RS breaks cover on ice
Te Russian Maritime Register of Shipping (RS) continues to push forward to operate in ice-covered waters.
and gas production units RS has emphasised its forward looking role in the field. Significantly, the new Rules include
I
requirements for the design, construction and operation of floating offshore units for drilling, production, treatment, storage, refining and offloading hydrocarbons. These requirements are based both upon the international experience of construction and operation of the units and upon the experience of RS in the classification and construction of ships, mobile offshore drilling units and fixed offshore platforms. Te Rules include requirements for low
temperature resistance in the materials used during construction and structural strengthening for ice loads. Te choice of the
n completing the development of new rules for the classification, construction and equipment for floating offshore oil
material (steel) for ice strengthening is crucial. So, RS has conducted a range of research on steel performance during long-term operation at very low temperatures, including brittle fracture resistance assessment in welded structures to be used on the Arctic shelf, thermo-mechanical steel strengthening technologies, and complex assessment of the efficiency of new low temperature-resistant steel grades intended for Arctic structures. The prospective development of
hydrocarbon fields in areas with permanent ice coverage will require technologies able to perform underwater (under-ice), including systems for processing and offloading hydrocarbons extracted with the help of such technologies. RS is conducting research in to safety standards for underwater production facilities and offloading systems during design and operation.
Unsurprisingly RS focuses on ice operations,
as over 90% of ships under construction to RS class are ice strengthened. Protecting the safety of life in harsh conditions, RS has also developed additional winterisation requirements. The requirements consider protection from icing and optimisation of ship’s structure, equipment and systems for long-term operations at low temperatures. Ships complying with the ice protection
requirements may be assigned additional anti-ice notations. RS gave special consideration to ships with
the distinguishing mark WINTERIZATION and the certification of materials used for manufacturing elements of equipment, fittings and other products installed on the open deck and providing safety of navigation, environmental protection and other specific purposes. NA
