Oil Rigs and Jack-up Engineering

Service Introduction

Longitude has a recognised track record in marine operations engineering for oil rigs and jack-ups of all types and sizes, supporting operations in oil & gas and offshore wind. We employ advanced analysis and simulation techniques in the design and engineering of offshore oil rig and jack-up operations, mitigating risk from the outset and informing design decisions for enhanced future operations.

Being part of the global consultancy ABL Group, means that we bring to clients a truly holistic service approach, blending our multi-disciplined oil rig and jack-up engineering expertise with more than 40 years of practical experience in rig moving and operations around the world.

This enables us to apply our global service offering via local and often in-country expertise, providing a truly contextual and site-specific analysis, which will in turn support our clients in driving increased value from their assets across their lifespan.

Oil Rig and Jack-Up Engineering Market Challenges

  • Ageing fleet, increasing casualty risk, demand on fleet, and reactivation requests
  • Changing environmental regulations: around carbon emissions and protecting marine ecosystems
  • New and unknown geographies: with more hostile conditions and unknown environmental risks
  • Technological advancements and new risks that these entail
  • Supply and demand imbalance increasing operational delays, costs and potential casualty risks

Our Oil Rig and Jack-up Engineering Services

  • Advanced analysis and simulations:
  • Computational fluid dynamics (CFD)
  • Advanced finite element analysis
  • Multi-body hydrodynamics
  • Dynamic solutions
  • Metocean engineering and analysis
  • Geotechnical and geophysical engineering:
  • Ground modelling and geotechnical interpretation

  • Jack-up leg penetration analysis (LPA)
  • Site-specific geo-risk assessment
  • Seismic engineering and liquefaction analysis

 

Rig moving engineering 

Our approach is designed to assess the suitability of a site for jack-up vessels, providing the following services as part of a location approval for future marine warranty survey (MWS):

  • Leg Penetration Analysis (LPA)
  • Site Specific Assessment (SSA) based on ISO or SNAME Requirements
  • Punch Through Survival and Recovery
  • Dry Transportation Design and Verification
  • Scour and Leg Extraction
  • Site Spot Location Metocean Report
  • Site Zoning and Preload optimisation
  • Leg Seabed Impact Analysis
  • Operability Analysis

For floating units such as drill ships and semi-submersibles, we provide anchor patterns, mooring analysis, line profiles, and riser analysis.

Geotechnical and Geophysical Engineering 

  • Site Characterisation and ground modelling
  • Survey Specification and Management
  • Geospatial data management and analysis
  • Geotechnical Design
  • Leg Penetration Assessment (LPA)
  • Leg Extraction Assessment (LEA)
  • Jack Up Feasibility Study
  • Jacking Gravel Pad Design
  • Scour assessment
  • Seismic engineering and liquefaction analysis
  • Site specific geo-risk assessment
