Our Services
Partner with us for all your Offshore Engineering & Subsea Analysis needs and experience the highest level of service, quality, and dedication in the industry.
Offshore Engineering
Installation Analysis and Planning
We simulate and optimize offshore installation operations including vertical and horizontal subsea connections, flexible and rigid pipeline pull-ins, lifting operations (both offshore and onshore), and flexible pipe handling on vessel decks. Our work ensures safe, efficient, and cost-effective installation strategies.
Riser Design and Analysis
We provide dynamic analysis of riser systems (SCRs, lazy waves, and more) under complex environmental conditions. Using OrcaFlex and advanced statistical methods like EHMP and irregular sea state analysis, we design risers to meet fatigue life requirements and operational demands.
Power Cable and Flowline Assessment
We conduct global analysis for power cable installations and subsea flowline expansions and crossings, delivering comprehensive technical feasibility studies tailored for offshore wind and oil & gas projects.
Subsea Analysis
Fatigue and VIV Analysis
Our services include detailed fatigue assessments for risers and subsea structures, addressing fatigue contributions from waves, vortex-induced vibrations (VIV), and heave VIV. We ensure asset longevity through high-accuracy, high-confidence analysis.
Riser Interference and In-Place Analysis
We evaluate riser-riser interference and perform in-place analyses of subsea connections to guarantee system integrity and operational safety over the project lifecycle.Hydrodynamic Studies
Comprehensive studies to assess the impact of underwater currents, soil conditions, and other environmental factors on subsea
