Sakhalin-2 Project envisages stage-by-stage development of Piltun-Astokhskoe oil and Lunskoe gas fields.
The plan for the realization of the first stage envisaged the installation of the modernized Molikpaq Platform with new technological
equipment providing the drilling and production of oil (PA-À Platform), single point mooring and storage tanker for intake and offloading of oil. In the
area of Piltun - Astokhskoe field sea depth reaches 30 m, for this reason the intermediate spacer had to be designed and manufactured.
In 1997 by the order of SEIC CDB ME "Rubin" developed the design of steel substructure for Molikpaq offshore
ice resistant fixed platform which construction was successfully completed by Amur Shipbuilding yard in 1998. The manufacturing of substructure
blocks and design works were carried out simultaneously.
The substructure – spacer – presents a steel structure 110 õ 110 m, height 16 m and weight about 15000 t. The spacer mating with
modernized Molikpaq Platform was performed in the Republic of Korea. The successful completion of this complicated operation proved the correctness of
technical solutions laid in the spacer design by CDB ME "Rubin".
In July 1999 the platform produced the first oil, thus becoming the first successful joint project within the framework of Product
Sharing Agreement related to Sakhalin-2 Project concluded between the Government of the RF and consortium of foreign companies.
For the modernization of Molikpaq platform CDB ME "Rubin" also developed the workshop documents for Water Flood Module
which construction and testing were completed in 2002 at Amur Shipbuilding Yard.
Starting from 2000 within the framework of Sakhalin-2 Project CDB ME "Rubin" participates in conjunction with AMEC (UK)
in design of new gas and oil production platforms for Lunskoe (LUN-A Platform) and Piltun-Astokhskoe (PA-B Platform) fields.
The participation of CDB ME "Rubin" along with other Russian design agencies started form the preparation of special technical
requirements and feasibility studies for the project and also adjustment of design methods and specifications to Russian norms and regulations. Also
the conceptual designs of platform substructures and the evaluation of the major stages of offshore operations were made.
In 2003 - 2005 CDB ME "Rubin" on assignment of AMEC carried out the detail design of accommodation modules of the
topsides of the platforms LUN-À and PA-B. The design was carried out using 3D modelling.
Starting from the stage of topsides construction of the platforms LUN-À and PA-B at the shipyard of the company Samsung Heavy
Industries (Republic of Korea) the specialists of CDB ME "Rubin" being a part of AMEC group carried out the technical support of the
construction.
During 2006 CDB ME "Rubin" participated in the design activities with the aim to prepare "AS built" documents
for LUN-A and PA-B Platforms for further use during their operation.
Currently, CDB ME "Rubin" participates in the design activities related to prospective licensing areas of Sakhalin
Shelf.
