ONGC set to float Ratna process platform tender

Indian giant expected to issue documents this month and invite bids for 15,000-bpd facility at fields south-west of Mumbai

India’s state-controlled Oil & Natural Gas Corporation (ONGC) is expected to launch the tender process soon for an offshore process platform that is required for its Ratna and R-series fields off India's west coast.

Project observers said the process platform tender is likely to hit the market later this month and the Indian giant is planning to award the offshore contract before the end of this year.

A source confirmed the development and said ONGC is putting the final touches on the tender documents, after which it is likely to invite offers from international engineering, procurement and construction players.

ONGC had initially planned to charter hire a mobile offshore production unit for the Ratna and R-series oilfields.

Mumbai-based Optimum Oil & Gas emerged as the lowest-bidder in a tender seeking such a unit that was held last year.

However, the Indian giant later cancelled the tender process and decided to commission a process platform instead.

ONGC wants to process about 15,000 barrels per day from the Ratna and R-series fields and requires facilities for water injection of up to 18,000 bpd, industry sources said.

However, the exact processing capacity of the envisaged process platform could not be confirmed by Upstream.

Leading EPC players including Indian engineering giant Larsen & Toubro, domestic player Afcons, Malaysia’s Sapura Energy, McDermott of the US, Abu Dhabi’s National Petroleum Construction Company (NPCC) and Vietnam’s PTSC are some of the players that are seen as likely to be interested in the process platform facility.

NPCC was last year awarded a $330 million contract by ONGC to provide multiple platforms for the Ratna and R-Series project.

NPCC’s workscope involved five new wellhead platforms named R-7A, R-9A, R-10A, E-12B, R-13A as well as associated pipelines and cables.

In addition, more than 140 kilometres of subsea pipelines were also thought to be included.

The Ratna and R-Series fields lie about 130 kilometres south-west of Mumbai, in water depths ranging from 40 to 50 metres.

The offshore fields comprise eight oil-bearing structures, including the R-12 facility.

The more than $600 million Ratna and R-Series development is likely to yield 61 million barrels of oil and 1.696 billion cubic metres of gas on a cumulative basis.

ONGC wants to fast-track oil production from the existing R-12-A wellhead platform — in the Ratna and R-Series field — and the various offshore facilities being set up by NPCC.

In addition, ONGC is also expected to initiate a tender process later this year for a shallow-water gas development centred on its KG-OSN-2004/1 and GS-49/2 assets in the Krishna Godavari basin off the country’s east coast.

The integrated development is a crucial part of ONGC’s strategy to boost production from the asset, with the joint development likely to produce up to 6.5 million cubic metres per day of gas at peak, sources said.

Its offshore workscope is likely to comprise six new wellhead platforms, with a seventh platform also envisaged at GS-49/2, along with several segments of subsea pipelines.
