Goldman Sachs appears to have broadened its shipping interests by revealing holdings in John Fredriksen’s Frontline and seismic survey player Magseis Fairfield.

Filings made to the Oslo stock exchange state that the US investment banking behemoth now has 5.26% of the tanker company, a holding worth $150m.

Goldman Sachs also controls 11.29% of Magseis Fairfield.

The disclosures were classed as a “newly disclosable position” as a result of changes to the European Union’s substantial shareholding rules relating to transparency on 1 September.
