RINA approves new OSV rules and Environment notations
International classification society RINA has launched
new rules for Offshore Support Vessels, new environmental notations covering
cargo handling and transhipment operations and a new guide on complete ship model calculation of passenger ships.
All these initiatives were approved at a
meeting of RINA’s technical committee held in Genoa this week.
The free-standing and user-friendly Offshore Support Vessels (OSV) Rules have been
developed in response to requests from shipyards and operators.
Ships complying with the new rules are assigned the Service Notation Offshore Support Vessel followed by at least one of the following service features defining the specialised service:
supply for OSVs specially intended to provide facilities and assistance for the
performance of offshore activities.
tug for OSVs specially equipped for towing.
salvage tug for OSVs specially equipped for towing having
specific equipment for salvage.
escort tug for OSVs specially equipped for towing and having specific equipment
for escorting ships or other units during navigation.
fire-fighting for OSVs specially intended and equipped for
oil recovery for OSVs specially equipped with fixed
installations and/or mobile equipment for the removal of oil from the sea
surface and its retention on board, carriage and subsequent unloading.
diving support for OSVs equipped to support diving
operations, which are provided with a diving system.
cable laying for OSVs specially equipped for the carriage
and/or laying, hauling and repair of submarine cables.
pipe laying for OSVs specially equipped for the carriage
and/or laying, hauling and repair of submarine pipes.
In addition, in order to better describe the specific technical
capabilities, equipment and arrangements, RINA has established a number of
additional service features and additional class notations that may be assigned
to an OSV, such as anchor handling
and dynamic positioning.
RINA has introduced new requirements for the certification and the
evaluation of the environmental impact of dry cargo handling systems. These
respond to demands from transhipment and bulk port operators in sensitive areas
which wish to demonstrate environmental responsibility and high standards of
minimising airborne pollution from cargo handling.
The following two new additional class notations may be granted:
GC CARGO HANDLING (Green and certified cargo handling
to ships provided with systems for handling
solid bulk cargo which may be source of sea or air pollution (e.g. those
handling coal, iron ore, sulphur, etc,), designed, tested and installed according to Part F Ch 7 Sec 6 to minimize
their environmental impact.
- intended to operate at a fixed location
- complying with the provisions for the
assignment of the GREEN PLUS notation and
- complying with the provisions for the
assignment of the GC CARGO HANDLING (Green and certified cargo
handling systems) notation.
Guide on Complete Ship Model Calculation of Passenger Ships
RINA has launched a guide aimed at shipyards and ship
designers which details the procedures for the structural analysis of passenger
The structural arrangement of passenger ships
presents significant differences with respect to other ship types, the most
important being the presence of several decks contributing to the hull girder
The contribution of each deck to the
longitudinal strength strictly depends on the actual arrangement and cannot be
evaluated on the basis of a simplified beam analysis. The level of contribution
of each of these elements is to be obtained through a finite element analysis
of the whole ship.
The purpose of the Guide is to detail the
procedure for the above analyses, taking into account the general arrangement
of the longitudinal elements (side, decks, bulkheads) and the specific
characteristic of passenger ships (windows, openings, recesses, pillaring
The new rules and amendments will enter into force on
1 July 2013 and 1 January 2014 and will be available on www.rina.org.
