Kirinskoye is the first offshore field in Russia to utilise a subsea system for natural gas production. The field holds over 100 billion cubic metres of gas and 11.4 million tonnes of gas condensate.
The Kirinskoye gas and condensate field is part of the 'Kirinsky block' in the Sea of Okhotsk and is one of the main development priorities for Gazprom, the world's largest gas producer.The field is part of a Russian Federation strategy for development of an integrated gas production, transportation and supply system to the regions of Eastern Siberia and the Far East. 

Challenged by the weather

The area is part of the Arctic region, with up to seven months of ice cover per year, and is located 28 kilometres offshore the island of Sakhalin in the Sea of Okhotsk. Here, the wind is strong, and vigorous waves or ice make it difficult to work offshore most of the year, which is why this project was carried out during the short summer period. Because of the weather conditions, one of the most important tasks was to act fast and precise.

Development of the installation

Ramboll was engaged by MRTS, a major Russian subsea service company, to perform critical installation analysis and assist in the development of the installation procedures for the challenging Okhotsk Sea conditions. MRTS holds the main contract from Gazprom for installation and service for the Kirinskoye field. 

Services provided

Ramboll carried out critical installation analyses and assisted in developing the pipeline installation procedures for the challenging Okhotsk Sea conditions. This included state-of-the-art dynamic finite element modelling of the pipeline installation. The purpose of the dynamic analyses was:

  • To identify the location for davit cranes on deck of the vessel and their individual wire length at all times during the pipeline deployment operations.
  • To identify needed vessel movement to avoid over-stressing the pipeline during the deployment operations.
  • To establish the amount of fatigue introduced in the pipeline due to the installation process.
  • To determine the maximum allowable wave height for the installation operation.
  • Furthermore, 3D modelling and finite element analyses of spools based on metrology and operational requirements were prepared to ensure successful fabrication and installation of tie-in spools.

Worth knowing about the project:

  • The Russian Federation government appointed Gazprom to coordinate the implementation of the Eastern Gas Programme. The programme takes into consideration potential gas exports to China and other Asia-Pacific countries (Eastern Gas Program).
  • The Sakhalin III project is planned to become one of the main sources of gas supply for these regions (the Sakhalin – Khabarovsk – Vladivostok gas transmission system) and for the above-named export.
  • Gazprom holds licenses for three blocks within the project: Kirinsky, Ayashsky and Vostochno-Odoptinsky and for the Kirinskoye gas and condensate field.
  • Gas resources of the Sakhalin III project are estimated at some 1.4 trillion cubic metres. The bulk of them are concentrated in the Kirinsky block.
  • The Kirinskoye gas and condensate field is a top development priority in the Kirinsky block.
