OPITO Tropical Basic Offshore Safety Induction & Emergency Training T-BOSIET for Tropical Warm Water Operating Areas

tbosiet training

The Tropical BOSIET (TBOSIET) training was originally developed jointly by the management of MEGAMAS Training Company and Brunei Shell Petroleum and is a part of the OPITO suite of Emergency Response Training Standards. It consists of the core competence and safety training requirements that are relative to all the tropical warm water operating areas of the offshore oil and gas Industry.

Tropical warm water operating areas are defined as those areas within geographical domain of the Tropic of Cancer and the Tropic of Capricorn however areas out with this domain with a consistent water temperature in excess of 15 degrees Celsius may also be included.


This training program is designed to meet the initial offshore safety and emergency response training requirements for personnel new (or returning) to the offshore oil and gas industry in a tropical environment.

  • Duration: Approx. 19 hours (3 days)
  • Validity: 4 years
  • Medical Requirement: Offshore medical certificate or medical certificate from the company
  • Pre-requisites: Nil
