Since the first newbuilding application of Intersleek coatings in Korea (2005), a total of 73 vessels have been successfully coated with Intersleek products in Korean Newbuilding shipyards, including Knutsen’s 2 LNG carriers which were coated with Intersleek 1100SR and delivered from Hyundai Heavy Industries (HHI) in 2016.

Newbuilding Application Procedures

The general antifouling application procedures and stages in Korean yards are as follows:

Block Stage Hull Stage

(= Building Dock Stage)

PDD (Pre-Delivery Dry-Docking) Stage after fitting out

 

  • All antifouling coats on the flat bottom are completed at ‘Block Stage’.
  • After erection of all blocks, the Intersleek scheme is applied to join-up areas with the exception of the final coat which is applied at the ‘Hull Stage’ after the required surface preparation.
  • The final coat of antifouling for the Vertical Sides is applied at ‘Hull Stage’ shortly before launching.
  • In the case of LNG vessels (in some yards), the final coat of antifouling on the Vertical Sides can be applied during the PDD (Pre-delivery Dry-docking) Stage to provide a fresh paint film before delivery, considering the longer outfitting period (~12 months).

For Intersleek Newbuilding applications, the same 3 stages can also be used depending on the yard’s situation.  The main application procedure options can be summarized as follows:

Case #1

Intersleek application to flat bottom at Block Stage

Intersleek application to vertical sides at Hull Stage (= Building Dock Stage)

Example:

Case-1

Case #2

Intersleek application to flat bottom at Block Stage

Intersleek application to vertical sides at PDD Stage

Example:

Case-2

Case #3

Intersleek application to vertical sides only at Hull Stage (= Building Dock Stage)

Example:

Case-3

Case #4

Intersleek application to both flat bottom and vertical sides at Hull Stage (= Building Dock Stage)

Example:

Case-4

Case #5

Intersleek application to both flat bottom and vertical sides at PDD Stage

Example:

Case-5

 

Summary

The Newbuilding shipyards that have experience with Intersleek applications in Korea are Daewoo Shipbuilding & Marine Engineering, Hyundai Heavy Industries, Samsung Heavy Industries and Hyundai Mipo Dockyard.  All of them have developed their own optimized procedures in consultation with AkzoNobel.  The representative cases shown above explain all the current scenarios used in Korean yards for the application of Intersleek at Newbuilding.
