HST Marine uses Reygar technology to analyze hybrid fleet performance

Swansea-based HST Marine is using Reygar’s BareFLEET technology to understand and report on the performance of its hybrid crew transfer vessels (CTVs).

HST Marine currently has four hybrid CTVs in operation with three more soon to enter service, all of which have BareFLEET installed. These vessels are a mix of controllable and fixed pitch propeller systems that take power from either a high-efficiency electric motor or the main engine, enabling them to operate with zero emissions in electric only mode.

“We recognize the value of gathering and sharing accurate performance data from our vessels,” said Christopher Monan, chief operations officer of HST Marine. “It supports the company in winning new contracts and enables us to build lasting customer relationships.

“We have seen reductions in main engine operation of around 50% on our hybrid vessels, which has the holistic benefits of lowering fuel consumption, emissions and noise when in harbor, as well as lengthening service intervals.

“Being able to demonstrate these efficiency gains with clear and concise performance data is of utmost importance to nurture trust with both new and existing charterer clients, while also providing them with essential evidence for their own environmental reporting.”

New features, developed by Reygar within the BareFLEET technology package, enable HST Marine to closely monitor the performance of hybrid vessels – including, for example, a breakdown of electric versus diesel power consumption while carrying out different tasks offshore.

BareFLEET also monitors the electrical power consumption of the hybrid drive, with specific usage and performance statistics now included alongside conventional diesel engine performance data. These features enable HST Marine to evaluate the environmental performance of hybrid CTVs against conventional vessels and to make adjustments for further improvement.

“The team here is delighted to be supporting HST Marine on its mission to decarbonize offshore marine transportation,” added Chris Huxley-Reynard, managing director of Reygar. “The transition to hybrid CTVs is an important step toward zero-emission targets for the industry as a whole and we have recently delivered a number of BareFLEET systems for new hybrid vessels. It is hugely satisfying to see the technology performing well for HST Marine, providing their teams with the data they need both on board and onshore.”

HST Marine is a wholly owned subsidiary of Purus Wind, part of Purus Marine. It has worked with Reygar since its first vessels went operational five years ago, and has used BareFLEET on all new fleet additions since. The company continues to expand its hybrid CTV fleet with seven new Damen FCS 2710 and three Damen FCS 3210 vessels on order, all of which will be fitted with BareFLEET as standard.
