Energy & Renewables

Supporting New Zealand’s offshore energy and renewables sector.

Seaworks has a 30-year record of providing integrated (and ISO-certified) vessel and subsea services and support to New Zealand’s offshore energy and renewables sector.

We offer and operate a comprehensive range of vessels and subsea remotely operated vehicles (ROVs) that are well suited to New Zealand’s coastal and offshore conditions. They include our DP1 ROV support vessel (Seaworker) and a hydraulic work-class ROV (Quasar 6). We also undertake subsea ROV-enabled pipeline and cable inspections, with a proud record of more than 3,000 kilometres of inspections to date.

In the past 20 years, Seaworks has worked at all New Zealand’s offshore energy fields. Our projects have included installing the first meteorological buoys, undertaking preliminary field surveys and providing ongoing routine field support, such as line-boat services and personnel transfers. We’ve also helped to execute science-based subsea inspection programmes, platform supply and cargo transfers and field decommissioning projects.

Seaworks were the marine contractors for project West Wind providing comprehensive marine support, including specialist cargo transport of turbine and field components across Cook Strait to the project wharf facility.

We also offer integrated solutions for offshore field operators via highly qualified onshore and offshore personnel and our fleet of vessels and ROVs. Our crew includes vessel marine crew, dynamic position operators, ROV supervisors, ROV pilot technicians, hydrographic surveyors, subsea inspection engineers, offshore project managers, protection officers and CSR personnel.

Case Studies

Submarine Cables

Transpower Cable Installation

When an ageing fibre-optic cable located on Cook Strait’s seabed needed to be removed and replaced, the Seaworks team contributed specialist expertise, extensive experience and purpose-specific equipment to get the job done.

MBIE Tui ROV Survey

When the New Zealand Government took on the massive job of decommissioning an offshore oil field, it appointed Seaworks to take a preliminary deep dive – gathering key data and samples that would be used when assessing the scope and costs of the work and appointing contractors to undertake it.
