Calibration of Jackup Leg Foundation Model Using Full-Scale Structural Measurements
The fitness of jack-up rigs to operate in varying water depths and weather conditions is determined by "site-specific" structural assessments. These assessments are conducted by a wide range of companies...

Heave Compensated Landing System - A Novel Tool for Subsea Intervention
This paper presents a new intervention system that allows the use of a low cost workboat to deploy and recover delicate payloads in subsea installations. Vessel motions are decoupled from the subsea package...

Appraisal of Lightweight Moorings for Deep Water
This paper outlines the potential advantages of using lightweight fiber ropes for mooring floating production platforms. The influence of tether properties on mooring system response is discussed. It is...

A Preliminary Case for the Existence of Hurricane Alleys in the Gulf of Mexico
A review of hurricance intensity in the Gulf of Mexico suggests there are two alleys where hurricanes are roughly 20% more intense than elsewhere. This paper develops a physical basis for the alleys using...

Design of Submarine Pipelines Against Upheaval Buckling
This paper describes part of a comprehensive joint-industry project on upheaval buckling. It develops a semi-empirical simplified design method and detailed design methods based on a new numerical analysis,...

The Joint Industry Development of a Recommended Practice for the Site Specific Assessment of Mobile Jackup Units
The mobile self-elevating (drilling) unit, or jack-up, has been central to the exploration and development of offshore oil and gas reserves. In recent years there has been an increased...

A Simple Model to Predict Soil Resistance to Driving for Long Piles in Deepwater Normally Consolidated Clays
As the exploration and development for offshore oil and gas reserves moves into the deepwater environment of the continental slope, a good model is necessary to evaluate drivability of...

Pipe Characteristics
Microtunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...

Pipe Design
The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors:...

Field Aspects
As soon as practical after their arrival at the project site, all pipes, fittings, and appurtenances should be thoroughly checked for compliance with the contract documents and accepted...

Contract Documents
As with any civil works project, the bid and contract documents prepared by the owner and the engineer should provide the contractor with the necessary information to prepare bids, to...

Shafts/Temporary Structures
Shafts should be of a size to accommodate the equipment and pipe selected and to allow for safe working practices. If the shaft must accommodate the permanent works, it is the contractor's...

Construction Support Services
A preconstruction survey of existing structures within the anticipated construction zone of influence should be conducted before any construction begins. A plan for structures that need...

Measurement and Payment
The owner shall establish a bid schedule to obtain pricing for all work associated with the microtunneling installation. This bid schedule provides the bidders the opportunity to establish...

Restoration and Cleanup
