MAIB Investigation Report

Saetta / Conger published 25 March 2010

Key issues:

  • Collision between two vessels on completion of a ship to ship transfer operation
  • Lack of operational procedures to react to on board emergencies with two vessels manoeuvring in very close proximity
  • Engine failure required STS superintendent to try and manoeuvre two vessels simultaneously
  • Poor internal and external communication led to a delay in effective avoiding action being taken
  • The potential for a superintendent to suffer the effects of fatigue and the need for hours of rest monitoring by the service provider
  • OCIMF and ICS are expanding industry guidance to include operational standards for STS service providers and advice on risk assessments and manning requirements
