Hamburg: Classification society Germanischer Lloyd has published a new set of rules for ships intended for offshore support and supply, offshore towing, well stimulation, and other specialized offshore services. Compared to their predecessors, these ships are larger, more specialized, and technically more sophisticated to meet demands of complex deepwater field developments, it says. The latest review of the OSV rules are therefore intended to support design and build safer and more robust offshore service vessels while minimizing operational risks.
Under GL's new Rules for Hull Structures of Offshore Service Vessels which come into force next month, the class notation 'OFFSHORE SERVICE VESSEL' will be assigned, complemented by optional further notations, such as HNLS for ships carrying hazardous and noxious liquid substances, AH for anchor handling tug/supply ships, WSV for well stimulation vessels, and WTIS for wind turbine installation/construction support ships.
Today's expanded definition of an OSV includes not only traditional supply boats, but also anchor handling tug/supply ships, well stimulation ships, standby ships, and even ships built to carry hazardous and noxious substances, to fight fires, or to occasionally recover oil. Wind turbine installation ships are also covered, points out GL.
The new Rules for Offshore Service Vessels, I-6-1, Hull Structures, are posted on GL's website www.gl-group.com . [29/12/09]
