DNV DNV-RU-SHIPS PART 6 CHAPTER 19 PDF

Application

The rules in this chapter apply to vessels arranged with alternative propulsion in addition to the main propulsion.

In the context of these rules the term propulsion system incorporates both propulsion and steering function.

Compliance with AP-1(a%)(+), AP-2(a%)(+) or AP-3(a%)(+) notations will, to a varying degree, provide additional measures to enhance the safety of the ship with respect to grounding risk and the probability of reaching

safe harbor of refuge after a single failure in the main propulsion system and its auxiliaries. Exceptions are made for failures in acceptable common active and passive components as given by these rules.

The notations for alternative propulsion are only valid with both propulsion systems intact.

The requirements in these rules are supplementary to the main class rules.
