Another attempt to carry out a $1.5bn IPO of Topaz Energy & Marine is reportedly being considered by Oman’s Renaissance Services.

The OSV owner could be listed in London next year, according to sources cited by Bloomberg.

Goldman Sachs and Morgan Stanley have been linked to the sale as advisers.

The banks are not commenting. Dubai-based Topaz also declined to comment.

No final decisions have been made, with valuation and location still under discussion, the report said.

Topaz chairman Samir Fancy said in its 2017 annual report: “Topaz and its shareholders believe that it is the right time to consider the company’s strategic options in relation to growth and capital enhancement.

“All options are being considered, including inorganic and capital market transactions such as an offering of securities."

Previous deal failed

Renaissance pulled a planned London IPO in 2011 over valuation concerns and growing regional unrest. The implied valuation was between $1.5bn and $1.9bn.

Renaissance bought Topaz through a share swap in 2005.

The OSV company is one of a handful that has not restructured financially during the offshore slump.

The fleet of 89 ships includes anchor-handlers, heavy deck-cargo units, multipurpose support vessels, platform supply vessels and emergency response ships.

Its second quarter net loss was $1m, against $10m in the same period of last year.

Revenue jumped to $85m from $57m, with growth supported by increasing investment by energy companies in exploration, production and development
