Class notation for nautical safety aiming to reduce the risk of collisions and groundings.

Purpose

Statistics show that collisions and groundings amount to almost 50% of all serious ship casualties and most of these incidents are further categorised as being due to human error.

The main objective of the NAUT-OC notation is to reduce the probability of human errors through redundant sensor information at workstations supporting the view necessary for maintaining proper look-out in accordance with COLREG72.

Benefits

The NAUT-OC notation enables the officer of the navigational watch to maintain full control of all the bridge functions he/she is responsible for, including the look-out function, when navigating in ocean and coastal waters.

Modern navigational equipment is getting increasingly more complex and our NAUT-experts are for this reason doing design assessment of navigational systems and equipment integration as well as overseeing proper testing prior to ship delivery. Independent studies conclude that there is a significant reduction in the risk of collisions and groundings for ships having DNV additional class notations for nautical safety.

Features

The notation sets a bridge standard aiming to reduce the risk of human failure in bridge operation irrespective of the navigational watch being performed by a single navigator or a larger bridge team.

In this context the requirements are governing both technical and human related topics concerning factors affecting safe performance of the bridge operation, (except for the human himself), e.g.;

  • wheelhouse design workstation arrangement
  • navigational equipment
  • human-machine interface
  • working environment,

and more, to ensure a reliable bridge system in various modes of operation.

Process

"Since 1988 all new SeaTrans ships have been built according to DNV's nautical safety class. Operating these ships, there has been a substantial reduction in groundings and a considerable reduction in insurance premium."
