiroshi Iwamoto or Dave, entered Ishikawajima-Harima Heavy Industries Co., Ltd. (IHI) a Japanese heavy industries company in 1969 and since has been engaged in shipbuilding industry all along.
From 1989 to 1997 he worked in London, and later in 2002 transferred to IHI Marine United Inc. (IHIMU) then established, and while serving as the company’s General Manager of Contract Administrations, and other positions, was engaged in industry related work assuming positions at The Shipbuilders’ Association of Japan (SAJ). When IHIMU merged with Universal Shipbuilding Corporation in 2013, he was transferred to this company Japan Marine United Corporation (JMU) and continues his work.
After assuming chairman of International Sub-Committee of SAJ etc., he became the chairman of Committee for Expertise of Shipbuilding Specifics (CESS) organized by shipbuilding associations of Japan, Europe, China, Korean and USA to voice shipbuilders’ opinions towards related industries.
Continuing key positions within SAJ and CESS and participating in various cross industry discussions, he became the Secretary General of Active Shipbuilding Experts’ Federation (ASEF), with members from China, Sri Lanka, India, Indonesia, Japan, Korea, Malaysia, Thailand and Vietnam, established in November, 2015, and aiming to obtain consultative status of IMO in the coming years.​​
  • ​​What is happenening?
  • What are the problems/challenges?
  • What should the shipbuilders do?
  • What are the issues related to NACE?

Shipbuilders have historically been focusing on growth that would socially contribute greatly to the economy, and was also the opportunity to become competitive, leading to larger profits.
Large scale projects were no doubt attractive, but with the development of production technology that contributed to productivity increase, cheap labour cost became less important.  Increase in capacity continued to affect the balance between supply and demand creating overcapacity and pessimism in the market, thus making the shipping industry less attractive for investments.
Under such situation, the shipbuilders need to review their strategy to focus on different ways of seeking better business environment by focusing more on technology, which relates to customer satisfaction thereby being able to offer more solutions for the ship owners who are more seeking technological advantage in their business and thus more reliant on shipbuilders’ contributions.
Coatings are becoming more and more important in dealing with regulatory matters and the shipbuilding industry is in need of more knowledge of the coating experts.
