Remote Visual Inspection Joint Industry Project

The United Kingdom, Health and Safety Executive (HSE) is conducting research in a Joint Industry Project (JIP) aimed at providing a stronger understanding of both the benefits and limitations of RVIs and develop a set of best practices when conducting these types of inspections. The JIP will:

  1. Assess current technologies and practices
  2. Conduct RVI trials for probability and detection
  3. Determine the human factors and competence assessment
  4. Develop a good practice guide and methodology for demonstrating competence for RVI 

Effects of Damping Properties of Anchoring Systems, Tension Legs, and Risers on Fatigue, Longevity, and Life Extension Decisions

To study the effects of damping properties of anchoring systems, tension legs, and risers on fatigue, longevity, and life extension decisions. The study will include empirical evaluation and modeling for tthe effects of damping properties, incldueing potential reduction in fatigue among other effects.
The study will evaluate potential effects of damping properties and their direct implications for platform and riser life extensions and factors that could affect life extension determinations.

Total contract award, including options, is $324,867.00

Decommissioning Methodology and Cost Evaluation for Alaska OCS Region Offshore Oil and Gas Gravel Island Facilities

The objective of the study is to provide the BSEE Alaska Region with research and cost estimating regarding decommissioning a typical arctic, gravel island-based, oil and gas exploration/production facility. The study will consider standard industry practice, available technology, current regulations, and market conditions.

TAP-690-The Effect of Deformation Damage on the Mechanical Behavior of Sea Ice: Ductile-to-Brittle Transition, Elastic Modulus and Brittle Compressive Strength

The study will examine the effects of deformation damage on the mechanical behavior of sea ice and whether such deformation lowers ice strength. Offshore exploration and production structures must be designed to resist forces and damage that result during contact with wind-driven floating ice sheets.

TAP-695-Slug Loading and Response in Pipeline (SLARP) JIP

The overall description of the proposed research is to investigate and conclude current state of industry practice and technology gaps with respect to evaluating slugging effects on pipeline, spools and riser, to investigate alternative methodologies analysis methods for defining slug and turbulence loading and assessing structural response in pipeline and spool and riser, to develop best practices guideline for modeling and analysis of slug and turbulence loading and response of pipeline, spool and risers.

TAP-696-Short Crest JIP: Effect of Short-crestedness on extreme wave impact

This project is the brainchild of the CresT JIP. The central question of the CresT JIP was What is the highest (most critical) wave crest that will be encountered by a platform in its lifetime? In July 2010 the CresT JIP was completed and resulted in a number of important and practical recommendations for the wave and crest heights to be used in floating platform design.

TAP-703-Design and Operation Practice for Arctic Mooring Systems JIP

1) Developing a design and operation practice document based on existing technology, industry experience, and consensus building. This document can be used as:

  • A foundation document for developing industry standards such as an Arctic supplement to API RP 2SK or ABS guidance notes
  • A foundation document for developing company specific design and operation guidelines

2) Providing a forum for the industry and regulators to exchange information/ideas and work together to build consensus.
3) Developing a proposal for further joint industry work

TAP-708-Hydrodynamics of Disconnectable Turret Systems (DISCO)

There has been a growing number of projects in the offshore industry that use disconnectable buoy systems. The advantage of such a system is that in case a large hurricane or typhoon is moving towards the FPSO it can be disconnected from its risers and mooring quickly to avoid any damage to the facility. In this disconnection phase the turret buoy is detached from the vessel and drops to a safe depth of 100-200m below the surface. The FPSO is then moved to a safe area until the storm has passed by.

TAP-716-Reliability-Based Sea-Ice Parameters for Design of Offshore Structures

The objective of this project is to produce information that will facilitate strict implementation of the ISO 19906 Standard: Petroleum and Natural Gas Industries - Arctic Offshore Structures (i.e., the Normative). The information will consist of sea-ice information, for U.S. waters in both the Chukchi and Beaufort seas, in a format consistent with the philosophy of the Normative.
