New Anchor Handling notation

� Requirements to the arrangement are introduced, and mandatory equipment:- Anchor handling winch*- Shark jaw*- Towing pins* - Stern roller* Requirements for DNV certification

� Functional based definitions of equipment to accommodate new solutions

� Specific requirements to the equipment introduced, with possibility for accepting equivalent solutions

� Maximum loads and specifications such as emergency capabilities of the equipment are to be specified by the owner/yard/manufacturer

� The actual specifications of the equipment shall be posted on the bridge

� Requirements to breaking strength of the wire are removed

� SiO survey requirements introduced

Main focus: enable increased crew awareness of the actual capabilities of the installed equipment

What are the consequences?�A typical AHTS previously with Tug and Supply Vessel Basic

or Supply Vessel notations will be entitled the following notations:

✠✠✠✠1A1 Offshore Service Vessel AHTS1A1 Offshore Service Vessel AHTS1A1 Offshore Service Vessel AHTS1A1 Offshore Service Vessel AHTS

�Upon request from the Owner, existing vessels may be entitled the new notations



11

Updated Tug Notation� Tug is defined as a ship type notation,

while Towing is an additional notation related to Offshore Service Vessel

� Tug notation will in most cases be superfluous for a typical AHTS due to the introduction of the new notations

The notation has been revised with the following main changes:�Updated testing requirements and bollard pull procedure�Documentation requirements have been revised �Towing arrangement and stability requirements have been revised�SiO survey requirements introduced�Towing arrangement drawing to be posted on bridge



12

Dynamic Positioning Systems� DNV is developing new DP- notations customised for markets where the

DYNPOS- standard is considered beyond the actual needs

� The new DP- notations will also be based on the principles in IMO MSC/Circ. 645 “Guidelines for vessels with dynamic positioning systems”

� The existing DYNPOS- notations are unchanged

� The DYNPOS- notations have additional requirements as compared to the DP- notations

� Class entries to the DYNPOS- series:- Documentation review, performance testing and FMEA failure testing

� Class entries to the DP- series:- Based on a corresponding, valid and maintained DP class notation, from the

losing society
