INTRODUCTION
Jascon 31 is a DP-3 Support / Hook Up / Accommodation Barge for Deep / Shallow Water
Operations. It’s a highly versatile multipurpose vessel equipped with A1 Floatel facilities
and is capable to support, General Offshore construction activities, provide extensive
accommodation support for field / hook up support, Diving support and Sub-sea
installation work. The Barge is fitted with a heavy duty 400 tonne active heave
compensated general purpose offshore construction crane with underwater capabilities.
The tall crane combined with the long boom makes it well suited to reach over offshore
platforms or to stab over 70 m long jacket piles.
This specification may be read in conjunction with the following drawing:
Drawing No.: J31 101-010 HA,R21, ML6003-101-010 GENERAL ARRANGEMENT
The Barge is provided with electric driven thrusters to assist the Kongsberg Dynamic
Position System and classed as ABS DP-3 Barge. The Helideck is suitable for Sikorsky S92A
Helibus and compliant with CAP437 and ABS Classification Rules.
A 42 m long hydraulic heave compensated Aluminium Gangway is provided for personnel
transfer to the Offshore Platforms and FPSO Vessels.
The main Hull, Accommodation block and all Equipment on the Barge are fully compliant
with the Fire Safety and Life Saving requirements accordance with the latest SOLAS,
Statutory and ABS Classification Rules and Regulations.
SOLAS compliance is as applicable for Barges operating Offshore.
