This boat has been designed for long range crew changes between shore and offshore platforms, typically between 30 and 200 Nautical miles from shore. Its design and equipment is the results of several iterative loops to meet oil majors and ship owners requirements:
• Standard equipment, high load factor engines rating and business class seats
• Designed for existing boatlanding and crane set ups : manoeuvrability at low speed, structural strength and geometry (size, position of cargo area, vision)
• Engine replacement possible with the boat in the water

As operability and safety are major concerns, A2V has developed tools to evaluate seakeeping behavior and obtain an operability envelope for a given area of operation. This methodology has been reviewed and refined with DNV’s ship hydromechanics department as part of a Joint Development Program.
It shows a very high operability at 60 knots in Angola, as well as a very robust “safe mode” at 18 knots in case of severe conditions thanks to the high crossdeck and high structural strength.

Fuel costs to transport 150 PAX on 300 Nautical miles 8 000 $ 25 000 $

A2V-60-CB carries 60 pax at 60 knots, this means a rate of
3600 pax. Nm / Hour. 36 m Monohull Crewboat transport 45
pax at 40 knots, 1800 pax. Nm / Hour.
This means that an A2V-60-CB is equivalent to two 36 m
monohull crewboats, with a shorter time to destination for
passengers and fuel costs divided by 3 !
In addition to the savings of buying and using one vessel
instead of two,

Fuel savings above 4 Millions dollarsper year per vessel
