Use of “Black-Box” Reviews in PHA Scenario Development and Validation Against Vessel Limits

ABSTRACT: This presentation will review examples of fitness for service limitations and the potential process safety hazards presented if exceeded.  The use of the “black-box” historical operating data review methodology in PHA scenario development and validation will be...

Development of a Real-Time Riser Fatigue Monitoring System

ABSTRACT:   As risers are deployed into deeper water, they are subject to increasingly severe environmental loading due to ocean currents and surface weather.  Analytical models of these risers often predict premature failure due to the required safety factors and...

Wind Testing of a Dual Derrick

ABSTRACT Wind loading on drilling rigs is covered by API Specification 4F 3rd Edition, Specification for Drilling and Well Servicing Structures. The specification gives procedures for determining design wind loads on new drilling rigs. These wind loads impose significant loads on...

Riser Concepts for High Motion Vessels in Ultradeep Water

ABSTRACT: The paper addresses early work executed during the research study for RPSEA project 10121-4401-01 Ultra-Deepwater Riser Concepts for High Motion Vessels. The steel catenary riser is the simplest riser configuration but has limitations when attached to a high-motion...

Floating/Swivel Top-load Testing and Simulation- A Novel Approach for Evaluating Unit Load Stability at the Early Stage of Primary Package

ABSTRACT: A novel floating/swivel platen approach is proposed in this paper for primary package top-load evaluations. Different from the conventional fixed platen top-load practice, this approach, which frees the translational (floating) and rotational (swivel) degrees of the...

Drilling Riser Fatigue Monitored in Real Time Aboard Drillship

ABSTRACT: A riser-fatigue monitoring system (RFMS) has been developed to provide field measurements of drilling riser stress and fatigue in near-real-time. During the two deployments on the Chikyu drilling riser, the system successfully recorded riser dynamics in the field,...

Developments in High Temperature Assessment

ABSTRACT: Two new assessment methods are suggested for high temperature components. First, in addition to creep damage, the calculation of the rupture failure probability rate provides information on the changes in risk over time. This is particularly helpful for aging components...

Metallurgical Examination of Impulsively Loaded Vessels

ABSTRACT: Establishing design and inspection criteria for impulsively loaded vessels requires a precise understanding of the damage mechanisms and failure modes experienced by the vessels. To that end, Stress Engineering Services, Inc. performed a metallurgical examination of...
