The Rapid Response Damage Assessment program (RRDA) is an organized team of engineers, naval architects, master mariners and support staff that respond 24/7 to ship related emergencies such as grounding and collision. Enrollment of a vessel in RRDA ensures direct access to technical support that is needed during vessel casualties. When activated, RRDA is an extension of the vessel management team’s own response capability, focusing on the measure of changes occurring to hull strength, stability and the extent to which risk of pollution can be mitigated.

Regulatory Requirements and Industry Guidelines

RRDA complies with the following regulations and industry guidelines:

  • MARPOL Regulation 1/37(4), as circulated by resolution mepc.117(52), all oil tankers of 5,000 tonnes deadweight or more shall have prompt access to computerized shore-based damage stability and residual structural strength calculation programs.
  • MARPOL 73/78 Annex I, Regulation 26 requires a shipboard oil pollution emergency plan (SOPEP) for all tankers of 150 gross tons or more and all other vessels of 400 gross tons or more.
