Cointegration strategy for damage assessment of offshore platforms subject to wind and wave forces

In structural engineering, offshore structures are undoubtedly among the most exposed to the effects of harsh environmental conditions. The external conditions of these semi-immersed systems involve complex combinations of wave and wind loads. The operating conditions are also unique because oil production platforms are subjected to repeated...

Distributed Dynamic Coordination Control for Offshore Platform Transportation Under Ocean Environmental Disturbances

Transportation of a large offshore platform from inland waters to the open sea is a hazardous and challenging mission. With the development of the autonomous surface vessel (ASV), the problem of large floating object transportation has a chance to be solved by applying multiple physical-connected autonomous tugboats. This article proposes a...

Techno-economic analysis of offshore platforms for green hydrogen production: Dive into system design and costs

The idea behind Power-to-Gas (P2G) is to help provide flexibility to renewable energy sources such as wind farms with intermittent nature. Additionally, hydrogen shows a great potential to help decarbonize several industries and its demand is expected to rise massively. Several studies for the technical and economic feasibility of P2G show...

Recolonization of Offshore Platform

This project is based on 2 issues, the degradation of the ecosystem in North Sea and the decommission of offshore platforms.

Developing the optimal lifting solution for Jumbo to decommission offshore platforms in a single lift

For more than a decade Jumbo has been active on the offshore market performing offshore installation projects with their two DP2 J-class vessels. However, the offshore market is a continuously growing and changing market and in order to keep up with these changes, Jumbo needs to innovate and investigate new activities within this offshore market...

Pioneering Spirit Topside Lift System Interface Design

Pioneering Spirit, Allseas newest vessel, is specialised in offshore platform installation and decommissioning. The goal of this research is to find a solution for the interface between the topside lifting system and platform jacket legs without the necessity of lengthy preparation work to platform. In a research regarding platforms...

Verwijderen van mudcuttings van de zeebodem

Tijdens het offshore boorproces naar olie en gas wordt er een boorspoeling (mud) gebruikt, die onder andere funtioneert als smeermiddel van de boorkop en als transportmedium voor de losgesneden formatie van de bodem van de put naar het boorplatform. Er bestaan verschillende soorten spoeling, de meest voorkomenden zijn de oilbased mud (OBM),...

Pushover analysis of a fixed steel offshore platform - Part I: Beam-column and strut elements in the INTRA program. Part II: Piles and pile groups under extreme loads

Part I: The computer program INTRA models the collapse behavior of trusswork offshore structures with the aid of two types of elements: 'Beam-column' elements, designed to simulate bending dominated failure of structural members, and 'strut' elements, that can represent normal force dominated failure. The behavior of both types of INTRA elements...
