Performance management for new shuttle tankers

Performance management for new shuttle tankers
Teekay has ordered four new North Sea shuttle tankers from Samsung Heavy Industries with hybrid propulsion

Wärtsilä subsidiary Eniram will supply vessel performance management systems to four shuttle tankers Teekay has ordered from Samsung Heavy Industries in South Korea.

These tankers will each have a data collection platform that enables managers to monitor the performance of the ships and optimise their operations. Data will be streamed to shore managers for analytics and reports.

Eniram’s performance management units should ensure that managers can achieve the full potential of the vessel within the fleet. Ship data can also be combined with weather and sea condition information to provide accurate performance analytics.

This is part of a much wider suite of systems and products Wärtsilä is supplying for Teekay’s new gas-fuelled shuttle tankers. Each ship will have systems for storing, piping and using liquefied natural gas (LNG) for propulsion and station keeping. Each shuttle tanker will have a dynamic positioning (DP) system to DP2 class for positioning offshore during loading operations.

Wärtsilä is supplying the LNG packages and energy storage devices as part of a hybrid propulsion system, which will also include Wärtsilä 34DF dual-fuel gas engines and a new version of a volatile organic compound (VOC) capture system.

This uses the VOC gas that evaporates from the oil cargo tanks during loading for propulsion instead of venting it to the atmosphere.

Teekay plans to use these shuttle tankers in the North Sea, most likely in the Norwegian sector because the VOC capture technology reduces carbon tax payments in that country’s offshore jurisdiction.

In November 2017, Wärtsilä Marine Solutions president Roger Holm explained how the company had been working with Teekay on the shuttle tanker technologies. During a media presentation he unveiled the company’s smart marine ecosystem vision and described the technology developed by Eniram.

Riviera Maritime Media and Marine Electronics & Communications is hosting the European Dynamic Positioning Conference in London on 6 February as part of a week of conferences, seminars and awards.
