Offshore Development

Wärtsilä offers efficient, reliable and environmentally sound solutions for Offshore Service Vessels (OSV) engaged in field development activities. Wärtsilä has the capability to follow an offshore service vessel (OSV) project from the design phase starts and throughout the project's lifecycle.

Wärtsilä delivers proven design, engineering, products and concepts, which we integrate into an environmentally and economically sound total ship solution. Our worldwide service network will provide service and support for the full lifetime of the vessels.

    Offshore Support Vessels

    We provide total integrated solutions for all types of offshore support vessels (OSV):

    • AHTS – Anchor handling tug supply vessels
    • PSV – Platform supply vessels
    • OCV – Offshore construction vessels
    • DSV – Diving support vessels
    • Seismic research vessels
    • Jack-up vessels.

    The varying operational modes, conditions and requirements of OSVs require a unique design in order to achieve high fuel efficiency in all situations. Wärtsilä designed OSVs have the highest possible Environmental Regularity Number (ERN), which represents the vessel’s capability for maintaining its position and normal operations under certain weather conditions.

    Within the offshore service vessel market we deliver diesel mechanic solutions, diesel electric solutions and hybrid solutions, depending on the functionality of the vessel. The performance of electrical machinery can be further enhanced through Wärtsilä’s patented Low Loss Concept, which reduces transformer losses in electricity transmission systems. This improves the returns on diesel-electric machinery, making it an even more attractive choice for OSVs.

    In addition, for service vessels we also offer a large range of engine room pumps, valves, sewage treatment systems, and fresh water makers, all designed for easy operation, high efficiency, and quick service turnaround.

    We also provide training and Condition-Based Maintenance, with excellent spare part availability from a wide range of manufacturers.
