Expression of Interest (EoI) for
Rig Walking System (RWS) for New Generation (NG) Onshore Drilling Rigs.
Introduction
ONGC is inducting 27 New
Generation (NG) onshore drilling rigs in the NG 1500 and NG/HP 2000 categories,
out of which 17 have been commissioned and the remaining are under rollout.
These rigs are equipped with advanced automation, electro-hydraulic systems,
digital controls and real-time data monitoring facilities.
Except for two Category-I rigs,
they share a common footprint, mast design and general configuration.
Availability of land for new
drill sites has become a constraint in onshore operations.
Therefore ONGC is moving towards
cluster drilling, where several wells are drilled from one site. Here, rig-move
time between wells directly affects rig productivity.
A Rig Walking System (RWS) is a
hydraulically operated lift-move-lower arrangement and is fitted beneath the
rig substructure. It allows the mast and substructure assembly to be moved
between closely spaced wells without a complete rig-down and rig-up. ONGC
expects that such a system could reduce rig-move time and non-productive time
between cluster wells and reduce the safety exposure associated with
conventional rig moves.
A rig walking system has not so
far been deployed on ONGC's rigs. Fitting one to the NG rigs would be a
retrofit, requiring rig-specific engineering of the substructure interfaces,
modifications to the rig, a suitable civil (ground and foundation) interface at
each site, and new operating and maintenance procedures.
ONGC is therefore issuing this
Expression of Interest (EOI) to agencies capable of engineering, supplying,
installing, commissioning and supporting a rig walking system for the NG rigs.
The responses will help ONGC understand the available technologies, the
capability of the market and the practical options for execution.
Under ONGC's procurement
procedure, the information received may be used to finalise the scope of work,
technical specifications, bid structure and bid evaluation criteria for any procurement
that ONGC may decide to undertake later.
Objective
This EOI is intended as a
market-exploration and information gathering exercise through which ONGC seeks
to:
-
Identify
agencies with proven experience in designing, supplying, installing and supporting
RWS for land rigs, particularly as retrofits;
-
Understand
available RWS technologies, including capacities, movement capabilities,
limitations and suitability for NG 1500 and NG/HP 2000 rigs;
-
Understand
the engineering, rig-modification, load-balance and civil-interface
requirements of each technology, including the rig data needed for a retrofit;
-
Assess
agencies' capability to install, commission, operate, maintain and support
geographically dispersed rigs round the clock, including manpower, training,
OEM support and spares;
-
Understand
safety features, operating limits and applicable standards;
-
Obtain
suggestions on technical specifications, scope split, execution and contracting
models, and evaluation criteria;
-
Understand
whether the system is available on hire as well as for purchase, and how hiring
would work in practice; and
-
Gather
inputs for the final scope of work, qualification requirements and procurement
strategy for any future tender.
