Passer

Offshore Cable Engineering and Project Management

Engineering services and project delivery for HVAC and HVDC subsea cable projects worldwide.

PASSER provides offshore cable engineering and project management services for cable lay vessel operators, installation contractors and wind farm developers. Our scope covers structural and mechanical engineering, installation feasibility, hazid workshops, lift plans and sea-fastening analysis. We also produce the offshore procedure documentation that keeps complex subsea cable scopes safe and on schedule.

Why Cable Lay Operators and Contractors Choose PASSER

PASSER's team works alongside our equipment manufacturing, fabrication and installation crews. That integration gives clients four practical advantages.

Know-How

Engineers who know the equipment and the operation. Our engineering team has direct experience of the carousels, loading towers and tensioners we design, because PASSER manufactures them in-house.

 

Accountability

Single accountability across the project. Engineering, project management, equipment supply and installation support sit under one contract.

 

Integrated Company

Multi-disciplinary capacity. Three engineering hubs across Norway, the Netherlands and Lithuania cover structural, mechanical, marine and installation disciplines.

 

Documentation Traceability

Procedure documentation that holds up offshore. Hazid workshops and offshore procedures developed for real installation campaigns rather than generic templates.

 

Engineering and Project Management Services

Each service is offered as a standalone scope or as part of a turnkey package.


Structural and Mechanical Engineering

Detailed structural and mechanical engineering for cable handling equipment, transport frames, sea-fastening, deck integration and equipment modifications. Calculations and design work follow DNV verification standards as a baseline, supported by our in-house calculation team.


Installation Feasibility Studies

Independent assessment of cable installation methodologies before tender or capital commitment. Typical scope includes:

  • Cable specification review and bend radius analysis

  • Vessel deck layout and equipment integration assessment

  • Mooring and beaching analysis for shore pull-ins

  • Cable installation analysis for HVAC, HVDC, umbilical and flexible pipe scopes


Lift Plans and Sea-Fastening Analysis

Detailed lift plan engineering and sea-fastening calculations for transit and offshore lifts. Common applications include heavy-lift equipment installation, cable drum and basket transit, and modular spread mobilisation onto cable lay vessels and barges.


Offshore Installation Procedures and Hazid Workshops

Procedure documentation, task plans and hazid workshops drawn from experience on real cable installation campaigns. Our engineering team produces methodology documentation that stands up to scrutiny by marine warranty surveyors and offshore HSE teams.


Project Management and Personnel Support

Dedicated project management across the full delivery lifecycle, with personnel support for offshore installation activities. Typical scope includes: 

Schedule and milestone tracking

Vendor and subcontractor coordination


 

Inspection and test plan oversight


 

Commissioning and handover support

Engineering and Project Management FAQ

What does PASSER's engineering and project management scope cover?

Structural and mechanical engineering, installation feasibility studies, cable installation analysis, lift plans, sea-fastening analysis, hazid workshops, offshore installation procedures and project management for complex subsea cable scopes.

Can PASSER provide engineering support without supplying equipment?

Yes. Engineering and project management services are offered as standalone scopes for clients using third-party equipment, as well as turnkey packages where PASSER also supplies the cable handling equipment.


Do PASSER follow DNV  standards?

Yes. Our service and equipment comes with DNV product certification and/or vertification. The calculations and design work follow DNV verification standards as a baseline. Our Klaipėda fabrication facility holds ISO 9001 (DNV-GL), EN 1090-2 EXC4, ISO 14001 and ISO 45001 certifications.


How quickly can PASSER mobilise?

Subject to scope, our engineering teams in Norway, the Netherlands and Lithuania can mobilise feasibility studies and project support inside a few weeks. Larger scopes typically begin with a kick-off and scoping workshop.
