Offshore wind

We offer fit-for-purpose consultancy to projects within offshore wind both fixed and floating structures, as well as we develop R&D concepts that benefit the growing offshore renewables industry. Semar offers its competence and experience earned from the offshore oil & gas industry to multiple wind farm projects. The feedbacks we get are that the way we work, based on team collaboration and multi-discipline approach combined with specialized competences, help efficiently address the specific challenges and demands of the offshore renewables industry.

Honeymooring

Our innovative solution Honeymooring™ is a unique and cost-effective way of mooring floating wind turbines in a “honeycomb” network using, flexible lines and active sharing of anchors and buoys.

Lifting Operations

We have more than 25 years of experience in lifting of structures and bridge components

Marine Transportation

Our experience in transporting rigs and various offshore structures, using both barges and heavy-lift vessels, spands over 25 years

Suction Anchor Design

From our experience in diverse offshore installations, Semar has designed several suction anchors as fixed and moored foundations

Coupled Analysis

We perform coupled analyses to support component design or plan marine operations. We herein describe Semar’s capabilities within coupled analyses of offshore floating or bottom-fixed wind turbine systems.
