Seaway 7 – Decommissioning

Seaway Heavy Lifting’s track record of successful project delivery spans two decades, from the North Sea and Black Sea to the Gulf of Mexico, Barents Sea, Malaysia and offshore India. We have installed over 150 platforms and, more recently, hundreds of wind energy foundations. We take pride in meeting exacting demands. With versatile crane vessels and innovative equipment, we ensure timely access to remote deepwater and shallow water frontier locations and optimise the offshore installation schedule.

Seaway Heavy Lifting provides the expertise required for a complete installation scope of work (T&I), with the experience and capacity to achieve project goals regardless of size and complexity. We have built a reputation for success and reliability. Our scope includes amongst others transport and installation of platforms, deepwater structures and platform decommissioning.

Removal and recycling

The removal and recycling of offshore platforms and subsea structures is a major challenge. With over 7,000 platforms in place worldwide, industry and governments face decommissioning costs which may approach USD 200 billion over the next four decades. The majority of smaller platforms – in shallow Continental Shelf areas – are likely to be removed over the next 20-25 years.

Platform abandonments

Seaway Heavy Lifting has the capacity (including single lift solutions) to undertake large-scale platform abandonments. This total service includes preparation, separation, removal, transportation and recycling/disposal ashore. Rigorous safety and environmental standards are applied. Our emphasis is on hazard identification and detailed risk assessment, to resolve issues at the earliest possible stage.

Removal and recycling involves many issues: regulation, technology, environment, planning execution and cost, as a decommissioning project is more than a reverse installation. Regulation is a key factor: decommissioning and removal projects must comply in full with international, regional and national regulatory requirements.
