IDESS is an independent organisation providing training services to the maritime and offshore industries. The International Development and Environmental Shipping School (IDESS) was established in Sweden and Norway in 1989.

He idea, born out of concern over the consequences of tanker casualties, was to give seafarers access to specialised training that would help to reduce the number of incidents (and minimise their effects) that cause loss of life or damage to the environment. Encouraged by the support of many major shipowners and managers, IDESS sought to improve its training facilities in the Philippines and in October 1995 opened its new, purpose built training centre in Subic Bay. This has proved to be an ideal location providing an excellent environment in which students can acquire skills and knowledge

The new centre represents a considerable investment in modern equipment, teaching aids, and competent instructors, focusing on three main areas of training: Tanker Operations, Safety Training, Simulation, Navigation & GMDSS.
