2H provides end-to-end transportation and installation (T&I) engineering services to ensure the safe, efficient, and reliable delivery of offshore structures and systems from fabrication yards to their final offshore locations.

Our engineers bring decades of experience supporting complex offshore wind and oil and gas developments — from early planning and detailed analysis through to offshore execution. With a deep understanding of marine operations and structural behavior, we deliver optimised solutions that reduce risk, enhance efficiency, and ensure the integrity of critical infrastructure during every phase of transport and installation. 

Our Capabilities 

We manage and engineer all aspects of T&I operations, including: 

• Project management from planning to execution 

• Engineering analysis for all T&I phases 

• Development of detailed T&I procedures 

• Specification and procurement of T&I aids and equipment 

Systems Expertise

Our extensive track record covers the full range of offshore systems, including: 

• Fixed Jackets and Conductor-Supported Platforms: Heavy-lift, jack-up rig, launch, and float-over installations. 

• Subsea Structures: PLEM/PLET, suction piles, SUTA/SDU, flying leads, and trees. 

• Umbilicals, Risers, and Flowlines: installation of flexible and steel catenary risers, umbilicals, hybrid and top-tensioned systems, and drilling and completion risers.
