n Brazil, the consideration of collision-worth ships is of crucial importance to minimize or prevent potential damages to the load and environment, especially given the recent government investments to accelerate the growing of the petroleum sector (PROMEF, Programme for Modernization and Expansion of the Brazilian Fleet) and taking into account the increasing world demand for safety at sea and protection of the environment, especially after the disaster of the Exxon Valdez tanker. The grounding of the tanker Exxon Valdez in 1989 in the coast of Alaska is considered as the largest oil spill catastrophe due to the destruction of hundreds of kilometers of ecosystems in a virgin coastline, leading USA to impose the double hull for tankers. In 1992, The International Maritime Organization (IMO) established the requirement of double hull in the International Convention for the Prevention of Pollution from Ships (MARPOL). Such a new design diminished the structural damage in ship collision incidents, but in some cases it was not enough to prevent critical damages. For this reason, some countries adopted particular measures in tanker ship projects to enhance further ship safety.
