BWMS bucks the trend of problematic operations

A BWMS has demonstrated its reliability in the face of a survey which exposed the systems as problematic and inoperable.

Optimarin’s 334m3 capacity BWMS installed onboard Neptune Subsea’s IMR vessel Larissa has only seen 140 hours of operation since it was fitted in 2010, but despite this, a recent maintenance check showed it is in full working order.

Per Ivar Fagervoll, CEO of Golden Energy Offshore, which manages the ship for Neptune, explained: “Since delivery Larissa has been working consistently for super majors in the North Sea and West Coast of Africa. However we, and the previous ship managers, haven’t really needed to run the BWT system.

“So when the Optimarin team came on board we thought it might have issues. Little did we know… the guys pressed the ‘start button’ and it came into action immediately – smooth operation and no problems at all.”

The show of competency comes as ship owners and operators reported in an American Bureau of Shipping (ABS) survey that 43% of BWMS are either inoperable or have problematic operations.

Referencing the ABS survey, Tore Andersen, CEO at Optimarin, commented: “The BWT sector is maturing but some suppliers have seen it as a business opportunity, rather than an area demanding specialist focus and expertise.”

Mr Anderson added the BWMS onboard Larissa has no moving parts, requires minimal maintenance and is flexible enough, due to its modular nature, to fit any specialist vessel.
