2.0 INTRODUCTION

2.1 Purpose & Scope of this Document

This Specification defines the minimum technical requirements for the design; manufacture,testing and commissioning of the Jacket Upend Control System (UCS) on the Eldfisk II 2/7SJacket structure and the supply of 4 No. ROV operated flood valves for the Bridge SupportJacket structure

The 2/7S Jacket is an 8-leg structure with 2 No. Flotation Tanks. All jacket legs will be floodedduring installation to achieve upending and obtain on-bottom stability. The 4 main legs will besubdivided into 3 compartments. The 4 internal legs will not be subdivided. Each of theFlotation Tanks will be subdivided into 15 compartments. The structure is designed to bebarge launched.

The Bridge Support Jacket is a 4-leg structure, which is designed to be lift installed. All jacketlegs have single compartments and will be flooded during installation to assist on-bottomstability.

Note: This document primarily specifies the technical requirements for the UCS on the 2/7SJacket structure

The technical requirements for 4 No. ROV operated flood valves and for the sling retainer /release hydraulic mechanism for upper trunnion required for the Bridge Support Jacketstructure are detailed in Appendix 4 and Appendix 11 of this Specification.

Both jackets will be installed in the Norwegian sector of the North Sea; the approximate waterdepth at the offshore installation site is -75.0m.

2.2 Eldfisk II Field Development

ConocoPhillips, on behalf of the PL018 license, plans to design, construct and install thefollowing new facilities at the Eldfisk Field:

A new wellhead, process and accommodation platform designated 2/7Ssupported by a steel jacket,

A new bridge system linking the 2/7S platform to the existing 2/7E platform. Thebridge system comprises two bridges and an intermediate bridge support. Thebridge support comprises a jacket sub-structure and Topside with flare facilities,

Modifications necessary on the existing Eldfisk Complex installations, Eldfisk 2/7Band Embla 2/7D to facilitate continued operations of exiting facilities and for theintegration of the new 2/7S platform,

New pipeline connections from 2/7S to the existing oil and gas export pipelinesdownstream of 2/7B to Ekofisk Complex,

New subsea power and control cable between 2/7S and an external source.

The new 2/7S platform will be the new field control centre for Eldfisk Complex. The existingplatforms at the Eldfisk Complex will be converted to not normally manned facilities, to beoperated and controlled from the new 2/7S platform.

The illustration below gives an indication of the new facilities and the existing Eldfisk Fieldfacilities.

4.0 BASIC DESIGN INFORMATION

4.1 Design Life

The Supplier shall design the UCS to meet the Project requirements. The UCS supplied to therequirements of this Specification shall be used to assist in the installation of the Jacketstructure detailed in section 2.1 of this Specification.

The DCC, UIP, HPU, PMC, Hydraulic Jacks, Umbilicals and Winches shall be designed andmanufactured for a minimum design life of 5 years and shall be removed from the InstallationVessel or Jacket after Jacket installation on the seabed.

The remaining components of the UCS may or may not remain in situ. The Jacket legcompartment Flood and Vent Valves shall not be removed and must therefore be designed tohave a minimum 40 year, in situ, service life. The Flood and Vent Valves shall remain in the‘closed’ position to prevent long term egress of biocide from the leg compartments.

4.2 Environmental/Installation Data

At the Jacket fabrication site prior to loadout the Upend Control System will be exposed to asevere sea/air environment for a period of up to 12 months.

During installation several components of the UCS (i.e. flood & vent valves, tube bundles,electrical cables, pressure sensors, hydraulic jacks and umbilical interface panels) shall beimmersed in seawater and may remain in this situation for a number of days before use.These components shall therefore be capable of withstanding a hydrostatic pressure of 0.98MN/m2 (this value has been derived to account for the field water depth plus 100 year stormwave crest elevation).

Climatic conditions at the fabrication site and offshore installation site are given below:

ConditionLocation

Offshore Installation Site Fabrication Site

Air Temperature -7.9ºC to +28ºC +5ºC to +35ºC

Sea Temperature +2.6ºC to +20.0ºC -

Relative Humidity 25% to 100% 25% to 100%

Atmosphere Salt LadenSalt laden and corrosive.

Wind driven dust.

It should also be noted that equipment located on the outside of the Jacket structures mightalso be subject to direct radiant heat from the sun, which could generate temperatures as highas +80°C (maximum). The Supplier should take particular note of this high temperaturerequirement particularly when selecting materials and designing the UCS.

5.0 2/7S JACKET TECHNICAL REQUIREMENTS

5.1 General

After completion of the Jacket at the Jacket Fabrication site, the Jacket with Flotation Tanks

installed (each one located at opposite sides of the Jacket structure) shall be loaded out onto atransportation / launch barge in preparation for transportation and offshore installation.

Prior to load-out the UCS shall be functionally tested and commissioned by the UCS Supplierwith the assistance of the Jacket Fabricator. After completion of the testing andcommissioning, each Jacket leg and Flotation Tank compartment shall be filled withcompressed air to a pressure of 0.05 MN/m2 by the Jacket Fabricator. The compartmentpressures shall be monitored by the UCS to confirm the integrity of each compartment. Anongoing daily check* on the compartment pressures versus ambient temperatures shall becarried out after jacket load-out, during transportation to the offshore site and prior to jacketlaunch. Monitoring cables accessible from the deck of the barge shall be provided for thispurpose (cable specification shall be in accordance to Appendix 7 of this Specification).

Monitoring of the Jacket leg compartments shall also be carried out during jacket installationonto the seabed. Note: the Supplier shall also provide an option for monitoring the FlotationTank compartment pressures during installation of the jacket onto the seabed i.e. prior toremoval of the Flotation Tanks from the Jacket structure when the tanks shall be underwater.

During any storage period on the transportation / launch barge and during transit to theoffshore site the hydraulic system maybe subject to thermal effects. The Supplier shall designthe UCS system such that these thermal effects cannot cause premature opening of theJacket and Flotation Tank flood valves.

* Any variations in the pressure measurements prior to offshore installation shall be discussedwith the site team / designer / installation contractor and remedial action agreed.

The UCS shall be designed to control a series of flood and vent valves on the Jacket legs andnominated Flotation Tank compartments, allowing the flooding of buoyancy compartments in apre-planned sequence, such that the Jacket maintains integrity and stability throughout thecomplete upending and setting down operation.

The Jacket is designed to be barge launched and the top of the Jacket (launch frame) willsubmerge to approximately 55m water depth. After completion of the launch the Jacket willfloat at approximately 11.7º to the horizontal and will then be towed to the Installation Vessel(IV) to commence the upending and set down operation.

Once the main lifting slings are connected to the IV crane, the primary electro-hydraulicUmbilical, which shall be located on the deck of the IV shall be reeled off its Storage Winchand manoeuvred over to the Jacket structure where itwill be manually connected to theUmbilical Interface Panels (UIP). The IV crane shall assist with handling the Umbilical onto theJacket structure. Buoyancy (floats) aids shall be supplied to assist with handling the Umbilical.The floats shall be capable of being attached / detached as necessary during deployment andrecovery of the Umbilical.

The primary electro-hydraulic Umbilical shall also be connected to the DCC located adjacentto the Umbilical Storage Winches on the deck of the IV. The purpose of the Umbilical / DCC /HPU is to provide means of opening and closing the valves and to monitor Jacket andFlotation Tank compartment pressures and valve position data.

The Jacket shall be installed using a combination of the IV crane and controlled flooding andventing of Jacket leg and nominated Flotation Tank compartment valves from the DCC locatedon the deck of the IV.

th July 2012

The UCS is required to achieve the final Jacket vertical position prior to installation on theseabed. The set-down operation will be carried out using the IV crane. Limited ballasting maybe required during this operation for trimming the Jacket.

Any lights and cameras to be used during the set-down operation shall be provided by ROV’s.

After the Jacket is on the seabed the UCS shall be used to complete the flooding of the Jacket

leg and nominated Flotation Tank compartments to assist with on-bottom stability prior topiling. The primary electro-hydraulic Umbilical shall be disconnected and recovered to thedeck of the IV after the Jacket leg-flooding operation is completed and prior to removal of theFlotation Tanks.

The flotation tanks shall be removed from the jacket one at a time using the IV crane after the jacket has been set down on the seabed (before the piling operation). To assist with theremoval operation each tank shall be equipped with one hydraulic wedge release jack, whichshall be operated from top platform of the jacket (El +22.00m) using the UCS HPU orInstallation Contractor provided HPU. Once the flotation tanks are removed from the jacket,they will have to be fully drained and back-loaded onto a transportation barge.

Any equipment that is left permanently installed on the Jacket after its installation shall berated for 100m water depth to allow for the 100 year wave condition.

5.2 Jacket Configuration

The Jacket structure is designed to be barge launched and installed in 75m water depth in theNorwegian sector of the North Sea.

The general configuration of the Jacket and the UCS are shown on Project drawings. Specificreferences to Jacket leg numbers and buoyancy compartment numbers quoted below can be

found on schematic drawing:

ELDS-DR-S-00099-001 Jacket Flooding Schematic

The estimated upper bound dry weight of the Jacket structure is 13,200 tonnes. Actual weightwill be confirmed on detailed weight reports issued for the Jacket structure.

Each Jacket corner leg (A1, A2, D1 & D2) has 3 buoyant floodable compartments. The innerand outer launch truss legs (B1, B2, C1 & C2) have 1 buoyant floodable compartment each. All Jacket pile sleeves shall be free flooding. Each Flotation Tank has 15 buoyant floodablecompartments. Three compartments on each tank (C5, C10 & C15) shall require controlledflooding using flood and vent valves. The remaining tank compartments shall be flooded using

rip-out diaphragms, supplied by others.

The UCS shall incorporate a status monitoring system to ensure that the upending operationteam is aware of the integrity of the Jacket / Flotation Tank floodable compartments and theopen and closed positions of the flood and vent valves.

The data shall be transmitted from the pressure sensors and valve position indicators to theUIP via pre-installed electrical cables and from the UIP to the DCC via the primary electro-hydraulic Umbilicals.

From EL+0.00m (LAT) to the top of the Jacket is 24.50m (24.50m above MSL) afterinstallation, prior to cutting.
