Common Themes/ Considerations

• Failure of working systems • Risks are constantly changing • Human error (1,000 personnel) • Production is extremely quick

(20 months) • Sea Trials in congested waters

24

Common Adjusting Issues Arising

• Restoration vs replacement • Cost effective repairs (Use of a repair yard?) • Cost presentation – labour / yard costs • Claims Control / Co-operation • WELCAR sub-limits

• Tests, Leak and/or Damage Search Costs • Expediting Costs

25

Working in Korea

• Shipbuilding Nation • Local survey expertise • Cultural sensitivities • Commercial considerations – the ‘Chaebol’ • Local Insurers’ Relationships • Local retentions

26

Summary

• There is demand for new MODU • S. Korea still main market • Construction is highly automated / controlled • Some claims arise (modest compared to value?) • S. Korea is unique
