Why the course?
• Hatch covers looks like simple big heavy steel plates/pieces placed on cargo hold.
• However, they are relatively large and complex pieces of engineering
• Small errors or defects can have very damaging effects, far beyond what our everyday experience would lead us to understand.

wetting damages to cargo due to leaking hatch covers
• Case study • Typical wetting damage • Investigation • Conclusion of the direct cause
• The safety barriers

Chapter 2: Hatch Covers and their function • We look in to the different key
parts connected to hatch covers
• What is the purpose?
• As example: • Is the purpose of cleats to tight the
hatch covers to increase compression; or
• to prevent the hatch covers lift from their position?
• Look into different types of hatch covers

• Understand the different testing methods and how they are performed
• As example: • With ultrasonic testing compression of sealing • With water hose testing leakage

Chapter 5: Responsibilities of master, company, laws and regulations
• When leakages occur, it is easy to blame the weather conditions.
• However, one will often find that there is evidence of both:
• bad weather; and • poor condition of hatch
cover tightness systems. • SOLAS, Load Line, MLC,
Legislation of Safe Working Practice etc.

Chapter 6: Underlaying cause to water ingress • We go back to the case study described in
chapter 1. • In chapter 1 we concluded the direct causes of
water ingress. • In this chapter we will look into the underlying
cause to the water ingress
