The Emergency Response Service (ERS) is aimed at providing a speedy assessment of the stability and longitudinal strength of a damaged ship in an emergency event. All salient data of the vessels relating to the main hull and its components is stored in computer system along with the loading guidance and strength data.  In the event of an emergency, the assessment is carried out using the stored data and details of the damage sustained by means of in- house Computer Software.
