About Poseidon Offshore Energy

Who We Are

Poseidon Offshore Energy B.V. provides specialist offshore and marine engineering for contractors, vessel owners and project teams across Europe.

Based in Rotterdam, we support transportation and installation scopes, structural analysis and detailed design, cable installation engineering, hydrodynamic analysis, naval architecture and vessel modifications.

Clients work directly with experienced engineering personnel throughout the assignment, enabling clear communication, responsive technical support and practical deliverables aligned with the project’s design, fabrication, mobilisation and offshore installation requirements.

We start by understanding the technical requirement, available project information, applicable design criteria and the intended use of the deliverables.

The scope, assumptions, interfaces and responsibilities are agreed before the main engineering work begins. Engineers with the appropriate discipline expertise are then assigned according to the requirements of the assignment.

Analysis and design are developed in close coordination with the client’s technical team.

Deliverables are prepared for practical use within design development, fabrication, mobilisation or offshore installation.

To provide focused offshore and marine engineering that helps clients solve technical challenges, strengthen project capacity and develop practical solutions for design, mobilisation and offshore installation.

To be a trusted European engineering consultancy recognised for technical competence, responsive support and direct involvement in offshore energy and marine projects.

How We Work

Our Mission

Our Vision

To be a trusted European engineering consultancy recognised for technical competence, responsive support and direct involvement in offshore energy and marine projects.

Our Core Principles

Multidisciplinary Expertise

Project-specific engineering resources are assigned across structural, marine, installation and related disciplines according to the requirements of each assignment.

Practical Offshore Experience

Engineering decisions are informed by practical understanding of vessel operations, fabrication, mobilisation and offshore installation.

Innovation & Precision

Application of advanced engineering software and data-driven project control tools.

Safety & Quality First

Engineering deliverables are developed in alignment with international standards and QHSE compliance.

Future-Ready Solutions

Engineering support is adapted to evolving offshore technologies, vessel requirements and project-specific installation challenges.

Technical Capability Areas

Our senior specialists combine decades of international experience across Oil & Gas, Offshore Renewables, and Marine Engineering sectors.

Transportation & Installation Engineering

Engineering for the transportation and offshore installation of structures, subsea assets and project equipment. Typical support includes transport configurations, vessel suitability, installation sequences, load cases, operational limits, installation procedures, interface reviews and offshore-readiness documentation.

Structural Analysis & Detailed Design

Structural analysis and detailed design for offshore structures, temporary works, equipment foundations, vessel modifications and installation systems. Capabilities include global and local analysis, finite-element modelling, strength and fatigue checks, deck assessments, reinforcement design, support structures, fabrication drawings and material take-offs.

Cable Installation Engineering

Engineering for offshore power, telecommunications and subsea cable installation, recovery and repair activities. Capabilities include cable-lay analysis, installation tension assessment, bend-radius verification, overboarding, touchdown behaviour, suspended spans, pull-in engineering, shore approaches, cable handling, burial assessment and installation procedures.

Hydrodynamic & Installation Analysis

Hydrodynamic assessment of vessels, floating structures and offshore installation systems under environmental loading. Capabilities include vessel-motion analysis, RAOs, operability studies, wave-response assessment, tow and transport analysis, mooring response, dynamic installation analysis, rigging design, weather-window assessment and definition of limiting environmental criteria.

Vessel Modifications & Mobilisation

Naval architecture and marine-engineering support for vessel suitability, modification, loading and mobilisation. We develop layouts and integration solutions for offshore equipment, including deck reinforcements, foundations, equipment supports, cable-handling systems and temporary utilities. Deliverables may include fabrication drawings, installation details and as-built updates.

Electrical, Instrumentation & Control Engineering

Electrical, instrumentation, automation and control support for offshore facilities, vessel modifications and temporary project systems. Capabilities include electrical load definition, cable routing, field instrumentation, control valves, I/O lists, instrument indexes, control philosophies, Cause & Effect diagrams, PLC, SIS and ESD interfaces, hazardous-area considerations, vendor reviews, FAT support and commissioning input.

Process, Piping & Layout Engineering

Process, mechanical, piping and layout engineering for offshore facilities, vessel modifications and project equipment integration. Capabilities include P&ID review, piping design basis, line and tie-in lists, equipment specifications, hydraulic assessment, piping classes, plant and deck layouts, 3D modelling, pipe routing, flexibility and support considerations, fabrication isometrics, test packages, material take-offs and as-built documentation.
