The Shipping company will draw a planning document which will be submitted to the recognised classification society for approval.
The essential data provided in the plan are:
- Necessary ship information and particulars
- Main structural plans including information regarding the use of high tensile steels (HTS)
- Arrangement Plan of holds and tanks
- List of holds and tanks with information on use, protection, and condition of the coating
- Requirements for the survey (e.g., data regarding hold and tank cleaning, gas freeing, ventilation, lighting, etc.)
- Provisions and methods for access to structures
- Equipment for survey
- Appointing the holds, tanks and other areas for the close-up survey
- Appointing of sections for thickness measurement
- Appointing of tanks for tank testing.
- Damage experience related to the ship in question.
Annex:
It has 2 Annexes
Annex A: Guidelines on enhance survey programme of inspection during survey of bulk carrier.
Annex B: Guidelines on enhance survey programme of inspection during survey of oil tankers.
Annex A has 2 parts:
Part A: Single Skin
Part B: Double skin construction
Annex B has 2 parts:
- Part A: oil tankers with double Hull Tankers
- Part B: Oil tankers other than double hull
Each Part A & B has 9 chapters which are almost similar. The only dissimilarities being operational and constructional aspects of both type of vessels i.e. oil tankers and bulk carriers
The chapters
Chapter 1: General application, describes the application and documentation onboard to be completed prior to the inspection
Chapter 2: Renewal Survey.
Chapter 3: Annual Survey
Chapter 4: Intermediate Survey
Chapter 5: Preparation of Survey
Chapter 6: Documentation on board.
Chapter 7: Procedure for thickness measurement
Chapter 8: Acceptance criteria
Chapter 9: Reporting and evaluation of survey
For double hull tanker
1.1.1 The Code applys to all self-propelled double-hull oil tankers of 500 gross tonnage and above.
1.1.2 The Code shall apply to surveys of hull structure and piping systems in way of cargo tanks, pump-rooms, cofferdams, pipe tunnels, void spaces within the cargo area and all ballast tanks.
1.1.3 The Code contains the minimum extent of examination, thickness measurements and tank testing. The survey shall be extended when substantial corrosion and/or structural defects are found and include additional close-up survey when necessary.
During renewal survey the followings are checked for double hull tanker
During renewal survey the followings are checked for double hull tanker
