The patented Hull Vane® is a proven energy-saving and seakeeping device to achieve the highest level of performance on intermediate-speed vessels. The Hull Vane® consists of a transom-mounted submerged wing - or hydrofoil -, which converts energy of the stern wave into forward thrust. It reduces fuel consumption between 5-25%, emissions, powering requirements, noise and motions in waves.

This thesis performs a technical, economical and environmental feasibility study of three dense hydrogen carriers as a fuel to power the largest semi-submersible offshore crane vessel in the world – Heerema’s Sleipnir.

The Alfa Lift, a new build heavy lift crane vessel owned by Offshore Heavy Transport, is on track to enter service by early 2022. The vessel features a 3,000 ton main crane, 10,000+ m² smart deck which can be fully submerged to a depth of 15 meters and a electric-hybrid battery system made by Kongsberg.

In 2020, Wärtsilä was awared a combined contract by Therma Marine Inc. (TMI) for a barge-mounted 54 MW / 32 MWh energy storage system. The power barge consists of ten Wärtsilä GridSolv Max systems, supported by the the GEMS energy management platform. Total costs of this power barge are estimated at €16M for the battery packs plus €8.1M for the power equipment excluding engineering and installation.
