EnCana Corporation is proposing to develop its Deep Panuke gas prospect located offshore Nova Scotia, approximately 44 km to the West of Sable Island. The proposed development plan comprises three new platforms - a Process Platform (PP), a Utilities and
Quarters Platform (UQP) and a Wellhead Platform (WHP) - with two interconnecting bridges linking them to each other. Up to 6 wells will provide production from the Deep Panuke development. Gas will be delivered to shore via one new export pipeline, of
24" NPS after processing offshore. The onshore landfall site for the export line will be in the Goldboro region.
EnCana Corporation has appointed Accent-Saipem Energy Joint Venture to provide the Engineering Design study for this project.
During this phase we are seeking qualified companies for the following scope of supply:
Transport & Installation (T&I) of the jackets, piles and topsides structures.
SCOPE OF WORK
The T&I scope covers the transport and installation of the three platforms. The Wellhead Platform (WHP) jacket and topsides will be installed in advance of the main facilities to enable drilling and completions to be performed from a jack-up rig. The
Process (PP) and Utilities/Quarters (UQP) platforms will be installed approximately one year after the wellhead platform.
The Wellhead Platform is to be a steel structure fitted out primarily with clad carbon steel flowlines, well fluid manifolds, hydraulic power packs and tubing for Xmas tree control, E&I rooms, platform crane and safety equipment. It shall be supported on
a steel jacket with four skirt piles and linked to the processing platform via a steel bridge.
The Process Platform comprises a fully integrated steel topsides deck supported by steel jacket and two skirt piles on each of the corner legs. The process platform also has a cantilevered flareboom, which shall be installed as a separate lift.
The Utilities and Quarters Platform comprises a two level steel utility deck which supports the living quarters and which in turn is supported by a steel jacket and four skirt piles. The completed structure shall be lifted from the utility deck using an
arrangement of slings and a loose spreader bar positioned above the quarters module. The platform is linked to the processing platform via a pedestrian and utilities bridge.
The anticipated overall dimensions and lift weights (excluding rigging) of the three platforms are as follows:
It is anticipated that all jackets shall be constructed and transported vertically.
The following equipment and services are to be provided by the T&I contractor:
- engineering services to develop detailed procedures for the safe and efficient execution of the work;
- suitable cargo barges, towing gear and tugs to transport the platform components and the bridges from their fabrication sites to the offshore location;
- fully certified rigging (slings, grommets, shackles, etc.) required for the lifts;
- a marine spread capable of performing all installation operations required at site, including seabed surveys, manoeuvring of cargo barges, lifts, jacket positioning, levelling, pile driving and grouting operations;
- all ancillary services required to complete the offshore work safely and to the satisfaction of EnCana Corporation, the Canadian Regulatory Authorities and the Marine Warranty Surveyor, including standby vessels, surveying, ROV operations, grout
monitoring and testing, scaffolding, welding, NDE, and weather forecasting.
