Study Notes
Survey Planning
- Before developing a survey programme, the ship owner must complete a survey planning questionnaire.
- The questionnaire requires information on:
- Hull-related deficiencies identified during PSC inspections.
- Hull-related non-conformities issued during SMS audits.
- Cargo carried history to determine the frequency of corrosive cargoes.
- The condition of the coating as per the ship owner's inspection of ship spaces.
Damage History
- Damage history is considered when developing the survey programme.
- This includes damage history of the ship and its sister ships.
- If a particular area has suffered frequent damage, it will be subject to closer inspection during the renewal survey.
Industry Trends
- The survey programme takes into account general ship damage trends in the industry.
- This includes identifying areas of high risk, such as cracks at the midship area.
Inspection Requirements
- The survey programme outlines minimum requirements for inspecting ship's hull and structure during each type of survey.
- Structures to be inspected include:
- Cargo holds and hatch covers.
- All pipings.
- Ballast tanks.
- All hull plating.
- Watertight bulkheads.
- The programme guides on the extent of inspection (overall survey or close-up survey) for each element.
Overall Survey
- The overall survey reports the overall condition of the hull structure.
- Examples include the annual survey of cargo tanks, which requires a good visual inspection.
Close-up Survey
- A close-up survey involves a detailed visual inspection of structural components within hand reach.
- Examples include the close-up survey of cargo holds during the renewal survey.
Survey Types
- Types of surveys include:
- Annual survey.
- Intermediate survey.
- Renewal survey.
- Dry dock survey.
Enhanced Survey Programme (ESP)
- ESP is not a separate survey, but provides guidelines for inspecting hull and structure during surveys.
- Guidelines are provided in the ESP code for bulk carriers and oil tankers.
- ESP guidelines include:
- Who to inspect: two surveyors for bulk carriers of 20,000 tons deadweight and above.
- When to inspect: renewal survey may be commenced at the fourth annual survey, with completion by the fifth-anniversary date.
- How to inspect: inspection of the outside of the ship's bottom should be carried out with the ship in dry-dock for ships of 15 years and over.
This questionnaire is designed for ship owners to provide crucial information on hull deficiencies identified during inspections and non-conformities issued during audits. It also includes collecting data on the cargo carried history of the ship, particularly focusing on corrosive cargoes that could damage the coating.
