Class notation for the bridge design on offshore service vessels.
Purpose
The notation sets a standard that aims to reduce the risk of human error in bridge operations, both when navigating the ship from the forward bridge and when handling the ship from the aft bridge.
Benefits
Collisions, groundings and contact incidents amount to approximately 50% of all serious ship casualties. The majority of theses are categorised as human error. After being found compliant with the rules, the ship will be assigned the NAUT-OSV(A) class notation, which is compliant which is highly recognised within the offshore service industry.
Features
The class notation denotes that the bridge has been designed in accordance with established functional requirements and principles and ergonomic principles for reduced workloads and improved operational conditions. Furthermore, that the bridge arrangement provides the information and equipment required for the safe performance of the functions to be carried out at dedicated workstations.
The addresses class notation operations in all waters, including under harsh conditions such as in the North Sea area.
The DNV Rules for Nautical Safety - Offshore Service Vessels (NAUT-OSV) stipulate functional requirements for the:
Design of all workplaces relating to navigation and offshore operations on the bridge, including the location of necessary equipment
Bridge working environment
Range of instrumentation needed for the various operations
Performance of equipment, based on its specific function and purpose
Ergonomics and human/machine interface
- Testing and trials
Process
Approval of drawings and technical documentation
On board testing of equipment
