Offshore vessels

With many decades of experience in the maritime and offshore industry, our offshore vessels are designed with maximum efficiency in mind. This is achieved by integrating controls and mission equipment, and optimising the vessel itself.

Based on the company’s extensive experience, the hull has been optimised, using CFD tools and model testing to accomplish low resistance during transit, while still retaining excellent sea- and station-keeping capabilities.

Our vessels are created with people in mind, so they can work safely, efficiently and experience a high level of crew comfort.

Pipelay vessels

Our pipelay vessels are built to suit specialist requirements and specifications with full integration of the pipelay equipment, either provided by third-party suppliers or ourselves. We design the vessels in close cooperation with our customers, which results in an effective customised design fit for the most efficient operations.

We have a proven track record for the delivery of flex-lay and reel-lay vessels. These include SEVEN WAVES, SEVEN PACIFIC, SEVEN OCEANS, SEVEN SEAS, SEVEN RIO, SEVEN SUN, SEVEN CRUZEIRO, SAPURA DIAMANTE, SAPURA TOPAZIO, SAPURA ONIX, SAPURA JADE and SAPURA RUBI.

Offshore support vessels

Our portfolio of multipurpose offshore support vessels is suitable for a wide range of activities such as inspection, maintenance and repair work, as well as construction and field support operations. These offshore support vessels are developed to meet the requirements of both the offshore oil and gas, and offshore wind industries.
